This application claims priority to Chinese Patent Application Number 2023222897396, filed Aug. 24, 2023.
The utility model relates to the technical field of meat processing, in particular to a meat tenderizer with adjustable spacing.
Meat tenderizing is required when processing meat food. The muscle fiber tissue of meat pieces is destroyed, thereby tenderizing the meat. The usual working process of the meat tenderizing equipment currently used for meat tenderizing (such as a beef tenderier disclosed by CN208956839U) is as follows: the meat pieces of specific thickness are placed between the two tenderizing rollers of the tenderizer, and after the tenderizer is in operation, the meat pieces are tenderized by cutting the tendons. When using this meat tenderizer to cut the tendons of meat pieces, the distance between the two breaking rollers cannot be adjusted. Therefore, the meat tenderizer can only cut the tendons of meat pieces of specific thickness. At the same time, when in use, it needs to cut the meat pieces into a consistent thickness before tenderizing, which is troublesome to use.
The utility model aims to provide a meat tenderizer with adjustable spacing to solve the defects of the current art, which has the advantage of adjusting the gap distance between the driving and driven tendon cutting rollers, so that the meat tenderizer can adapt to different thicknesses of meat pieces, without the need to cut the meat pieces into the same thickness to cut the tendons and tenderize the meat pieces
