The powder granule in fluid bed appears in the state of fluidization. It is preheated and mixed with clean and heated air. At the same time the solution of adhesive is sprayed into the container. It makes the particles become granulating that contains adhesive. Being of unceasing dry through hot air, the moisture in the granulating is evaporated. The process is carried out continuously. Finally it forms ideal, uniform and porous granules.

It’s applied for drying and dehumidification of material in such trades as pharmaceutical, chemical foodstuff, light industry, heavy industry etc., as well as heating and dehumidification of product, including raw medicines, original medicines, doses, traditional Chinese medicine tablet, powder, granulate, electuary, ball packing bottle, pigment, dyestuff, dried vegetable, food, plastic resin, electric clement and baking finish etc.

The Dry case is designed according to vacuum vessel of international standard. Case shape is horizontal cylinder. Exterior has multitasked stiffener to strengthen. Test the vacuum air impermeability after welding. Silicone rubber is used to seal between the drying case and the case door. Sight glass with light is set on the door. Hanger rail is set on the drying case to take the products get in and out.

Vacuum Freeze Dryer is an advanced Hi-Tech dehydration technology, It makes hydrous materials frozen in the low temperature status, then under the vacuum condition, it adopts thermal radiation method for heating, to sublimate ice to gas directly. After the moisture comes out, it uses ice-condenser (cold trap) and vacuum device to dehydrate the water content. It is a combined application technology based on multidisciplinary development, including refrigeration, heating, vacuum, biological, electrical and etc. Vacuum freeze drying technology has widely application, such as for chemical products, biologics, health product, herbs, agricultural products ( meat, poulty, egg, sea food, vegetables and fruits and etc.)
