Abstract: A fruit gripper head assembly for use in a machine for pitting fruits of the drupe type includes a support structure receivable onto a pitting machine, a plurality of gripper arms spaced about the central axis of the assembly and mounted on the support structure for pivotal movement toward and away from the central axis, and fluid pressure operated actuating apparatus operatively connected to the gripper arm and to the support structure for urging pivotal movement of the arms toward the central axis upon introduction of pressurized fluid behind that actuating apparatus to provide for pivotal movement of the arms to grip fruit to be pitted.

Abstract: Apparatus is disclosed for loosening the skin of moisture bearing fruit which have been heated at a first pressure to a predetermined temperature. This includes structure for introducing fruit into the apparatus, structure for holding the fruit and moving it along a predetermined path, equipment positioned along the path for reducing the pressure surrounding the fruit sufficiently below the first pressure to cause expansion of the moisture inside the skin of the fruit to loosen that skin, and finally structure for discharging the fruit from the holding and moving equipment at generally ambient pressure.

Abstract: Apparatus is disclosed for moving and thermally conditioning generally cylindrical containers in which the structure provides for movement of the containers about their axes and provides for a predetermined heat flow relative to the containers to change the temperature of the containers by a predetermined amount.

Abstract: Methods are described for separating the pulp from the skin of fruit, such as tomatoes, in which each fruit is gripped and transported by mechanism along a continuously circular path, a cut to the skin of the fruit is produced by cutting device adjacent the path and the pulp is urged away from the gripping and transporting apparatus at a pulp discharge position while the skin remains gripped by that apparatus to separate the pulp from the skin.

Abstract: A fruit peeling machine comprising improved fruit peeling rollers in which at least one of each pair of rollers is provided with axially extending ribs projecting radially outwardly from the roller sufficiently to cause the fruit carried thereupon contact substantially only the outer portions of such ribs without substantial contact between the fruit and the portions of the rollers intermediate adjacent said axially extending ribs.

Abstract: Apparatus and methods are described for separating the pulp from the skin of fruit, such as tomatoes, in which each fruit is gripped and transported by mechanism along a predetermined path, a cut to the skin of the fruit is produced by cutting device adjacent the path and the pulp is urged away from the gripping and transporting apparatus at a pulp discharge position while the skin remains gripped by that apparatus to separate the pulp from the skin.
