Improved fermentation tank

Abstract

The invention provides an improved fermentation tank. A contact interface of gas and liquid can be increased, so that materials are in full and effective contact, the mass transfer rate between the gas and the liquid is increased, and therefore the fermentation effect and the product quality are improved. The improved fermentation tank comprises a main shaft, an upper end socket, a cylinder and alower end socket, and the upper end socket, the cylinder and the lower end socket are sequentially connected; one end of the main shaft is connected with a motor through a transmission device after penetrating through the upper end socket, and the other end of the main shaft penetrates through the cylinder and is fixed at the bottom of the lower end socket through a bottom bearing; a feed inlet and an air outlet are formed in the top of the upper end socket; an air inlet and a discharging hole are formed in the side wall of the lower part of the cylinder; the main shaft is sequentially sleevedwith a defoaming device and a blade type stirrer below the feed inlet and on the upper portion of the cylinder; the main shaft is sleeved with a multi-roller stirrer in the middle of the cylinder; the main shaft is sleeved with a nine-impeller type rotor on the lower portion of the cylinder.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to an improved fermenter. Background technique [0002] The fermenter is a device used for microbial fermentation, which is widely used in dairy products, beverages, bioengineering, pharmaceuticals, fine chemicals and other industries; the existing fermenter cannot fully and effectively contact the gas-liquid two-phase materials during the fermentation process. The quality rate is low, especially for viscous materials and the fermentation of aerobic microorganisms, the effect is poor, which affects the quality of the product. Contents of the invention [0003] Aiming at the defects of insufficient gas-liquid two-phase contact, low mass transfer rate and poor fermentation effect of existing fermenter materials, which affect product quality, the present invention provides an improved fermenter, which can increase the contact interface of gas and liquid, so that The ...
