This project is the first enterprise in China to realize “harmless, automatic, large-scale and intelligent” in the whole process of yeast culture production from Baijiu distillers’ grains through multi technology integration (including microbial solid fermentation technology, rice husk separation technology, rice husk fuel technology, low-cost seed production technology, etc.). The project was officially completed and put into operation in Gujinggong Industrial Park in 2016, and is operating well. The bio fermented feed produced mainly from ancient distiller’s grains is used for the cultivation of alcohol mother liquor.
Overview
Construction scale and main construction contents of the project: The project plans to use more than 80 mu of land. It needs to build modules such as distiller’s grains pre fermentation workshop, automatic production workshop, finished product warehouse, raw material warehouse, supporting workshop, comprehensive office building, etc., with a construction area of about 20000 square meters. It is necessary to support biological fermentation feed production equipment, build plant roads, greening, water supply and drainage, power transformation and distribution, fire protection, sanitation and other auxiliary facilities, forming an annual processing capacity of 135000 tons of Baijiu distiller’s grains, and produce 50000 tons of biological fermentation feed.
advantage:
The project production basically does not consume water resources, and the fermentation and drying plan uses clean energy natural gas. To reduce energy consumption, the production process adopts multiple energy-saving measures, such as using the heat generated by biological fermentation to remove material moisture; Fermentation and drying equipment adopt strict insulation measures to reduce heat emission; Drying exhaust emissions pass through the waste heat system, recovering heat for use in production processes, etc; The selection of main production equipment complies with relevant national energy-saving technology standards and is equipped with corresponding energy measuring instruments, strictly implementing energy management
Measurement management. ”The operation experience of Gujing Project has proved that this project can make the waste residue of the brewing industry Baijiu distiller’s grains reused. Turning waste into treasure not only solves the worries of the development of Baijiu enterprises, but also creates a new feed resource for the livestock industry. The project construction not only solves the environmental protection problems of enterprises, but also provides a non grain fermented feed for breeding animals, providing another important way to ensure national food security.

| process | Process Description |
| distillers’ grains | For the solid waste residue of the brewing industry, mainly rice husk and grain residue, the moisture content of fresh distiller’s grains is 60-66%, pH3.5-4.0， High acidity, slightly viscous, good permeability |
| preprocessing
|
By naturally stacking and discharging the free water in the distiller’s grains, removing impurities such as metals and stones from the distiller’s grains through equipment, and completing the quantitative feeding and transportation of distiller’s grains |
| Vaccination and nutritional supplementation | The strains and nutrients are put into the ingredient warehouse and quantitatively transported |
| mixing | Using mixing equipment to mix distiller’s grains, bacterial strains, and nutrients in a certain proportion（CV≤25%） |
| Fermentation cultivation | Using brewing yeast as the main strain, in a continuous fermentation equipment, the fermentation conditions are controlled by automatically adjusting the ventilation volume and temperature, allowing microorganisms to grow rapidly and ferment substrates |
| dry | Using a drum or other drying equipment, mixed hot air generated by direct combustion of natural gas is used to quickly remove moisture from the fermentation substrate. The exhaust temperature is above 100 ℃ Celsius to recover waste heat and pre drying water from the material |
| Cooling and impurity removal | Dry materials are transported by conveying equipment to remove small impurities and complete cooling before entering the silo |
| smash | The aperture of the crusher screen is 1.2mm, and the crushing capacity is over 10 tons per hour |
| Packaging and palletizing | 40Kg， Laminated bag (110 * 60cm), folded and labeled, automatic packaging and palletizing, with a capacity of over 300 bags per hour |
| outbound | Automatic palletizing and loading, with a loading capacity of over 600 packages per hour |
