ABSTRACT:
Fish are cooked and pressed. Oil may be separated from the first press liquor and recovered. The first press liquor remainder is concentrated to about 30-50 percent solids and intimately mixed with the first press cake and reabsorbed thereinto. Then the resulting mixture is pressed again and dried to produce a fish meal product containing substantially all of the solids originally present in the fish, but minus most of the water and optionally minus some of the oil originally present. Press waters, pumping waters and the like are recycled to minimize environmental effect. A flow control means is preferably used to ensure that sufficient concentrated first press liquor is added back to the first press cake to maintain a reasonably steady state material balance in the system.
