Dry food is a necessary measure to improve food storage and quality. The performance of vacuum dryer directly affects the quality and value of food. In recent years, although China's food drying industry has developed a variety of multi-functional, high-efficiency, low-energy, adaptable vacuum dryers, the vacuum dryer has a domestic market share of more than 80%. Vacuum dryer companies are concentrated. Mainly distributed in Jiangsu, Zhejiang, Shanghai, Liaoning, and Black. Enterprises in these regions account for almost 50% of the total industry.
Domestic vacuum dryers have obvious price advantages in the market competition than imported equipment; on the other hand, due to the large volume of drying equipment, most of them also involve on-site installation, commissioning and after-sales service, so for domestic users, It is more convenient to use domestic equipment than to use imported equipment. The heated plate in the vacuum drying cabinet is divided into several layers. Hot water or low-pressure steam is used as a heating medium in the heating plate, and the tray on which the medicine to be dried is placed is placed on the heating plate, the door is closed, and the vacuum is pumped in the box. The heating plate heats the drug to a specified temperature in the circulating flow of the heating medium, and the moisture begins to evaporate and is gradually withdrawn by vacuuming. The device is easy to control, can condense and recover the evaporated solvent, and the drug is not easily contaminated during the drying process, and can be used for drying the drug, packaging sterilization and heat treatment.
 Designed for drying heat-sensitive, easily decomposable and easily oxidizable materials, the vacuum dryer is capable of flushing inert gases into the interior, especially for complex parts.
