Title: Rotating supply system for sparging water in brewing beer - has water nozzles attached to knife support arms, reducing contact of water spray with surrounding air
Inventor: LENZ BERNHARD
IPC: C12C7/16
Filed: 1989-12-23
Abstract: The lauter tun contains a rotating knife device for removing the spent grain on completion of the filtration operation, and the supply system for the sparging water is connected to this device and rotates with it. Water is supplied to the sparging system, which consists of a series of downward facing nozzles mounted on the knife support arms, by a central coupling connected to a flexible supply pipe. In the case where the knife support arms are made of a tubular material, this may be used to convey the sparging water to the nozzles. The tun pref. contains the mash and a system of knives attached to rotating support arms. The sparging water nozzles are attached to the arms and are supplied with water by a flexible pipe by way of a central coupling. USE/ADVANTAGE - This invention is used in the brewing of beer. Part of the brewing process consists of passing water through the grains in a lauter tun, which normally contains a rotating knife system which can be raised nad lowered, and a fixed sparging water inlet system which is necessarily located near the roof of the tun. This invention proposes that the water nozzles be attached to the knife support arms, thus reducing the contact of the sparging water spray with the surrounding air and the undesirable increase in its oxygen content. The risk of creating a vacuum in the tun by inadvertently adding cold water to a hot mash is also greatly reduced.
