Description

Technical Field

[0001] The invention relates to the technical field of meat pickling, in particular to an electrostatic field ultrasonic coupling tumbling machine and a meat pickling process based on the tumbling machine. Background Art

[0002] As a meat processing equipment, the tumbler plays a vital role in the food processing industry. In meat marination, the tumbler mainly promotes the absorption of marinade through physical impact and mechanical friction, thereby improving the tenderness and water retention of meat. The tumbler uses mechanical tumbling and pressing to make the meat flip up and down in the drum, collide and beat each other, thereby promoting the uniform distribution and absorption of the marinade. This mechanical action helps to relax muscle tissue and improve the tenderness and elasticity of meat. Although the tumbler can marinate meat, due to the lack of squeezing of meat, in order to relax the muscles of the meat, the meat needs to be beaten many times in the marinating drum, so the marinating time is longer. At present, there are also devices that shorten the marinating time of meat by squeezing. For example, the patent document with the publication number CN209089848U discloses a tumbling device for meat processing, which includes a frame, a placement slot, a motor, a rotating shaft, a cam, a first connecting rod, a first rotating sleeve, a second connecting rod, and a second rotating sleeve. Although the device performs an extrusion rolling friction treatment on the meat in the placement slot through the first rotating sleeve and the second rotating sleeve, thereby tumbling and kneading the meat, the tumbling and kneading effect of the meat is improved. However, since the distance between the first rotating sleeve and the second rotating sleeve is fixed, in actual use, due to the different types and sizes of the meat put in, the distance between the squeezing rollers needs to be adjusted, which makes it impossible to better apply to the marinating work of different meats.

[0044] By setting the gear 160 and the ring gear 170 at the rotating shaft of the driving motor 150 in this embodiment, the water pipe 110 can be rotated, thereby driving the water tank 280 to rotate, and the rotation of the extrusion seat 240 is achieved by the cooperation of the second strip block 630 at the water tank 280 and the second strip groove 430 at the annular portion 242; the rotation of the drum 230 is achieved by the cooperation of the first strip block 410 at the extrusion seat 240 and the first strip groove 510 at the drum 230.

[0045] In this embodiment, by setting up the driving mechanism structure, the water tank 280, the extrusion seat 240 and the roller 230 can be driven to rotate simply by driving the water pipe 110 to rotate, thereby better simplifying the structure of the electrostatic field ultrasonic coupling tumbling machine and facilitating the use of the staff.

9. The electrostatic field ultrasonic coupling tumbler for meat pickling according to claim 1, characterized in that: A second installation cavity (310) is also provided at the bottom end of the tumbling machine body (100), a semiconductor cooling plate (360) is provided in the second installation cavity (310) and is in contact with the outer wall of the tumbling cavity (210), a heat dissipation fin (370) is provided at the semiconductor cooling plate (360), and a heat dissipation fan (1120) for discharging heat from the second installation cavity (310) is provided at the tumbling machine body (100).

10. A meat pickling process based on the electrostatic field ultrasonic coupling tumbler according to any one of claims 1 to 9, comprising the following steps: Step 1: Drive the electric push rod (180) to adjust the water tank (280) and the extrusion seat (240), then put the meat to be marinated and the auxiliary materials from the feed hopper (1100) into the tumbling chamber (210), then start the drive motor (150) to extrude the meat through the inner wall between the extrusion part (241) and the expansion chamber (220); after the meat is marinated, open the sealing cover (2120) to allow the marinated meat and auxiliary materials to fall from the discharge port (2110); Step 2: close the sealing cover (2120), then drive the electric push rod (180) on one side of the tumbling machine body (100) until the second strip block (630) at the water delivery box (280) on the side slides out of the second strip groove (430), then start the driving motor (150) on the side to rotate the water delivery box (280) so that the water outlet hole (620) at the water delivery box (280) rotates to the corresponding position of the through hole (420) of the extrusion part, and then drive the electric push rod (180) on the side to make the second strip block (630) slide into the second strip groove (430).
