Description

брасываетс через кольцевой зазор между нижней и верхней тарелками 4.is thrown through the annular gap between the lower and upper plates 4.

Газ засасываетс через полый вал и через радиальные трубки, расположенные над и под турбинкой 3, подаетс на лопасти 5-7, где диспергируетс и аэрорирует культуральную жидкость.Gas is sucked through the hollow shaft and through the radial tubes located above and below the impeller 3, is fed to the blades 5-7, where the culture fluid is dispersed and aerated.

Образующа с в результате выращивани микроорганизмов пена разрушаетс диском 14. Через отверсти 15 на валу осуществл етс рециркул ци аэрирующего газа. Подача свежих порций питательной среды, отбор, поступление газа в аппарат и его отбор производитс через соответствующие патрубки. Поддержание оптимальной температуры осуществл етс при помощи термостатирующей рубашки. Параметры процесса ферментации контролируютс соответствующими датчиками и термометрами.The foam produced as a result of the growth of microorganisms is destroyed by the disk 14. Through the holes 15 on the shaft, the aerating gas is recirculated. Supply of fresh portions of the nutrient medium, the selection, the flow of gas into the apparatus and its selection is carried out through the corresponding nozzles. The optimum temperature is maintained with a thermostatic jacket. The parameters of the fermentation process are monitored by appropriate sensors and thermometers.

Claims

1. An apparatus for growing microorganisms containing a cylindrical container with

a jacket, a concentrically mounted hollow shaft with a densely fortified aerating and mixing devices in the form of a closed turbine and an antifoam agent located in the upper part of the tank, characterized in that, in order to intensify the process of growing microorganisms, the turbine is enclosed in conical plates installed with a gap along the periphery, and its blades are arranged in concentric rows and

have the form of a trapezoid, and on the hollow shaft there are radially fixed tubes for the supply of air, located above and below the impeller.

2. The apparatus according to claim 1, characterized in that, in order to reduce the wear of the plates, the latter are made of a hydrophobic material.
