Problems solved by technology

[0002] The production of fuel ethanol from sweet sorghum stalks is one of the current domestic research hotspots. At present, the biggest obstacle hindering the industrialization of sweet sorghum is the storage of raw materials. There are currently two storage methods for raw materials of sweet sorghum stalks: one is open-air freezing Storage, such as removing the leaves and bundling the stalks for upright frozen storage, not removing the leaves and setting up a tripod for freezing storage, or bundling and storing them in the field. This method is greatly affected by weather changes. In warm winters and rainy weather, the stalks are prone to mildew It is difficult to guarantee the quality of raw materials; the other is to squeeze the sweet sorghum stalks and add preservatives for storage. In this storage method, the residual preservatives will affect the next alcoholic fermentation. In addition, preservatives volatilize and Emissions cause air and water pollution, requiring innovative storage methods

Embodiment 1

[0024] Embodiment 1: in conjunction with accompanying drawing, do as follows:

[0025] A method for storing sweet sorghum stalk juice, comprising the following processing steps:

[0026] a. Squeeze the sweet sorghum stalks after removing ears and leaves, ultrasonically extract the residual sugar in the stalk dregs, so that the sugar extraction rate is 98%, and mix the extracted juice with the squeezed juice for later use;

[0027] b. Pass the spare juice through a 297μm sieve for coarse filtration to remove the coarse residue, then use a plate and frame filter to separate the sediment and fine residue, and then concentrate the mixed juice to 12BX at 100°C for 30 minutes, Then cool down to 30°C;

[0028] c. Mix active Saccharomyces cerevisiae and cold boiled water at a ratio of 1:10, activate at 35°C for 30 minutes, add 0.1‰ of yeast into the above juice, and then stir evenly; in the pre-fermentation period, the general control The fermentation temperature is 28°C, and the ti...

Embodiment 2

[0031] In conjunction with the accompanying drawings, the following explanations are made:

[0032] A method for storing sweet sorghum stalk juice, comprising the following processing steps:

[0033] a. Squeeze sweet sorghum stalks after ear and leaf removal, wash the stalk dregs with countercurrent water for 6 times, so that the sugar extraction rate is 97%, and mix the washed juice with the squeezed juice for later use;

[0034] b. Pass the spare juice through a 300μm sieve for coarse filtration to remove the coarse residue, then use a butterfly centrifuge to separate the sediment and fine residue, and then concentrate the mixed juice to 15BX at a temperature of 101°C for 30 minutes, then Cool down to 31°C;

[0035] c. Mix active Saccharomyces cerevisiae and cold boiled water at a ratio of 1:12, activate at 35.5°C for 32 minutes, add 0.15‰ of yeast into the above mixed juice, and then stir evenly; the fermentation process is pre-fermented During the fermentation period, th...

Embodiment 3

[0038] In conjunction with the accompanying drawings, the following explanations are made:

[0039] A method for storing sweet sorghum stalk juice, comprising the following processing steps:

[0040] a. Squeeze sweet sorghum stalks after ear and leaf removal, wash the stalk dregs with countercurrent water for 7 times, so that the sugar extraction rate is 97%, mix the washed juice with the squeezed juice for later use;

[0041] b. Pass the spare juice through a 310μm sieve for coarse filtration to remove the coarse residue, then filter it with a disc centrifuge, concentrate the mixed juice to a concentration of 16BX, sterilize it at 102°C for 30 minutes, and then cool it down to 32°C;

[0042] c. Mix active Saccharomyces cerevisiae and cold boiled water at a ratio of 1:15, activate at 36.5°C for 38 minutes, add yeast with an amount of 0.18‰ to the above mixed juice, and then stir evenly; During the fermentation period, the fermentation temperature is generally controlled at 2...

Abstract

The invention relates to a method for storing sweet sorghum stem juice and a storage device thereof. The storage method comprises the following process procedures: (1) active dry yeast for alcohol production is added to water with the temperature of 35-37 DEG C for activation for 30-60min, and the amount of the yeast added to the sweet sorghum stem natural juice is 0.1-0.5 permil; and then the mixture is evenly stirred for fermentation with the period being 24-36h; (2) the fermented juice is hermetically stored at the temperature of 0-35 DEG C. The storage device is a cellar body around whichwalls are provided; a cellar opening with a sealed cover is positioned at the top part of the cellar body, and an air exhaust nozzle is arranged at the cellar opening. Compared with the prior art, the storage method has the advantages of simple operation and practicality; the hermetic storage is carried out by adopting the cellar device, which can prevent oxidation of alcohol and freezing of juice, therefore, the storage method is economical and safe, and can be applied to large-scale storage.
