Distributed radio frequency or microwave thawing equipment

Abstract

The invention provides distributed radio frequency or microwave thawing equipment. The equipment comprises one or more thawing units. The thawing unit comprises a power supply module, a control unit,a radio frequency or microwave generation module, a measurement unit, an antenna device and a thawing cavity. The antenna device is arranged in the thawing cavity, and comprises a first antenna groupand a second antenna group. The first antenna group and the second antenna group respectively comprise one or more first antennas and one or more second antennas, the first antennas and the second antennas are arranged in pairs, each first antenna and the corresponding second antenna which are arranged in pair are parallel to each other and are oppositely arranged to form an antenna unit, and theantenna units are arranged side by side. The number of the radio frequency or microwave generation modules and the number of the measurement units are one or more. The radio frequency or microwave generation module and the measurement unit are connected with the antenna units in a one-to-one correspondence manner. According to the thawing unit, radio frequency or microwave energy is provided for one or more antenna units by the independent radio frequency or microwave generation modules, so that the problem of energy loss caused by power combination is avoided.

Description

technical field [0001] The invention relates to the technical field of thawing, in particular to a distributed radio frequency or microwave thawing device. Background technique [0002] Radio frequency or microwave thawing is a new type of thawing method, which uses high-speed changing radio frequency or microwave oscillating electromagnetic fields to heat up the crystal lattice, molecules, ions, etc. in the item to be thawed by violent vibration, rotation, etc. . Compared with other thawing methods, the speed of radio frequency or microwave thawing is faster, the heating is uniform, and the quality of the items to be thawed is less affected. [0003] The Chinese patent document with the publication number CN208768875U discloses a radio frequency thawing device, including a housing, and the interior of the housing is divided into a radio frequency space and an accommodation space from top to bottom by a partition; There is an air inlet, and the top of the radio frequency s...

AI Technical Summary

Problems solved by technology

The radio frequency thawing device provided by this solution only places a pair of antennas in the radio frequency space. When the equipment needs to use high power, the power loss will increase accordingly. And with a pair of antennas, the power density at different positions on the antenna board is different. , the power density away from the power-on position is small, and there is a problem of uneven power density
