Axial center aeration and jet-booster type stirring fermenter

Abstract

The invention is to ventilate compressed air into fermentation tank through stirring axial core, and open cell on blade or ventilate air to short pipe cooperated with position and way of paddle, the air outlet is near to paddle to reach maximum diintegration degree, and mix instantly with liquid. The invention overcomes the shortcomings of relative long route of air in other ventilating way, direct rising of bubble to liquid upper side without passing through stirring area, and low avalability rate of air (oxygen), and reduces energy consumption, such as time, stirring power and ventilating amount. The counteracting force of air injector boosts the sitirring and favourable for increasing stirring efficiency and saving energy.

Description

technical field

[0001] Fermentation equipment in chemical, pharmaceutical, biological, food and light industries. Background technique

[0002] The 21st century is a century led by bioengineering technology, and fermentation is the basis of biotechnology industrialization. The macroscopic kinetics of biological reactions is the basis of fermentation process optimization, and the bioreactor is the external environment of the fermentation process, which also affects the efficiency and optimization of the fermentation process.

[0003] Ventilation and stirring fermentation equipment is widely used in fermentation equipment, but no matter what the ventilation method is, the air enters the interior of the equipment through a separate pipe from the outside for ventilation through a distributor. The invention is a device for fully breaking up the gas and fully mixing the gas and liquid by changing the ventilation mode, so as to increase the dissolved oxygen rate and reduce energy ...
