Description
Technical field
The invention belongs to bioengineering subject bioreactor fields, more specifically a kind of to be used for bio-pharmaceuticals, life
The pyknic mechanical stirring energy conservation of materialization work, biological products, bioenergy and the production of food service industry fermented product or cell culture
Fermentor.
Background technique
Fermentor for fermented product production and cell culture is multifarious, on the whole, has aerobic fermentation tank and detests
Aerobe fermentation tank two major classes, and aerobic fermentation tank is divided into mechanical agitating fermentation tank and airlift fermentor, wherein being stirred using machinery
That mixes fermentor accounts for the overwhelming majority.
In order to improve the utilization rate of mechanical stirring aerobic fermentation tank oxygen, most of designers tend to increase ratio of height to diameter,
Air bubble is allowed to stop longer time in liquid, the ratio of height to diameter of mainstay is 3 ︰ 1 at present.It does so, oxygen can improved
Utilization rate in terms of there is no exact evidence, and thus bring negative effect be unquestionable.Firstly, be increase it is logical
Atmidometer, so that the outlet pressure of air compressor machine must be increased, and the effective power consumption of air compressor machine and outlet pressure is square directly proportional.
Secondly, the difficulty of liquid mixing especially axial backmixing is increased, in addition the raising of hydrostatic pressure, so that power of agitator disappears
Consumption is also required to increase accordingly.Third reduces the plot ratio of unit making material, increases fermentor cost of manufacture.
In terms of form of tubes of ventilating, past design preference porous type or more venturi-types are done so, and one is same
Increase the resistance of ventilation, two are not easy to clean, or even generate the dead angle of material stock, form the hidden danger of living contaminants.And for list
Hole ventilation is placed in the snorkel in fermentor and asks there are being entangled with of blowing under blowing on one although reducing aeration resistance
Topic: the stirrer paddle that the air bubble above blown can be largely located at tank bottom is smashed, and is increased liquid-vapor interface product, is conducive to the biography of oxygen
It passs, but be easy to cause solid content in bottom settlings；Under the air bubble that blows avoid the deposition of solid content, but bubble bypasses agitating paddle
Leaf is not broken, influences the transmission efficiency of oxygen.
In addition, due to air outlet slit apart from lower layer's agitating paddle farther out, even on the single hole snorkel that blows, also have suitable one
Partial air bubble cannot be stirred blade and smash.
Summary of the invention
The purpose of the present invention is to provide a kind of aeration resistance is small, plot ratio is high, and the air bubble being passed through can be broken, fermentation
For solid content in liquid not in bottom settlings, gas-liquid mixing is good, simple for structure in tank, to reach the new-type short of energy-saving effect
Fat type energy-saving fermentation pot.
