Rice wine is a national wine of our country with a long history and excellent products. However, the traditional method of producing rice wine is very old, primitive and old. After the founding of new China, with the improvement and advancement of science and technology, people gradually understand the scientific principles of winemaking and begin to Scientific research and summary of rice wine production and technology. In the process research on the non-biological stability of rice wine, it has been widely used to clarify the filtration of rubber and cotton cake to the diatomaceous earthfiltration method so far, and it has been difficult to obtain satisfactory results for the long-term non-biological stability of rice wine.
In recent years, the membrane separation technology has achieved good results in the beer and wine industry for pure draft beer. Therefore, it has gradually been valued by domestic large and medium-sized rice wine producers for research and application. The application of membrane separation technology in the filtration of rice wine has confirmed that the domestic cross-flow membrane filtration system equipment separates the rice wine, the gloss is transparent, the wine is bright, the non-biological stability of the rice wine is obviously improved, the shelf shelf life is prolonged, and the original flavor is maintained. Features, while the wrong filter membrane filter rice wine is easy to operate, not easy to block. The effect is stable, the production cost is low, and the utility model has high practical value. The domestic cross-flow membrane equipment is now filtered to improve the quality of rice wine products. The technical performance and economic analysis are as follows.
The characteristics of domestic membrane filtration rice wine, liquid cross-flow membrane sterilization microfiltration system, its core separation membrane has high strength, long life, acid and alkali resistance, corrosion resistance and other excellent characteristics and can be properly adjusted for liquid diameter. Through automatic control, the system can realize intermittent frequency conversion recoil negative pressure pulsation, steam and water cleaning and other international advanced membrane application technologies in the appropriate process. It also has the functions of emergency protection shutdown and optional online turbidity detection, and automatic shutdown after production. The machine system has the following characteristics:
The quality of the filtered product is excellent, the liquid clearing transparency is high, and the sterilization effect is over 99.9%.
It can be adapted to high turbidity and high viscosity liquid filtration. Fine filtration is completed once. It does not need traditional cotton cake, and diatomaceous earth filter is used for pre-filtration.
The unique cross-flow process design and automatic self-cleaning in the operation process ensure the continuity and scale of separation. Compared with the traditional membrane separation equipment, the separation effect is improved by more than 40%, and the anti-clogging performance is excellent.
It has high automation, easy operation, stable separation performance and low cost of use. Nowadays, all rice wine enterprises use the process of freezing and filtering on the turbidity of rice wine to solve the problem of precipitation of rice wine. This requires not only dual equipment investment, but also the need to increase the freezing settling tank and insulation facilities, so the investment is large, the process not only requires the operating cost of filtration, but also costs 10-20 yuan for each ton of rice wine processed. The membrane separation technology has a simple separation process, and the price of the membrane has been reduced to a reasonable level in recent years. Therefore, the use of the wrong filtration and classification membrane separation technology can solve the precipitation problem of rice wine, and has certain advantages in economy.
