Lautering is the process by which the sweet liquid wort is separated from the solid spent grain. To extract the right amount of protein, sparging water is added at 76 C. This process is known as sparging. Then the separation of solid and liquid is ushered by the Raking Arms present inside the Lauter Tun while the false bottom enables clear filtration of the wort from spent grain.
Later, to optimally utilize all the raw materials we have, the spent grain that is not filtered through the lauter tun’s false bottom is transferred to the spent grain silo and is used as a favorable feed for the animals.
