overview
ZDJ type vacuum belt dryer for traditional Chinese medicine extracts is a new type of special dryer developed by our company in recent years. This machine solves a major problem for alcohol extracted traditional Chinese medicine extracts with high concentration and high viscosity. In the past, centrifugal spray was used. Due to high temperature, the thermosensitive components were damaged and easy to stick to the wall; The use of a vacuum oven cannot achieve continuous production due to its long time, high energy consumption, susceptibility to bacterial contamination, and tendency to regain moisture, all of which fail to meet GMP quality standards.
This machine has overcome many problems mentioned above, such as low drying temperature, no loss of effective ingredients, short drying time, low energy consumption, no pollution, continuous production, and automatic control, which can effectively ensure product quality and fully comply with GMP requirements. It is an efficient, energy-saving, and new type of drying unit.
This machine is not only suitable for drying traditional Chinese medicine extracts, but also for drying various products such as polysaccharide drugs, biopharmaceuticals, coffee, etc., with a wide range of application prospects.

Working principle
Under high vacuum conditions, the material is continuously and uniformly coated on the moving track by the fabric machine, forming a thin layer of material film. The track enters the heating section for low-temperature heating, and the gas phase temperature is generally controlled below 50 ° C℃The moisture in the material is quickly removed by vacuum evaporation through bubbling; The material enters the cooling section and is rapidly cooled by ice water to make it brittle. The material is then collected by a scraper and automatically controlled to be discharged. The resulting product is a natural and crispy granule with a continuous automated production process, making it an ideal equipment for the production of traditional Chinese medicine extracts.

characteristic
1. The entire drying process is completed in a high vacuum state, which complies with the quality management standards of pharmaceutical production GMP;
2. The unit is heated in three zones. Zone 1 is heated directly with steam, while zones 2 and 3 are heated with hot water at a temperature below 50 ° C℃Invariance of thermosensitive materials;
3. High vacuum is achieved by the vacuum original unit;
4. Quantitative constant speed feeding with screw pump, which can be set according to physical properties;
5. The track runs smoothly and reliably, with adjustable speed and made of stainless steel material;
6. Continuous discharge under vacuum state, replace the material bucket;
7. Low energy consumption, no three wastes, low noise;
8. Can automatically control the operating system; PLC programmable, touch screen operation;
9. The track adopts five layers, each layer is heated by a plate heat exchanger;
10. The discharge port has crushing and granulation functions, and the particle size can be set by the user;
11. The unit is equipped with a high-pressure water cleaning system with CIP function, which meets the requirements of easy cleaning.
