Food Freeze Dryer

      Compared with the usual drying methods such as sun drying, oven drying, spray drying etc., the freeze drying has the following advantages:

1.     Proteins don't denature，microorganisms maintain their biological activity.

2.     Almost no loss of volatile substances, heat-denatured nutrients and aroma components in the product.

3.     The growth of microorganisms and the action of enzymes can hardly be carried out and the product can best maintain its original properties.

4.     After freeze-drying, the volume and shape of the product are almost unchanged, and the rehydration is good.

5.     Freeze-dried under vacuum with very little oxygen, so that easily oxidized material is protected.

6.     Freeze drying can remove95-99.5% of the moisture in the material, and the storage period of the product is longer.

      Food  Freeze Dryer Features:

1.     The pre-freezing chamber and the freeze-drying chamber are separate structures, they work at the same time, which improves the freeze-drying efficiency and shortens the freeze-drying time.

2.     The Shelf made of aerospace grade aluminum alloy is used for double-sided radiation heating, and the radiation rate is more than 90% to ensure good temperature uniformity..

3.     High efficiency mixed refrigerant medium: low freezing point and high boiling point to ensure high heat transfer efficiency and long service life.

4.     The drying curve optimization control algorithm can control the heating rate and vacuum degree value of products in the drying stage.

5.     The patented gas diversion technology ensures that the condenser has strong ice catching ability and high drying efficiency.

6.     Flexible manual and automatic control mode, manual mode is used for testing production process, automatic mode is used for mass production.

7.     Accurate sensor calibration function ensures the accuracy of process parameters for long-term use.

8.     The user’s level and password can be set for decentralized operation management.

9.     Can be customized according to user needs.
