A food processor incorporates an electronic motor control and display. Times relevant to the operation of the food processor are displayed for reference by the user. A user can select a food processing cycle duration, in which case the display is operated in a count-down mode. If no duration is selected, the display is operated in a count-up mode. Measured motor speed is used by a microprocessor based motor control circuit to regulate power delivered to the drive motor. A programmed auto pulse function delivers power to the drive motor in an on off pattern, freeing the user's hands. A safety switch is arranged to sense the presence or absence of the food pusher in the chute. Operation of the food processor drive motor is paused until the food pusher is replaced in the chute. The food processor is provided with a high-speed function. |
