Abstract
Description
Technical Field
[0001] This utility model relates to the field of meat heat processing technology, specifically a temperature-controlled meat heat processing device. Background Technology
[0002] Meat heat processing refers to altering the physical and chemical properties of meat through heating to achieve specific cooking effects and food safety requirements. By heat processing meat, most microorganisms in the meat can be killed, ensuring food safety. In addition, high-temperature processing can destroy enzymes and bacteria in the meat, preventing food poisoning.
[0003] When meat is heat-processed, some processing devices can reach temperatures exceeding 200°C, causing amino acids and glucose in the meat to react and produce harmful substances such as heterocyclic amines. These substances are carcinogenic and mutagenic, and can harm human health. Therefore, there is an urgent need for a device that can flexibly control the temperature of meat to break the continuous high-temperature conditions for the formation of heterocyclic amines.

A honeycomb heating plate is installed inside the turntable, and the heating plate is controlled by a touch screen. Supports for positioning and installing the collection plate are fixedly installed on the outer array of the turntable.
[0007] As an optimization, the heating plate adopts a honeycomb porous structure to improve the uniformity of heat radiation and avoid local overheating.
[0008] As an optimization, the bottom side of the turntable is provided with an array of accessories for stable support corresponding to the uniform rotation heating component. The accessories include a fixed sleeve fixedly installed on the bottom side of the turntable, a sliding column slidably inserted inside the fixed sleeve, a spring fixedly installed between the sliding column and the top wall of the fixed sleeve, and a ball embedded at the bottom of the sliding column, and the ball rolling inside the uniform rotation heating component.
[0009] As an optimization, limit strips are fixedly installed on both sides of the inner wall of the fixed sleeve, and a limit groove is opened on the outer side of the sliding column, and the limit strip is slidably inserted into the limit groove.

[0011] The beneficial effects of this utility model are: This temperature-controlled meat heat processing device rapidly inactivates microorganisms on the surface of meat through a 30-second high-temperature rapid sterilization stage, followed by a 3-minute medium-temperature slow-release stage to promote internal cooking of the meat and inhibit the formation of heterocyclic amines. Finally, it enters a low-temperature circulation stage to avoid the accumulation of harmful substances due to continuous high temperatures. Thus, through a step-by-step temperature decrease and intermittent heating process, it breaks the continuous high-temperature conditions for the formation of heterocyclic amines.
[0012] This temperature-controlled meat heat processing device can drive the turntable to rotate by starting the servo motor, thereby heating the pork evenly.
