Description

Technical Field

[0001] The invention relates to the technical field of livestock meat cutting and trimming, in particular to an energy-saving livestock meat cutting and trimming device. Background Art

[0002] When processing livestock meat, it is often necessary to cut and trim it to effectively separate different parts for subsequent packaging and further processing. The cutting and trimming process includes fat removal, myofascial stripping, and tenderizing the meat structure. Tenderizing, a crucial step in enhancing the taste and quality of meat, typically involves piercing the meat to disrupt the connective tissue and muscle fibers, reducing its toughness.

[0003] Chinese utility model patent CN215684537U discloses a meat tenderizer for processing meat. This device uses cutting spikes to pierce meat, severing tendons and connective tissue to achieve a tenderizing effect. However, during the tenderizing process, the muscle fiber structure of the meat is damaged, often resulting in the production of blood and tissue fluid. If these fluids are not separated in a timely and effective manner, they will not only affect subsequent processes such as curing and freezing, but also negatively impact the appearance and taste of the finished product.

[0004] To address these issues, existing technologies typically use high-speed centrifugation to separate blood and tissue fluid from tenderized meat. While this method can achieve good results when processing high-quality meat, it also consumes a lot of energy and requires a lot of equipment. When used to process medium- and low-quality meat, it not only results in additional energy consumption but also significantly increases processing costs, reducing overall economic efficiency. Therefore, existing technologies for separating liquids after meat tenderization still have room for improvement in terms of energy efficiency and cost control. Summary of the Invention

The segmentation knife 16 and the piercing tenderizing unit are arranged in sequence along the conveying direction. Each time the segmentation knife 16 performs upper and lower segmentation, there is an overlapping segmentation area to ensure that the meat is cut thoroughly. When the placement component is located at the lower side of the piercing tenderizing unit, the meat has left the segmentation area to prevent the meat from being repeatedly segmented and chopped. The two sides of the two lifting brackets 18 are respectively installed with a liquid nitrogen supply unit and a power unit. Furthermore, the puncture tenderizing unit includes a liquid nitrogen diverter shell 22, which is fixedly installed at the bottom of one of the lifting brackets 18.

[0037] Furthermore, the vibration assembly includes a guide plate 13, which is fixedly installed in the conveying bracket 1. A rotating rod 12 is rotatably installed on the guide plate 13 through a bearing. A camshaft 14 is fixedly installed outside the rotating rod 12.

A top plate 40 is fixedly mounted on the top of the guide rod 36, and a plurality of knocking balls 39 are fixedly mounted on the upper side of the top plate 40.

[0040] By means of the above structure: the bottom end of the guide rod 36 is spherical, which is convenient for fitting the guide plate 13 for guidance. When it is on the horizontal guide surface of the guide plate 13, the guide rod 36 is in the maximum movement position. At this time, the top plate 40 and the knocking ball 39 on the upper side of the guide rod 36 can limit the placement plate 6 to prevent it from shaking during cutting and trimming. When it moves to the position of the camshaft 14, the camshaft 14 rotates and squeezes the guide rod 36, causing the guide rod 36 to move up and down. The guide rod 36 drives the top plate 40 to move, and the top plate 40 drives multiple knocking balls 39 to move up and down to knock on the placement plate 6, and under the action of multiple springs 32, the placement plate 6 vibrates.

[0041] Furthermore, an anti-slip layer is provided on the upper side of the placement plate 6 .

[0042] By means of the above structure, the anti-slip layer increases the friction between the meat and the meat, thereby preventing the meat from sliding on the placement plate 6.

[0043] Working principle: When the device is in use, first connect the one-way external pipe 25 to liquid nitrogen, use the controller 47 to start the conveying motor 2, the conveying motor 2 drives the corresponding drive shaft 9 to rotate, the drive shaft 9 drives the two transmission wheels 8 to rotate, and the two transmission wheels 8 respectively drive the two conveyor chain belts 7 to move synchronously, so that the conveyor chain belt 7 drives the drive plate 38 to move, the drive plate 38 drives the conveying plate 31 to move through the overhead column 37, the conveying plate 31 drives the pipe sleeve to move, the pipe sleeve drives multiple slide rods 34 to move, and the multiple slide rods 34 drive the same placement plate 6 to move, so that the placement plate 6 starts working.

[0044] The meat to be tenderized is placed on the placement plate 6, and the placement plate 6 moves on the conveying bracket 1, driving the guide rod 36 to move, so that the guide rod 36 is close to the guide plate 13, and under the guidance of the guide plate 13, the top plate 40 is driven to move upward, and the top plate 40 drives the knocking ball 39 to move upward, so that the knocking ball 39 pushes the placement plate 6 upward and limits it, and the driving motor 4 is started by the controller 47. The output end of the driving motor 4 drives the driving disk 20 to rotate, and the driving disk 20 drives the driving block 21 to move, and the driving block 21 drives the reciprocating block 19 to move up and down under the limiting action of the two lifting brackets 18, thereby driving the two lifting brackets 18 The two lifting brackets 18 drive the mounting block 17 to move up and down, and the mounting block 17 drives the dividing knife 16 to move up and down to symmetrically divide the meat blocks. The divided meat blocks continue to be transported through the placement plate 6, and when the infrared transmitter 35 on the placement block moves to a direction perpendicular to the infrared receiver 29, the conveying motor 2 is paused for a period of time, and the other lifting bracket 18 drives the liquid nitrogen diversion shell 22 to move, and the liquid nitrogen diversion shell 22 drives the spray pipe 28 to move, and the spray pipe 28 drives the triangular pyramid thorn 48 to reciprocate up and down, and the triangular pyramid thorn 48 repeatedly punctures the divided meat blocks to destroy their internal fibrous tissue, thereby achieving the effect of tenderizing the meat blocks.

[0045] During the tenderizing process, when the liquid nitrogen diverter shell 22 moves downward, the connecting rod 27 is driven downward by the two lifting brackets 18, and the connecting rod 27 drives the piston 26 downward through the pull rod 24, so that a negative pressure is formed inside the nitrogen supply tank 50, and the liquid nitrogen is sucked in through the one-way external pipe 25. When the liquid nitrogen diverter shell 22 moves upward, it drives the piston 26 to move upward, and the sucked liquid nitrogen is injected into the liquid nitrogen diverter shell 22 through the liquid nitrogen pipe 23, and sprayed out through the atomizing nozzle 30 at the bottom end of the spray pipe 28, quickly freezing the triangular pyramid thorns 48, reducing the sticking of the meat block during the puncture process, and pre-freezing the punctured meat block to reduce the production of tissue fluid and blood.

[0046] After the puncture tenderizing is completed, the conveying motor 2 continues to start, driving the placement plate 6 to move. When the guide rod 36 disengages from the guide plate 13, the guide rod 36 is attached to the surface of the camshaft 14 under the action of gravity. At this time, the driving shaft 9 drives the secondary bevel gear 11 to rotate, the secondary bevel gear 11 drives the primary bevel gear 10 to rotate, the primary bevel gear 10 drives the rotating rod 12 to rotate, the rotating rod 12 drives the camshaft 14 to rotate, and the camshaft 14 squeezes the guide rod 36 to make the guide rod 36 move up and down. The guide rod 36 drives the top plate 40 to move, and the top plate 40 drives multiple knocking balls 39 to move up and down to knock on the placement plate 6, and under the action of multiple springs 32, the placement plate 6 vibrates, and the blood and tissue fluid are precipitated to the surface of the meat block through vibration, thereby improving the effect of the later liquid absorption treatment.

[0047] When the placement plate 6 moves to the cleaning rack 5 area, the lifting bracket 18 drives the lifting bracket 46 to move downward through the transmission rod 49. At this time, the winding roller 41 does not rotate. The lifting bracket 46 drives the winding roller 41 and the feeding roller 45 to move downward at the same time, and the blotting paper between the feeding roller 45 and the winding roller 41 is attached to the surface of the meat block after vibration, and the tissue fluid and blood precipitated on the surface of the meat block are adsorbed. When the lifting bracket 46 moves upward, the driving rack 44 drives the driving gear 43 to rotate, so that the winding roller 41 rotates, and cooperates with the rotational force to pull the blotting paper on the feeding roller 45 to make it rotate synchronously, and replace the blotting paper assembled on it to maintain its liquid absorption performance.
