at a uniform head pressure for the remainder of the open portion of the control period the volume of the cavity 59 is of course only a small portion of the total volume of beverage to be brewed and of the volume of the brewed beverage container 28 preferably in the case of making several gallons of brewed beverage per brew cycle the uniform flow dispenser head has a diameter and the cylindrical side wall 60 has a height to provide the a volume of only a fraction of a gallon the inlet opening 66 and the head pressure provides an initial flow rate into the uniform dispenser head 38 to fill the cavity 59 within less than a second at the start of each control period thereafter once the cavity 59 is filled back pressure is encountered and the flow rate is determined by the number and size of the plurality of dispenser holes 65 the greater the number of and the smaller the size of the dispenser holes the more uniform will be the flow across the top surface of the ingredient layer however the inventor has determined that in order to minimize clogging problems the dispenser holes 65 should not be too small on the other hand the inventor has determined in order to obtain optimum control over.
