A rice wine pressing device and method

Abstract

The invention discloses a device and method for squeezing rice wine.The device comprises a differential pressure extraction separator, an extraction feeding buffer tank and a ceramic microfiltration membrane filter.A high speed flow is formed by high-pressure difference in instantaneous time through vacuum-pressurization-vacuum cyclic changes, the wine body in distilled grain is in full contact with a solvent (mellow rice wine) and is dissolved, so that wine in win residue is extracted; after solid-liquid separation, physical separation is performed through the ceramic microfiltration membrane filter, and the whole squeezing process is accompanied with a sterilization and turbidity removal process, so that the rice wine brewing process is integrated better.

Description

technical field [0001] The invention relates to a rice wine pressing device, in particular to a rice wine pressing device and method. Background technique [0002] Yellow rice wine is a traditional brewed wine in China. It is more and more favored by consumers because of its rich amino acids, organic acids, and sugars, and its unique taste. After a long period of low-temperature fermentation, rice wine is fermented with distiller's grains and liquor, and it needs to be pressed after fermentation. Therefore, the process of pressing rice wine largely determines the quality of rice wine. It is of great significance to study and explore the filter press technology of rice wine production in my country and promote the development of rice wine industry in my country. [0003] During the brewing process of rice wine, after fermentation, the wine and the lees are mixed together, and the density of the solid part and the liquid part are close to each other, forming a sticky paste. ...

AI Technical Summary

Problems solved by technology

However, the feeding port of the filter frame is easy to block, the filter cake is not easy to take out, it cannot run continuously, the processing capacity is small, the working pressure is low, the square plate of ordinary material is not pressure-resistant, easy to break the plate, the consumption of filter cloth is large, and the plate frame is difficult to do. Unattended, the filter cloth often needs to be cleaned manually, the pressing rate is not high enough, the transparency of the wine body is not high, etc.
