SU231508A1 - Apparatus for continuous fermentation of mash on pulp - Google Patents

Description

I Known apparatus for the continuous dumping of wort on the pulp, made in the form of a tank with connections for loading the pulp with the wort and discharging them after fermentation, equipped with a discharge screw and a device for trapping aromatic substances.

The proposed apparatus provides the possibility of a longer contact of the solid particles of the pulp with the wort as a result of repeated circulation of the fermenting wort and irrigation of the pulp with it and to intensify in this way the process of extracting aromatic, dyeing and tanning substances from the pulp.

To do this, in the center of the tank, concentrically installed facing the large base of the V1shz truncated cone for the pulp, forming a chamber for the wort and carbon dioxide gas with the walls of the tank; the lower part of the cone on the side surface has a perforation, and the upper part is connected by means of a transition pipe with a discharge screw; moreover, the tank is equipped with two external circumferential compasses circular tubes with pumps connected to the bubblers, respectively located in the upper part of the cone and at its bottom.

A cylinder connected to the bypass pipe connected to the bubbler is placed at the top of the cone.

The branch pipe for feeding the pulp can be located inside the cone, in its central part.

The drawing shows a schematic of the apparatus.

It consists of a tank 1, equipped with nozzles 2, 3, 4, and 5, respectively, for loading pulp, discharging wine, completely emptying wine, sediment and wash water, and auger 6 for unloading splashed and fermented pulp.

In the center of the tank, a truncated, w-shaped cone 7, designed for pulp (chamber a) and forming an annular chamber with masts for wort and carbon dioxide gas with the walls of the reservoir, is installed casually in a large base facing down. The tank is equipped with two circulating liquid bypass liquid pipes 8 and 9 with pumps 10 and 11, to which bubblers 12 and 13 are located, located at D1shchsha and in the upper part of the cone. Pipe 8 G1) .x; is designed for 1 barrel of fermenting liquid from the top of the tank to the bottom, and pipe 9 to feed the liquid in the opposite direction. There is fuse-1 for the introduction of carbon dioxide into chamber a for the additional fleet of the first pulp.

A thin valve 14 and a three-way valve 15 connected to the gas chamber e and to the bypass pipe 8. The container is equipped with a condenser 16 for trapping alcohol and aromatic substances, and for cooling the fermenting wort heat exchanger 17.

A sprinkler (nozzle) 18 is located above the discharge nose 6 for supplying the wort to the pulp layer, connected to the bubbler 13 via a three-way valve 19 into one common pipe.

Fermentation of the wort on the pulp is as follows.

The container 1 is filled with pulp before the whole part of the cone is immersed in the wort and the yeast is wired.

In the process of filling the apparatus with pulp, the wort is separated and fermented, while its solid particles are entrained upwards by carbon dioxide and form a nipple. New portions of the pulp fed through pipe 2 into the middle part of chamber a are deposited on the bottom and shifted with the partially fermented wort. The incoming pulp displaces the previously formed cap to the screw 6, which feeds it to the pressing.

To cool the fermenting wort, taps 20 and 21 are opened; include the heat exchanger 17, the pump 11 and pump the wort from the bottom of the tank through the bubbler 13 to the top. After the tank is filled and the filler is formed, the cooled wort is fed through the three-way valve 19 simultaneously to the sprinkler 18, which results in a more complete extraction of the pulp before it is unloaded from the apparatus. The level of elevation of the clamp in the chambers of visas is regulated by the change in pressure of carbon dioxide.

Increasing gas pressure causes a decrease in the level of wine in chamber b and an increase in chamber a; accordingly, the folder also rises. The reverse result is achieved by lowering the gas pressure in chamber c. In order to increase the lift, the caps turn on the pump 10 and pump the wine from the top of the tank through the pipe 8 through

bubbler 12 into the middle part of the chamber a. The jet of wine at the same time sucks the excess carbon dioxide released through the safety valve 14 from the chamber. For the trapping of alcohol and aromatic substances that are entrained by the flow of carbon dioxide, a capacitor 16 serves.

Claims (3)
