The freeze dryer we provide is for food, herbals, pharmaceutical and chemicals. We have two types freeze dryer available: 
1, contacting type: for small scale production, no IQF(individual quick freezer), no tracking system. freeze material on the plates. 
2, radiant type: for middle and large producton. equiped with IQF, tracking system. freeze material in IQF, heat material in the plates. 

Radiant type is more cost-effective, save energy, save drying time. The material needs to be pre-frozen till material completely frozen. It needs about 3-4 hours. The frozen material will be put on our product trays (supply two groups, one for production, the other for next batch preparation). The product trays with material will be placed on trolley that hanging on the tracking system for movement. The rails will go through raw material preparing area, IQF, in side the lyophilizer, product unloading area. So, you can push the material with big quantity, no need manual carrying.

We provide refrigeration compressors system for freeze vapour condenser. We provide vacuum pumps, roots pumps for vacuumizing the vessel. We provide heating exchange system for heating (by electricity or steam). The defrost is after a batch of production. It just needs 1-2 hours. You can use room temperature water to defrost or by hot water recycled from the thermal from refrigeration compressors to shorten defrost time to 30 minutes. All systems are control by central PLC. The system is simple.
