Embodiment 1

[0021] A kind of method of biological antibacterial molasses alcoholic fermentation of the present embodiment, its process flow chart is as follows figure 1 As shown, the specific steps are as follows:

[0022] (1) In the dilution tank, dilute the molasses to 60Bx, heat the heater to 97°C with steam, flow into the clarification tank, pass through sterile compressed air to stir for 1 hour, let it settle for 1 hour, and remove the sediment at the bottom of the tank.

[0023] (2) Part of the material in step (1) is added with 0.7wt.% of ammonium sulfate, and after the cooler is cooled to 30°C, it is diluted to 11Bx (hereinafter referred to as "dilute sugar solution") through a serial diluter and flows into the seed tank. When the volume of the seed tank reaches 50%, stop feeding, inoculate the seed tank with 0.4wt.% high-activity dry yeast (for molasses fermentation), and continuously feed sterile compressed air to stir and cultivate. When the hammer of the feed liquid in the see...

Embodiment 2

[0026] A kind of method of biological antibacterial molasses alcoholic fermentation of the present embodiment, concrete steps are as follows:

[0027] (1) In the dilution tank, dilute the molasses to 65Bx, heat the heater to 100°C with steam, flow it into the clarification tank, pass through sterile compressed air to stir for 1 hour, let it settle for 1 hour, and remove the sediment at the bottom of the tank.

[0028] (2) Part of the material in step (1) is added with 0.8wt.% of ammonium sulfate, and after the cooler is cooled to 30°C, it is diluted to 12Bx (hereinafter referred to as "dilute sugar solution") through a serial diluter and flows into the seed tank. When the volume of the seed tank reaches 50%, stop feeding, inoculate the seed tank with 0.5wt.% high-activity dry yeast (for molasses fermentation), and continuously feed sterile compressed air into it to stir and cultivate. When the hammer of the feed liquid in the seed tank decreases correspondingly When it reaches...

Embodiment 3

[0031] A kind of method of biological antibacterial molasses alcoholic fermentation of the present embodiment, concrete steps are as follows:

[0032] (1) In the dilution tank, dilute the molasses to 55Bx, heat the heater to 95°C with steam, flow into the clarification tank, pass through sterile compressed air to stir for 1 hour, let it settle for 1 hour, and remove the sediment at the bottom of the tank.

[0033] (2) Part of the material in step (1) is added with 0.6wt.% of ammonium sulfate, and after the cooler is cooled to 30°C, it is diluted to 10Bx (hereinafter referred to as "dilute sugar solution") through a serial diluter and flows into the seed tank. When the seed tank reaches 50% of the volume, stop feeding, inoculate the seed tank with 0.3wt.% high-activity dry yeast (for molasses fermentation), and continuously feed sterile compressed air to stir and cultivate. When the hammer of the feed liquid in the seed tank decreases correspondingly When it reaches 4Bx, the di...

Abstract

The invention belongs to the technical field of biological fermentation,and discloses a method for fermenting biological antibacterial molasses alcohol. Molasses is diluted to 55-65 Bx,heated,sterilized and clarified,then ammonium sulfate is added into a part of materials,the mixture is diluted to 10-12 Bx after cooling and flows into a seed tank,active dry yeast is inoculated for culture,the cellconcentration of the yeast is controlled to be 3 hundred millions / ml or above,the brix of the yeast is 4-6 Bx,and then the mixture constantly flows into a main fermenting tank; the other part of materials are diluted to 46-48 Bx to serve as a fermenting culture solution,the mixture constantly flows into the main fermenting tank,the yeast number in the main fermenting tank is controlled to be 2 hundred millions / ml or above,the corresponding brix is 18-22 Bx,the main fermenting tank is filled with the mixture,then the remaining mixture sequentially flows into follow-up constant fermenting tanksuntil fermenting is mature,and the alcohol is obtained through distilling. In the method,yeast growth advantages are adopted for restraining growth of bacteria,the low-density molasses in the seed tank is adopted for culturing high-density yeast,the alcohol is rapidly and efficiently fermented,the parts of contained liquor are increased,and waste liquor discharging is reduced.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and in particular relates to a method for biological antibacterial molasses alcoholic fermentation. Background technique [0002] Molasses is a by-product of sugar cane or beet sugar factory. Its components include fermentable sugars and nutrients such as sucrose, reducing sugar, amino acids, vitamins and trace elements, as well as inorganic salts such as ash, colloid and caramel. The substances used, in recent years, sugar enterprises tend to adopt strong alkali, high sulfur, high ash and other processes, the content of non-sugar impurities such as ash and colloid in the by-product molasses continues to increase, and it is more difficult to ferment molasses alcohol. The alcoholic fermentation of molasses is relatively extensive, and molasses raw materials and water inevitably carry bacteria. The production of molasses alcohol is mainly through the addition of sulfuric acid to aci...
