Abstract


7 resin to simulate the wine sample assay , choose # 6 the resin the higher alcohol removal rate of up to 62.8% ; through 6 # resin adsorption experiments confirmed the rice wine wine esters 6 # ester resin wine class has little effect . Choice # 6 resin as a resin of the present experiment . 6 # resin model wine Alcohol kind of experiment , orthogonal and dynamic adsorption experiments operating conditions can be drawn : rice wine alcohol for 10 % to 20 % ( v / v ) , pH value of 4 to 5.5 adsorption temperature of 20 ℃. Wherein the resin added in an amount of 5% , the the static processing time for 40min , a higher alcohol removal rate of 62.39% ; dynamic process , the linear velocity of 3.05m / h the higher alcohol removal rate of 76.80% . 6 # of resin through the wine static and dynamic applications test DRAWN: wherein the static adsorption , the resin is added in an amount of 5% , an adsorption time of 20min , higher alcohol removal rate of 47.86% ; dynamic adsorption experiments , the linear velocity for the 4m / h , higher alcohol removed rate of 68.2% . This condition, the treatment wine physical and chemical indicators close to original wine tasting with the original wine is basically the same . 6 # resin adsorption of the higher alcohols conventional ( alkali salt alcohols ketone ) activation , boiled activation , the fumigation activation comparative experiments : General ( alkali salt of alcohol and ketone ) resin activation method is more appropriate . Resin to reduce the higher alcohol in the finished rice wine is a simple and effective measures , the paper measures the basis of scientific practice . And to some extent, to protect the health of the drinker , but also improve the quality of products, increase the economic benefits for the enterprise . Has been applied in the actual production start .
