Supplementing type table vinegar shallow layer solid state fermentation device and fermentation method thereof

Abstract

The invention belongs to the field of bioengineering equipment, and relates to a back-supplement type table vinegar shallow solid state fermentation device and a fermentation method thereof, the back-supplement type table vinegar shallow solid state fermentation device comprises a feed hopper, a discharge hopper, a conveyor belt, a conveyor belt support, a gear motor, a feed liquid tank, a reflux pump, a reflux pipeline, a feed liquid nozzle, a fermentation box body, an air supply device and a temperature measuring device. The conveyor belt is provided with multiple layers and is used for carrying materials, the upper-layer materials naturally fall onto the lower-layer conveyor belt during starting and are conveyed layer by layer, and fermented grain layers are formed on the surfaces of the conveyor belts; the raw material wine mash is stored in the feed liquid tank, pumped and sprayed to the uppermost layer of material through the reflux pump, the reflux pipeline and the feed liquid spray head, naturally permeates and passes through each fermented grain layer and then is collected, and then is circularly supplemented and sprayed to the uppermost layer of vinegar fermented grains, so that the back-supplementing type shallow fermentation of the table vinegar is realized. The back-supplementing type table vinegar shallow-layer solid-state fermentation device is small in occupied area and easy to operate, the production efficiency and the product quality of table vinegar can be remarkably improved, the labor intensity is reduced, and huge economic benefits and social benefits are achieved.

Description

Technical field [0001] The present invention belongs to the field of biotechnological equipment, specifically relates to a kind of replenishment type vinegar shallow solid fermentation device and fermentation method thereof. Background [0002] Vinegar, or vinegar for short, is a seasoning and food that contains acetic acid. The unique process of Chinese vinegar brewing is solid acetic acid fermentation. Nowadays, the four famous vinegars in China are brewed using solid state technology. Vinegar solid brewing is mainly a mixture of bacteria for collaborative fermentation, the acetic mash and other mash into acetic acid, other organic acids and flavor substances, together to give solid fermented vinegar a unique taste and good quality. [0003] The fermentation container used in the vinegar solid acetic acid fermentation process is generally a stainless steel tank, a large cylinder (urn) or a cement pool with acid-resistant tiles, and the starchy raw materials to be fermented are ...
