Chinese medicine extract spray dryer
Characteristics of Chinese medicine extract spray dryer
Traditional Chinese medicine extract spray dryer is a fog dryer specially designed and manufactured by Changzhou Lima Drying Engineering Co., Ltd. for the high sugar content of traditional Chinese medicine extracts . Combining the most advanced spray drying technology of the same kind in foreign countries and the long-term practical experience accumulated by our company's technicians, we have achieved the following points in the design process of traditional Chinese medicine extract spray drying :
1. Specially designed volute and hot air distributor: In order to avoid the phenomenon of “vortex pumping” caused by the high-speed rotating atomizing disk, which results in “fog droplets returning to the top or powder suction”, a specially designed spray drying main tower (Rapid advance structure) The hot air volute and hot air distributor ensure that the atomized droplets of the material do not return to the top, and the air cooling technology is used to prevent the material from returning to the top and melting and coking.
2. Freezing, dehumidifying, wind-feeding, and cooling-receiving device: This technology can quickly leave the material in the high-temperature area and cool it, avoiding the phenomenon of softening and agglomeration of the material caused by the material staying in the high-temperature area of the cyclone for a long time. It avoids the phenomenon of hygroscopic material and agglomeration.
3. Traditional Chinese medicine extract spray drying tower wall rotary purge device: It is specially designed for the characteristics of Chinese medicine extract materials with high sugar content and high temperature and easy to soften sticky walls, effectively solving the phenomenon of sticking walls of traditional Chinese medicine extract materials and avoiding materials. The problem of material deterioration caused by staying at the tower wall for a long time can not even produce when sticking to the wall seriously.
The traditional Chinese medicine extract spray dryer has been improved in the design:
1. All the contact points with the materials in the spray drying machine of the traditional Chinese medicine extract adopt flat or circular transitions, and the contact surfaces are polished and polished (fine polishing to more than 10) to avoid trachoma and dead corners. Prevent material accumulation and blockage; the whole unit is made of stainless steel at the point of contact with the material to ensure that the material is not contaminated; the transmission parts in contact with the material are well sealed to prevent water and oil; the sealed area is operated with a butterfly valve to prevent air leakage; The air discharge pipe section adopts live connection, which can be disassembled, cleaned, disinfected, sterilized, etc. at any time;
2. The diameter and height of the traditional Chinese medicine extract spray drying tower have been adjusted accordingly, to ensure that the material cannot reach the tower wall before drying, and to ensure that the material stays in the hot air; the jacket is equipped with a jacket cold air cooling device to ensure the material Softened, melted or even coked due to the local temperature being too high on the tower wall. The cone angle increased, and air cones were installed on the cone. The compressed air pulsed earthquake was used to strike the cylinder. The powder was shot down smoothly;
3. The air pre-treatment system adopts junior high and high three-level air filtration to purify air to 100,000 levels;
4. PLC program control system circuit for traditional Chinese medicine extract spray dryer ; touch screen animation shows the process flow, has operability, variable operation parameters realize fuzzy technology automatic tracking adjustment; use the inverter to adjust the atomizer stably and safely; in and out Digital display of wind temperature and pressure in the tower, precise setting, etc.
