Problems solved by technology

However, the pulverization process has high energy consumption, high noise, large dust, and is easy to wear. In addition, using the traditional method to ferment acorns requires removal of tannins before fermentation, and the steam explosion method is used to process acorns. Most of the tannins are dissolved in water after steam explosion treatment, which provides conditions for the next step to directly separate and purify tannins with the filtrate after steam explosion

Embodiment 1

[0022] Take 100g of fresh acorns, put them into a steam blaster, process them for 3 minutes under the condition of 0.9MPa, and blast them. Filter the steam explosion material and separate it into two parts: filtrate and filter residue. The filter residue has not been subjected to enzymatic hydrolysis treatment, and it is directly inserted into yeast, fermented at 35°C for 72 hours, and the actual alcohol yield is 0.88% (alcohol g / dry steam explosion material g) and collected by distillation Alcohol.

Embodiment 2

[0024] Take 100g of fresh acorns, put them into a steam blaster, process them for 3 minutes under the condition of 1.5MPa, and blast them. Filter the steam explosion material, separate it into filtrate and filter residue, add water according to the ratio of steam explosion material: water 1:2, add amylase at 10u / g, cook at 90°C for 30min, after cooling, add saccharification at 200u / g Enzyme, water bath at 60°C for 1 hour, ferment at 35°C for 72 hours, and collect alcohol by distillation.

[0025] implementation benefit 3

[0026] Take 100g of fresh acorns, put them into a steam blaster, process them for 3 minutes under the condition of 2.2MPa, and blast them. Filter the steam explosion material, separate it into filtrate and filter residue, add water according to the ratio of dry steam explosion material: water 1:2.3, add amylase at 10u / g, cook at 90°C for 30min, after cooling, add 200u / g Glucoamylase, water bath at 60°C for 1 hour, ferment at 35°C for 72 hours, and collect ...

Abstract

The invention belongs to the field of fermentation of starch-bearing materials and relates to a method for pretreatment of acorns by means of vapor explosion, wherein the acorns are pretreated by vapor explosion. The treatment method is different from the prior method for treating the starch-bearing materials, not only can achieve the aim of crushing which can be only achieved in the prior method but also lays a foundation for further separation and purification of tannin by means of making a composition in acorn kernels for influencing ethanol fermentation- the tannin mostly dissolved into liquefied vapor in the form of filtrate. Compared with the prior method, the method is economic and environment-friendly. Moreover, comprehensive utilization of the acorns is realized by extraction of the tannin through the filtrate after vapor explosion.

Description

technical field [0001] The invention belongs to the field of fermentation alcohol of starchy raw materials, and relates to a method for pretreating acorns by a steam explosion method to realize their comprehensive utilization. Background technique [0002] With the development of the economy and the continuous depletion of petroleum resources, it has become an inevitable trend of current development to use biomass raw materials to produce bioenergy and biochemical products to replace petrochemical products. Using biomass as raw material to produce bioenergy and biochemical products (especially to replace petrochemical products) is a hot topic at home and abroad, and has become the focus of research and development in many countries. As an important part of biomass raw materials, starchy raw materials are increasingly concerned about their utilization. [0003] In my country, starch is used as a raw material for commodities and biotechnology products, and its output ranks se...
