Abstract

The invention relates to a vacuum microwave dehydration device, which belongs to the technical field of food processing and drying treatment. It mainly installs a rotating tray in the center of the lower part of the base of the negative pressure sealing chamber. The rotating shaft of the rotating tray is connected with the rotating device. The interface, the waveguide interface is connected with the microwave waveguide, the microwave waveguide is connected with the microwave generator, the vacuum pump is connected with the vacuum buffer tank, the vacuum buffer tank is connected with the base of the sealed chamber through a pipeline, and the water vapor observation glass tube is connected into the pipeline. The invention has a simple, compact and reasonable structure; it can ensure that the food is quickly dehydrated and dried below 60°C, and the chlorophyll, vitamins, and various amino acids can better retain their original colors; The original flavor can be fully retained; the manufacturing cost is low, flexible and convenient, easy to operate, and can realize large-scale production.

Description

technical field [0001] The invention relates to a vacuum microwave dehydration device, which belongs to the technical field of food processing and drying treatment. Background technique [0002] Fresh vegetables, Chinese herbal medicines, edible fungi, etc. have a high water content and cannot be stored for a long time. They often need to be dried or dried in the sun to be dehydrated. Before the present invention is made, in prior art, the method for drying mainly adopts heating drying dehydration and freezing vacuum dehydration at present. The former heating and drying method is in the dehydration process, the temperature is often higher, or the time is longer. In the process of heating and drying in the air, some active ingredients are oxidized at high temperature, some active ingredients are decomposed, and some are decomposed. The active ingredients are killed, and many vitamins and amino acids are decomposed. After rehydration, it is difficult to restore the original f...
