Abstract
The belt and drum type meatbone separator was developed for smallscale fish processing and evaluated using Tilapia fish Oreochromis mossambicus in terms of capacity yield percentage yield bone content colour and power consumption It consists of a perforated drum 3 mm single phase electric motor speed reduction gear box and drive system The machine was evaluated using two food grade belt viz natural rubber Belt A35 shore and canvas belt Belt B65 shore for three drum speeds The machine capacity was in the range of 4559 to 6854 kg h−1 for belt A with a yield of 1148 1069 and 1066 kg and 4913 to 7813 kg h−1 for belt B with a yield of 1253 1312 and 1269 kg at drum speeds of 14 20 and 24 rpm respectively For belt A the highest yield 1148 kg was obtained at 14 rpm drum speed which was 6378 on dressed weight basis and for belt B the highest yield 1312 kg was obtained at 20 rpm drum speed which was 7289 on dressed weight basis The increased number of passes for meat recovery increased the chances of insertion of bone fragments into minced meat and decreased the colour values Lab The total energy consumption did not vary significantly
