查询词典 alumina

The precipitate in liquor is a common problem in distilleries which have to tackle with and the frequent causations are as follows: floccule induced by three kinds of higher fatty acid ethyl ester and microthermal storage and filtration could prevent it; white flakes of precipitate induced by containers for liquor storage such as aluminous pots which produced alumina and mare nectaris which dissolved into coating and then caused precipitate; precipitate induced by undergrade additives and CP grade or AR grade additives could prevent it; precipitate induced by water quality and strict management of water quality could prevent it; precipitate induced by packing materials and the solution was acid water washing for new bottles and liquor filling after the inner of the bottles was completely dry.

白酒产生混浊沉淀是一普遍问题，常见的有絮状沉淀，主要由3种高级脂肪酸乙酯引起，可于低温贮存过滤；白色片状沉淀，由贮酒容器引起，铝罐贮酒，会产生氧化铝溶入沉淀，最好不用铝罐贮酒；酒海贮酒会溶入涂料，造成沉淀，酒海贮酒不宜过久；由劣质添加剂引起，最好使用CP级或AR级添加剂；水质引起，对水处理应严加管理；包装材料引起，新瓶应用酸性水洗，且须控干水后再灌酒。
