[0002] Cream is a yellow or white fatty semi-solid food extracted from cow's or goat's milk. It is a dairy product made from the top layer of raw, unhomogenized milk, which has a high milk fat content. Fermented cream, produced by adding probiotics to sterilized dairy products, has a rich flavor and is widely used in food production.

[0003] During the cream fermentation process, a fermentation tank is required to ferment the cream. For example, a utility model patent with Chinese patent publication number CN210017693U proposes a fermentation tank for cream fermentation. The fermentation tank can add materials into the tank body from a feeding port. After the feeding is completed, the sealing cover is placed on the feeding port by reverse operation.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0019] The present application embodiment discloses a fermentation tank for cream fermentation. Figure 1 and Figure 2 The fermentation tank for cream fermentation may include a tank body 10, a heat conducting portion 20, and a stirring portion 30. The heat conducting portion 20 is mounted inside the tank body 10 and cooperates with the tank body 10 to adjust the temperature environment required for cream fermentation in the tank body 10. The stirring portion 30 is mounted on the top of the tank body 10, with the lower end of the stirring portion 30 extending into the tank body 10 and remaining inside the heat conducting portion 20. The stirring portion 30 is used to stir the raw materials contained in the tank body 10.

[0020] See Figure 3The tank body 10 may include an outer tank body 11, an inner tank body 12, a feeding port 13, an exhaust port 14, a liquid discharge port 15, a material extraction port 16, a top pipe 17, an overflow port 18, and a water inlet 19. The inner tank body 12 is arranged in the inner cavity of the outer tank body 11. The top of the inner tank body 12 is formed with a circle of outer edges protruding outward, and the outer edges are connected and fixed to the inner wall of the outer tank body 11, so that the inner tank body 12 is fixed in the inner cavity of the outer tank body 11. The outer diameter of the inner tank body 12 is smaller than the inner diameter of the outer tank body 11, so that there is a gap between the outer wall of the inner tank body 12 and the inner wall of the outer tank body 11. The lower ends of the feeding port 13 and the exhaust port 14 are both connected to the top of the inner tank body 12, and the upper ends of the feeding port 13 and the exhaust port 14 are both passed through the top of the outer tank body 11. The feeding port 13 and the exhaust port 14 are respectively used to feed raw materials into the inner tank body 12 and to exhaust the inner tank body 12 outward. A one-way valve is installed on the exhaust port 14, ensuring that airflow is directed outward only from the inner tank 12 and preventing outside air from entering. The upper end of the drain port 15 communicates with the bottom of the inner tank 12, and the lower end of the drain port 15 extends below the outer tank 11. This port is used to drain the remaining milk from the inner tank 12 after milk is removed. One end of the material removal port 16 communicates with the side of the inner tank 12, and the other end of the material removal port 16 extends outside the outer tank 11, allowing fermented cream to be removed from the material removal port 16. The overflow port 18 and the water inlet 19 are formed on the outer wall of the outer tank body 11, and the overflow port 18 and the water inlet 19 are connected to the gap between the outer tank body 11 and the inner tank body 12. Cold water can be injected from the water inlet 19 and water can be discharged from the overflow port 18, so that the gap between the outer tank body 11 and the inner tank body 12 is filled with a heat-conducting medium.

[0021] See Figure 4 The heat-conducting part 20 includes a spiral tube 21 and two sections of extension tubes 22. The spiral tube 21 can be made of a heat-conducting metal material to form a spiral metal tube that can conduct heat, and the extension tube 22 can be made of a heat-insulating material to form a straight tube. The spiral tube 21 is arranged in the inner cavity of the inner tank body 12, and both ends of the spiral tube 21 are respectively connected and fixed with a section of extension tube 22, and the two sections of extension tube 22 pass through to the outside of the outer tank body 11. The extension tube 22 is made of heat-insulating material to prevent the heat-conducting medium between the outer tank body 11 and the inner tank body 12 from being directly heated by the heat-conducting part 20. An electric heating wire is installed in the spiral tube 21, and a wire connected to the electric heating wire is passed through the extension tube 22. The electric heating wire can be used to increase the temperature after the wire is connected to an external power supply.

[0022] In this embodiment, the fermentation temperature can be controlled by controlling the heating of the heat conducting portion 20 and cooling the space between the outer tank 11 and the inner tank 12 by injecting a heat conducting medium such as cold water. In addition, a temperature sensor probe can be inserted into the inner tank 12 to monitor the internal temperature.

[0023] See Figure 5 The stirring portion 30 includes a motor 31, a stirring shaft 32 and a plurality of stirring blades 33. The motor 31 is mounted on the top of the top tube 17, the upper end of the stirring shaft 32 is connected to the output end of the motor 31, and the stirring shaft 32 and the plurality of stirring blades 33 are all extended into the inner tank body 12. The plurality of stirring blades 33 are formed on the outer wall of the stirring shaft 32 in an axial and radial array along the stirring shaft 32, and there is a gap between the end of the stirring blade 33 away from the central axis of the stirring shaft 32 and each spiral area of ​​the spiral tube 21, so that the motor 31 can avoid collision and interference with the spiral tube 21 when driving the stirring shaft 32 and the stirring blade 33 to rotate, and the stirring of the stirring shaft 32 and the stirring blade 33 during rotation can be utilized to mix the raw materials evenly, and the milk part and the fat part as the fermented cream in the raw materials can also be separated into layers. Each stirring blade 33 may be formed with a plurality of holes 34 penetrating the stirring blade 33 , so that during the stirring process, the raw materials can pass through the holes 34 at the stirring blade 33 , and the raw materials can be better mixed and homogenized by utilizing the particle collision, turbulence and shear force in the raw materials at the stirring blade 33 during stirring.

[0024] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
