  • Patent number: 4177722
    Abstract: An improvement in apparatus suitable for continuous separation of the flesh of fruit from its pits and seeds comprising a rotor 13, a screen 19 opposite the rotor wherein the rotor has radial arms provided with hammer heads 15 for working of the fruit for passage of the flesh through the screen and collection of the pits and skins on the screen. The improvement comprises the screen being rotatably mounted, drive means for the rotor and the screen for driving the rotor and screen at circumferential speeds differing by at least 10%, the hammer heads having striking surfaces inclined so as to form an acute angle with the axis of rotation in the radial projection of the striking surfaces onto the axis, and the rotor and screen being conical and disposed in nested relation. The heads can be so inclined that they advance the fruit along the surface of the screen.
