淡水鱼连续式去头尾装置的研制

Design of continuous device for cutting head and tail of freshwater fish

为了实现淡水鱼的高效去头尾加工功能,研制一种由间歇输送系统、刀具夹具驱动系统、控制系统等组成的淡水鱼连续式去头尾装置。该装置配套功率2.3kW,其中间歇输送系统电机1.5kW,刀具夹具驱动系统空气压缩机0.75kW,控制系统等0.05kW。以(0.400±0.100)kg鳊鱼,(1.200±0.300)kg草鱼为研究对象,进行装置加工效果评价试验。试验结果表明,去头尾装置加工鳊鱼得率为82.10%,草鱼得率为76.30%,加工鳊鱼感官评分为0.81,加工草鱼感官评分为0.79,加工鳊鱼成功率为90.00%,加工草鱼成功率为80.00%,加工效率可达1 350条/h。

In order to realize the efficient processing function of removing head and tail of freshwater fish,a continuous device for cutting head and tail of freshwater fish was designed.The device consisted of intermittent feeding system,tool and fixture driving system,control system and so on.The rated power of the device was 2.3 kW,including a1.5 kW system for the intermittent feeding,a 0.75 kW for the drive system of cutter fixture and a 0.05 kW control system.The test of processing effect of the device were conducted using（0.400±0.100）kg Parabramis pekinensis and（1.200±0.300）kg Ctenopharyngodon idellus.The research showed that using the device to process P.pekinensis and C.idellus,the rate of meat-getting is 82.1% and 76.3%,sensory score was 0.81 and 0.79,the success rate was 90.00% and 80.00%,respectively,with the processing efficiency of up to 1 350 h-1.
