Rice wine filtering process method

Abstract

A disc-type diatomite filter is adopted in the rice wine filtering process method, an inlet of the disc-type diatomite filter is connected with an outlet of a mixing and stirring tank, a rotatable filtering disc is installed in the disc-type diatomite filter and connected with a motor driving the filtering disc to rotate, and an air inlet pipe is connected to the middle of the disc-type diatomite filter. Comprising the following steps of (1) stirring and mixing, (2) first-time precoating, (3) second-time precoating, (4) sampling and (5) filtering, produced rice wine meets the national standard, and the whole filtering time is shortened by 1 / 3-1 / 4 due to the fact that the phenomenon that a filtering rod is blocked is reduced while the rice wine is detected to be qualified, and the filtering efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of condiment processing, in particular to a rice wine filtration process. Background technique [0002] Rice wine is a kind of drink liked by the people. Its alcohol content is low. After adding water to the existing rice wine liquor, it will appear white turbidity and loss of light when the temperature is lowered. After research, this phenomenon is caused by the dissolution of higher fatty acid ethyl ester in liquor. At present, activated carbon is used to adsorb and remove higher fatty acid ethyl esters from the wine liquor, and the clarified wine liquor is obtained by filtering with diatomaceous earth; the existing treatment method not only consumes a lot of energy, but also forms a large amount of waste activated carbon and diatomite. Moreover, activated carbon and diatomaceous earth cause waste of resources and pollute the environment. [0003] Therefore those skilled in the art devote themselves to de...
