Description

The invention relates to the wine industry and can be used in the production of white and red canteens and fortified wine materials.

The aim of the invention is to increase productivity and improve the quality of fermented wort.

FIG. 1 shows a plant for fermenting wort on pulp, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a section bb of fig 1; FIG. 4 is a section B-B in FIG. one ,

The wort fermentation unit consists of a vertically mounted cylindrical tank with a cone-shaped bottom 2, a lid 3, a loading nozzle 4 and a discharge hatch 5, which is hinged to the cone-shaped bottom and the hydraulic cylinder 6.

In the lower part of the cylindrical tank 1 parallel to the plane of symmetry of the cone-shaped inclined bottom 2, two axes 7 are mounted with dividers 8, to which the curtains 9–12, made in the form of plates, are suspended.

Two rows of curtains 9–12 divided the cone-shaped bottom 2 into the middle 13 and the two extreme 14 parts.

In the upper part of the vertical cylindrical tank 1, under the cover 3, a level sensor 15 and a perforated partition 16 are mounted, which freely rest on support ribs 17 rigidly mounted on the cylindrical shell of the tank, with the end portion of the rib inclined.

The perforated partition 16 serves as an abutment for the stem 18 interacting with the sensor 19.

A degassing device 20 is fixed on the lid 3, consisting of a body 21, a lid 22, a discharge pipe 23, a perforated dissector 24 and a hydraulic lock 25, which includes the pipes 26 and 27 and the body 28.

The degassing device 20 is connected to a cone-shaped bottom 2 by a circulation loop including a filter 29 installed vertically in the wort extraction zone, a pipe 30, a pump 31, a three-way valve 32, a pipe 33, a pressure pipe 34.

The installation works as follows

The pulp through the loading nozzle 4 is supplied by the mezzanine pump and fills the cone-shaped bottom 2, the cylindrical tank 1 and, filtering through the perforated partition 16, reaches the level sensor 15, which gives a signal to stop the pulp supply.

In the installation, the processes of insisting and fermenting the wort on the pulp are carried out.

During fermentation, a cap of pulp is formed, saturated with fermentation gases. The cap rises in the upper part of the cylindrical tank 1 and moves in the vertical direction the perforated partition 16 and the rod 18 acting on the sensor 19. At the same time, the pump 31 is turned on, which sucks the wort through the filter 29, pipe 3 and feeds it through the pipe 33 34 degassing devices 20. The wort fills the space between the lid 22 and the perforated divider 24, with a pressure passes through the apertures of the perforated dissector and, in the form of a multitude of thin jets, enters the lower part of the housing 21. Dissection of the wort flow into a multitude of thin

jet contributes to the intensive release of fermentation gases in the wort, and their removal into the atmosphere through the exhaust pipes 23. From the lower part of the body 21, the wort under hydrostatic pressure passes through the hydraulic lock 25, is fed to the wort mirror located above the perforated partition 16, mixed with it. This wort mixture passes through the holes of the perforated partition 16 and evenly penetrates the entire thickness of the cap, loosening the cap at the expense of selecting fermentation gases from it and at the same time washing out useful substances from it. This reduces the pressure of the cap on the perforated partition 16 and lowers it all the way onto the ribs 17, the end of which is inclined to prevent the mash from hanging. Together with the perforated bulkhead, the rod 18 is also lowered, giving through the sensor 19 a signal to a time relay (not shown), by which, for technological reasons, the duration of the circulation cycle can be controlled.

The processes of the present and the fermentation in the installation proceed in isolation from the atmosphere due to the fact that the outlet opening of the nozzle 26 is below the outlet openings of the nozzle 27.

When the present and fermentation processes are completed, the three-way valve 32 is switched and the gravity wort is pumped out by the pump 31 through the filter 29 and the branch pipe 30 for further processing, and the yeast sediment and the weighed pulp, cut by the plate-splitters 8 into three parts, fill the entire volume inclined cone-shaped bottom 2.

After the release of the must-freeze, they start unloading the depleted pulp. To do this, use the hydraulic cylinder 6 to open the discharge port 5 and the yeast sediment, and then the depleted pulp is removed from the tank.

In this case, the depleted pulp is removed in layers with self-regulation using curtains 9-12 as follows. First, the layer of the debilitated pulp adjacent to the shutters 11 is removed from the middle part 13, which is next to the discharge opening of the cone-shaped inclined bottom 2, which then under the action of the layer of depleted pulp adjacent to them from the middle part 4, turn and release these layers. In this way, layers of depleted pulp adjacent to the blinds 12,10,9 are removed successively.

Data on the quality of fermented wort are presented in table.

The table shows that the content of suspended matter in the fermented wort obtained at the pilot plant is less than in the lot of wort obtained at the known plant.

The proposed plant allows improving the quality of fermented wort and productivity by increasing the extraction rate and sugar digestion rate by reducing the degree of compaction of the pulp and reducing the pressure of carbon dioxide in the apparatus.
