FIELD OF THE INVENTION The invention relates to the microbiological industry, in particular, to the construction of apparatus for cultivating microorganisms.

A device for the cultivation of microorganisms is known, comprising an enclosure, aerators, mixing devices mounted on hollow shafts with drives, and tenon-diverting surfaces 1.

When cultivating microorganisms, in particular, such as Jacquard yeast and yeast-like fungi, on mediums — with a high energy potential of the substrate, for each kilogram of synthesized mass, from 3000 to 6000 kcal of heat is released. With such an amount of heat released, the heat-removing surfaces provided in the prior art apparatus for micro-organizing are ineffective.

The purpose of the invention is to intensify the process of heat removal from the apparatus.

This is ensured by the fact that the hollow shafts of the apparatus are provided with nozzles for filling with fluid boiling at an acceleration temperature, the upper ends of the shafts have fins, and the mixing devices are hollow and connected to the hollows of the shafts. The upper ends of the shafts are separated by a cover from the working space of the apparatus, enclosed in a casing with channels and provided with

impellers to create a directional flow of air.

On the fit. schematically shows the structure of the proposed apparatus, a longitudinal section; in fig. 2 - the same cross section.

The apparatus for cultivating microorganisms comprises a body of 1 second. nozzle 2 for feeding the substrate, nozzle 3 for withdrawing

suspension of microorganisms and choke 4 for the withdrawal of exhaust air. The annarat also contains an aerator 5 and mixing devices 6, which are hollow 11 sockets with hollow cavities

shafts 7, and iridescent for rotation by electric motors 8.

The upper ends of the shafts are separated by a cover 9 from the working space of the device, enclosed in a casing 10 with air channels I and

equipped with ribs 12. At the ends of the shafts fixed impeller 13, providing the washing of the shaft with air.

To ensure the intensification of heat removal to the upper evaporation ends of the shafts, the latter have a ribbed surface (ribs 14). The device works as follows. The source of the substrate through the pipe 2 continuously enters the body 1 of the apparatus, filled with a suspension of microorganisms. The air through the aerator 5 is supplied simultaneously. When the medium is mixed with the aid of device 6, the biomass of microorganisms is continuously synthesized and the suspension is discharged through nozzle 3. Exhausted; into the upper condenser sections of the shafts 7, which are led out of the working space of the apparatus, by the cover 9 under the casing 10. The air is guided in channels 11, and the intensification of heat extraction is provided by the fins 12 and the roof chatkoy 13.

The proposed apparatus has a more compact and simple design, since the mixing device, besides its main function, also performs the function of a heat removal device.

Invention Formula An apparatus for cultivating microorganisms, comprising a housing, aerators, re-mounting devices mounted on hollow sealed drive shafts, and heat-removing surfaces, is distinguished from the fact that, with a purposeful heat removal process, hollow shafts are provided with connections for filling with fluid boiling at the cultivation temperature, the upper ends of the shafts additionally have fins for heat dissipation with air, and the transfer devices are hollow and connected to the hollows of the shafts. 2. The apparatus according to claim 1, differing in that the upper ends of the shafts are separated by a lid from the working space of the apparatus, enclosed in a casing with channels and equipped with an impeller to create a directional air flow.
