Cocoa Bean Dryer and Cleaner Devise : A Microcontroller Experiment

Cleaning and drying cocoa beans are generally done manually by farmers. The manual cleaning process takes a long time, the pulp reduction is not optimal. In contrast, using sunlight time when it in rainy season. This causes to be moldy have low sale value. equipment made factory, two machines separately hardly affordable Based on these problems, microcontroller-based bean dryer (de pulper) was designed with single container so that both processes could carried out just one machine. To elaborate this system, fermented shed rotating cylinder. comparison, heat source, soil moisture sensor detect content of beans, DS18B20 temperatures container, cylindrical rotated an A.C. motor. experiment results, 10 minutes clean from pulp. 5 hours, minutes, hours 40 dry maximum 7%. A can speed up compared proposed tool study carry more efficient capacity better than conventional tool.
