Abstract

Abstract Food-coring apparatus for use in the coring of foods, such as cauliflower, includes a movable flight conveyor having foodholding pockets therein and an air piston operated retractable head having an air-powered coring bit and a cover which is rapidly moved into coring position by the air piston. An actuating eccentric is mounted on the conveyor drive for actuating air to the piston and bit to move the retractable head toward the food to engage the food with the cover and coring bit. The depth to which the food is cored is controlled independently of the position of the conveyor flights by a switch responsive to the movement of the retractable head to retract the bit and cover and secure the air to the coring bit.
