Description
Technical Field
The utility model belongs to the technical field of wine making, particularly relates to a device for removing turbid matters in white spirit, and particularly relates to a device for removing turbid matters in white spirit by coupling activated carbon adsorption and membrane filtration.
Background
The wine base of the winery generally contains impurities such as turbid matters, the components of the turbid matters are mainly high-grade fatty acid ethyl ester, when the alcoholic strength of the wine base is reduced or the wine base is frozen, the high-grade fatty acid ethyl ester in the wine is reduced in solubility, the wine is separated out and is in a white flocculent state, and the appearance of the wine is turbid. Particularly in northern regions, wine is easily cloudy outdoors due to cold weather. These turbidity impurities affect not only the transparency of the liquor but also the flavor, taste and purity of the liquor, and it is desirable to remove as much as possible from the liquor. Basically all wineries have a turbidity removal process before leaving the factory. In the early stage, methods such as silk cloth filtration, absorbent cotton filtration, filter paper filtration, sand filter stick filtration and the like are adopted. Plate-type filter pressing, activated carbon adsorption, diatomite filtration, molecular sieve medium filtration and the like are adopted later, although the adopted process is more and more advanced, the problems exist in the using process, such as easy saturation, black pollution and precipitation caused by a common activated carbon adsorption method, and large loss of aroma components; the traditional freezing and diatomite filtration method needs to freeze a large amount of raw wine to about-15 ℃ and then adopts a large amount of diatomite for filtration, so that more aroma-producing substances in the wine are removed, the equipment investment is large, the required energy consumption is high, the yield is low, a large amount of solid waste is generated, resources are wasted, the environment is polluted, in addition, the diatomite filtration is easy to leak soil and liquid, the phenomena of filtration failure and the like are easily caused, and the filtration quality and the quality of the white wine are seriously influenced. The conventional nanofiltration/reverse osmosis membrane is also applied to experiments of removing turbidity of the white spirit, but the membrane material is intolerant to spirit swelling, so that the permeation flux is very small, and a large part of fragrant substances are intercepted, so that the taste of the white spirit is greatly changed.
