Description

Technical Field

[0001] This invention relates to the field of food production technology, specifically to a fine homogenization and temperature-controlled mixing device and method for luncheon meat ingredients. Background Technology

[0002] The production of luncheon meat begins with carefully selected pork, a balanced ratio of lean to fat, which is then marinated separately. The lean meat is finely minced while the fat is coarsely minced, and then mixed with ice chips, starch, spices, and other ingredients to form a uniform paste. After vacuum mixing to remove air bubbles, the paste is filled into cans and sealed. It then undergoes high-temperature sterilization, strictly adhering to specific temperature and time procedures, and is cooled under back pressure to prevent can deformation. Finally, after tests for heat preservation and sealing, qualified products are labeled, packaged, and stored under suitable temperature and humidity conditions to ensure stable quality.

[0003] Mixing devices are required in the production of luncheon meat. For example, a mixing device and method for low-salt, high-calcium fish paste luncheon meat raw materials, published in application CN120132705A, is described. The mixing device includes a mixing container, which includes a mixing barrel and a top cover detachably mounted on the top surface of the mixing barrel. A power unit is fixedly installed on the top cover. A stirring structure extending downward into the mixing barrel is fixedly connected to the rotating shaft of the power unit. The stirring structure includes a rotating rod fixedly connected to the rotating shaft of the power unit and an electromagnet embedded in the rotating rod. An electrical signal interface is provided on the top cover and electrically connected to the top of the electromagnet. Several magnetic stirring shafts are also provided on the outer wall of the rotating rod. An anti-sticking frame is fitted on the bottom outer wall of the rotating rod, with its edge fitting against and slidingly connected to the inner wall of the mixing barrel. The magnetic stirring shafts are periodically self-cleaned by magnetic force, and the anti-sticking frame helps to remove the adhering substances from the inner wall of the mixing barrel.

[0004] The mixing process of luncheon meat involves two steps: first, low-speed mixing, followed by high-speed rotation for homogenization, ensuring even mixing of all components and improving taste and quality. During mixing, the friction between the blades and the raw materials generates heat. Existing methods involve external or bottom cooling to lower the temperature. However, for larger mixing tanks, the distance between the outer surface and the raw materials is significant, resulting in a still relatively high internal temperature even during rapid mixing. External cooling alone cannot effectively transfer the cooling effect to the interior of the raw materials for proper temperature control. Adding ice chips requires precise quantity control, a cumbersome process that hinders production efficiency. Summary of the Invention

[0013] A fine homogenization and temperature control method for lunch meat ingredients, comprising:

[0014] An appropriate amount of raw materials is obtained, after preliminary crushing, the raw materials are put into a stirring tank;

[0015] Low-speed stirring is carried out, the rotating speed is 300-500 rpm, the time is 4-6 min, the raw materials are fully mixed, and cold water is introduced into the disc-shaped cooling base and the spiral cooling jacket during stirring;

[0016] The flow rate of the cold water is controlled according to the temperature inside the stirring tank, and the temperature inside the stirring tank is kept at 4-13 DEG C;

[0017] High-speed homogenization is carried out, the rotating speed is 1000-1200 rpm, the time is 1-2 min, the shear force is increased, at the same time, the elastic rubber sleeve inside the stirring tank expands outward, the raw materials are extruded outward, and the direct cooling area of the raw materials is increased;

[0018] Speed reduction stirring is carried out, the rotating speed is 600-800 rpm, the time is 25-35 s, air bubbles are eliminated, and the meat paste is uniformly textured;

[0019] Discharging is carried out by gravity, and at the same time, ultra-low speed rotation is kept, the rotating speed is 0.5-1 rpm, so that the discharging is more thorough.

[0020] Compared with the prior art, the beneficial effects of the present application are:

[0021] Cold water is injected through the water inlet pipe, the cold water sequentially passes through the disc-shaped cooling base and the spiral cooling jacket, the materials inside the stirring tank are cooled, when fast stirring, the plurality of vertical rods are expanded outward through the adjusting mechanism, the materials are extruded outward through the elastic rubber sleeve, the materials are raised, so that the contact area of the materials with the side of the stirring tank is increased, and the cooling effect is improved, and when the rotating speed is low, the materials are ensured to be located at the bottom, and the stirring efficiency is improved.

[0022] Meanwhile, the counterweight is limited by the limiting rod, so that the counterweight can only approach or move away from the adjusting rod while following the rotation of the adjusting rod. When the rotating speed of the adjusting rod is low (low-speed stirring), the centrifugal force received by the counterweight is small, and the downward pulling force generated by the counterweight on the adjusting rod is not enough to expand the elastic rubber sleeve. When the rotating speed is high (high-speed homogenization), the rotating speed of the counterweight is increased, and the centrifugal force received by the counterweight is large. At this time, the counterweight moves outward and pulls the adjusting rod downward through the third connecting rod, thereby driving the vertical rod to spread outward, correlating the rotating speed with the expansion degree of the elastic rubber sleeve, and realizing the automatic adjustment effect.

[0023] Moreover, the rotating speed required for the elastic rubber sleeve to expand outward can be changed by adjusting the position of the threaded rod, so that the device can be used for stirring and homogenization of different raw materials, and the application range of the device is expanded.

[0024] In addition, after being connected with the gas supply device, gas can be injected into the elastic rubber sleeve through the air pipe to change the air pressure and make the elastic rubber sleeve expand. The elastic rubber sleeve between the vertical rods will partially protrude outward, and at this time, the raw material located in the gap between the vertical rods will be pushed out to participate in stirring or homogenization. Repeatedly reducing the air pressure inside the elastic rubber sleeve can prevent the raw material from adhering to the concave position on the surface and reduce the stirring dead angle.

[0025] In addition, during discharging, the right-angle block rises, and the stirred material can be discharged from the opening side of the right-angle block. The device can be rotated at an ultra-low speed at the same time of discharging, and the inclined blade will scrape the material at the bottom to the opening of the right-angle block. When the inclined blade contacts the right-angle block, it will move upward and pass over the right-angle block, so that the discharging is more thorough. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0039] As Figures 1-11As shown, the present application provides a technical solution: a fine homogenization and temperature control mixing device for lunch meat ingredients, comprising a stirring tank 1 internally provided with a temperature sensor, a disc-shaped cooling base 3 arranged at the bottom of the stirring tank 1, and a water inlet pipe connected to the side of the disc-shaped cooling base 3, a spiral cooling jacket 2 arranged at the side of the stirring tank 1, the bottom of the spiral cooling jacket 2 being in communication with the disc-shaped cooling base 3, and a water outlet pipe arranged at the upper end side of the spiral cooling jacket 2, a support 4 arranged below the disc-shaped cooling base 3, a cover body 5 arranged at the upper end of the stirring tank 1, a feed hopper 39 connected to the cover body 5, a discharge port 6 connected to the lower end of the stirring tank 1, a rotating rod 7 rotatably arranged at the bottom of the stirring tank 1, and a drive motor 8 arranged below the stirring tank 1 for driving the rotating rod 7 to rotate, an adjusting rod 9 rotatably arranged in the middle of the cover body 5, a plurality of circumferentially distributed vertical rods 10 arranged on the outer side of the adjusting rod 9 and the rotating rod 7, an elastic rubber sleeve 12 connected to the inner side of the vertical rod 10, and an adjusting mechanism arranged on the inner side of the vertical rod 10 for adjusting the diffusion degree of the vertical rod 10, and a plurality of inclined stirring blades 11 arranged on the outer side of the vertical rod 10, and the height of the inclined stirring blades 11 on each vertical rod 10 gradually decreases along the circumferential direction.

[0040] It should be noted that cold water is injected through the water inlet pipe, and the cold water sequentially passes through the disc-shaped cooling base 3 and the spiral cooling jacket 2, thereby cooling the bottom and side of the material inside the stirring tank 1, and the flow rate of the cold water is controlled according to the value of the temperature sensor to ensure that the temperature inside the stirring tank 1 is stable. During the stirring process, the drive motor 8 drives the rotating rod 7 to rotate, thereby driving the plurality of vertical rods 10 to rotate along the central axis of the rotating rod 7, and the stirring effect is achieved through the plurality of inclined stirring blades 11. Moreover, when rapid stirring is required, the adjusting mechanism can be used to expand the plurality of vertical rods 10 outward, and the elastic rubber sleeve 12 can be used to extrude the material outward, so that the material is raised, thereby increasing the contact area between the material and the side of the stirring tank 1, thereby improving the cooling effect. At low speed, the material is ensured to be located at the bottom, thereby improving the stirring efficiency. At high speed, the area of the material directly contacting the cooling surface is increased, thereby improving the cooling efficiency and the temperature control during the homogenization process. The internal flow channel of the disc-shaped cooling base 3 is as shown in Figure 4 The cross section of the spiral cooling jacket 2 is as shown in Figure 3 Both of them are existing structures, and the specific principles will not be described again.

[0041] As shown in Figures 5-7 and Figure 10As shown, the inner side of the vertical rod 10 is provided with a mounting rod 13, the elastic rubber sleeve 12 is sleeved on the outer side of the mounting rod 13, and the vertical rod 10 is fixed on the outer side of the elastic rubber sleeve 12, the upper end of the mounting rod 13 is hinged with two parallel first connecting rods 14, and the other end of the first connecting rod 14 is hinged with the adjusting rod 9, the bottom of the mounting rod 13 is hinged with a second connecting rod 15, and the other end of the second connecting rod 15 is hinged with the rotating rod 7, the rotating rod 7 is provided with a convex ring 16, the bottom of the elastic rubber sleeve 12 is fixed on the outer side of the convex ring 16, and the adjusting rod 9 is fixed with a baffle 17, and the upper end of the elastic rubber sleeve 12 is fixed on the outer side of the bottom of the baffle 17.

[0042] It should be noted that the two ends of the elastic rubber sleeve 12 are sealed by the convex ring 16 and the baffle 17, which can ensure that the stirring raw materials are outside the elastic rubber sleeve 12, easy to clean, the mounting rod 13 is limited by the two parallel first connecting rods 14, which can keep the vertical state, when the adjusting rod 9 is lowered, the mounting rod 13 and the vertical rod 10 can be pushed outwards through the two first connecting rods 14, so as to expand the elastic rubber sleeve 12, the structure is stable, and the adjustment is convenient.

[0043] As shown in Figure 8 The adjusting mechanism includes a shell 18 fixed on the cover 5, a plurality of circumferentially distributed counterweights 19 are arranged on the inner side of the shell 18, and a third connecting rod 20 is hinged on the inner side of the counterweight 19, the other end of the third connecting rod 20 is hinged with the upper end of the adjusting rod 9, a limiting rod 21 is arranged on the inner side of the counterweight 19, a avoiding slot is formed in the middle position of the limiting rod 21, and the third connecting rod 20 passes through the avoiding slot, a plurality of limiting grooves 22 are formed on the adjusting rod 9, and the limiting rod 21 passes through the limiting grooves 22, and the limiting rods 21 connected on the plurality of counterweights 19 are different in height.

[0044] It should be noted that the counterweight 19 is limited by the limiting rod 21, so that the counterweight 19 can only move close to or away from the adjusting rod 9 while following the rotation of the adjusting rod 9, when the rotating speed of the adjusting rod 9 is low (low speed stirring), the centrifugal force of the counterweight 19 is small, at this time, the downward pulling force of the counterweight 19 on the adjusting rod 9 is not enough to expand the elastic rubber sleeve 12, when the rotating speed is high (high speed homogenization), the rotating speed of the counterweight 19 is increased, and the centrifugal force is large, at this time, the counterweight 19 moves outward and pulls the adjusting rod 9 downward through the third connecting rod 20, thereby driving the vertical rod 10 to spread outward.

[0045] As shown in Figure 9As shown, the weight block 19 outside is fixed with mounting block 23, mounting block 23 hinged with two support frame 24, and mounting block 23 is fixed with limit block 27, the outer end of support frame 24 is rotatably connected with the roller 25, and the roller 25 is in contact with the inner wall of the shell 18, the support frame 24 is rotatably provided with the adjusting plate 28, the adjusting plate 28 is provided with a through hole, and the threaded rod 29 is inserted in the through hole, the threaded rod 29 is connected with the fixed nut, and the fixed nut is in contact with the adjusting plate 28, which is used to fix the threaded rod 29, one end of the threaded rod 29 is provided with a hook, and the two hooks are connected with the tension spring 26.

[0046] It should be noted that the two support frames 24 are pulled tight by the tension spring 26, and at this time the elastic rubber sleeve 12 is in a contracted state, when the adjusting rod 9 rotates, the weight block 19 moves outward, which will open the two support frames 24, so it not only needs to overcome the elastic force of the elastic rubber sleeve 12 itself, but also needs to overcome the tension of the tension spring 26, and the length of the threaded rod 29 can be adjusted by the nut, so as to change the initial length of the tension spring 26 and the tension of the tension spring 26, so the position of the threaded rod 29 can be adjusted to change the rotating speed required for the elastic rubber sleeve 12 to expand outward, so as to use different raw materials for stirring and homogenization, and expand the application range of the device.

[0047] As shown in the figure, Figure 8 The middle position of the adjusting rod 9 is provided with a through hole, and the air pipe 30 is inserted in the through hole, and the air pipe 30 is rotatably connected with the adjusting rod 9.

[0048] It should be noted that after connecting with the gas supply device, the air pipe 30 is in a fixed state, and gas can be injected into the elastic rubber sleeve 12 through the air pipe 30 to change the gas pressure and make the elastic rubber sleeve 12 expand, and the elastic rubber sleeve 12 between the vertical rods 10 will partially protrude outward, at this time the raw materials located in the gap between the vertical rods 10 will be pushed out to participate in stirring or homogenization, repeatedly reducing the gas pressure in the elastic rubber sleeve 12 can prevent the raw materials from adhering to the surface of the concave position, and reduce the stirring dead angle.

[0049] As shown in the figure, Figure 10 The outer side of the rotating rod 7 is slidably provided with a lifting ring 31, the outer side of the lifting ring 31 is provided with a plurality of inclined blades 32, the upper edge of the inclined blade 32 is a knife edge, and the lower edge is in contact with the bottom of the stirring tank 1, the spring 33 is sleeved on the rotating rod 7, which is used to press the lifting ring 31 downward.

[0050] It should be noted that when stirring at low speed, the inclined blade 32 can be in contact with the bottom of the stirring tank 1 to prevent the raw materials at the bottom from not participating in stirring, and when homogenizing at high speed, the inclined blade 32 rotates at high speed and is lifted upward (due to the inclined distribution of the inclined blade 32, it is subjected to the upward reaction force of the raw materials), at this time no friction force is generated, the wear is reduced, and the cutting of the inclined blade 32 improves the homogenization effect.

[0051] As shown in Figure 11 the inner side of the discharge port 6 is slidingly provided with a right-angle block 34, vertical slots 35 are formed on both sides of the discharge port 6, and lifting plates 36 are provided on the outer sides of the vertical slots 35. Connection pieces 37 are slidingly provided in the vertical slots 35, and the inner sides of the connection pieces 37 are connected with the right-angle block 34, and the outer sides of the connection pieces 37 are connected with the lifting plates 36. A pneumatic cylinder 38 is installed on the outer side of the discharge port 6, and the end of the pneumatic cylinder 38 is connected with the lifting plate 36.

[0052] It should be noted that during the stirring and homogenization process, the upper end of the right-angle block 34 blocks the raw materials to prevent the material from being exposed. When discharging, the pneumatic cylinder 38 drives the lifting plate 36 to rise, at this time the right-angle block 34 rises synchronously, and the stirred material can be discharged from the opening side of the right-angle block 34. Moreover, ultra-low speed rotation can be performed at the same time of discharging, and the inclined blade 32 will scrape the material at the bottom to the opening of the right-angle block 34. When the inclined blade 32 contacts the right-angle block 34, it will move upward and pass over the right-angle block 34, so that the discharging is more thorough.

[0056] The flow rate of the cold water is controlled according to the internal temperature of the stirring tank, and the internal temperature of the stirring tank is maintained at 4-13℃;

[0057] High-speed homogenization is performed, the speed is 1000-1200 rpm, and the time is 1-2 min, the shear force is increased, and at the same time the elastic rubber sleeve on the inside of the stirring tank expands outward, extruding the raw materials outward to increase the direct cooling area of the raw materials;

[0058] Speed reduction stirring is performed, the speed is 600-800 rpm, and the time is 25-35 s, to eliminate bubbles and uniform the texture of the meat paste;
