Automated System for Sorting Blueberries by Size and Degree of Ripeness

According to the National Institute of Statistics and Informatics in the period of 2022, the production of blueberries was 42 thousand 40 tons, in which Peru has an export share of 59% destined for the United States. This work develops an automated system for the classification of blueberries by size and degree of maturity. For the simulation of the classification of blueberries by size from 10 mm to 14 mm and above, the bottleneck was determined by direct observation and then the mechanical system was programmed for the classification by size and then the colour detection was performed by HSV to classify blueberries over 10 mm by maturity, and then obtain the simulation in Factory IO and TIA PORTAL with connection to PLC S7-1200 1214 DC/DC/DC and a HMI TP700. Finally, the sorting proposal was implemented in which 100
^%
of the blueberries were recognised by means of the interactive HMI screen, being able to automatically sort and count them, which has a graphic environment for the operator to manipulate.
