Abstract
Description
Technical Field
[0001] This invention relates to the field of dairy product production and processing technology, specifically to a dairy product production and processing equipment with temperature control function. Background Technology
[0002] In the process of making condensed milk into dessert toppings, fresh milk and sucrose need to be mixed and heated in a mixing tank in the appropriate proportion. The temperature should be controlled between 60 and 80 degrees Celsius. When the temperature exceeds 85 degrees Celsius, a gelatinization reaction will occur.
[0003] In existing dairy mixing tanks, a heat transfer medium is introduced into the heating chamber during the heating process to heat the dairy products inside and produce condensed milk. However, because the heat transfer medium in the heating chamber cannot directly contact the dairy products, but instead transfers heat through an intermediate metal layer, the temperature of the heat transfer medium needs to exceed the set temperature to quickly raise the temperature of the dairy products to the desired temperature. This can easily lead to a lag. If the temperature of the dairy products reaches the set temperature but the temperature of the heat transfer medium cannot be reduced in time, it can easily cause a gelatinization reaction in the dairy products, thus affecting the quality of the condensed milk product. Furthermore, since the heat transfer medium is injected from the bottom, the heat at the bottom is usually significantly higher than that at the top. In addition, high-density components tend to continuously settle and accumulate during the refining process, which can easily cause gelatinization at the bottom of the mixing tank where the dairy products are in contact, forming solids that adhere to the bottom of the mixing tank. If these solids are not cleaned in time before they harden and clump together, the gelatinization will be intensified, causing the condensed milk product to fail.
[0004] Therefore, a dairy product production and processing equipment with temperature control function is proposed. Summary of the Invention
[0005] The purpose of this invention is to provide a dairy product production and processing equipment with temperature control function to solve the problems raised in the prior art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a dairy product processing equipment with temperature control function, comprising a mixing tank, a feed inlet, a discharge outlet, a motor, a shaft, stirring blades, a heating chamber, a heat medium inlet, a heat medium outlet, a temperature control component, a scraping component, and a conveying component; the feed inlet is located at the top of the mixing tank, the discharge outlet is located at the bottom of the mixing tank, the motor is located at the top of the mixing tank, the shaft is located on the central axis of the mixing tank and fixedly connected to the output shaft of the motor, two sets of stirring blades are provided and fixedly connected to the shaft, and the two sets of stirring blades are respectively located near the middle and near the top of the shaft, the heating chamber is located on the outside of the mixing tank and surrounds the mixing tank, the heat medium inlet and the heat medium outlet are both located at the bottom of the heating chamber, the temperature control component is located on the outer wall of the mixing chamber, the scraping component is located at the bottom end of the shaft and contacts the inner bottom wall of the mixing tank, and the conveying component is located at the top of the shaft and moves up and down reciprocating with the rotation of the shaft; in use When the motor starts, it drives the shaft and stirring blades to rotate inside the mixing vessel, thus stirring the dairy products inside. Simultaneously, the heating medium enters the heating chamber from the heating medium inlet and exits from the heating medium outlet, continuously circulating to heat the dairy products inside the mixing vessel. The dairy raw materials are gradually transformed into condensed milk during heating and stirring. When the temperature of the heating medium is too high, causing the temperature inside the mixing vessel to exceed the set temperature, the temperature control component will activate the liquid cooling circulation to cool down. At the same time, it can automatically control the motor speed to increase, thereby accelerating the stirring rate of the dairy products. During the stirring process, the scraping component can adhere to the bottom of the mixing vessel for stirring, preventing the bottom temperature from becoming too high and causing the surface to gelatinize and clump. When the temperature rises rapidly and encounters clumps, the scraping component pushes the clumps upward as it passes over them. Furthermore, the scraping component's resistance to the bottom of the mixing vessel gradually increases as the shaft speed increases. While the shaft rotates, the conveying component can draw the liquid dairy products above the mixing vessel to the bottom, further ensuring the uniformity of stirring.
[0007] Preferably, the discharge port is located at the bottom center axis of the mixing vessel, and the shaft and the liquid outlet are on the same axis; when the conveying assembly is working, the liquid discharged from the shaft can just impact the depression formed by the discharge port, preventing the sediment in the dairy liquid from depositing here.
[0008] Preferably, the temperature control component includes a gas valve, a pressure pipe, a piston, a fixing ring, an elastic element, and a cooling element. The gas valve passes through the heating chamber and is connected to the stirred tank, and is located at the top of the stirred tank. The pressure pipe is fixedly connected to the outer wall of the heating chamber, and the pressure pipe and the gas valve are connected by a metal pipe. The piston is slidably connected to the pressure pipe, the fixing ring is fixedly connected to the top of the pressure pipe, the elastic element is located between the fixing ring and the piston, and the cooling element is located above the pressure pipe. When the temperature inside the stirred tank is too high, the gas pressure will also increase, and the high-pressure gas will be discharged from the gas valve and then enter the pressure pipe through the metal pipe, pushing the piston upward against the thrust of the elastic element. When the temperature returns to normal, the elastic element will push the piston downward.
[0009] Preferably, the cooling component includes a water inlet pipe, a sliding cavity, a sliding tube, a water inlet hole, a threaded pipe, a flexible hose, and a push rod. The water inlet pipe is fixedly connected to the outer wall of the heating cavity. The sliding cavity is fixedly connected to the bottom of the water inlet pipe and communicates with it. The top of the sliding tube extends into the water inlet pipe and is slidably connected to the sliding cavity. Multiple sets of water inlets are provided and vertically opened on the sliding tube. The threaded tube is spirally wound around the outside of the stirring vessel and located inside the heating cavity. The threaded tube and the sliding tube are connected by a flexible hose. The push rod is fixedly connected to the top of the piston, and the top of the push rod is fixedly connected to the bottom of the sliding tube. As the temperature of the stirring vessel continues to rise, the gas pressure will also continue to increase, and then gradually... The rising piston will gradually push the sliding tube upwards in the inlet pipe through the push rod. During the upward movement, the water inlet holes on the sliding tube will gradually be exposed in the sliding cavity. Therefore, the coolant in the inlet pipe connected to the external coolant storage tank will enter the sliding tube through the water inlet holes, and finally enter the threaded pipe through the hose to complete the circulation before being discharged to the external coolant storage tank. This will cool down the heat medium in the heating chamber and prevent the heat medium from continuing to heat the dairy products in the stirring vessel. As the temperature and air pressure in the stirring vessel increase, the piston will push the sliding tube upwards a greater distance, and more water inlet holes will be exposed in the inlet pipe. Therefore, the flow rate of coolant entering the threaded pipe will be greater.
[0010] Preferably, a control seat for controlling the motor speed is fixedly connected to the outside of the sliding cavity. A control valve is slidably connected to the control seat, and the control valve is fixedly connected to the bottom of the sliding tube. The control seat is electrically connected to the motor, and the motor speed can be increased by sliding the control valve upward. When the control valve is at the bottom of the control seat, the motor is at its normal speed. When the piston pushes the sliding tube upward, the sliding tube will drive the control valve to slide upward along the control seat, thereby increasing the motor speed.
[0011] Preferably, the scraping assembly includes a blocking ring, a bearing ring, a sliding ring, a track, a second elastic element, an extension plate, an arc-shaped groove, an arc-shaped slider, a third elastic element, a stirring plate, a first fixing block, a second fixing block, a fourth elastic element, a toggle element, and a counterweight. The blocking ring is fixedly connected near the lower part of the shaft, the bearing ring is fixedly connected to the lower end of the shaft, the sliding ring is slidably connected between the blocking ring and the bearing ring, the track is arranged on the sliding path of the sliding ring and fixedly connected to the outer wall of the shaft, two sets of tracks are provided and symmetrically arranged along the axis of the shaft, and the second elastic element is located on the sliding... Between the ring and the bearing ring, the top end of the second elastic element is fixedly connected to the sliding ring, and the bottom end is fixedly connected to the bearing ring. Two sets of extension plates are provided and fixedly connected to the sliding ring. The two sets of extension plates are symmetrically arranged along the center point of the sliding ring and on a straight line. The arc-shaped groove is fixedly connected to the end of the extension plate. The arc-shaped slider is slidably connected to the arc-shaped groove. The third elastic element is located between the end of the arc-shaped slider and the end baffle of the arc-shaped groove. One end of the third elastic element is fixedly connected to the end of the arc-shaped slider, and the other end is fixedly connected to the end baffle of the arc-shaped groove. The stirring plate is located below the arc-shaped slider. The stirring plate is inclined, and its bottom arc matches and fits the bottom arc of the mixing vessel. Fixing block one and fixing block two are fixedly connected to the top surface of the stirring plate. Fixing block one is rotatably connected to the lower right end of the arc-shaped slider via a rotating shaft. Fixing block two is connected to the lower left end of the arc-shaped slider via an elastic element four. The actuating element is located between fixing block two and the arc-shaped slide groove. The counterweight is located between the sliding ring and the bearing ring. The sliding ring has a slot for sliding engagement with the track, allowing it to rotate with the shaft. When the shaft rotates, it drives the sliding ring... The ring and extension plate rotate simultaneously, which in turn drives the stirring plate to rotate. Under the thrust of the elastic element four, the stirring plate will remain in contact with the bottom of the mixing vessel. During the clockwise rotation of the stirring plate driven by the shaft, the elastic element three will always maintain a thrust on the arc-shaped slider. When the temperature is too high and a blockage occurs at a certain point in the running path of the stirring plate, the passing stirring plate will be resisted by the blockage and the resistance will be transmitted to the arc-shaped slider. Then the arc-shaped slider will overcome the thrust of the elastic element four and retract into the arc-shaped groove. This can play a buffering role when the stirring plate encounters the blockage, preventing damage caused by direct rigid contact.
[0012] Preferably, the actuating component includes a through-hole, an extension rod, and a steel wire rope; the through-hole is located at the left end of the arc-shaped slider, the extension rod is fixedly connected to the left end of the arc-shaped groove, and the steel wire rope passes through the through-hole with one end fixedly connected to the fixed block and the other end fixedly connected to the end of the extension rod; when the stirring plate is subjected to the resistance of the agglomeration and transmits the resistance to the arc-shaped slider, causing it to retract into the arc-shaped groove, the left side of the stirring plate will move closer to the arc-shaped slider, thus playing a actuating role on the agglomeration at the bottom of the stirring vessel. Even if the agglomeration is hard, the swinging stirring plate can pass over the agglomeration, and the agglomeration will be scraped off the next time it passes.
[0013] Preferably, the counterweight is provided in two sets and symmetrically arranged along the central axis of the bearing ring; the counterweight includes a first hinge rod, a second hinge rod, and a counterweight block; the first hinge rod is hinged to the connection between the sliding ring and the extension plate, the second hinge rod is hinged to the bearing ring, and the counterweight block is hinged to both the first and second hinge rods; as the stirring plate rotates clockwise following the shaft, under the action of centrifugal force, the counterweight block will gradually reduce the angle between the first and second hinge rods as the shaft speed gradually increases. Consequently, as the rotation speed increases, the counterweight block will pull the extension plate and the sliding ring through the first and second hinge rods to overcome the elastic force of the second elastic element and gradually move towards the bearing ring. As the extension plate and the sliding ring move downward, the pressure of the stirring plate on the bottom of the stirring vessel increases.
[0014] Preferably, the conveying assembly includes a reciprocating screw, a mounting frame, a reciprocating slider, a connecting frame, a liquid storage chamber, a vertical groove, a first check valve, a partition, a second check valve, and a push column; the reciprocating screw is sleeved on the outside of the shaft and fixedly connected to the shaft, the reciprocating screw is rotatably connected to the mounting frame, and the mounting frame is fixedly connected to the inner wall of the mixing vessel, the reciprocating slider is slidably connected to the mounting frame, the connecting frame is fixedly connected to the reciprocating slider, the liquid storage chamber is opened inside the shaft, the vertical grooves are symmetrically opened on both sides of the top of the shaft, the connecting frame is slidably connected to the vertical grooves, the top of the push column is fixedly connected to the connecting frame, and the first check valve is fixedly connected at the middle position of the shaft. The partition is fixedly connected inside the shaft and located below the first check valve. The second check valve is fixedly connected at the center of the partition. During the rotation of the reciprocating screw driven by the shaft, the reciprocating screw drives the reciprocating slider to move up and down on the mounting frame. This, in turn, drives the push column to move up and down in the storage chamber through the connecting frame. When the push column slides upward, the first check valve opens and the second check valve closes, allowing the dairy liquid to be drawn into the storage chamber. When the push column slides downward, the first check valve closes and the second check valve opens, allowing the dairy liquid in the storage chamber to be injected downward toward the shaft. The injected liquid will impact and enter the recessed area of the outlet.
[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] 1. By setting a temperature control component, when the temperature of the heating medium is too high and the temperature inside the mixing vessel exceeds the set temperature, the high-pressure gas inside the mixing vessel will push the top rod and sliding tube upward through the piston. During the upward movement, the water inlet hole on the sliding tube will gradually be exposed in the sliding cavity. Therefore, the coolant in the water inlet pipe connected to the external coolant storage tank will enter the sliding tube through the water inlet hole, and then enter the threaded pipe along the hose to cool the heating medium in the heating cavity. This prevents the heating medium from continuing to heat the dairy products inside the mixing vessel, effectively preventing the gelatinization reaction of the dairy products caused by excessively high temperature inside the mixing vessel. Furthermore, as the temperature inside the mixing vessel increases, the coolant flow rate increases, and the cooling effect becomes stronger. At the same time, as the high-pressure gas pushes the top rod and sliding tube upward through the piston, the sliding tube will drive the control valve to slide upward along the control seat, thereby increasing the motor speed. This allows for automatic increase in the stirring rate when the temperature is high, preventing the occurrence of gelatinization reaction.
[0017] 2. By setting up a scraping component, the shaft rotates clockwise, which also drives the stirring plate to rotate. Under the thrust of the elastic element four, the stirring plate will remain in contact with the bottom of the mixing vessel, scraping to prevent the bottom surface of the mixing vessel from gelatinizing and clumping due to high temperature. When the temperature is too high and clumping occurs at a certain point in the running path of the stirring plate, the stirring plate passing through the clumping point will be resisted by the clumping and the resistance will be transmitted to the arc-shaped slider. Then, the arc-shaped slider will overcome the thrust of the elastic element four and retract into the arc-shaped groove. The arc-shaped slider will slide to the right relative to the extension rod, and then pull the stirring plate along the rotation of the fixed block one position through the steel wire rope. As the shaft swings upwards, the left side of the stirring plate moves closer to the arc-shaped slider, thus acting as a lever to remove clumps at the bottom of the mixing vessel, protecting the stirring plate and improving the scraping effect. Simultaneously, as the shaft speed gradually increases, the counterweight will pull the extension plate and sliding ring through hinge rod one and hinge rod two, overcoming the elastic force of elastic element two and gradually moving towards the bearing ring. As the extension plate and sliding ring move downwards, the pressure of the stirring plate on the bottom of the mixing vessel increases, resulting in a stronger scraping effect, further preventing clump formation and improving the stirring effect of the stirring plate.
[0018] 3. By setting up a conveying component, the rotating shaft will also drive the liquid pusher column to move up and down in the storage chamber. When the liquid pusher column slides upward, one-way valve one opens and one-way valve two closes, thus allowing the dairy liquid to be drawn into the storage chamber. When the liquid pusher column slides downward, one-way valve one closes and one-way valve two opens, thus allowing the dairy liquid in the storage chamber to be injected downward towards the shaft. The injected liquid will impact the recessed area of the outlet, flushing out the sediment in the recessed area and then being stirred and dispersed to prevent the sediment from settling in the recessed area.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] Please see Figures 1 to 8 This invention provides a dairy product production and processing equipment with temperature control function, the technical solution of which is as follows:
[0030] Reference Figure 1 and Figure 2A dairy product processing equipment with temperature control function includes a mixing tank 1, a feed inlet 11, a discharge outlet 12, a motor 13, a shaft 14, stirring blades 15, a heating chamber 2, a heat medium inlet 21, a heat medium outlet 22, a temperature control component 3, a scraping component 4, and a conveying component 5. The feed inlet 11 is located at the top of the mixing tank 1, the discharge outlet 12 is located at the bottom of the mixing tank 1, the motor 13 is located at the top of the mixing tank 1, the shaft 14 is located on the central axis of the mixing tank 1 and is fixedly connected to the output shaft of the motor 13, and two sets of stirring blades 15 are provided and fixedly connected to the shaft 14. Two sets of stirring blades 15 are respectively located near the middle and upper part of the shaft 14. The heating chamber 2 is located outside the mixing vessel 1 and surrounds it. The heat medium inlet 21 and the heat medium outlet 22 are both located at the bottom of the heating chamber 2. The temperature control component 3 is located on the outer wall of the mixing chamber. The scraping component 4 is located at the bottom end of the shaft 14 and contacts the inner bottom wall of the mixing vessel 1. The conveying component 5 is located at the top of the shaft 14 and moves up and down reciprocating with the rotation of the shaft 14. In use, starting the motor 13 will drive the shaft 14 and the stirring blades 15 to rotate inside the mixing vessel 1, thereby stirring the dairy products inside the mixing vessel 1. The heating medium enters the heating chamber 2 through the heating medium inlet 21 and exits through the heating medium outlet 22. The heating medium circulates continuously to heat the dairy products in the stirring vessel 1. The dairy raw materials are gradually made into condensed milk during heating and stirring. When the temperature of the heating medium is too high and the temperature inside the stirring vessel 1 exceeds the set temperature, the expansion pressure inside the stirring vessel 1 will gradually push the temperature control component 3 to open the liquid cooling circulation for cooling. At the same time, as the temperature inside the stirring vessel 1 rises, the speed of the motor 13 can be automatically increased to accelerate the stirring rate of the dairy products and prevent gelatinization. During the stirring process, the scraping component 4 can adhere and stir the bottom of the stirring vessel 1. To prevent the bottom temperature of the mixing vessel 1 from becoming too high and causing surface gelatinization and clumping, and when the temperature rises rapidly and encounters clumping, the scraping component 4 pushes the clumping upward as it passes over it. Furthermore, the scraping component 4 gradually increases its resistance to the bottom of the mixing vessel 1 as the rotation speed of the shaft 14 increases. While the shaft 14 is rotating, the conveying component 5 can draw the dairy liquid above the mixing vessel 1 to the bottom of the mixing vessel 1, which can further ensure the uniformity of mixing. At the same time, the dairy liquid drawn to the bottom of the mixing vessel 1 can impact the recessed area of the discharge port 12, dispersing the sediment there and preventing accumulation.
[0031] Reference Figure 2 The discharge port 12 is located at the bottom center axis of the mixing vessel 1, and the shaft 14 and the liquid outlet are on the same axis. When the conveying assembly 5 is working, the liquid discharged from the shaft 14 can just impact the depression formed by the discharge port 12, preventing the sediment in the dairy liquid from depositing here.
[0032] Reference Figures 2 to 4The temperature control component 3 includes a gas valve 31, a pressure pipe 32, a piston 33, a fixing ring 34, an elastic element 35, and a cooling component 36. The gas valve 31 passes through the heating chamber 2 and is connected to the stirring vessel 1, and the gas valve 31 is located at the top of the stirring vessel 1. The pressure pipe 32 is fixedly connected to the outer wall of the heating chamber 2, and the pressure pipe 32 and the gas valve 31 are connected by a metal pipe. The piston 33 is slidably connected to the pressure pipe 32. The fixing ring 34 is fixedly connected to the top of the pressure pipe 32. The elastic element is located between the fixing ring 34 and the piston 33. The cooling component 36 is located above the pressure pipe 32. When the temperature in the stirring vessel 1 is too high, the gas pressure will also increase accordingly. Then, the high-pressure gas will be discharged from the gas valve 31 and enter the pressure pipe 32 through the metal pipe, pushing the piston 33 to move upward against the thrust of the elastic element 35. When the temperature returns to normal, the elastic element 35 will push the piston 33 downward.
[0033] Reference Figures 2 to 4The cooling component 36 includes a water inlet pipe 361, a sliding cavity 362, a sliding tube 363, a water inlet hole 364, a threaded tube 365, a flexible hose 366, and a push rod 367. The water inlet pipe 361 is fixedly connected to the outer wall of the heating cavity 2. The sliding cavity 362 is fixedly connected to the bottom of the water inlet pipe 361 and communicates with the water inlet pipe 361. The top of the sliding tube 363 extends into the water inlet pipe 361 and is slidably connected to the sliding cavity 362. Multiple sets of water inlet holes 364 are provided and are vertically opened on the sliding tube 363. The threaded tube 365 is spirally wound around the outside of the stirring vessel 1 and positioned... Inside the heating chamber 2, the threaded tube 365 and the sliding tube 363 are connected by a flexible hose 366. A push rod 367 is fixedly connected to the top of the piston 33, and the top of the push rod 367 is fixedly connected to the bottom of the sliding tube 363. The top of the water inlet pipe 361 is connected to an external coolant storage tank. The coolant circulates through the threaded tube 365 from beginning to end and then returns to the coolant storage tank. When the temperature inside the stirring vessel 1 is too high, the high-pressure gas will push the push rod 367 and the sliding tube 363 upwards through the piston 33. As the temperature continues to rise, the gas pressure will also... As the piston 33 continues to increase in size and gradually rises, it will gradually push the sliding tube 363 upward within the inlet pipe 361 via the push rod 367. During this upward movement, the inlet hole 364 on the sliding tube 363 will gradually expose the sliding cavity 362. Therefore, the coolant in the inlet pipe 361, which is connected to the external coolant storage tank, will enter the sliding tube 363 through the inlet hole 364, and finally enter the threaded pipe 365 along the hose 366 to complete the circulation before being discharged to the external coolant storage tank. This process cools the heat medium in the heating chamber 2 and blocks the flow of heat. The material continues to heat the dairy products in the mixing vessel 1. As the temperature and pressure inside the mixing vessel 1 increase, the piston 33 will push the sliding tube 363 to rise a greater distance, and more water inlet holes 364 will be exposed in the water inlet pipe 361. Therefore, the flow rate of coolant entering the threaded pipe 365 will be greater, and the cooling effect will be stronger. When the temperature returns to normal, the elastic element 35 will pull the top rod 367 down, which will in turn drive the sliding tube 363 down, so that all the water inlet holes 364 are retracted into the sliding cavity 362, thereby blocking the circulation of coolant.
[0034] Reference Figure 3 and Figure 4 A control seat 3621 for controlling the speed of motor 13 is fixedly connected to the outside of the sliding cavity 362. A control valve 3622 is slidably connected to the control seat 3621. The control valve 3622 is fixedly connected to the bottom of the sliding tube 363. The control seat 3621 is electrically connected to motor 13. The speed of motor 13 can be increased by sliding the control valve 3622 upward. When the control valve 3622 is at the bottom of the control seat 3621, the motor 13 is at normal speed. When the piston 33 pushes the sliding tube 363 upward, the sliding tube 363 will drive the control valve 3622 to slide upward along the control seat 3621, thereby increasing the speed of motor 13.

The elastic element 45 is located between the sliding ring 43 and the bearing ring 42. The elastic element 45 is fixedly connected at its top end to the sliding ring 43 and at its bottom end to the bearing ring 42.

One end of the elastic element 49 is fixedly connected to the end of the arc-shaped slider 48, and the other end is fixedly connected to the end baffle of the arc-shaped groove 47. A stirring plate 410 is located below the arc-shaped slider 48. The stirring plate 410 is inclined, and its bottom curvature matches and fits the bottom curvature of the mixing vessel 1. Both fixed block 411 and fixed block 412 are fixedly connected to the top surface of the stirring plate 410. Fixed block 411 is rotatably connected to the lower right end of the arc-shaped slider 48 via a rotating shaft. Fixed block 412 is connected to the lower left end of the arc-shaped slider 48 via an elastic element 413. A toggle element 414 is disposed between fixed block 412 and the arc-shaped slide groove 47. A counterweight 415 is disposed between the sliding ring 43 and the bearing ring 42. The sliding ring 43 has a slot for sliding engagement with the track 44, so the sliding ring 43 can rotate with the shaft 14. Under the thrust of the elastic element 45, the sliding ring 43 will remain in contact with the fixed ring 34. When the shaft 14 rotates, it will drive the sliding ring 43 and the extension plate 46 to rotate simultaneously, thereby driving the stirring plate 410. During rotation, under the thrust of the elastic element 413, the stirring plate 410 will remain in contact with the bottom of the mixing vessel 1. This allows it to scrape the bottom surface of the mixing vessel 1 during rotation, preventing it from becoming pasty and clumped. As the shaft 14 drives the stirring plate 410 to rotate clockwise, the elastic element 49 will always maintain a thrust on the arc-shaped slider 48. When the temperature is too high and clumping occurs at a certain point in the running path of the stirring plate 410, the passing stirring plate 410 will be resisted by the clumping and the resistance will be transmitted to the arc-shaped slider 48. The arc-shaped slider 48 will then overcome the thrust of the elastic element 413 and retract into the arc-shaped groove 47. This provides a buffer when the stirring plate 410 encounters clumping, preventing damage caused by direct rigid contact.
[0036] Reference Figure 5 and Figure 6 The actuating element 414 includes a through-hole 4141, an extension rod 4142, and a steel wire rope 4143. The through-hole 4141 is located at the left end of the arc-shaped slider 48. The extension rod 4142 is fixedly connected to the left end of the arc-shaped groove 47. The steel wire rope 4143 passes through the through-hole 4141, with one end fixedly connected to the fixed block 412 and the other end fixedly connected to the end of the extension rod 4142. When the stirring plate 410 is subjected to agglomeration resistance and transmits the resistance to the arc-shaped slider 48, causing it to retract into the arc-shaped groove 47, the arc-shaped slider... 48 slides the relative extension rod 4142 to the right, thereby pulling the stirring plate 410 upward along the rotation axis at the fixed block 411 via the wire rope 4143. The left side of the stirring plate 410 will move closer to the arc-shaped slider 48, thus having a dispersing effect on the clumps at the bottom of the mixing vessel 1. Even if the clumps are hard, the swinging stirring plate 410 can pass over the clumps and scrape them off the next time it passes over them. Therefore, it plays a further protective role for the stirring plate 410 and improves the scraping effect on the clumps.
[0037] Reference Figures 5 to 7 The counterweight 415 has two sets symmetrically arranged along the central axis of the bearing ring 42; the counterweight 415 includes a first hinge rod 4151, a second hinge rod 4152, and a counterweight block 4153; the first hinge rod 4151 is hinged to the connection between the sliding ring 43 and the extension plate 46, the second hinge rod 4152 is hinged to the bearing ring 42, and the counterweight block 4153 is hinged to both the first hinge rod 4151 and the second hinge rod 4152; as the stirring plate 410 rotates clockwise following the shaft 14, the counterweight block 4153, under the action of centrifugal force, will... As the rotational speed of shaft 14 gradually increases, the angle between hinge rod 1 4151 and hinge rod 2 4152 gradually decreases. As the rotational speed increases, counterweight 4153 will pull extension plate 46 and sliding ring 43 through hinge rod 1 4151 and hinge rod 2 4152 to overcome the elastic force of elastic element 2 45 and gradually move downward toward bearing ring 42. As extension plate 46 and sliding ring 43 move downward, the pressure of stirring plate 410 on the bottom of stirring vessel 1 becomes greater, and the scraping effect becomes stronger, which can further prevent the formation of agglomerates.
[0038] Reference Figure 2 and Figure 8The conveying assembly 5 includes a reciprocating screw 51, a mounting frame 52, a reciprocating slider 53, a connecting frame 54, a liquid storage chamber 55, a vertical groove 56, a first check valve 57, a partition 58, a second check valve 59, and a pusher column 510. The reciprocating screw 51 is sleeved on the outside of the shaft 14 and fixedly connected to the shaft 14. The reciprocating screw 51 is rotatably connected to the mounting frame 52, and the mounting frame 52 is fixedly connected to the inner wall of the mixing vessel 1. The reciprocating slider 53 is slidably connected to the mounting frame 52. The connecting frame 54 is fixedly connected to the reciprocating slider 53. The liquid storage chamber 55 is opened inside the shaft 14. The vertical groove 56 is symmetrically opened on both sides of the top of the shaft 14. The connecting frame 54 is slidably connected to the vertical groove 56. The top of the pusher column 510 is fixedly connected to the connecting frame 54. The first check valve 57 is fixedly connected to the middle of the shaft 14. The partition 58 is fixedly connected inside the shaft 14 and positioned... Below the first check valve 57, the second check valve 59 is fixedly connected to the center of the partition 58. During the rotation of the reciprocating screw 51 driven by the shaft 14, the reciprocating screw 51 drives the reciprocating slider 53 to move up and down on the mounting frame 52, and then drives the push column 510 to move up and down in the storage chamber 55 through the connecting frame 54. When the push column 510 slides upward, the first check valve 57 opens and the second check valve 59 closes, so that the dairy liquid can be drawn into the storage chamber 55. When the push column 510 slides downward, the first check valve 57 closes and the second check valve 59 opens, so that the dairy liquid in the storage chamber 55 can be injected downward towards the shaft 14. The injected liquid will impact the recess of the outlet, flush out the sediment in the recess and then be stirred and dispersed to prevent the sediment from settling in the recess.
[0039] Working principle: During operation, the motor 13 will drive the shaft 14 and the stirring blade 15 to rotate clockwise in the stirring vessel 1, thereby stirring the dairy liquid in the stirring vessel 1. At the same time, the heating medium will enter the heating chamber 2 from the heating medium inlet 21 and then be discharged from the heating medium outlet 22. The heating medium continuously heats and circulates, thereby heating the dairy products in the stirring vessel 1. The dairy raw materials can be gradually made into condensed milk during the heating and stirring process.
[0040] When the temperature of the heat medium is too high, causing the temperature inside the stirred tank 1 to exceed the set temperature, the gas pressure inside the stirred tank 1 will also increase. The high-pressure gas will be discharged from the gas valve 31 and then enter the gas pressure pipe 32 through the metal pipe, pushing the piston 33 to move upward against the thrust of the elastic element 35. When the temperature inside the stirred tank 1 is too high, the high-pressure gas will push the push rod 367 and the sliding tube 363 upward through the piston 33. As the temperature continues to rise, the gas pressure will continue to increase. The gradually rising piston 33 will gradually push the sliding tube 363 upward through the push rod 367 in the water inlet pipe 361. During the upward movement, the water inlet hole 364 on the sliding tube 363 will gradually be exposed in the sliding cavity 362. Therefore, the coolant in the water inlet pipe 361, which is connected to the external coolant storage tank, will enter the sliding tube 363 through the water inlet hole 364, and finally enter the threaded pipe 365 through the hose 366 to complete the circulation before being discharged to the external coolant storage tank, thus completing the process. The heating medium in the heating chamber 2 is cooled to prevent it from continuing to heat the dairy products in the stirring vessel 1. As the temperature and pressure inside the stirring vessel 1 increase, the piston 33 pushes the sliding tube 363 upward a greater distance, exposing more water inlet holes 364 in the water inlet pipe 361. This results in a larger flow rate of coolant entering the threaded pipe 365 and a stronger cooling effect. When the temperature inside the stirring vessel 1 returns to normal, the elastic element 35 pulls the top rod 367 downward, which in turn drives the sliding tube 363 downward, causing all the water inlet holes 364 to be drawn into the sliding chamber 362, thus blocking the circulation of coolant. As the high-pressure gas pushes the top rod 367 and the sliding tube 363 upward through the piston 33, the sliding tube 363 drives the control valve 3622 to slide upward along the control seat 3621, thereby increasing the speed of the motor 13. This allows for automatic increase in stirring speed at higher temperatures, preventing gelatinization.
[0041] As shaft 14 rotates clockwise, it also drives sliding ring 43 and extension plate 46 to rotate simultaneously, which in turn drives stirring plate 410 to rotate. Under the thrust of elastic element 413, stirring plate 410 will remain in contact with the bottom of stirring vessel 1, thus scraping the bottom surface of stirring vessel 1 during rotation to prevent gelatinization and clumping. When encountering excessively high temperatures and clumping occurs at a certain point in the running path of stirring plate 410, stirring plate 410 passing through the clumping point will be subject to the resistance of the clumping and will transfer the resistance... The force is transmitted to the arc-shaped slider 48, which then retracts into the arc-shaped groove 47, overcoming the thrust of the elastic element 413. This buffers the stirring plate 410 when it encounters obstructions from clumps, preventing damage from direct rigid contact. During the retraction of the arc-shaped slider 48 into the arc-shaped groove 47, it slides to the right relative to the extension rod 4142, thereby pulling the stirring plate 410 upwards along the rotation axis at the fixed block 411 via the steel wire rope 4143, thus stirring... The left side of the mixing plate 410 will move closer to the arc-shaped slider 48, thus providing a dispersing effect on the clumps at the bottom of the mixing vessel 1. Even if the clumps are hard, the swinging mixing plate 410 can pass over them, and scrape them off on the next pass. This further protects the mixing plate 410 and improves the scraping effect. At the same time, as the mixing plate 410 rotates clockwise with the shaft 14, the counterweight 4153, under the action of centrifugal force, will gradually move with the rotation speed of the shaft 14. As the rotational speed increases, the angle between the first hinge rod 4151 and the second hinge rod 4152 gradually decreases. Consequently, as the rotational speed increases, the counterweight 4153 will pull the extension plate 46 and the sliding ring 43 through the first hinge rod 4151 and the second hinge rod 4152 to overcome the elastic force of the second elastic element 45 and gradually move downward toward the bearing ring 42. As the extension plate 46 and the sliding ring 43 move downward, the pressure of the stirring plate 410 on the bottom of the stirring vessel 1 becomes greater, and the scraping effect becomes stronger, which can further prevent the formation of clumps.
[0042] During the rotation of shaft 14, the reciprocating screw 51 will also be driven to rotate. The reciprocating screw 51 will drive the reciprocating slider 53 to move up and down on the mounting frame 52. In turn, the connecting frame 54 will drive the push column 510 to move up and down in the storage chamber 55. When the push column 510 slides upward, the one-way valve 1 57 opens and the one-way valve 2 59 closes, so that the dairy liquid can be drawn into the storage chamber 55. When the push column 510 slides downward, the one-way valve 1 57 closes and the one-way valve 2 59 opens, so that the dairy liquid in the storage chamber 55 can be injected downward towards shaft 14. The injected liquid will impact the recess of the outlet, flush out the sediment in the recess, and then be stirred and dispersed to prevent the sediment from settling in the recess.
