METHOD FOR TREATING OIL SEED FLAKES PRIOR TO OIL EXTRACTION

摘要

The invention relates to a method according to which the oil seed is reduced in size and shaped to flakes by rolling before the oil seed is subjected to oil extraction. The flakes are fed to a transporting mixer to which water vapor and/or water are simultaneously added. They are transported in the mix er towards the outlet of the mixer with a dwelling time of 5 to 50 seconds. The flakes are removed from the mixer at a moisture content of 8 to 20 wt.-% and at temperatures in the range of 90 to 110 ~C. They are guided through a baki ng zone in which they are moved across heated floors at dwelling times of 15 to 50 minutes and at temperatures in the range of 90 to 110 ~C. The flakes are removed from the baking zones with a residual humidity which is at least hal f the humidity content of the flakes upon entrance in the baking zone. The flakes are guided through a drying and cooling zone in which they are converted to granules which are then subjected to oil extraction.
