High-performance ceramic membrane assembly applied to beer filtering field

Abstract

The invention relates to the field of ceramic membrane assemblies, and particularly discloses a high-performance ceramic membrane assembly applied to the field of beer filtration. The high-performance ceramic membrane assembly comprises a plurality of ceramic membrane sheets and a tube shell used for installing the ceramic membrane sheets, wherein the inner wall of the tube shell and the ceramic membrane sheets are coated with a filtration-aiding adsorption layer formed by a filtration-aiding adsorbent, and the preparation method of the filtration-aiding adsorbent comprises the following steps: 1, adding gelatin and rice husk powder into a cerous nitrate solution with a concentration of 8-12%, and uniformly mixing and stirring to obtain particle slurry; and 2, dissolving hydroxypropyl chitosan in a sodium hydroxide solution to prepare a hydroxypropyl chitosan solution, adding the particle slurry while stirring, and adding a promoting solution containing calcium ions according to the amount of 1-2 mL / g by taking the total mass of the hydroxypropyl chitosan solution and the particle slurry as a reference to prepare the filtration-aiding adsorbent. According to the invention, the ceramic membrane assembly is good in beer filtering effect, and the filtered beer is good in fragrance and taste after being placed for a long time.

Description

technical field [0001] This application relates to the field of ceramic membrane modules, more specifically, it relates to a high-performance ceramic membrane module applied in the field of beer filtration. Background technique [0002] At present, ceramic membranes are widely used in the world due to their high separation efficiency, stable effect, good chemical stability, acid and alkali resistance, organic solvent resistance, bacteria resistance, simple separation process, low energy consumption, easy operation and maintenance, and long service life. Food, biomedicine, fine chemical industry and many other fields. [0003] In the food field, in the production process of beer, grain crushing, saccharification, gelatinization, washing, boiling, fermentation and filtration to form beer, after the fermented liquid is mature, in the filtration step, multiple tubular ceramic membranes are usually used filter in series. The inventor found that no matter how many tubular cerami...

AI Technical Summary

Problems solved by technology

The inventor found that no matter how many tubular ceramic membranes are connected in series to filter beer, the beer before and after filtration not only has a low rate of decrease in turbidity, but the filtering effect is not good, and the aroma and taste of the beer become worse after being packaged and placed for a long time
