Abstract
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.
Claims19
A brewing apparatus having a filtering system therein for filtering a spent grain from an unfermented liquid, said filtering system comprising:
- one of a lauter tun and a pot and 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.
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.
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;
- maintaining said spent grain above said opening with said leg;
- draining said unfermented liquid from said opening wherein said opening comprising the step of said false bottom including a drain tube hole having a drain tube positioned therein and exiting said stock pot wall of said pot assembly and draining through an outlet valve.
