Chinese medicine extract is a paste-like Chinese medicine produced by extracting and concentrating Chinese medicinal materials. Generally, it must be prepared into Chinese medicine extract dry powder before the next step of preparation.
General Chinese medicine extract contains monosaccharides or polysaccharides, as well as a large amount of starch and amino acids, so Chinese medicine extract has the characteristics of easy hygroscopicity, easy coking, and low softening point.



In recent years, the market size of Chinese medicine extract industry has maintained a steady growth trend. The development of my country's economic level and the growth of consumption level, as well as the growth of upstream and downstream industries and related industries, have promoted the continuous increase in the demand of domestic Chinese medicine extract industry.


In view of the characteristics of Chinese medicine extract that is easy to absorb moisture, easy to coke, and has a low softening point, Zhiheng has developed the MVD series low-temperature pulsating vacuum drying oven.
The equipment operates under vacuum conditions and can be widely used in material drying in various industries, especially for heat-sensitive materials or materials with strict temperature requirements and high viscosity. The equipment adopts the principle of pulse and laminar vacuum drying, which is an efficient low-temperature drying method. Especially for extracts with high sugar content, low temperature, easy overflow and easy foaming, the drying effect is very good.





Mild drying temperature and good uniformity
Chinese herbal medicine extracts have high requirements for drying temperature control and are prone to coking.
Our vacuum drying oven has a mild drying temperature, which can strictly control the temperature of the material within a certain range; at the same time, the drying uniformity is good, and the material can be effectively dried into powder with uniform batches.

Using pulse and laminar flow technology, high drying efficiency
Our vacuum drying oven uses pulse and laminar flow technology to quickly strip the moisture from the wet material, achieve rapid drying, improve drying efficiency, and reduce wall sticking. The equipment has a high degree of automation and good product quality, while also reducing the floor space.

High vacuum degree and uniform batches
Our equipment has a high vacuum degree, which can strictly guarantee the freshness of perishable materials such as Chinese herbal medicine extracts. The dried materials have uniform batches, uniform powder, good color, and are not easy to deteriorate, which can greatly improve the economic benefits of the factory.

The inner cavity is smooth without dead corners, and the drying rack can be removed
Food materials such as Chinese herbal extracts require a clean and dry environment. The inner cavity of our vacuum drying oven is smooth without dead corners, which is easy to clean. The drying rack can also be removed to avoid cross contamination of materials and meet GMP production requirements. At the same time, our equipment can also be equipped with an online cleaner to make cleaning easier.
