Description

Technical Field

[0001] The invention relates to a plant fiber processing device in an ethanol production process, in particular to a plant fiber softening and conveying device. Background Art

[0002] With the development of society, biochemical industry has developed rapidly in food, animal feed, medicine, various enzyme preparations, ethanol fuel, etc., especially when fossil resources have been gradually exhausted, countries around the world have begun to devote themselves to the research of renewable energy materials. Fuel ethanol, a green new energy that replaces petroleum fuel, has received widespread attention at home and abroad. Because its combustion characteristics are very close to gasoline, it can be mixed with gasoline in a certain proportion, or it can be used directly as fuel, which greatly reduces the emission of harmful gases and has broad development space. Using biomass to produce liquid fuel is one of the trends in the development of renewable energy in the world. The research focus of various countries is on the resource-rich lignocellulose as raw material. The straw fuel alcohol project uses biomass materials such as straw and firewood to convert them into alcohol and a large amount of efficient distiller's grains feed through solid fermentation of straw, and provides clean power resources for automobiles by partially replacing gasoline. It is the direction of "green agriculture" and "ecological agriculture" in the 21st century and is in line with the sustainable development strategy. Straw is a renewable natural energy resource that will not harm the environment. It is a "natural resource that can be used reasonably and sustainably". It can not only alleviate the shortage of commodity energy, but also be conducive to the comprehensive promotion of agricultural science and technology and the comprehensive utilization of renewable materials, and play a positive role in the sustainable development of rural economy and the protection of ecological environment.
