Description: Wheat, the predominant feedstock for ethanol production in Canada may be debranned prior to the milling, fermentation and downstream processes. Experiments were carried out using two the Satake mill and tangential abrasive dehulling device (TADD) to remove the bran layer of wheat to optimize the debranning process. Two hundred gram samples of wheat grains were debranned in the Satake mill at grit sizes of 30, 36 and 40, retention time of 30, 60 and 90 s and rotational speed of 1215, 1412 and 1515 rpm or in the TADD at grit sizes of 30, 36, 50 and 80, retention time of 2, 3, 4 and 5 min and rotational speed of 900 rpm. The statistical analysis indicated that rotational speed and retention time were the most significant factors in Satake mill and grit size and retention time affected debranning efficiency in TADD. Using abrasive rollers of higher grit size (fine grit) resulted in a decrease in the percentage removal of bran whereas long retention time caused a high amount of bran to be removed. This, in turn, results in an undesirable loss in starch content of the kernel. . The results indicate that rotation speed of 1412 rpm, 40 grit size and 60 s retention time are the optimum condition for bran production for the Satake mill. Similarly, 900 rpm rotation speed, 50 grit size and 300 s retention time are the optimum conditions for the TADD mill though bran obtained from debranning in TADD was low. Based upon starch separation efficiency, the optimized conditions for the Satake was more desirable compared to TADD.
