Study On The Construction,Maintenance And Industrialization Of Luzhou Flavor Liquor Pits

Since the beginning of the 21st century,people’s living standards continue to improve.consumers are increasing quality requirements for liquor especially liquor flavor.In order to meet the needs of consumers living,liquor production technology is also ongoing improvements,and product’s quality has improved steadily,A variety of flavor emerge nowadays and Luzhou-flavor is one of them.Luzhou-flavor Liquor fermentation is a typical solid state fermenting process.Various micro-organisms,which came from air,water,material,da qu and mud pit,take part in the process of liquor fermentation and saccharification.Pit mud is the most important component of mud cellar,which is the indispensable basic conditions of Luzhou flavor liquor fermentation.And,The pit is the most basic infrastructure in the brewing process.This article is intended to start in the Luzhou-flavor liquor pit construction and maintenance of pit mud,and study on the method of building the Luzhou-flavor liquor pits.A comprehensive analysis from the pit of the layout of the basic structure,size,waterproof measures,and ultimately determine the best scheme of Luzhou-flavor liquor pits built.Furthermore,the paper was introduced a new building method of pit:mixed brick pit built,and put into trial production enterprise.The method is not only promote the cement kiln aging and improve the advantages of high quality product rate;but also has the characteristics of stable kiln structure.In the experiment,the cultivation and maintenance of pit mud were studied.High quality pit mud formula was determined by the following methods:temperature tracing,gas production,sensory evaluation and related physical and chemical indexes.The formula of pit mud was composed of loess 65%,field soil65%,pit mud25%,pond sludge 10%,soybean meal 1%,grains 16%,double bottom grains4%,ending liquor 10%,yellow water5%,Daqu4%,alcohol 1%,aged pit mud 1%,Concentrated caproic acid bacteria6%,K2HPO40.12%and urea0.12%.This paper through the analysis of two aspects,namely,the recovery of the production of the pit and the new opening of the pit,special measures were taken to conserve the pit mud.Also through mud reclamation technology to solve the problems in the process of Luzhou flavor liquor brewing in the various parts of the pit mud quality gap is large,has achieved remarkable results.This year,the average rate of annual premium liquor more than 10%(350mg/ml ethyl caproate)in the factory,to ensure the normal yield of liquor and increase the rate of liquor quality.This study provides a theoretical basis and industrial experience of Luzhou flavor liquor pits and pit mud structures,and have important guiding significance and application value of large-scale production of Luzhou flavor liquor.
