Implementación de la tecnología industria 4.0 mediante un controlador lógico para un proceso de secado rotativo en el laboratorio de operaciones unitarias.

The Industrial Engineering Department of the Universidad Nacional de Chimborazo, the students have a laboratory of “Operaciones Unitarias” for the realization of practices, where there is a pilot rotary dryer, which due to use ceased to be operational, also taking into account that the control system is based on local wired logic is very rigid with respect to the rotation of the drying cabinet and air flow, The temperature control is based on a thermocouple whose main problem is the thermal inertia of the resistance causing a significant error in their values, in the development of practices has the disadvantage of not having data acquisition, so you must use other equipment for the study of the process. Due to this, the main objective of this study was to implement the Industry 4.0 (I 4.0) technology due to the facilities it provides both in the drying process and data acquisition for its study, starting from a programmable logic controller (PLC) that allows the regulation of variables (temperature, flow and rotation of the drying booth) according to the needs of the grain drying process, on the other hand for data management a server (Raspberry Pi) connected to the internet was implemented that allows data acquisition in real time and anywhere. In order to demonstrate the impact of the changes made in the equipment and the improvement in the process, historical data of tests carried out on the equipment were used by means of statistical tools (HJ-Biplot and Partial Triadic Analysis), determining that the equipment intervened with I 4. 0 technology significantly reduced the final percentage of humidity, as well as the drying times, and the values of the dry bulb temperature (Tbs) and wet bulb temperature (Thb) indicators are highly correlated, thus demonstrating that the 4.0 equipment behaves in a stable manner. The t-student test was also applied, showing that the means of the moisture percentage are different (p-value = 0.000) and the means of the drying times are also different (p-value = 0.02).
