Problems solved by technology

Although this method also has a certain effect, it is often used as a heat source for the drying of distiller's grains for the rice husks that contain a lot of distiller's grains.
Generally speaking, the value-added range of distiller's grains is not large in the above-mentioned utilization methods, and these technologies are often single, only paying attention to the development of a certain product. In fact, only by effectively realizing high-value components of distiller's grains It is possible to completely solve the problem of the resource and its abundant distiller's grains

Abstract

The invention discloses a poly-generation utilizing technological system for the ester extraction, the fermentation and the classification of white spirit vinasse, which gets rid of the traditional thought of utilizing a certain component of the vinasse or the whole vinasse as fuel and a feed, and transforms the vinasse into products with high additional value, such as a bouquet matter, alcohol, a protein feed, a raw material for making building materials, and the like. The method comprises the following basic steps of: firstly extracting the volatile matters in the vinasse, replacing the cooking with high pressure and long time by steam explosion with low pressure and short time, directly carrying out solid-state fermentation on the treated residual starch to generate alcohol, extractingthe alcohol generated by the fermentation by using the cyclic gas stripping of carbon dioxide during the fermentation, mechanically classifying the fermented materials by a special apparatus, separating a part which is rich in protein and starch from a rice hull part, carrying out direct or aerobic solid-state fermentation on the separated high-protein part to further increase the protein content, drying and crushing the high-protein part to be used as a high-protein feed, and using the separated rice hull part as the raw material of building materials directly or after drying treatment.

Description

technical field [0001] The invention relates to a comprehensive utilization method of liquor production by-products, in particular to a liquor lees extraction-fermentation-graded polygeneration utilization method. Background technique [0002] Liquor is a traditional beverage in my country, and its brewing history has been in thousands of years. Along with the industrialization of liquor production, the amount of its by-products is also increasing day by day. my country's annual production of liquor is about 27 million tons, and the distiller's grains produced are more than 65 million tons, which is large and concentrated. Because it is acidic, it is easy to go moldy. If it is not treated in time, it will cause serious pollution. However, due to various reasons such as incomplete fermentation, distiller's grains still have certain nutritional value and utilization. In addition, the distiller's grains, yellow water and bottom pot water of liquor production contain a large a...
