Problems solved by technology

However, due to the difference in the penetration and absorption of water and ice by microwaves, and the uneven distribution of substances inside the food, the melted area absorbs more energy, which is prone to problems of uneven thawing and local overheating (such as the fat part of pork belly). , chicken feet, fish tails, etc.)

Embodiment Construction

[0045] figure 1 is a schematic structural diagram of a heating device 100 according to an embodiment of the present invention. see figure 1 , the heating device 100 may include a barrel body 110 , a door body, an electromagnetic wave generating system and a controller 130 .

[0046] Specifically, the cylinder body 110 may define a heating chamber for placing the object 140 to be processed. The front wall or the top wall of the barrel 110 may be provided with a pick-and-place opening for picking and placing the object 140 to be processed.

[0047] The door body can be installed together with the cylinder body 110 through appropriate methods, such as slide rail connection, hinge joint, etc., for opening and closing the access opening.

[0048] At least a part of the electromagnetic wave generating system may be disposed in the cylinder body 110 to generate electromagnetic waves in the heating chamber to heat the object 140 to be treated.

[0049] In some embodiments, the ele...

Abstract

The invention provides an unfreezing control method for a heating device and the heating device. The heating device comprises a cylinder body and an electromagnetic wave generating system, wherein a heating chamber for placing an object to be treated is defined in the cylinder body. At least a part of the electromagnetic wave generating system is arranged in the cylinder body, and the electromagnetic wave generating system comprises an electromagnetic wave generating module for generating electromagnetic wave signals so as to generate electromagnetic waves in the heating chamber to heat a to-be-processed object. The control method comprises the following steps: sensing real-time temperatures of a plurality of sensing points of the to-be-processed object; calculating the average temperature of the plurality of sensing points according to the real-time temperatures, and comparing the highest temperature of the plurality of sensing points; and re-determining the power of the electromagnetic wave signals according to the average temperature, the highest temperature and the thawing progress, a user does not need to manually adjust the power according to experience, the undesirable phenomenon that the to-be-treated object is locally overheated and even is thoroughly cooked is relieved, the loss of nutritional ingredients is reduced, and the quality of the thawed food materials is improved.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a thawing control method for an electromagnetic wave heating device and a heating device. Background technique [0002] During the freezing process of food, the quality of food is maintained, but frozen food needs to be thawed before processing or consumption. In order to facilitate the user to thaw the food, the food is usually thawed by an electromagnetic wave heating device. [0003] Thawing food through the electromagnetic wave heating device is not only fast and efficient, but also has low loss of nutritional components of the food. However, due to the difference in the penetration and absorption of water and ice by microwaves, and the uneven distribution of substances inside the food, the melted area absorbs more energy, which is prone to problems of uneven thawing and local overheating (such as the fat part of pork belly). , chicken feet, fish tails, etc.).
