Technical Field

[0001] The invention relates to the technical field of meat product preservation, in particular to a method for preserving meat products. Background Art

[0002] Meat products refer to cooked meat products or semi-finished products made from livestock and poultry meat as the main raw material and seasoning, such as sausage, ham, bacon, braised meat, barbecued meat, etc. In other words, all meat products made from livestock and poultry meat as the main raw material and with added seasonings, regardless of the processing technology, are called meat products, including: sausage, ham, bacon, braised meat, barbecued meat, dried meat, jerky, meatballs, prepared meat skewers, meat patties, cured meat, crystal meat, etc. The packaging materials of meat products include natural casings, artificial casings, collagen casings, fiber casings, plastic casings, cellophane casings, composite films and plastic wrap, etc. Fresh-keeping is to keep perishable foods such as vegetables, fruits and meat fresh. Commonly used terms include cling film, food preservation, and improved aquatic product preservation technology. Fresh meat cabinets are refrigerators used to refrigerate and display fresh meat. By lowering the temperature in the cabinet to two to eight degrees, the activity rate of bacteria in fresh meat is slowed down, thereby extending the shelf life of fresh meat. There are air-cooled open type and direct-cooled arc glass cover on the market.

[0003] For example, the patent document with the announcement number CN 111481019 B discloses a meat product preservation rack, which is used to realize the orderly placement of meat products. It includes: a rotating drum, which rotates at a uniform speed in a vertical plane under the action of a driving mechanism; a support rod, which is a plurality of groups evenly arranged on the cylindrical outer wall of the rotating drum, and the two support rods arranged in groups are located on the same busbar; a movable tray, which is rotatably mounted on the support rod at one end away from the axis of the rotating drum; a first and a second sliding tray, which are slidably arranged between the two support rods arranged in groups and are rotatably connected to the support rod; a first and a second driving plate, a driving shaft is provided on the slider, and when the driving shaft contacts the inner wall of the first driving plate, the first sliding tray moves along the length direction of the support rod, and when the driving shaft contacts the inner wall of the second driving plate, the second sliding tray moves along the length direction of the support rod. The present invention can facilitate the preservation, display and acquisition of meat products.

[0004] However, due to the limitation of its own structure, this structure can only perform a single preservation method of freezing the meat products as a whole. In the actual selling process, some meat products often need to be sold in a completely thawed state. However, the meat product preservation support structure cannot perform a more suitable overall thawing operation for meat products, and the blood that may be generated when the meat products are thawed cannot be effectively collected and processed. At the same time, the equipment cannot perform efficient and synchronous preservation and storage operations of frozen meat products and thawed meat products, and cannot meet daily use needs. Therefore, it is urgent to design a meat product preservation method to solve the above problems. Summary of the invention

In actual use, a staff member first starts the driving unit inside the fresh-keeping cabinet, and the driving unit starts to drive the conveyor belt and all the ventilation racks to rotate as a whole through the driving rollers at the upper and lower ends. At this time, the electric push rod on the front of the storage rack is started in turn, and the magnetic suction plate at one end can be driven as a whole to rotate each group to the meat storage liner inside the ventilation rack at the material trough for rapid adsorption. Then, a limited pull-out operation is performed to deliver the meat storage liner to the meat product to be thawed in the meat storage liner inside the ventilation rack. The ventilation mesh grooves on the side of the ventilation rack are used for breathable loading operations. After loading is completed, the meat storage liner is sent back to the ventilation rack for storage. At this time, the ventilation rack evenly delivers the fresh-keeping cold air flow from the uniform air grille through the internal diversion bottom pipe and diversion side pipe. After the ventilation rack evenly delivers the fresh-keeping cold air into the interior of the fresh-keeping cabinet, the air flow inside the fresh-keeping cabinet can be accelerated, so that the frozen meat products inside the ventilation rack can be quickly thawed, and the continuous fresh-keeping cold air flow can also be used to effectively and continuously thaw and preserve the fresh-keeping cold air flow. At the same time, the drive unit and drive roller are started daily to rotate the conveyor belt as a whole in an orderly manner. While the meat products can be quickly loaded and unloaded at the control frame, the drain guide operation can be performed quickly through the drain guide plate on the back of the ventilation rack to discharge all the thawed blood water from the drain trough on the bottom wall of the fresh-keeping cabinet to ensure the quality of the meat products when they are sold, which reflects the practicality of the equipment design.

[0020] The meat product preservation method further improves the overall use effect of the equipment by arranging the fresh-keeping cabinet, the liquid receiving rack, the temperature conducting rack, the refrigeration pipe group, the refrigeration unit, the freezing cabinet, the movable shaft, the sealing door, the layering plate, the temperature conducting plate, the ventilation grille, the air distribution rack, the air distribution inner pipe, the water storage tank, the ice-making plate and the pumping seat. In the daily use process, the staff can start the refrigeration unit to make it freeze the meat products inside the freezing cabinets on both sides through the refrigeration pipe group. The two groups of freezing cabinets can also perform efficient classification and freezing storage operations for meat products through the movable shaft and the sealing door and the internal layering plate at the front, so as to provide meat products thawed and sold inside the fresh-keeping cabinet. Efficient and stable replenishment operation, the two work together to achieve better meat preservation and sales operations. The refrigeration pipe group can guide part of the cold air upward through the ventilation grille, and enter the interior of the ventilation rack from the air distribution rack and the air distribution inner pipe at both ends of the temperature conduction rack, making the overall meat preservation of the equipment more energy-efficient. At the same time, the temperature conduction plate at the top of the freezer can be connected to the temperature conduction rack, and then the temperature is conducted at the ice-making plate on the bottom wall of the water storage tank inside the liquid collection rack, so that the blood water falling from the drainage trough can be re-frozen when collected inside the water storage tank to avoid corrosion and pollution. Subsequently, it is cleaned uniformly through the pumping seat, which reflects the comprehensiveness of the equipment design. BRIEF DESCRIPTION OF THE DRAWINGS
