Abstract

Use: to obtain products from materials of plant origin in the form of biologically active drugs that increase the resistance of plants to adverse conditions of the external environment. The essence of the invention: the reactor contains a cylindrical tank mounted on a horizontal shaft. The container has two walls with the formation of an annular cavity for the supply of gas. This cavity communicates with the nozzles placed on the inner wall of the vessel. Each nozzle is equipped with a pneumatic valve for the periodic supply of gas into the container. 1 hp ff, 2 ill.

Description

The invention relates to biotechnology, in particular, to devices for the aerobic microbiological decomposition of biological substrates, and can be used to obtain seedlings, products that increase the resistance of biological organisms to adverse environmental conditions, from materials of plant origin.

- A bioreactor for the processing of plant materials is known, containing a cylindrical horizontal container with a loading hatch mounted on a horizontal shaft rotatably and driven, and blades located in the container, reinforced evenly around the circumference on the inside wall for sewing medium and air dispenser.

The disadvantage of this bioreactor design is a non-rotating end.

an air duct located in the body of the bioreactor that does not allow to create a uniform aeration of the medium consisting of materials sticking and winding around the air duct during operation of the bioreactor and inhibiting the movement of the body of the bioreactor.

Closest to the present invention is a bioreactor for the cultivation of microorganisms, consisting of a rotating drum with a mesh cavity in the inner part of the bioreactor tank with air supply in the section for distribution to the processed feedstock.

However, this bioreactor has insufficient performance due to incomplete saturation of the medium with a pelvis and low reactor fill factor.

The purpose of the invention is to increase the saturation of the culture medium with gas, increase the filling ratio of the reactor and increase productivity.

The goal is achieved using a bioreactor for microbiological decomposition of vegetable-raw material containing a horizontal cylindrical tank with process nozzles mounted on a horizontal shaft rotatably, having two walls to form an annular cavity between them for supplying gas and an environment aerator placed in the tank moreover, this device contains evenly placed around the circumference on the inner wall of the tank nozzles for introducing gas into the medium, communicated with the stake tsevoy cavity wherein each nozzle is provided inside pneumatic valve for periodically supplying a gas into the container and within the container freely housed in separate filler particles to clean the inner surface of the container and an additional loosening feedstock.

FIG. 1 shows schematically a biorector for the microbiological decomposition of plant materials; in fig. 2 shows section A-A in FIG. one.

The bioreactor is a horizontal cylindrical tank 1 with process nozzles 2, mounted on a horizontal shaft 3 rotatably, having two walls 4 and 5 to form an annular cavity 6 between them for supplying gas and contains nozzles 2 evenly spaced around the inner wall of the tank. for introducing gas into the medium in communication with the annular cavity, with each nozzle 2 being provided inside with a pneumatic valve 7 for periodically supplying gas to the tank 1 and inside this tank I freely The filler 8 is placed in the form of individual particles for cleaning the inner surface of the container and further loosening the raw material.

The bioreactor works as follows. .

Raw materials in the form of crushed biological material (straw, leaves, grain, starch, etc.) are placed through the loading port 9 into the horizontal cylindrical container 1, where the loosely placed filler 8 is also loaded from mechanically strong, inert, wear-resistant material in the form of individual particles, then

it is filled with culture fluid 10. Air flow is switched on, which, passage through shaft 3 and annular cavity b, goes to nozzles 2 with valves 7 and

out of the bioreactor through the other end of the shaft 11.

Then the motor 12 is turned on and, through the reducer 13, the cylindrical horizontal capacity of the bioreactor begins to rotate and

due to this, the entire mass of plant material is periodically moistened with culture liquid 10. through which air (or gas) flows continuously from valve 2 through valve 7, and those pipes that are in the culture liquid pass through gas, and in the volume not filled with the culture fluid, they are closed with a valve 7.

Thus, the proposed design of a bioreactor for the microbiological decomposition of plant materials allows an increase in the productivity of the reactor due to a more complete saturation of the culture medium with gas and an increase in the filling ratio of the reactor with raw materials.
