Description

Technical Field

[0001] This utility model relates to the field of yogurt processing technology, specifically to a yogurt cooling device. Background Technology

[0002] Yogurt is a fermented dairy product made from fresh milk that has been sterilized and then fermented with lactic acid bacteria. Yogurt is rich in nutrients, and some of the lactose is broken down by lactic acid bacteria during fermentation, which can also alleviate some lactose intolerance symptoms. Therefore, people like to drink yogurt.

[0003] Yogurt processing involves multiple steps, including milk selection, heat sterilization, cooling, and adding starter cultures. Cooling is a crucial step, as it lowers the temperature of the yogurt to provide a suitable temperature for subsequent processing. However, most yogurt cooling devices are tank-type structures, where yogurt is poured into the tank and cooled by cooling pipes installed on the outside. While this method has some cooling effect, it is not very effective at cooling the yogurt in the center of the tank, resulting in uneven cooling between the outside and inside of the tank, and the cooling rate is also low. Therefore, improvements are urgently needed. Utility Model Content

[0004] The purpose of this invention is to provide a yogurt cooling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a yogurt cooling device, comprising a device body, an inlet pipe installed on the outer wall of the bottom of the device body, a first outlet pipe installed on the outer wall of the top of the device body, a perforated partition fixed at the bottom of the device body, and a cooling tank installed inside the device body above the perforated partition. A cooling inner cylinder is fixed at the center of the cooling tank, the top of the cooling inner cylinder extends to the top of the device body, an inlet is provided at the bottom of the cooling tank inside the cooling inner cylinder, discharge pipes are installed on both sides of the bottom of the cooling tank, and a second outlet pipe is installed above the device body.

[0006] Preferably, the second water outlet pipe has an L-shaped structure, and the bottom end of the second water outlet pipe extends into the interior of the cooling inner cylinder.

[0007] Preferably, a circulation pump is installed on one side of the main body of the device, and the input end of the circulation pump is connected to the first outlet pipe and the second outlet pipe respectively.

[0008] Preferably, a lifting frame is provided on the other side of the main body of the device, and a motor is installed inside the lifting frame, and a lead screw is installed at the output end of the motor.

[0009] Preferably, a movable arm is fitted around the lead screw, the movable arm is threadedly engaged with the lead screw, and one end of the movable arm extends to the outside of the lifting frame and is welded with a bracket, and an annular plate is installed at the bottom end of the bracket.

[0010] Preferably, an outer scraping ring is welded to the outer wall of the annular plate, and an inner scraping ring is welded to the inner wall of the annular plate.

[0011] Preferably, the outer scraper ring is in close contact with the inner wall of the cooling tank, and the inner scraper ring is in close contact with the outer wall of the cooling inner cylinder.

[0012] Preferably, the bottom end of the discharge pipe extends to the bottom of the device body and is equipped with a discharge valve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Yogurt is poured into the cooling tank, and cold water is transported to the main body of the device through the inlet pipe. The cold water enters the inner cooling cylinder through the inlet. The cold water located between the cooling tank and the main body of the device cools the yogurt inside the cooling tank from the outside, while the cold water located inside the inner cooling cylinder cools the yogurt inside the cooling tank from the inside. This design optimizes the internal structure of the device. By cooling the yogurt from both the inside and outside simultaneously, the yogurt on the outside and inside can be cooled synchronously. Moreover, heat exchange can be performed on the yogurt in the center, resulting in a fast cooling rate and good cooling effect. Then, the circulating pump extracts the water after heat exchange through the first and second outlet pipes, respectively, so that the cold water inside the main body of the device circulates from bottom to top, carrying away the heat.

[0015] The motor is started to drive the lead screw to rotate, causing the movable arm to move the annular plate down through the bracket. The annular plate scrapes off the yogurt adhering to the inner wall of the cooling tank and the outer wall of the cooling inner cylinder through the outer scraper ring and the inner scraper ring, respectively, until the annular plate descends to the bottom of the cooling tank and squeezes the scraped yogurt out of the discharge pipe, so that the yogurt is discharged cleanly. This design makes it easy to scrape off the yogurt adhering to the inner wall of the device, reducing yogurt waste. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-5 An embodiment of this utility model is provided: a yogurt cooling device, including a device body 1, an inlet pipe 6 installed on the outer wall of the bottom of the device body 1, a first outlet pipe 7 installed on the outer wall of the top of the device body 1, a hollow partition 2 fixed at the bottom of the device body 1, and a cooling tank 3 installed inside the device body 1 above the hollow partition 2.

[0025] A cooling inner cylinder 4 is fixed at the center of the cooling tank 3. The top of the cooling inner cylinder 4 extends to the top of the main body 1 of the device. A water inlet 17 is provided at the bottom of the cooling tank 3 inside the cooling inner cylinder 4. Discharge pipes 15 are installed on both sides of the bottom of the cooling tank 3. A second water outlet pipe 8 is installed on the top of the main body 1 of the device.

[0026] Specifically, the yogurt is poured into the cooling tank 3. Then, the motor 14 is controlled to drive the lead screw 12 to rotate, so that the movable arm 13 drives the annular plate 9 to move down to the top of the cooling tank 3 through the bracket 10. The annular plate 9 seals the opening at the top of the cooling tank 3, which can prevent the yogurt from being contaminated.

[0027] Then, cold water is transported to the inside of the main body 1 of the device through the water inlet pipe 6. At the same time, cold water enters the inside of the cooling inner cylinder 4 through the water inlet 17. The cold water located between the cooling tank 3 and the main body 1 cools the yogurt inside the cooling tank 3 from the outside, and the cold water located inside the cooling inner cylinder 4 cools the yogurt inside the cooling tank 3 from the inside. This design optimizes the internal structure of the device. By cooling the yogurt from the inside and outside at the same time, the yogurt on the outside and inside can be cooled synchronously. Moreover, heat exchange can be carried out on the yogurt in the center, resulting in a fast cooling rate and good cooling effect.

[0028] The circulating pump 5 extracts the heat-exchanged water through the first outlet pipe 7 and the second outlet pipe 8 respectively, so that the cold water inside the main body 1 circulates from bottom to top, carrying away the heat.

[0029] The second water outlet pipe 8 has an L-shaped structure, and the bottom end of the second water outlet pipe 8 extends into the interior of the cooling inner cylinder 4; a circulation pump 5 is installed on one side of the main body 1 of the device, and the input end of the circulation pump 5 is connected to the first water outlet pipe 7 and the second water outlet pipe 8 respectively.

[0030] A lifting frame 11 is provided on the other side of the main body 1 of the device, and a motor 14 is installed inside the lifting frame 11, and a lead screw 12 is installed at the output end of the motor 14; a movable arm 13 is fitted on the outside of the lead screw 12, the movable arm 13 is threadedly engaged with the lead screw 12, and one end of the movable arm 13 extends to the outside of the lifting frame 11 and is welded with a bracket 10, and an annular plate 9 is installed at the bottom end of the bracket 10.

[0031] An outer scraper ring 901 is welded to the outer wall of the annular plate 9, and an inner scraper ring 902 is welded to the inner wall of the annular plate 9; the outer scraper ring 901 is tightly fitted to the inner wall of the cooling tank 3, and the inner scraper ring 902 is tightly fitted to the outer wall of the cooling inner cylinder 4.

[0032] Specifically, the discharge valve 16 is opened to allow the yogurt inside the cooling tank 3 to be discharged through the circulation pump 5. Then, the motor 14 is started to drive the lead screw 12 to rotate, so that the movable arm 13 drives the annular plate 9 to continue to move down through the bracket 10. The annular plate 9 scrapes off the yogurt adhering to the inner wall of the cooling tank 3 and the outer wall of the cooling inner cylinder 4 through the outer scraper ring 901 and the inner scraper ring 902 respectively, until the annular plate 9 descends to the bottom of the cooling tank 3 and squeezes the scraped yogurt out from the discharge pipe 15, so that the yogurt is completely discharged. This design makes it easy to scrape off the yogurt adhering to the inner wall of the device and reduces the waste of yogurt.

[0033] The bottom end of the discharge pipe 15 extends to the bottom of the main body 1 of the device and is equipped with a discharge valve 16.

[0034] In this embodiment, the following steps are taken during use: First, yogurt is poured into the cooling tank 3. Second, the motor 14 is controlled to drive the lead screw 12 to rotate, causing the movable arm 13 to move the annular plate 9 down to the top of the cooling tank 3 via the bracket 10. The annular plate 9 seals the opening at the top of the cooling tank 3, preventing contamination of the yogurt. Then, cold water is supplied to the device body 1 through the water inlet pipe 6. Simultaneously, cold water enters the cooling inner cylinder 4 through the water inlet 17. The cold water located between the cooling tank 3 and the device body 1 cools the yogurt inside the cooling tank 3 from the outside, while the cold water located inside the cooling inner cylinder 4 cools the yogurt inside the cooling tank 3 from the inside. This design optimizes the internal structure of the device, allowing for simultaneous cooling of the yogurt from both the inside and outside. The device can exchange heat and cool the yogurt in the center, with a fast cooling rate and good cooling effect. Then, the circulating pump 5 extracts the water after heat exchange through the first water outlet pipe 7 and the second water outlet pipe 8, so that the cold water inside the main body 1 circulates from bottom to top, carrying away the heat. Finally, the discharge valve 16 is opened so that the yogurt inside the cooling tank 3 is discharged through the circulating pump 5. Then, the motor 14 is started to drive the lead screw 12 to rotate, so that the movable arm 13 drives the annular plate 9 to continue to move down through the bracket 10. The annular plate 9 scrapes off the yogurt attached to the inner wall of the cooling tank 3 and the outer wall of the cooling inner cylinder 4 through the outer scraper ring 901 and the inner scraper ring 902, until the annular plate 9 descends to the bottom of the cooling tank 3 and squeezes the scraped yogurt out of the discharge pipe 15, so that the yogurt is discharged cleanly. This design makes it easy to scrape off the yogurt adhering to the inner wall of the device and reduces the waste of yogurt.

[0035] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
