Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of liquor fermentation, especially to a culture device for Hansenula in discarded bran of Maotai-flavor liquor. BACKGROUND

[0002] Discarded bran of liquor is a by-product after raw materials are fermented for a long time. Therefore, discarded bran of liquor has a large amount of bacterial debris, and is richer in complex growth factors and metabolic products. Discarded bran of liquor contains about 15% of protein, 21% of crude fiber, 6% of fat or lipids, and a variety of vitamins and more than ten kinds of amino acids and other beneficial components in terms of dry matter. In view of the rich material composition and low cost of discarded bran of liquor, a large amount of work has been carried out on the recycling and recovery of discarded bran of liquor. For example, discarded bran of liquor is used to produce edible fungi, feed, biogas, alcohol, fertilizer, and high-value-added products (such as coarse enzyme preparation) and single-cell protein feed (mainly yeast).

[0003] Chinese invention patent (invention publication number: CN113180149A name: a method for continuously fermenting and producing probiotic feed using discarded bran of liquor as raw material) makes full use of the by-products produced during the brewing of yellow rice wine. First, the good-nurturing probiotic bacteria and anaerobic probiotic bacteria are separately and individually used for continuous fermentation, and then mixed fermentation. The good-nurturing probiotic bacteria and anaerobic probiotic bacteria coordinate with each other: the anaerobic bacteria use the amylase produced by the aerobic bacteria to hydrolyze the starch in the discarded bran of liquor that has not been completely utilized into small molecule sugars to produce organic acids that inhibit the growth of harmful microorganisms, and the aerobic probiotic bacteria can consume oxygen in the environment to facilitate the growth of anaerobic microorganisms and inhibit the growth of other good sample bacteria. Through continuous operation, stable quality fermented feed can be produced, the operation is simple, the production efficiency is high, and it is suitable for large-scale production. However, the treatment of discarded bran of liquor at the feeding inlet of the device is too simple, which affects the fermentation production efficiency of discarded bran of liquor.
