Abstract
Objective: To solve the problems of low accuracy and low efficiency, high labor intensity and high production cost of fresh fruit manual sorting in China. Methods: A new dynamic weighing type fruit sorting machine was developed based on the fruit weight classification method. This machine operated by initially collecting the weight of fruit through a high-precision weighing unit. The data collected was then processed in conjunction with a signal processing module and a Programmable Logic Controller (PLC). The processed data controlled an actuator, specifically a launcher, to execute the sorting based on the fruit's weight. This machine was capable of continuously performing loading, weighing (diameter ≤126 mm). Results: When the separation efficiency was 18 327, 14 400, 10 473 PCS/h, the average separation accuracy was 95.31%, 96.12%, 97.13%, and the damage rate was 1.09%, 1.11%, 1.15%, respectively. Fruit sorting speed significantly affected the sorting accuracy, but had no significant effect on fruit damage rate. Conclusion: The new dynamic weighing type fruit sorting machine can effectively improve the efficiency of fruit sorting and reduce the damage to fruit under the premise of keeping the sorting accuracy >95%.
