Description

Technical Field

[0001] This utility model relates to the field of brewing equipment technology, and in particular to an automatic drainage and weighing device for a grain trough. Background Technology

[0002] In the production process of baijiu (Chinese liquor), "moistening the grains," also known as "moistening the raw materials," refers to the process of rinsing the brewing raw materials with water before steaming, allowing the raw materials to evenly absorb a certain amount of moisture. Traditional Daqu-style (large-grain) sauce-aroma baijiu production requires moistening the sorghum after crushing and before steaming. After moistening, the starch granules of properly crushed sorghum absorb an appropriate amount of water, causing the sorghum grains to swell and laying the foundation for subsequent steaming and gelatinization. Proper moistening not only provides the moisture required for fermentation but also removes some tannins and other substances from the sorghum, reducing the impact of tannins on the astringent taste produced in the first three rounds of distillation and improving the overall quality of the liquor.

[0003] Most existing grain-moistening devices unload by opening and closing the bottom of the hopper, requiring manual control of the valves for drainage. This results in high labor intensity for operators and severely restricts production efficiency. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] The following combination Figures 1-7 This invention describes an automatic drainage and weighing device for a grain hopper.

[0029] like Figure 1 and Figure 3As shown in the embodiment of this utility model, the automatic drainage and weighing device for the grain moistening hopper includes: a grain moistening hopper 1, a drainage pipe 2, a control valve 3, and a push rod 4. The grain moistening hopper 1 is equipped with a filter screen 15, which divides the space inside the grain moistening hopper 1 into a first chamber 101 and a second chamber 102. The first chamber 101 is used to hold the fermented grains, and the second chamber 102 is used to hold the water filtered from the fermented grains. The first end of the drainage pipe 2 is connected to the second chamber 102, and the second end of the drainage pipe 2 is located outside the grain moistening hopper 1. The control valve 3 is located on the drainage pipe 2 and outside the grain moistening hopper 1. When the push rod 4 extends, it can push the control valve 3 into the open state; when the push rod 4 retracts, the control valve 3 automatically resets to the closed state.

[0030] Specifically, after the sorghum is moistened, it is poured into the moistening hopper 1. The filter screen 15 inside the moistening hopper 1 filters out excess water from the mash. The water is stored in the second chamber 102. When drainage is needed, the push rod 4 extends, pushing the control valve 3 to open, and the water flows out through the drainage pipe 2; when drainage is complete, the push rod 4 retracts, and the control valve 3 automatically resets and closes.

[0031] In this embodiment, the push rod 4 can be a pneumatic push rod or an electric push rod. The operator only needs to jog the push rod 4 switch to control the extension or retraction of the push rod 4, without having to manually operate the control valve 3 switch, making the operation simpler and reducing labor intensity.

[0032] The automatic drainage and weighing device for grain hoppers provided in this embodiment of the utility model, by setting up a drainage pipeline, a control valve and a push rod, can open the control valve by controlling the extension of the push rod when drainage is needed, without the need for manual operation of the valve, thus improving work efficiency and reducing the labor intensity of operators.

[0033] like Figure 5 and Figure 6 As shown, the control valve 3 includes a valve body 31, a valve 32, and an elastic element 33. The valve body 31 is disposed in the drain pipe 2, and the valve 32 is rotatably connected to the valve body 31. The two ends of the elastic element 33 are respectively connected to the grain hopper 1 and the valve 32. When the push rod 4 extends, it can push the valve 32 to rotate, so that the valve body 31 is open. When the push rod 4 retracts, the elastic element 33 can drive the valve 32 to reset, so that the valve body 31 is closed.

[0034] Specifically, valve body 31 is installed in drain pipe 2, and valve 32 is used to control the opening and closing of valve body 31, thereby controlling the opening and closing of drain pipe 2. When push rod 4 is not in contact with valve 32, valve 32 blocks valve body 31. When push rod 4 extends and contacts valve 32, push rod 4 pushes valve 32 to rotate, valve body 31 is opened, and water in the second chamber 102 can be discharged through drain pipe 2. When valve 32 rotates, it causes elastic element 33 to extend. After drainage is completed, push rod 4 retracts, elastic element 33 returns to its original position, and elastic force drives valve 32 to rotate to its initial position, blocking valve body 31, thereby keeping drain pipe 2 in a blocked state.

[0035] like Figure 1 As shown, the wall of the grain hopper 1 is provided with a plurality of first heat dissipation holes 11, which are used to accelerate the cooling rate of the mash in the first chamber 101.

[0036] Furthermore, such as Figure 2 As shown, in order to further improve the cooling rate of the mash in the first chamber 101, a heat dissipation structure is also provided in the grain humidor 1. The heat dissipation structure includes a pair of heat dissipation plates 12, which are arranged in parallel. The two ends of each heat dissipation plate 12 are respectively connected to the opposite sides of the grain humidor 1. Each heat dissipation plate 12 is provided with multiple second heat dissipation holes 121.

[0037] Specifically, the mash is piled up in the first chamber 101, where the internal temperature is high and heat dissipation is slow. Based on this, two heat dissipation plates 12 are set in the grain warming hopper 1, with a certain gap between the two heat dissipation plates 12 to form heat dissipation vents. The heat of the mash on both sides of the heat dissipation plate 12 can be dissipated between the two heat dissipation plates 12 through the second heat dissipation holes 121 on the heat dissipation plate 12, thereby accelerating the cooling speed of the mash.

[0038] like Figure 2 As shown in the embodiment of this utility model, the wall of the grain hopper 1 is also provided with a temperature sensor, which is used to detect the temperature of the mash in the first chamber 101.

[0039] like Figure 2 and Figure 4 As shown, a pair of baffles 14 are also provided in the first chamber 101 of the grain hopper 1. The pair of baffles 14 are arranged opposite to each other on the filter screen 15 and respectively attached to the two opposite inner walls of the first chamber 101. The baffles 14 are used to prevent the water in the second chamber 102 from flowing back into the first chamber 101 through the filter screen 15 when the grain hopper 1 is turned over.

[0040] like Figure 1 and Figure 7 As shown in the embodiment of this utility model, the automatic drainage and weighing device for the grain hopper also includes a tank 5, which is located at the lower part of the grain hopper 1, and the second end of the drainage pipe 2 is connected to the tank 5.

[0041] Specifically, when the water in the second chamber 102 needs to be drained, the push rod 4 pushes the valve 32 to rotate, and the water flows into the tank 5 through the drain pipe 2.

[0042] Furthermore, such as Figure 7 As shown, the automatic drainage and weighing device for the grain hopper also includes a weighing sensor 51, which is installed in the tank 5 and is used to detect the weight of the water in the tank 5. A drain valve 52 is provided at the bottom of the tank 5. When the weight of the water in the tank 5 reaches a preset value, the drain valve 52 automatically opens to drain the water from the tank 5.

[0043] In the embodiments described above, the tank 5 and push rod 4 can be disposed on the bottom surface of the grain moistening hopper 1 or on other components. When the tank 5 and push rod 4 are disposed on the bottom surface of the grain moistening hopper 1, the grain moistening hopper 1 can automatically drain water regardless of its position; however, when the tank 5 and push rod 4 are disposed on other components, the grain moistening hopper 1 needs to be moved to a position adjacent to the tank 5 and push rod 4 to achieve automatic drainage. In the following embodiments, the disposal of the tank 5 and push rod 4 on other components will be described in detail.

[0044] like Figure 1 As shown in the embodiment of this utility model, the automatic drainage and weighing device for the grain hopper also includes a track 6, the grain hopper 1 can slide along the track 6, and the push rod 4 and the tank body 5 are both connected to the track 6.

[0045] Specifically, tank 5 is connected to track 6 via bracket 53. Push rod 4 is also connected to track 6. Track 6 has multiple stations, such as a grain moistening station and a drainage station. Grain moistening hopper 1 slides along track 6, performing different actions at each station. Specifically, after slid to the grain moistening station, the moistened sorghum mash is poured into the grain moistening hopper 1, where excess water is filtered out and the mash is cooled. Afterward, grain moistening hopper 1 slides along track 6 to the drainage station, where push rod 4 and tank 5 are located. Push rod 4 pushes control valve 3 to open, and water in grain moistening hopper 1 is drained into tank 5 through drainage pipe 2. When the weight of water in tank 5 reaches a preset value, drainage valve 52 opens, and water in tank 5 is drained into drainage ditch through pipe.

[0046] In this embodiment, the weighing sensor 51 detects the weight of the water in the tank 5 in real time. When the weight of the water detected by the weighing sensor 51 reaches a first preset value (which can be close to the weight of water when the tank 5 is completely full), the drain valve 52 opens. When the weight of the water detected by the weighing sensor 51 reaches a second preset value, the drain valve 52 closes. Optionally, the second preset value can be 0 or other weights. That is, the drain valve 52 can be closed when the tank 5 is emptied or when there is still a small amount of water remaining in the tank 5.

[0047] The automatic drainage and weighing device for grain hoppers provided in this embodiment can automatically drain the water in the grain hopper into the tank and automatically discharge it when the water content in the tank reaches a preset value. The whole process does not require manual opening and closing of the valve, realizing automatic drainage and automatic weighing, and improving the mechanization of grain hopper operation.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
