链板式对虾开背装置的试验研究

Experimental study on the shrimp-cutting device formed by chain plate

针对国内对虾开背设备短缺状况,研制了一种链板式对虾开背装置。以环渤海的南美白对虾为研究对象,在该装置上分别以2种不同输送姿态、2种开背刀具类型、3种输送速度进行开背效果的比较试验。试验结果表明:对虾以背部朝下头朝前的姿态、刀片类型为有齿圆盘刀、输送转速为150mm/s时开背质量到达最佳。该研究可以为对虾机械开背设备的研制提供参考。

In terms of the shortage of shrimp-cutting device in our country, a shrimp-cutting device formed by chain plate was designed. Choosing the Penaeus vannamei arotmd Bohai Sea as the research objective of the study, the contrast experiments of cutting-quality with two dif- ferent conveying gestures, two different cutting tools, and three conveying speeds were carried out on this device. The results showed that： the best cutting-quality can be achieved when the shrimp was in back-down and head-forward posture, the blade type as toothed disc knife and the conveyor speed for 150 mm/s. This study can provide reference for the design of shrimp- cutting device.
