Abstract

The invention relates to the food industry, in particular, to its wine industry, in particular to installations for the continuous fermentation of wort on pulp. The purpose of the invention is to reduce the loss of wine materials and increase their quality. The plant consists of an installed vertical head fermentation tank and an additional tank. In the head tank there are wort collectors, fixed on the inner surface of the walls of the tank in two Russ. Above the wort collectors of the Upper Rus there is mounted a distributor of foam and fermentation gases, made of mutually intersecting radial and annular grooves located upside down and forming a common chamber with the wort collectors. The additional fermentation tank is connected by pipelines to the upper russ wort collectors, and the upper part of this tank is connected to the distributor of foam and fermentation gases. The fermenting gravity wort from the wort collectors of the upper rus of the head fermentation tank enters an additional fermentation tank. From the latter, foam with suspensions and yeast cells under the pressure of fermentation gases flows through a distributor into the formed "cap" of the pulp. Fermentation gases carry out effective mixing of the "cap" of the pulp, intensifying the process of extraction of phenolic substances. 4 ill., 1 tab.

Description

The invention relates to the food industry, to its wine industry, in particular to installations for the continuous fermentation of wort on the mash.

The purpose of the invention is to reduce the loss of wine materials and increase their quality by intensifying the extraction process.

Fig. 1 schematically shows an installation for the continuous fermentation of the mash on the mash; Fig. 2 shows the assembly of the wort collectors with the distributor of foam and fermentation gases; on fig.Z - section aa in figure 2; figure 4 - section bb in figa

The installation includes a head fermentation tank 1 installed

upright, and additional brood tank 2,

In the head tank there are mixing and unloading devices 3 and 4 on the same shaft, as well as a discharge screw 5 and a pipe 6 for unloading the head of the mash and pressing are mounted. There is a pipe 7 at the bottom of the tank that serves to fill the tank with the mash Wort 8 is intended for sampling wort drift for further processing.

Inside the head tank 1 there are mounted collectors fixed on the inner surface of the walls of the tank 8 made of mutually intersecting radial chambers 9 and an annular chamber 100 Chambers 9 and 10 have perforated walls, the upper shaft of the sjelosbornichev is located under the upper conical-truncated part of the tank 1, and the lower one over the lower truncated-conical part of the reservoir. The annular chambers 9, which form the collectors, are located at a distance from the reservoir axis equal to 0.5-0s7 of its radius. The bottom of the wort collectors have a slope of 10-15e the walls of the tank 1 "

On the upper floor of the wort collectors, there is a coaxially mounted foam and fermentation dispenser, made of mutually intersecting, but not perforated, radial and annular grooves 11 and 129 mounted upside down and forming a common chamber with wort collectors.

The additional fermentation tank 2 has a pipe 13 for draining the fermented wort and a pipe 14 for collecting excess wort flow from the head tank 1.

Additional tank 2 is installed so that its upper edge is lower than the upper russa of the wort collectors of the head tank 1, and connected to wort collectors of the upper rus by pipelines 15 with cranes 160 The upper part of the additional reservoir 2 is connected to the chutes 11 and 12 forming the foam distributor and fermentation gases, pipeline 17 with a tap 180

The operation of the installation is carried out as follows.

The head fermentation tank 1 - to the middle of the upper rune of the collector wort is filled through the nozzle 7 with freshly crushed mash and yeast dispensing. As the sugars are fermented, the evolved fermentation gases begin to form a cap of the pulp. From the moment the required wine materials are attained, the installation is switched to the continuous operation mode. Fresh portions of the pulp are introduced, mixing and unloading devices are put into operation, valve 16 is installed on the flow of the wort from the top of the wort of the collectors to the additional fermentation tank 2, and valve 18 is supplied to the supply of foam with fermentation gases from the additional tank to the distributor formed gutters 11 and 120

The fermenting gravity drift from the wort collectors of the upper russa of the head tank 1 begins to flow into the additional 5 fermentation tank 2, which can be pre-filled with cassy0 Foam with yeast cells formed under pressure during fermentation of the wort

The Q of the fermentation gases begins to flow through the pipeline 17 to the distributor. The cap of the pulp is irrigated from the inside by horizontal streams of foam. Suspension and yeast cells are deposited on

 solid particles of crushed grapes from fermentation Gases, passage through the cap, carry out its effective mixing, which intensifies the extraction of phenolic substances,

Q and are released into the atmosphere. The mez-cap as the head fermentation tank 1 goes to the throat by means of the unloading device 4 through the nozzle 6 is discharged from the reservoir of the voyage and sent to pressing. The wort is fed for further processing.

At the end of the fermentation process, when the wort reaches a certain level, the feed to the head tank of fresh portions of the pulp stops. The wort from the wort collectors 9 and 10 of the upper and lower rus, from the additional fermentation tank 2, and also the wort pressed out of the mash of the collapsed and unloaded by the screw 5, is sent for further processing.

Claims (1)

Claim Installation for continuous fermentation of wort on the pulp, containing a vertically mounted head fermentation tank with mixing and unloading devices and a system of pipelines and pipes for supplying and discharging pulp and must, wort collectors located in the head fermentation tank in two tiers and formed by radial and annular chambers with perforated walls, and an additional fermentation tank, connected by a pipeline with wort collectors of the upper tier of the main fermentation tank, The reason is that, in order to reduce the loss of wine materials and improve their quality by intensifying the extraction process in a main fermentation tank, a foam and fermentation gas distributor is placed on the upper tier of wort collectors, made of mutually intersecting radial and annular grooves mounted upside down and forming with wort collectors a common chamber, while the upper part of the additional fermentation tank is connected by a pipeline with a foam distributor and 25 fermentation gases, and an additional fermentation tank The tank is installed so that its upper edge is below the upper tier of the wort collectors of the head fermentation tank ^ FIG. 1 ^{3 10} FIG. 2
