淡水鱼的连续式鱼鳞去除方法

为研究连续式鱼鳞的去除方法，以鲢鱼、鳊鱼、鲤鱼为试验对象，提出了一种以弹簧为主要去鳞结构的去鳞刷，并以弹簧外径、去鳞刷转速与去鳞刷直径等为主要因素，通过自制去鳞试验台研究了其对淡水鱼去鳞率和鱼体损伤的影响，表明弹簧外径、去鳞刷直径对淡水鱼去鳞率有显著影响，对鱼体损伤感官评价得分影响不显著，去鳞刷转速对去鳞率和鱼体损伤感官评价得分均有极显著影响。不同种鱼，其各自适宜的弹簧外径、去鳞刷直径与去鳞刷直径有所不同。确定了白鲢去鳞时弹簧外径、去鳞刷转速、去鳞刷直径的最优参数组合，即弹簧外径21 mm、去鳞刷转速1 120 r/min、去鳞刷直径90 mm。该研究可为连续式去鱼鳞机的研制提供依据。

Continuous scaling method for freshwater fish

To study continuous scaling method for freshwater fish, sliver carp, bream and carp were taken as test objects, and a scaling brush was proposed which used springs as the main scaling structure. Then the influence of three factors on scaling ratio and body injury of freshwater fish was studied by using a scaling test equipment made by authors, including spring external diameter, brush rotating speed, brush diameter. It showed that spring external diameter and brush diameter had a significant influence on scaling ratio and had no significant influence on fish body injury. However, the brush rotating speed had significant influence both on scaling ratio and fish body injury of freshwater fish. Different fishes needed different spring external diameter, brush diameter and brush rotating speed while be scaled. Then the optimal combination of the key factors were determined by the test, which were spring external diameter 21 mm, brush rotating speed 1120r/min and brush diameter 90 mm. This study can provide reference for the design of continuous scaling equipment for freshwater fish.
