Description

Technical Field

[0001] The utility model relates to the technical field of wine filtration, and more specifically to a microfiltration membrane assembly for removing turbidity from fermented wine. Background Art

[0002] Baijiu has a complex aroma with esters as the main component. It is made from starch (sugar) raw materials through cooking, saccharification, fermentation, distillation, aging and blending, using koji and yeast as saccharification and fermentation agents. Strictly speaking, blended alcohol made from edible alcohol and edible spices cannot be considered as baijiu.

[0003] During the production of liquor, a wine filter device is used to filter the new liquor, thereby filtering out impurities in the new liquor and improving the quality and taste of the liquor. However, when using existing wine filters, most of them are static filtering designs, and when filtering, they only rely on water flow to the filter layer to filter out impurities in the liquor. This filtering effect is slow, which brings inconvenience to users and can no longer meet the needs of users. The existing patent is a wine filter device for the production of strong-flavor liquor, and the patent authorization number is CN216473158 U. The design of the stirring rod, activated carbon sleeve, PP cotton layer and microporous membrane layer enables the device to have a fast filtering function, which can quickly filter out large and small impurities in the liquor, thereby improving the efficiency and quality of the filtered liquor, increasing production capacity for users, bringing convenience to users, improving the practicality of the device, and meeting the needs of users.

[0004] However, when the wine in the patent authorization number CN 216473158 U flows into the filter element, it will interact with the PP cotton layer and the microporous membrane layer. The PP cotton layer can filter impurities of 0.25 microns, and the microporous membrane layer can filter impurities of 0.1 microns. Since the PP cotton cooperates with the microfiltration membrane to filter impurities in the wine, it cannot intercept impurities smaller than 0.1 microns, which easily causes the wine to become turbid and unclear, thereby affecting the filtration of the wine. Therefore, we proposed a microfiltration membrane assembly for deturbidity of fermented wine to solve the above-mentioned problems. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a microfiltration membrane assembly for deturbidity removal of fermented wine, which can filter the wine through the microfiltration membrane body and can intercept impurities larger than 0.1 microns. The filtered wine is passed through the second liquid inlet to the inner side of the second outer shell, so that the ultrafiltration membrane body filters the wine again and can intercept impurities of 0.1-0.05 microns. The filtered wine flows out through the liquid outlet, ensuring that the filtered wine is clear and not turbid.

[0007] 2. Technical solution

[0015] Furthermore, the microfiltration membrane body and the ultrafiltration membrane body are both hollow fiber membranes, and the material of the hollow fiber membrane is polyvinylidene fluoride.

[0016] Furthermore, the pore size of the microfiltration membrane body is 0.1 micron, and the pore size of the ultrafiltration membrane body is 0.05 micron.

[0017] Furthermore, a sealing cover is detachably connected to the bottom end of the second outer shell.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] (1) In this scheme, the wine is filtered by the microfiltration membrane body, and impurities larger than 0.1 microns can be retained. The filtered wine is passed through the second liquid inlet to the inner side of the second outer shell, so that the ultrafiltration membrane body can filter the wine again, and impurities of 0.1-0.05 microns can be retained. The filtered wine flows out through the liquid outlet, ensuring that the filtered wine is clear and not turbid.

[0021] (2) This solution utilizes the threaded connection between the external thread and the internal thread, and uses the second sealing rubber ring to fill the gap at the junction of the first outer shell and the second outer shell, so as to facilitate the disassembly between the first outer shell and the second outer shell, thereby facilitating the cleaning of the microfiltration membrane body, and facilitating the cleaning of the ultrafiltration membrane body inside the second outer shell by removing the sealing cover.

[0036] It should be noted that when the microfiltration membrane assembly for deturbidity removal of fermented wine is in use, the wine to be filtered is introduced into the inner side of the first outer shell 1 through the first liquid inlet 5, and the first sealing rubber ring 6 is used to fill the gap at the junction of the first guide head 3 and the first outer shell 1, so that the microfiltration membrane body 4 filters the wine and can intercept impurities larger than 0.1 microns.
