For the purpose of admixing hot water with a water soluble extract the end of a motor driven beating shaft is immersed in and removed from the water contained in a cup during that portion of the cycle of operation when the beating shaft is not rotating. The beating shaft is spring biased on a pivotal arm to a normally raised position. A thermostat controls the heating of the water which is discharged from a tank by means of a spigot. |
