Abstract

A drying machine comprises a cavity, a vacuum system, a heating system, a condensation system, a material carrying system and a control system, wherein the vacuum system, the heating system, the condensation system, the material carrying system and the control system are arranged in the cavity, and the control system controls operation of the vacuum system, the heating system, the condensation system and the material carrying system. The cavity comprises a vacuum pre-cooling drying bin, a far infrared drying bin and a microwave drying bin. The cavity is provided with a first isolation valve, a second isolation valve, a third isolation valve and a fourth isolation valve. The front end of the vacuum pre-cooling drying bin is connected with the outside of the bin through the first isolation valve, and the rear end of the vacuum pre-cooling drying bin is connected with the far infrared drying bin through the second isolation valve. The front end of the far infrared drying bin is connected with the vacuum pre-cooling drying bin through the second isolation valve, and the rear end of the far infrared drying bin is connected with the microwave drying bin through the third isolation valve. The front end of the microwave drying bin is connected with the far infrared drying bin through the third isolation valve, and the rear end of the microwave drying bin is connected with the outside of the bin through the fourth isolation valve. The control system controls opening and closing of the first isolation valve, the second isolation valve, the third isolation valve and the fourth isolation valve.

Description

technical field [0001] The invention relates to a drying machine, in particular to a continuous microwave vacuum ice-temperature drying machine. Background technique [0002] Ice temperature drying technology is a new food drying method born from the application of ice temperature storage theory to the field of food drying. In the traditional low-temperature storage of food, storage above 0°C and below 10°C is called refrigeration, and below 0°C is called freezing. The freezing point of food, also known as the freezing point, is lower than 0°C. When the temperature is lower than 0°C and higher than the freezing point, the food cells are always in a living state. The inventor of ice temperature technology, Dr. Yamane Akimi from Japan, defines the area below 0°C and above the freezing point as the "ice temperature zone" of the food. Preserving food in this temperature zone can not only effectively reduce the energy consumption of refrigeration equipment, but also Overcome th...
