Description

Technical Field

[0001] The invention relates to the technical field of food processing equipment, in particular to a continuous tumbling and kneading machine for processing cured pig's feet. Background Art

[0002] In the processing of cured pork feet and other meat products, pickling is a crucial process, which directly affects the taste and quality of the final product. In order to improve the pickling effect, tumbling machines are widely used in this field.

[0003] The traditional tumbling machine for processing cured pig's feet mainly consists of three parts: a pickling tank, a driving device and a vacuum machine. A spiral flip plate is usually set inside the pickling tank, which is used to mix the product in the tank with the marinade better under the drive of the driving device. The specific operation is: put the product into the pickling tank, then close the sealing cover, use the vacuum machine to extract the pickling tank into a vacuum state, turn on the driving device, and make the product flip up and down in the pickling tank, collide and hit each other, so that the product can better absorb the marinade through physical impact. After pickling, the valve on the sealing cover is used to restore the normal pressure in the pickling tank, and finally remove the sealing cover to take out the product.

[0004] However, in the long-term use process, the existing tumble kneading machine has exposed some significant disadvantages:

[0005] 1. Low production efficiency: Since the products need to be put in and taken out through the opening of the pickling tank, the tumbler cannot work continuously. Each time the product is put in, the air in the pickling tank needs to be extracted by a vacuum machine to achieve a vacuum state, which takes a certain amount of time. Similarly, after pickling, it takes a certain amount of time for the pickling tank to return to normal pressure. These two processes together extend the pickling time of a single tank of product, thereby reducing production efficiency;

[0006] 2. Poor pickling effect: Traditional tumblers rely on the inner wall of the pickling tank and the spiral flip plate to generate physical impact force. However, when there are a large number of products in the pickling tank, the interaction force between the products will increase, resulting in a significant weakening of the impact force of the beating. This not only affects the pickling effect of the product, but may even require a longer pickling time to achieve the desired quality. In addition, this drawback also limits the production capacity of a single tank, further reducing the production efficiency of the tumbler.

[0007] In summary, the existing tumbling and kneading machines for processing cured pig's feet have obvious shortcomings in production efficiency and pickling effect. To this end, we propose a continuous tumbling and kneading machine for processing cured pig's feet. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides a continuous tumbling machine for processing cured pig's feet, comprising a support platform, on which a fixed seat is relatively installed, and the fixed seat is rotatably connected with a bearing, and a pickling cylinder is rotatably arranged in the bearing, and both ends of the pickling cylinder are conical, and further comprising:

The first valve and the third valve are in the same open or closed state, the second valve and the fourth valve are in the same open and closed state, and the first valve and the second valve are in opposite open or closed states.

The first extrusion rod and the first extrusion cylinder and the second extrusion cylinder on the adjacent second extrusion rod are arranged oppositely.

[0017] The squeezing auxiliary mechanism is installed inside the pickling cylinder and is connected to the supporting mechanism, the first squeezing rod and the second squeezing rod. When the spiral scooping plate rotates, the squeezing auxiliary mechanism synchronously drives the first squeezing rod and the second squeezing rod to rotate in the opposite direction, thereby preventing the product from sticking and squeezing the product at the same time.

[0019] In some embodiments, the support mechanism includes a first sealing ring installed between a T-shaped tee and one end of the pickling barrel discharge port, the horizontal opening of the T-shaped tee and one end of the pickling barrel in the corresponding direction are rotatably connected to the first sealing ring, the inner wall of the first sealing ring is fixedly connected to the end corresponding to the spiral scooping plate, a support plate is fixed at a position in the pickling barrel away from the T-shaped tee, the support plate is annular and has an L-shaped cross-section, an anti-flow groove is opened in the pickling barrel, the anti-flow groove is located between the support plate and the pickling barrel feed port, a second sealing ring is installed on the support plate, the inner wall of the second sealing ring is fixedly connected to the end corresponding to the spiral scooping plate, the second sealing ring is rotatably connected to the support plate and the anti-flow groove, and the cross-sections of the first sealing ring and the second sealing ring are both "I"-shaped.

One end of the first extrusion cylinder and the second extrusion cylinder passes through the support plate and is located in the chamber formed between the support plate and the pickling cylinder, and the other side passes through the sealed cover and is located inside the sealed cover. A second gear ring is sleeved on the second sealing ring, and a second gear is fixed on the end of a portion of the first extrusion rod close to the support plate. The second gear and the second gear ring are meshed with each other. A third gear is installed at the end of the first extrusion rod located in the sealed cover, and a fourth gear is installed at the end of the second extrusion rod located in the sealed cover. The gear diameter of the third gear is larger than that of the fourth gear, and they are meshed with each other.

[0022] In some embodiments, the minimum distance between the two first extrusion cylinders in opposite positions is equal to the maximum outer diameter of the spiral lifting plate.

[0023] In some embodiments, the first extrusion cylinder and the second extrusion cylinder are equal in length and are 5-20 cm in length.

[0028] 3. The first extrusion cylinder and the second extrusion cylinder have different diameters and are arranged in a staggered manner, so that the first extrusion cylinders are protruding one by one in the marinating cylinder. When the product falls onto the first extrusion cylinder, the pressure on the contact part between the product and the first extrusion cylinder increases, which is conducive to the penetration of the marinade;

[0029] 4. The rotation of the first extrusion cylinder and the second extrusion cylinder in opposite directions can prevent the product from sticking to the first extrusion cylinder and the second extrusion cylinder, and the force generated by mechanical extrusion is conducive to the marinade penetrating into the interior of the product.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1:

[0042] A feed pipe 2, which is fixed on the support platform 1 through a support rod and is L-shaped, one end of which is rotatably connected to one end of the pickling cylinder 13, and a first valve 21 and a second valve 22 are respectively provided on the feed pipe 2;

[0043] T-shaped tee 3, the T-shaped tee 3 is fixed on the support platform 1 through a support frame, and is located on both sides of the pickling cylinder 13 with the feed pipe 2 respectively. The opening of the T-shaped tee 3 in the horizontal direction is coaxial with the other end of the pickling cylinder 13, and the upper opening in the vertical direction is installed with a sealing joint 33, which is connected to the vacuum system. The lower part of the T-shaped tee 3 in the vertical direction is respectively provided with a third valve 31 and a fourth valve 32. The first valve 21, the second valve 22, the third valve 31, and the fourth valve 32 are all electrically controlled valves, and are electrically connected to each other. The opening or closing state between the first valve 21 and the third valve 31 is the same, the opening and closing state between the second valve 22 and the fourth valve 32 is the same, and the opening or closing state between the first valve 21 and the second valve 22 is opposite. The four valves cooperate with each other to drive the pickling cylinder 13 to be in a vacuum state all the time. Those skilled in the art only need to realize the coordinated control of the above valves through simple programming, and this technology belongs to the scope of the prior art;

[0044] A driving mechanism 4, which is mounted on the support platform 1 and connected to the pickling cylinder 13, and drives the pickling cylinder 13 to rotate;

[0045] A spiral scooping plate 5, which is arranged inside the pickling cylinder 13;

[0046] The supporting mechanism 6 is installed on the spiral scooping plate 5 and connected with the T-shaped tee 3 and the pickling cylinder 13. The supporting mechanism 6 supports the spiral scooping plate 5 and connects the horizontal opening of the T-shaped tee 3 with one end of the pickling cylinder 13 close to the T-shaped tee 3;

[0047] The linkage mechanism 7 is installed on the support platform 1 and connected to the pickling cylinder 13 and the support mechanism 6. When the driving mechanism 4 drives the pickling cylinder 13 to rotate, the linkage mechanism 7 cooperates with the support mechanism 6 to drive the spiral shovel 5 to rotate in the opposite direction of the pickling cylinder 13 through the rotation force of the pickling cylinder 13;

[0048] A first extrusion rod 81, wherein the first extrusion rod 81 is provided in a plurality and arranged in a circular array inside the pickling cylinder 13, wherein a first extrusion cylinder 811 and a second extrusion cylinder 812 are sleeved on the first extrusion rod 81, and the first extrusion cylinder 811 and the second extrusion cylinder 812 are arranged alternately;

[0049] The second extrusion rods 82 are the same in number as the first extrusion rods 81 and are arranged in a circular array inside the pickling cylinder 13 and staggered with the first extrusion rods 81. The second extrusion rods 82 are also sleeved with the first extrusion cylinder 811 and the second extrusion cylinder 812. The first extrusion rod 81 and the first extrusion cylinder 811 and the second extrusion cylinder 812 on the adjacent second extrusion rod 82 are arranged oppositely.

[0050] The squeezing auxiliary mechanism 9 is installed inside the pickling cylinder 13 and is connected to the supporting mechanism 6, the first squeezing rod 81, and the second squeezing rod 82. When the spiral scooping plate 5 rotates, the squeezing auxiliary mechanism 9 synchronously drives the first squeezing rod 81 and the second squeezing rod 82 to rotate in the opposite direction, thereby preventing the product from sticking and squeezing the product.

[0051] The driving mechanism 4 includes a motor 41 installed on the support platform 1, a first double-row sprocket 42 is installed on the driving shaft of the motor 41, a second double-row sprocket 43 is sleeved on one end of the pickling cylinder 13 close to the feed pipe 2, and the first double-row sprocket 42 and the second double-row sprocket 43 are connected by a first chain 44.

[0052] The power of the subsequent support mechanism 6 and the extrusion auxiliary mechanism 9 is derived from the transmission of the motor 41 through the first double-row sprocket 42 and the second double-row sprocket 43. Compared with the traditional sprocket, the double-row sprocket can make the force transmission more stable. At the same time, the force exerted on the double-row sprocket is more dispersed, which has a positive effect on the long-term use of the equipment.

[0053] The supporting mechanism 6 includes a first sealing ring 61 installed between the T-shaped tee 3 and one end of the discharge port of the pickling cylinder 13. The horizontal opening of the T-shaped tee 3 and one end of the pickling cylinder 13 in the corresponding direction are rotatably connected to the first sealing ring 61. The inner wall of the first sealing ring 61 is fixedly connected to the end corresponding to the spiral scooping plate 5. A supporting plate 62 is fixed at a position away from the T-shaped tee 3 in the pickling cylinder 13. The supporting plate 62 is annular and has an L-shaped cross-section. An anti-flow groove 63 is opened in the pickling cylinder 13. The anti-flow groove 63 is located between the supporting plate 62 and the feed port of the pickling cylinder 13. A second sealing ring 64 is installed on the supporting plate 62. The inner wall of the second sealing ring 64 is fixedly connected to the end corresponding to the spiral scooping plate 5. The second sealing ring 64 is rotatably connected to the support plate 62 and the anti-flow groove 63. The cross-sections of the first sealing ring 61 and the second sealing ring 64 are both in the shape of an "I".

[0054] The linkage mechanism 7 includes a first sprocket 71 sleeved on one end of the pickling cylinder 13 near the T-shaped tee 3, a fixed block 72 is installed on the support platform 1, there are two fixed blocks 72, and they are connected by a rotating shaft 73, a second sprocket 74 is sleeved on the rotating shaft 73, a second chain 75 is connected between the first sprocket 71 and the second sprocket 74, a first gear ring 76 is sleeved on the first sealing ring 61, a first gear 77 is sleeved on the rotating shaft 73, and the first gear 77 and the first gear ring 76 are meshed with each other.

[0055] The extrusion auxiliary mechanism 9 includes a sealed cover 91 installed in the pickling cylinder 13. The sealed cover 91 is annular and is located on the side opposite to the support plate 62. One end of the first extrusion cylinder 811 and the second extrusion cylinder 812 passes through the support plate 62 and is located in the chamber formed between the support plate 62 and the pickling cylinder 13. The other side passes through the sealed cover 91 and is located inside the sealed cover 91. A second gear ring 92 is sleeved on the second sealing ring 64. A second gear 93 is fixed on one end of a portion of the first extrusion rod 81 close to the support plate 62. The second gear 93 and the second gear ring 92 are meshed with each other. A third gear 94 is installed at one end of the first extrusion rod 81 located in the sealed cover 91, and a fourth gear 95 is installed at one end of the second extrusion rod 82 located in the sealed cover 91. The gear diameter of the third gear 94 is larger than that of the fourth gear 95, and they are meshed with each other.

[0056] The minimum distance between the two first extrusion cylinders 811 in relative positions is equal to the maximum outer diameter of the spiral lifting plate 5, ensuring that the spiral lifting plate 5 can synchronously turn over the products in the pickling cylinder 13.

[0057] The working principle of the present invention is as follows: the staff puts the marinade and the product inside the marinating cylinder 13, and through the cooperation of the vacuum system and the sealing joint 33, the marinating cylinder 13 is evacuated to a vacuum state, and the motor 41 is turned on. The motor 41 drives the marinating cylinder 13 to rotate through the first double-row sprocket 42, the first chain 44, and the second double-row sprocket 43. During the rotation of the marinating cylinder 13, the first extrusion rod 81 and the second extrusion rod 82 in the annular array are driven to rotate coaxially with themselves through the support plate 62 and the sealing cover 91. At this time, the first extrusion rod 81 and the second extrusion rod 82 drive their respective corresponding first extrusion cylinders 811 and second extrusion cylinders 812 to perform the same action;

[0058] The different diameters and staggered layout of the first extrusion cylinder 811 and the second extrusion cylinder 812 make the first extrusion cylinder 811 protrude one by one in the pickling cylinder 13. The shape of the first extrusion cylinder 811 and the second extrusion cylinder 812 after coordination is similar to a cylinder with a plurality of convex points on the inner wall. During the rotation of the pickling cylinder 13, the first extrusion rod 81, the second extrusion rod 82 and the corresponding first extrusion cylinder 811 and the second extrusion cylinder 812 drive the product to flip over simultaneously. When the product flips upside down and hits the first extrusion cylinder 811, due to the reduction of the force-bearing area, the part of the product in contact with the first extrusion cylinder 811 will be subjected to a stronger pressure, so that the muscles and cells of the product are physically destroyed with a stronger force, which is conducive to the penetration of the marinade. At the same time, the uneven layout can effectively improve the flipping efficiency of the product when driving the product to flip, so that the product can be marinated more evenly.

[0059] When the pickling cylinder 13 rotates, the first sprocket 71 near one end of the T-shaped tee 3 is driven to rotate. The first sprocket 71 drives the first gear 77 to rotate through the second chain 75, the second sprocket 74, and the rotating shaft 73. The first gear 77 drives the first gear ring 76 to rotate in the opposite direction. The first gear ring 76 drives the spiral shovel 5 to rotate through the first sealing ring 61, that is, the spiral shovel 5 and the pickling cylinder 13 rotate in the opposite direction. After the product moves to a certain height through the spiral shovel 5, it falls downward under the action of its own gravity, breaks away from the spiral shovel 5, and contacts with the first extrusion cylinder 811 and the second extrusion cylinder 812. If the first extrusion cylinder 811 and the second extrusion cylinder 812 drive the product to move clockwise, the spiral shovel 5 applies a counterclockwise force to the product. When the product contacts the spiral shovel 5 again, a greater impact force will be generated, and the subsequent extrusion force on the product will also be greater, which is conducive to the penetration of the marinade into the product.

[0060] The spiral lifting plate 5 rotates while driving the second sealing ring 64 to rotate. The second sealing ring 64 drives the first extrusion rod 81 to rotate through the second gear ring 92 and the second gear 93. The first extrusion rod 81 drives the remaining first extrusion rods 81 and second extrusion rods 82 to rotate through the third gear 94 and the fourth gear 95. Since the adjacent first extrusion rods 81 and the second extrusion rods 82 rotate in opposite directions, the extrusion force on the product is further increased, and the marinade is assisted to better penetrate into the product. At the same time, the different diameters of the third gear 94 and the fourth gear 95 will produce a differential speed, which, on the one hand, prevents the product from sticking to the first extrusion cylinder 811 or the second extrusion cylinder 812, and on the other hand, is conducive to the irregular movement of the marinade and the product in the marinating cylinder 13, which facilitates the uniform penetration of the marinade.

[0061] After the product is marinated, the first valve 21 is opened, the third valve 31 is opened synchronously, and the second valve 22 and the fourth valve 32 are closed. At this time, as the spiral lifting plate 5 continues to rotate, the product falls between the third valve 31 and the fourth valve 32. At this time, since the first valve 21 is in an open state, the unmarinated product is added to the feed pipe 2, and part of the marinade is added. The newly added product and the marinade mixture will fall between the first valve 21 and the second valve 22, and then the second valve 22 is opened. At this time, the fourth valve 32 is opened synchronously, and the first valve 21 and the third valve 32 are closed. 31 is closed, and with the opening of the fourth valve 32, the marinated products between the third valve 31 and the fourth valve 32 are discharged from the T-shaped tee 3, and the staff can place a collecting device at the bottom of the T-shaped tee 3. After the second valve 22 is opened, the product and marinade mixture between the first valve 21 and the second valve 22 are smoothly added to the marinating cylinder 13. The first valve 21 and the third valve 31 ensure that the marinating cylinder 13 is in a vacuum state. The equipment can marinate the products continuously. Compared with the traditional tumbling machine, it is more efficient and has a better marinating effect.

[0062] Embodiment 2:

[0063] Based on Example 1, the present invention further optimizes this solution:

[0064] The first extrusion cylinder 811 and the second extrusion cylinder 812 are equal in length and are 5-20 cm in length.

[0065] Enterprises can select the first extrusion cylinder 811 and the second extrusion cylinder 812 of appropriate length according to the processed products, so that the present equipment has a wider application scenario. For products with larger volume, the first extrusion cylinder 811 and the second extrusion cylinder 812 with longer length are selected. The longer length has lower cost in parts production and better final product completion. For products with smaller volume, the first extrusion cylinder 811 and the second extrusion cylinder 812 with shorter length are selected, so that the marinade has good penetration effect and better marinating effect.

[0066] The length of the first extrusion cylinder 811 and the second extrusion cylinder 812 is 5 cm.

[0067] In this application, according to the actual volume of pig's feet and a large number of experiments, when the first extrusion cylinder 811 and the second extrusion cylinder 812 are both 5 cm, the pickling effect of pig's feet is best. Compared with the transmission tumbling machine, the efficiency of this equipment is also greatly improved.

[0068] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
