对辊上料对虾开背装置的设计与试验

Design and experiment on type of rollers feeding device of cutting opening at back of shrimp

设计一种对辊上料对虾开背装置,并分别进行有齿刀具和无齿刀具,正向旋转与逆向旋转以及刀具转速大小对开背效果和感官质量的比较试验。结果表明：采用无齿圆盘刀正向以350~400r/min切割时,对虾开背效果和感官质量最佳。该装置可确保对虾机械开背加工的质量稳定,提高对虾开背生产率,实用性强。

A cutting device for shrimp was designed,and a series of tests were carried out on efficiency of back open of shrimp and sense evaluation,between on gear knife and knife,post and reverse rotation,rotation speeds.The results showed that：by using the positive-free geared knife to cut shrimp when it came to 350~400r/min,the cutting result achieved best.The device is stable,efficiency and suiting practice.
