Freeze-drying is a technique for drying by the principle of sublimation, which is to quickly freeze the dried material at low temperature. Then the frozen water molecules are directly sublimated into a process of water vapor evolution in a proper vacuum environment. The product of this process is called Freeze-dried product.

Product Features

1.Dry chamber door and cold well door adopt aviation acrylic materials with high strength and no leakage.

2.Seven-inch true color industrial touch screen has high control precision, stable performance, and is easy to operate.

3.Internationally famous brand compressors are efficient in energy and more stable.

4.Inflate valve, drain valve and high vacuum safety diaphragm valve can be connected with inert gas, which can extend material shelf life.

5.Manual, automatic model for choice, manual mode for exploring the process; automatic mode for mature technology, one button operating.

6.Monitoring screen; real-time monitoring of plate temperature, cold trap temperature, vacuum and other operating conditions.

7.Data record mode, data record multiple selection, data export and other functions.

8.Two temperature control modes can be switched at any time; standard temperature rise and fall mode, with smooth temperature control mode.

9.Freeze-drying curve query function, so you can view the temperature, vacuum and other curves at any time.

10.Set user level and permissions password, so users can enter into the manager system based on the permissions.

11.This machine can store 40 sets of freeze-drying process, each set can set 36 segments.

12.The machine use 36V electric defrost, compare with non-electric defrost, the speed is faster and the safety grade is higher.
