is twenty seven percent or less is supplied to a fluidized bed reactor of the sort shown in either fig1 or fig2 the dryer is then operated at a temperature such that the wet bulb temperature of the exit gases is above 54 u00b0 c and preferably 60 u00b0 95 u00b0 c because the moisture level of the starch is twenty seven percent or below the elevated temperatures used in the fluidized dryer serve to minimize operating costs while increasing dryer capacity without any significant damage to the starch in the preferred practice of the invention the starch to be dried is a cake obtained from centrifuging in the conventional starch wet milling process and contains from about twenty eight to forty five percent moisture by weight that wet starch is thus blended with starch obtained as produced from the dryer by way of a recycle of a portion of the dried starch product the dried starch recovered as produced from the dryer generally has a moisture content ranging from about two to nineteen percent moisture by weight depending somewhat on the desired use for the dried starch referring to fig1 the dried starch can be removed from the discharge port 36 and a portion recovered from line 54 another portion is recycled via line 56 for passage to a blender 58 to which centrifuge cake is supplied by line 60 to make up the supply of starch having a moisture.
