RU75390U1 - DEVICE FOR CULTIVATION OF MICROORGANISMS - Google Patents

Abstract

The utility model relates to the microbiological industry and can be used in the food industry. The apparatus for the cultivation of microorganisms contains a container (1) with a mixing device. Under the lid of the container (1), a two-tier barrier net (8) with sharp spikes (9) and (10) of different heights is installed, and the spikes of the same height are staggered. The technical result of the utility model is to reduce the foam shells, slowing the gas exit rate, reducing the removal of useful substances from the apparatus. 1 ill.

Description

The utility model relates to the microbiological industry and can be used in other industries, in particular, food.

A known apparatus for growing microorganisms, containing a container placed inside it with an agitator, consisting of discs tiered on a shaft and nozzles for supplying nutrients, aeration gas and exhaust gas and finished product (see RU 47888 U1, C12M 1/04, 10.09 .2005).

The disadvantages of this apparatus include increased pricing, leading to the removal along with the foam of beneficial microorganisms.

Closest to the technical nature of the claimed utility model is an apparatus for the cultivation of microorganisms, containing a container, a mixing device located inside it, consisting of three mixers, tier mounted on the shaft and nozzles for introducing a nutrient medium, aeration gas and exhaust gas and finished product ( see RU58534U1.C12M 1/04, 11/27/2006).

The disadvantages of this device include increased pricing, in connection with which there is a removal of beneficial microorganisms from the device, which ultimately reduces the quality of the finished product.

The technical task of the utility model is to improve the quality and yield of the finished product.

The technical result of the utility model is the reduction of foam shells, the slowing down of the gas exit rate, the reduction of the removal of useful substances from the apparatus.

The specified technical result is achieved by the fact that in the apparatus for the cultivation of microorganisms containing a container, a mixing device located inside it, consisting of three rows of mixers, tier mounted on a hollow shaft and pipes for introducing a nutrient medium and aeration gas, exhaust gas and finished product, according to a utility model, under the lid of the tank is fixed a two-tier barrier net with sharp spikes of different heights, and the spikes of the same height are staggered.

Distinctive features of the claimed utility model is the presence of a new structural element, namely, a barrier net with sharp spikes of different heights, and the spikes of the same height are staggered.

Foam gases formed during cultivation rush to the outlet pipe with great speed, encountering obstacles in their way in the form of a barrier net with sharp spikes of different heights, hitting them that burst, lose their speed. Foam gases breaking through the first tier of the grid are broken into sharp spikes of the second tier. Gases freed from foam shells exit the apparatus through openings in the grid, and useful substances are again involved in the technological cycle.

Thus, the identified distinctive features of the utility model contribute to the elimination of foam shells, reduce

the speed of the exhaust gases, the return of useful substances to the apparatus, which ultimately improves the quality and yield of the finished product.

Barrier mesh made of lightweight, stainless materials.

The utility model is illustrated by drawings, where in FIG. its longitudinal section is shown.

The apparatus contains a vertical tank 1, a mixing device located inside it, consisting of three mixers 2, 3, 4, tier mounted on the hollow shaft 5. In the upper part of the tank 1, nozzles 6 and 7 are installed, respectively, for introducing aeration gas and exhaust gas. Under the lid of the tank 1 there is a two-tier guard net 8 with sharp spikes 9 and 10 of different heights, and the spikes of the same height are staggered.

The apparatus is equipped with nozzles 11,12, respectively, for introducing a nutrient medium and the outlet of the finished product.

The device operates as follows.

Through the pipe 11, the container 1 is filled with a nutrient medium and seed, then aeration gas is introduced through the pipe 6. An electric motor is turned on, which drives the hollow shaft 5 with a stirring device. Due to intensive mixing and aeration, a significant amount of foam is released, falling under the blades of the upper mixer 2. Most of the foam breaks up onto the sharp edges of the blades, the rest goes to the barrier net 8 with sharp spikes 9 and 10. Foam shells with gases, meeting with sharp spikes, crash, lose their speed. Foam membranes that are not broken in the first mesh break into sharp spikes during

second barrage grid. Finally freed from the foam shells, the exhaust gases rush into the atmosphere through the pipe 7.

Useful substances are returned back to the tank 1. The finished product is removed through the pipe 12.

Claims (1)

An apparatus for cultivating microorganisms containing a container, a mixing device located inside it, consisting of three mixers tiered on a hollow shaft, nozzles for introducing a nutrient medium and aeration gas, exhaust gas and finished product, characterized in that a two-tier is installed under the lid of the container fence net with sharp spikes of different heights, and the spikes of the same height are staggered.
