A filtration device for liquor production

Abstract

This utility model relates to the field of liquor production technology and discloses a filtration device for liquor production, including a base. A first filter tank and a second filter tank are fixedly installed on top of the base. The first filter tank contains a coarse filter cylinder, and the second filter tank contains a fine filter cylinder. The filtration aperture of the fine filter cylinder is smaller than that of the coarse filter cylinder. This utility model utilizes a drive motor, connecting shaft, two driving bevel gears, a driven bevel gear, a rotating shaft, a limiting seat, and a limiting block to facilitate the synchronous rotation of the coarse and fine filter cylinders. The centrifugal force generated by the rotation of the coarse filter cylinder separates impurities from the liquor, performing preliminary filtration before the liquor is discharged into the fine filter cylinder for secondary filtration.

Description

Technical Field

[0001] This utility model relates to the field of liquor production technology, and more specifically to a filtration device for liquor production. Background Technology

[0002] Baijiu (Chinese white liquor) is a distilled spirit made primarily from grains, using daqu (large koji), xiaoqu (small koji), bran koji, enzymes, and yeast as saccharification and fermentation agents. The process involves cooking, saccharification, fermentation, distillation, aging, and blending, making its brewing process complex and meticulous. During baijiu brewing, insoluble impurities (such as mash and microbial remains) are produced. These impurities cause turbidity and affect the taste, necessitating filtration. Multi-stage filtration gradually removes impurities of different pore sizes, ensuring a clear and transparent liquor. For example, two-stage filtration is suitable for basic filtration needs, removing impurities through coarse and fine filtration stages. This method is simple and low-cost. Various filtration methods exist for baijiu, such as centrifugal filtration, which uses high-speed rotation to separate impurities from the liquor, improving clarity and stability. However, current centrifugal filtration technology can only perform single-stage filtration and cannot simultaneously perform two-stage filtration, requiring further improvement.

All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example 1:

[0020] like Figure 1-4 As shown, a filtration device for liquor production includes a base 1. A first filter tank 3 and a second filter tank 4 are fixedly installed on the top of the base 1. The first filter tank 3 is equipped with a coarse filter cylinder 34, and the second filter tank 4 is equipped with a fine filter cylinder 43. The filtration pore size of the fine filter cylinder 43 is smaller than that of the coarse filter cylinder 34. The pore size of the coarse filter cylinder 34 can be 0.22 micrometers, which is mainly used to remove large particulate impurities. The pore size of the fine filter cylinder 43 can be 0.1 micrometers, which further purifies the liquor and retains flavor substances.

Two driving bevel gears 23 are fixedly installed on the outer wall of the connecting shaft 22. Two rotating shafts 25 are symmetrically rotatably installed on the top of the protective cover 2 via bearings. A driven bevel gear 24 is fixedly installed at the bottom of each of the two rotating shafts 25. The driven bevel gear 24 is located above the driving bevel gear 23 and meshes with the driving bevel gear 23. The first filter tank 3 and the second filter tank 4 are inside... Each part is equipped with a limiting seat 26 at the bottom. The outer wall of the limiting block 35 is engaged with the inside of the limiting seat 26. The top ends of the two rotating shafts 25 extend into the inside of the first filter tank 3 and the second filter tank 4 and are fixedly installed at the bottom of the limiting seat 26. The protective cover 2 is provided to protect the drive motor 21, the connecting shaft 22, the driving bevel gear 23 and the driven bevel gear 24. The cooperation of the drive motor 21, the connecting shaft 22, the two driving bevel gears 23, the two driven bevel gears 24 and the two rotating shafts 25 facilitates the synchronous driving of the two limiting seats 26 to rotate. The limiting seat 26 drives the coarse filter cylinder 34 or the fine filter cylinder 43 to rotate through the limiting block 35. The centrifugal force generated by the rotation of the coarse filter cylinder 34 or the fine filter cylinder 43 is used to filter the liquor.

[0022] A No. 1 filter tank 3 has a No. 1 tank cover 31 attached to its top. A No. 1 clamp 32 is provided between the No. 1 filter tank 3 and the No. 1 tank cover 31. The No. 1 filter tank 3 and the No. 1 tank cover 31 are fixedly installed together by the No. 1 clamp 32. An inlet pipe 33 is fixedly installed in the middle of the top of the No. 1 tank cover 31. A No. 2 filter tank 4 has a No. 2 tank cover 41 attached to its top. A No. 2 clamp 42 is provided between the No. 2 filter tank 4 and the No. 2 tank cover 41.

When the No. 1 tank cover 31 and the No. 2 tank cover 41 are removed, the coarse filter cartridge 34 and the fine filter cartridge 43 can be taken out from the No. 1 filter tank 3 and the No. 2 filter tank 4 for cleaning or replacement.

[0023] A liquid pump 6 is fixedly installed on the top of the protective cover 2. A guide pipe 5 is fixedly installed at the input end of the liquid pump 6.

Solenoid valves are installed on both the guide pipe 5 and the drain pipe 8. Through the cooperation of the guide pipe 5, the liquid pump 6 and the hose 7, it is convenient to draw the wine that has been initially filtered inside the No. 1 filter tank 3 into the No. 2 filter tank 4, and further filter it through the fine filter cartridge 43. The drain pipe 8 facilitates the discharge of the wine that has been filtered inside the No. 2 filter tank 4.

[0024] The bottom of both the No. 1 tank cover 31 and the No. 2 tank cover 41 are fixedly connected with protective rings 36. The tops of the coarse filter cylinder 34 and the fine filter cylinder 43 are movably disposed inside the protective ring 36. A sealing gasket 37 is fixedly installed inside the protective ring 36. The tops of the coarse filter cylinder 34 and the fine filter cylinder 43 overlap the bottom of the sealing gasket 37. The sealing gasket 37 is used to increase the sealing performance of the coarse filter cylinder 34 and the fine filter cylinder 43 inside the protective ring 36. The protective ring 36 is also used to protect the top of the coarse filter cylinder 34 or the fine filter cylinder 43.

[0025] Limiting rings 38 are fixedly installed on the upper part of the interior of both filter tank 3 and filter tank 4. The upper part of the outer wall of the coarse filter cylinder 34 and the fine filter cylinder 43 is set inside the limiting rings 38. Multiple balls 39 are rotatably embedded inside the limiting rings 38. One side of the multiple balls 39 overlaps the upper part of the outer wall of the coarse filter cylinder 34 and the fine filter cylinder 43. By using the setting of the limiting rings 38 and the multiple balls 39, the upper part of the outer wall of the coarse filter cylinder 34 or the fine filter cylinder 43 can be limited. When the coarse filter cylinder 34 or the fine filter cylinder 43 rotates, it can drive the multiple balls 39 inside the limiting rings 38 to rotate.

[0026] In summary, as Figure 1-4As shown, this filtration device for liquor production, in use, the liquor enters the coarse filter cylinder 34 inside the first filter tank 3 through the inlet pipe 33. At this time, the output end of the drive motor 21 drives the connecting shaft 22 to rotate. The connecting shaft 22 synchronously drives the two driving bevel gears 23 to rotate. The two driving bevel gears 23 drive the two driven bevel gears 24 to rotate. The two driven bevel gears 24 drive the coarse filter cylinder 34 and the fine filter cylinder 43 to rotate through the rotating shaft 25, the limiting seat 26 and the limiting block 35. The coarse filter cylinder 34... The centrifugal force generated by the rotation separates impurities from the wine. After the wine is initially filtered, the wine filtered inside the No. 1 filter tank 3 is drawn into the fine filter cartridge 43 inside the No. 2 filter tank 4 through the cooperation of the guide pipe 5, the pump 6 and the hose 7. The fine filter cartridge 43 is rotated to perform secondary filtration. After secondary filtration, the wine is discharged through the drain pipe 8. When the wine continuously enters the No. 1 filter tank 3 and the No. 2 filter tank 4, this method can drive the two filter cartridges to rotate simultaneously to perform two-stage filtration of the wine.
