Radio frequency power source and radio frequency unfreezing device

Abstract

The invention relates to the technical field of radio frequency unfreezing, in particular to a radio frequency power source and a radio frequency unfreezing device. The radio frequency unfreezing device comprises the radio frequency power source. The radio frequency power source comprises a phase-locked frequency source, a controller, a first amplifier and a phase regulating circuit, wherein the first amplifier is connected between the phase-locked frequency source and the phase regulating circuit, and the controller is respectively connected with the phase-locked frequency source and the phase regulating circuit. The controller controls the frequency and on and off of the phase-locked frequency source. The phase-locked frequency source generates a first signal under the control of the controller and transmits the first signal to the first amplifier. The first amplifier amplifies the first signal, then generates a second signal and transmits the second signal to the phase regulating circuit. The phase regulating circuit regulates the phase of the second signal and generates and outputs a third signal. By the arrangement, the frequency and power of the third signal output by the radio frequency power source can be controlled, and the problem that temperature in frozen meat is uneven when the unfreezing device is used to unfreeze the frozen meat is improved.

Description

technical field [0001] The invention relates to the technical field of radio frequency thawing, in particular to a radio frequency power source and a radio frequency thawing device. Background technique [0002] Frozen preservation of meat is a better method to keep the quality of meat stable, but when thawing frozen meat, different thawing methods have a great impact on the quality of thawed meat. Traditional thawing methods include air thawing and water thawing. During the thawing process, the heat is transferred from the surface of the meat to the inside by means of heat transfer. This method not only takes a long time to thaw, but also has a high loss rate of meat juice during the thawing process and is easily contaminated by microorganisms. etc., the quality of the meat after thawing will deteriorate. [0003] In the prior art, microwaves can be used to thaw frozen preserved meat, but the temperature difference between the surface temperature and the central temperatur...
