Description

Technical Field

[0001] The utility model belongs to the technical field of food processing equipment, in particular to a safe meat grinder. Background Art

[0002] Food processing refers to the grain grinding, feed processing, vegetable oil and sugar processing, slaughtering and meat processing, aquatic product processing, as well as processing activities of vegetables, fruits, nuts and other foods that directly use agricultural, forestry, animal husbandry and fishery products as raw materials. With the development of modern industry, the requirements for food processing equipment are constantly increasing.

[0003] When processing meat food, a meat grinder is often needed. A meat grinder is a device used by meat processing companies to process raw meat into granular meat fillings according to different process requirements and processing specifications. When working, the raw meat is chopped up by the shearing effect formed by the rotating cutting blade and the perforated blade on the orifice plate, and the raw material is continuously discharged out of the machine under the action of the screw extrusion force. According to the different properties of the material and processing requirements, the corresponding knives and orifice plates can be configured to process particles of different sizes to meet the process requirements of the next process.

[0004] However, the current meat grinders still have certain defects and drawbacks in actual use: first, when the above-mentioned meat grinder is grinding the raw meat, it is necessary to manually pre-process the large pieces of raw meat, that is, to cut the large pieces of raw meat into small pieces of minced meat, and then put the minced meat into the feed port of the meat grinder, and use the shearing effect formed by the rotating cutting blade and the perforated blade on the orifice plate to cut the raw meat into pieces. The workload of the workers in this process is relatively large, and the cutting efficiency of the raw meat is low; secondly, since the feed port of the meat grinder is connected to the internal screw, when performing the feeding operation, the staff holds the meat and puts it into the feed port. In this process, the operator's hand is easily brought into the meat grinder, causing the hand to contact the screw, which is easy to cause safety accidents and has poor safety. Therefore, it is urgent to design a safe meat grinder to solve the above problems. Utility Model Content
