Embodiment

[0017] Embodiment: (the total sugar content of molasses hydrolyzate accounts for 20% of the total sugar of powder slurry)

[0018] A kind of thick mash alcoholic fermentation process that utilizes molasses hydrolyzate to carry out cassava flour slurry adjustment, comprises the following steps:

[0019] (1) Hydrolysis of molasses: put molasses in a 1000mL beaker, add water to dilute to 30°Bx, then adjust pH 2.4 with 20% sulfuric acid solution, keep it in a sterilizer at 125°C for 40min, take it out and let it stand for 1h. The precipitate was separated, and the separated supernatant was neutralized to pH 6.0 with 6 mol / L sodium hydroxide solution to obtain a molasses hydrolyzate with a sugar content of 19.2 g / 100 g.

[0020] (2) Utilize molasses hydrolyzate to carry out cassava flour mixing: take by weighing 18.38kg starch content and be the molasses hydrolyzate that makes in 70% dry cassava flour and 18.59kg step (1), and add 20kg water and mix, place In a 100L fermenter, add...

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...
