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.
Claims7
A submersion brewing apparatus comprising:
- a vapor and liquid tight extraction vessel comprising an upper section and a lower section;
- a sieve basket adapted to hold extraction source media and completely contained in the lower section of the extraction vessel,
- a dispensing line in fluid communication with the lower section of the extraction vessel;
- a boiler vessel in fluid communication with the upper and lower sections of the extraction vessel adapted to provide a heated extraction liquid and a pressurized vapor into the extraction vessel;
- and
- an operational program to control an array of sensors and valves adapted to control the flow of the pressurized vapor and extraction liquid from the boiler vessel into the extraction vessel to apply positive vapor pressure above the extraction liquid in the extraction vessel to forcibly move the extraction liquid across the extraction source media and sieve basket and out the dispensing line.
The submersion brewing apparatus of claim l wherein the sieve basket comprises a support structure for a media filter to prevent extraction source media from passing through the sieve basket.
