Description

Technical Field

[0001] The present invention relates to the technical field of meat curing, and specifically, to an electrostatic field ultrasonic coupling tumbler and a meat curing process based on the tumbler. Background Art

[0002] As a meat processing equipment, the tumbler plays a crucial role in the food processing industry. In meat curing, the tumbler mainly promotes the absorption of the curing solution through physical impact and mechanical friction, improving the tenderness and water retention of the meat. By means of mechanical tumbling and pressing, the meat tumbles up and down, collides with and beats against each other inside the drum, thereby promoting the uniform distribution and absorption of the curing solution. This mechanical action helps to relax the muscle tissue and improve the tenderness and elasticity of the meat. Although the tumbler can achieve meat curing, due to the lack of extrusion of the meat, in order to relax the muscle of the meat, the meat needs to be beaten multiple times in the curing drum, so the curing time required is relatively long. Currently, there are also devices for shortening the meat curing time through extrusion. For example, the patent document with the publication number CN209089848U discloses a tumbling device for meat processing, which includes a frame, a placement groove, 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 this device performs extrusion-type rolling friction treatment on the meat in the placement groove through the first rotating sleeve and the second rotating sleeve, so as to perform tumbling processing on the meat and improve the tumbling effect of the meat. 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 extrusion rollers needs to be adjusted, so it cannot be better applied to the curing work of different meats.

[0029] Embodiment 1

[0030] As Figure 1-3 shown, this embodiment provides an electrostatic field ultrasonic coupling tumbling machine, including a tumbling machine body 100. A cylindrical tumbling cavity 210 is provided in the tumbling machine body 100. A feed hopper 1100 communicating with the tumbling cavity 210 is provided at the upper end of the tumbling machine body 100, and a cover plate 1110 is provided at the feed hopper 1100. A discharge port 2110 is provided at the lower end of the tumbling cavity 210, and a sealing cover 2120 is provided at the discharge port 2110. Both ends of the tumbling cavity 210 expand outward along its axial direction to form a frustum-shaped expansion cavity 220. A drum 230 is rotatably provided in the tumbling cavity 210, and a driving mechanism for driving the drum 230 to rotate is provided at the tumbling machine body 100. An extrusion seat 240 capable of rotating synchronously with the drum 230 is provided in the drum 230. The extrusion seat 240 includes a frustum-shaped extrusion portion 241 and an annular portion 242 located in the drum 230. The extrusion seat 240 can move along the axial direction of the drum 230, and an adjusting mechanism for driving the extrusion seat 240 to move along the axial direction of the drum 230 to adjust the gap between the extrusion portion 241 and the inner wall of the expansion cavity 220 is provided at the tumbling machine body 100. A feed channel 250 communicating the tumbling cavity 210 and the expansion cavity 220 is provided at the upper end of the tumbling machine body 100, and a discharge channel 260 communicating the tumbling cavity 210 and the expansion cavity 220 is provided at the lower end of the tumbling machine body 100. A scraper 270 for scraping the meat at the bottom end of the tumbling cavity 210 to the upper end is provided on the outer side wall of the drum 230. Two first installation cavities 310 are further provided in the tumbling machine body 100, and the two first installation cavities 310 are oppositely arranged along the axial direction of the tumbling cavity 210. Two opposite tumbling cavity openings 320 are provided on the side wall of the tumbling cavity 210. The tumbling cavity openings 320 communicate with the first installation cavities 310. A sealing seat 330 for sealing the tumbling cavity openings 320 is provided in the first installation cavities 310. A metal conductive plate 340 for forming an electrostatic field is provided in the sealing seat 330, and an ultrasonic generator 350 is also provided in the sealing seat 330.

[0031] During use, first, the gap between the extrusion portion 241 and the inner wall of the expansion cavity 220 is adjusted by using the adjusting mechanism according to the type and size of the meat. Then, the meat to be pickled and auxiliary materials are put into the tumbling cavity 210 through the feed hopper 1100. Subsequently, the drum 230 and the extrusion seat 240 are driven to roll by the driving mechanism, so as to extrude the meat through the gap between the extrusion seat 240 and the expansion cavity 220.

[0032] In this embodiment, the electrostatic field ultrasonic coupling tumbling machine squeezes the meat through the gap between the extrusion seat 240 and the expansion cavity 220. It can not only meet the extrusion operations for different types and sizes of meat, but also enable the pickling auxiliary materials to come into full extrusion contact with the meat, which can preferably reduce the time required for pickling meat, thereby preferably improving the efficiency of pickling meat. The setting of the scraper 270 at the drum 230 can scrape the meat and auxiliary materials at the bottom end of the tumbling cavity 210 to the upper end and make them enter the gap between the extrusion part 241 and the inner wall of the expansion cavity 220 through the feeding channel 250, so as to realize the cyclic extrusion of the meat.

[0033] Among them, the metal conductive plates 340 in the two sealing seats 330 are the positive conductive plate and the negative conductive plate respectively, which are used to form an electrostatic field. Through the synergistic effect of the ultrasonic generator 350, the interaction between the electrostatic field and ultrasonic waves can be utilized through the electrostatic field and ultrasonic coupling technology to generate a synergistic effect, thereby improving the tenderness, water retention and flavor of the meat, and having no negative impact on the sensory characteristics of the meat products. The ultrasonic generator 350 can also be set with only one. Figure 3 As shown, a second installation cavity is also provided at the bottom end of the tumbling machine body 100. A semiconductor refrigeration sheet 360 that fits the outer wall of the tumbling cavity 210 is provided in the second installation cavity. Heat dissipation fins 370 are provided at the semiconductor refrigeration sheet 360, and a heat dissipation fan 1120 for discharging the heat in the second installation cavity is provided at the tumbling machine body 100.

[0034] When pickling meat, after the meat is added, the feeding hopper 1100 can be sealed through the cover plate 1110, and then the semiconductor refrigeration sheet 360 is started to cool the tumbling cavity 210 through the semiconductor refrigeration sheet 360, so that the tumbling cavity can maintain a low temperature during the pickling process, thereby avoiding the oxidation of the meat and the contamination of the meat caused by the growth of microorganisms.

[0035] Combined Figure 4 and Figure 5 As shown, a first strip groove 510 is provided on the inner wall of the drum 230, and a first strip block 410 that is in clearance fit with the first strip groove 510 is provided on the outer side wall of the annular part 242.

[0036] In this embodiment, through the setting of the first strip groove 510 and the first strip block 410, the extrusion seat 240 can not only rotate with the drum 230, but also move along the axis direction of the drum 230.

[0037] Combined Figure 6As shown, a water delivery tank 280 having the same shape as the extrusion seat 240 is provided in the extrusion seat 240. A magnet 610 for adsorbing the water delivery tank 280 to the extrusion seat 240 is provided on the outer wall of the water delivery tank 280. A water delivery cavity 290 is provided in the water delivery tank 280. Several groups of water outlet holes 620 are provided at the end of the water delivery tank 280 close to the extrusion part 241. An extrusion part through hole 420 matching the water outlet holes 620 is provided at the extrusion part 241. A water inlet mechanism for sending water source into the water delivery tank 280 is provided on the tumbling machine body 100.

[0038] In this embodiment, through the setting of the water delivery tank 280, after the meat is pickled, the expansion cavity 220 can be washed by the water flowing out through the water outlet holes 620 and the extrusion part through hole 420 of the water delivery tank 280, thus avoiding small pieces of meat from sticking to the inner wall of the expansion cavity 220, and thus better realizing the cleaning of the electrostatic field ultrasonic coupling tumbling machine.

[0039] Furthermore, the water delivery tank 280 can rotate synchronously with the extrusion seat 240. Several groups of second strip-shaped grooves 430 are provided on the inner wall of the annular part 242. In this embodiment, the number of groups of the second strip-shaped grooves 430 is twice the number of groups of the water outlet holes 620. A second strip-shaped block 630 which is in clearance fit with the second strip-shaped grooves 430 is provided on the outer side wall of the water delivery tank 280. A spring 2100 located between the two water delivery tanks 280 and used for pushing the second strip-shaped block 630 into the second strip-shaped grooves 430 is provided in the drum 230.

[0040] In this embodiment, through the setting of the second strip-shaped grooves 430 and the second strip-shaped blocks 630, the water delivery tank 280 can rotate synchronously with the extrusion seat 240, so that when cleaning the extrusion machine body 100, the water flowing out from the extrusion part through hole 420 can evenly wash the inner wall of the expansion cavity, thus further improving the cleaning effect of the inner wall of the expansion cavity 220. Setting the number of groups of the second strip-shaped grooves 430 to be twice the number of groups of the water outlet holes 620 can rotate the water delivery tank 280 during the pickling of the meat, so that the water outlet holes 620 are misaligned with the extrusion part through hole 420, thus avoiding smaller pieces of meat from entering the water delivery tank 280 under the extrusion action, and thus better improving the stability of the electrostatic field ultrasonic coupling tumbling machine during use.

[0041] Combined with Figure 7 As shown, the water inlet mechanism includes a water delivery pipe 110 provided at the water delivery tank 280. The end of the water delivery pipe 110 extends out of the extrusion part 241 and the expansion cavity 220. The end of the water delivery pipe 110 extending out of the expansion cavity 220 expands outward to form an annular groove 710. The water inlet mechanism further includes a water inlet pipe 120. A connecting flange 720 which is in clearance fit with the annular groove 710 is provided at the water inlet pipe 120. An annular cover plate 130 for limiting the connecting flange 720 in the annular groove 710 is provided at the annular groove 710.

[0042] In this embodiment, through the arrangement of the connecting flange 720 and the annular groove 710, not only can water flow be pumped into the water delivery pipe 110 through the water inlet pipe 120, but also the water delivery pipe 110 can rotate.

[0043] In this embodiment, the driving mechanism includes a mounting bracket 140 arranged at the tumbling machine body 100. A driving motor 150 is provided at the mounting bracket 140. A gear 160 is provided at the rotating shaft of the driving motor 150. A gear ring 170 meshing with the gear 160 is provided at the water delivery pipe 110. The gear ring 170 extends along the axis direction of the water delivery pipe 110 so that the gear ring 170 meshes with the gear 160 when the water delivery tank 280 is moved.

[0044] Through the arrangement of the gear 160 at the rotating shaft of the driving motor 150 and the gear ring 170 in this embodiment, the rotation of the water delivery pipe 110 can be realized, thereby driving the rotation of the water delivery tank 280. The rotation of the extrusion seat 240 is realized through the cooperation of the second strip 630 at the water delivery tank 280 and the second strip groove 430 at the annular part 242; the rotation of the drum 230 is realized through the cooperation of the first strip 410 at the extrusion seat 240 and the first strip groove 510 at the drum 230.

[0045] In this embodiment, through the arrangement of the driving mechanism structure, the rotation of the water delivery pipe 110 can drive the rotation of the water delivery tank 280, the extrusion seat 240 and the drum 230, thereby preferably simplifying the structure of the electrostatic field ultrasonic coupling tumbling machine and facilitating the use by the staff.

[0046] In this embodiment, the adjusting mechanism includes a mounting plate 730 arranged at the water delivery pipe 110. An adjusting groove 740 is formed between the mounting plate 730, the gear ring 170 and the water delivery pipe 110; A rotatable annular plate 750 is sleeved in the adjusting groove 740; The adjusting mechanism further includes an electric push rod 180 arranged at the mounting bracket 140. A connecting rod 190 is provided at the annular plate 750. The end of the piston rod of the electric push rod 180 is connected to the annular plate 750 through the connecting rod 190.

[0047] Through the arrangement of the adjusting mechanism, the water delivery pipe 110 can be driven to move by driving the electric push rod 180, thereby driving the water delivery tank 280 to move. The extrusion seat 240 is driven to move by the magnetic attraction between the water delivery tank 280 and the extrusion seat 240, so as to realize the adjustment of the gap between the extrusion part 241 and the inner wall of the expansion cavity 220.

[0048] Embodiment 2

[0049] In this embodiment, a meat curing process based on the electrostatic field ultrasonic coupling tumbling machine described in Embodiment 1 is provided, which includes the following steps:

[0050] Step 1: Drive the electric push rod 180 to adjust the water storage tank 280 and the extrusion seat 240. Then, put the meat and auxiliary materials to be pickled into the tumbling chamber 210 from the feed hopper 1100. 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 pickled, open the sealing cover 2120 so that the pickled meat and auxiliary materials fall from the discharge port 2110.

[0051] During pickling, vacuum pumping can be carried out first by a vacuum pump to ensure the pickling quality.

[0052] 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 630 at the water storage tank 280 on this side slides out of the second strip groove 430. Then, start the drive motor 150 on this side to rotate the water storage tank 280 so that the water outlet hole 620 at the water storage tank 280 rotates to the position corresponding to the extrusion part through hole 420. Then, drive the electric push rod 180 on this side so that the second strip 630 slides into the second strip groove 430. Then, drive the electric push rod 180 on the other side of the tumbling machine body 100 until the second strip 630 at the water storage tank 280 on this side slides out of the second strip groove 430. Then, start the drive motor 150 on this side to rotate the water storage tank 280 so that the water outlet hole 620 at the water storage tank 280 rotates to the position corresponding to the extrusion part through hole 420. Then, drive the electric push rod 180 so that the second strip 630 slides into the second strip groove 430.

[0053] Step 3: Inject water into the water storage tank 280 through the water inlet pipe 120. The water sprays out through the water outlet hole 620 and the extrusion part through hole 420, thereby flushing the inner wall of the expansion chamber 220. Start the drive motor 150 to clean the scraper 270 by the rotation of the scraper 270. After cleaning, open the sealing cover 2120 to drain the sewage.

[0054] Through the above process, not only can the pickling efficiency of the meat be improved better, but also the cleaning of the expansion chamber 220 and the tumbling chamber 210 can be achieved better.
