Qingqiao Specialized Production Line for Drying Chinese Medicinal Herbs In the realm of traditional Chinese medicine (TCM) processing, the drying stage stands as a critical determinant of herbal quality, efficacy, and shelf life. Recognizing this pivotal role, Qingqiao has engineered a state-of-the-art specialized production line dedicated exclusively to drying Chinese medicinal herbs, merging time-honored TCM principles with cutting-edge technological innovation. At the core of Qingqiao’s solution is a multi-stage drying system meticulously calibrated to address the unique characteristics of different herbs. Unlike generic drying equipment that applies uniform heat, this production line features customizable temperature, humidity, and airflow parameters, ensuring optimal preservation of active ingredients such as alkaloids, flavonoids, and volatile oils. For heat-sensitive herbs like mint and honeysuckle, the line employs a low-temperature air circulation mode (35–45°C) to retain delicate aromatic compounds, while hardy roots such as ginseng and astragalus undergo a gradual temperature ramp (50–60°C) to remove moisture deeply without causing cell wall damage. The production line’s structural design reflects a deep understanding of herbal processing logistics. It comprises automatic feeding conveyors with variable speed controls to prevent bruising of fragile herbs, followed by multi-layered drying chambers equipped with stainless steel mesh belts that ensure uniform exposure to drying air. A key innovation is the heat pump technology integrated into the system, which achieves energy efficiency up to 30% higher than conventional electric or gas-powered dryers. This not only reduces operational costs but also minimizes carbon emissions, aligning with modern sustainability standards. Qingqiao’s drying line incorporates intelligent control systems that set it apart in the industry. Equipped with precision sensors and a user-friendly HMI (Human-Machine Interface), operators can pre-program drying protocols for over 200 common medicinal herbs, with options to store custom recipes for rare or proprietary blends. Real-time monitoring of moisture content—measured via near-infrared (NIR) spectroscopy—eliminates the guesswork traditionally associated with drying, ensuring each batch meets the strict moisture levels (typically 8–12%) required for long-term storage and efficacy retention. Versatility is another hallmark of this production line. It seamlessly handles various herbal forms, including whole plants, slices, powders, and extracts, adapting its drying parameters accordingly. For example, thin slices of rhizomes like ginger require shorter drying cycles with increased airflow, while dense roots like rehmannia benefit from longer, gentler heating phases. This adaptability makes it an invaluable asset for TCM manufacturers, herbal farms, and pharmaceutical companies seeking to process diverse product lines with consistent quality. Quality control is embedded throughout the production 流程 (process). The closed-loop drying environment prevents contamination from external pollutants, while advanced filtration systems ensure clean air circulation. Additionally, the line’s uniform drying capabilities eliminate issues like uneven moisture distribution, which can lead to mold growth or degradation of active components. Post-drying, herbs retain their natural color, aroma, and therapeutic properties—a critical factor for both traditional practitioners and modern consumers. In an era where TCM is gaining global recognition, Qingqiao’s specialized drying production line bridges traditional wisdom and technological advancement. It not only enhances the efficiency and reliability of herbal processing but also upholds the integrity of medicinal herbs, ensuring they deliver their intended therapeutic benefits. Whether for small-scale herbalists or large pharmaceutical operations, this production line represents a commitment to quality, sustainability, and innovation in the vital field of Chinese medicinal herb processing.   https://account.bossgoo.com/products/productUpdate?id=68281348 https://account.bossgoo.com/products/productUpdate?id=68281288 https://account.bossgoo.com/products/productUpdate?id=68281277

Cyclone dust collector efficiency factors 1, air inlet   The inlet of the cyclone dust collector is the key component to form the rotating airflow, which is the main factor affecting the dust removal efficiency and pressure loss. Tangential air inlet area has a great influence on the dust collector, the air inlet area relative to the cylinder cross-section is small, into the dust collector of the tangential velocity of the airflow is large, and is conducive to the separation of dust. 2、Cylinder diameter and height   A, the diameter of the cylinder is composed of cyclone dust collector ^ basic size. The tangential velocity of the rotating air flow on the dust generated by the centrifugal force and the cylinder diameter is inversely proportional to the same tangential velocity, the smaller the cylinder diameter D, the smaller the radius of rotation of the air flow, the particles are subjected to the centrifugal force is greater, the easier the dust particles are arrested set. However, if the cylinder diameter is too small, the wall and the exhaust pipe are too close, the particles are easy to escape; the cylinder diameter is too small, but also easy to cause clogging, especially for viscous materials. When dealing with a large amount of wind, because of the small diameter of the cylinder to deal with dusty air is limited, several cyclone dust collector can be used in parallel operation method to solve the problem. Parallel operation of the air volume handled by the dust collector for the treatment of the sum of air volume, resistance is only a single dust collector in the treatment of that part of the air volume it bears the resistance. But the parallel use of manufacturing is more complex, the materials required are more, the gas is easy to be blocked at the inlet and increase the resistance, therefore, parallel use should not be too many units. B, the total height of the cylinder refers to the height of the dust collector cylinder and cone body two parts of the sum. Increase the total height of the cylinder, can increase the number of rotating circles in the dust collector, so that the dust in the dusty airflow and airflow separation opportunities, but the total height of the cylinder increases, the radial velocity of the centripetal force in the external cyclone so that some of the fine dust into the internal cyclone of the opportunity to increase, thereby reducing the efficiency of dust removal. The total height of the cylinder body is generally 4 times the diameter of the cylinder body is appropriate, cone cylinder part, because of its radius continues to decrease, the tangential velocity of the airflow continues to increase, the dust to reach the outer wall of the distance also continues to decrease, dust removal effect is better than the cylinder body part. Therefore, in the case of a certain total height of the cylinder, an appropriate increase in the height of the cone part of the cylinder, is conducive to improving the dust removal efficiency, the general height of the cylinder part of the diameter of 1.5 times, the height of the cone for the diameter of the cylinder 2.5 times, you can get a more satisfactory dust removal efficiency. 3, exhaust pipe diameter and depth Exhaust pipe diameter and insertion depth of the cyclone dust collector dust removal efficiency has a greater impact. Exhaust pipe diameter must choose a suitable value: exhaust pipe diameter decreases, can reduce the rotational range of the inner cyclone, dust is not easy to discharge from the exhaust pipe, is conducive to improving the dust removal efficiency, but at the same time the outlet velocity increases, the resistance loss increases; if you increase the diameter of the exhaust pipe, although the resistance loss can be significantly reduced, but due to the exhaust pipe and the wall of the cylinder is too close to the formation of inner and outer cyclone easy to form a “short circuit” phenomenon, make the cyclone dust collector, the dust removal efficiency. Short-circuit" phenomenon, so that part of the external cyclone has not been removed in the dust directly mixed into the exhaust pipe discharge, thereby reducing the dust removal efficiency. It is generally believed that the diameter of the exhaust pipe for the cylinder diameter of 0.5 ~ 0.6 times is appropriate. Exhaust pipe inserted into the shallow, easy to cause the inlet dusty airflow directly into the exhaust pipe, affecting the dust removal efficiency; exhaust pipe inserted into the deep, easy to increase the friction surface of the airflow and the pipe wall, so that the resistance loss increases, at the same time, so that the distance between the exhaust pipe and the bottom of the cone is shortened, increasing the chance of the second return of the dust mixing discharged. Exhaust pipe insertion depth is generally slightly lower than the bottom of the air inlet position is appropriate. As the cyclone dust collector unit steel consumption is relatively large, so in the design of the program is a better way from the upper part of the cylinder down the material from thick to thin gradually decreasing! Maintenance of cyclone dust collector 1、Stabilize the operating parameters Cyclone dust collector operating parameters mainly include: dust collector inlet air velocity, the temperature of the treated gas and the inlet mass concentration of dusty gas. 1) Inlet air velocity. For the cyclone dust collector with certain size, the increase of inlet airflow velocity not only improves the processing gas volume, but also effectively improves the separation efficiency, but the pressure drop also increases. When the inlet air velocity increases to a certain value, the separation efficiency may be reduced, wear and tear, shorten the service life of the dust collector, so the inlet air velocity should be controlled in the range of 18~23m/s. The inlet air velocity should be controlled in the range of 18~23m/s.   2) The temperature of the processed gas. Because the gas temperature increases, its viscosity becomes larger, so that the centripetal force on the dust particles increases, so the separation efficiency will decrease. Therefore, the dust collector operating under high temperature conditions should have a larger inlet gas velocity and a smaller cross-section flow rate.   3) Inlet mass concentration of dusty gas. High concentration of large particles of dust on small particles of dust have obvious carrying effect, manifested in the separation efficiency. 2、Prevent air leakage   Cyclone dust collector once the wind leakage will seriously affect the dust removal effect. It is estimated that the dust collector under the cone or ash discharge valve leakage of 1% dust removal efficiency will fall by 5%; leakage of 5% dust removal efficiency will fall by 30%. Cyclone dust collector has three kinds of leakage parts: inlet and outlet connecting flange, dust collector body and ash unloading device. The reasons for air leakage are as follows:   1) The air leakage at the connecting flange is mainly caused by the bolt not being tightened, uneven thickness of the gasket, uneven flange surface and so on.   2)The main reason for air leakage at the dust collector body is wear and tear, especially the lower cone. According to the use of experience, when the gas quality concentration of dust exceeds 10g/m3, in less than 100 days can wear out 3mm steel plate.   3) The main reason for the air leakage of ash unloading device is the poor sealing of mechanical automatic (such as heavy hammer) ash unloading valve.       3、Prevention of key parts of the wear   Factors affecting the key part of the wear and tear are load, air velocity, dust particles, wear parts of the shell, cone and dust discharge port and so on. Technical measures to prevent wear include:   1) Prevent the dust discharge port from being blocked. The main method is to choose high-quality dust discharge valve, and strengthen the adjustment and overhaul of dust discharge valve in use.   2) Prevent too much gas from flowing back into the ash discharge port. Use of the ash discharge valve should be tight, properly weighted.   3) Frequently check the dust collector for leakage due to wear and tear, so as to take timely measures to put an end to it.   4) In the dust particles impact parts, use the wear-resistant plate can be replaced or increase the wear-resistant layer.   5) Minimize the welds and joints, must have the welds should be ground flat, flange stop and gasket of the same diameter and keep good alignment. Selection of cyclone dust collector precautions 1. The selected cyclone dust collector has small resistance loss, low power consumption, simple structure and easy maintenance. 2. When the temperature of dusty gas is very high, the cyclone dust collector should be equipped with heat preservation facilities to avoid the condensation of moisture in it and affect the dust removal effect. 3. The amount of purified gas of cyclone dust collector should be consistent with the actual amount of dusty gas to be processed. Select the cyclone dust collector diameter should be as small as possible, if you require a larger through the air volume, you can use several small diameter cyclone dust collector in parallel is appropriate. 4. When the gas contains flammable and explosive dust, the cyclone dust collector should be equipped with explosion-proof device. 5. Cyclone dust collector can capture ^ small dust particles should be slightly smaller than the size of the dust in the gas being treated. 6. The seal of the cyclone dust collector should be good to ensure that there is no air leakage. 7. Cyclone dust collector inlet wind speed should be kept 18~23m/s, too low when the dust removal efficiency decreased: too high when the resistance loss and power consumption should be increased, and dust removal efficiency is not obvious       

Introduction to centrifugal fans   Centrifugal fan is a kind of slave fluid machinery which relies on the input mechanical energy to increase the gas pressure and discharge the gas. Centrifugal fans are widely used for ventilation, dust removal and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced draft in boilers and industrial furnaces and kilns; cooling and ventilation in air-conditioning equipment and household electrical appliances; drying and conveying of grains; and inflation and propulsion of wind tunnels and hovercrafts.       Working Principle   Centrifugal fan is based on the principle of conversion of kinetic energy into potential energy, using high-speed rotation of the impeller to accelerate the gas, and then decelerate, change the direction of flow, so that the kinetic energy is converted into potential energy (pressure). In a single-stage centrifugal fan, the gas enters the impeller in the axial direction, changes to the radial direction as it flows through the impeller, and then enters the diffuser. In the diffuser, the change in flow direction and the increase in cross-sectional area of the pipe decelerate the flow, which converts kinetic energy into pressure energy. This deceleration converts kinetic energy into pressure energy. The pressure increase occurs mainly in the impeller and to a lesser extent in the diffuser process. In multistage centrifugal fans, a return flow is used to move the gas flow to the next impeller, generating higher pressures.       Performance characteristics   The centrifugal fan is essentially a variable flow, constant pressure device. The theoretical pressure-flow curve of a centrifugal fan should be a straight line when the rotational speed is constant. Due to internal losses, the actual characteristic curve is curved. The pressure generated in a centrifugal fan is strongly influenced by changes in inlet air temperature or density. For a given intake air volume,^ the pressure generated at intake air temperature (air density^) ^ . For a given pressure versus flow characteristic curve, there is a power versus flow characteristic curve. When the blower is operated at a constant speed, for a given flow rate, the power required increases with decreasing inlet temperature.       Precautions   1、Emergency shutdown: In the process of test operation of the unit, in the event of one of the following circumstances, an emergency shutdown should be immediately. The operation of emergency shutdown is to press the main motor stop button, and then carry out the aftercare work after shutdown.   a. The centrifugal fan suddenly vibrates strongly and exceeds the tripping value.   b. There is scratching or abnormal friction sound inside the machine.   c. Smoke appears in any bearing or sealing place, or the temperature of a bearing rises sharply to the alarm value.   d. The oil pressure is lower than the alarm value and can not be restored to normal.   e. The oil tank level is low, and there is a phenomenon of suction emptying.   f. Shaft displacement value shows obvious continuous growth and reaches the alarm value.       2、Normal shutdown: The unit is shut down normally according to the following procedures.   a. Gradually open the bleeder valve (or outlet bypass valve), and gradually close the exhaust valve.   b. Gradually close the inlet throttle to 20～25°. c. Press the stop button.   c. Press the stop button and pay attention to whether there is any abnormality during the stopping process.   d. The oil supply can be stopped after the unit stops for 5～10min, or when the bearing temperature drops below 45℃. For the unit with floating ring seal, the sealing oil pump must continue to supply oil until the temperature of the body is below 80℃.   After the unit stops, the rotor should be periodically coiled 180° within 2~4 hours.       Installation matters   1, centrifugal fan installation of the whole unit, should be placed directly on the foundation with pairs of inclined pad iron leveling.   2、The centrifugal fan assembled on site, the cutting surface on the base should be properly protected, there should be no corrosion or operation, the base should be placed on the foundation with pairs of inclined pad iron leveling.   3、Bearing seat and base should be tightly jointed, longitudinal unevenness should not be more than 0.2/1000, measured with a level meter on the main shaft, horizontal uneven bottom should not be more than 0.3/1000, measured with a level meter on the level of the bearing seat in the middle of the surface.   4, Shaft tile research and scraping before the rotor axis line and casing axis line should be corrected, and at the same time adjust the clearance between the impeller and the air inlet and the spindle and the casing of the rear side plate shaft holes, so that it is in line with the provisions of the technical documents of the equipment.   5. When the main shaft and axial tile are assembled, they should be inspected according to the provisions of the technical documents of the equipment. An interference of 0.03 to 0.04 millimeters should be maintained between the bearing cap and the shaft tile (measure the outer diameter of the shaft tile and the inner diameter of the bearing housing).   6, fan casing assembly, the rotor axis line should be used as a reference to find the correct position of the casing and the impeller air inlet and casing air inlet between the axial and radial clearance between the high-speed to the scope of the equipment and technical documents, and at the same time, check whether the ground bolt is tight. The clearance value such as equipment technical documents do not specify, the general axial clearance should be 1/100 of the outer diameter of the impeller, radial clearance should be evenly distributed, the value should be 1.5/1000 ~ 3/1000 of the outer diameter of the impeller (outer diameter of the smaller take the larger value). Adjustment

The dust bag is the heart of the dust collector, and dust collector protection measures are done well to increase the service life of the dust bag! Long-term storage procedures are used to prevent damage and maintain operability of dust collector equipment received at the job site that cannot be installed immediately. Generally, equipment should be manufactured and shipped to match site preparation so that the dust collector can be installed directly upon reaching the site. However, there are many situations where the dust collector is purchased and manufactured, and transported to the owner's site, but there is no way to match the installation and plant downtime, and the availability of the engineering team for the installation does not fit with the plant downtime. This situation results in the dust collector being left on site for a month or even half a year. If this is the case, please follow the following procedure to protect the dust collector.       1. Cover the opening   The dust collector will be delivered to the site or plant with all openings completely sealed up and fastened together as tightly as possible. Typically, openings will be covered with plywood, plastic. If the dust collector needs to be moved, make sure that all these covers should remain intact. When storing the unit for placement, any unprotected openings should be plugged or covered to prevent rain, snow and other moisture from entering the interior of the dust collector. This can be accomplished with plastic wrap, plastic plugs, or wooden covers, depending on the size of the opening.       2. Store the equipment in a controlled environment   If possible, the dust collector enclosure, auxiliary components and accessories should be stored in a controlled environment with indoor temperature and humidity. For extended periods of storage (more than one month), place desiccant inside any electrical enclosures to prevent humid air from damaging electronic components. If adequate indoor storage space is not available, dust collector components, bags, bag cages, etc. should be stored indoors or in a dry, fully enclosed trailer or shed. Dust collector housings and larger components may be stored outdoors in a protective shed or supported on shelves and covered with a tarpaulin.       3. Other painted supports should also be protected   Structural steel supports, frame steelwork, handrails, and platform sections will be shipped as separate components as described in the unit bill of materials. All steel will be painted as specified in the contract. Paint will provide adequate surface protection over a period of time. As a general rule, all equipment is finished painted so it is resistant to metal erosion. However, materials such as support steel are usually stored on their sides and rain/snow/dirt may collect on horizontal surfaces. These can accelerate potential corrosion, particularly because of the extended contact time between the surface and moisture. If prolonged storage is required, support and access steel should be carefully stored and protected, especially during seasonal changes or severe inclement weather.       4. Remember to check regularly   All equipment stored outdoors should be inspected periodically to monitor the integrity of the equipment and the condition of painted surfaces. Any cracks in the covering should be repaired immediately. Dust collectors, auxiliary equipment, or any areas on supporting steel members that collect water or debris should be braced to minimize the possibility of future problems. These areas can be supported with wood, other steel members, etc. Like a camping tent, there are poles or beams that secure a center to keep rainwater from running off the top to ^ where it may eventually leak inside.       5. Accessory protection   (1) Rotary airlock valve   Remember that the inside surface of the rotary valve is not coated. Before storage, spray the inside of the valve with a rust and corrosion resistant oil. Also, provide and install metal covers for the inlet and outlet flanges with at least four capscrews per flange. Keep these covers in place until you are ready to use the valve. Next, completely fill the worm gear reducer with a worm gear and replace the vented fill plug with a sturdy plug. Be sure to keep the vented plug for future use. Then, read and follow the motor, gearhead and other equipment manufacturer's instructions for long-term storage. After completing the above steps, plug in all wire box openings on the motor and switch and store the valve from the floor in a dry, well-ventilated indoor area without ^temperature changes. Turn the rotor several times every six months, placing the rotor in a different angular position after each turn.       (2) Screw conveyors   The inside surfaces of screw conveyors are usually uncoated. Prior to storage, spray the inside of the troughs and tighten them with the rust-proof antirust oil used on rotary airlock valves. Again provide and install metal or wooden covers for the inlet and outlet flanges. Ensure that the covers are properly secured to provide adequate protection for the internal components. Completely fill the worm gear reducer with oil and replace the vented filler plug with a strong plug. Retain the vented plug for future use. Then, read and follow the motor, gearhead and other equipment manufacturer's instructions for long-term

Water film dust collector is a kind of dust collector product which relies on the role of powerful centrifugal force to throw the dust particles in the smoke and dust to the water film wall, and then be washed away by the water flowing down from the side wall, so as to get rid of the dust particles.       The following is an introduction to the use of water film dust collector in the process of common failures and ways to deal with them:       First, the dust collector spray water film formation is not complete, dust removal effect is poor   1. Check whether the circulating pump is faulty, whether the feed water pressure is normal, if it is the reason of pump body, overhaul or replace the pump body.   2. Check whether the pipes and valves are corroded and leaking or clogged, resulting in insufficient water pressure; if there is any problem, repair or unblock the pipes and valves in time, and replace the valves if necessary.       Second, flue gas with water   1. The water level in the dust collector is too high, resulting in flue gas with water. Reduce the water level in the dust collector and prohibit the circulating water from flowing out of the overflow port above. 2. Granite water film dust collector flue gas with water drip catcher inside the wall of the stone seams have been worn by the flue gas, resulting in the exposure of the stone seams into a step-like, from the top to the bottom of the water film flow through the place, collision steps splash water droplets, resulting in flue gas with water.       Third, the water film dust collector dust removal effect is poor, resulting in large vibration of the induced draft fan   1. When the water droplets with dust are brought to the impeller of the induced draft fan by the running flue gas, they adhere to the impeller, causing the impeller to lose balance and causing vibration. To regularly clean up the impeller accumulated dust, each time the shutdown should open the fan manhole to check and clean up, so as not to cause fan vibration. In addition, overhaul the dust collector to reduce the flue gas with water and dust. 2. The dust removal effect is not good, the flue gas contains too much dust, resulting in uneven wear on the fan impeller resulting in impeller imbalance and cause vibration. Counterweight the fan impeller, so that the impeller to restore balance, if necessary, replace the impeller. At the same time, overhaul the dust collector to reduce the content of dust in the flue gas.       Fourth, no water out of the dust collector drainage port   1. Check whether the book pump is running normally, check whether the absorption port of the pump is blocked by impurities, such as pump problems, timely maintenance or switch to another pump operation, if necessary, replace the pump. 2. Check whether the water level in the sedimentation tank is normal, if the water level is too low, replenish the circulating water in time. 3. Check whether the drainage port of the water pump is blocked by the lining rubber or impurities shed in the dust collector, and clean out the blockage in time. 4. Drain valve stem and spool off, drain boring blocked by the spool, replace the drain valve in time.       Fifth, the water film dust collector dust pump vibration powerful solutions   1, bolts, check the fixed pump bolts are not loose, if loose, appropriate reinforcement. 2, motor bearings, check the motor bearings have no lubricant, if not, appropriate lubrication. 3, pump bearings, check the pump bearings are not worn, if worn, replace with a new one. 4, concentric, check the motor and pump chain shaft is not concentric, if not concentric, appropriate adjustment. 5, connecting cushion, check the chain shaft with the connecting cushion is not badly worn, if worn, replace with a new one.       Sixth, cause the water film dust collector dust removal efficiency low reason   1, water film blank: the inner wall of the formation of the water film is incomplete, there is no water film blank, the treatment of dust is not complete. 2, unstable airflow: the gas flow in the water film dust collector is too fast, resulting in unstable airflow, dust is blown away directly, and when the speed is too fast, the water film will also be drawn away. 3, small centrifugal force: gas in the water film dust collector into the speed is too small will lead to insufficient centrifugal force, dust can not be fully contact with the inner wall of the water film.

    Related to the waste emission standards and how the enterprise on the chimney specification design Many enterprises of the chimney in the design and construction of the chimney, may not pay much attention to the industry emission standards, resulting in ^ after the exhaust setup can not meet the environmental protection standards. Today collected with each waste gas exhaust related to emission standards, how enterprises on the chimney specification design, I hope to help the construction unit.       First, not in accordance with the provisions of the air pollutant emissions outlet set up   The height of the exhaust is not enough; not set up monitoring and other sampling holes, sampling platforms, as well as emission signage, the focus of environmental protection inspections and law enforcement.       Second, the exhaust gas chimney (exhaust) specifications: general provisions of the design   1.
