Description

Technical Field

[0001] The present invention relates to the technical field of microbial fermentation, and in particular to a fermentation device, a fermentation method and an intelligent fermentation process. Background Art

[0002] Microbial fermentation is a biochemical process in which microorganisms (mainly bacteria, yeast or mold) metabolize under specific conditions (break down organic matter into smaller molecules through the action of enzymes and produce energy) to produce useful products or achieve specific purposes. This process is usually accompanied by the formation of gases (such as carbon dioxide or hydrogen) and various organic metabolites, such as alcohol, lactic acid, acetic acid, etc.; the fermentation efficiency is affected by the genetic characteristics of the strain and the culture conditions, and is widely used in the fields of food, medicine, etc.; the application of microbial fermentation technology in the food field is extensive and far-reaching, especially in the production of various types of fermented foods.

[0003] Among them, the biological fermentation device is the most commonly used basic equipment in microbial fermentation. It is widely used in the production of various fermented foods, especially in beverages containing fermented products (yogurt, apple vinegar), sauces (soy sauce) and cheese and other foods. In the existing biological fermentation devices, such as Chinese patent CN113186056B, a solid-state fermentation device and a solid-state fermentation method are disclosed. Through the structural design of the solid-state fermentation device, the production method of the traditional pit mud cellar is changed, so that the upper and lower mash in the fermentation tank are in a relatively consistent environmental condition, so that the fermentation quality of the upper and lower mash is kept consistent. Through the staged control of the tank body insulation, it is beneficial to keep the cellar mud in a suitable fermentation temperature stage, reduce the impact of the external environment on the microbial fermentation process in the cellar mud, promote fermentation, regulate the uniformity and consistency of fermentation, and promote the stability of fermentation quality.

[0004] However, in the existing biological fermentation devices, most of them adopt the process flow of fermentation after filling, and in the actual fermentation process, it is necessary to regularly turn the inside of the fermentation device to disperse the raw materials densely filled due to gravity. The existing dispersion mostly adopts the stirring method of a stirrer, and the existing stirrer can only stir and disperse the raw materials in the same layer, but it is difficult to stir the raw materials between the upper and lower layers.
