In the factory the seeds are subjected to a number of processing steps prior to oil extraction. The oilseed is cleaned to remove trash, dirt, sand and metal pieces. The oilseed is then weighed for accurate control of oil and cake yield. The shell or seed coat is often removed from the oilseed kernel. This process is known as decortication and, as well as raising the oil content of the raw material entering the extraction machinery, it ensures a higher protein content in the oil-cake. Size reduction of the seed is sometimes followed by rolling to produce flakes which are then conditioned. During conditioning,

I did not succeed in activating Figures 1 and 2. Would it be possible to send these images by separate mail to may e-mail address: rainer.hoefer@cognis.com ?
