A device for extracting oil from the Peel of citrus fruits, not spherical, whole

摘要

Parallel horizontal toothed rolls form bights therebetween for reception of non-spherical citrus fruit such as lemons. A body of liquid submerges the toothed rolls so that puncturing of the peel of the fruit takes place below the liquid level. Groups of the toothed rolls are turned in the same direction but at progressively slower speeds. Adjacent toothed rolls are reciprocated axially in opposite directions to change the orientation of the fruit with respect to the toothed rolls. The rolls may be pushed and pulled from one side of the machine through a cam operated device or they may be pushed from both ends by mechanism on opposite sides of the machine.
