Application of GuanFeng Vacuum Freeze Drying Machine

Vacuum Freeze Dryer is an advanced Hi-Tech dehydration technology. It makes hydrous material 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 use 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 Dryer technology has widely application, such as for chemical products, biologics, health product, herbs, agricultural products ( meat, poulty, egg, sea food, vegetables and fruits etc. ).

Technical Strength of GuanFeng Vacuum Freeze Dryer

GFD series vacuum freeze dryer mainly includes: material quick freezing system, vacuum tank system, heating system, vacuum system, refrigeration system, material transfer system, electric control system, pneumatic system, disinfection system.

The vacuum system apply water ring pump or oil seal pump with multi-stage roots pump combination. In the beginning, it uses oil seal pump with large power to remove air out quickly. And then, it uses roots pump to keep the vacuum condition with small power. In this way, it can decrease the energy consumption. Meanwhile, the water ring pump can remove the water content, which can avoid the disadvantage of oil seal pump of poor drainage performance, moisture making oil emulsfication metamorphism and vacuum instability.

Heating system is sealed water circulation system with automatic compression function. It applies 3-way regulated valve to adjust the heat of water circulation system. The automatic compression system can gurarantee hot water temperature to +120*C, which increase the thermal efficiency.

Refrigeration system applies Freon refrigeration for samll middle model. The expansion valve adjusts liquid flow automatically. For large model, it applies ammonia Single-phase circulation refrigeration, the refrigeration liquid supply is stable and easy for operation. The Ice-Condenser apply postposition type cold trap. The pipes connection is short, little resistance. Moisture and gas access is smooth. The water catch is evenly, efficient and engergy saving.
