Abstract: This liquid distributor functions to uniformly distribute a descending liquid stream across the tray for interaction with an ascending vapor stream. It has a feed pipe (6) which delivers the liquid stream to an underlying elongated trough (4). Liquid discharge holes (18) are positioned in the floor (12) of the trough (4). A perforated v-plate (20) positioned within the trough (4) so that liquid from the feed pipe (6) passes through the perforated v-plate (20) before encountering the floor (12) of the trough (4). When liquid passes through the perforated v-plate (20), the stream is divided into smaller streams of lower velocity, providing a more uniform overall flow rate of liquid passing through the trough (4). Liquid is then delivered from the discharge outlets (18) of the trough onto the upper surface of the tray (35) with a substantially uniform flow rate across the trough (4).

Abstract: The invention relates to a combined brewing system for home or small scale brewing of fermented alcoholic beverages, particularly beer, and to a method of making fermented alcoholic beverages. The brewing system comprises a single pressurizable vessel having means for naturally carbonating the beer to the desired level during fermentation, for collecting and substantially separating any sediment from within the vessel and removing it from the vessel while the vessel is under pressure, means for receiving compressed gas for dispense purposes and for maintaining natural carbonation levels, and a draft dispense draw off mechanism for drawing off the contents of the vessel at a desired pressure. The vessel has or is adapted to be coupled with a temperature control system to selectively control the temperature of the contents of the vessel during all stages of processing. Accordingly the vessel or system is capable of accommodating at least the brewing steps of fermentation, natural carbonation, maturation, and draw off so that, in use, the processing is less time consuming and labour intensive compared to other small and large scale brewing processes and the risk of contamination of the contents of the vessel by air and/or undesirable micro-organisms during the brewing process is minimized thereby producing an improved quality beverage.
