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

[0046] 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 .

[0047] The cylinder body 110 may define a heating chamber for placing the object to be treated 170 , and a pick-and-place opening may be opened on the front wall thereof for taking and placing the object to be treated 170 .

[0048] 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.

[0049] At least a part of the electromagnetic wave generating system may be disposed in the barrel 110 or connected to the barrel 110 to generate electromagnetic waves in the heating chamber to heat the object 170 to be treated.

[0050] The cylinder body 110 and the door body may be r...

Abstract

The invention provides a heating device. The heating device comprises a cylinder for placing an object to be treated and an electromagnetic wave generating system for generating electromagnetic waves in the cylinder to heat the object to be treated. The electromagnetic wave generation system comprises a plurality of radiation groups and a phase shifter. Each radiation group comprises a plurality of radiation units and a plurality of radiation groups used for radiating electromagnetic waves. The phase shifter is configured to adjust the direction of the electromagnetic waves radiated by the plurality of radiation units of the plurality of radiation groups. The heating device is provided with the plurality of radiation groups and the phase shifter for adjusting the direction of the electromagnetic waves radiated by the plurality of radiation groups, and each radiation group comprises the plurality of radiation units, so that each part of the to-be-treated object can be accurately heated in a targeted manner, the bad phenomenon that the to-be-treated object is locally overheated and even is thoroughly cooked is reduced, the loss of nutritional ingredients is reduced, and the quality of the unfrozen food materials is improved.

Description

technical field [0001] The invention relates to the field of food processing, in particular to an electromagnetic wave 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.). Contents of the invention [0004] An object of the present in...
