A blender control apparatus and method includes monitoring the operation of a blender motor as a measure of monitoring the quality and results of blending. By connecting a feedback sensor to the motor, it is possible to determine whether a blend process is complete. It is also possible to identify when cavitation is occurring or about to occur. In another aspect, the blender controls are directed to an improved method for portion blending. The method includes a two-step query to the user to determine both a predetermined blender cycle and the number of portions to be blended.

1. A method of controlling blender operation to produce a consistent, blended material comprising the steps of: providing: (a) a blender assembly comprising a blender motor operatively connected to a cutter assembly, wherein the cutter assembly is mounted in a blender jar for blending material placed within the jar;(b) an energy control switch that activates and controls the amount of energy delivered to the motor during operation of the motor; and(c) a feedback sensor electrically connected to the energy control switch,wherein the feedback sensor is adapted to detect an attribute associated with the operation of the motor and send a signal to the energy control switch based on the attribute detected;adding material to the blender jar;activating the blender motor;recording the signal from the feedback sensor to the energy control switch at predetermined time intervals and comparing the signals over time; anddeactivating the blender motor when a predetermined relationship is found in the comparison of signals recorded from the feedback sensor. 2. A method as described in claim 1, wherein the predetermined relationship is substantial identicality in the signal recorded from feedback sensor. 3. A method of reducing cavitation in a blender comprising the steps of: providing:(a) a blender assembly comprising a blender motor operatively connected to a cutter assembly, wherein the cutter assembly is mounted in a blender for blending material placed within the jar;(b) an energy control switch that activates and controls the amount of energy delivered to the motor during operation of the motor; and(c) a feedback processor comprising a feedback sensor electrically connected to the energy control switch, wherein the feedback sensor is adapted to detect an attribute with the operation of the motor and send a signal to the energy control switch based on the attribute detected;adding material into the blender jar;activating the blender motor;recording the signal from the feedback sensor at predetermined time intervals;analyzing the signal over time and determining when cavitation is occurring or about to occur;when cavitation is occurring or about to occur, sending a signal to the energy control switch to reduce the power to the blender motor for a predetermined time period;increasing the energy to the blender motor at the end of the predetermined time period.
