ABSTRACT:
A portable fish scaler includes an open top tank with a drum unit rotably mounted to the top of the end walls. A motor is directly coupled to drive the drum, either with a small AC motor having an integrated gear reducer or a small 12 volt DC motor directly coupled to the shaft to slowly rotate the drum. Bearing support units on the end walls permit the drum shaft to be directly inserted and removed. One bearing is a U-shaped block of a low friction plastic and the other is a telescopic plastic bearing. The drum shaft rests in the U-shaped bearing and telescopes into the coupling bearing. The drum is formed from a flat plate which has inward scaling projections formed by punching the metal to form each projection with a jagged inner edge. The plate is rolled to form a cylinder. A smaller second drum floats on the first drum shaft. The second drum has outward scaling projections and may be formed from two flat plates secured back-to-back and with the centers curved outwardly. The projections in the outer drum are formed in different groups, one of which has larger diameter openings for removal of larger scales. A small inner drum with cleaning projections floats on the shaft to further remove scales.
