Device and method for pretreating low-fat beef

Abstract

The invention discloses a device and a method for pretreating low-fat beef. The device comprises a tumbling device, a microwave thawing device, and a conveying device, wherein the microwave thawing device is used for microwave thawing the beef, the conveying device is connected between the microwave thawing device and the tumbling device, and is configured to convey the beef in the microwave thawing device to the tumbling device, the tumbling device comprises a barrel, a weighing mechanism, a plurality of first adjusting parts, and a plurality of second adjusting parts, and the barrel is provided with a plurality of parallel first adjusting grooves and a plurality of parallel second adjusting grooves. The extension length of the first adjusting part and the second adjusting part can be adjusted according to different weights of beef. Since inner sides of the first adjusting part and the second adjusting part are curved, tumbling efficiency of the beef can be adjusted. When the first adjusting part and the second adjusting part are retracted to the first adjusting groove and the second adjusting groove, the barrel is circular, and the maximum rolling weight of the pretreatment device is applicable at the moment. By setting a pressing feeding device, when the beef is tumbled inside the barrel, and pressure is generated on the pressing feeding device, auxiliary materials containedin a first cavity and a second cavity are added to the beef, and due to different contact surfaces during the tumbling of the beef, the feeding can be made more uniform through multiple feedings, andthe tumbling efficiency and seepage effect can be improved.

Description

technical field [0001] The invention relates to the technical field of beef processing, in particular to a low-fat beef pretreatment device and method. Background technique [0002] In the process of beef processing, the beef is usually pretreated to improve the quality of the beef and facilitate subsequent processing operations. The pretreatment methods generally include thawing and tumbling; [0003] The traditional tumbling device is to place the beef in the drum, and the drum rotates to make the beef rub against each other and beat each other, so as to expand and soften the physical tissue of the beef. However, if the amount of meat in the tumbling drum is too small, it will cause rolling Excessive kneading will damage the quality of the meat, and if the amount of meat is too much, the efficiency of tumbling will decrease, and the uniformity of penetration of auxiliary materials will not be enough for the same tumbling time.
