Máquina clasificadora automática de polen de abejas

Abstract

This project designed and assembled an automated machine that classifies, separates, and dries pollen collected by bees, aiming to improve the efficiency of beekeeping processes in Colombia. The initiative arose in response to the challenges faced by small beekeepers in handling pollen, particularly in terms of manual classification, processing time, and contamination risks. The system integrates electronic automation technologies such as DC motors, PWM-controlled fans, heating elements, and an Omron E5CN PID controller to maintain the appropriate temperature during pollen drying. The machine is designed to classify pollen according to its texture (powder, semi-powder, and granules), thus ensuring the quality of the final product and optimizing production times. To evaluate the system's performance and efficiency, an experimental procedure was defined based on the following steps: 1. Controlled initial load: One pound of unsorted pollen (454 grams) was introduced into the system. 2. Processing time measurement: The total time required by the machine to complete the sorting and drying cycle was recorded. 3. Efficiency calculation: Based on the collected data, the overall efficiency of the system was calculated by measuring the ratio of sorted pollen to the total pollen input. 4. Production rate determination: The machine's capacity was estimated in grams per minute, useful for projecting performance under real-life operating conditions. The project was carried out as an internship in collaboration with SENA, lasting three months and with a total of 384 hours of dedication per student. The total cost was $19,271,770 COP, with in-kind contributions from SENA.
