Simple, efficient automated all-grain beer brewing system
The present invention provides a method to create and a process for using a compact, automated, all-grain beer brewing appliance. The method may include a microprocessor-based Process Control System, a Heat EXchanger loop, a Fluid Distribution Manifold, a Step Filter Basket, a Hot Fluid Tank, pumps, valves, plumbing and brewing control instruments. The invention may also make use of a Filter-Keg in lieu of a Hot Fluid Tank allowing fermentation, conditioning and dispensing from a single replaceable vessel.
1. A brewing system, comprising:
a. a vessel, constructed to retain water and beer wort;
b. a filter basket designed to drain into said retaining vessel comprising a bottom wall defining a set of apertures permitting fluid flow into said vessel, an exterior wall set, adapted to retain fluid within the filter basket at levels below a top fluid level, and a set of interior walls, configured to define a single largest open compartment, taking up at least one quarter of the area of said filter basket and, and a set of additional open compartments;
c. a tube connected to and in fluid communication to said retaining vessel
d. a fluid distribution manifold connected to said tube and adapted to controllably direct fluid from said tube into a selected open compartment;
e. a heat source positioned to be in thermal communication to fluids in said system;
f. a pump adapted to pump fluid through said tube;
g. a control unit in communication with and controlling said pump, said heater and said fluid distribution manifold; and
h. whereby malted barley can be placed in said single largest open compartment, water placed in said retaining vessel, and hops placed in one of said additional open compartments, said water then pumped through said tube by said pump, heated by said heat source, and directed by said fluid distribution manifold to cause hot water to flow through said malted barley, and into said vessel, and later to flow through said compartment containing said hops and into said vessel, thereby creating hot hops-infused beer wort.
2. The system of claim 1 , wherein said filter basket is a step filter basket, wherein said interior walls permit fluid flow between compartments at fluid levels below said top fluid level.
3. The system of claim 2 , wherein said interior walls permit fluid flow between a subset of adjacent compartments at varying fluid levels, so fluid will flow over different compartment contents at different times during brewing.
4. The system of claim 2 , wherein said fluid distribution manifold is in the form of a moveable fluid outlet responsive to said control unit to move to a commanded position above a selected compartment.
5. The system of claim 3 , wherein said subset of adjacent compartments is arranged to enable a sequence of adjunct additions, with compartments designated for later adjunct additions configured to permit fluid flow into compartments designated for earlier additions.
6. The system of claim 5 wherein said control unit directs fluid flow sequentially to said compartments in predetermined order of adding of adjuncts.
7. The brewing system of claim 1 , wherein said control unit includes a data entry panel whereby a user can input commands.
8. The brewing system of claim 1 , wherein said heat source is a heat exchanger that is, more specifically, in thermal contact with said fluids in said tube.
