Problems solved by technology

The pyramid antenna is fed sideways, and the microwave cannot directly irradiate the upper and lower surfaces of the material, so the efficiency is low
Moreover, the feed energy of the pyramid antenna is relatively concentrated, which may easily cause excessive energy density in some areas and affect the thawing effect.
The power distribution of the power divider can only be divided into two according to a fixed ratio. If the power distribution of multiple ports is difficult to realize, or the structure is too complicated, the equipment loss will be large

Abstract

A microwave thawing device comprises a heating box, a first waveguide, a second waveguide, a plurality of first slot antennas, a plurality of second slot antennas and a microwave generator, a plurality of first coupling windows corresponding to the first slot antennas are formed in one side of the first waveguide, and one end of each first slot antenna is connected with the corresponding first coupling window; the other end of each first slot antenna is arranged in the heating box, one side of the second waveguide is provided with a plurality of second coupling windows corresponding to the second slot antennas, one end of each second slot antenna is connected with the corresponding second coupling window, and the other end of each second slot antenna is arranged in the heating box; and a plurality of microwave holes are formed in the side, facing the corresponding second slot antenna, of each first slot antenna, a plurality of microwave holes are formed in the side, facing the corresponding first slot antenna, of each second slot antenna, and microwaves pass through the microwave holes to heat materials between the first slot antennas and the second slot antennas. The microwave thawing device provided by the invention is more uniform in heating, and adopts a coupling window form for distribution, so that the equipment is simplified.

Description

technical field [0001] The invention relates to the technical field of microwave thawing, in particular to a microwave thawing device. Background technique [0002] The key points of microwave thawing of industrial meat products are its uniformity and production capacity. Large-scale meat processing plants have a high degree of automation and a large amount of thawing, and have high requirements for the uniformity of thawing and thawing capacity. [0003] The existing microwave thawing equipment mostly adopts pyramidal antenna to feed waves, and the power distribution is a standard power divider. The pyramid antenna is fed sideways, and the microwave cannot directly irradiate the upper and lower surfaces of the material, so the efficiency is low. Moreover, the feed energy of the pyramid antenna is relatively concentrated, which may easily cause excessive energy density in some areas and affect the thawing effect. The power distribution of the power divider can only be div...
