Embodiment 1

[0021] A method for storing crop stalk juice, in which sorghum stalks are used as raw materials in this embodiment, comprising the following process steps:

[0022] 1) Preparation of sorghum stalk juice: After cleaning the harvested sorghum stalks, cut them into 2-5 cm fragments with a kneading machine, add 60-90% of the weight of the stalks to the stalk fragments to soften 15 ~ 30 minutes; after softening, put the raw materials in an industrial crushing device and a grinding device for crushing and grinding, so that the cells are broken up to obtain a stalk slurry; a filter press is used to filter the stalk slurry, The stalk cell slurry is obtained; the stalk juice is obtained after being separated by a centrifuge, and the crushing and grinding process is carried out in a low temperature environment below 20°C.

[0023] 2) Concentrating the sorghum stalk juice prepared in step 1) to a concentration of 15BX-20BX.

[0024] 3) Sterilizing the concentrated sorghum stalk juice at...

Embodiment 2

[0033] A method for storing crop stalk juice, the raw material of this embodiment is sweet sorghum and corn stalk composition, comprising the following process steps:

[0034] 1) Preparation of high-sweet sorghum and corn combined stalk juice: After cleaning the harvested sweet sorghum and corn stalks, cut them into 2-5cm fragments with a crushing machine, and add 60% of their weight to the stalk fragments. ~90% sterile water is softened for 15-30 minutes; after softening, the raw materials are crushed and ground in an industrial crushing device and a grinding device, so that the cells are broken and the stem slurry is obtained; a filter press is used The stalk slurry is press-filtered to obtain the stalk cell slurry; the stalk juice is obtained after being separated by a centrifuge, and the crushing and grinding process is carried out in a low temperature environment below 20°C.

[0035] 2) Concentrating the combined stalk juice prepared in step 1) to a concentration of 15BX-...

Abstract

The invention discloses a storage method of a crop stalk, and belongs to the technical field of storage of industrial raw materials for wine production. The method comprises the steps of: 1) preparation of a crop stalk juice: washing, crushing, softening and milling the raw materials to obtain a stem slurry, and then conducting pressure filtration and centrifugation to obtain a stalk juice; 2) bacterial strain activation and fermentation: activating dry yeast in sterile saline solution, adding the yeast into the stalk juice, and uniformly stirring to carry out a three-stage fermentation; and 3) sealing and storing the fermented juice, and controlling the temperature in the range of 10-15 DEG C. The storage process of the invention is simple and practical; and compared to natural open-air storage of stalks, the method converts sugar into alcohol to minimize loss of sugar in the raw materials during storage, and uses alcohol produced in fermentation and the anaerobic conditions of sealed fermentation tank to prevent the growth of acetic acid bacteria and other bacteria and to ensure the safety of raw materials.

Description

technical field [0001] The invention relates to a method for storing crop stalk juice by fermenting crop stalks to consume sugar and produce alcohol so as to prolong the storage time of the stalk juice, which belongs to the technical field of raw material storage in the wine making industry, in particular to a crop stalk How to store juice. Background technique [0002] With the development of social economy and science, more and more attention has been paid to the development and utilization of crop stalks. The project of producing fuel ethanol from sorghum, sweet sorghum and corn stalks has become a hot research topic at home and abroad. At present, the problems hindering the development of straw-to-alcohol engineering include low raw material quality, high transportation cost, and short storage time of raw materials. The heat generated during the process leads to high nutrient consumption, so that the nutrients in the raw materials are low when they are transported to th...
