Impact of Drying Technology on Biomass Resource Utilization of Distillers' Grains

Efficient and cost-effective drying technology is critical to the value-added utilization of agricultural and forestry waste, tannery waste, and industrial organic solid waste. The huge production of Chinese Baijiu not only contributes to the economic development of the country, but also produces a large amount of waste distillers' grains. The resource utilization of distillers' grains is limited due to its high moisture content and acidity. It is also easy to mildew, which is hard to deal with. The efficient and low-cost distillers' grains drying technology is of decisive significance for its resource utilization. Therefore, the character of distillers' grains produced by various fermentation processes was introduced in this work, and the drying and utilization technologies of distillers' grains were also reviewed, which helps the resource utilization and energetic conversion of distillers' grains. It also lays a foundation for the sustainable development and green transformation of Baijiu industry.
