Description

Technical Field

[0001] This application relates to the field of food processing technology, and in particular to a cold shock treatment apparatus for the production of fermented cream. Background Technology

[0002] The cold shock treatment device for fermented cream production inhibits excessive microbial growth during fermentation by rapidly cooling the product, precisely controlling the fermentation process to ensure stable acidity, texture, and other indicators of the cream, while preserving its flavor and nutrients. It avoids rancidity or texture deterioration caused by over-fermentation, improving product taste and consistency. It also enables and shortens the production cycle, reducing human intervention through precise temperature control, making it suitable for industrial-scale mass production.

[0003] The cold shock treatment device for fermented cream production rapidly lowers the temperature of the heat exchange medium using cooling water, which is then piped to the jacket of the fermentation tank or agitator for direct or indirect heat exchange with the cream. This causes the system temperature to drop sharply from the fermentation temperature to 2-5°C within a short time, inhibiting microbial enzyme activity and metabolic rate, and controlling fermentation efficiency. It is suitable for industrial-scale fermented cream production in dairy companies, and can effectively control the fermentation time and extent when the reaction needs to be terminated immediately after the fermentation endpoint is determined.

[0004] In existing technologies, some cold shock treatment devices for fermented cream production only achieve heat exchange and cold shock treatment by introducing cooling water into the interior of the fermentation tank jacket. However, during the heat exchange process, the cooling water temperature rises over a long period, leading to a decrease in cold shock efficiency. This makes it difficult to accurately control the fermentation efficiency and degree, resulting in fermentation failure. To address this issue, an automatic feeding device for a carton printing machine is proposed. Utility Model Content

[0005] The purpose of this application is to provide a cold shock treatment device for the production of fermented cream, which aims to improve the problem that when cooling water undergoes heat exchange, the temperature of the cooling water will rise during long-term heat exchange, resulting in a decrease in cold shock efficiency, which makes it difficult to accurately control the efficiency and degree of fermentation and causes fermentation failure.

[0006] The cold shock treatment apparatus for producing fermented light cream provided in this application adopts the following technical solution:

[0007] A cold shock treatment device for the production of fermented cream includes a reaction vessel, a temperature control mechanism installed on the outer wall of the reaction vessel, a thermistor fixedly connected to the inner wall of the reaction vessel, a drive motor fixedly connected to the bottom of the reaction vessel, a stirring rod fixedly connected to the drive end of the drive motor, and an anti-clogging mechanism installed on the top of the stirring rod.

[0008] The temperature control mechanism includes a fixed plate, the outer wall of which is fixedly connected to the outer wall of the reactor. A circulation assembly is fixedly connected to the top of the fixed plate. A water pump is fixedly connected to the outer wall of the reactor. A spiral tube is fixedly connected to the output end of the water pump. A spiral heating tube is fixedly connected to the bottom of the reactor.

[0009] The above technical solution involves a temperature-sensitive resistor that monitors the temperature inside the reactor in real time and feeds it back to the control system. A drive motor drives an anti-clogging mechanism via a stirring rod. The temperature control mechanism regulates the temperature through cooling water circulation in the spiral tube or a spiral heating tube. This forms an automated processing system that integrates temperature monitoring, stirring and anti-clogging, and hot and cold control, ensuring that fermented thin yogurt is produced in a suitable temperature environment and improving processing efficiency and stability.

[0010] Preferably, the anti-clogging mechanism includes a fixed box, the top of which is fixedly connected to the bottom of the reactor. The outer wall of the stirring rod is rotatably connected to the inner wall of the fixed box. A driving bevel gear is fixedly connected to the top of the stirring rod, and a transmission bevel gear is rotatably connected to the inner wall of the fixed box. The outer side of the transmission bevel gear is meshed with the outer side of the driving bevel gear. A stirring blade is fixedly connected to one end of the transmission bevel gear.

[0011] By adopting the above technical solution, when the stirring rod rotates, it drives the active bevel gear to rotate synchronously. The active bevel gear drives the transmission bevel gear to rotate through meshing transmission, which in turn drives the stirring blade to stir the material near the discharge port in the fixed box. The mechanical stirring breaks the tendency of the material to clump together, prevents the fermented thin yogurt from accumulating and blocking the bottom of the reactor, ensures a smooth and continuous feeding process, and improves production continuity.

[0012] Preferably, a feed pipe is fixedly connected to the inner wall of the reactor, and a metering valve is fixedly connected inside the feed pipe.

[0013] By adopting the above technical solution, the quantitative feeding valve can accurately control the feeding flow of fermented thin yogurt according to the production process requirements. The quantitative output can be achieved by adjusting the valve opening degree or the opening and closing frequency, avoiding the randomness and error of manual feeding, meeting the precise control requirements of material input at different production stages, and improving the standardization and controllability of the production process.

[0014] Preferably, the outer wall of the feeding pipe is fixedly connected to the inner wall of the fixed box, and the stirring blade is rotatably connected to the inner wall of the feeding pipe.

[0015] By adopting the above technical solution, the feeding pipe is fixed inside the fixed box, allowing the stirring blade to directly extend into the inner cavity of the feeding pipe and rotate, shortening the distance between the stirring point and the feeding port, and enhancing the disturbance effect on the material inside the feeding pipe; the rotation trajectory of the stirring blade is perpendicular to the feeding direction, which can effectively disperse the sticky material, while the closed structure of the fixed box reduces material splashing during the stirring process, improving the targeting and reliability of the anti-clogging function.

[0016] Preferably, the circulation assembly includes a cooling device, the bottom of which is fixedly connected to the top of the fixed plate, and a circulation box is fixedly connected to the top of the fixed plate.

[0017] By adopting the above technical solution, the cooling device provides a low-temperature refrigerant, and the circulation box serves as a temporary storage and cooling container for cooling water. The two are integrated into the outer wall of the reactor through a fixing plate to form an independent circulating cooling module. When the cooling water in the spiral tube absorbs heat and rises in temperature, it can be transported to the circulation box by the circulation pump for cooling treatment, thereby realizing the recycling of the cooling medium, reducing energy consumption and ensuring continuous cooling capacity.

[0018] Preferably, a transmission pipe is fixedly connected to the output end of the cooling device, and multiple heat dissipation fins are fixedly connected to the inner wall of the circulation box.

[0019] By adopting the above technical solution, the low-temperature refrigerant output by the cooling device is introduced into the circulation box through the transmission pipe. The heat dissipation fins are distributed in a dense array on the inner wall of the circulation box, increasing the heat exchange area between the refrigerant and the cooling water. When the high-temperature cooling water flows in the circulation box, the heat is conducted to the heat dissipation fins through the wall of the transmission pipe and then absorbed and carried away by the refrigerant, which significantly improves the cooling efficiency and ensures that the cooling water returning to the spiral tube maintains a low temperature and maintains a stable cooling effect.

[0020] Preferably, one end of the transmission tube is fixedly connected to the inner wall of the spiral tube, and a circulation pump is fixedly connected to the outer wall of the circulation box.

[0021] By adopting the above technical solution, one end of the transmission pipe is connected to the outlet of the spiral tube, and the other end is connected to the circulation box, forming a return channel for cooling water from the reactor to the circulating cooling module; the circulation pump provides power to drive the cooling water to circulate. When the temperature of the cooling water in the spiral tube rises, the circulation pump draws it into the circulation box to cool it down, and the cooled cooling water is then re-injected into the spiral tube by the water pump.

[0022] Preferably, the inner wall of the reactor is provided with a hollow groove, and the outer wall of the spiral tube is fixedly connected to the inner wall of the hollow groove.

[0023] By adopting the above technical solution, the spiral tube is embedded in the hollow groove of the inner wall of the reactor, and its outer wall is closely attached to the inner wall of the hollow groove, so as to maximize the contact area between the spiral tube and the fermenting dilute yogurt in the reactor. When the cooling water flows in the spiral tube, it exchanges heat with the material through the tube wall. The spiral shape of the spiral tube extends the water flow path, which can further enhance the convective heat transfer effect and make the temperature control more uniform and efficient.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Cooling water is pumped into the inner wall of the spiral tube to cool the material inside. Then, the circulation pump is started to pump the cooling water inside the spiral tube into the inner wall of the circulation box. The refrigerant inside the cooling device is transferred to the inner wall of the transmission pipe inside the circulation box. The heat is transferred to the cooling water inside the circulation box through the heat dissipation fins to facilitate cooling. Then, the cooling water is circulated into the inner wall of the spiral tube again to further cool the fermented thin yogurt inside.

[0026] 2. The start of the drive motor causes the stirring rod to rotate. The rotation of the stirring rod causes the top drive bevel gear to rotate. The rotation of the drive bevel gear causes the transmission bevel gear to rotate. The rotation of the transmission bevel gear causes the stirring blade to rotate. The rotation of the stirring blade causes the material to be stirred during the feeding pipe, preventing blockage during feeding. Attached Figure Description

The temperature control mechanism 2 includes a fixing plate 24, the outer wall of which is fixed to the outer wall of the reactor 1 for installing and fixing a circulation component 25. The circulation component 25 can circulate and cool the cooling water for reuse. Together with a water pump 21, a spiral tube 22, a spiral heating tube 23, etc., it can cool or heat the material in the reactor 1. The anti-blocking mechanism 5 drives the stirring blade 54 to rotate through gear transmission and works with a quantitative feed valve 55 to control the feed amount.

[0035] A circulation assembly 25 is fixedly connected to the top of the fixed plate 24. The circulation assembly 25 can circulate and cool the cooling water for reuse. A water pump 21 is fixedly connected to the outer wall of the reactor 1. The water pump 21 can draw cooling water into the inner wall of the spiral tube 22. The output end of the water pump 21 is fixedly connected to the spiral tube 22. The spiral tube 22 can exchange heat with the material in the reactor 1 through the internally flowing cooling water to achieve cooling. A spiral heating tube 23 is fixedly connected to the bottom of the reactor 1. The spiral heating tube 23 can heat the material in the reactor 1 when needed.

The bottom of the cooling device 251 is fixedly connected to the top of the fixed plate 24. A circulation box 254 is fixedly connected to the top of the fixed plate 24. The circulation box 254 is used to contain the cooling water to be cooled and exchange heat with the refrigerant.

[0036] Specifically, the circulation assembly 25 fixed to the top of the fixed plate 24 can circulate and cool the cooling water for reuse. The water pump 21 on the outer wall of the reactor 1 draws the cooling water into the inner wall of the spiral tube 22. The spiral tube 22 cools down by exchanging heat with the material in the reactor 1 through the internally flowing cooling water. The spiral heating tube 23 at the bottom can heat up the material when needed. The circulation assembly 25 includes a cooling device 251 and a circulation box 254. The cooling device 251 provides refrigerant for cooling the water, and its bottom is fixed to the top of the fixed plate 24. The circulation box 254 is fixed to the top of the fixed plate 24 and is used to hold the cooling water to be cooled. By exchanging heat with the refrigerant through the transmission pipe 252 and the heat dissipation fins 253, the heated cooling water is cooled down, ensuring that the cooling water can be circulated back into the spiral tube 22 for reuse, thus optimizing the temperature control efficiency.

[0037] The output end of the cooling device 251 is fixedly connected to a transmission pipe 252, which can transport the refrigerant to the inside of the circulation box 254. The inner wall of the circulation box 254 is fixedly connected to multiple heat dissipation fins 253, which can increase the heat exchange area between the refrigerant and the cooling water to improve the cooling efficiency. One end of the transmission pipe 252 is fixedly connected to the inner wall of the spiral tube 22, which allows the cooled water in the spiral tube 22 to flow into the circulation box 254 after being heated. The outer wall of the circulation box 254 is fixedly connected to a circulation pump 255, which can pump the cooled water back into the spiral tube 22 to achieve circulation. The inner wall of the reactor 1 is provided with a hollow groove 26, which provides installation space for the spiral tube 22. The outer wall of the spiral tube 22 is fixedly connected to the inner wall of the hollow groove 26, so that the spiral tube 22 can fit tightly against the inner wall of the reactor 1 to optimize the heat exchange effect.

[0038] Specifically, the output end of the cooling device 251 delivers refrigerant to the inside of the circulation box 254 through the transmission pipe 252. Multiple heat dissipation fins 253 on the inner wall of the circulation box 254 increase the heat exchange area between the refrigerant and the cooling water, thereby improving the cooling efficiency. One end of the transmission pipe 252 is connected to the inner wall of the spiral tube 22, allowing the heated cooling water in the spiral tube 22 to flow into the circulation box 254. After cooling, the water is drawn back into the spiral tube 22 by the circulation pump 255 on the outer wall of the circulation box 254, thus achieving cooling water circulation. A hollow groove 26 is opened in the inner wall of the reactor 1 to provide installation space for the spiral tube 22. The outer wall of the spiral tube 22 is fixed to the inner wall of the hollow groove 26, so that it fits tightly against the inner wall of the reactor 1, optimizing the heat exchange effect with the internal materials and ensuring the stability and efficiency of temperature control.

[0039] Reference Figures 2 to 4 The anti-clogging mechanism 5 includes a fixed box 51, which is used to install and fix the transmission components. The top of the fixed box 51 is fixedly connected to the bottom of the reactor 1. The outer wall of the stirring rod 4 is rotatably connected to the inner wall of the fixed box 51, so that the stirring rod 4 can rotate stably inside the fixed box 51. The top of the stirring rod 4 is fixedly connected to a drive bevel gear 52, which can rotate with the stirring rod 4 and drive the transmission bevel gear 53 to rotate. The inner wall of the fixed box 51 is rotatably connected to the transmission bevel gear 53, which can rotate under the drive of the drive bevel gear 52.

One end of the transmission bevel gear 53 is fixedly connected to a stirring blade 54, which can stir the material in the feed pipe 6 under the drive of the transmission bevel gear 53.

[0040] Specifically, the anti-clogging mechanism 5 consists of a fixed box 51 and a transmission component. The top of the fixed box 51 is fixed to the bottom of the reactor 1 and is used to install and fix the transmission component. The outer wall of the stirring rod 4 is rotatably connected to the inner wall of the fixed box 51 to ensure its stable rotation. The active bevel gear 52 at the top of the stirring rod 4 rotates with the stirring rod 4. Through the meshing of the transmission bevel gear 53 rotatably connected to the inner wall of the fixed box 51, the power is transmitted. The transmission bevel gear 53 drives the stirring blade 54 at one end to rotate, stirring the material in the feed pipe 6. This mechanism transmits the power of the drive motor 3 driving the stirring rod 4 to rotate to the stirring blade 54 in the feed pipe 6 through the gear transmission structure, so that the material remains in a flowing state during the feeding process, effectively preventing the feed pipe 6 from being blocked due to material accumulation, and ensuring the smoothness of the feeding process.

The outer wall of the feed pipe 6 is fixedly connected to the inner wall of the fixed box 51, so that the feed pipe 6 and the anti-blocking mechanism 5 form a stable structure. The stirring blade 54 is rotatably connected to the inner wall of the feed pipe 6. The rotation of the stirring blade 54 can prevent the material from accumulating and blocking in the feed pipe 6.

[0042] Specifically, the inner wall of the reactor 1 is fixed with a feed pipe 6 for discharging materials. The quantitative feed valve 55 inside the feed pipe 6 can control the amount of material to be discharged as needed. The outer wall of the feed pipe 6 is fixed to the inner wall of the fixed box 51, forming a stable structure with the anti-blocking mechanism 5. The stirring blade 54, which is rotatably connected to the inner wall, can prevent material from accumulating and blocking by rotating, thus ensuring smooth material discharge.

[0043] Working principle: When it is necessary to perform a cooling shock treatment on the fermented diluted yogurt inside the reactor 1, cooling water is pumped into the inner wall of the spiral tube 22 by the water pump 21. At this time, the drive motor 3 starts, and the rotation of the drive motor 3 drives the stirring rod 4 to rotate and stir the fermented diluted yogurt on the inner wall. During use, the temperature of the cooling water inside the spiral tube 22 will rise due to temperature exchange between the fermented diluted yogurt, reducing the effectiveness of the cooling water. At this time, the circulation pump 255 is started to pump the cooling water inside the spiral tube 22 into the inner wall of the circulation box 254 for cooling. The refrigerant inside device 251 is transferred to the inner wall of the transmission pipe 252 inside the circulation box 254, and then the heat is further transferred to the cooling water inside the circulation box 254 through the heat dissipation fins 253 to facilitate the cooling of the internal cooling water. Then the cooling water is once again introduced into the inner wall of the spiral tube 22 to facilitate better cooling of the fermented thin yogurt inside. It is used to detect the temperature inside the reactor 1. When it is necessary to raise the temperature of the fermented thin yogurt inside the reactor 1, the spiral heating tube 23 is activated to raise the temperature, and the temperature-sensitive resistor 7 is used to regulate the temperature.

[0044] When feeding the fermented thin yogurt, the start of the drive motor 3 drives the stirring rod 4 to rotate. The rotation of the stirring rod 4 drives the top active bevel gear 52 to rotate. The rotation of the active bevel gear 52 drives the transmission bevel gear to rotate. The rotation of the transmission bevel gear drives the stirring blade 54 to rotate. The rotation of the stirring blade 54 causes the feeding pipe 6 to stir the material during feeding, preventing blockage. The quantitative feeding valve 55 is used to control the quantitative feeding of the fermented thin yogurt, thereby realizing feeding according to the actual situation.
