Method for accelerating aging of baijiu and device thereof

Abstract

The invention provides a method for accelerating aging of baijiu and a device thereof. The process of natural aging of baijiu is simulated, an environment of gas-liquid front atomization, oxidizing gas reverse convection and micromixing and efficient mass transferring of gas (oxidizing gas), liquid (newly produced liquor) and solid (ceramic material) being achieved in an aging machine is established, and the transforming behavior of micro constituents in the liquor body is effectively promoted in the natural aging process. In the whole aging accelerating process, no substances generated in thenon-fermentation process is added, no style and feature of any flavor type pure grain brewing baijiu is changed, and meanwhile, the method is low in cost and easy and convenient to operate, and suitable for industrialized production of any type of flavor baijiu in different scales. The color, the flavor and the taste of the treated baijiu are the similar to the baijiu naturally aged for two yearsor above.

Description

technical field [0001] The invention belongs to the field of liquor aging, and in particular relates to a method and a device for accelerating the aging of liquor. Background technique [0002] Newly brewed liquor is spicy and irritating, and has a new wine odor mainly composed of volatile sulfides, methanol, free ammonia and other low-boiling substances produced by the degradation of sulfur-containing proteins during the fermentation process. Naturally stored for several years, the low boiling point substances in the wine body are volatilized, and various reactions in the wine body are gradually balanced, so as to eliminate the smell of new wine and increase the sense of aging. This process is called aging (also called aging or aging). However, in the natural storage process, a large amount of funds must be backlogged and equipment investment must be increased. At the same time, 2 to 3% of the wine will be lost every year, causing huge economic losses to the company. It ha...

Problems solved by technology

Patent CN 101250474A proposes to make wine liquor multi-stage atomized in a high-gravity rotating bed filled with ceramic fillers, and cross-flow with oxidizing gas, so as to realize the ) microscopic mixing and high-efficiency mass transfer process, which effectively promotes the aging behavior of liquor; but its relatively complex equipment and high energy consumption limit its popularization and application; patent CN 201553724U has developed a kind of intermittent treatment of liquor Advanced aging equipment, in order to fully mix the gas, liquid and solid, and effectively promote the aging reaction, it needs to be repeatedly treated

Although this method has a certain effect, it ignores that volatilization is also one of the important behaviors of liquor aging, and it cannot be produced continuously, which limits large-scale industrial production; into the air; the patent CN203283659U designed a wine storage tank with a built-in annular ceramic tube, and the inner cavity of the ceramic tube communicated with the atmosphere

These methods all have certain effects, but the time required for aging is long and the efficiency is low, which limits their popularization and application.
