Embodiment Construction

[0017] In order to better understand the present invention, the content of the present invention is further clearly described below in conjunction with the examples, but the protection content of the present invention is not limited to the following examples. In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details.

[0018] The expanding culture method of the wine mother in the alcohol production of the present invention, comprises the following steps:

[0019] Step S1, insert the mature distiller's mother in the Karst tank into the small distiller's pot according to the inoculation amount of 0.03~0.05% by volume, pass in sterile air or stir it mechanically, and wait until the distiller's mother in the small distiller's tank is matured, Insert the inoculati...

Abstract

The invention provides an enlarged culture method for a distiller yeast in alcohol production, belonging to the technical field of ethanol production. The enlarged culture method comprises the following steps of inoculating a distiller yeast cultured to be matured in a Carlsberg flask into a small distiller yeast tank, introducing sterile air or stirring by using a machine, inoculating the distiller yeast into a middle distiller yeast tank to culture after the distiller yeast in the small distiller yeast tank is cultured to be matured, and inoculating the distiller yeast into a large distiller yeast tank to culture after the distiller yeast in the middle distiller yeast tank is cultured to be matured; and dividing 4/5 of the matured distiller yeast for inoculation in a fermentation tank and replenishing a fresh distiller yeast saccharification liquor into 1/5 of the rest matured distiller yeast to further culture after the distiller yeast in the large distiller yeast tank is cultured to be matured, and further dividing after the distiller yeast is cultured to be matured, repeating the operation in such a way for n (n>=1) times, and respectively inoculating the matured distiller yeasts divided from the large distiller yeast tank into different fermentation tanks. By using the enlarged culture method for the distiller yeast in alcohol production, resources can be saved, the cost can be reduced, the method is simpler in operation, labor and time can be saved, the quality of the distiller yeast is stable, and the benefit of an ethanol plant is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of ethanol production, and in particular relates to an enlarged cultivation method of distiller's mother in alcohol production. Background technique [0002] Alcoholic fermentation is the process by which yeast converts fermentable sugars into alcohol. Alcoholic yeast belongs to the fungal phylum in taxonomy, Ascomycetes, Atomicycetes, Endospora, Endosporaceae, Saccharomyces, and Saccharomyces. It is an important microorganism in the fermentation industry and can ferment carbohydrates. Substances such as alcohol and carbon dioxide. Yeast is commonly known as distiller's mother in alcohol production, and the expansion and cultivation process of yeast is the preparation process of distiller's mother. The purpose of distiller's expanded culture is to reproduce a large number of yeast cells from a small amount of yeast to supply the yeast seeds needed for fermentation. [0003] Ethanol fermentation is the pro...
