Description

Technical Field

[0001] This utility model relates to the technical field of dairy processing equipment, and in particular to a material storage tank for a milk plate pasteurizer. Background Technology

[0002] In the dairy processing industry, pasteurization is a crucial process step to ensure the quality and safety of milk. After pasteurization, milk needs to be temporarily stored in material storage tanks to provide a stable supply for subsequent filling or further processing. Traditional milk material storage tank designs typically include an injection pump and a discharge pump, responsible for the injection and discharge of milk respectively.

[0003] However, during the operation of traditional storage tanks, the injection pump directly vents air from the tank to the outside environment when filling it with milk; conversely, when the discharge pump empties the milk, negative pressure forms inside the tank due to the reduced milk volume, causing outside air to be drawn into the tank. During this process, outside air may carry microorganisms, dust, and other contaminants, directly contacting the pasteurized milk inside the tank, thus increasing the risk of secondary contamination and seriously affecting product quality and safety. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a material storage tank for a milk plate pasteurizer. During use, this storage tank ensures that the internal air is relatively clean, preventing the introduction of external air. In addition, the use of a stirring mechanism can promote the emulsification and dispersion of components such as fat globules in the material, improve product stability, and prevent stratification or sedimentation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A material storage tank for a milk plate pasteurizer includes a tank body with a connecting pipe at the top. A liquid pump is installed on the right side of the tank body, and the inlet end of the liquid pump extends to the bottom inner space of the tank body. A stirring mechanism includes a drive motor mounted at the upper end of the tank body, the output shaft of which extends into the tank body and is fixedly connected to a rotating shaft. Multiple stirring rods are fixedly connected to the outer side of the rotating shaft. A gas storage mechanism cooperates with the tank body to ensure the cleanliness of the gas inside the tank.

[0007] Preferably, a ring-shaped ultraviolet lamp is installed on the inner top of the tank.

[0008] Preferably, the gas storage mechanism includes a connecting strip fixedly connected to the rear side of the tank, a gas storage cylinder fixedly connected to the rear side of the connecting strip, a piston plate that can slide up and down inside the gas storage cylinder, and the inner bottom of the gas storage cylinder communicating with the top space of the tank through a connecting pipe.

[0009] Preferably, the inner top space of the air storage cylinder is provided with an opening.

[0010] Preferably, the volume of the gas storage cylinder is greater than the volume of the tank.

[0011] Preferably, both the rotating shaft and the stirring rod are made of plastic.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] When disinfection of the air inside the tank is required, the ring-shaped ultraviolet lamp is activated. The ultraviolet light it generates irradiates the air inside the tank, destroying the nucleic acid structure of microorganisms and achieving disinfection. After a certain period of time, it is turned off. After disinfection, sterilized milk is supplied into the tank through a connecting pipe. When discharging, the liquid pump is activated to draw the milk from the bottom of the tank and transport it to subsequent equipment. During the supply and discharge process, the gas storage mechanism maintains stable air pressure inside the tank through the movement of the piston plate in the gas accumulator, preventing the introduction of external air. At the same time, the stirring rod of the stirring mechanism agitates the milk, promoting the emulsification and dispersion of components such as fat globules, improving the stability and quality of the milk.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3A material storage tank for a milk plate pasteurizer includes a tank body 1. The top space of the tank body 1 is connected to a connecting pipe 3. A liquid pump 7 is installed on the right side of the tank body 1. The inlet end of the liquid pump 7 extends to the inner bottom space of the tank body 1. A ring-shaped ultraviolet lamp 11 is installed on the inner top of the tank body 1. The ring-shaped ultraviolet lamp 11 can be used to disinfect the air. One end of the connecting pipe 3 extends to the inner bottom of the tank body 1, and the other end is connected to the external pump body for inputting pasteurized milk. Furthermore, both the outlet end of the pump body and the inlet end of the liquid pump 7 are equipped with check valves to prevent backflow.

[0020] The device also includes a stirring mechanism, which includes a drive motor 2 installed at the upper end of the tank 1. The output shaft of the drive motor 2 extends into the tank 1. A rotary sealing gasket is installed at the point where the output shaft of the drive motor 2 passes through the tank 1 to ensure the sealing of the rotational connection. A rotating shaft 9 is fixedly connected to the shaft. Multiple stirring rods 10 are fixedly connected to the outside of the rotating shaft 9. Both the rotating shaft 9 and the stirring rods 10 are made of plastic. Food-grade plastic is used here to ensure safety. Stirring can promote the emulsification and dispersion of components such as fat globules in the material, improve product stability, and prevent stratification or sedimentation.

[0021] It also includes a gas storage mechanism, which works in conjunction with the tank 1 to ensure the cleanliness of the gas inside the tank 1. The gas storage mechanism includes a connecting strip 12 fixedly connected to the rear side of the tank 1. A gas storage cylinder 4 is fixedly connected to the rear side of the connecting strip 12. The volume of the gas storage cylinder 4 is larger than the volume of the tank 1. A piston plate 8 that can slide up and down is provided inside the gas storage cylinder 4. The bottom of the gas storage cylinder 4 is connected to the top space of the tank 1 through a connecting pipe 6. An opening 5 is provided in the top space of the gas storage cylinder 4. The connecting pipe 6 uses a tank with a small diameter, so there is less residual gas inside and it will not affect the whole.

[0022] In this invention, when it is necessary to disinfect the air inside the tank 1, the ring-shaped ultraviolet lamp 11 is first activated. The ring-shaped ultraviolet lamp 11 begins to emit light, and the ultraviolet rays it generates irradiate the internal space of the tank 1. The ultraviolet disinfection process is as follows: the ultraviolet rays irradiate the air inside the tank 1, destroying the nucleic acid structure of microorganisms in the air, causing them to lose their ability to reproduce, thereby achieving the purpose of air disinfection. After a certain period of ultraviolet irradiation, the required disinfection standard is reached, and the ring-shaped ultraviolet lamp 11 is turned off, ending the air disinfection process inside the tank 1.

[0023] After the internal air sterilization of tank 1 is completed, the sterilized milk is prepared to be supplied into tank 1. Ensure that the connecting pipe 3 is correctly connected to the external pump and that the pump is in a working state. Start the external pump, and it will begin working, delivering the sterilized milk into tank 1 through the connecting pipe 3. The milk first enters the bottom space of tank 1. As milk is continuously supplied, the liquid level in tank 1 gradually rises. When it is necessary to discharge milk from tank 1, ensure that the liquid pump 7 is in a working state and that its outlet is correctly connected to subsequent processing equipment or storage containers. Start the liquid pump 7, and it will begin working, drawing milk from the bottom of tank 1 through its inlet and discharging it from its outlet into subsequent processing equipment or storage containers.

[0024] During the milk supply and discharge process, the gas volume inside tank 1 changes. When milk is supplied, the gas inside tank 1 is compressed, and the gas pressure increases; when milk is discharged, the gas volume inside tank 1 increases, and the gas pressure decreases. At this time, the gas storage mechanism comes into play. When the gas pressure inside tank 1 increases, the gas enters the bottom space of the gas storage cylinder 4 through the connecting pipe 6, pushing the piston plate 8 upward to store the excess gas. When the gas pressure inside tank 1 decreases, the piston plate 8 moves downward under the action of the gas pressure inside the gas storage cylinder 4 and its own gravity, pushing the gas in the bottom space of the gas storage cylinder 4 back into tank 1 through the connecting pipe 6, maintaining the relative stability of the gas pressure inside tank 1. Throughout the process, no external air is introduced, avoiding the influence caused by external gas supply.

[0025] After milk is fed into tank 1, in order to promote the emulsification and dispersion of components such as fat globules in the material, improve product stability, and prevent stratification or sedimentation, the stirring mechanism is activated. The output shaft of the drive motor 2 drives the rotating shaft 9 to rotate. Since the rotating shaft 9 is fixedly connected to the stirring rod 10, the stirring rod 10 also rotates with the rotating shaft 9. The stirring rod 10 continuously stirs the milk in tank 1, so that the components such as fat globules in the milk are evenly dispersed, making it less likely to stratify, thereby improving the stability and quality of the milk.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
