Rice Wine Production Process for Membrane Filtration Tech

Background Introduction

Rice wine is a sweet fermented wine made from steamed glutinous rice mixed with wine yeast. It features a simple brewing process, sweet and mellow taste, and extremely low alcohol content, which makes it widely popular among consumers. The original rice wine contains a large number of impurities, mainly including glutinous rice residues, starch, fibers, yeast, colloids, suspended solids and other substances. These impurities lead to poor taste and excessive precipitation of rice wine. Therefore, the filtration and impurity removal section is extremely important in the rice wine production process. Traditional filtration methods mostly adopt diatomaceous earth filtration and plate and frame filtration, which cannot completely intercept macromolecular impurities and only achieve temporary clarification of the filtrate. Under the influence of time, temperature and electric charge, dissolved impurities will re-flocculate to form visible foreign matters, causing turbidity and precipitation of the wine body and affecting its sensory quality and overall grade.

Advantages of Membrane Filtration Technology in Rice Wine Production

① Adopts advanced nano-scale filter materials with strong selective separation performance and thorough impurity separation. The treated wine body is clear and transparent, with a sterilization and impurity removal rate of over 99%;

② Adopts cross-flow operation process without adding filter aids, avoiding the introduction of new impurities and solving the problems of pollution and blockage;

③ Pure physical operation at room temperature without chemical reactions, which does not damage heat-sensitive components or affect the original flavor of rice wine;

④ Features an advanced modular design with convenient filter material replacement and simple operation;

⑤ High degree of automation with safe and reliable operation, effectively reducing labor intensity. The membrane filtration process is carried out in a closed container to realize clean production;

⑥ Equipped with 304 or 316L stainless steel sanitary materials, complying with GMP and QS quality standards;

⑦ Membrane elements with large filling area, enabling the system to occupy a small floor space. It is convenient for technical renovation, expansion and new project construction, effectively reducing production costs and investment.
