A laboratory-scale pilot plant is beneath construction in order that problems concerned in laptop control of vegetable oil processing may be studied. Unit operations planned for this mini-refinery are continuous alkali-refining, bleaching, hydrogenating, and deodorizing. The alkali-refining step, just like the Swedish enithcourse of, is already in operation. Transducers for oil coloration, sodium content material, and free fatty acid concentration have been constructed; each crude and refined oils are being analyzed. Provision has been made to perform the identical analyses at later phases of processing on the bleached, hydrogenated, and deodorized oils. Beneath Part I of implementing computer control, electronic alerts from the analytical transducers are despatched to the computer through applicable interfacing hardware, and results are returned to the operator through Teletype. Phase II will involve monitoring by the pc however with resolution making and directions to an operator, and Section III will involve losing the loop,that’s, having the pc immediately management the method. Development of transducers, software and hardware akin to is described here for the mini-refinery, should facilitate subsequent implementation of pc management on a plant scale.
