White vinegar production equipment and white vinegar production process

Abstract

The invention relates to white vinegar production equipment. The white vinegar production equipment comprises a fermentation tank, a material pumping device and an oxygen supply device, wherein the material pumping device comprises a material pump, a feeding pipe and a discharging pipe, two ends of the feeding pipe respectively communicate with a feeding hole of the material pump and the fermentation tank, and two ends of the discharge pipe respectively communicate with a discharge hole of the material pump and the fermentation tank; and the oxygen supply device comprises an air pump and an air inlet pipe, and the two ends of the air inlet pipe communicate with the air pump and the discharging pipe correspondingly. When raw materials circulate in the fermentation tank, the feeding pipe and the discharging pipe, the raw materials can be mixed with air, so that the mixing uniformity of the raw materials and the air is effectively improved, and the fermentation quality of the raw materials is ensured.

Description

technical field [0001] The application relates to the technical field of white vinegar production technology, in particular to a white vinegar production equipment and a white vinegar process. Background technique [0002] At present, the manufacturing process of white vinegar mainly includes: batching, fermentation, filtration, decolorization, storage, compounding, sterilization, and filling. The process that determines the quality of white vinegar is the fermentation process. The fermentation process mainly includes: raw material grinding, pulping, liquefaction, saccharification, alcoholic fermentation, acetic acid fermentation. When fermenting alcohol into vinegar, acetic acid bacteria are used. The acetic acid bacteria are aerobic bacteria, so it is necessary to ensure sufficient oxygen during the fermentation of the acetic acid bacteria. [0003] For this reason, a mixer is usually arranged on the fermenter, and the contact of the acetic acid bacteria with oxygen is ...

AI Technical Summary

Problems solved by technology

However, limited by the efficiency of stirring, the method of ensuring sufficient oxygen supply by stirring is only suitable for fermenters with small capacity.

For a large-capacity fermenter, on the one hand, it is impossible to ensure the adequacy of stirring in a short period of time, and it is difficult to ensure better fermentation quality; on the other hand, the volume and power of the mixer used in the large-capacity fermenter The volume and power of the mixer on the small-capacity fermentation tank will be greatly increased, thereby greatly increasing the manufacturing cost of the large-capacity mixing tank, which is not conducive to the production of the fermentation tank
