Description

Technical Field

[0001] The utility model belongs to the technical field of pure grain liquor production and manufacturing, and specifically relates to a grain fermentation tank. Background Technique

[0002] The grain fermentation tank is an important equipment for brewing and making other fermented foods. Its main function is to provide a suitable environment for the microorganisms in the grains to grow and reproduce fully, and to produce a large number of beneficial bacteria groups, so as to complete the fermentation process.

[0003] The prior art discloses a grain fermentation tank for liquor processing, including an installation platform. The fermentation tank body is embedded in the top of the installation platform. In this grain fermentation tank for liquor processing, by setting a pushing plate, a push board and a scraping board, when the feed valve is opened and the second servo motor is started, the push board drives the guide rail and the pushing plate to move, so that the pushing plate pushes the raw materials in the inner cavity of the fermentation chamber towards the feed valve direction. The raw materials fall into the conveyor through the feed hopper and the feed valve. The output end of the third servo motor drives the spiral feeding shaft to rotate, so that the spiral feeding shaft pushes the raw materials through the discharge valve to the collection equipment placed below the discharge valve. After the pushing plate moves to the designated position, the fourth servo motor is started, so that the push block drives the scraping board to move, so as to push the raw materials on the pushing plate and in the inner cavity of the fermentation chamber into the feed hopper through the scraping board, and the raw materials in the fermentation chamber can be cleaned up.

[0004] After retrieval, it is found that there is no related stirring measure in the prior art. This leads to the inability of the upper and lower layer materials to exchange positions during the fermentation process, resulting in incomplete fermentation. And when the staff manually opens the lid to stir the fermented material, air will penetrate into the fermented material, thus increasing the risk of fermentation failure. Moreover, the horizontal spiral conveying method involved in the prior art is prone to material leakage during use, resulting in incomplete material conveying, thus causing problems of material waste and difficult cleaning.

[0031] The working principle is as follows. By setting the through column 31, the scraping plate 32, the material turning plate 33 and the sealing cover plate 23, the through column 31 drives the scraping plate 32 to rotate and scrape on the inner wall of the fermentation tank 16. At the same time, due to the staggered setting of the material turning plate 33 and the shape of the material turning plate 33 being an L-shaped plate with a relatively large angle, during the rotation process, the material turning plate 33 turns and stirs the fermented material, promoting the exchange of upper and lower layer materials, thereby avoiding incomplete fermentation. At the same time, in cooperation with the use of the sealing cover plate 23, the fermented material is turned and stirred without the need to open the sealing cover 23, thus reducing the possibility of air penetration and avoiding the risk of fermentation failure.

[0032] As Figure 1 and Figure 2 shown in the figure, it includes that the mounting base 10 is a square box structure. A heat preservation cavity 13 is provided on the top surface of the mounting base 10. A discharge through hole 14 is provided on the bottom surface of the heat preservation cavity 13.

A threaded hole is provided inside the handle sleeve column 17. The threaded column 22 is threadedly connected with the handle sleeve column 17 through the threaded hole.

[0033] The working principle is as follows. When in use, it is necessary to first control the temperature in the temperature regulating chamber 19 within a suitable range, then place the collection box 11 into the collection bayonet 15, and then use the sealing cover 23 to seal the environment in the temperature regulating chamber 19 and the fermentation chamber 18 to prevent temperature loss, and then press the square cover of the insulation cover 12 on the top surface of the fermentation tank 16, and rotate the handle sleeve columns 17 at the four corners respectively so that the handle sleeve columns 17 are tightly connected to the threaded column 22. At this time, the annular column is clamped on the sealing cover 23 to compact it.

[0034] like Figure 3 and Figure 4 As shown, the sealing cover plate 23 is composed of a circular plate and a cylindrical cover, the cylindrical cover is clamped on the inner side of the annular column, a nail-shaped groove is opened in the center of the circular plate, the nail-shaped groove is rotatably connected to the through column 31, the through column 31 is rotatably connected to the shaft column 26, the cylindrical cover clamps and locks the shaft column 26, the top surface of the circular plate is fixedly provided with a motor 34, and the output end of the motor 34 is connected to the main bevel gear 35; Figure 3 , Figure 4 and Figure 5 As shown, the top surface of the shaft column 26 is fixedly connected with a first bevel gear 27, the top surface of the first bevel gear 27 is rotatably provided with a handle 25, the top surface of the cylindrical cover is provided with a limit opening 24, the limit opening 24 corresponds to the shape of the handle 25 and the first bevel gear 27, the handle 25 clamps and locks the shaft column 26 through the limit opening 24, the bottom curved surface of the shaft column 26 is fixedly connected with a conveying screw 28 and a plug 29, the conveying screw 28 and the plug 29 are located between the scraper 32 and the flipping plate 33, and the first bevel gear 27 is meshed with the main bevel gear 35 for transmission; as shown Figure 4 and Figure 5 As shown, four scrapers 32 and four flipping plates 33 are provided, and the four scrapers 32 are respectively distributed around the curved surface of the scraper 32, and the four flipping plates 33 are respectively fixedly connected to the inner wall surfaces of the four scrapers 32, and the top surface of the through column 31 is fixedly connected with the second bevel gear 30, and the second bevel gear 30 is meshed with the first bevel gear 27 and the same main bevel gear 35.

[0035] The specific implementation method is as follows. Before use, first lift the sealing cover plate 23. At this time, ensure that there is an angle between the sealing cover plate 23 and the fermentation chamber 18. At the same time, when the plug 29 blocks the discharge through hole 14, add fermentation materials into the fermentation chamber 18. Then check whether the temperature in the temperature adjustment chamber 19 is appropriate. After ensuring that the temperature is appropriate, lift the handle 25 and raise the shaft column 26 to the limit port 24. At this time, the handle 25 passes through the limit port 24. Rotate the handle 25 by 90 degrees, and the handle 25 is clamped at the limit port 24 to limit the position of the shaft column 26. At this time, the sealing cover plate 23 is stuck above the fermentation chamber 18, and the plug 29 blocks the discharge through hole 14. At this time, fix the handle sleeve columns 17 at the four corners of the heat preservation cover 12 to the threaded columns 22 at the four corners of the top surface of the fermentation tank 16. At this time, the heat preservation cover 12 tightly combines the sealing cover plate 23 and the fermentation chamber 18, and the device forms a fermentation environment; when stirring is required, unscrew the handle sleeve columns 17 at the four corners and open the heat preservation cover 12. Start the motor 34. It should be noted here that since the handle 25 drives the shaft column 26 to lift, the first bevel gear is far from the main bevel gear 35 at this time and cannot be driven. At the same time, install the control switch of the motor 34 on the top surface of the sealing cover plate 23 to control the start and stop of the motor 34. The motor 34 starts the rotation of the main bevel gear 35. The main bevel gear 35 meshes with the second bevel gear 30. The through column 31 at the bottom of the second bevel gear 30 drives the surrounding scraping plates 32 and turning plates 33 to rotate. Here, the turning plate 33 is designed as an L-shaped plate with a relatively large angle, and the four turning plates 33 are arranged in a staggered spiral orientation. During the rotation process, the turning plates 33 in different orientations will respectively mix and stir the fermentation materials at different depths. The scraping plate 32 scrapes the fermentation materials on the wall surface of the fermentation chamber 18. At this time, the mixing of the fermentation materials is realized; after fermentation is completed, open the heat preservation cover 12, rotate the handle 25 by 90 degrees, and press the shaft column 26. Stop pressing when the bottom surface of the first bevel gear touches the top surface of the second bevel gear 30. At this time, the plug 29 moves away from the discharge through hole 14, and the conveying screw 28 enters the discharge through hole 14. Start the motor 34. The main bevel gear 35 meshes with the drive rod first bevel gear 27 and the second bevel gear 30. The first bevel gear 27 and the second bevel gear 30 respectively drive the rotation of the shaft column 26 and the through column 31. At this time, the scraping plate 32 scrapes the inner wall of the fermentation chamber 18 to prevent materials from adhering to the inner wall. The turning plate 33 assists in conveying the materials, and the conveying screw 28 conveys the fermentation materials into the collection box 11. Finally, take out the collection box 11 to complete the collection.
