Turbine overflow fermenter

Abstract

The invention discloses a turbine overflow fermenter, the shell of the turbo overflow fermenter is a cylindrical shell, the middle part of the shell is provided with a stirring structure, and the stirring structure includes a stirring Shaft, rotating sleeve, air outlet connecting rod and turbine paddle, the air outlet connecting rod is fixedly installed at the bottom of the stirring shaft, the rotating sleeve is fixedly connected to the stirring shaft directly above the air outlet connecting rod, and the housing The installation height of the fermentation liquid overflow port at the bottom is 10-15cm higher than the top height of the rotating sleeve; the present invention facilitates the selection of the fermentation liquid inside and outside the sleeve through the combination of the air outlet connecting rod, the rotating sleeve and the turbine paddle Convection is formed, through the up and down convection formed by the turbine paddle inside the rotating sleeve, the impact convection in the opposite direction is formed on the top of the liquid surface, which increases the contact area between the fermentation liquid surface and the upper air, and at the same time controls the liquid through the installation position of the fermentation liquid overflow hole. The height of the surface ensures that the formed impact convection can contact the air at the upper end to the maximum extent, which greatly improves the production efficiency.

Description

technical field [0001] The invention relates to the field of microbial fermentation equipment, in particular to a turbo overflow fermenter with high stirring fermentation efficiency. Background technique [0002] Fermentation is a process in which microorganisms use organic matter to decompose and other functions. It is divided into aerobic fermentation and anaerobic fermentation. In the industrial production process, the fermentation process is generally carried out in the fermenter. During the aerobic fermentation process, it is necessary to continuously feed the fermenter Oxygen, while anaerobic fermentation needs to extract the air in the tank or feed inert gas to isolate the air. [0003] In the process of aerobic fermentation in the prior art, various methods are used to introduce oxygen into the fermented liquid in the fermented tank, but because the gas itself continues to float in the fermented liquid due to pressure, the residence time in the fermented liquid It i...

Problems solved by technology

[0003] In the process of aerobic fermentation in the prior art, various methods are used to introduce oxygen into the fermented liquid in the fermented tank, but because the gas itself continues to float in the fermented liquid due to pressure, the residence time in the fermented liquid It is short, so most of the fermentation liquid is in contact with the gas layer on the upper layer of the fermentation tank through stirring to meet the aerobic needs of the microorganisms in the fermentation liquid; it is difficult for the stirring paddle of the ordinary fermentation tank to meet the full contact between the fermentation liquid and the gas However, the stirring paddle with the guide tube only forms convection inside and outside the guide tube, which further improves the contact surface and fails to achieve the purpose of full contact between the fermentation liquid and the air.
