Description

This invention relates to the microbiological industry. The known installation is dp of concentration of enzyme solutions, containing a vertical chamber, the inside of which is mounted With the possibility of an oscillatory motion spiral. Also known is the installation of dp konaytrirovaniya enzyme solutions, which is the closest solution to the invention to the technical essence and achievable "y result and contains a vertical re | 3 valve, spray nozzles dp heating, as well as nutrient and discharge nozzles. However, in these plants, the heat exchange surface is not sufficiently developed, the contacting of the evaporated solution with the heat agent is short, and an increase in the evaporation temperature leads to the activation of enzymes, as a result of which the intensity of the process is not very high, and the activity of enzyme preparations, O9, in the cupral liquid, no msvc persist. For the purpose of intensifying the process and preserving the activity of enzyme preparations contained in the culture medium, the described installation for concentrating enzyme solutions is additionally equipped with a reservoir having a vibrator and divided into multi-layered chambers with a corrugated heat exchange surface, communicated between themselves successively large n the smaller base of the micro-, receiving tank mounted on the branch patra & ke and a collection with a vacuum pump,} iodoedane piping system to the main pipe to form a circulation system. FIG. 1 is a schematic representation of the setup dp of concentrating enzymatic pactw thieves, common wit: FIG. 2 shows a section A-A in FIG. on fig.Z - section bb in figure 1. The installation consists of a vertical tank 1 with a tangentially connected supply pipe 2 for introducing an evaporated solution, spray fsuns 3 dp for heating, for example, hot air, a discharge pipe 4, on which the receiving tank of the 5- and vertical container 6 is installed.

The reservoir 6 is divided along the height of the chambers dp entering the heat carrier, embedded in the form of truncated truncated cones 7 with a corrugated heat transfer surface. The chambers are separated one from the other by sealed peregorodok 8 and hydraulic gates 9. In the upper part of each chamber there is a power supply in the form of a system of branch pipes Y. against the paraplepno-conical shell.

Nozzles 1O have nozzles (not shown in the drawing), mounted so as to ensure the tangential direction of the evaporated liquid relative to the heating surface. Each chamber is equipped with nozzles 11 dp for heating agent input, nozzles 12 dp for introducing a cup of liquid, and nozzles 13 dp for condensate drain. The lower chamber of the tank 6 is equipped with a vibrator 14, the chambers are connected to each other by alternately large and smaller bases 15, "16 cones.

The plant is equipped with a collector 17 with a vacuum pump 18 and a circulating pump 19 with the formation of a circadian system, the upper chamber of the tank 6 communicating with the receiving tank 5 with pipeline 2O, to which the bypass pipeline 21 is connected to the supply pipe chamber of tank 6 through circulation pump 19, collector 17 and distribution pipe 22.

The installation works as follows.

The liquid to be evaporated is tangentially injected through the pipe 2 into the upper part of the tank 1.

The created vortex flow of liquid falls, and hot air is fed in through the spray nozzles 3.

The partly evaporated Gypkosg is discharged through pipe 4 | B i inlet-tank 5 and then through pipeline 2Q into the upper chamber of the tank 6 and successively flows inside the chambers 7. A vacuum pump 18 is created in each chamber corresponding to an evaporation temperature increases sequentially from top to bottom.

The inside of each chamber 7 is introduced tangentially through the nozzles 12 into the cupral liquid, and through the nozzles 11 into the body - heatgen in the form of steam or water.

The vibrator 14 informs the tank 6 to vibrate. Condensate is discharged from each chamber through a nozzle 13.

In the process of evaporation, the liquid is circulated through the container 5 through the pipeline 2O into the upper chamber of the tank 6, flows successively through the chambers 7, from the lower chamber through the pipeline 22 into the collector 17, then the circulation pump 19 to the distribution pipeline 21 as streams to the upper zone of tank 1 or b (depending on the degree of evaporation).

Then the circulation continues until the solution is completely evaporated at the required concentration.

The described installation allows, in comparison with the known process, to intensify the process, to ensure the preservation of the activity of enzyme preparations at a relatively low temperature (30-40 ° C) of the process.
