Verfahren zur Gewinnung eines Aromakonzentrats aus einem aromahaltigen Saft, dadurch gekennzeichnet, daß der aromahaltige Saft einem Eindampfteil (8) eines ersten Verdampfers (2) zugeführt und dort teilweise eingedampft wird, daß in dem Eindampfteil (8) dieses ersten Verdampfers (2) entstehender Brüden als Heizmittel einem Heizteil (16) eines zweiten Verdampfers (4) zugeführt wird und daß der als Heizmittel dem Heizteil (16) des zweiten Verdampfers (4) zugeführte, nach Beheizung dieses Heizteils nicht kondensierte Brüden abgeführt (36) und zur Gewinnung von Aromakonzentrat kondensiert wird.

Vorrichtung zur Verteilung einer aus einem Ende eines Zuführungsrohrs in einen Verteilerraum eintretenden Flüssigkeit auf einen den Verteilerraum unten begrenzenden, mit Durchbrechungen versehenen Boden, insbesondere Rohrboden oder Schlitzboden, gekennzeichnet durch wenigstens eine in dem Verteilerraum in Abstand von dem Ende des Zuführungsrohrs angeordnete Prallplate, die auf sie treffende Flüsigkeit zu an ihrem unteren Rand befindlichen, abwechselnd nach beiden Seiten gekrümmten Schränklappen umlenkt.
摘要:
The invention relates to a plant for de-alcoholizing a product containing ethanol, for example beer or wine, which plant comprises a preheating stage (5) for heating up the product and an evaporator arrangement (1) drawing product vapours from the product heated up in the preheating stage (5) and discharging the de-alcoholized product. A mechanical vapour compressor (33) compresses the product vapours from the evaporator arrangement (1) and supplies the compressed product vapours to the evaporator arrangement (1) for the heating thereof. In order to heat the preheating stage (5), product vapours from the evaporator arrangement (1) are supplied to the preheating stage (5) through a bypass route (37, 39) to the mechanical vapour compressor (33), at least a part of the product vapours being condensed by means of the preheating stage (5). The bypass route preferably includes a thermal vapour compressor (39).

The invention relates to an installation for the distillation of drinking alcohol, especially whiskey, comprising a distillation column (5) stripping the crude alcohol vapors from the fermented mash and a rectification column (17) increasing the alcohol content of the crude alcohol. At least a part of the crude alcohol vapors of the first distillation column (5) is condensed in an evaporator, especially a falling film evaporator (39), thereby producing low pressure water vapor from preheated fresh water or the distiller's wash or expansion vapors from the distiller's wash, the pressure and/or temperature thereof being increased in a mechanical condenser (49) and being fed to the distillation column (5) or another distillation column stripping the alcohol vapors from the fermented mash, to heat the same. The energy requirement of the distillation installation can therefore be reduced. Since the mechanical condenser does not condense alcoholic vapors but water vapor, the condenser (49) does not require an explosion-protected design.

The aim of the invention is to produce alcohol from plant-based raw materials while reducing energy consumption. Said aim is achieved by separating the husk portion of cereals during grinding and feed said husk portion to a dryer (21) which dries distiller's wash as a carrier medium for distiller's wash. The lost heat of said dryer (21) is supplied to the distillation station (15) as process heat. The lost heat of a molecular sieve (45) that drains the raw alcohol is also redirected to the distillation station (15) as process heat.
