Abstract

The present invention provides a unique process and system for brewing beverages for retail or commercial use where the key brewing parameters are independently controlled to produce multi-cup batches of brewed beverage of optimum taste. This invention is applicable to both retail and commercial applications and is scalable in quantities ranging from one cup to three gallons or more of brewed beverage. Since the extraction and solid-liquid separation are conducted separately and independently, the present invention decouples these two operations to avoid reduction in taste quality while still being able to provide large multi-cup batches.

Claims

1. A beverage brewing system, comprising:

an extraction vessel having an open top end, an interior chamber and an exit port;

hopper means for directing beverage solids into the extraction vessel;

conduit means for directing water into the extraction vessel;

means for mixing the beverage solids and water into a slurry;

water-soluble material being extractable from the beverage solids;

control means for heating and controlling the temperature of extraction of the water-soluble material from the beverage solids;

at least one filter vessel having an input port and an exit port;

the exit port of the extraction vessel being connected to the input port of the at least one filter vessel;

each of the at least one filter vessels including filter media;

means for routing the slurry from the extraction vessel through the at least one filter vessel and through the filter media;

brewed beverage being provided at the exit port of the at least one filter vessel;

a brewed beverage reservoir having an input port and an exit port;

the input port being connected to the exit port of the at least one filter vessel to received brewed beverage therethrough for delivery to and storage in the brewed beverage reservoir; and

a valve connected to the exit port of the brewed beverage reservoir;

the valve permitting controlled dispensing of the brewed beverage from the brewed beverage reservoir.

2. The beverage brewing system of claim 1, wherein the at least one filter vessel is two or more filter vessels connected in parallel between the exit port of the extraction vessel and the input port of the brewed beverage reservoir.

3. The beverage brewing system of claim 1, wherein the means for routing the slurry is a positive pressure pump connected between the extraction vessel and the at least one filter vessel.

4. The beverage brewing system of claim 1, wherein the means for routing the slurry is a negative pressure vacuum pump connected to the brewed beverage reservoir.

5. The beverage brewing system of claim 1, wherein the means for routing the slurry is a negative pressure vacuum pump connected to the at least one filter vessel.

6. The beverage brewing system of claim 1, wherein the means for routing the slurry is gravity.

7. The beverage system of claim 1, wherein the means for mixing is a mechanical mixer selected from the group consisting of an agitation blade mixer and a magnetic mixer.

8. The beverage system of claim 1, further comprising:

a recycle return conduit having a first end and a second end;

the first end of the recycle return connected to the exit port of the extraction vessel and the second end of the recycle return being in fluid communication with the interior chamber of the extraction chamber;

the slurry being mixed using jet mixing by recycling slurry back into the extraction vessel via the recycle return conduit.

9. The beverage system of claim 1, wherein the slurry is mixed using both mechanical agitation and jet mixing by recycling slurry back into the extraction vessel.

10. The beverage system of claim 1, further comprising:

means for self-cleaning the system.

11. A process for brewing a beverage, comprising the steps of:

providing an extraction vessel having an open top end, an interior chamber and an exit port;

directing beverage solids into the extraction vessel;

directing water into the extraction vessel;

mixing the beverage solids and water into a slurry;

water-soluble material being extractable from the beverage solids;

heating the slurry and controlling the temperature of extraction of the water-soluble material from the beverage solids;

directing the slurry with extracted water-soluble material to at least one filter vessel;

filtering the beverage solids from the slurry leaving brewed beverage;

routing brewed beverage into a brewed beverage reservoir;

dispensing brewed beverage from the brewed beverage reservoir.

12. The process of claim 11, wherein the at least one filter vessel is two or more filter vessels connected in parallel between the exit port of the extraction vessel and the input port of the brewed beverage reservoir.

13. The process of claim 11, wherein the slurry is directed to the at least one filter vessel by a positive pressure pump connected between the extraction vessel and the at least one filter vessel.

14. The process of claim 11, wherein the slurry is directed to the at least one filter vessel by a negative pressure vacuum pump connected to the brewed beverage reservoir.

15. The process of claim 11, wherein the slurry is directed to the at least one filter vessel by a negative pressure vacuum pump connected to the at least one filter vessel.

16. The process of claim 11, wherein the slurry is directed to the at least one filter vessel by gravity.

17. The process of claim 11, wherein the wherein the beverage solids and water are mixed into a slurry by a mechanical mixer selected from the group consisting of an agitation blade mixer and a magnetic mixer.

18. The process of claim 11, further comprising the steps of:

mixing the beverage solids and water into a slurry by jet mixing from recycling slurry from the exit port of the extraction vessel and back into the interior chamber of the extraction vessel.

19. The process of claim 11, wherein the beverage solids and water are mixed into a slurry by mechanical agitation and jet recycle mixing.

20. The process of claim 11, further comprising the step of:

cleaning the extraction vessel and the at least one filter vessel.
