Abstract: An extraction assembly for use in an automatic brewer. The extraction assembly controllably extracts espresso beverage from a quantity of brewing substance. A brew chamber of the extraction assembly is removable for exchange with another brew chamber of different brew volume, having enhanced structures, or for replacement and repair. A heating element may be in close proximity to the brew chamber. Heat from the heating element can be brought directly to the area in which the coffee is brewed to help maintain a more consistent, tighter tolerance temperature and faster recovery between brew cycles.

Abstract: The present disclosure includes an extraction assembly for use in an automatic espresso brewer. The extraction assembly includes components and methods for controllably extracting espresso beverage from a quantity of brewing substance. The components, assemblies, and methods facilitate improved control and operation of the extraction assembly and improve the reliability of the extraction assembly. The brewing substance is compacted between a pair of opposing pistons. Compacting force is monitored through at least one sensor carried on the extraction assembly to provide a signal to a controller. A predetermined compacting force may be programmed into the system for all brewing cycles or dependent upon the brewing substance used. The pair of pistons operates relative to a brew chamber for use in the espresso extraction process. The pistons provide compacting force and boundaries within the chamber and facilitate removal of a spent brewing substance puck at the end of the brewing cycle.
