Description

Technical Field

[0001] The utility model relates to the technical field of automated winemaking, in particular to a high-efficiency grain moistening device. 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 steaming so that the raw materials can evenly absorb a certain amount of water. The traditional Daqu sauce-flavored 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 an appropriate amount of water, and the sorghum granules swell, laying the foundation for subsequent steaming and gelatinization. The traditional steps for moistening the grain are: dump the grain on the ground of the brewing workshop to form a pile, manually pour hot water on the grain pile, and use a shovel to stir it evenly while pouring water to allow the grain to fully absorb water. The water is generally poured twice, with an interval of 4 to 5 hours each time. After the two times of watering, the grain is left to stand for 16 hours before steaming.

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

[0032] The following is combined with Figures 1 to 5 The utility model is further described.

[0033] Example

[0034] In order to solve the technical problems existing in the background technology, the present application provides a high-efficiency grain moistening device.

[0035] The specific technical solution includes a feeding component 1 for conveying grain, a grain moistening hopper 2 for temporary storage and moistening of grain, a crane 3, a mixing component 6 and a water supply pipe 5. The feeding component 1 can adopt any one of a belt conveyor, a chain conveyor and a scraper conveyor, but from the perspective of cleaning and avoiding material snagging, the present application prefers a scraper conveyor. The above three feeding components are relatively mature equipment in the prior art, so their specific structures and principles are not described in detail here. The crane 3 is also a relatively mature equipment in the prior art, and is also a necessary equipment for each brewing workshop, and its specific structure and principle are not described in detail here.

[0036] Among them, the grain moistening hopper 2 is movably arranged below the end of the feeding component 1, and the grain transported by the feeding component 1 naturally flows into the grain moistening hopper 2. The water supply pipe 5 is arranged beside the feeding component 1 and is connected to the feeding component 1. It is used to replenish water to the grain in the grain moistening hopper 2. The water supply pipe 5 is connected to the water source through a water pump. The bottom of the water supply pipe 5 above the grain moistening hopper 2 is provided with a plurality of water supply holes (not shown in the figure). In order to improve the grain moistening effect, hot water is introduced into the water supply pipe 5 of the present application, and the temperature of the hot water is 95℃~100℃.

[0037] Because the mixing assembly 6 needs to be extended into the grain moistening hopper 2 when mixing grains, and after the mixing is completed, the mixing assembly 6 needs to be removed from the grain moistening hopper 2. Therefore, in order to realize the extension and retraction of the mixing assembly 6, the present application vertically connects a telescopic arm 4 to the traveling crane 3, and the end of the telescopic arm 4 is connected to the mixing assembly 6. The applicant is committed to the research of automated winemaking equipment, and in 2019 applied for an intelligent cellar opening device with a publication number of CN210884940U and a heavy-duty quick-change joint with a publication number of CN211761619U. The telescopic arm 4 in the present application can adopt the telescopic arm in the aforementioned intelligent cellar opening device. The telescopic arm in the present application is connected to the mixing assembly through a heavy-duty quick-change joint, and the quick switching connection between the cellar opening device and the mixing assembly is achieved through the heavy-duty quick-change device.

[0038] The specific technical scheme of the mixing component 6 is as follows: the mixing component 6 includes a top plate 601, a bottom plate 602 and a column 603 connected between the top plate 601 and the bottom plate 602, a motor 604 is arranged on the top plate 601, and the output end of the motor 604 is connected to a vertically arranged stirring shaft 605, the stirring shaft 605 is movably connected to the top plate 601 and the bottom plate 602 through a bearing, and a stirring blade 606 is arranged on the stirring shaft 605. The motor 604 in this embodiment adopts a reduction motor, which can be variable speed, and then adjust the rotation speed of the stirring shaft to make corresponding adjustments according to the amount of grain. The stirring shaft 605 and the stirring blade 606 are made of stainless steel.

[0039] The working principle of the mixing component 6 is as follows: the motor 604 is started, and the motor 604 drives the mixing shaft 605 to rotate, which drives the mixing blade 606 fixedly connected to the mixing shaft 605 to rotate synchronously with the mixing shaft 605, thereby mixing the grain in the grain moistening hopper 2 so that the grain is fully in contact with water.

[0040] In order to make the grains stirred more fully, the stirring blades 606 in the present application are spirally arranged on the stirring shaft 605 .

[0041] In order to facilitate the smoother insertion of the mixing component 6 into the grain in the grain moistening hopper 2, the present application sets the bottom plate 602 to be conical, and the diameter of the bottom plate 602 gradually decreases from top to bottom, so that the conical bottom plate 602 is easier to insert into the grain.

[0042] Because the grain conditioning hopper 2 needs to be moved away after the grain conditioning hopper 2 receives the material, in order to facilitate the horizontal transportation of the grain conditioning hopper 2, a chain conveyor 7 is provided on the ground below the feeding assembly 1 in this embodiment, and the grain conditioning hopper 2 is arranged on the chain conveyor 7. The chain conveyor is a relatively mature device in the prior art, and its specific structure and principle are not described in detail here.

[0043] Due to the influence of the gravity of the grain moistening water, part of the grain moistening water will accumulate at the bottom of the grain moistening hopper and needs to be discharged in time. If it is not discharged in time, on the one hand, the grain will become sour and deteriorate; on the other hand, it is difficult to control the moisture content of the grain. Therefore, the present application also provides a water filter pipe at the bottom of the grain moistening hopper, and a sealing plate for opening and closing the water filter pipe is provided at the bottom of the water filter pipe, so as to facilitate the discharge of excess water accumulated at the bottom of the grain moistening hopper.

[0044] Working principle of grain moistening: Take the grain moistening hopper with 1500Kg of grain for two times of moistening as an example. For the first time of grain moistening, the grain moistening hopper 2 is placed below the end of the feeding component 1, and the feeding component 1 transports the grain into the grain moistening hopper 2. At the same time, the water supply pipe 5 sprinkles the moistening water onto the grain in the grain moistening hopper 2. The moistening water added for the first time is 30% of the weight of the grain, that is, 450Kg. After the moistening water and grain are added, the grain moistening hopper 2 is transported to the bottom of the mixing component 6 through the chain conveyor 7. The driving 3 drives the mixing component 6 through the telescopic arm 4 to extend into the grain in the grain moistening hopper 2 to mix the grain so that the grain is fully in contact with the moistening water and the grain fully absorbs the moistening water. The grain moistening hopper is left to stand in the workshop for 4 to 5 hours, and the excess moistening water is discharged through the filter pipe after standing. For the second grain moistening, the grain moistening hopper 2 is conveyed to the bottom of the water supply pipe 5 by the chain conveyor 7. The water supply pipe 5 injects water into the grain in the grain moistening hopper 2. The water injection amount is 20% of the weight of the grain, that is, 300 kg. The grain moistening hopper 2 is then conveyed to the bottom of the mixing component 6 by the chain conveyor 7. The mixing component 6 mixes the grain. After mixing, the grain moistening hopper 2 is left to stand in the workshop for 16 hours. After standing, the excess grain moistening water is discharged through the filter pipe. Finally, the grain moistening hopper is conveyed to the next process for unloading and grain cooking.

[0045] It can be seen from the above structure and principle that, compared with the grain moistening device in the prior art, the present application can complete the grain moistening operation in the grain moistening hopper, while the existing grain moistening device needs to separately set up a grain moistening cabin to moisten the grain. Therefore, the present application reduces the layout of the grain moistening equipment and effectively reduces the production cost; in addition, the grain moistening cabin in the prior art needs to dump the grain into the grain moistening hopper for temporary storage or transportation after the grain moistening is completed. Therefore, the present application simplifies the grain moistening process and improves the grain moistening efficiency; furthermore, since the present application eliminates the use of the grain moistening cabin, only the grain moistening hopper needs to be cleaned after the grain moistening is completed, so the cleaning is more convenient and quick.

[0046] 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.
