System for brewing and serving a hot beverage
First Claim
1. A hot beverage brewing and serving system, comprising:
- a brewing vessel for brewing separate batches of hot beverages at a temperature in a brewing temperature range;
an insulated storage tank for storing a batch of a beverage brewed in the brewing vessel at a temperature in a storage temperature range so that the beverage from the same brewing vessel may be simultaneously brewed and served, the storage temperature range being lower than the brewing temperature range;
a serving tap remote from the brewing vessel and storage tank;
a first feed line for carrying the beverage from the brewing vessel to the storage tank;
a second feed line for carrying the beverage from the storage tank to the serving tap for dispensing the hot beverage; and
means for maintaining the beverage in the second feed line at a serving temperature so that when the serving tap is operated after a period of inoperation, it serves the beverage at the serving temperature, the serving temperature being lower than the storage temperature range.

Abstract
A method and system for brewing one or more hot beverages, such as gourmet coffees. The gourmet coffee is brewed, at a brewing temperature, in the liners of a brewing urn. After brewing, the coffee can be transferred to any one of three storage tanks by means of manual or solenoid valves, and, if desired, a gravity-assist pump. The shelf-life of the brewed coffee is increased substantially when stored at a serving temperature which is lower than the brewing temperature. Coffee contained in feed lines leading from each of the storage tanks passes through a pressurizing line to a tap tower located to provide efficient service to the coffee-purchasing customers. Hot water from the water jacket of the brewing urn is circulated in hot water lines retained in close proximity to the feed lines between storage tanks and the tap tower, thereby keeping the coffee in the feed lines at a desirable serving temperature. A control panel connected to level sensors in each of the storage tanks provides visible and audible indications to the operator that the supply of coffee in a particular storage tank is running out, so that the operator can brew a new batch of coffee. When the empty volume in a particular storage tank is adequate to store an additional full batch of freshly brewed coffee, the operator receives a second visible indication from the control panel. The operator can control pumps and valves from the control panel and can read the temperature of the coffee in each of the storage tanks.

4. A gourmet hot beverage brewing and serving system comprising:
-
a plurality of brewing liners for brewing separate batches of brewed hot beverage, the liners being surrounded by a jacket of hot water; one or more insulated storage tanks, each storage tank for storing the beverages brewed in the liners at a serving temperature; first feed lines for transferring the brewed beverage from the liners to the storage tanks; one or more pumps in the first feed lines for facilitating transfer of beverage from the liners to the storage tanks, the pump or pumps being controlled by a timer pre-set for a duration of operation sufficient for transferring a full batch of beverage from a liner to a storage tank; serving taps for serving the beverages, the serving taps being remote from the brewing vessel and from the storage tanks; second feed lines for transferring the stored beverages from the storage tanks to the serving taps for dispensing the beverage; pumps in the second feed lines for pressurizing the beverages in the second feed lines so that a particular beverage may be dispensed by opening the tap connected to the second feed line, transferring the particular beverage; hot water lines connected to the water jacket surrounding the liners for circulating the hot water in proximity to the second feed lines and a pump for circulating the hot water through the hot water lines, such that the hot water lines transfer heat from the brewing water to the second feed lines to keep the beverages in the second feed lines at the serving temperature; thermal insulation surrounding the hot water lines and the second feed lines which are in proximity to each other; a first level indicator in each storage tank for indicating when the level of beverage in the tank is sufficiently low that a new batch of beverage for the tank should be brewed; a second level indicator in each storage tank for indicating when the tank is sufficiently empty that a new batch of brewed beverage may be transferred to the tank; and a temperature gauge in each storage tank for monitoring the temperature of the beverage in each tank and an external indicator connected to the gauge for reading the monitored temperature. - View Dependent Claims (5, 6, 7, 8)

9. A hot beverage brewing and serving system, comprising:
-
a brewing vessel for brewing separate batches of hot beverages at temperatures in a brewing temperature range; a plurality of insulated storage tanks for separately storing the separate batches of hot beverages at temperatures in a storage temperature range, so that a beverage may be simultaneously brewed in a particular brewing vessel and served from a particular storage tank, the storage temperature range being lower than the brewing temperature range; a serving tap remote from the brewing vessel and the plurality of storage tanks; first feed lines for carrying the beverages from the brewing vessel to the plurality of storage tanks; second feed lines for carrying the beverages from the plurality of storage tank to the serving tap; and means for maintaining the beverages in the second feed line at a serving temperature so that when the serving tap is operated after a period of inoperation, it serves the beverages at the serving temperature, the serving temperature being lower than the storage temperature range. - View Dependent Claims (10)

11. A hot bevrage brewing and serving system, comprising:
-
a plurality of brewing liners for brewing separate batches of brewed hot beverage, the liners being surrounded by a jacket of hot water; an insulated storage tank for storing a batch of a beverage brewed in the brewing vessel at a temperature in a storage temperature range so that the beverage from the same brewing vessel may be simultaneously brewed and served, the storage temperature range being lower than the brewing temperature range; a serving tap remote from the brewing vessel and storage tank; a first feed line for carrying the beverage from the brewing vessel to the storage tank; a second feed line for carrying the beverage from the storage tank to the serving tap for dispensing the hot beverage; and means for maintaining the beverage in the second feed line at a serving temperature by circulating water from the hot water jacket in proximity to the second feed line and back to the hot water jacket, whereby heat is exchanged to the second feed line. - View Dependent Claims (12, 13, 14, 15, 16, 17)
