Abstract
Description
Technical Field
[0001] This utility model relates to the field of cheese production technology, and in particular to a mixing device for raw materials used in cheese production. Background Technology
[0002] Cheese, also known as curd, is a distinctive fermented dairy product. In the cheese production process, mixing equipment is an indispensable key piece of equipment, directly affecting the quality of the mixing of cheese raw materials, and thus the quality of the final cheese product.
[0003] A search revealed a mixing device for cheese production raw materials, with publication number CN216604962U. This device mainly consists of a main body with a discharge port at the bottom for easy discharge of the mixed raw materials. A support rod is fixedly connected to the bottom of the main body for stability. As the threaded rod rotates, it drives the threaded cylinder and the mixing drum to rotate together. The rotation of the mixing drum thoroughly mixes the raw materials within the main body, ensuring proper mixing.
[0004] However, while existing patents have addressed the issues of uneven mixing and raw material adhesion to the inner wall to some extent through the aforementioned design, they still fall short in handling density stratification that may occur during the mixing process. During cheese raw material mixing, density stratification easily occurs due to differences in the density of different ingredients. For example, heavier material particles may gradually sink, while lighter materials may float, resulting in uneven mixing. This density stratification caused by uneven mixing significantly reduces the quality of the raw material mixture, thereby affecting the cheese's taste, texture, and the uniform distribution of its nutrients. Summary of the Invention
[0005] The purpose of this invention is to provide a mixing device for raw materials in cheese production. By using a one-way valve on a movable cover and a fixed cover, the raw materials at the bottom of the equipment shell can be injected into the top of the equipment shell through a circulation pipe for re-mixing, thereby preventing density stratification caused by uneven mixing and solving the problems mentioned in the background art.

[0024] 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.
[0025] This utility model provides a technical solution:
[0026] Please see Figures 1 to 3 A mixing device for raw materials in cheese production includes a housing 1. A mixing component 2 is installed at the top and inside of the housing 1. The mixing component 2 includes a mixing motor 21 fixedly installed at the top of the housing 1. A mixing shaft 22 is fixedly installed at the output end of the mixing motor 21. A mixing grinding disc 27 is fixedly installed at the bottom of the mixing shaft 22. A circulation component 7 is installed at the bottom of the mixing grinding disc 27.
[0027] The circulation assembly 7 includes an eccentric disk 71 fixedly mounted at the bottom of the mixing and grinding disk 27. An eccentric shaft 72 is fixedly mounted at the bottom of the eccentric disk 71. A rotating sleeve 73 is sleeved on the outer side of the eccentric shaft 72. A push column 74 is fixedly mounted on the outer side of the rotating sleeve 73. A movable cover 75 is fixedly mounted at the end of the push column 74. A one-way tube 78 is fixedly mounted on the outer side of the movable cover 75. A fixed cover 76 is fixedly mounted inside the one-way tube 78. A circulation tube 79 is fixedly mounted at the end of the one-way tube 78. The movable cover 75 and the fixed cover 76 are internally fixed. A one-way valve 77 is installed. The one-way valve 77 on the movable cover 75 is open to the one-way pipe 78 (only external raw materials are allowed to enter the pipe), and the one-way valve 77 on the fixed cover 76 is open to the circulation pipe 79 (only raw materials inside the pipe are allowed to enter the circulation pipe 79). The one-way valve 77 adopts a spring-type structure. The output end of the circulation pipe 79 is connected to the upper part of the equipment housing 1. According to the usage requirements, a 45° inclined diffusion nozzle can be provided at the outlet to spray the circulating raw material in the tangential direction, thereby enhancing the mixing effect with the main raw material.
[0028] A mixing fan blade 23 is fixedly installed on the outside of the mixing shaft 22, and a mixing support column 24 is fixedly installed at the lower end of the mixing shaft 22. A mixing brush 25 is fixedly installed on the surface of the mixing support column 24. A mixing and grinding groove 26 is opened inside the lower end of the equipment housing 1. The gap between the mixing and grinding disc 27 and the mixing and grinding groove 26 is set to 0.5-1.5mm. Radially distributed triangular protrusions are provided on the opposite surfaces of the mixing and grinding disc 27 and the mixing and grinding groove 26. The edges of the protrusions are rounded to avoid excessive shearing of the raw materials.
[0029] By adopting the above technical solution, during use, the mixing motor 21 drives the mixing shaft 22 to rotate. The rotation of the mixing shaft 22 drives the mixing blades 23 on the mixing shaft 22 to stir the raw materials. At the same time, the mixing brush 25 sleeved on the mixing support column 24 on the mixing shaft 22 cleans the inner wall of the equipment shell 1. The mixing brush 25 can be made of food-grade silicone bristles to prevent the raw materials for cheese production from sticking to the inside of the equipment shell 1. During the mixing process, the curd particles in the raw materials are broken down by the mixing grinding disc 27 in the mixing grinding tank 26, making the mixing more uniform. During the mixing process, the mixing grinding disc 27 drives the eccentric disc 71 to rotate, and the eccentric disc 71 drives the eccentric shaft 72 to rotate. The rotation of the eccentric shaft 72 drives the... The rotating sleeve 73 moves, which drives the push column 74 to move horizontally, thereby pushing the moving cover 75 to move inside the one-way tube 78. During the movement of the moving cover 75, when the moving cover 75 is close to the fixed cover 76, the distance between the two is compressed, so the raw material inside the one-way tube 78 enters the circulation tube 79 through the one-way valve 77. When the moving cover 75 is away from the fixed cover 76, the distance between the two increases and the internal air pressure decreases, so the production raw material can enter the one-way tube 78 from the one-way valve 77 on the moving cover 75. Through this setting, the cheese production raw material at the bottom of the equipment shell 1 can be reinjected through the circulation tube 79, thereby eliminating density stratification during mixing.
[0030] Specifically, such as Figures 1-2 As shown, a support platform 5 is fixedly installed on the outside of the equipment housing 1. A high-temperature nitrogen assembly 3 is installed on the top of the support platform 5. The high-temperature nitrogen assembly 3 includes a heating shell 32 fixedly installed on the top of the support platform 5. A nitrogen inlet pipe 31 is fixedly installed on the top of the heating shell 32. A heating plate 33 is fixedly installed inside the heating shell 32. A high-temperature nitrogen pipe 34 is fixedly installed between the heating shell 32 and the equipment housing 1.
[0031] A suction assembly 4 is installed at the top of the support platform 5. The suction assembly 4 includes an air pump 42 fixedly installed at the top of the support platform 5. An air suction pipe 41 is fixedly installed between the air pump 42 and the equipment housing 1. The air suction pipe 41 is connected to the center of the top of the equipment housing 1. A stainless steel filter screen is installed at the pipe opening to prevent raw materials from being sucked in. The air pump 42 can be a vortex air pump with a flow rate of 20L / min. An air outlet pipe 43 is fixedly installed at the top of the air pump 42.
[0032] A milk feed pipe 8 and an additive feed pipe 9 are fixedly installed on the outside of the equipment shell 1. A discharge pipe 10 is fixedly installed at the lower end of the equipment shell 1. Valves 6 are installed inside the nitrogen inlet pipe 31, the gas outlet pipe 43, the milk feed pipe 8, and the additive feed pipe 9. The milk feed pipe 8 and the additive feed pipe 9 are connected to the middle of the equipment shell 1, with the pipe openings facing the rotation direction of the mixing fan blades 23, so that the raw materials can directly enter the mixing area. The discharge pipe 10 is located at the center of the bottom end of the equipment shell 1, adopts an inverted cone structure, and a pneumatic ball valve is installed at the bottom to ensure that no raw materials are discharged without residue.
[0033] By adopting the above technical solution, the air pump 42 needs to be turned on. The air pump 42 moves to draw air from inside the equipment shell 1 through the suction pipe 41 and discharge it through the exhaust pipe 43. During this process, the air inside the equipment shell 1 is prevented from affecting the subsequent mixing of raw materials for cheese production. The heating plate 33 inside the heating shell 32 heats the nitrogen entering the heating shell 32 from the nitrogen inlet pipe 31. The heating plate 33 consists of three sets of stainless steel electric heating plates with a power of 1.5kW, which are evenly distributed in a ring. The heating temperature is adjusted by a PID controller. The nitrogen is discharged into the equipment shell 1 through the high-temperature nitrogen pipe 34. Then, the raw materials are injected into the equipment shell 1 through the milk inlet pipe 8 and the additive inlet pipe 9, respectively. After production is completed, the mixed liquid is discharged through the discharge pipe 10. The valve 6 can be used to seal the equipment shell 1 to prevent external factors from causing unnecessary interference to the raw materials inside the equipment shell 1.
[0034] Working Principle: During use, before mixing, the air pump 42 on the support platform 5 draws air from inside the equipment shell 1 through the suction pipe 41 and discharges it through the exhaust pipe 43. The heating plate 33 inside the heating shell 32 heats the nitrogen entering the heating shell 32 from the nitrogen inlet pipe 31 and discharges it into the equipment shell 1 through the high-temperature nitrogen pipe 34. During mixing, the mixing motor 21 on the equipment shell 1 is started, which drives the mixing shaft 22 to rotate. The mixing shaft 22 drives the mixing blades 23 to mix the raw materials. The mixing brush 25 on the mixing support column 24 on the mixing shaft 22 cleans the raw materials on the inner wall of the equipment shell 1 to prevent them from sticking to the inner wall. The coagulated particles in the raw materials are crushed by the mixing grinding disc 27 in the mixing grinding tank 26 to make them evenly mixed. The eccentric shaft 72 on the eccentric disc 71 below the mixing grinding disc 27 drives the rotating sleeve 73 to move, thereby driving the push column 74 and the moving cover. 75 moves horizontally within the one-way pipe 78. When the movable cover 75 approaches the fixed cover 76, due to the action of the one-way valve 77, the raw materials inside the one-way pipe 78 cannot leave the one-way pipe 78 through the movable cover 75, but can only enter the circulation pipe 79 through the one-way valve 77 on the fixed cover 76. When the movable cover 75 moves away from the fixed cover 76, due to the decrease in air pressure inside the one-way pipe 78, the raw materials inside the equipment shell 1 can enter the one-way pipe 78 through the one-way valve 77, while the raw materials inside the circulation pipe 79 cannot enter the one-way pipe 78 through the one-way valve 77 on the fixed cover 76, thus achieving circulation. The raw materials inside the circulation pipe 79 are then injected back into the equipment shell 1 to eliminate density stratification during the mixing process. Raw materials are added into the equipment shell 1 through the milk feed pipe 8 and the additive feed pipe 9, and the mixed raw materials are discharged through the discharge pipe 10. During this process, the valve 6 controls the opening and closing status of each pipe in the equipment.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
