Description

one

The invention relates to the microbiological industry and can be used to produce biomass of yeast and other microorganisms.

A known apparatus for growing microorganisms comprising a cylindrical container, a circulation cylinder equipped with an annular air manifold located at the bottom, and a turbine aerator located in an annular chamber formed by an air collector and the bottom of the Cl.

The known design of the apparatus is not sufficiently effective in removing heat generated during the vital activity of microorganisms and does not ensure the thermostabilization of the process of growing microorganisms, since the apparatus performs convective heat exchange by pumping cooling water without phase transitions. Closest to the proposed apparatus for the extraction of micro-erganisms, containing a container, an aerator and a heat exchange device of the type

a tube with a collector ohm condensate located above the proposed culture liquid level and placed in a cooled jacket 2j.

The disadvantage of the known apparatus is low productivity, because of the insufficiently intensive heating process.

The purpose of the invention is to increase productivity by speeding up the heat pump process.

Claims (2)

The goal is achieved by the fact that in the apparatus for growing microorganisms containing a tank, an aerator and a heat exchange device of the heat pipe type with a collector-condenser located above the proposed culture liquid level and placed in a cooled jacket, a section of heat pipe located in the culture liquid is made in the form of two cylindrical shells of shells, placed one in another with the formation of an annular gas flow rate for the refrigerant, with the upper part of the shells communicating with the collector condenser ron noqjeflcTBOM tubes. FIG. 1 shows an apparatus for growing microorganisms, vertical paspeaj. in fig. 2 shows section A-A in FIG. one; in fig. 3 - section bb in fig. 1. Microorganism growing apparatus. It contains a vertical tank 1, an aerator in the form of a turbine wheel 2 fixed to the drive shaft with a suction pipe 3, communicated through the air manifold 4 to the air duct 5. The turbine wheel 2 is located in an annular chamber 6 formed by the air collector 4 with the bottom of tank 1 The annular chamber b has ducts 7 for circulating cultured LIH1: spines. The device contains a heat-exchange device of the type heat pipe coaxially installed in the tank 1 with a collector-condenser 8 located above the intended level of culture liquid and placed in a cooled housing 9. The section of the heat pipe located in the culture fluid 1 is made in the form of two cylindrical shells 10 and 11, placed one into the other with the formation of an annular gap 12 for the refrigerant and plugged at the ends by the annular plates 13 and 14. In the upper plate 13 there are holes 15 for the tubes 16, said heat pipe, located in the culture fluid, with a collector-condenser 8. The device has water pipe 16 for supplying the nutrient medium. The proposed apparatus works as follows. The fluid is sucked in by a rotating turbine wheel 2, and then with great bluntness is ejected into the annular channels 7 of the annular chamber 6 ". Due to the pressure drop in the annular channels 7, air is sucked into the annular chamber 6 and crushing it in the liquid phase to the smallest bubbles: . You move out of chamber 6 a gas-liquid mixture. rises up into the space formed by the tank 1 and the cylindrical shell 11 of the heat pipe; in this case, when overflowing through the upper edge of the heat pipe, the air is partially separated from the liquid phase and exits through the exit hatch, and the liquid goes down along the cylindrical shell Yu and is again taken up by the turbine wheel 2, which allows for the continuous aeration of the medium. In the process of microbiological synthesis, there is also: excess heat ,. as a result, the refrigerant in the annular gap 12 of the heat pipe (in the example, (} reon) boils, and the vapors formed during boiling are discharged through the tubes 16 to the collector-condenser 8 located outside the tank 1, where they condense, and the condensate that forms back to the annular gap under the action of the force of gravity. The implementation of the processes of CyPen - condensation in a closed contour of the heat pipe and the circulation of the culture fluid between its walls increase the thermal stabilization inside the apparatus and accelerate the process. a microorganism extractor containing a tank, an aerator and a heat exchange device of the heat pipe type with a collector-condenser located above the estimated level of the liquid culture group placed in a cooled jacket, which is so as to increase the productivity by accelerating the process teplosema, the section of thermal coarse, located in the culture fluid, is made in the form of two cylindrical shells, placed one in the other with the formation of an annular gap for the refrigerant, n and wherein the upper part communicates with a collector mantle, condenser by pipes.
