Description

Technical Field

[0001] This utility model relates to the field of dairy product sterilization and processing technology, specifically to a dairy product sterilization device that provides convenient and rapid cooling. Background Technology

[0002] Dairy products refer to various foods made primarily from cow's or goat's milk and their processed products, with or without the addition of appropriate amounts of vitamins, minerals, and other excipients, and processed under conditions required by laws, regulations, and standards. During the production and processing of dairy products, strict sterilization treatment is essential to ensure food safety and extend shelf life. Currently, commonly used sterilization methods for dairy products include pasteurization and ultra-high temperature (UHT) sterilization. UHT sterilization is widely used because it can kill bacteria in a short time while preserving the nutritional components of dairy products to the greatest extent.

[0003] Sterilized dairy products typically reach temperatures of 135-150℃ and require rapid cooling to 20-30℃ before entering the subsequent filling process. Traditional cooling structures often employ single water-cooled jackets or air cooling methods, resulting in low cooling efficiency and extended production cycles. Furthermore, uneven temperature distribution can occur during the cooling process, and incomplete cooling in some areas may affect product quality.

[0004] Furthermore, the energy utilization rate of sterilization equipment is low. After the sterilization operation is completed, a large amount of high-temperature steam will remain in the high-temperature sterilization tank. This heat-rich steam is not easy to recover and reuse, resulting in waste of residual heat. At the same time, subsequent sterilization operations still need to rely on the heating module to heat the dairy products from scratch, which further increases energy consumption and energy costs in the production process.

[0005] Therefore, we propose a convenient and rapid cooling sterilization device for dairy products to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a dairy product sterilization device that provides convenient and rapid cooling, thereby solving the problems of uneven cooling and difficulty in recovering residual heat generated in high-temperature sterilization chambers in existing sterilization devices mentioned in the background art.

[0007] This utility model provides the following technical solution: a dairy product sterilization device that facilitates rapid cooling, including a high-temperature sterilization tank and a support tank, wherein a waste heat recovery component is installed on the end side of the high-temperature sterilization tank, a conveying pipe is connected to the end side of the high-temperature sterilization tank, a fixing plate is fixed on the end side of the high-temperature sterilization tank, and a conveying pump is installed on the fixing plate; A cooling tank is installed inside the support tank, and the cooling tank is connected to the conveying pipe. A stirring assembly is installed inside the cooling tank. A cooling assembly is provided on the support tank. A filter assembly is provided inside the cooling tank. A discharge pipe is connected to the bottom of the cooling tank, and a drain valve is installed inside the discharge pipe.

[0008] Preferably, the waste heat recovery assembly includes an exhaust pipe connected to the top of the high-temperature sterilization tank, a water storage tank connected to the bottom of the exhaust pipe, a water supply pipe connected to the water storage tank, a water pump installed on the water supply pipe, and a solenoid valve installed on the exhaust pipe.

[0009] Preferably, a spiral water pipe is wound around the outer ring of the high-temperature sterilization tank, one end of which is connected to a water supply pipe and the other end of which is connected to a water storage tank.

[0010] Preferably, the stirring assembly includes a motor fixed to the cooling tank, a drive shaft fixed to the output end of the motor, a rotating shaft fixed to the bottom of the drive shaft, and a stirring rod fixed to the outer ring of the rotating shaft.

[0011] Preferably, the stirring rod is arranged in a U-shape, and the stirring rod rotates in contact with the inner wall of the cooling tank.

[0012] Preferably, the cooling assembly includes a sleeve fixed to the outer ring of the support tank, a condensate tank fixed on the sleeve, a water inlet pipe connected to the condensate tank, and a control valve installed on the water inlet pipe.

[0013] Preferably, the bottom of the condensate tank is connected to a water outlet pipe, a control valve is installed on the water outlet pipe, and a spiral condenser tube is wound around the outer ring of the cooling tank, with the two ends of the spiral condenser tube connected to the water inlet pipe and the water outlet pipe, respectively.

[0014] Preferably, the filter assembly includes a slot formed at the bottom of the cooling tank, a filter screen is engaged in the slot, the filter screen has an insertion hole, a bolt is threaded into the insertion hole, the bolt is threaded to the cooling tank, and a hexagonal groove is formed on the top of the bolt.

[0015] This utility model has the following beneficial effects: 1. This device can improve the cooling effect and efficiency of high-temperature dairy products after sterilization. By using the stirring component and the cooling component together, the stirring component stirs the dairy products in the cooling tank in all directions, and the cooling component achieves continuous and stable cooling. It can break the temperature stratification that is prone to occur during the cooling process of dairy products, effectively avoid the problem of incomplete local cooling, accelerate the cooling speed from high temperature to target temperature, and ensure the overall cooling uniformity. It solves the problem of low efficiency of traditional single cooling methods and effectively shortens the dairy product processing cycle.

[0016] 2. This device can efficiently recover residual heat during the sterilization process of dairy products. Addressing the problem of large amounts of residual high-temperature steam remaining after high-temperature sterilization tank operations and the difficulty in recovering it, the waste heat recovery component precisely collects the heat from the residual steam inside the tank and efficiently transfers it to cold water in the storage tank. The heated water can be directly used for the preheating stage of subsequent sterilization operations, eliminating the need for subsequent dairy products to be heated from zero using a heating module. This significantly reduces the energy consumption of the heating module, achieves heat recycling, fundamentally solves the problem of waste heat, and reduces energy costs in the production process.

[0017] 3. This device effectively improves the quality of dairy product processing. The filter components inside the cooling tank can intercept tiny impurities remaining in the sterilized dairy products, ensuring the purity of the discharged dairy products and reducing the impact of impurities on subsequent processing stages. Meanwhile, the filter screen uses a combination of snap-fit ​​and bolt-fixed structure, making replacement simple and quick, restoring filtration efficiency promptly, and eliminating the need to disassemble the main cooling tank, thus reducing equipment maintenance difficulty and costs.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: This embodiment aims to help solve the problems of wasteful residual heat and high energy consumption during the sterilization process of dairy products. Please refer to [link / reference]. Figure 1 - Figure 6 A convenient and rapid cooling dairy product sterilization device includes a high-temperature sterilization tank 1 and a supporting tank 2. A waste heat recovery component 3 is installed on one end of the high-temperature sterilization tank 1. The high-temperature sterilization tank 1 has an inlet for feeding the dairy products to be sterilized. The structure and usage of this inlet are existing technology and will not be described in detail. A conveying pipe 4 is connected to one end of the high-temperature sterilization tank. A fixing plate 5 is fixed to one end of the high-temperature sterilization tank 1, and a conveying pump 6 is installed on the fixing plate 5. A cooling tank 7 is installed inside the supporting tank 2. The cooling tank 7 is equipped with an inspection door, allowing personnel to easily open the door to clean the inner wall of the cooling tank 7 or replace relevant components. Since the structure and opening method of the inspection door are known technology, they will not be described in detail. The cooling tank 7 is connected to the conveying pipe 4, and a discharge pipe 11 is connected to the bottom of the cooling tank 7. A drain valve 12 is installed inside the discharge pipe 11.

[0027] The waste heat recovery assembly 3 includes an exhaust pipe 31 connected to the top of the high-temperature sterilization tank 1, a water storage tank 32 connected to the bottom of the exhaust pipe 31, a water supply pipe 33 connected to the water storage tank 32, a water pump 34 installed on the water supply pipe 33, a solenoid valve 36 installed on the exhaust pipe 31, and a spiral water pipe 35 wound around the outer ring of the high-temperature sterilization tank 1. One end of the spiral water pipe 35 is connected to the water supply pipe 33, and the other end of the spiral water pipe 35 is connected to the water storage tank 32.

[0028] In this embodiment: When using this sterilization device to perform high-temperature sterilization on dairy products, the dairy products to be sterilized are first poured into the high-temperature sterilization tank 1. Then, the heating module of the high-temperature sterilization tank 1 heats the dairy products in the tank to raise the temperature to the high-temperature threshold required for sterilization of dairy products (such as 60-85℃ commonly used for pasteurization or 135-150℃ for ultra-high temperature instantaneous sterilization), and maintains the temperature for the corresponding time to achieve the sterilization effect. This heating and temperature control process is existing technology and will not be described in detail.

[0029] After the high-temperature sterilization process is completed, the solenoid valve 36 on the exhaust pipe 31 is opened. The high-temperature steam remaining inside the high-temperature sterilization tank 1 will rise into the exhaust pipe 31 due to the pressure difference. Then the steam will be transported down the exhaust pipe 31 to the water storage tank 32, where it will come into full contact with the cold water stored in the water storage tank 32. The heat of the steam will be absorbed by the cold water, achieving efficient recovery of residual heat.

[0030] After absorbing heat, the water is heated to form warm water. When the dairy products are sterilized again, the water pump 34 on the water supply pipe 33 can be started to transport the warm water in the storage tank 32 through the water supply pipe 33 to the spiral water pipe 35 wrapped around the outer ring of the high-temperature sterilization tank 1. During the flow of the warm water in the spiral water pipe 35, it can preheat the dairy products in the high-temperature sterilization tank 1, effectively reducing the energy consumption of the heating module and completing the heat recycling. After preheating, the water in the spiral water pipe 35 flows back to the storage tank 32 for the next use. The sterilized dairy products can be transported to the cooling tank 7 through the delivery pipe 4 by starting the delivery pump 6 for cooling treatment. After cooling, the drain valve 12 on the discharge pipe 11 can be opened to complete the discharge.

[0031] Example 2: This embodiment aims to address the issues of slow and uneven cooling of dairy products after sterilization. It is an improvement upon Embodiment 1. For details, please refer to [link to Embodiment 1]. Figure 1 - Figure 6 The cooling tank 7 is equipped with a stirring assembly 8, and the support tank 2 is equipped with a cooling assembly 9. The stirring assembly 8 includes a motor 81 fixed on the cooling tank 7. A transmission shaft 82 is fixed at the output end of the motor 81. A rotating shaft 83 is fixed at the bottom of the transmission shaft 82. A stirring rod 84 is fixed on the outer ring of the rotating shaft 83. The stirring rod 84 is arranged in a U-shaped frame and rotates in contact with the inner wall of the cooling tank 7.

[0032] The cooling assembly 9 includes a sleeve 91 fixed to the outer ring of the support tank 2. A condensate tank 92 is fixed on the sleeve 91. An inlet pipe 93 is connected to the condensate tank 92. A control valve 94 is installed on the inlet pipe 93. An outlet pipe 96 is connected to the bottom of the condensate tank 92. A control valve 97 is installed on the outlet pipe 96. A spiral condenser tube 95 is wound around the outer ring of the cooling tank 7. The two ends of the spiral condenser tube 95 are connected to the inlet pipe 93 and the outlet pipe 96, respectively.

[0033] In this embodiment: after the dairy products in the high-temperature sterilization tank 1 have been sterilized, the transfer pump 6 is started, which can accurately transfer the sterilized dairy products in the high-temperature sterilization tank 1 to the cooling tank 7.

[0034] At this time, the motor 81 of the stirring assembly 8 and the control valve 94 and control valve 97 of the cooling assembly 9 are started simultaneously. After the motor 81 starts running, it drives the transmission shaft 82 at the output end to rotate. The transmission shaft 82 further drives the bottom rotating shaft 83 to rotate synchronously. The U-shaped frame stirring rod 84 fixed on the outer ring of the rotating shaft 83 rotates together with the rotating shaft 83.

[0035] Because the stirring rod 84 is in close contact with the inner wall of the cooling tank 7, it can not only stir the dairy products in the cooling tank 7 in all directions during the rotation process, breaking the temperature stratification inside the dairy products and effectively avoiding the problem of insufficient local cooling; it can also scrape off the dairy products attached to the inner wall of the cooling tank 7 to prevent residue from sticking and affecting subsequent equipment cleaning.

[0036] At the same time, after the control valve 94 is opened, the low-temperature condensate in the condensate tank 92 flows into the spiral condenser tube 95 wrapped around the outer ring of the cooling tank 7 through the water inlet pipe 93. When the condensate flows in the spiral condenser tube 95, it exchanges heat efficiently with the dairy products inside the cooling tank 7 through the tank wall, and quickly absorbs the heat of the dairy products to achieve cooling.

[0037] By synchronously controlling control valve 94 and control valve 97, the condensate in the spiral condenser 95 and the condensate tank 92 forms a stable circulation flow, continuously providing a low-temperature cooling source for the cooling tank 7, thereby achieving rapid and continuous cooling of the dairy products in the cooling tank 7, improving the cooling speed and uniformity of the dairy products, and effectively shortening the overall processing cycle.

[0038] Example 3: This embodiment aims to address the issue of potential residual impurities in sterilized dairy products, which could affect the quality of dairy processing. This embodiment is an improvement upon Embodiment 1. For details, please refer to [link to Embodiment 1]. Figure 4 - Figure 5The cooling tank 7 is equipped with a filter assembly 10. The filter assembly 10 includes a slot 101 at the bottom of the cooling tank 7. A filter screen 102 is snapped into the slot 101. The filter screen 102 has an insertion hole 103. A bolt 104 is threaded into the insertion hole 103. The bolt 104 is threadedly connected to the cooling tank 7. A hexagonal groove 105 is provided on the top of the bolt 104.

[0039] In this embodiment: After the sterilized dairy products enter the cooling tank 7 through the conveying pipe 4 for cooling treatment, they need to be discharged. When the dairy products are discharged, they first flow through the filter screen 102 at the bottom of the cooling tank 7. The filter screen 102 can effectively intercept any small impurities that may remain in the dairy products, such as a small amount of milk protein coagulation particles generated during the sterilization process, to ensure the purity of the final discharged dairy products.

[0040] When filter 102 becomes clogged or its filtration efficiency decreases after long-term use and needs to be replaced, the operator can open the access door of the cooling tank 7, insert a hex wrench into the hexagonal groove 105 on the top of bolt 104, and rotate the wrench clockwise to rotate bolt 104. Since bolt 104, filter 102, and cooling tank 7 are all threaded, the bolt 104 can be unscrewed to release the fixation of filter 102.

[0041] The old filter screen 102 is then removed directly from the slot 101 at the bottom of the cooling tank 7. The new filter screen 102 is then aligned with the slot 101 and snapped into place. Finally, the bolt 104 is passed through the insertion hole 103 on the filter screen 102 and tightened with the threads of the cooling tank 7, completing the quick replacement of the filter screen 102. The entire filtration and replacement process is simple to operate, requiring no disassembly of the main structure of the cooling tank 7, thus ensuring the filtration effect of dairy products while reducing equipment maintenance costs.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
