A method of brewing hot beverage with an electric hot beverage brewer () with a duty cycle modulated DC voltage dispense pump () with an inlet () connected to a de-aerator () and beneath a lower limit and an outlet () located above an upper limit the surface a hot water tank () is finely controlled by a high frequency pulse-width, modulated, square power input voltage (FIG.) with a duty cycle controlled in accordance with predetermined profiles stored within a controller () to selectively change the flow rate out of the pump onto a distribution dome () during a dispense period of a brew cycle to achieve optimum brewing of different types of beverage ingredients and varieties of the different types and to selectively change the spray pattern of hot water onto the ingredient () within the basket assembly () between vertical and acute angles including acute angles that pass hot water into a bypass gap ().

Beverage brewing method with variable speed dispense pump

An electric hot beverage brewer () with a duty cycle modulated DC voltage dispense pump () with an inlet () connected to a de-aerator () and beneath a lower limit and an outlet () located above an upper limit the surface a hot water tank () is finely controlled by a high frequency pulse-width, modulated, square power input voltage (FIG.) with a duty cycle controlled in accordance with predetermined profiles stored within a controller () to selectively change the flow rate out of the pump onto a distribution dome () during a dispense period of a brew cycle to achieve optimum brewing of different types of beverage ingredients and varieties of the different types and to selectively change the spray pattern of hot water onto the ingredient () within the basket assembly () between vertical and acute angles including acute angles that pass hot water into a bypass gap ().

Beverage brewer with dispense pump

An electrical, automatic hot beverage brewer () and method of brewing in which a removable brew chamber () has a drain hole () in the bottom fitted with a normally closed, pressure responsive brew chamber drain valve assembly () maintained in a normally closed position except when pressure against the drain valve () exceeds a preselected minimum pressure limit that is greater than the fluidic pressure applied by virtue of head pressure of a full load of hot water and a piston () is moved within the brew chamber to control the opening and closing of the drain valve () When the piston () moves downwardly toward the drain hole the air pressure of a pocket of air () above the beverage () in the brew chamber () is increased to open at the end of a seeping period when it is desired to rapidly expel freshly brewed beverage out the brew drain valve at a relatively rapid rate depending upon the total of the hydraulic pressure and the added pressure from the air pressure source to avoid the need to wait for the end of a drip period. The drain valve () automatically closes after the piston () is removed from the brew chamber () to enable removal of the brew chamber () from a brewer housing () without risks of hot beverage leaking out of the brew chamber ().
