Description

Devices are known for continuous fermentation during the overflow of a beer wort in an atmosphere of carbon dioxide, made in the form of a closed tank, provided with partitions inside.

The proposed device in comparison with the known ones allows to intensify the process of fermentation and carbonation of beer. For these purposes, the partition walls of the reservoir are installed horizontally, and the ДУ по alternatively do not reach the opposite side of the reservoir, thus forming a zigzag path for the flow of sus. The partitions in the places where the wort flow is turning can be outward. They are knocked out with the edges knocked down to form peaks, which provides for obtaining a gas cushion over the stream of wort and mixing it with carbon dioxide. In the bottom of the tank, conical yeast collectors can be installed. For cooling beer, a rectangular jacketed vessel can be attached to the tank, connected to the tank on the principle of communicating vessels.

The drawing schematically shows a device for continuously.

The vertical reservoir 1 of rectangular shape inside is divided by horizontal ribs 2 arranged one above the other. The partitions 2 are attached to the side walls of the tank, which alternately do not reach the opposite walls, respectively, and have downwardly bent edges at the free ends, forming peaks 5 at the turning points of the stream of wort, the movement path of which is indicated in the drawing by arrows. The tank 1 in the upper part is supplied with an inlet 4 for wort and yeast, a dosing device 5 for yeast, a dosing device 6 for wort, an exhaust valve 7 with a pressure gauge 8 n with a control thermometer 9. At the bottom of the tank there are conical collectors 10 and // for yeast, Equipped with Hbie fixtures 12 for the removal of nx. Above the conical collection. /

L 142610-2,

located visor 13 :. At the end of the tank / there is a rectangular flat vessel 14 with a jacket 15 for cooling, connected; Filling in the lower part with tank 1 according to the principle of communicating vessels; the supply of the hindering agent is made through the pipe 16, and the outlet thereof. - Through pipe 17. Pipe 18 serves to drain the finished beer. :

Pre-hopped sterile And cooled to a temperature of 22-10 ° beer wort continuously enters the tank 1, which simultaneously serves the yeast.

The first portion of the wort, mixed with yeast, gradually flows down the upper horizontal partition to the lower position, etc., the passage to the lower part of the tank / zigzag flow. After filling the tank / to a certain level, the wort access is stopped and the process begins. The resulting carbon dioxide is collected above the stream of wort, under horizontal partitions in the form of a gas cushion, displaces liquid from under it, and after the gas pressure reaches the required value, and the liquid level under the partition decreases below the canopy 3, the gas is pulled out - under the septum, mixes the liquid and falls under the dislocated partition, etc., thus creating continuous mixing of the liquid in the direction opposite to the flow of the liquid. After the first beers reach readiness, a continuous removal of the cornfield through the nozzle 18 and the supply of the wort in the appropriate quantity starts from the tank. In the future, the process is carried out continuously.

According to the conclusion of the All-Union Scientific Research Institute of the Brewing Industry and the Moscow Institute of Technological Industry, the design of the proposed apparatus allows for an intensive mixing of the cornfield and yeast, and a quicker increase in temperature. A multi-cascade setup to produce cornfields in a continuous stream allows for the production of good quality beer and shortening the fermentation time compared to the natural method.
