Description

Technical Field

[0001] This utility model relates to the field of fermented milk production technology, specifically to a milk storage tank device for fermented milk production. Background Technology

[0002] Fermented milk is a dairy product made through fermentation with specific lactic acid bacteria. Rich in probiotics and nutrients, it is increasingly favored by consumers. Fermented milk not only has a unique taste but also positively promotes the digestive and immune systems. With growing emphasis on healthy eating, the market demand for fermented milk is constantly increasing, driving innovation in its production processes and equipment. To ensure the quality and safety of fermented milk, the design and function of milk storage tanks are particularly important during production. These tanks must not only meet the storage requirements of milk during fermentation but also possess excellent stirring, temperature control, and hygiene properties to guarantee the quality of the final product.

[0003] Utility model patent CN217497285U discloses a milk storage tank, including a tank body. A motor is fixedly installed on the top of the tank body, and a shaft is fixedly connected to the output end of the motor. A first gear is fixedly installed on the outer side of the shaft, and a second gear is meshed with the outer surface of the first gear. A movable rod is fixedly installed on the inner side of the second gear. A first stirring rod is fixedly connected to the outer side of the shaft, and a second stirring rod is fixedly installed on the outer side of the movable rod. The beneficial effect of this utility model is that, through the operation of the motor, the shaft drives the first stirring rod to rotate, initially stirring the milk inside the tank. Then, through the cooperation of the first and second gears, the movable rod drives the second stirring rod to rotate, further stirring the milk inside the tank, resulting in a uniform concentration of the discharged milk. This structure ensures a uniform concentration of the milk used.

[0004] Although the aforementioned technology ensures uniform milk concentration by stirring the milk within the tank, the presence of a second baffle inside the tank means that material can enter the space below the baffle when the flow pipe discharges, resulting in residue in that space. Prolonged residue not only leads to spoilage but may also come into contact with spoiled material during subsequent discharges, posing a safety hazard. To effectively address this issue, we propose a milk storage tank device for fermented milk production, designed to improve safety and ensure the quality of fermented milk products. Utility Model Content

[0005] The purpose of this invention is to provide a milk storage tank device for fermented milk production, so as to solve the problems mentioned in the background art.

[0028] Please see Figures 1-5 This utility model provides a technical solution:

[0029] A milk storage tank device for fermented milk production includes a tank body 100 for storing fermented milk. The top of the tank body 100 is equipped with a tank cover 200, and the top of the tank cover 200 is equipped with a feeding pipe 210 with a sealing cap.

A rotating vertical rod 500 is rotatably connected to the U-shaped fixing plate 400, and a permanent magnet rotor 800 is located at the bottom of the rotating vertical rod 500. The permanent magnet rotor 800 and the copper rotor 110... The system utilizes a non-contact magnetic drive mechanism. Multiple horizontal stirring rods 600, arranged equidistantly vertically, are mounted on the outer wall of the rotating vertical rod 500. These horizontal stirring rods 600 horizontally stir the fermented milk to improve uniformity. Multiple horizontal stirring rods 600 are connected to multiple vertical stirring rods 700 arranged equidistantly horizontally. These vertical stirring rods 700 longitudinally assist in stirring and prevent liquid stratification. The bottom ends of multiple vertical stirring rods 700 are connected to a bottom scraper 1300, which adheres to the bottom of the tank to prevent sediment formation.

[0030] The tank body 100 has a base 900 at its bottom, and a motor 1000 is installed at the bottom of the base 900. The motor is connected to an external power supply and controller. The output shaft of the motor 1000 passes through the bottom of the base 900 and is coaxially connected to a copper rotor 1100. The front end of the bottom of the tank body 100 has a discharge pipe 110 with a valve. The discharge pipe 110 is used to control the discharge of fermented milk. Under the push of the scraper plate 1300, a centrifugal force is generated, which pushes the fermented milk toward the discharge pipe 110.

[0031] In this embodiment, a cooling chamber 101 is provided between the inner wall and the outer wall of the tank 100. A spiral heat exchange tube 300 is provided in the cooling chamber 101. The spiral heat exchange tube 300 maintains the low-temperature fermentation environment inside the tank by circulating coolant.

[0032] Specifically, the spiral heat exchange tube 300 has a coolant inlet 310 at its inlet end, which is connected to an external refrigeration unit and inputs the cooling medium. The spiral heat exchange tube 300 has a solution outlet 320 at its outlet end, which outputs coolant to complete the circulation. Both the coolant inlet 310 and the solution outlet 320 pass through the inner wall of the cooling chamber 101 to the outside. The coolant inlet 310 is located below the solution outlet 320. A temperature sensor installed on the inner wall of the tank 100 monitors the milk temperature in real time. The sensor signal is transmitted to the PLC controller. After comparing with the set temperature threshold, the controller adjusts the operating frequency of the compressor of the refrigeration unit and controls the opening of the electric regulating valve connected to the refrigeration unit and the coolant inlet 310 to dynamically balance the cooling efficiency.

[0033] Furthermore, the rotating vertical rod 500 is rotatably connected to the U-shaped fixed plate 400 via a bearing, and the bottom of the permanent magnet rotor 800 is 2-4mm away from the top of the concave body 120. The spacing design ensures the efficiency of magnetic transmission and avoids mechanical wear.

[0034] Furthermore, the base 900 is bolted to the bottom of the tank 100. The base 900 seals the bottom opening of the concave body 120 to prevent dust from entering the concave body 120 and ensure that the surface of the copper rotor 1100 is free of dust.

[0035] Furthermore, the copper rotor 1100 is located inside the concave body 120, and the top of the copper rotor 1100 is 1-3 mm away from the top of the inner wall of the concave body 120.

[0036] Furthermore, the bottom of the scraper plate 1300 is fitted to the bottom of the inner wall of the tank 100, and the fit ensures that residual material is scraped off.

[0037] Furthermore, a pressure relief valve 1200 is provided on the top of the tank cover 200. The pressure relief valve 1200 automatically releases overpressure gas inside the tank to ensure operational safety.

[0038] In this embodiment, the milk storage tank device for fermented milk production is used by injecting fermented milk into the tank 100 through the feeding pipe 210 with a sealed cover. The motor 1000 is started, driving the copper rotor 1100 to rotate. Through non-contact magnetic transmission between the permanent magnet rotor 800 and the copper rotor 1100, the rotating vertical rod 500 rotates around the U-shaped fixed plate 400. The stirring horizontal rod 600 on the outer wall of the rotating vertical rod 500 rotates synchronously with the stirring vertical rod 700, forming a three-dimensional stirring effect. The horizontal stirring horizontal rod 600 improves the uniformity of the milk, while the vertical stirring vertical rod 700 prevents liquid stratification. Simultaneously, a scraper plate connected to the bottom end of the stirring vertical rod 700... The 1300 plate fits against the bottom of the tank 100, scraping off material during rotation to prevent sedimentation. During stirring, the spiral heat exchange tube 300 receives coolant from the external refrigeration equipment through the coolant inlet 310. After circulating through the spiral heat exchange tube 300, the coolant is discharged from the solution outlet 320. The temperature is monitored in real time by a temperature sensor on the inner wall of the tank 100, and the frequency of the refrigeration unit compressor and the opening of the electric regulating valve are dynamically adjusted by a PLC controller to maintain a low-temperature storage environment. When fermented milk needs to be discharged, the valve of the discharge pipe 110 is opened, and the centrifugal force generated by the rotation of the scraper plate 1300 pushes the fermented milk towards the discharge pipe 110 for discharge.
