[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a yeast culture device that can make the raw materials in the tank more uniformly stirred. In addition, the device can prevent the raw materials from sticking to the tank wall for a long time during the stirring process and prevent the residue from being completely removed during the cleaning process.

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

[0006] A yeast culture device includes a stirring device, a culture tank, and a cleaning device. The stirring device includes a tank top and a stirring shaft. A sliding frame is fixedly installed on one side of the upper end of the tank top. A sliding groove is opened in the middle of the sliding frame, and a sliding plate is slidably installed inside the sliding groove.

[0007] The stirring device is installed on the upper end face of the culture tank and the cleaning device is installed on the lower end face of the culture tank. The culture tank includes a tank body, and three support legs are fixedly installed on the lower end face of the tank body near the outer periphery. The cleaning device includes a second motor, and the output end of the second motor passes through the lower end of the tank body and is fixedly connected to a cleaning frame. Stirring blocks are fixedly installed on the inner bottom surface of the cleaning frame near the front and rear ends of the inner wall and on both sides of the inner wall.

[0008] Furthermore, a first motor is fixedly installed on the other side of the outer wall of the sliding plate.

[0009] Furthermore, a rotating hole is provided in the middle of the top of the barrel, and the output end of the first motor passes through the rotating hole and is fixedly connected to one end of the stirring shaft.

[0010] Furthermore, an electric telescopic rod is fixedly installed on one side of the upper surface of the barrel and on the side of the sliding frame, and the output end of the electric telescopic rod is fixedly connected to the lower surface of the support block.

[0014] This utility model has the following beneficial effects:

[0015] 1. The present invention proposes a yeast culture device. In common yeast stirring devices, uneven stirring will lead to inconsistent product quality in a batch. This device drives the support block to move vertically up and down through an electric telescopic rod, and then drives the stirring shaft to rotate the stirring blades through the first motor. During the rotation and stirring process, the yeast raw material at the top can be carried to the bottom and the yeast raw material at the bottom can be carried to the top, which can make the stirring more uniform.

[0027] 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.

[0028] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5This utility model provides an embodiment of a yeast culture device, including a stirring device 1, a culture tank 2, and a cleaning device 3. The stirring device 1 includes a tank top 101 and a stirring shaft 107. A sliding frame 102 is fixedly installed on one side of the upper end of the tank top 101. A sliding groove is opened in the middle of the sliding frame 102, and a sliding plate 103 is slidably installed inside the sliding groove. A support block 105 is fixedly installed on one side of the outer wall of the sliding plate 103. Two stirring blades 108 are fixedly installed on the outer wall of the stirring shaft 107. A first motor 106 is fixedly installed on the other side of the outer wall of the sliding plate 103. A rotating hole is opened in the middle of the tank top 101. The output end of the first motor 106 passes through the rotating hole and is fixedly connected to one end of the stirring shaft 107. An electric telescopic rod 104 is fixedly installed on one side of the upper end of the tank top 101 and on one side of the sliding frame 102. The output end of the electric telescopic rod 104 is fixedly connected to the lower end of the support block 105. An inlet and an exhaust pipe are fixedly connected to the front end of the upper end of the tank top 101.

[0029] Specifically, the sliding engagement between the sliding frame 102 and the sliding plate 103 prevents the first motor 106 from rotating due to its own torque, and the sliding frame 102 restricts its movement to vertical up and down. The electric telescopic rod 104 drives the sliding plate 103 to move the first motor 106 up and down to stir the yeast raw materials, making the stirred yeast raw materials more uniform.

[0030] Reference Figure 2 , Figure 6 , Figure 8 The stirring device 1 is installed on the upper end face of the culture tank 2, and the cleaning device 3 is installed on the lower end face of the culture tank 2. The culture tank 2 includes a tank body 201. Three support legs 202 are fixedly installed on the lower end face of the tank body 201 near the outer periphery. A discharge pipe and a drain pipe are fixedly connected to the lower two sides of the outer wall of the tank body 201. The top of the tank 101 is fixedly installed on the upper end of the tank body 201. The stirring shaft 107 is located inside the tank body 201 and rotates and moves vertically up and down.

[0031] Specifically, with the support of the outrigger 202, a second motor 301 can be fixedly placed at the lower end of the barrel 201. Because the height of the barrel 201 is raised, the raw materials or cleaning water inside the barrel 201 can be discharged more effectively through the discharge pipe and drain pipe.

[0032] Reference Figure 3 , Figure 7 , Figure 8 The cleaning device 3 includes a second motor 301. The output end of the second motor 301 passes through the lower end of the barrel 201 and is fixedly connected to a cleaning rack 302. Stirring blocks 303 are fixedly installed on the bottom surface of the cleaning rack 302 near the front and rear ends of the inner wall and on both sides of the inner wall. The second motor 301 is fixedly installed in the middle of the lower end face of the barrel 201. The cleaning rack 302 is rotatably installed inside the barrel 201 near the lower end.

[0033] Specifically, with the assistance of the cleaning rack 302, the raw materials adhering to the inner wall of the barrel 201 can be scraped off and reintroduced into the mixing cycle during the stirring process, which can effectively avoid uneven mixing, and can effectively remove the residue on the inner wall of the barrel 201 when cleaning the inside of the barrel 201.

[0034] Working Principle: During the yeast ingredient mixing process, some yeast ingredients tend to adhere to the inner wall of the container 201. The ingredients adhering to the inner wall of the container 201 cannot participate in the normal mixing cycle, resulting in uneven mixing and affecting product quality consistency. Through the operation of the cleaning device 3, the output end of the second motor 301 drives the cleaning rack 302 to rotate, scraping off the ingredients adhering to the inner wall of the container 201. The cleaning device 3 is constantly running during the mixing process, continuously reintroducing the ingredients adhering to the inner wall of the container 201 into the mixing cycle. If residues are not thoroughly cleaned from the inside of the container 201, bacteria will grow, potentially leading to culture failure. When cleaning the inside of the barrel 201, water is poured into the barrel for cleaning. The cleaning device 3 operates, and the output of the second motor 301 drives the cleaning rack 302 to rotate. The cleaning rack 302 continuously scrapes away residue and moisture from the inner wall of the barrel 201. The stirring device 1 stirs the water, and the stirring blades 108 drive the water flow to rinse the inner wall of the barrel 201. Multiple rinses by the water flow and the scraping by the cleaning rack 302 effectively ensure the cleanliness of the inside of the barrel 201. Uniform stirring should be maintained during the stirring process to ensure the consistency of the batch's product quality. During stirring, the output of the first motor 106 drives the stirring shaft 107 to rotate the stirring blades 108. The electric telescopic rod 104 drives the sliding plate 103 to move the first motor 106 vertically up and down. When the stirring blades 108 rise, they can bring the raw materials at the bottom to the top; when the stirring blades 108 descend, they can bring the raw materials at the top to the bottom. With the assistance of the stirring blocks 303 of the cleaning device 3, the internal stirring can be made uniform. The length of the stirring blade 108 is less than the inner diameter of the cleaning frame 302, and its vertical movement range is limited. During the stirring process, the stirring blade 108, the stirring block 303, and the cleaning frame 302 do not affect each other. The first motor 106, the second motor 301, and the electric telescopic rod 104 are all mature and publicly available technologies. Therefore, their specific structures and working principles will not be described in detail in this paper.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
