Desarrollo de una secadora automática para cacao de alta capacidad mediante flujo de aire caliente

Abstract

The present project focuses on the development of an automatic dryer for high-capacity cocoa using hot air flow. Its main objective is to design and build an automated dryer with a capacity of 500 kg of cocoa, using LPG as fuel for heat transfer. The importance of this machine lies in the crucial role of cocoa in the Ecuadorian economy, aiming to optimize the drying process, reduce the risk of mold due to high humidity, and improve product quality. The document includes a theoretical framework that explores the drying of fruits, different types of dryers, principles of automation, and components such as motors and sensors. It also describes the methodology used for the design and construction of the machine, as well as the development of a user manual for its safe operation. Finally, conclusions are presented that highlight the improvement in cocoa quality, time and resource savings, and recommendations for the maintenance and operation of the dryer, emphasizing the importance of staff training and the control of temperature and humidity during the drying process.
