CN-121990230-A - Packaging automation system for meat processing through frozen meat and frozen meat

Abstract

The invention relates to a packaging automation system for meat processing by frozen fresh and frozen meat, which comprises the steps of transporting raw pork provided by meat processing companies to a bone workbench, manually separating bone parts of the bone meat from the raw pork, processing the bone parts of the meat into parts, namely front leg meat, rear leg meat, neck meat, pork tripe and ribs, spraying sterilizing gas on the surface of the bone meat to sterilize the surface, penetrating the surface of the bone meat by an injection needle, injecting a food additive into an infusion part through an injection tube connected with the injection needle, putting the fixed meat into a freezing chamber and freezing the fixed meat into a frozen part of frozen meat, cutting the frozen meat into a certain size, putting the frozen meat into a packaging container, covering a film on the upper part, generating vacuum pressure between the film and the packaging container, sucking and discharging air in the frozen meat, and adhering the film on the frozen meat.

A package automation system, comprising: after transporting live pork supplied by meat processing companies to a bone work table, manually separating bones from the live pork; processing orthopaedics part of meat, dividing into several parts, namely front leg meat, rear leg meat, neck meat, spade belly and rib; a part to be sterilized by spraying a sterilizing gas on the surface of the bone and meat; penetrating the surface of bone and meat with an injection needle, and injecting the infusion part of the food additive through an injection tube connected with the injection needle; Placing the fixed meat in a freezer and freezing to form a frozen portion of frozen meat; Cutting frozen meat into pieces, placing into packaging container, covering the upper part with film, generating vacuum pressure between the film and packaging container, and sucking and discharging air to adhere the film to frozen meat.

Description

Packaging automation system for meat processing through frozen meat and frozen meat Technical Field The present invention relates to a packaging automation system for meat processing by means of frozen and fresh meat. Background In recent years, the meat industry has been freed from traditional distribution by meat stores, by creating brands of centralized distribution networks, distributed in the form of chilled or frozen meats. The frozen meat-centric meat industry has established the concept of branded frozen meat, and from the start of small-scale slaughter processing, large-scale advanced meat processing plants are increasing, and various factors related to microbial contamination of meat are being regulated to provide fresh status to consumers, which is evolving into a storage and quality-centric production method and sanitation of meat. Thus, thanks to the development of meat packaging technology, it is possible to sell not only meat in supermarkets and department stores without slaughtering equipment, but also consumers can easily purchase it through online shopping, and also in boxes that only allow identification of part of the meat. In view of this, in order to provide sanitary and high-quality meat products to consumers in an optimal state, various packaging methods are employed depending on the location and sales form of meat, and basically, it is required to preserve foods in an initial state as much as possible in terms of freshness, taste, nutritional ingredients and appearance by using a packaging material satisfying characteristics such as oxygen barrier, transparency, impact resistance, heat shrinkage and simplicity required for food packaging characteristics. On the other hand, depending on the final packaging conditions, distribution process and shelf life of the meat, it is necessary to change the necessary packaging conditions to maintain freshness and bright red color of the meat. Korean registered patent No. 10-0775967 discloses a "meat compound packing method". The prior patent specifies (a) a step of packing meat with an oxygen permeable membrane after the meat is placed in an inner container and (b) a step of packing meat with a skin in an outer container larger than the inner container and degassing the air-conditioning with oxygen using an airtight film. However, the conventional meat compound packaging method can prevent the premature deterioration of meat caused by anaerobic bacteria while maintaining the shape of the packaged product, but has the problem of complex packaging process, not only increases the manufacturing cost, but also has the defect that the discoloration phenomenon of the meat cutting surface cannot be slowed down. Prior art literature Patent literature Patent document 1 Korean patent application No. 10-2006-0132939 Disclosure of Invention Problems to be solved by the invention The present invention is directed to solving the problems of the conventional art and an object of the present invention is to provide a packaging automation system capable of rapidly delivering high quality pork to wholesalers or consumers of pork carcasses from the supply of pork carcasses to the molding, freezing and post-refrigeration packaging by meat processing of chilled and frozen meats. Means for solving the problems The invention aims to transfer raw pork supplied by meat processing companies onto a bone workbench, then separate bones and meat from the raw pork by manpower, process orthopaedics parts of the meat into parts of front leg meat, rear leg meat, neck meat, pork belly and ribs, sterilize the surfaces of the bone meat by spraying sterilizing gas, puncture the surfaces of the bone meat by injection needles, inject infusion parts of food additives through injection tubes connected with the injection needles, place the fixed meat into a freezing chamber and freeze the fixed meat into frozen parts of frozen meat, cut the frozen meat into a certain size, place the frozen meat into a packaging container, and after the upper part is covered with a film, generate vacuum pressure between the film and the packaging container, suck and discharge air in the film to adhere the film on the frozen meat, and can be realized by the meat processing of fresh and frozen meat through a packaging automatic system. The sterilizing part is to inject sterilizing gas into the sterilizing device and seal the sterilizing gas for 30-60 seconds, the sterilizing gas is ozone or chlorine dioxide (ClO 2), the sterilizing device is a sterilizing chamber body with a bone and meat storage container, the sterilizing chamber body is opened and closed, a cover plate formed by a gas injection tube and shafts formed by two sides of a storage box are hinged and adhered with inner walls formed by two sides of the sterilizing chamber body and can be rotationally formed, a driven pulley is connected to a shaft on one side, and a belt is connected to a driving pulley. In the infusion part, the food additive is
