Thick mash alcohol fermentation process for mixing tapioca by using molasses hydrolyzate

Abstract

The invention relates to a thick mash alcohol fermentation process, in particular to a thick mash alcoholic fermentation process for mixing tapioca by using molasses hydrolyzate, which comprises the following steps of hydrolyzing the molasses; then mixing the tapioca with the molasses hydrolyzate and certain amount of water to ensure that the total amount of the tapioca pulp reaches 27.5 to 28.5(g / 100mL), wherein the total sugar content of the molasses hydrolyzate is 10 to 20% of the total sugar of the tapioca; the concentration of the obtained fermented mash alcohol is higher than 15.0(v / v) after the procedures of liquefaction, sterilization, saccharification, fermentation and the like. In the invention, the molasses hydrolyzate with lower viscosity is mixed with the tapioca for pulping, which increases the initial sugar concentration to meet the requirement of thick mash fermentation, and keeps good fluidity in the gelatinization and fermentation processes of the pulp material; the invention can be used for continuous production of thick mash alcohol fermentation; the molasses hydrolyzate can be utilized by alcohol yeast at high efficiency; and the invention has the advantages of good fermentation effect and low production cost.

Description

【Technical field】 [0001] The invention relates to a thick mash alcohol fermentation process, in particular to a thick mash alcohol fermentation process using molasses hydrolyzed liquid to adjust cassava flour. 【Background technique】 [0002] Guangxi is the main production area of ​​alcohol production in my country, and its main raw materials are cassava and molasses. The degree of fermented fermented mash produced by general enterprises using these two kinds of raw materials alone has only 9%~10% (v / v), making its equipment utilization rate, labor productivity, energy utilization rate on the low side, and production cost is higher. The improved method is to use thick mash alcohol fermentation, which is a high-intensity fermentation method, which has the advantages of high equipment utilization, low distillation energy consumption, low production cost and easy handling of distiller's grains. It is an alcohol with great application value. fermentation technology. The premise...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved in the present invention is: provide a kind of thick mash alcohol fermentation process that utilizes molasses hydrolyzed liquid to carry out cassava flour slurry adjustment, to solve the excessive viscosity of cassava flour slurry gelatinization, liquefaction, saccharification process and The fluidity of the fermented mash is poor, and then solve the problem that the cassava flour thick mash alcoholic fermentation is difficult to be directly applied in continuous production, to overcome the deficiencies in the above-mentioned prior art
