Description

one

FIELD OF THE INVENTION The invention relates to the microbiological and tonic industry, namely to apparatus for growing microorganisms.

A known apparatus for the cultivation of microorganisms, including a vertical tank, divided in height into sections by re-snapping holes of the liquid flow to the downstream section and reinforced in partitions, cylindrical tubes, the walls of which above the partitions have openings for supplying glasses of culture liquid | l.

This device is closest to the invention in its technical essence and the achieved result.

However, the incomplete use of the working volume of each individual section and of the whole apparatus reduces its productivity.

The aim of the invention is to increase the productivity of the apparatus by increasing the working volume and intensifying the process of mass exchange between air and the culture fluid.

To do this, with each glass, a baffle cap is attached to form a gap in the hole of the upstream partition, while the lower sections of cylindrical cups pa are placed under the slinging and tangential cuts are made in them to curl the flow of the injected gas. Cylindrical glasses are equipped with curved tubes for the supply of culture fluid, located at the level of its upper layer.

FIG. 1; apparatus is shown for; microbial growth, longitudinal section; On FKG, 2 - node I in FIG. Ij in FIG. 3 is a section A-A in FIG. 1,

Claims (2)

The apparatus contains a vertical container 1, divided into sections by partitions 2, which are two parallel disks 3 and 4, between which heat exchange chambers are formed. 7, in the partitions 2, holes 5 are formed, having the shape of a truncated cone, directed by a smaller base downwards. Cylindrical cups 6 are strengthened in peregorotsk 2. In the bottom of each cup 6, located under perox 2, HNferoxcH tangential cuts 7 pl twist the included Boepukh. Directly above the partition 2 b in the walls of each glass 6, holes 8 are made for the entry of the culture fluid. At the level of the upper layer of the culture liquid, which is located on the partition, into glasses. The curved tubes reaching the center 9. A bogus cap 10 is fixed above each cup 6. The upper parts of the cups 6, together with the baffle caps 10, are positioned to form gaps in the conical holes 5 of the overlying partitions 2. The apparatus contains fittings 11-14 for feeding environment and air and exhaust the finished product and exhaust air. The device works as follows. The nutrient medium is fed through the fitting 11 in the upper section. From the bottom through 1 fitting 12: aeration air flows in. When 7 glasses 6 are passing through the tangential slots, the air is curled. Through the holes 8.n glasses 6 enters from the partitions 2 the culture liquid. To improve the mixing, the culture fluid in each section of the upper layer is fed through the bent tube 9 into the cup 6. The flow of the culture fluid is carried out by the dilution created in the center of the cups 6. The air captures the incoming fluid and mixes it upwards in the form of a turbulized film and drops. Such air contact with the culture fluid in the swirling upward flow contributes to a significant intensification of the mass transfer process between them. At the exit of the cup 6, the air-liquid mixture strikes against the fender caps 10 and changes the direction of movement. The liquid flows down and collects over the partitions 2, and the air enters the tangential slots of 7 glasses 6, fixed in the upstream partitions 2; The culture liquid flows from the upstream septum to the lower one located through the koles between the conical holes 5 and the fender caps 10. The flowing culture fluid additionally contacts the air exiting from under the cap 10. Intensive circulation of the culture fluid through cylindrical glasses 6 promotes its good mixing on partitions 2. The constant temperature during the No. 1 growth of microorganisms is supported by. It lives by supplying the coolant to the heat exchange chambers of each partition 2. Placing the upper part of the cylindrical glasses b and the baffle caps 10 directly in the overlying partitions leads to a decrease in the overall height of the apparatus, and consequently, to an increase in its working volume. The air contact with the culture fluid in the swirling flow contributes to the intensification of mass transfer. This increases the productivity of the device. The invention The apparatus for growing microorganisms, comprising a vertical capacity divided in height into sections by partitions with openings for the flow of fluid to the lower section and reinforced in partitions by cylindrical glasses, the walls of which above the partitions have openings for supplying the culture liquid to the glasses, in order to increase the productivity of the apparatus by increasing its working volume and intensifying the process of mass exchange between the air and the culture fluid Strongly over each glass reinforced pneumatic cap positioned to form a gap in the bore upstream baffle, the lower portions of the cylindrical cup disposed below the partition and they are made for the tangential slots; spinning the feed gas stream. 2. The apparatus according to claim 1, of which is that the cylindrical glasses are equipped with curved tubes of the culture fluid supply, located at the level of its upper layer.
