ABSTRACT:
A spent flake drainer-conveyor for transferring spent flakes from a solvent extraction apparatus to a desolventizer-toaster apparatus, having a closed vapor tight housing extending from the desolventizer-toaster to the solvent extraction apparatus. A drainage section is formed in the housing and contains a screen section through which the flakes are moved. A vacuum source is attached to the drainage section causing a pressure differential across the screen in order to assist in separation of solvent from the flakes as they pass through the screen. A motor torque monitoring device is associated with the drive motor of the picker in the solvent extraction apparatus to provide an indication of the level of flakes in the trough portion of the solvent extraction apparatus. A variable speed drive and a motor speed control associated with the torque monitoring equipment controls the rate of movement of the conveyor so that the level of flakes in the trough portion of the solvent extraction apparatus can be maintained at a desired level through adjusting the rate of movement of the conveyor.
