Abstract

The invention relates to a purification process for super-mature vinegar. The purification process comprises the following steps: firstly, performing coarse filtration on the mature vinegar; secondly, performing oscillation gathering treatment, sterilization and aging treatment on the vinegar subjected to the coarse filtration for the first time; thirdly, performing oscillation gathering treatment and sterilization treatment for the second time, wherein a most key step is the oscillation gathering treatment, and a treatment mode is that voltage of not lower than 3,000 V is adopted for carrying out discharge on positive and negative electrode plates, and negative and positive ions generated by the positive and negative electrode plates in electrode space are utilized to adsorb sediments and microorganisms in the vinegar; in addition, oscillators connected to the positive and negative electrode plates are utilized to remove the sediments adhered to the positive and negative electrode plates and enable the sediments to drop into a sediment collecting tray, and the sediments are discharged through a residue discharge pipeline and a residue discharge hole. The process effectively solves serious turbidity and precipitation problems ubiquitous in super-mature vinegar and a problem of over-standard of mixed strains caused by easy microorganism propagation of the super-mature vinegar in the prior art.

Description

Technical field [0001] The invention relates to a purification process and a purification device for aged vinegar, belonging to the technical field of vinegar production. Background technique [0002] Aged vinegar is a traditional seasoning of the Han nationality, with a long history and culture, and the regional history is very distinctive. Shanxi old aged vinegar is a model of the regional history of aged vinegar. Fermentation of solid grains to brew vinegar is one of its characteristics. [0003] Shanxi old vinegar is brewed with grains as the main body, through the stages of microbial koji making, saccharification, alcohol fermentation, and acetic acid fermentation. Among them, common starchy raw materials for brewing vinegar include millet, sorghum, glutinous rice, barley, wheat, and soybeans. [0004] When vinegar is brewed, taste is a very important indicator of vinegar identification, and there are many factors that restrict taste, including any one-step process parameter c...
