[0002] As a high-end Western-style food, the quality and taste of steak are affected by many factors, among which the raw material processing of beef is one of the key steps to determine its final taste. There is often an oil film on the surface of beef blocks, which is mainly composed of fat and connective tissue on the surface of the meat. Although this oil film can provide flavor to the meat to a certain extent, too much oil film not only affects the taste of steak, but may also cause excessive oil seepage during the grilling process, increase oil smoke and affect the flavor. Therefore, during the processing of steak, it is usually necessary to remove the oil film on the surface of the meat to improve its processing quality and eating experience.

[0003] Before removing the oil film, the steak raw meat is usually cut into rectangular blocks, and then the oil film removal work is carried out; traditional oil film removal mostly relies on manual operation, using a handheld knife to start along one side edge of the meat block and slowly cut the oil film layer and the meat layer apart. Due to the need for manual operation, the manual removal process is not only labor-intensive, but also the skill differences of each operator will directly affect the removal effect, resulting in unstable processing quality of steaks, especially when processing large quantities of beef, which greatly increases production time and labor costs; therefore, there is a problem of low efficiency of oil film removal in the prior art.

The conveying direction of the raw meat by the conveying mechanism 400 is the same as the axial direction of the mounting bars 200.

[0035] A pressing and cutting mechanism 500 is provided above the conveying mechanism 400. The pressing and cutting mechanism 500 includes a pair of vertically placed support bars 501. The two support bars 501 are respectively fixed on the two storage boxes 300. A horizontally placed connecting bar 502 is fixed between the two support bars 501. The axial direction of the connecting bar 502 is perpendicular to the conveying direction of the conveying mechanism 400. A horizontally placed fixing plate 503 is provided below the connecting bar 502. A lifting unit for driving the fixing plate 503 to move up and down is provided between the connecting bar 502 and the fixing plate 503. A first cutter 504 placed along the axial direction of the mounting bar 200 is fixed at the lower end of the fixing plate 503. The first cutter 504 is located in the symmetrical plane of the two mounting bars 200.

The strip grooves 5041 are coaxially arranged with the mounting bar 200, and the strip grooves 5041 pass through both ends of the first cutter 504 along the axis direction of the mounting bar 200. Coaxially arranged second cutters 505 are arranged in the strip grooves 5041. The two second cutters 505 are symmetrically arranged. The blades of the second cutters 505 are located at one end away from the symmetry plane of the two second cutters 505. A driving unit connecting the two second cutters 505 is provided on the fixed plate 503, and the driving unit is used to drive the two second cutters 505 to move away from or close to each other.

[0036] Place the block of raw steak meat at one end of the conveying mechanism 400, while ensuring that the oil film layer on the raw meat faces upwards, and that the plane where the first cutting knife 504 is located is located near the middle of the raw meat;

[0037] The conveying mechanism 400 is turned on to convey the raw meat to the bottom of the first cutter 504. When both ends of the raw meat along the axis direction of the mounting strip 200 are located below the first cutter 504, the conveying mechanism 400 is turned off, and the lifting unit is turned on to drive the fixed plate 503 and the first cutter 504 to move downward. The blade of the first cutter 504 cuts off the oil film layer on the raw meat. Then, according to the thickness of the oil film layer, the lifting unit drives the first cutter 504 to be inserted into the raw meat to a corresponding depth, so that the first cutter 504 drives the second cutter 505 to move downward. To the bottom of the oil film layer, and then start the driving unit, the driving unit drives the two second cutters 505 to move away from each other, the second cutters 505 move out of the strip groove 5041 and move horizontally along the axis direction of the connecting strip 502, the second cutters 505 move and cut between the oil film layer and the meat layer of the raw meat, so that the oil film layer and the meat layer are separated, after the oil film layer and the meat layer are cut and separated, the oil film layer is removed from the meat layer and placed in the storage box 300, and then the conveying mechanism 400 is turned on to convey the raw meat after the oil film treatment to the next process;

[0038] In the present application, by cooperating with the first cutter 504, the strip groove 5041, the second cutter 505, the lifting unit and the driving unit, the oil film layer on the raw meat block can be cut off from the middle first, and then the oil film layer and the meat layer can be automatically cut and separated from the middle to both ends at the same time, thereby improving the cutting and separation efficiency of the oil film layer and the meat layer, and the insertion depth of the first cutter 504 and the second cutter 505 into the raw meat can be adjusted according to the thickness of the oil film layer, thereby reducing the amount of meat layer removed when removing the oil film layer.

When the first cutting knife 504 cuts into the raw meat, the spring 507 squeezes and compresses, and the two pressure plates 506 press part of the raw meat on both sides of the first cutting knife 504, making it easier for the first cutting knife 504 to cut off the oil film and extend into the raw meat. At the same time, the pressing effect of the pressure plate 506 can make the second cutting knife 505 cut the oil film layer and the meat layer. The process is more stable and smooth, which helps to ensure that the oil film is completely removed and avoid excessive removal of the meat layer.
