本文通过分析扇贝加工各个阶段工作,结合国内外扇贝加工机械的发展现状,设计出集扇贝清洗和分级工作于一体的加工装置。该装置根据扇贝贝壳结构特点和生理特性设计出双排毛刷辊清洗方式,根据扇贝的外形尺寸特点设计出对辊式扇贝分级方式,并将清洗与分级工作通过食品输送带连接,实现清洗分级一次性完成。清洗毛刷辊两排运动速度不同,上排毛刷辊转速为200 r/min,下排布置在两侧毛刷辊转速为120 r/min,下排布置在中间毛刷辊转速为360 r/min,并通过与高速气流配合工作,加强了清洗效果。清洗后的扇贝经过食品输送带的传送进入到分级部分,采用螺旋对辊进行分级,分级辊转速为67 r/min,分级辊可改变直径、倾角可调节,提高分级的准确性、可靠性。扇贝清洗分级一体装置的设计减少扇贝加工中劳动量的投入,节约扇贝加工时间,保证扇贝鲜活程度,为扇贝加工行业提供可靠的加工机具。

[Abstract]
The processing device that integrates scallop cleaning and grading work is designed by analyzing the various stages of scallop processing and combining the development status of domestic and foreign scallop processing machinery. A double-row brush roller cleaning method was employed according to the structural and physiological characteristics of scallop shells, and a double-roller scallop grading device was designed according to the scallop shape and size characteristics, and the cleaning and grad ing work were connected through the food conveyor belt to achieve cleaning and grading simultaneously. The two rows of cleaning brush rollers move at different speeds, the upper row of brush rollers has a speed of 200 r/min, the speed of the brush roller in the bottom row is 120 r/min on both sides, and the speed of the brush roller in the middle is 360 r/min, the cleaning effect is enhanced by working with high-speed airflow. The cleaned scallops are conveyed by the food conveyor belt to the grading part, the spiral roller is used for grading, the speed of the grading roller is 67 r/min. The diameter and inclination can be adjusted to improve the accuracy and reliability of classification. The device integrating scallop cleaning and grading reduces the labor input in the scallop processing, saves the scallop processing time, ensures the freshness of the scallop, and provides reliable processing tools for the scallop processing industry.
