Industrial Low Temperature Vacuum Tray Dryer

Introduction of Industrial Low Temperature Vacuum Tray Dryer

This square vacuum drying machine is to use electric or steam or hot water or heat transfer oil as heat sources, use radiator to generate heat. Water vaporizes very fast when it’s boiled. Under ordinary pressure, water starts to boil at about 100℃, but under vacuum condition, vaporization occurs when it is below 100℃. For example, water starts to boil at only 70℃ when its surface pressure is -0.07Mpa. WKS series square vacuum drying machine is highly efficient under low temperature condition. It is suitable for drying materials like pharmaceuticals, chemicals, foods, heavy and light industry products, thermally sensitive material too.

Application of Industrial Low Temperature Vacuum Tray Dryer
Widely used for heating, solidification and dehydration of pharmacy, chemical, food, light industry, heavy industry materials and products, such as raw material medicine, medicine, Chinese Herbal Medicine, powders, granules, pill bottles, pigments, dyes, dehydrated vegetables, dried fruit, sausages, plastic resin, electric elements, drying varnish and so on.

Working Principle of Industrial Low Temperature Vacuum Tray Dryer

Vacuum drying is a process in which materials are dried in a lower pressure environment, which reduces the heat needed for rapid drying. Drying machines used for this process are known as vacuum drying machine, and vary in size from small units designed to fit on kitchen counters to massive rooms which are used to handle things like timber products.

Drying involves reducing the moisture in an object, and is done in environments where the air is drier than the object being dried, which encourages moisture to evaporate out. This is often accomplished with heat to reduce the humidity of the air, but in a vacuum drier, the temperature does not need to be as high, and the drying is often faster. It’s also possible to achieve a very high level of dryness, which may be desirable in some cases.
Features of Industrial Low Temperature Vacuum Tray Dryer
◎The boiling point of the material solution is reduced under vacuum. Increase the heat transfer driving force of the evaporator. Therefore, the right heat transfer can save the heat transfer area of the evaporator.
◎The heat source for evaporation operation can be low pressure steam or waste heat steam.
◎The evaporator has less heat loss.
◎Disinfection treatment can be carried out before drying, and there is no impurities in the drying process, which meets the requirements.
◎It is a static vacuum dryer. Therefore, the shape of the dried material will not be damaged.
