Introduction to Vacuum Freeze Drying Machine:

A vacuum freeze dryer is a device that converts liquid or semi-solid substances into dried products through freezing and vacuum drying techniques.

1、 The principle of vacuum freeze dryer

The drying principle of a vacuum freeze dryer is to evaporate water from liquid or semi-solid substances in a frozen state through a vacuum drying process, and transform the substances into dried products. This process mainly involves three key factors: freezing, vacuum, and heating. The purpose of freezing is to freeze the substance and keep it in a low temperature state; The purpose of vacuum is to extract the air around a substance and create a vacuum state; The purpose of heating is to raise the temperature of a substance through a heater, causing water to evaporate.

2、 Structure of Vacuum Freeze Drying Machine

The vacuum freeze-drying machine is mainly composed of cooling system, vacuum system, heating system, temperature control system, electrical control system and other parts. Among them, the cooling system mainly consists of a freezer, a condenser, and other parts, which freeze substances; The vacuum system mainly consists of vacuum pumps, adsorption tanks, and other parts, which extract the air around the material; The heating system mainly consists of a heater, a heating plate, and other parts, which raise the temperature of the material; The temperature control system monitors and controls the temperature of substances through temperature sensors; The electrical control system adjusts and controls various parts through a controller.

3、 Application of Vacuum Freeze Drying Machine

Vacuum freeze-drying machines are widely used in industries such as food, biological products, pharmaceuticals, and chemicals. In the food industry, vacuum freeze-drying machines are used to produce various dried fruits, vegetables, meats, and other dried foods, as well as beverages such as coffee and tea.
