Implementación de un sistema de control de los parámetros que intervienen en un secador de Cacao Rectangular

The development of this technological proposal seeks to solve the need to have a control of the systems that interact in a cocoa drying process, for which an analysis of devices that allow the different factors to be controlled was carried out, in turn with this it is sought that the process is done in the shortest possible time. The first main factor is the air flow for which after different measurements it was decided to use a MAF sensor; 6 RTD PT100 are used to obtain the data for the respective temperature control which in the system is the key factor because if the parameter is wrong the product will lose the fundamental characteristics required to be marketed and stored. For weight measurement, three "S" load cells are used, which have a maximum capacity of 100 kg, in order to obtain the value in real time, to observe the loss of moisture in the process. Subsequently, a microcontroller is used to collect the parameters, which allows the data acquired to have an ideal processing in order to achieve an optimal control of the process that is efficient in terms of energy consumption. For the visualization of the behavior and data display, a Nextion screen is used, which due to its characteristics has the capacity to implement functions that make the interface have a correct performance. The error of the data obtained in the system are 0.43% in temperature, 2.95% in weight and 4.74% in flow; additionally, making a comparison between artisanal processes, the LPG consumption is 10.51 kg per quintal, while the controlled process uses 1.5 kg per quintal.
