Description

Technical Field

[0001] The invention relates to the technical field of tumbling and kneading machines, and in particular to a meat tumbling and kneading device used for food processing. Background Art

[0002] A meat tumbler is a machine used specifically for meat processing. It mechanically rolls and kneads meat to facilitate the curing process. This machine is commonly used for curing meat products such as ham, bacon, sausage, etc. The main functions of a tumbler include promoting seasoning penetration, improving the taste of meat, and shortening the curing time. A tumbler generally consists of a rotatable drum and a kneading device. The rolling speed and time can be set during operation to achieve the desired processing effect.

[0003] A vacuum refrigeration tumbling machine is disclosed in the patent with patent publication number CN103027098A. In order to solve the technical problems of long refrigeration time and large local temperature difference of the vacuum refrigeration tumbling machine, the adopted technical solution is that the vacuum refrigeration tumbling machine includes a tumbling barrel connected to a frame, a main shaft fixedly connected to the tumbling barrel, and a driving mechanism connected to the main shaft. A refrigeration layer and a heat preservation layer are arranged in sequence between the inner and outer walls of the tumbling barrel. The key is: an intermediate refrigeration bin is added along the axis inside the tumbling barrel, a partition is arranged inside the intermediate refrigeration bin, and the intermediate refrigeration bin is divided into a water inlet bin and a water outlet bin by means of the partition. The water inlet bin is connected to the total water inlet by means of a first water inlet pipeline, the water outlet bin is connected to the water inlet of the refrigeration layer by means of a first water outlet pipeline, and the water outlet of the refrigeration layer is connected to the total water outlet by means of a second water outlet pipeline, so as to form a series cold water circulation system.

[0004] The prior art has the following defects:

[0005] The existing vacuum tumbling machines usually only have the rotation of the tumbling drum to drive the meat in the drum to rise to a certain height and then fall to achieve the mixing of the meat product and the seasoning. This results in the meat product, the seasoning and the pickling liquid not being mixed fully and evenly during operation, which makes the seasoning process long; small pieces of meat are easy to stick together, which makes the meat product not absorb the seasoning in the drum effectively; in addition, the cleaning of the tumbling drum is also more troublesome, and the meat often adheres to the surface of the drum. These residues are difficult to remove after tumbling, which brings inconvenience to the cleaning work. If the tumbling time is too long, the heat generated by friction may cause the meat product to be heated unevenly in the drum, thereby affecting the taste of the finished product. Summary of the invention

[0006] In view of the above problems in the prior art, a meat tumbling and kneading device for food processing is proposed.

[0007] The present application provides a meat tumbling and kneading device for food processing, the purpose of which is to improve the tumbling and kneading efficiency, shorten the tumbling and kneading time, loosen the adhered meat, increase the marinating effect of the meat, and tenderize the meat.

[0008] The technical solution of the present invention is: a meat material tumbling and kneading device for food processing, comprising a base, and also comprising:

[0009] A support frame is arranged above the base;

[0010] The rolling and kneading cylinder is arranged on the support frame, and its axis is in the horizontal direction;

[0011] A rotating mechanism, which is arranged on the support frame and in rolling contact with the wall of the tumbling and kneading drum, and is used to drive the tumbling and kneading drum to rotate;

[0012] A plurality of stirring rods are provided and distributed in a circular array on the inner wall of the tumbling and kneading cylinder along the axis of the tumbling and kneading cylinder, and are used to stir the meat;

[0016] Furthermore, the left and right ends of the stirring rod are horizontal rods, and the middle is a plurality of connected W-shaped curved rods.

[0017] By adopting the above scheme, by setting the middle of the stirring rod as a W-shaped curved rod, it is beneficial to use the W-shaped curved rod to break up the meat and prevent it from sticking. The left and right ends are set as horizontal rods to ensure that the two ends of the stirring rod rotate coaxially.

[0018] Furthermore, the self-rotation mechanism includes a partition plate arranged at the bottom of the tumbling drum, a rotating hole 1 arranged at the open end of the tumbling drum, and a sleeve arranged at the bottom of the tumbling drum. The left and right ends of the stirring rod are respectively rotatably arranged in the rotating hole 1 and the sleeve. The right end of the stirring rod passes through the partition plate and is rotatably connected to the partition plate. A support rod is arranged on the support frame.

A fixed gear is fixedly connected to the support rod. The right end of the stirring rod is connected to a rotating tooth through a flat key, and the rotating tooth is meshed with the fixed gear.

[0019] By adopting the above scheme, a self-rotation mechanism is provided. Since the fixed gear does not rotate when the tumbling and kneading drum rotates, the tumbling and kneading drum drives the rotating teeth to revolve orbitally while the rotating teeth mesh with the fixed gear. The rotating teeth rotate and drive the stirring rod to rotate. The stirring rod rotates while the tumbling and kneading drum revolves orbitally, which can mix the meat evenly, prevent the meat from sticking together, shorten the processing time, improve the pickling effect, and improve the taste of the meat by beating.

[0020] Furthermore, the rotating mechanism includes a pair of rotating rods arranged at the bottom of the support frame, a plurality of friction wheels arranged on the rotating rods, and a driving motor arranged on the support frame. The driving motor is transmission-connected to the pair of rotating rods through a chain, and the plurality of friction wheels are in frictional rolling contact with the outer wall of the rolling drum.

[0024] Furthermore, a vibration mechanism is also provided on the stirring rod, and the vibration mechanism includes a spring arranged at the bottom of the sleeve, the spring is against the right end of the stirring rod, a concave cylinder is provided at the left end of the stirring rod, a convex cylinder is provided in the rotating hole 1, the convex cylinder is engaged in the concave cylinder, a spiral tooth 1 is provided at the left end of the concave cylinder, and a spiral tooth 2 is provided at the right end of the convex cylinder, the spiral directions of the spiral tooth 1 and the spiral tooth 2 are opposite, and the tooth surfaces of the spiral tooth 1 and the spiral tooth 2 are against each other.

[0025] By adopting the above scheme, a vibration mechanism is set up, and spiral tooth one rotates relative to spiral tooth two, and the concave cylinder moves away from the convex cylinder and then approaches, in a continuous cycle, thereby driving the stirring rod to revolve around the tumbling cylinder and rotate while vibrating horizontally back and forth, so that the meat is not easy to stick to the stirring rod, and at the same time the stirring rod increases the breaking up effect of the meat.

[0026] Furthermore, a plurality of rollers are arranged in a ring array at the bottom of the tumbling and kneading drum, and the rollers are in frictional rolling contact with the support frame.

[0027] By adopting the above solution and arranging the rollers, when the tumbling and kneading drum rotates, part of the weight of the tumbling and kneading drum is transferred to the support frame through the rollers at the bottom, thereby reducing the load of the driving motor.

[0028] Furthermore, a plurality of annular rings are provided on the stirring rod.

[0029] By adopting the above solution, the annular ring is provided to increase the turning effect of the stirring rod on the meat.

[0030] Beneficial effects of the present invention:

The stirring rod rotates while the tumbling and kneading drum revolves, which can be evenly mixed to prevent meat from sticking, shorten processing time, improve pickling effect, and improve meat taste by beating.

[0032] 2. By setting a vibration mechanism, spiral tooth 1 rotates relative to spiral tooth 2, and the concave cylinder moves away from the convex cylinder and then approaches, in a continuous cycle, thereby driving the stirring rod to revolve around the tumbling cylinder and rotate while vibrating horizontally, so that the meat is not easy to stick to the stirring rod, and at the same time, the stirring rod increases the breaking effect of the meat.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0043] Example, see Figure 1-7 , is an embodiment of the present invention, and provides a meat tumbling and kneading device for food processing, comprising a base 1, and also comprising: a support frame 2, which is arranged above the base 1; a tumbling and kneading cylinder 3, which is arranged on the support frame 2, and its axis is in the horizontal direction; a rotating mechanism 4, which is arranged on the support frame 2 and in rolling contact with the cylinder wall of the tumbling and kneading cylinder 3, and is used to drive the tumbling and kneading cylinder 3 to rotate; a plurality of stirring rods 5, which are arranged and distributed on the inner wall of the tumbling and kneading cylinder 3 in a circular array along the axis of the tumbling and kneading cylinder 3, and are used to stir the meat; a rotation mechanism 6, which is arranged in the tumbling and kneading cylinder 3, connecting the stirring rod 5 and the tumbling and kneading cylinder 3, and is used to make the stirring rod 5 rotate while the tumbling and kneading cylinder 3 revolves; a tipping mechanism 7, which is arranged on the base 1, and is used to tilt the support frame 2 and the tumbling and kneading cylinder 3.

[0044] Specifically, there are three groups of stirring rods 5 arranged in a circular array along the axis of the tumbling and kneading drum 3. The stirring rods 5 intermittently stick to the inner wall of the tumbling and kneading drum 3 during rotation, so as to turn over the meat sticking to the inner wall of the drum. In addition, an opening is provided on one side of the tumbling and kneading drum 3, and a reversible drum cover is connected to the opening. A vacuum valve is provided on the drum cover, which can be connected to a vacuum machine to perform vacuum extraction in the tumbling and kneading drum 3, so as to increase the tumbling and kneading marinating effect on the meat.

[0045] By setting the rotating mechanism 4, the tumbling drum 3 is rotated along the axis of the drum to tumble and knead the meat in the drum; by setting the self-rotating mechanism 6, the stirring rod 5 is rotated along both ends of the stirring rod 5 while the drum rotates to stir the meat.

[0046] Reference Figure 2 and Figure 6 The left and right ends of the stirring rod 5 are horizontal rods 8, and the middle is a plurality of connected W-shaped curved rods 9.

[0047] The W-shaped curved rod 9 is provided in the middle of the stirring rod 5 to facilitate the use of the W-shaped curved rod 9 to break up the meat and prevent it from sticking together. The left and right ends are provided with horizontal rods 8 to ensure that the two ends of the stirring rod 5 rotate coaxially.

[0048] Reference Figure 2 and 5 The rotation mechanism 6 includes a partition plate 10 arranged at the bottom of the tumbling and kneading cylinder 3, a rotating hole 11 arranged at the open end of the tumbling and kneading cylinder 3, and a sleeve 12 arranged at the bottom of the tumbling and kneading cylinder 3. The left and right ends of the stirring rod 5 are rotatably arranged in the rotating hole 11 and the sleeve 12 respectively. The right end of the stirring rod 5 passes through the partition plate 10 and is rotatably connected to the partition plate 10. A support rod 13 is arranged on the support frame 2. The support rod 13 passes through the bottom of the tumbling and kneading cylinder 3 and does not exceed the partition plate 10. The axis of the support rod 13 coincides with the axis of the tumbling and kneading cylinder 3. A fixed gear 14 is fixedly connected to the support rod 13. The right end of the stirring rod 5 is connected to a rotating tooth 15 through a flat key, and the rotating tooth 15 is meshed with the fixed gear 14.

[0049] Specifically, the partition plate 10 divides the tumbling drum 3 into two chambers. The left chamber is used for tumbling meat, and a rotation mechanism 6 is arranged in the right chamber. The support rod 13 is fixedly connected to the support frame 2. The support rod 13 is rotatably connected to the bottom of the tumbling drum 3 through a sealed bearing. The right ends of the multiple stirring rods 5 are rotatably connected to the partition plate 10 through a sealed bearing. The rotating teeth 15 are sleeved on the right end of the stirring rod 5 through a flat key (not shown in the figure). The rotating teeth 15 rotate synchronously with the right end of the stirring rod 5 and can slide relative to the right end of the stirring rod 5. The three groups of rotating teeth 15 are respectively meshed with the fixed gear 14.

[0050] By setting the self-rotating mechanism 6, since the fixed gear 14 does not rotate when the tumbling and kneading drum 3 rotates, the tumbling and kneading drum 3 drives the rotating teeth 15 to revolve while the rotating teeth 15 mesh with the fixed gear 14. The rotating teeth 15 rotate and drive the stirring rod 5 to rotate. The stirring rod 5 rotates while the tumbling and kneading drum 3 revolves, which can be evenly mixed, prevent the meat from sticking, shorten the processing time, improve the pickling effect, and improve the taste of the meat by beating.

[0051] Reference Figure 2 and Figure 4 The rotating mechanism 4 includes a pair of rotating rods 16 arranged at the bottom of the support frame 2, a plurality of friction wheels 17 arranged on the rotating rods 16, and a driving motor 18 arranged on the support frame 2. The driving motor 18 is connected to the pair of rotating rods 16 through a chain 19, and the plurality of friction wheels 17 are in friction rolling contact with the outer wall of the tumbling cylinder 3.

[0052] Specifically, two groups of friction wheels 17 are arranged on each rotating rod 16, and the two groups of rotating rods 16 are fixedly connected to the support frame 2 through a bracket. Chain teeth are fixed on the driving motor 18 and the two groups of rotating rods 16, and the chain 19 is mounted on the chain teeth, so that the two groups of rotating rods 16 rotate synchronously, and the kneading cylinder 3 is driven to rotate through the friction between the friction wheel 17 and the wall of the kneading cylinder 3.

[0053] By providing the rotating mechanism 4, the plurality of friction wheels 17 drive the tumbling and kneading drum 3 to rotate, so as to tumble and knead the meat in the drum for pickling.

[0054] Reference Figure 2 and Figure 4 The tipping mechanism 7 includes a rotating frame 20 arranged on the base 1 and a hydraulic telescopic rod 21 arranged on the base 1. The rotating frame 20 is hinged to the side of the support frame 2, and the hydraulic telescopic rod 21 is hinged to the bottom of the support frame 2.

[0055] By setting the dumping mechanism 7, when the tumbling machine is rolling, the tumbling cylinder 3 is rotated at an upward angle, and after tumbling is completed, the tumbling cylinder 3 is rotated at a downward angle, so that the tumbled meat is easily dumped out from the cylinder mouth.

[0056] Reference Figure 3 and Figure 7 A vibration mechanism is also provided on the stirring rod 5, and the vibration mechanism includes a spring 22 arranged at the bottom of the sleeve 12, and the spring 22 is against the right end of the stirring rod 5. A concave cylinder 23 is provided at the left end of the stirring rod 5, and a convex cylinder 24 is provided in the rotating hole 11. The convex cylinder 24 is engaged in the concave cylinder 23. A spiral tooth 1 25 is provided at the left end of the concave cylinder 23, and a spiral tooth 2 26 is provided at the right end of the convex cylinder 24. The spiral directions of the spiral tooth 1 25 and the spiral tooth 2 26 are opposite, and the tooth surfaces of the spiral tooth 1 25 and the spiral tooth 2 26 are against each other.

[0057] Specifically, the concave cylinder 23 is fixed at the left end of the stirring rod 5, and the convex cylinder 24 is fixed at the bottom of the rotating hole 11. The spiral teeth 1 25 and the spiral teeth 2 26 are meshed with each other and have opposite spiral directions. When the stirring rod 5 rotates, the tooth surface of the spiral teeth 1 25 squeezes the tooth surface of the spiral teeth 2 26, so that the concave cylinder 23 is away from the convex cylinder 24. After the spiral teeth 1 25 rotates one circle, due to the squeezing of the left end of the stirring rod 5 by the spring 22, the spiral teeth 1 25 mesh with the spiral teeth 2 26 again, so that the concave cylinder 23 is close to the convex cylinder 24, and the cycle is continued, thereby driving the stirring rod 5 to vibrate horizontally back and forth.

[0058] By setting a vibration mechanism, the spiral tooth 1 25 rotates relative to the spiral tooth 2 26, and the concave cylinder 23 moves away from the convex cylinder 24 and then approaches it, in a continuous cycle, thereby driving the stirring rod 5 to revolve around the tumbling cylinder 3 and rotate while vibrating horizontally back and forth, so that the meat is not easily adhered to the stirring rod 5, and at the same time the stirring rod 5 increases the breaking effect of the meat.

[0059] Reference Figure 5A plurality of rollers 27 are arranged in a ring array at the bottom of the rolling and kneading cylinder 3 , and the rollers 27 are in frictional rolling contact with the support frame 2 .

[0060] By providing the roller 27 , when the tumbling and kneading drum 3 rotates, a part of the weight of the tumbling and kneading drum 3 is transferred to the support frame 2 through the roller 27 at the bottom, thereby reducing the load of the driving motor 18 .

[0061] Reference Figure 6 , a plurality of annular rings 28 are arranged on the stirring rod 5 .

[0062] By providing the annular ring 28, the turning effect of the stirring rod 5 on the meat is enhanced.

[0063] Working principle of the present invention:

[0064] When in use, first start the hydraulic telescopic rod 21 to shorten the telescopic rod, so that the opening of the tumbling and kneading cylinder 3 is at an upward angle, pour the meat into the cylinder, seal the cylinder cover, and use a vacuum machine to generate negative pressure in the cylinder, and start the drive motor 18. The drive motor 18 drives the two sets of rotating rods 16 to rotate in the same direction through the chain 19. The friction wheel 17 on the rotating rod 16 drives the tumbling and kneading cylinder 3 to rotate through friction with the cylinder wall of the tumbling and kneading cylinder 3; during the rotation of the tumbling and kneading cylinder 3, since the fixed gear 14 does not rotate when the tumbling and kneading cylinder 3 rotates, the rotating gear 15 meshes with the fixed gear 14, and the rotating gear 15 generates self-rotation and drives the stirring rod 5 to rotate, so that the stirring rod 5 rotates while the tumbling and kneading cylinder 3 revolves; at the same time, when the stirring rod 5 rotates, the tooth surface of the spiral tooth 1 25 squeezes the tooth surface of the spiral tooth 2 26, so that the concave cylinder 23 is away from the convex cylinder 24. After the spiral tooth 1 25 rotates one circle, due to the squeezing of the left end of the stirring rod 5 by the spring 22, the spiral tooth 1 25 meshes with the spiral tooth 2 26 again, so that the concave cylinder 23 is close to the convex cylinder 24, and the cycle continues, thereby driving the stirring rod 5 to revolve around the tumbling cylinder 3 and rotate while vibrating horizontally to mix evenly, ensuring that the meat and seasoning are more evenly mixed during the tumbling process, thereby improving product quality; shortening processing time, the turning of multiple stirring rods 5 can speed up the tumbling process, so that the meat can achieve the desired processing effect faster, shortening the overall production time; improving the pickling effect, adding stirring rods 5 can break up the adhered meat, increase the contact area between the meat and the seasoning liquid, make the pickling more complete, and improve the flavor; improving the taste of the meat, through reasonable stirring and beating, the meat can be promoted to become more tender and smooth, which helps to improve the taste of the final product.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
