Vacuum microwave dehydration equipment and method

Abstract

The invention discloses vacuum microwave dehydration equipment and method. The vacuum microwave dehydration equipment comprises a microwave box body, a vacuum cavity formed inside the microwave box body, and a microwave source, wherein the microwave source emits microwaves into the microwave box body through a microwave inlet formed in the wall of the microwave box body; and the vacuum microwave dehydration equipment further comprises a rotary disc connected with the vacuum cavity, and when the microwave source emits the microwaves into the microwave box body, the rotary disc drives the vacuumcavity to rotate inside the microwave box body. According to the equipment and the method, the uniform and consistent dehydration effect of the materials can be achieved; and meanwhile, semi-continuous or continuous dehydration production can further be carried out to adapt the requirements of commercial large-scale production and improve the automation level.

Description

technical field [0001] The invention relates to the technical field of microwave dehydration, in particular to a vacuum microwave dehydration device and method. Background technique [0002] Microwave dehydration technology has a history of more than 40 years. In recent years, it has been widely used in the food and pharmaceutical industries. Its low-temperature and rapid dehydration features have received more and more attention in various fields. [0003] In recent years, vacuum microwave dehydration technology has developed relatively rapidly to meet people's demand for higher product quality and large-scale commercialization. Especially in the application of agricultural products, food and medicine, the technology is becoming more and more mature. Since the boiling point of water decreases as the pressure decreases, properly applying microwave energy under vacuum conditions can dehydrate the water-containing material at a lower temperature to avoid the change of propert...

AI Technical Summary

Problems solved by technology

However, it is difficult to carry out large-scale dehydration production in this way

Using a larger vacuum chamber and using multiple rollers at the same time can increase the output of a single production, but the size and complexity of the production equipment and the difficulty of operation will greatly increase, and this method cannot achieve continuous production
