During the release process, we need to transfer the wort from the release tank to the jug tank. It can be done by gravity or by pump. Of course, gravity filtration is the best and safest way to protect the false bottom. For professional brewers, it is also possible to transfer the wort by pump, which helps to save time in the juice release. Since the pump is faster than the filtration speed, it may compact the spent grain and cause the pump to dry out, thus destroying the pump. Therefore, there are still some brewers considering some improvements to the brewhouse to better protect the false bottom.
1) Wort grant: It is a simple small tank that is in direct contact with the Lauter tank and the pump is in direct contact with the wort grant rather than the Lauter tank. Therefore, the wort can be filtered into the wort allowance first and then the wort will be pumped into the kettle tank. It prevents the vacuum of the pump and thus protects the false bottom and also the kettle.
2) U-connection: There are two sight glasses. One is installed above the false bottom and the other is installed below the false bottom, which ensures the same pressure above and below the false bottom.
