Large-size efficient liquid fermentation tank

Abstract

The invention discloses a large-size efficient liquid fermentation tank, which comprises a tank body, a sterilization cabin, a reaction cabin and a precipitation cabin, wherein the sterilization cabin, the reaction cabin and the precipitation cabin are all positioned inside the tank body; the sterilization cabin is arranged at the upper end of the reaction cabin; the precipitation cabin is arranged at the lower end of the reaction cabin; one side of the upper end of the tank body is connected with a rotating shaft; the tank body is movably connected with an upper cover through the rotating shaft; an ultraviolet ray sterilization lamp is arranged on the upper end inside the sterilization cabin; a stirring shaft is arranged inside the reaction cabin. The large-size efficient liquid fermentation tank has the advantages that through the graded arrangement of the sterilization cabin, the reaction cabin and the precipitation cabin, fermentation liquid performs layered fermentation reaction from top to bottom; the fermentation reaction efficiency is synchronously improved; in addition, the ultraviolet ray sterilization lamp is arranged on the upper end inside the sterilization cabin; whenbeing required, toxic and harmful microbes in the fermentation liquid can be killed; meanwhile, the upper end of the tank body is movably connected with the upper cover through the rotating shaft; the tank body can be freely opened; the overhaul maintenance on each layered structure inside the tank body is convenient.

Description

technical field [0001] The invention relates to the technical field of fermentation tanks, in particular to a large-scale high-efficiency liquid fermentation tank. Background technique [0002] Fermentation refers to the process in which people use the life activities of microorganisms under aerobic or anaerobic conditions to prepare microbial cells themselves, or direct metabolites or secondary metabolites. Fermentation tanks are industrially used for microbial fermentation. Sterilized by steam, has certain operating flexibility, minimizes internal accessories (avoids dead ends), has strong material and energy transfer performance, and can be adjusted to facilitate cleaning and reduce pollution. It is suitable for the production of various products and reduces energy consumption. Therefore, fermenters are widely used in dairy products, beverages, bioengineering, pharmaceuticals, fine chemicals and other industries. [0003] However, the existing fermentation tanks are not ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a large-scale high-efficiency liquid fermenter to solve the problem that the existing fermenter has a single fermentation operation process and a relatively fixed structure, the liquid reaction rate slows down, the processing time is prolonged, and the fermentation effect is adversely affected. At the same time, its controllable effect is poor during use, and the stability of use needs to be further improved.
