RECIRCULATION COFFEE BREWER

摘要

Coffee or tea brewing and dispensing apparatus wherein hot water and fresh beverage grounds are delivered into an open top receptacle and the brewed beverage drawn from the bottom thereof through a filter comprising wet coffee grounds supported on a foraminous screen by a suction pump in a recirculation and delivery line coupled to the bottom of the receptacle. A discharge spout connected to the line downstream of the pump is mounted for shifting movement from a position for returning brewed beverage back into the receptacle to an alternate position for delivering the beverage to a dispensing station. The receptacle is selectively movable away from the screen through a displacement to permit removal of grounds therefrom by a scraper blade shiftable across the upper face of the screen. A series of cams and associated followers driven by a single motor sequentially operate the components of the apparatus by controlling introduction of water and fresh grounds into the receptacle, effecting predetermined recirculation of the brewed beverage, then diverting the spout to the delivery position thereof and finally elevating the receptacle and causing the scraper to remove grounds from the screen.
