Description

Circulating alcohol extraction system

Technical Field

The invention belongs to the field of brewing equipment, and particularly relates to a circulating alcohol extraction system.

Background

The production of Chinese liquor mainly adopts the solid fermented grain fermentation and solid distillation method. Filling the fermented grains into a retort barrel of a distiller, generating water vapor from the bottom of the retort barrel, and distilling to extract alcohol components and flavor components in the fermented grains. During the distillation process, due to the heat exchange effect and the pushing effect of the water vapor at the bottom, alcohol components and flavor components in the fermented grains are gradually enriched to form alcohol vapor, the alcohol vapor ascends from the bottom of the retort barrel to the top of the retort barrel layer by layer, the alcohol components are continuously concentrated, and meanwhile, a large amount of alcohol-soluble flavor components in the fermented grains are continuously extracted along with the continuous concentration of the alcohol components. Therefore, the extraction efficiency of the flavor components in the fermented grains on the upper part of the steaming bucket is higher than that of the fermented grains on the lower part of the steaming bucket, and the extraction is more complete. The ideal distillation process is that the alcohol component is concentrated layer by layer in the retort barrel and is uniform, thereby achieving the maximum efficiency of extracting and enriching the flavor component in the fermented grains. However, in actual operation, due to the large volume in the retort barrel, the loose structure of the solid fermented grains is not uniform, the local density is not uniform, the direction and power of the water vapor or the wine vapor going from bottom to top are not stable, and meanwhile, due to human operation factors, the fermented grains are easy to press the vapor too deeply, i.e., the water vapor or the wine vapor is located deep below the surface of the fermented grains, so that the uniform diffusion and rising effects of the water vapor or the wine vapor are affected, the various conditions are easy to cause the phenomena of nonuniform vapor passing in the retort barrel, unstable power of vapor passing and too fast or too slow local vapor passing, so that the ideal states of uniformly enriching and aroma-extracting alcohol components layer by layer are destroyed, the problems of low alcohol content, low aroma-extracting efficiency, large flavor component impurity in the wine and the like are caused, and the yield and quality of the wine are seriously affected.

Some technical solutions of alcohol distillation also appear in the prior art, for example, a chinese patent with application number 201210244607.5 discloses a device for extracting bouquet by multi-stage distillation, which comprises a first-stage distiller, a second-stage distiller and a cooler connected with each other, wherein each stage of distiller is connected with the cooler through a wine steam delivery pipe. The method for extracting bouquet by adopting the device comprises the steps of inputting steam to the bottom of a primary distiller to distill the fermented grains, enabling obtained wine steam to enter a secondary distiller from the bottom in sequence to continue distilling the fermented grains, outputting obtained wine steam which is further enriched and refined from the top, enabling the wine steam to enter the next secondary distiller from the bottom again, and repeating the steps until the enriched and refined wine steam is collected in a cooler to become wine liquid. Although the technical scheme can realize the distillation of the fermented grains in the rectifier, the technical scheme cannot fully distill the fermented grains; meanwhile, the technical scheme can not utilize distilled alcohol vapor to circularly distill a single distiller, so that the alcohol distillation efficiency in the primary distiller, the secondary distiller and the third distiller is inconsistent, the alcohol output efficiency of fermented grains is reduced, and simultaneously the technical scheme can not collect the alcohol vapor quickly; so that the use of the invention is limited.
