Vacuum Freeze Dryer/Drying Fruit Tray Machine China

Introduction

Microwave vacuum drying technology combines the advantages of microwave technology and vacuum technology, and is extremely beneficial for the drying of heat sensitive materials. Compared with the conventional drying method, it has the characteristics of low energy consumption, short drying time, low working temperature, good product color and high vitamin preservation rate. It is suitable for low-temperature drying sterilization and low-temperature concentration of heat-sensitive, easily oxidizable, high-viscosity, high-concentration liquid materials in medicine, chemical, food, biological products, agricultural and sideline products, such as: Chinese herbal extract, ginseng, donkey-hide gelatin, antler, Vegetables, flowers, biochemical products, health products, additives, etc.

Working principle
The working principle of the hot air dryer is to use the inverse Carnot principle, the refrigerant is compressed by the compressor, and becomes a high temperature and high pressure gas. The gas temperature can reach 100-110 °C, and the high temperature gas passes through the pipeline (copper pipe). Entering the heat exchanger (condenser), and then passing the fan, sending the heat generated by the heat exchanger (condenser) to the drying room to heat and dry the material, and evaporating the heated material in the drying room The dehumidifier is dehumidified or the dehumidifier is discharged to the drying room to achieve the purpose of drying.
