PURPOSE:Elastic rollers with rough surfaces are arranged between a couple of frames so that the peripheral speed becomes different between adjacent rollers to form the titled device of high efficiency. CONSTITUTION:Groups M of rollers 2 which are composed of an elastic material with pores on its surface and have rough peripheral surfaces a are arranged between the frames 1, 1' so that they run ascending as they advance (7 is the inclined plates set between rollers different in their height. Further, the peripheral speed of each roller 2 is changed by altering the size of the sprocket 4 fitted to the shaft 3 so that the transfer of the fruits are accelerated gradually toward the transfer direction (5 is driving chain and 6 is wheel). The peripheral speed of each roller may be decreased gradually or may be repetition of acceleration and deceleration.
