Problems solved by technology

The currently reported methods of treating rice distiller's grains mainly include making fragrant grains, vinegar, and soy sauce, or using them for one-time distillation of liquor and extracting alcohol, and then treating them as waste, or even selling them cheaply as chicken and duck feed, and plant fertilizers. However, these methods Not only failed to form industrialization, but also failed to maximize the utilization rate of rice distiller's grains, and the added value of the application was low. Although some of these technologies used rice distiller's grains for secondary brewing, the utilization rate of the obtained distiller's grains was extremely low, and most of the nutrients Substances have not been effectively developed and utilized

Abstract

The invention discloses a closed-cycle circular yellow wine brewing method by squeezing yellow wine lees, and belongs to the technical field of yellow wind brewing. The method comprises the following steps: extruding the yellow wine lees after adding enzyme or not, mixing with yellow wine raw materials subjected to cooking pre-treatment of the traditional yellow wine brewing process, and then fermenting, wherein the obtained yellow wine lees as the secondary raw material are recycled according to the steps so as to form a well-behaved closed-cycle circular process. According to the method disclosed by the invention, the utilization rate and the liquor yield of the yellow wine lees are increased, the prepared yellow wine is unique in refreshing taste and rich in nutrient, and the high-valued recycling of the lees waste is realized.

Description

technical field [0001] The invention relates to a closed-circuit circulation type rice wine brewing process for processing rice wine grains by using an extrusion technology, and belongs to the technical field of rice wine brewing. Background technique [0002] Yellow rice wine is the oldest kind of wine in my country. Together with beer and wine, it is called the world's three major ancient wines. It is the treasure of Chinese wine and is known as the "national wine". It has the characteristics of rich aroma, sweet wine body, unique flavor and rich nutrition, and is a kind of low-alcohol wine that people like. Rice distiller's grains are the by-products of rice wine production, that is, the residues of raw materials after saccharification, fermentation, and press filtration. They are rich in starch (20% to 30%), protein (above 20%), amino acids, cellulose and some Trace elements have extremely high utilization value. In addition, wet yellow distiller's grains are suitable ...
