Food drying is the necessary measures to improve food storage, quality, performance of vacuum dryer directly affects the quality and value of food. In recent years, drying of food industry in China has developed a variety of multi function, high efficiency, low energy consumption, strong adaptability of vacuum dryer, vacuum dryer in the domestic market share has reached more than 80%. Vacuum dryer enterprises concentrated distribution. Mainly distributed in Jiangsu, Zhejiang, Shanghai, Liao, black, this in several areas of the enterprises accounted for almost 50% of the total number of whole industry,
Vacuum dryer made with obvious price advantage in the market competition than imported equipment; on the other hand, due to the drying equipment volume is larger, most also relates to the site installation, commissioning and after sale service work, so the domestic user, the selection of home-made equipment than imported equipment more convenient. Vacuum drying box is heated plate is divided into a plurality of layers. The heating plate in hot water or steam as the heating medium, tray will spread to be dried drug on the heating plate, close the box door, the box with vacuum pumped by a vacuum pump. The heating plate in the heating cycle, drug flow of heating medium to the specified temperature, water evaporates and with vacuum pumping draining. This device is easy to control, condensing the evaporated solvent recovery, drying process of medicine can not be polluted, can be used in drug package material drying, sterilization and heat treatment.
Vacuum dryer for drying heat sensitive, and the design is easy to decompose and easily oxidized substances, can get into the inert gas to the inside, especially some complex objects can be fast drying. |
