US Patent 10455972 Beverage brewer with brewing rotation

A coffee maker includes an injection needle producing a dispersed spray and a rotating brewing chamber. The brewing chamber may include rollers for rotating a brewing cartridge and a centered extraction needle, or may include a rotating cradle including one or more offset extraction needles. The injection needle includes radially oriented ports providing the dispersed spray into the cartridge interior. As the cartridge is rotated, the dispersed spray prevents or reduces the formation of channels or clumping of the brewing material thus providing better extraction of brewed beverage from the brewing material.
