ABSTRACT:
A continuous automatic beverage brewer is provided for producing a brewed liquid beverage, such as coffee, in any desired pre-selectable amount. The brewer includes means for supplying a liquid, such as heated water, and a solid particulate beverage ingredient, such as ground coffee, to a mixing duct through which the mixture passes for a time sufficient to effect proper brewing. A moving filter intercepts the mixing duct so that a fresh surface of the filter is continually presented to the mixture of brewed beverage and spent solid residue of the beverage ingredient to thereby achieve effective filtering. Preferably the moving filter comprises a continuous belt of filter material, the surface of which moves continually past the output of the mixing duct so as to continually remove the spent solid residue. When continuously brewing a hot liquid beverage (e.g. coffee) means are provided for maintaining the mixture of the liquid and the beverage ingredient at the desired brewing temperature during passage of the mixture through the mixing duct, preferably by disposing the mixing duct within a reservoir containing the heated liquid therein. Selectively controllable timing means are provided for controlling the supply of heated liquid and solid beverage ingredient to the mixing duct during pre-selectable intervals to produce any desired quantity of brewed beverage, and also for controlling the operation of the filter belt to cause its surface to move past the outlet of the mixing duct when the brewed beverage is being supplied therefrom.
