Embodiment 1

[0060] This embodiment illustrates the preparation method of the distiller's grain suspension and the separation and recovery method of the complete rice husk of the present invention, see figure 1 shown.

[0061] Some process parameters for the establishment and separation of distiller's grain suspension were determined through single factor experiments: when the mass ratio of solid to liquid is 1:2, the soaking time is 30 minutes, the number of washings is 6 times, the aperture of the sieve is 1mm, and the centrifugal speed is 3000r / min, and the centrifugation time is 15min, the establishment and separation process of distiller's grain suspension can be completed.

[0062] The separated rice husks and fresh rice husks were compared and analyzed under a microscope, and it was found that the recycled rice husks were darker in color, while the fresh rice husks were golden yellow and brighter in color. However, the structure of the recovered rice husk is still relatively comp...

Embodiment 2

[0069] This example illustrates the application of recycled rice husks in liquor fermentation.

[0070] After mixing the recovered rice husk and fresh rice husk evenly according to the mass ratio of 1:1, they are re-added to the fermentation process of liquor to produce liquor; half of the fermentation raw materials come from recycled rice husk, other raw materials and The conditions of the fermentation process are all the same as the original liquor fermentation conditions.

[0071] Due to the variety, quality and starch content of wine-making raw materials, it has a great influence on the stability and comparability of wine yield. Therefore, the alcohol yield of raw grain cannot be used as the basis for assessment, but the alcohol yield of standard raw grain should be assessed. The specific requirements and practices are as follows:

[0072] (1) Standard raw grains: raw grains, mainly including grains for brewing wine, yeast grains and residual starch in Daqu (excluding br...

Embodiment 3

[0085] This example illustrates the method of recycling rice husks to produce bran yeast.

[0086] Wheat bran: rice husk = 95:5 (mass ratio) for the production of bran koji. The production method is: 3 kinds of bacteria are required for the bran koji, namely Hanoi white koji, Bacillus subtilis, and lipogenic yeast (all purchased from ATCC ), which were cultured with single strains and finally made into bran koji and mixed in a certain proportion for use. A. Hanoi white koji: Selected combination medium: add water at a ratio of 1:1, stir evenly, autoclave at 121°C for 1 hour, cool to 35°C, add seed koji at 2%, mix evenly, Keep the room ventilated, the humidity is 95%-100%, the culture temperature is 35°C, and the culture time is about 72 hours. B. Bacterial gluten koji: After fermentation, it can produce the characteristic aroma of typical sesame-flavored liquor. Add water according to the ratio of selected combination medium: water = 1:1, autoclave at 121°C and cool to 37°C,...

Abstract

The invention relates to a method for recycling vinasse, and belongs to the technical field of resource recovery. The vinasse is washed by water and is soaked in the water to be changed into vinasse suspension liquid in which rice hulls and elution precipitates are suspended; the vinasse suspension liquid is subjected to screening and filtration to obtain the integral rice hulls; after the recycled rice hulls and fresh rice hulls are mixed together uniformly according to the mass rate of 1:1, and the mixture is added during a white spirit fermentation process again to produce white spirit; or mouldy bran is produced according to the mass ratio of mouldy bran to rice hulls being 95:5; filtrate which is obtained after screening and filtration is centrifuged or precipitated, and the obtained precipitate is used for preparing an animal feed; and filtrate which is obtained after screening and filtration is centrifuged or precipitated, and the obtained supernatant is recycled to be used as the water for washing the vinasse of step (1). Compared with various vinasse recycling methods of the prior art, the method has high vinasse utilization value, the liquor can recycle all the components of the treated vinasse most effectively, and the method has a good recycling effect.

Description

technical field [0001] The invention relates to a recovery and reuse method of distiller's grains, belonging to the technical field of resource recovery. Background technique [0002] The distiller's grains are the mixed solids left after distilling the wine after fermenting the distiller's grains. Therefore, there are still quite a lot of unused protein, starch, fat and other components in the distiller's grains, which are similar to the nutrients in the distiller's grains, only in quantity There is a difference. In addition, due to various complex biochemical changes in the whole fermentation and brewing process, quite a lot of new components have also been produced, such as ribonucleic acid, purine, pyrimidine and other secondary metabolites, which are beneficial to the growth of microorganisms. Trace components, which greatly enhance the utilization value of distiller's grains. [0003] In recent years, with the development of my country's liquor technology and the pr...
