Description

Technical Field

[0001] This utility model relates to the field of liquor production technology, and in particular to a grain mash cooling device. Background Technology

[0002] In the process of brewing baijiu, temperature control of grain mash is crucial. High-temperature stacking of grain mash is an important brewing process for baijiu with aromas such as soy sauce and sesame. The stacking process can capture and enrich microorganisms in the brewing environment, forming a unique and rich microbial community, which in turn produces a variety of enzymes and flavor precursors. The high-temperature stacking process can form and accumulate special aroma components through Maillard reaction or microbial metabolism, thus forming the aroma characteristics of "soy sauce" and "sesame" in the liquor. Depending on the process requirements such as different stacking temperatures and times, the stacked grain mash needs to be turned, broken up, and cooled.

[0003] The prior art disclosure number CN222064457U discloses a device for turning, dispersing, and cooling high-temperature stacked grain mash, including: a lifting frame, with casters fixedly installed at the bottom of the lifting frame, a cooling chamber fixedly connected to the top of the lifting frame, a sealing plate installed on the top of the cooling chamber, multiple fans fixedly installed inside the cooling chamber, a discharge port fixedly connected to one side of the cooling chamber, and a support frame fixedly connected to one side of the cooling chamber. After the lifting frame is moved to a suitable position by the casters, the device performs operations such as turning, cooling, and dispersing the high-temperature stacked grain mash by means of a stirring motor, a stirring component, a conveying motor, a conveying roller, a chain plate, and fans. However, during the fan blowing process, some grain mash and Daqu powder are easily scattered, which not only affects the cleanliness of the site and pollutes the environment, but also wastes raw materials and increases production costs.

[0004] Therefore, there is an urgent need for a grain mash cooling device that can ensure uniform cooling of the grain mash and avoid waste of raw materials. Utility Model Content

[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. 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.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] The specific implementation method is as follows: like Figures 1-4 As shown; This utility model discloses a grain mash cooling device, including a conveying component, a supporting component and a cooling component. The conveying component includes a conveyor belt 5, a conveying motor 6, a conveying shaft 7, a conveying roller 8, a rotating shaft 9 and a rotating roller 10. The conveying roller 8 is fixedly connected to the conveying shaft 7, and the rotating roller 10 is fixedly connected to the rotating shaft 9. The conveyor belt 5 is wound around the conveying roller 8 and the rotating roller 10. Along the conveying direction, a material equalization component and a plurality of turning components are arranged sequentially above the conveyor belt 5. The conveyor motor 6 is fixed to one end of the support assembly. The output end of the conveyor motor 6 is fixedly connected to one end of the conveyor shaft 7. The other end of the conveyor shaft 7 passes through the support assembly. The conveyor shaft 7 is rotatably connected to the support assembly. Both ends of the rotating shaft 9 are rotatably connected to the support assembly. The material distribution assembly includes a support frame and a fixing block 14. The support frame is fixed to one end of the support assembly near the conveyor roller 8. The top of the fixing block 14 has a fixing groove 15. The top of the support frame passes through the fixing groove 15. The support frame is fixedly connected to the fixing block 14. There is a gap 16 between the bottom of the fixing block 14 and the conveyor belt 5. The cooling component includes a cooling pipe 20, which is coiled and fixed to the support component in a serpentine manner.

[0021] This invention uses a conveyor motor 6 to drive a conveyor shaft 7, which in turn drives a conveyor roller 8 to rotate, and a conveyor belt 5 to rotate, thus achieving stable movement of the grain mash. Upon reaching the conveyor belt 5, the grain mash first passes through the gap 16 between the fixing block 14 and the conveyor belt 5, scraping the mash into a thin, uniform layer. This prevents uneven thickness from affecting the cooling effect. Then, multiple turning components turn the thin layer of mash, facilitating downward contact of the upper layer with the conveyor belt 5 and closer proximity to the cooling pipe 20 for easier cooling and uniform cooling of the mash. The turning process also disperses the mash, making the temperature distribution more even. By coiling the cooling pipe 20 in a serpentine pattern around the support components, the cooling area is increased, achieving efficient cooling and improving cooling efficiency.

[0022] In this embodiment, to prevent the mash from accumulating at the fixed block 14, the length of the conveyor belt 5 in front of the fixed block 14 is increased to control the amount of mash falling.

[0023] In this embodiment, the support assembly includes support legs 1 and support plate 2. Support legs 1 are fixed at the four corners of the bottom end of the support plate 2. A first baffle 3 and a second baffle 4 are provided on both sides of the support plate 2, and the support plate 2 passes through the first baffle 3 and the second baffle 4. The support plate 2 is located in the middle of the conveyor belt 5. The conveyor motor 6 is fixed at one end outside the first baffle 3. The other end of the conveyor shaft 7 passes through the first baffle 3 and is rotatably connected to the second baffle 4. The conveyor shaft 7 is rotatably connected to the first baffle 3. The two ends of the rotating shaft 9 are rotatably connected to the other ends of the first baffle 3 and the second baffle 4, respectively.

[0024] In this embodiment, a first fixing plate 13 and a plurality of second fixing plates 23 are welded to the outside of the first baffle 3, the conveying motor 6 is placed at the top of the first fixing plate 13, and the flipping motor 17 is placed at the top of the second fixing plate 23.

[0025] The support leg 1 of this utility model provides a stable support foundation for the entire device, ensuring that the device is not easily shaken during operation. The first baffle 3 and the second baffle 4 on both sides of the support plate 2 provide stable installation support for the conveying shaft 7 and the rotating shaft 9. The conveying shaft 7 and the rotating shaft 9 are rotatably connected to the baffles, ensuring the smooth rotation of the conveying roller 8 and the rotating roller 10, thereby enabling the conveyor belt 5 to operate stably and providing a guarantee for the stable conveying of grain mash.

[0026] In this embodiment, the support frame includes vertical support rods 11 and horizontal support rods 12. The bottom ends of the two vertical support rods 11 are fixedly connected to the top end of the support plate 2. A horizontal support rod 12 is fixed between the two vertical support rods 11. The horizontal support rod 12 passes through the fixing groove 15 and is welded to the fixing block 14. The two sides of the fixing block 14 are in contact with the first baffle 3 and the second baffle 4, respectively.

[0027] The vertical support rod 11 and the horizontal support rod 12 of this utility model realize the fixed support of the fixed block 14; the two sides of the fixed block 14 are in contact with the first baffle 3 and the second baffle 4 respectively. The baffles form a horizontal limit on the fixed block 14, preventing the fixed block 14 from shifting laterally when the grain mash is impacted or the device vibrates, and at the same time preventing the grain mash from moving backward from both sides of the fixed block 14.

[0028] In this embodiment, the vertical support rod 11 includes a first vertical rod and a second vertical rod. The bottom of the first vertical rod has a first through hole, and the top of the second vertical rod has multiple second through holes. The bottom of the first vertical rod is inserted into the top of the second vertical rod. After selecting the gap height between the fixing block 14 and the conveyor belt 5, the bolt is passed from one side of the first vertical rod through the first through hole and the second through hole to the other side of the first vertical rod. The nut is tightened with the bolt on the other side of the first vertical rod to fix the first vertical rod and the second vertical rod.

[0029] In this embodiment, the conveyor belt 5 is made of metal; specifically, 304 stainless steel is selected. Metal has good thermal conductivity, which can effectively realize the hot and cold exchange between the grain mash and the liquid in the cooling pipe 20, thereby achieving rapid cooling of the grain mash and improving the cooling rate. The conveyor belt is a continuous strip structure composed of multiple steel plates.

[0030] In this embodiment, the height of the gap 16 is 2cm; setting the height of 2cm effectively limits the height of the mash, so that the pile of mash becomes a mash layer of uniform thickness for backward transport.

[0031] In this embodiment, the flipping assembly includes a flipping motor 17, a flipping shaft 18, and flipping blades 19. The flipping motor 17 is fixed to the outside of the first baffle 3. The output end of the flipping motor 17 is fixedly connected to one end of the flipping shaft 18. The other end of the flipping shaft 18 passes through the first baffle 3 and is rotatably connected to the second baffle 4. The flipping shaft 18 is rotatably connected to the first baffle 3. A plurality of flipping blades 19 are evenly distributed on the flipping shaft 18.

[0032] The flipping blade 19 of this invention rotates synchronously with the flipping shaft 18, which fully flips the grain mash on the conveyor belt 5, so that the low-temperature grain mash that was originally at the bottom and has been cooled by contact with the conveyor belt 5 is flipped to the upper layer, and the grain mash that has not been cooled enough in the upper layer is moved to the lower layer to contact the conveyor belt 5, which greatly improves the uniformity of contact between the grain mash and the cooling environment.

[0033] In this embodiment, the flipping blade 19 is square in shape, and the two sides of the flipping blade 19 are in contact with the first baffle 3 and the second baffle 4 respectively. The side of the flipping blade 19 away from the flipping shaft 18 is in contact with the top of the conveyor belt 5.

[0034] Compared to ordinary flat blades, the square-shaped blades of this invention have a larger contact area for turning and can more comprehensively turn the grain mash when rotating, which can more effectively break up local agglomeration of the grain mash and allow the grain mash to be fully mixed under the pushing and stirring of the blades.

[0035] In this embodiment, one end of the cooling pipe 20 is an inlet 21 and the other end is an outlet 22. Both the inlet 21 and the outlet 22 are connected to an external water source. The cooling pipe 20 is coiled and fixed to the support plate 2. The cooling pipe 20 is a hollow glass tube. The external water source is a water tank. A compression refrigeration unit is installed in the water tank. Its evaporator is fixed to the inner wall of the water tank through a heat-conducting bracket. The condenser and compressor are installed outside the water tank. Heat exchange is achieved through the circulation of refrigerant to cool the water in the water tank. When the water is pumped from the inlet 21 into the cooling pipe 20 and then out of the outlet 22 back into the water tank, the flowing and circulating water can continuously carry away heat.

[0036] In practical use, the grain mash cooling device of this utility model starts the conveyor motor 6, which drives the conveyor roller 8 to rotate, and drives the conveyor belt 5 to stably convey the grain mash under the limit of the first baffle 3 and the second baffle 4. First, the grain mash is placed on the conveyor belt 5 from the end near the conveyor motor 6. After passing through the gap 16 between the fixing block 14 and the conveyor belt 5, it becomes a uniform thin layer. Then it enters the turning area. The turning motor 17 drives the square turning blades 19 to rotate, turning the grain mash. The low-temperature grain mash that was originally at the bottom and has been cooled by contact with the conveyor belt 5 is turned to the upper layer. The grain mash that has not been sufficiently cooled in the upper layer moves to the lower layer to contact the conveyor belt 5. At the same time, the serpentine cooling pipe 20 continuously cools through the external water source. The metal conveyor belt 5 conducts the low temperature to the grain mash, and efficient and uniform cooling is completed in the continuous movement of the grain mash.
