Description

Technical Field

[0001] This utility model relates to the field of yeast cooling technology, specifically to a yeast cooling machine. Background Technology

[0002] In the traditional process of brewing baijiu, temperature control of the starter culture is a very important step. During the preparation of the starter culture, a lot of heat is generated during fermentation. If the heat is not dissipated in time, the activity of microorganisms will decrease or even die, which will affect the quality of the starter culture.

[0003] In existing technologies, the temperature of yeast is reduced by manual spreading or by a cooling machine. Traditional manual spreading is not only inefficient but also requires a lot of manpower. Existing cooling machines can only cool the yeast once. After the yeast passes through, it may not meet the actual cooling requirements. It is necessary to manually guide the yeast back to the starting end of the equipment to pass through again for cooling. The operation is complicated and requires a lot of manpower.

[0006] A cooling machine for yeast starter includes a mounting frame with an inverted U-shaped vertical cross-section. A conveying assembly is connected to the mounting frame for conveying the yeast starter. The machine also includes a cooling mechanism and a circulation mechanism, both of which are connected to the mounting frame.

[0007] The cooling mechanism includes a cooling fan and a stirring assembly. Several cooling fans are installed on the upper end of the mounting frame to blow air and cool the yeast on the conveyor belt.

[0009] Furthermore, the conveying assembly includes an active conveying roller and a driven conveying roller. Both the active and driven conveying rollers are rotatably mounted in the mounting frame via a rotating shaft. A first motor is fixed to the outside of the mounting frame to drive the rotating transmission roller to rotate. A conveyor belt is fitted onto the active and driven conveying rollers and drives the conveyor belt to rotate within the mounting frame.

[0011] Furthermore, the number of the stirring components corresponds one-to-one with the refrigeration fan. Each stirring component includes a second motor and a stirring frame. The second motor is fixed to the outside of the mounting frame, and a first connecting shaft is fixed to the output end of the second motor. The first connecting shaft is rotatably connected to the mounting frame, and several stirring frames are fixed to the first connecting shaft. The stirring frame is configured as a T-shaped mechanism.

[0012] Furthermore, the lower end of the refrigeration fan is fixedly connected to the upper end of the mounting bracket via a support frame, the outer end of the refrigeration fan is provided with an air inlet, and the lower end of the refrigeration fan is provided with an air outlet.

[0025] Example 1:

[0026] like Figure 1-5As shown, a cooling machine for yeast starter includes a mounting frame 1 with an inverted U-shaped vertical cross-section. A conveying assembly 2 is connected to the mounting frame 1 for conveying the yeast starter. The conveying assembly 2 includes a driving conveyor roller 202 and a driven conveyor roller 203, both rotatably mounted in the mounting frame 1 via a rotating shaft. A first motor 201 is fixed to the outside of the mounting frame 1 to drive the rotating transmission rollers. A conveyor belt 204 is fitted onto the driving and driven conveyor rollers 202 and 203, driving the conveyor belt 204 to rotate within the mounting frame 1. A horizontally positioned support plate is fixed within the mounting frame 1. 101, the upper side of the inner wall of the conveyor belt 204 is rotatably attached to the upper end of the support plate 101, and the inner end of the mounting frame 1 is fixedly connected to the guide member 102. One side of the guide member 102 is set as a curved surface 103, and one end of the conveyor belt 204 is rotatably attached to the curved surface 103 of the guide member 102. It also includes a cooling mechanism 3 and a circulation mechanism 4. The cooling mechanism 3 and the circulation mechanism 4 are both connected to the mounting frame 1. The first motor 201 drives the transmission belt to rotate, thereby conveying the yeast to move in the mounting frame 1 and being cooled by the cooling mechanism 3. The circulation mechanism 4 can make the yeast circulate back to the conveyor belt 204 for conveying and cooling. Thus, the yeast can be cooled multiple times as needed.

[0027] Example 2:

[0028] like Figure 2-4 As shown, the cooling mechanism 3 includes a cooling fan 301 and a stirring assembly. Several cooling fans 301 are mounted on the upper end of the mounting frame 1 to blow air and cool the yeast on the conveyor belt 204. Several stirring assemblies are sequentially mounted on the lower end of the cooling fans 301 in the mounting frame 1 to stir the yeast on the conveyor belt 204. The number of stirring assemblies corresponds one-to-one with the number of cooling fans 301. Each stirring assembly includes a second motor 305 and a stirring frame 307. The second motor 305 is fixed to the outside of the mounting frame 1, and a first connecting shaft 306 is fixed to the output end of the second motor 305. The connecting shaft 306 is rotatably connected to the mounting frame 1. Several stirring frames 307 are fixedly connected to the first connecting shaft 306. The stirring frames 307 are configured as a T-shaped structure. The lower end of the refrigeration fan 301 is fixedly connected to the upper end of the mounting frame 1 through the support frame 302. The outer end of the refrigeration fan 301 is provided with an air inlet 304 and the lower end of the refrigeration fan 301 is provided with an air outlet 303. When the refrigeration fan 301 blows and cools the conveyed yeast, the stirring frames 307 are driven by the second motor 305 to stir the conveyed yeast to prevent it from clumping. At the same time, the yeast is dispersed to improve the cooling effect.

[0029] Example 3:

[0030] like Figure 4 , 5As shown, the circulation mechanism 4 includes a return box 401 and a circulation box 405. The circulation box 405 is installed at the front end of the mounting frame 1, and the return box 401 is installed at the end of the mounting frame 1. The return box 401 and the circulation box 405 are connected by a return hopper 404 installed with bolts. The return hopper 404 can be disassembled by bolts. The lower end of the circulation box 405 is supported by a support pad, and the lower end of the return hopper 404 is supported by a support leg. 5 is connected to a circulating conveyor assembly for guiding the yeast returned to the circulating box 405 back onto the conveyor belt 204. The return box 401 has a first inlet 402 and a first outlet 403 on one side. The first inlet 402 is connected to the end of the mounting frame 1. The other side of the guide member 102 is a slope 104 extending to the first inlet 402. The return hopper 404 is inclined and its upper end is open. The upper end of the hopper 404 is connected to the first discharge port 403. A second inlet 406 is provided at the lower end of one side of the circulation box 405. The other end of the return hopper 404 is connected to the second inlet 406. The circulation conveying assembly includes a third motor 409 fixedly connected to the upper end of the circulation box 405. A second connecting shaft 410 is fixedly connected to the output end of the third motor 409. The second connecting shaft 410 is rotatably connected inside the circulation box 405, and a component is fixedly connected to the outer periphery of the second connecting shaft 410 within the circulation box. The spiral conveyor plate 411 rotates inside the 405. The upper end of one side of the circulation box 405 is provided with an inclined second discharge port 407. An inclined plate 408 extending downward along the second discharge port 407 is fixed to the outside of the circulation box 405. The inclined plate 408 extends into the upper end of the conveyor belt 204 in the mounting frame 1. After the yeast passes through the return box 401 and the return hopper 404, it enters the circulation box 405. The circulation conveyor assembly guides the yeast back onto the conveyor belt 204 for conveying and cooling.

[0031] In use, the yeast is manually placed on the conveyor belt 204. A first motor 201 drives the active conveyor roller 202 to rotate via a rotating shaft, which in turn drives the conveyor belt 204 to transport the yeast. Simultaneously, a driven conveyor roller 203 supports the rotation of the conveyor belt 204. The yeast moves with the conveyor belt 204. The air outlet 303 at the lower end of the cooling fan 301 blows airflow onto the moving yeast to cool it. At the same time, the stirring assembly at the lower end of the cooling fan 301 uses the output end of a second motor 305 to drive the first connecting shaft 306 to rotate, which in turn drives the stirring frame 307 to stir and disperse the yeast, preventing clumping and improving the cooling effect. After the yeast moves to the guide component via the conveyor belt 204, the end of the curved surface 103 on one side of the guide component 102 scrapes against the conveyor belt 204 to prevent the yeast from adhering to it. Then, the yeast is guided by the guide component 102... 02 The other side of the inclined surface 104 slides down to the first feed port 402 and enters the return box 401. Then it enters the return hopper 404 through the first discharge port 403. The yeast enters the circulation box 405 through the second feed port 406 along the inclined return hopper 404. If necessary, the yeast can be manually loosened to prevent it from accumulating on the return hopper 404. After the yeast enters the circulation box 405, the output end of the third motor 409 drives the second connecting shaft 410 to rotate, which in turn drives the spiral conveyor plate 411 to rotate against the inner wall of the circulation box 405, thus moving the yeast into the box until it moves to the second discharge port 407. After moving along the inclined second discharge port 407, the yeast is guided again to the conveyor belt 204 through the inclined plate 408 outside the circulation box 405 for conveying and cooling, thus realizing multiple cooling of the yeast.

[0032] It is worth noting that after the yeast has completed the cooling process, the return hopper 404 is disassembled using bolts, and the cooled yeast is then collected through the first discharge port 403 using a collection container.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
