Abstract
The present inventive concept consists of a logic controlled submersion brewing device that operates reliably with minimal user interaction. The brewer employs a submersion brewing technique to ensure a uniform extraction of beverage from solid extraction media. The device may be programmable to start on a timer. Parameters of the brew program may be customizable including serving size and extraction settings. The device will use vapor pressure to forcibly move beverage liquid across a sieve thereby separating the liquid from spent extraction media. Reliability and repeatability of the separation procedure is enhanced using a novel method of pressure control.
Claims15
A method for a submersion brewing apparatus comprising:
- providing a boiler vessel for heating extraction liquid to generate a heated extraction liquid and heating vapor to generate a pressurized vapor;
- providing a vapor and liquid tight extraction vessel with a sieve basket for holding extraction source media, the extraction vessel having an upper section and a lower section each in fluid communication with the boiler vessel, the sieve basket being completely contained in the lower section, the extraction vessel adapted to receive the heated extraction liquid and the pressurized vapor from the boiler vessel;
- and
- providing a dispensing line in fluid communication with the lower section;
- and
- providing an operational program to read sensor data and to control valves, the operational program for controlling flow of the heated extraction liquid and the pressurized vapor from the boiler vessel into the extraction vessel to apply positive vapor pressure above the heated extraction liquid in the extraction vessel to forcibly move the heated extraction liquid across the extraction source media in the sieve basket and out the dispensing line.
