and Summary Crambe seed was dehulled and screw pressed to remove approximately two‐thirds of the oil, and then it was hexane‐extracted to remove the rest. The defatted meal was toasted in the presence of moisture to form a crisped meal possessing fast drainage characteristics required for continuous filtration. The crisped meal was slurried with four parts of water, filtered, and washed on a continuous pilot‐plant filter. Water washing removed about one‐fourth of the meal solids, which contained 92–96% of the glucosinolates. Estimated processing costs for water‐washing crambe meal are 22–23 dollars per ton of unwashed defatted meal, in addition to the cost of crushing the seed to oil and meal.
