present invention is designed for use in connection with a grape dejuicing machine having a cylindrical barrel formed with a plurality of perforations therethrough and an expressor screw formed with helical flights rotatable therein for squeezing grapes fed into said barrel to extract their juice conventionally and as here shown the barrel 12 is inclined and at its lower end 16 opens upwardly to receive grapes 17 from a hopper 18 the upper outlet end 19 of the barrel 12 is provided with a swinging door 21 movable by a hydraulic piston 22 against the solid remains 23 so as to create back pressure against movement of the grapes 17 through the barrel 12 causing the grapes to be pressed gently at first and then harder and harder as they progress through the barrel 12 to the outlet end 19 a suitable motor drive 24 rotates the helical screw expressor 14 in accordance with the present invention a plurality of substantially parallel flattened juice receiving drip pans are carried on support means 27 formed for supporting the pans 26 in inclined generally parallel and vertically spaced relation underneath the portions of the barrel 12 from which juice emanates during squeezing of the grapes 17 a plurality of open top receiving troughs 28 are mounted to extend transversely of the barrel 12 in side by side relation beneath the lower ends of the pans 26 to receive juice therefrom at least one of the pans 26a being slidably adjustable on the support means 27 so as to receive 34 first pressing 34 juice from said barrel up to a desired station therealong and to deflect such juice into one of the receiving troughs 28a a flattened trough 29 extends.
