Method and device for treating flowers

As is known, the quality of the wine to be obtained can be improved and the treatment time of the grapes can be reduced by heating the grapes during the first treatment stage, i.e. immediately after the grapes have been harvested and before they are fermented. ₍ Han has found that this warming of the mash accelerates the coloration of the wine, with the result that the contact time between the fruit juice and the pulp can be reduced «

For this reason, with today's devices, the picked grapes are brought to an appropriate temperature heated, subjected to a pass-down reduction, the 20 minutes, and then to separate as much of the juice as possible, which goes straight into the FermentfcLon troughs is conducted, a draining process is carried out, while the clad pomace is fed to a press.

The drip troughs have very large dimensions and are therefore very space-consuming. It is required several to arrange such troughs one behind the other and to achieve sufficient juice separation and to achieve that the juice content of the marc remains below 10%. Finally, it is necessary to use presses with very high pressure, in order to be able to separate a substantial part of the remaining juice from the pomace.

According to the invention, significantly better results are achieved in that the drip troughs are omitted and replaced by a centrifugal separator. The dimensions of a centrifugal separator are much smaller with the same output, it delivers a very finely chopped pomace with a juice content of less than 10% _; and it creates the possibility to squeeze out this marc with much lower pressures than that through

a series of draining troughs has emerged. y

The drawing shows an embodiment of the invention "for example, and that is the only! figure the device in a schematic representation.

The grapes are input to a receiving vessel 1, from which the slurry is fed by a pump 2 into a heat exchanger 3 in which it is brought to the desired temperature, by hot water _heating: ser, which ggeLiefert of a boiler 3a and by a pump 3 ″ b is set in circulation. The mash heated in this way is then placed in crushing containers 4 and 5 connected in parallel, from where the pump 6 conveys the mash into a centrifugal separator 7. At the periphery of the same, the feed pump is drawn off and through the Line 8 passed into trough 9, while the pomace remaining in the axial area of the separator falls into press 10, from the bottom of which the press must obtained is drawn off by pump 11 and also conveyed into trough 9, "while the pressed pomace is ejected at 12 will. While the residues settling on the bathing of the trough 9 and the filter 1 # are collected at 15 and 16, the pre-clarified must at the outlet of the trough 9 is conveyed by a pump 13 into a rotary filter 14 and further fed into a first cooling stage 17 , whereupon the must is introduced into fermentation vessel 19. Delivered by the pump 20

Detergent cold water feeds the first cooling stage 17 and one second cooling stage 21, through which the pump 22 passes a portion of the clear juice accumulating in the lower part of the fermentation troughs 19 and, after cooling, into a higher area of the fermentation troughs.

Of course, the invention is not limited to the illustrated embodiment.

Claims (2)

PATENT CLAIMS fty device for treating grapes by heating them, characterized by a centrifugal separator, into which the heated mash supplied by crushing troughs is introduced and there is divided into first must and finely crushed pomace with a juice content of less than 10%, by a continuous press,
in which the marc is introduced, whereby the in the
Press the resulting press must is mixed with the gate must for the further clarification treatment, and through a device for further compression of the press leaving,
essentially juice-free pomace. " 2. Apparatus according to claim 1, characterized in that the applied for the same output of treated grapes Pressure is lower than that of conventional treatment devices. 3 · Method of.heating grapes the same, characterized in that the heated one of the comminution streams delivered mash into a centrifugal - 6,309 8 28/0 367 Separator introduced and there in Vorlaufmoat and fine crushed pomace with a liquid content of less than 10%, the pomace in a through-feed press introduced and there resulting press must mixed with the flow must for further clarification, and Finally, the essentially juice-free pomace leaving the press is otherwise compacted. 309828/0367
