Description

Technical Field

[0001] The invention relates to the technical field of cheese production sterilization equipment, in particular to cheese production sterilization equipment with an overheating self-isolation function. Background Art

[0002] Cheese is a solid dairy product made from milk coagulated and matured by the action of a starter culture and rennet. Cheese is highly nutritious, rich in protein, calcium, phosphorus, vitamins, and other nutrients. Cheese production is a complex process involving multiple steps, each of which significantly impacts the quality of the final product. Among these, sterilization is crucial, primarily to eliminate harmful bacteria in the milk and ensure the quality and safety of the cheese. Currently, pasteurization is the primary method for sterilizing milk.

[0003] As cheese products become increasingly popular, a large number of pasteurization-based sterilization equipment have appeared on the market. While these devices can achieve certain sterilization goals, they also have many problems. During production, equipment failure or operator error can sometimes cause the sterilization temperature to be too high. At this time, the beneficial bacteria in the milk will lose their activity due to the high temperature, resulting in a loss of nutritional content and significant losses for the manufacturer. Even if the equipment is shut down using the emergency button, it cannot isolate the milk from the heat source in time, affecting the next step of production. For large-volume production equipment, the large internal volume is prone to uneven heating, resulting in localized excessive temperatures and destroying the beneficial bacteria in some parts of the milk. As the sterilization equipment runs for a long time, many milk stains and other substances will remain on the barrel wall, which are difficult to remove. Because the principle of pasteurization is used, the temperature control efficiency of the cheese raw materials is low, affecting production efficiency. Summary of the Invention

[0004] The object of the present invention is to provide a cheese production sterilization device with an overheating self-isolating function to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A sterilization equipment for cheese production with overheating self-isolation function includes a base, a fixed water tank is installed on the base, a controller is installed on the fixed water tank, a support frame is installed on the base, a temperature control barrel is installed on the support frame, a raw material barrel is installed in the temperature control barrel, a stirring device is installed in the raw material barrel, a variable speed drive device is connected to the bottom of the stirring device, the variable speed drive device is used to drive the stirring device and control the speed of the stirring device, the temperature control barrel is used to control the temperature of the cheese raw materials and perform overheating isolation, and the stirring device is used to heat the cheese raw materials evenly and clean the raw material barrel.

[0006] The controller houses a control system that controls the entire sterilization system. The fixed water tank houses a cold water tank, a hot water tank, and a water pump. The cold water tank is kept at the low temperature required for milk preservation, while the hot water tank is kept at the high temperature required for pasteurization. The cold water tank is connected to the spiral hollow tube and the tank body via pipes, while the hot water tank is connected to the spiral hollow tube and the tank body via pipes.

[0007] The temperature control barrel includes an outer barrel wall, a barrel bottom is installed at the bottom end of the outer barrel wall, the barrel bottom is installed on the base through a support frame, a limit column is slidably installed on the outer barrel wall, a mobile water tank is slidably installed between the limit columns, a sliding ring is installed inside the outer barrel wall, the mobile water tank is slidably connected to the sliding ring, a raw material barrel is movably connected to the sliding ring, a rotating table is rotatably installed on the barrel bottom, the rotating table is connected to the raw material barrel by a threaded connection, the bottom end of the stirring device is connected to the barrel bottom, a first motor is installed on the barrel bottom, a gear is installed on the output shaft of the first motor, the gear is meshed with the rotating table for transmission, the speed change drive device is connected to the barrel bottom, and a limit top cover is installed on the top of the outer barrel wall.

[0008] A drain pipe is installed on the outer barrel wall. Under normal conditions, the fixture snaps into place with the raw material barrel. The barrel is equipped with a top cover for adding materials and observing the internal conditions. A temperature sensor is installed between the inner wall of the barrel and the central axis to transmit temperature changes of the milk inside the barrel to the control system. Drain holes are provided on the side of the barrel, corresponding to the drain pipe and each equipped with an electric valve. A sealing connector is installed at the connection between the drain hole and the drain pipe. When the barrel needs to be drained, the control system rotates the drain hole to the drain pipe, aligning the two, and then opens the electric valve to start draining. Under normal conditions, the bottom of the barrel contacts the upper surface of the sliding ring, and the box body contacts the outer surface of the barrel to transfer heat.

[0009] The milk raw materials for cheese production are poured into the raw material barrel. At this time, the milk that has just been cooled is in a low temperature state. The control system turns on the fixed water tank, and the fixed water tank sends hot water into the spiral hollow tube and the box body through the water pump. Part of the hot water flows in a spiral along the wall of the spiral hollow tube to heat the milk in the raw material barrel, and the other part of the hot water flows along the pipes inside the box body, so that the entire box surface generates high temperature to heat the milk in the raw material barrel.

[0010] The stirring device includes a spiral hollow tube, a bearing connecting ring and a telescopic spraying device. One end of the telescopic spraying device is connected to the interior of the spiral hollow tube, and a scraper is installed at the other end of the telescopic spraying device. A stirring blade is installed on the telescopic spraying device. The spiral hollow tube is rotatably connected to the telescopic tube through the bearing connecting ring. The telescopic tube is installed on the bottom of the barrel. A variable speed drive device is installed on the spiral hollow tube. The bottom and top ends of the raw material barrel are respectively provided with a first sealed bearing and a second sealed bearing. The spiral hollow tube is rotatably connected to the raw material barrel through the first sealed bearing and the second sealed bearing.

[0011] Electric valves are installed at the top and bottom ends of the spiral hollow tube. The first sealing bearing and the second sealing bearing are both bearing structures, and waterproof sealing rings are provided at the connections between the first sealing bearing and the second sealing bearing and the hollow threaded tube and the raw material barrel. The telescopic tube is used to maintain the connection with the spiral hollow tube by its own extension when the spiral hollow tube moves upward with the raw material barrel. The bearing connecting ring is used to prevent the rotation of the upper spiral hollow tube from being affected when the telescopic tube does not rotate.

[0012] The electromagnetic reducing ring drives the spiral hollow tube to rotate rapidly within the raw material barrel. The scrapers and stirring blades on the spiral hollow tube rotate and stir the milk, ensuring even heating. The temperature sensor converts the temperature change of the milk into an electrical signal, which is transmitted to the control system. After receiving the signal, the control system cuts off the power supply to the electromagnetic ring when the milk reaches the sterilization temperature. Based on the previous principle, the diameter of the electromagnetic reducing ring increases, while the diameter of the spring reducing ring decreases, thereby reducing the rotation speed of the spiral hollow tube and slowing the stirring. After the high-temperature sterilization is completed, the control system controls the fixed water tank to switch from hot water to cold water. The cold water flows through the spiral hollow tube and the tank to cool the milk. The previous operation is repeated, causing the spiral hollow tube to rotate rapidly, rapidly cooling the milk. The rapid temperature change further kills harmful bacteria in the milk, and the cooled milk is discharged, achieving the purpose of sterilizing the cheese milk raw material.

[0013] The telescopic spraying device includes a telescopic housing connected to the interior of a spiral hollow tube. A liquid storage tank is mounted on the spiral hollow tube, forming a water inlet chamber between the telescopic housing and the liquid storage tank. A telescopic push rod is slidably mounted within the liquid storage tank and slidably connected to the telescopic housing. A third spring is installed between the telescopic push rod and the telescopic housing. A compression head is slidably mounted on the top of the telescopic push rod. A second spring is installed between the compression head and the telescopic push rod. The compression head is provided with a water spray hole and a scraper. A stirring blade is mounted on the telescopic housing. The telescopic push rod is provided with a drain hole and a water inlet groove. The liquid storage tank is filled with damping fluid to prevent the telescopic push rod from extending too quickly and striking the raw material barrel, causing damage.

[0014] When the milk is sterilized and discharged, the control system injects water into the spiral hollow tube through the fixed water tank. At the same time, the electric valve at the bottom of the spiral hollow tube is closed, so that the water in the spiral hollow tube can only flow in but not out. The water flows from the spiral hollow tube into the telescopic spray device, and the water flows from the water inlet chamber into the water inlet tank, and then enters the interior of the telescopic push rod. As the water in the spiral hollow tube is filled, when water is continued to be injected into the spiral hollow tube, the water pressure in the tube will increase. As the water pressure increases, the telescopic push rod overcomes the thrust of the third spring to compress the third spring, and the telescopic push rod extends toward the raw material barrel. Since one end of the telescopic push rod is affected by the damping fluid, the telescopic push rod slowly and evenly extends under the influence of the damping fluid. When When the telescopic push rod drives the scraper on the compression head to touch the wall of the raw material barrel, the barrel wall will give the compression head a reaction force through the scraper. As the water pressure continues to increase, the telescopic push rod will further extend, thereby increasing the reaction force on the compression head. When the reaction force is greater than the elastic force of the second spring in the compression head, the second spring will be compressed, and one end of the telescopic push rod will continue to slide in the compression head, forming a water spray chamber between the end of the telescopic push rod and the compression head. Water flows into the water spray chamber from the drain hole, and the end of the telescopic push rod moves gradually, causing the volume of the water spray chamber to gradually increase. Until the volume of the water spray chamber expands to cover the water spray hole, high-pressure water is ejected from the water spray hole to spray and clean the wall of the raw material barrel.

[0015] The driving device includes an electromagnetic reducing ring, a belt and a second motor. The electromagnetic reducing ring is installed on the spiral hollow tube, the second motor is installed on the bottom of the barrel, and a spring reducing ring is installed on the output shaft of the second motor. The spring reducing ring is rotatably connected to the electromagnetic reducing ring through a belt.

[0016] The spring reducing ring includes a second roller, a second telescopic rod and a second rolling shaft. The second rolling shaft is installed on the output shaft of the second motor. A fixed ring is installed at the bottom end of the second rolling shaft. A movable ring is slidably installed at the top end of the second rolling shaft. The second roller is rotatably connected to the fixed ring and the movable ring respectively through the second telescopic rod. A fourth spring is installed between the fixed ring and the movable ring. The second roller is rotatably connected to the electromagnetic reducing ring through a belt.

[0017] A bulge is provided on the second rolling shaft, and grooves are provided on the movable ring and the fixed ring. The grooves are engaged with the bulge, and the fourth spring is a tension spring.

[0018] The electromagnetic variable diameter ring contracts, causing the belt to loosen. The movable ring approaches the fixed ring under the tension of the fourth spring, causing the second telescopic rod to drive the second roller to expand outward, so that the diameter of the spring variable diameter ring increases to adapt to the loosened belt. The second motor output shaft drives the spring variable diameter ring to rotate, and the spring variable diameter ring drives the electromagnetic variable diameter ring to rotate through the belt. Since the spring variable diameter ring has a large diameter and the electromagnetic variable diameter ring has a small diameter, the electromagnetic variable diameter ring rotates more circles when the spring variable diameter ring rotates one circle, thereby making the electromagnetic variable diameter ring rotate faster.

[0019] The electromagnetic variable diameter ring includes a first roller, a first telescopic rod and a first rolling shaft. The first rolling shaft is installed at the bottom end of the spiral hollow tube. A fixed ring is installed at the bottom end of the first rolling shaft. An electromagnetic ring is slidably installed at the top end of the first rolling shaft. The first roller is rotatably connected to the electromagnetic ring and the permanent magnet ring respectively through the first telescopic rod, and the first roller and the second roller are rotatably connected through a belt.

[0020] A protrusion is provided on the first rolling shaft, and grooves are provided on the electromagnetic ring and the permanent magnet ring. The grooves are engaged with the protrusions. Under normal conditions, the electromagnetic ring is not energized, and the electromagnetic ring and the permanent magnet ring are adsorbed and fitted together. The distance between the electromagnetic ring and the permanent magnet ring is minimum, and the first telescopic rod drives the first roller to expand outward. The electromagnetic variable diameter ring is in the maximum diameter state. When the electromagnetic variable diameter ring is in the maximum diameter state, it drives the belt to expand and tighten the belt. The tightening of the belt generates a gripping force that drives the second roller to tighten. The tightening of the second roller drives the movable ring to overcome the pressure generated by the fourth spring and slide away from the fixed ring, so that the spring variable diameter ring is in the minimum diameter state.

[0021] The control system turns on the second motor. At this time, since heating has just begun, the temperature of the milk near the wall of the raw material barrel and the spiral hollow tube is higher, and the temperature of the milk between the wall of the raw material barrel and the spiral hollow tube is still at a low temperature. The control system supplies power to the electromagnetic ring, and the electromagnetic ring generates the same magnetic field as the permanent magnet ring. According to the principle of like charges repel, the electromagnetic ring slides upward along the first rolling axis, and the distance between the electromagnetic ring and the permanent magnet ring increases. The first telescopic rod connecting the electromagnetic ring and the permanent magnet ring contracts inward, driving the first roller to contract inward, so that the diameter of the electromagnetic variable diameter ring becomes smaller.

[0022] The limiting column includes a column body, a fixing device mounted on the column body, a sliding column mounted on the column body, and a column slot provided on the column body. The column body is slidably connected to the mobile water tank through the sliding column, and the column body is slidably connected to the outer barrel wall. A protrusion is provided on the inner side of the outer barrel arm, which engages with the column slot, allowing the column body to slide along the direction of the protrusion.

[0023] The control system supplies power to the electromagnetic block, which absorbs the telescopic block so that the raw material barrel and the limit column are no longer stuck. The control system turns on the first motor and the second motor, and the second motor drives the spiral hollow tube to rotate, and the spiral hollow tube drives the scraper on it to clean the raw material barrel. The first motor drives the turntable to rotate through the gear, and the turntable drives the raw material barrel to rotate. At this time, the raw material barrel is not affected by the limit column and rotates with the turntable. The control system controls the rotation speed of the spiral hollow tube through the electromagnetic reducing ring, so that the spiral hollow tube and the raw material barrel rotate differentially or rotate forward and backward to cooperate with the scraper to clean the barrel wall of the raw material barrel, and finally discharge the cleaned sewage, thereby realizing multi-stage self-cleaning of the sterilization equipment.

[0024] The mobile water tank includes a box body, with inclined grooves on both sides of the box body, a slider at the bottom of the box body, the slider is an inverted T-shape, a water inlet and a water outlet are symmetrically arranged at the bottom of the box body, the box body is slidably connected to the column, and the box body is slidably connected to the sliding ring.

[0025] The inside of the box is covered with water pipes, which are used to bring in and out cold and hot water. The two ends of the water pipes are connected to the water inlet and outlet respectively. The sliding column slides in the inclined groove. The sliding ring is provided with a slide groove that matches the slider, and the slider slides in the slide groove.

[0026] The fixing device includes a telescopic card block mounted on the column, a first spring installed between the telescopic card block and the column, and an electromagnetic block installed in the column. A slot matching the telescopic card block is provided on the wall of the raw material barrel, so that the telescopic card block can clamp the raw material barrel through the slot.

[0027] When the milk is overheated due to a malfunction in certain parts of the sterilization equipment, to prevent the continued high temperature from destroying the beneficial bacteria in the milk or causing other damage, the control system detects through electrical signals that the milk temperature is above the warning temperature and turns on the first motor. The first motor drives the rotating table to rotate via gears. At this time, the raw material barrel and the limit post are locked together by a fixing device and cannot rotate. As the rotating table rotates, the raw material barrel slides upward via the thread, and the raw material barrel drives the limit post upward with it. The sliding post on the limit post slides upward within the inclined groove of the box. Because the bottom of the box is equipped with an inverted T-shaped slider, the box can only slide back and forth on the sliding ring. Therefore, the upward movement of the sliding post drives the box to slide through the inclined groove, moving the box away from the raw material barrel and contacting the outer barrel wall. The raw material barrel is now isolated from the box on all sides, and the bottom of the raw material barrel is separated from the sliding ring, achieving self-isolation protection for the raw material barrel from overheating. At the same time, the control system controls the fixed water tank to cut off the water supply to the spiral hollow pipe, allowing the hot water in the spiral hollow pipe to be quickly discharged.

[0028] Compared with the existing technology, the beneficial effects achieved by the present invention are: 1. The spiral hollow tube and the box are used to heat or cool the milk from both the inside and the outside at the same time, so that the milk is heated faster, which greatly improves the speed of heating and sterilization. At the same time, it also makes the temperature of the milk change more quickly, so that the harmful bacteria in the milk lose their activity in the faster temperature change.

[0029] 2. Use a movable box to heat the raw material barrel externally. When the control system detects that the milk temperature exceeds the warning temperature, it quickly rotates the turntable to raise the raw material barrel, allowing the mobile water tank to slide away from the raw material barrel and quickly discharge the hot water in the spiral hollow tube, thereby isolating the raw material barrel from overheating from the inside, bottom and all around, and preventing the beneficial bacteria in the cheese raw materials from overheating and being destroyed in all directions.

[0030] 3. The retractable spray device on the stirring device increases water pressure to spray and rinse the raw material barrel. Combined with the rotation of the raw material barrel and the stirring device, this device achieves multi-stage cleaning of the raw material barrel, completely rinsing milk stains and other residues from the barrel walls. This device achieves temperature control, raw material stirring, barrel wall stain removal, and high-pressure water spray cleaning through the stirring device.

[0031] 4. The electromagnetic reducing ring and the spring reducing ring are used to achieve adjustable speed of the stirring device. When heating starts, the milk is heated quickly through rapid stirring to prevent the local temperature of the milk from being too high and destroying the beneficial ingredients of the milk. When the milk reaches the sterilization temperature, the stirring device is made to stir slowly and evenly to keep the milk at the sterilization temperature and sterilize it for a long time. The milk is stirred by multiple groups of scrapers and stirring blades on the stirring device to heat the milk evenly. At the same time, the telescopic spraying device is used to drive the scraper to extend outward to the wall of the raw material barrel so that the scraper can scrape off the milk stains on the wall of the raw material barrel. The telescopic spraying device sprays high-pressure water at multiple angles to spray the barrel wall at multiple angles and wash away the stains. BRIEF DESCRIPTION OF THE DRAWINGS

When the electromagnetic variable ring 81 is in the maximum diameter state, it drives the belt 82 to expand and tighten the belt 82. The tightening of the belt 82 generates a gripping force that drives the second roller 833 to tighten. The tightening of the second roller 833 drives the movable ring 831 to overcome the pressure generated by the fourth spring 836 and slide away from the fixed ring 835, so that the spring variable ring 83 is in the minimum diameter state.

[0053] The driving device includes an electromagnetic reducing ring 81, a belt 82 and a second motor 84. The electromagnetic reducing ring 81 is installed on the spiral hollow tube 71, the second motor 84 is installed on the barrel bottom 18, and a spring reducing ring 83 is installed on the output shaft of the second motor 84.

The movable ring 831 approaches the fixed ring 835 under the tension of the fourth spring 836, causing the second telescopic rod 834 to drive the second roller 833 to expand outward, so that the diameter of the spring variable diameter ring 83 increases to adapt to the loosened belt 82. The output shaft of the second motor 84 drives the spring variable diameter ring 83 to rotate, and the spring variable diameter ring 83 drives the electromagnetic variable diameter ring 81 to rotate through the belt 82. Since the spring variable diameter ring 83 has a large diameter and the electromagnetic variable diameter ring 81 has a small diameter, one rotation of the spring variable diameter ring 83 causes the electromagnetic variable diameter ring 81 to rotate more circles, thereby making the electromagnetic variable diameter ring 81 rotate faster.

[0066] The working principle of the present invention is as follows: the milk raw material for cheese production is poured into the raw material barrel 2. At this time, the milk that has just been cooled is in a low-temperature state. The control system turns on the fixed water tank 3, and the fixed water tank 3 sends hot water into the spiral hollow tube 71 and the box body 171 through the water pump. Part of the hot water flows in a spiral along the wall of the spiral hollow tube 71 to heat the milk in the raw material barrel 2, and the other part of the hot water flows along the pipes distributed inside the box body 171, so that the entire surface of the box body 171 generates high temperature to heat the milk in the raw material barrel 2.

[0067] The control system turns on the second motor 84. At this time, since heating has just begun, the temperature of the milk near the wall of the raw material barrel 2 and the spiral hollow tube 71 is relatively high, and the temperature of the milk between the wall of the raw material barrel 2 and the spiral hollow tube 71 is still at a low temperature. The control system supplies power to the electromagnetic ring 811, and the electromagnetic ring 811 generates the same magnetic field as the permanent magnet ring 815. According to the principle of like charges repel, the electromagnetic ring 811 slides upward along the first rolling axis 812, and the distance between the electromagnetic ring 811 and the permanent magnet ring 815 increases. The first telescopic rod 814 connecting the electromagnetic ring 811 and the permanent magnet ring 815 contracts inward, driving the first roller 813 to contract inward together, so that the diameter of the electromagnetic reducing ring 81 becomes smaller.

[0068] The electromagnetic variable diameter ring 81 contracts, causing the belt 82 to loosen. The movable ring 831 approaches the fixed ring 835 under the tension of the fourth spring 836, causing the second telescopic rod 834 to drive the second roller 833 to expand outward, so that the diameter of the spring variable diameter ring 83 increases to adapt to the loosened belt 82. The output shaft of the second motor 84 drives the spring variable diameter ring 83 to rotate, and the spring variable diameter ring 83 drives the electromagnetic variable diameter ring 81 to rotate through the belt 82. Since the spring variable diameter ring 83 has a large diameter and the electromagnetic variable diameter ring 81 has a small diameter, one rotation of the spring variable diameter ring 83 causes the electromagnetic variable diameter ring 81 to rotate more circles, thereby making the electromagnetic variable diameter ring 81 rotate faster.

[0069] The electromagnetic reducing ring 81 drives the spiral hollow tube 71 to rotate rapidly within the raw material barrel 2. The scraper 72 and stirring blades 73 on the spiral hollow tube 71 rotate and stir the milk, ensuring uniform heating. The temperature sensor converts the temperature change of the milk into an electrical signal and transmits it to the control system. After receiving the signal, the control system cuts off the power to the electromagnetic ring 811 when the milk temperature reaches the sterilization temperature. According to the previous principle, the diameter of the electromagnetic reducing ring 81 increases and the diameter of the spring reducing ring 83 decreases, thereby reducing the rotation speed of the spiral hollow tube 71 and slowing the stirring. After the high-temperature sterilization is completed, the control system controls the fixed water tank 3 to switch from hot water to cold water. The cold water flows through the spiral hollow tube 71 and the tank 171 to cool the milk. The previous operation is repeated, causing the spiral hollow tube 71 to rotate rapidly, rapidly cooling the milk. The rapid temperature change further kills harmful bacteria in the milk, and the cooled milk is discharged, achieving the purpose of sterilizing the cheese milk raw material.

[0070] When the milk is overheated due to a malfunction of some device parts in the sterilization equipment, in order to prevent the continued high temperature from destroying the beneficial bacteria in the milk or causing other damage, the control system judges through an electrical signal that the temperature of the milk is higher than the warning temperature, and turns on the first motor 15. The first motor 15 drives the rotating platform 14 to rotate through the gear. At this time, the raw material barrel 2 and the limiting column 12 are clamped together by the fixing device 121 and cannot rotate. When the rotating platform 14 rotates, the raw material barrel 2 slides upward through the thread, and the raw material barrel 2 drives the limiting column 12 to slide upward together, and the sliding column 122 on the column 124 of the limiting column 12 moves upward. The upper portion slides in the inclined groove 172 of the box body 171. Since an inverted T-shaped slider 173 is installed at the bottom of the box body 171, the box body 171 can only slide back and forth on the sliding ring 13. Therefore, when the sliding column 122 moves upward, it drives the box body 171 to slide through the inclined groove 172, so that the box body 171 is away from the raw material barrel 2 and contacts the outer barrel wall 11. At this time, the raw material barrel 2 is isolated from the box body 171 on all sides, and the bottom of the raw material barrel 2 is separated from the sliding ring 13, realizing the overheating self-isolation protection of the raw material barrel 2. At the same time, the control system controls the fixed water tank 3 to cut off the water supply to the spiral hollow tube 71, and quickly discharges the hot water in the spiral hollow tube 71.

[0071] When the milk is sterilized and discharged, the control system injects water into the spiral hollow tube 71 through the fixed water tank 3. At the same time, the electric valve at the bottom of the spiral hollow tube 71 is closed, so that the water in the spiral hollow tube 71 can only flow in but not out. The water flows from the spiral hollow tube 71 into the telescopic spray device 74, and the water flows from the water inlet chamber 7410 into the water inlet tank 747, thereby entering the telescopic push rod 745. As the water in the spiral hollow tube 71 is filled, when water is continued to be injected into the spiral hollow tube 71, the water pressure in the tube will increase. As the water pressure increases, the telescopic push rod 745 overcomes the thrust of the third spring 748 to compress the third spring 748, and the telescopic push rod 745 extends toward the raw material barrel 2. Since one end of the telescopic push rod 745 is affected by the damping fluid, the telescopic push rod 745 extends slowly and evenly. When the telescopic push rod 745 drives When the scraper 72 on the compression head 742 touches the barrel wall of the raw material barrel 2, the barrel wall will give the compression head 742 a reaction force through the scraper 72. As the water pressure continues to increase, the telescopic push rod 745 further extends, thereby increasing the reaction force on the compression head 742. When the reaction force is greater than the elastic force of the second spring 743 in the compression head 742, the second spring 743 will be compressed, and one end of the telescopic push rod 745 continues to slide in the compression head 742, causing the end of the telescopic push rod 745 to move and form a water spray chamber between the compression head 742. Water flows into the water spray chamber from the drain hole 749, and the end of the telescopic push rod 745 gradually moves, causing the volume of the water spray chamber to gradually increase. Until the volume of the water spray chamber expands to cover the water spray hole 744, high-pressure water is sprayed from the water spray hole 744 to spray and clean the barrel wall of the raw material barrel 2.

[0072] The control system supplies power to the electromagnetic block 1213, and the electromagnetic block 1213 adsorbs the telescopic block 1211, so that the raw material barrel 2 and the limit column 12 are no longer stuck. The control system turns on the first motor 15 and the second motor 84, and the second motor 84 drives the spiral hollow tube 71 to rotate, and the spiral hollow tube 71 drives the scraper 72 thereon to clean the raw material barrel 2. The first motor 15 drives the rotating table 14 to rotate through the gear, and the rotating table 14 drives the raw material barrel 2 to rotate. At this time, the raw material barrel 2 is not affected by the clamping of the limit column 12 and rotates with the rotating table 14. The control system controls the rotation speed of the spiral hollow tube 71 through the electromagnetic reducing ring 81, so that the spiral hollow tube 71 and the raw material barrel 2 rotate through differential rotation or forward and reverse rotation to cooperate with the scraper 72 to clean the barrel wall of the raw material barrel 2, and finally discharge the cleaned sewage, thereby realizing multi-stage self-cleaning of the sterilization equipment.
