Description

Technical Field

[0001] This utility model relates to the field of rice wine production technology, specifically to a fermentation tank cleaning device for rice wine production. Background Technology

[0002] In the fermentation process of rice wine, the impact of the amount of koji added on various physicochemical properties and sensory evaluation is comprehensively considered. Insufficient koji will lead to a lack of saccharifying and alcohol-producing enzymes, resulting in a slower conversion of sugar into alcohol, lower alcohol content, and thus delaying the entire fermentation cycle. The amount of koji added affects the chemical reactions during fermentation; an appropriate amount ensures sufficient fermentation and maximizes the conversion of sugar into alcohol. Too little koji will result in insufficient flavor compounds, leading to a weak aroma and taste. Using 500g of glutinous rice as a base, 10g of dried bayberries were added to each of the numbered groups, with a material-to-liquid ratio of 3:1. Koji was added to different groups at proportions of 0.8%, 1.0%, and 1.2% of the glutinous rice weight, with two parallel groups. Fermentation was carried out continuously at 30℃ for 7 days. The total sugar, total esters, total acid, and fusel oil content of the numbered finished products were measured daily, and sensory evaluations were compared to determine the optimal amount of alcohol added.

[0003] For example, Chinese patent CN222241781U discloses a cleaning device for fermentation tanks used in rice wine production. In this solution, through the cooperation of a servo motor, a mounting plate, a brush, and an adjustment mechanism, the scraper first scrapes off the glutinous rice material attached to the inner wall of the fermentation tank, and then the brush cleans the inner wall of the fermentation tank, making the fermentation tank more thoroughly cleaned. At the same time, the adjustment mechanism can adjust the position of the scraper and the brush, so that the device can adapt to fermentation tanks of different sizes.

[0004] Based on the above-disclosed technical solutions and existing technologies, some rice wine fermentation tank cleaning devices only have vertical brushes on both sides, and no brushes are installed at the bottom of the tank, which cannot completely remove the residue that falls to the bottom of the tank. At the same time, the bottom brushes of some devices do not have an adjustment function, and cannot better adapt to fermentation tanks with different bottoms. Therefore, we propose a fermentation tank cleaning device for rice wine production, in which the bottom brushes are adjustable to adapt to fermentation tanks with different bottoms, thereby improving the practicality of the fermentation tank cleaning device for rice wine production.

One end of the two corrugated protective covers is fixedly connected to the top and bottom of the nut seat 205, and the other end of the two corrugated protective covers is fixedly connected to the top and bottom of the inner side of the mounting shell 201. The corrugated protective covers prevent impurities from falling on the screw 202 when cleaning the tank 4, thus affecting the transmission of the screw 202. The surface of the bottom plate 1 is connected to the tank 4 through the support column 3. The support column 3 is used to support the tank 4 and connect the bottom plate 1 and the tank 4.

[0026] The cleaning component 5 includes a central shaft 6, a discharge pipe 18 at the bottom of the tank 4, brushes 19 on both sides of the bottom of the central shaft 6, the bottom of the central shaft 6 being inside the discharge pipe 18, a servo motor 7 fixedly connected to the top of the central shaft 6, and telescopic rods 8 connected at equal distances on both sides of the central shaft 6. The telescopic rods 8 consist of a round tube, a spring, and a short rod, with the short rod inside the round tube. After the servo motor 7 is started, the central shaft 6 begins to rotate, and the telescopic rods 8 extend and retract through centrifugal force. A cleaning brush 9 is fixedly connected to one end of the telescopic rod 8. The extension and retraction of the telescopic rod 8 allows the cleaning brush 9 to better fit the inner wall of the tank 4 for cleaning. A rubber brush 10 is rotatably connected to the bottom of the left cleaning brush 9. A groove for connecting the rubber brush 10 is opened at the bottom of the left cleaning brush 9, and a hole for fixing a gravity block 11 is opened on the upper surface of the rubber brush 10.

[0027] Two gravity blocks 11 are provided on the top surface of the rubber brush 10. When the gravity blocks 11 fall, they drive the rubber brush 10 to move and fit against the bottom of the can 4. A magnetic strip 12 is fixedly connected to one side of the top surface of the rubber brush 10. One end of the rubber brush 10 is connected to the lower end of the central shaft 6. A hole is opened on the surface of the central shaft 6 for the rubber brush 10 to pass through. A magnetic sheet that attracts the magnetic strip 12 is fixedly connected to the top of the hole.

Nut blocks 16 are threadedly connected to both sides of the outer side of the bidirectional lead screw 14. Clamping plates 17 are fixedly connected to the bottom of the nut blocks 16. After the starter motor 15 is turned on, the bidirectional lead screw 14 starts to rotate, causing the nut blocks 16 to drive the clamping plates 17 to move and clamp the tank 4. Symmetrical connecting rods 20 are provided on one side of the two clamping plates 17. One end of the connecting rod 20 is slidably connected to the fixed plate 13.

[0029] The implementation principle of a fermentation tank cleaning device for rice wine production in this application embodiment is as follows: When using the fermentation tank cleaning device for rice wine production, first fix the tank body 4 on the base plate 1, and then start the lifting component 2 to adjust the height to a suitable position.

[0030] When the starter motor 15 is turned on, the bidirectional lead screw 14 begins to rotate, and the nut block 16 drives the clamping plate 17 to move, clamping the tank 4 and thus fixing the tank 4.

[0031] Next, the servo motor 7 is started to drive the central shaft 6 to start rotating. The telescopic rod 8 extends and retracts, causing the cleaning brush 9 to adhere to the inner wall of the tank 4 for cleaning. At the same time, the gravity block 11 falls and causes the rubber brush 10 to move and adhere to the bottom of the tank 4. The rubber brush 10 cleans the impurities that fall to the bottom of the tank 4.

[0032] Impurities are discharged from the discharge pipe 18, while the central shaft 6 drives the brush 19 to clean the inner wall of the discharge pipe 18, preventing impurities from accumulating inside the discharge pipe 18 and reducing cleaning efficiency.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
