淡水鱼往复式去脏装置设计与工艺优化

为解决现有除脏装置易刮伤鱼腹的问题,设计了一种可往复作业的淡水鱼去脏设备。以鲤鱼为试验对象,建立以内脏去除程度和鱼腹完好程度为评价指标的去脏效果感官评定模型,分析除脏刀往复作业的起始位置、进给速度、进给量等工艺参数对去脏效果的影响,并对其工艺参数进行优化。结果表明:增大起始位置和进给量及减少进给速度有利于提高内脏去除程度,但造成鱼腹损伤的可能性也将增大。去脏工艺参数对去脏综合效果的影响顺序为进给速度>进给量>起始位置。当起始位置为27mm,进给速度为0.23m/s,进给量为64mm时,综合去脏效果最佳,内脏去除程度和鱼腹完整程度评分分别为4.65,4.82。

Design and process optimization of reciprocating decontaminating device for freshwater fish

In order to solve the problem that the fish belly is easy to scratch by the existing dirt-removing device,a kind of dirt-removing device for freshwater fish with reciprocating operation is designed.Taking carp as the test object,a sensory evaluation model of dirt-removing effect was established with visceral removal degree and fish belly integrity degree as evaluation indexes.The influences of process parameters such as starting position,feed speed and feed quantity of reciprocating operation of dirt-removing tool on dirt-removing effects were analyzed,and the process parameters were also optimized.By increasing the starting position and feeding rate,decreasing the feeding rate were beneficial to the improvement of the degree of internal organs removal,but the possibility of abdominal injury was increased.The order of influence of process parameters on the comprehensive effects of dirt-removal was operational speed>feed rate> starting point.When the starting position was 27 mm,the feed rate was 0.23 m/s,and the feed rate was 64 mm,the internal organs removal degree and the fish abdomen integrity degree score were 4.65 and 4.82,respectively.The comprehensive dirtremoval effect of this scheme was the best.
