干化技术对酒糟生物质资源化利用的影响

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

经济高效的干化技术对于包括农林废弃物、制革废弃物和工业有机固废等生物质的资源化转化利用至关重要。中国白酒产量巨大,为国家经济发展和人民物质需求带来贡献的同时,也产生了大量的废弃酒糟。废弃酒糟具有含水量高、酸度高、易霉变等问题,不易处理,导致其资源化利用一直面临困难。高效、低成本的酒糟干化技术对于其资源化利用具有决定性意义。因此,文章介绍了不同工艺酒糟的特点,详细综述了多种酒糟干化预处理技术与资源化利用技术,以期为酒糟的资源化、能源化转化利用提供借鉴,为酿酒行业在“双碳”背景下的绿色可持续发展和转型升级奠定基础。

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.
