Abstract

The present invention discloses a cooling and forming device for meat products, which comprises a frame, a tumbling barrel body, a driving assembly, a support frame, a first barrel cover and a liquid nitrogen conduction assembly. The support frame is connected to the frame, and the support frame is rotatably connected to the tumbling barrel body through an annular support. The driving assembly is connected to one end of the tumbling barrel body through a driving shaft and is used for driving the tumbling barrel body to rotate. A material port is arranged at the other end of the tumbling barrel body, and the material port is detachably connected to the first barrel cover. The liquid nitrogen conduction assembly is connected to the tumbling barrel body and is used for introducing liquid nitrogen into the interior of the tumbling barrel body. The liquid nitrogen is sprayed by a nozzle onto the raw materials inside the barrel body. Since liquid nitrogen is a liquid with an extremely low temperature and absorbs a large amount of heat when vaporizing, it can quickly take away the heat on the meat products to achieve cooling.

[0002] A tumbler uses the principle of physical impact to make the meat tumble up and down in the drum, collide with each other, and beat each other to achieve the effects of massage and pickling. Using a tumbler can make the meat evenly absorb the pickling, improve the binding force and elasticity of the meat, improve the taste and cross-section effect of the product, enhance the water retention capacity, and increase the yield rate.

[0022] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments. However, the specific implementation manners and embodiments described below are only for illustrative purposes and are not limitations on the present invention.

[0024] In the description of the present application, the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the technical features indicated.

[0025] After meat products are processed by tumbling, they usually need to be shaped. Before shaping, the meat needs to be in a slightly frozen state, that is, it is required that the temperature in the tumbling machine barrel reaches -1 to -3°C. This temperature can achieve the best plasticity for meat products and can improve the subsequent processing ability of food. Existing tumbling machines usually cool down by using ice cubes, ice water, etc. The operation is cumbersome, the temperature control is inaccurate, and the required temperature cannot be reached inside the barrel. In addition, the refrigeration efficiency is relatively low, consuming time and effort. To solve the above technical problems, as Figures 1-6 shown, the present invention relates to a cooling and forming device for meat products, including a frame 1, a tumbling barrel 2, a driving assembly, a support frame, a first barrel cover 4, and a liquid nitrogen conduction assembly. The support frame is connected to the frame 1 and is located inside the frame 1. Specifically, the support frame includes a first cross beam 5, a second cross beam 6, longitudinal beams 7, and an oil cylinder 8. The two longitudinal beams 7 are symmetrically arranged. The two ends of the first cross beam 5 are respectively connected to the two longitudinal beams 7. The two ends of the second cross beam 6 are respectively connected to the two longitudinal beams 7. One end of the longitudinal beam 7 is rotatably connected to the frame 1. The tail of the oil cylinder 8 is rotatably connected to the frame 1 through a hinge seat. The piston rod of the oil cylinder 8 is rotatably connected to the longitudinal beam 7. The oil cylinder 8 is used to drive the longitudinal beam 7 to rotate around its hinge point with the frame 1. A ring-shaped support 9 is installed on the second cross beam 6. The support frame is rotatably connected to the tumbling barrel 2 through the ring-shaped support 9. The driving assembly is connected to one end of the tumbling barrel 2 through a driving shaft 16 and is used to drive the tumbling barrel 2 to rotate, as Figure 2In the shown state, the piston rod of the oil cylinder 8 is in a contracted state. At this time, it is the angle at which the tumbling barrel 2 inclines in the working state. The meat products in the tumbling barrel 2 rotating at this angle can be more evenly tumbled and massaged. When the piston rod of the oil cylinder 8 extends, the tumbling barrel 2 tends to be in a horizontal state, which is convenient for loading or unloading materials.

[0026] The liquid nitrogen conduction component is connected to the tumbling barrel 2 and is used to introduce liquid nitrogen into the interior of the tumbling barrel 2. Specifically, the liquid nitrogen conduction component includes a liquid nitrogen inlet pipe 10 and a nozzle 11. The liquid nitrogen inlet pipe 10 is installed on the frame 1. Preferably, it further includes a nitrogen inlet pipe 12. A control valve 13 is provided between the nitrogen inlet pipe 12 and the liquid nitrogen inlet pipe 10. The control valve 13 includes a ball valve, a solenoid valve, etc. The control valve 13 is connected with a conduit 14. The nitrogen inlet pipe 12 is used to introduce gaseous nitrogen, which can be used as a protective gas. The liquid nitrogen inlet pipe 10 can pass through liquid nitrogen after being connected to a liquid nitrogen storage tank. It is adjusted and controlled through the control valve 13. One end of the drive shaft 16 away from the tumbling barrel 2 is provided with a pipe interface 15. The conduit 14 is connected to the pipe interface 15 through a metal hose (not shown in the figure). A through hole is provided inside the drive shaft 16, and the through hole is communicated with the pipe interface 15. The nozzle 11 is installed on the outer wall of the tumbling barrel 2 and the nozzle orifice of the nozzle 11 is located in the inner cavity of the tumbling barrel 2. The nozzle 11 is communicated with the through hole of the drive shaft 16 through a branch pipe 17. After the liquid nitrogen is introduced, it is finally sprayed into the interior of the tumbling barrel 2 through the nozzle 11. The liquid nitrogen is sprayed by the nozzle on the raw materials inside the barrel. Since liquid nitrogen is a liquid with an extremely low temperature, it absorbs a large amount of heat when vaporizing, and can quickly take away the heat on the meat products to achieve cooling. By adjusting the control valve 13, the input of liquid nitrogen can be controlled, so as to achieve precise temperature control. Using liquid nitrogen as a refrigerant has a high cooling efficiency, and can make the meat products in a slightly frozen state, which is convenient for subsequent shaping processing.

[0027] Considering that if only a set of nozzles 11 are used for fixed-point spraying to cool down, it will cause uneven temperature inside the tumbling barrel 2 and it is also impossible to fully and evenly contact the internal meat products for cooling. The drive assembly includes a drive motor 18 and a reducer 19. The liquid nitrogen conduction assembly further includes a hexagonal pipe 20. The drive motor 18 is connected to the reducer 19. The drive shaft 16 is connected to the reducer 19 through a flat key. The drive shaft 16 is installed on the first cross beam 5 of the support frame through a bearing seat 21. The hexagonal pipe 20 is surrounded outside the drive shaft 16. At both ends of the drive shaft 16, there is a horizontal pipe 22 respectively. One end of the horizontal pipe 22 is communicated with the inner hole of the drive shaft 16, and the other end of the horizontal pipe 22 is connected to the hexagonal pipe 20. There are three branch pipes 17, and the three branch pipes 17 are evenly arranged at intervals along the circumferential direction of the tumbling barrel 2. One end of the branch pipe 17 is connected to the hexagonal pipe 20, and the other end of the branch pipe 17 is connected to the nozzle 11 through a bent pipe. Preferably, a side interface is further provided on the branch pipe 17, and each side interface is connected to a nozzle 11 through a bent pipe. Through the arrangement of the three branch pipes 17 and the six nozzles 11, the nozzles 11 can spray liquid nitrogen simultaneously from multiple directions, so that the liquid nitrogen is fully and evenly sprayed into the tumbling barrel 2, the overall temperature inside the tumbling barrel 2 is consistent, and all the meat products inside can evenly and fully contact the liquid nitrogen and remain in a slightly frozen state, making the product quality more stable. It is worth mentioning that due to the ingenious design of the pipeline, through the conduction of the inner hole of the drive shaft 16 and the arrangement of the annular pipe fittings, the branch pipe 17 can move synchronously with the tumbling barrel 2 around the circumferential side of the tumbling barrel 2.

[0028] In this embodiment, it is further preferred that a limiting rod 23 is provided at the bottom of the end of the longitudinal beam 7 away from the second cross beam 6. A disc 24 is provided at the bottom of the limiting rod 23, and a support block is provided on the cross bar of the frame 1. After the support frame rotates to a certain angle, the disc 24 abuts against the support block for limit protection.

[0029] At the other end of the tumbling barrel body 2, there is a material inlet, and the material inlet is detachably connected to the first barrel cover 4. To prevent the pressure inside the tumbling machine barrel from being too high, the first barrel cover 4 is provided with an exhaust pipe 25. Further, one end of the second cross beam 6 is provided with a suspension 26, a rotating shaft 27 is rotatably connected to the suspension 26, a crank 28 is provided at the bottom end of the rotating shaft 27, the top of the rotating shaft 27 is connected to the air outlet pipe 30 of the first barrel cover 4 through a bracket 29, the air outlet pipe 30 is communicated with the inner cavity of the tumbling barrel body 2, the exhaust pipe 25 is fixedly arranged on the air outlet pipe 30 and communicated with the air outlet pipe 30, and the exhaust pipe 25 is perpendicular to the air outlet pipe 30. By rotating the crank 28, the first barrel cover 4 can be opened and closed, which is more convenient. The exhaust pipe 25 is used to discharge the gas inside the tumbling barrel body 2 to reduce the pressure. An adjustable baffle 31 with a shape matching the inner hole is arranged in the exhaust pipe 25. The adjustable baffle 31 is connected with a movable shaft 32 through a bolt member. The axis of the movable shaft 32 is perpendicular to the axis direction of the exhaust pipe 25. The movable shaft 32 is rotatably connected to the exhaust pipe 25. A fixed seat 33 is arranged on the outer side of the exhaust pipe 25. A movable piece 34 is arranged on the fixed seat 33. An arc-shaped bending groove 35 is arranged on the movable piece 34. A limit bolt 36 is arranged between the fixed seat 33 and the movable piece 34. The limit bolt 36 is located in the arc-shaped bending groove 35. One end of the movable shaft 32 extends out of the exhaust pipe 25 and passes through the fixed seat 33 and then is fixedly connected to the movable piece 34. The staff can turn the movable piece 34 to make the movable shaft 32 rotate. The rotation angle and rotation range of the movable piece 34 can be limited by the limit bolt 36. The arc-shaped bending groove 35 is the movable path of the movable piece 34. The adjustable angle of the adjustable baffle 31 enables the discharge amount of the exhaust pipe 25 to be controlled, so that auxiliary pressure relief and temperature adjustment can be carried out.

[0030] Further, two support rods 37 are symmetrically arranged on the second cross beam 6. A cross bar that can rotate is arranged between the ends of the two support rods 37. The cross bar is connected with a fixed frame 38. The fixed frame 38 is connected with a second barrel cover 3. One end of the cross bar is connected with a rotation driving mechanism. The second barrel cover 3 is a barrel cover commonly used in the tumbling machine, and the second barrel cover 3 can be selectively used for covering.
