A new type of stirring fermenter

Abstract

The invention relates to a novel stirring type fermenting tank. The novel stirring type fermenting tank comprises a tank body; a motor is arranged on the tank body; the motor drives a stirring main shaft through a belt to rotate; the stirring main shaft is inserted into the tank body; a raw material inlet is further formed in the tank body; a plurality of stirring auxiliary shafts are arranged on the periphery of the stirring main shaft; a foam container is arranged above the stirring auxiliary shafts; a pipe is inserted into the foam container; a foam recovery device is connected to one end of the pipe; a liquid sensor is arranged at the other end of the pipe; a jacket is arranged on the outer side of the tank body; a steam inlet is formed in the lower portion of the jacket; a steam outlet is formed in the upper portion of the jacket; a water outlet for condensate water to flow out is further formed in the lower end of the jacket; the condensate water discharged by the jacket is recovered by the water outlet into a recovery tank through a pipe; and the condensate water in the recovery tank is pumped into the jacket through a pump and a pipe. The novel stirring type fermenting tank is novel in structure and convenient to operate; foams and the condensate water are respectively recovered; and raw material waste caused by overflowing can be avoided.

Description

technical field [0001] The invention belongs to a fermenter, in particular to a novel agitating fermenter which automatically absorbs the foam generated during stirring. Background technique [0002] Mechanical stirring fermenter is one of the commonly used types in fermentation factories. It uses the function of mechanical stirrer to fully mix air and fermentation liquid to promote the dissolution of oxygen, so as to ensure the supply of dissolved oxygen required for microbial growth, reproduction and metabolism. The power required for mixing and interphase mass transfer is input by the stirring turbine. This kind of reactor has the strongest adaptability. From Newtonian fluid to non-Newtonian filamentous bacteria fermentation broth, it can be used according to actual conditions and needs. It provides high mass transfer rate and necessary mixing speed. However, in the process of fermentation and stirring, a lot of foam will appear on the upper end of the liquid. The genera...
