Design and testing of small scale fish meat bone separator useful for fish processing

Abstract

The present study relates to the food processing machinery and, more specifically machine for producing boneless comminuted meat from raw fish fillet. This machine is of belt and drum type meat bone separator designed for small scale fish processing in a continuous mode. The basic principal involved in this machine is compression force. The electric geared motor consists of 1HP and the conveyor belt has a linear velocity of 19 to 22mmin(-1), which was sufficient to debone the fish effectively. During the meat bone separation trials an efficiency up to 75% on dressed fish weight basis was observed and with a capacity to separate 70kgh(-1) of meat from fish at the machine speed of 25rpm. During the trials, it was demonstrated that there was no significant change in the proximate composition of comminuted fish meat when compared to unprocessed fish meat. This design has a greater emphasis on hygiene, provision for cleaning-in-place (CIP) and gives cost effective need and reliability for small scale industries to produce fish meat in turn used for their value added products.
