Abstract: A frame structure having a pre-dewatering unit fixedly mounted thereon and a final-dewatering and inspection table unit movably mounted thereon. The pre-dewatering unit includes a vertically extending receiving compartment through which the mixture of water and vegetables passes upwardly from bottom to top and a pre-dewatering chute adapted to receive the mixture flowing over the top of the receiving chamber. The pre-dewatering chute includes an upper chamber and a lower chamber separated by a screen member. The screen member is positioned at an angle to the horizontal so that the solid material in the mixture will pass over the top surface of the screen member and a substantial portion of the liquid material will pass through the screen member into the lower chamber. The final-dewatering and inspection table unit includes a final-dewatering section and an inspection table section, both of which are vibrated by a suitable vibratory means.
