Description

Technical Field

[0001] The utility model relates to the technical field of grain moistening equipment, in particular to a grain moistening hopper used for brewing wine. Background Art

[0002] In the liquor production process, grain moistening is also called material moistening, which refers to the process of moistening the raw materials for brewing before cooking, so that the raw materials can evenly absorb a certain amount of water. The traditional Daqu sauce-flavor liquor production process requires that the sorghum must be moistened after it is crushed in a certain proportion and before it is steamed. After the moderately crushed sorghum is moistened, its starch granules absorb the right amount of water, and the sorghum granules swell, laying the foundation for the subsequent steaming and gelatinization. Moistening the grain is to add a certain proportion of hot water to the grain, stir it evenly, and then pour it into the moistening hopper and let it stand for a period of time to allow the grain to fully absorb water.

[0003] In order to further understand the grain moistening hopper in the prior art, after searching, in the prior art, Chinese patent CN216946922U discloses a grain moistening device, including a grain moistening hopper, a temperature detection device and a ventilation component; the grain moistening hopper is used to hold grain; the temperature detection device is arranged in the grain moistening hopper, and the temperature detection device is used to detect the temperature of the grain in the grain moistening hopper; the ventilation component includes a first air port and a second air port, a plurality of first air ports are provided, the plurality of first air ports are respectively connected to the second air port, the plurality of first air ports are arranged in the grain moistening hopper, and the second air port is connected to the atmospheric environment outside the grain moistening hopper.

[0004] After analysis, it is found that the above application realizes ventilation and heat dissipation of grain by setting an air pipe in the middle of the grain moistening hopper. The air pipe is relatively small and the contact area between the air pipe and the grain is small, so there is a problem of low ventilation efficiency; and when pouring grain, grain is easily piled up on the top of the air pipe; in addition, the application does not have a water seepage chamber, and cannot store excess grain moistening water filtered out of the grain, causing the grain to become sour and deteriorate when soaked in the grain moistening water, affecting the quality of the subsequent wine.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The following is combined with Figures 1 to 4 The utility model is further described.

[0028] Example

[0029] In order to solve the technical problems existing in the background technology, the utility model provides a grain moistening hopper.

[0030] The specific technical solution includes a frame 1 and a bucket body 2 arranged on the frame 1, a breathable water filter assembly 3 is arranged in the bucket body 2, and the breathable water filter assembly 3 divides the inner cavity of the bucket body 2 into two, the frame 1 plays a supporting role, the bucket body 2 is used to hold grain, and the breathable water filter assembly 3 is used to ventilate the grain and filter the water in the grain in the bucket body. Among them, the top of the bucket body 2 is an open structure, and the bottom of the bucket body 2 is a closed structure. In order to facilitate the lifting of the bucket body 2, a lifting ear 5 is arranged on the side of the bucket body 2. In order to enhance the rigidity and strength of the bucket body 2, a plurality of ribs 6 are arranged on the side of the bucket body 2.

[0031] In order to solve the problems of low ventilation efficiency and space waste in the prior art grain moistening hopper in the background technology, the present application makes the following improvements to the breathable and water-filtering assembly 3: the breathable and water-filtering assembly 3 includes two partitions 301 arranged vertically at a certain distance, a top plate 302 is provided on the top of the partition 301, the top of the partition 301 is arranged in the middle and upper part of the inner cavity of the hopper body 2, the bottom of the partition 301 is connected to the bottom of the hopper body 2, and a plurality of air holes 303 for ventilation and filtering water in the grain in the hopper body are provided on the partition 301; the two partitions 301 pass through the hopper body 2, and an air permeable cavity 304 connected to the outside is formed between the two partitions 301, and the air permeable cavity 304 is arranged in the middle part of the hopper body 2.

[0032] From the above structure, it can be seen that, firstly, the water filter hole of the existing grain moistening hopper is set at the bottom of the grain moistening hopper, so the water filter hole has to bear the weight of all the grain, which leads to more pressure of the grain on the water filter plate, and the problem of clogging of the water filter hole will occur; while the improved water filter hole of the present application is set on the partition, and the partition is set vertically, so the partition of the present application only needs to bear a smaller horizontal pressure from the grain, so the water filter hole is not easy to be blocked. Secondly, the ventilation method of the existing grain moistening hopper is through two stacked columnar air vents arranged in the hopper body. On the one hand, the contact area between the air vent and the grain is small, and the ventilation efficiency is low; on the other hand, when dumping the grain, the grain will accumulate above the air vent, causing the problem of incomplete dumping. However, the present application is ventilated through the air vents set on the partition, and the contact area between the partition and the grain is large, which improves the ventilation efficiency and avoids the technical problem of material accumulation. Finally, it can be seen that the ventilation and water filtration of the existing grain moistening hopper are achieved by setting two components separately, and the structure is complicated. In contrast, the cleverness of the present application lies in that the ventilation and water filtration functions of the present application are integrated into one component, namely, the ventilation and water filtration component. In comparison, the design of the present application is more clever, and the structure is simpler and more reliable.

[0033] To avoid accumulation of material on the top of the air-permeable water-filtering assembly 3, the present application designs the top plate 302 to be conical, and the width of the top plate 302 gradually increases from top to bottom. To facilitate processing and increase the area of ​​the air-permeable hole, the present application designs the air-permeable hole 303 to be a long hole, and the width of the air-permeable hole 303 is smaller than the diameter of the grain.

[0034] In order to solve the technical problem in the prior art that the grain moistening hopper cannot discharge the excess grain moistening water in time, the present application also makes the following improvements: the present application provides a water holding chamber 305 connected to the air permeable chamber 304 on the frame 1 below the partition 301, and a check valve 306 for drainage is provided at the bottom of the water holding chamber 305.

[0035] First, although the prior art grain moistening hopper is provided with a drain port at the bottom of the hopper body, there is no water holding chamber for holding excess grain moistening water. The prior art grain moistening hopper can only discharge the grain moistening water by opening the drain port, and the excess grain moistening water cannot be discharged by closing the drain port. Those skilled in the art are well aware that the grain moistening step requires multiple grain moistening, and the grain moistening hopper needs to be left in the workshop for 4 to 5 hours after each grain moistening and water addition, so that the grain is fully in contact with the water and fully absorbs water. During this standing time, the prior art grain moistening hopper cannot keep the drain port open, because it will cause excess grain moistening water to flow to the workshop floor, resulting in poor environmental sanitation, so it is necessary to ensure that the drain port is closed. When closed, the excess grain moistening water cannot be discharged in time, which will cause the grain to become sour and deteriorate, affecting the quality of the wine. For this reason, the present application sets a water holding chamber connected to the air permeable cavity on the frame below the partition to store the excess grain moistening water generated when the grain moistening hopper is standing, which effectively avoids the technical problem of grain soaking in excess grain moistening water causing the grain to become sour and deteriorate. When the remaining moisture is required to be dumped, the moisture bucket is transported to the designated location and the check valve is opened to discharge the excess moisture to the designated location.

[0036] In order to increase the volume of the water chamber so that it can accommodate more excess grain-wetting water, the present application provides sealing plates 4 connected to the bucket body 2 at both ends of the bottom of the air-permeable chamber 304. The setting of the sealing plates enables the lower part of the air-permeable chamber to accommodate excess grain-wetting water.

[0037] In order to drain away the excess grain-moistening water temporarily stored in the water-holding chamber, the present application designs the bottom of the water-holding chamber 305 to be inclined toward one side of the check valve 306 .

[0038] The above specific implementation methods further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above are only specific implementation methods of the utility model and are not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
