HXD series food freezing dryer is developed by our company together with some national research institutions, with customized models, top technology, high configurations to make perfect conbination of aseptic technique and freezing drying technique. It can be maximum applied in big scale production and solve confliting between output and selling in agricultural peak period, also advance original ecology storage technology for agriculture products and increase both production and income.

Vacuum freezing dryer is composed of vacuum drying system, refrigeration system, heating system, heating plates, gauges and control system, etc. Suitable for freezing drying process of aquatic products, vegetables & fruits, meat, mushrooms, etc.

Application:

Drying for biology technology, aquatic products, grain, fruits, foods, milk, medicine, etc. It is suitable for produts which sensitive about temprature, easy get bad, but needing its original taste kept and no destroy on structure.

Basic Principle:

Four basic conditions during freezing drying process:

1. Surface temperature of cold trap lower than -35℃

2. Product is below freezing point.

3. Vacuum degre ⩽40Pa

4. Production temperature is controlled between -40℃~+60℃ with sublimation potention heat, and products not melt above eutectic point.

Dryig Process：

a. Pre-freezing; b. Initial drying; c. Main drying; d. reduce drying; e. ultimate drying.

Basic Parameters:

Remarks:

a. Product water rate in best economical principle is between 60~90%, tray loading thickness at 10~15mm.

b. Pre-freezing can be in machine or cold room;

c. Heating plate must control product temperature at 5~10℃ below eutectic point during main drying period and no melting, maximize temperature difference with cold      trap to speed up drying rate.

d. Heating plate temperature in ultimate drying stage would be product highest temperature without spoilage.
