Abstract
The present invention is directed to a filter arrangement with a false bottom for a beer-brewing system, with the false bottom being movable for extracting wort from grain by gently squeezing a grain bed in a generally widely distributed application of the squeezing force to mitigate a likelihood of overly compressing grains in the grain bed.
Claims14
A filter arrangement for use with a brewing kettle of a beer-brewing system, the filter arrangement comprising:
- a filter body having a lower end and an upper end and configured to be placed in a brewing kettle during a mash cycle, the filter body having perforated outer walls defining a filter cavity configured to hold grains defining a grain bed during the mash cycle;
- a cover configured to removably connect to the filter body to overlie the upper end of the filter body;
- a false bottom movably held in the filter cavity, the false bottom configured to move from a mashing position toward the lower end of the filter body during the mash cycle to a squeezing position toward the upper end of the filter body after completion of the mash cycle;
- wherein the false bottom in the squeezing position squeezes the grain between the false bottom and the cover to extract wort from the grain and release the extracted wort through the filter body into the brewing kettle, and
- a lift element extending from the false bottom through the cover for moving the false bottom from the mashing position to the squeezing position, wherein the lift element is defined by an infusion tube arranged generally vertically within the filter cavity and configured to deliver water or wort through the filter body during the mash cycle.

A filter arrangement for use with a brewing kettle of a beer-brewing system, the filter arrangement comprising:
- a filter body having a lower end and an upper end and configured to be placed in a brewing kettle during a mash cycle, the filter body having perforated outer walls defining a filter cavity configured to hold grains defining a grain bed during the mash cycle;
- a cover configured to removably connect to the filter body to overlie the upper end of the filter body;
- and
- a false bottom movably held in the filter cavity, the false bottom configured to move from a mashing position toward the lower end of the filter body during the mash cycle to a squeezing position toward the upper end of the filter body after completion of the mash cycle, wherein the false bottom in the squeezing position squeezes the grain between the false bottom and the cover to extract wort from the grain and release the extracted wort through the filter body into the brewing kettle;
- wherein the false bottom is defined by a mash plate assembly that is configured to support the grain bed from below and direct flow of the water or wort through the grain bed.

A beer-brewing system, comprising:
- a brewing kettle;
- a heating system for heating the brewing kettle;
- a recirculation system for moving liquid contents through the brewing kettle;
- and
- a filter arrangement for delivering water or wort within the brewing kettle, the filter arrangement including:
- a filter body configured to be placed in the brewing kettle during a mash cycle and having lower and upper ends and a filter cavity configured to hold grains defining a grain bed in the filter cavity during the mash cycle;
- and
- a false bottom arranged in the filter cavity and configured to move between:
- a mashing position at which the false bottom is positioned relatively further from the upper end of the filter body for loosely supporting the grain bed to facilitate the agitation of the grains in the grain bed by a flow of the liquid contents through the brewing kettle;
- and
- a squeezing position at which the false bottom is positioned relatively closer to the upper end of the filter body to squeeze the grain in the upper end of the filter body and release the extracted wort through the filter body into the brewing kettle.
