Lauter tun false bottom
View Patent ↗A system for filtering spent grains from unfermented beer is disclosed. The system has a pot assembly having a stock pot wall, lid, drain tube and outlet valve. A louvered false bottom is positioned in the pot assembly and forms an opening between the false bottom and the stock pot wall. The louvered false bottom has a plurality of raised louvers spaced over the false bottom. Each of the louvers has a top surface, a bottom surface, a leg and a slot. The slot can be made larger or smaller according to the grain crush size.

5. The brewing apparatus having a filtering system therein for filtering a spent grain from an unfermented liquid of claim 1 wherein said stock pot wall has a ledge and said bottom surface of said false bottom and said ledge are in a sealing relationship.
6. The brewing apparatus having a filtering system therein for filtering a spent grain from an unfermented liquid of claim 1 wherein said plurality of raised louvers have a profile and said profile being one of a square, a rectangular, a triangular, a hexagonal and an oblong configuration.
7. The brewing apparatus having a filtering system therein for filtering a spent grain from an unfermented liquid of claim 1 wherein said plurality of raised louvers have a pattern and said pattern being one of a staggered, a random, and a chevron.
8. The brewing apparatus having a filtering system therein for filtering a spent grain from an unfermented liquid of claim 1 wherein said pot assembly has a circular configuration and said outer edge of said false bottom has a circular configuration.
9. The brewing apparatus having a filtering system therein for filtering a spent grain from an unfermented liquid of claim 1 wherein said pot assembly has a rectangular configuration and said outer edge of said false bottom has a rectangular configuration.
10. The brewing apparatus having a filtering system therein for filtering a spent grain from an unfermented liquid of claim 1 wherein said pot assembly has a preestablished configuration and said outer edge of said false bottom has an identical preestablished configuration.
11. A filtering system, said filtering system filtering a spent grain from an unfermented liquid comprising:
a pot assembly having a stock pot wall, a lid being positioned in sealing relationship with said stock pot wall, and a drain tube extending through said stock pot wall;
a false bottom being positioned in said pot assembly, said false bottom having a top surface and a bottom surface being positioned opposite said top surface, an outer edge, and a plurality of raised louvers extending though said false bottom, each of said plurality of raised louvers having a top surface and a bottom surface being positioned opposite said top surface, a leg extending from said top surface of said false bottom to said top surface of said plurality of raised louvers, and a slot being positioned between said top surface of said false bottom and said bottom surface of said plurality of raised louvers;
an opening interposed said bottom surface of said false bottom and said stock pot wall, said opening including a drain tube hole through which is positioned said drain tube, said drain tube exiting said stock pot wall; and
an outlet valve being positioned externally of said pot assembly and being connected with said drain tube.
12. The filtering system of claim 11 wherein said leg has a preestablished height, said preestablished height being determined by a grain crush size of said spent grain.
13. The filtering system of claim 11 wherein said slot having a preestablished open area, said preestablished open area being determined by a grain crush size of said spent grain.
14. The filtering system of claim 11 wherein said outer edge of said false bottom and said stock pot wall are in a sealing relationship.
15. The filtering system of claim 11 wherein said stock pot wall has a ledge and said bottom surface of said false bottom and said ledge are in a sealing relationship.
16. The filtering system of claim 11 wherein said plurality of raised louvers have a profile and said profile being one of a square, a rectangular, a triangular, a hexagonal and an oblong configuration.
17. The filtering system of claim 11 wherein said plurality of raised louvers have a pattern and said pattern being one of a staggered, a random, and a chevron.
18. A method of filtering a spent grain from an unfermented liquid, said method of filtering comprising the steps of:
removing a lid from a pot assembly;
positioning a false bottom within said pot assembly, said false bottom having an outer edge and said pot assembly having a stock pot wall, said outer edge and said stock pot wall being in sealing relationship preventing sidewall shunting of said spent grain;
positioning a plurality of raised louvers in said false bottom, said plurality of raised louvers forming a slot and a leg;
positioning said leg of said plurality of raised louver toward said lid;
forming an opening below said false bottom and a bottom of said pot assembly, said unfermented liquid draining though said slot of said plurality of raised louvers;
