Desarrollo de un sistema de control y monitoreo mediante recipe batch para un deshidratador a vapor de vegetales en la Facultad de Ciencias.

Abstract

A control and monitoring system with industrial recipes (RECIPE-BATCH) was developed for a vegetable steam dehydrator machine at the Science College. The heuristic method was applied for its development. First, the necessary parameters for dehydration were determined by analyzing the construction design of the equipment. Then, the functioning of the dehydrator machine was reestablished and evaluated in its technical status so that it could be repaired. The design of the control and monitoring system implementation contained the configuration and programming of the following: the Program Logic Control (PLC), Human Machine Interface (HMI), and a variable frequency drive; moreover, it was necessary to implement the communication via Ethernet between HMI and PLC. As the last step the technique called RECIPE-BATCH was used within HMI. As a consequence, the implementation of the control and monitoring system through RECIPE-BATCH reduced the dehydration time by 30 minutes. As a conclusion, the efficacy of the dehydration process before and after the implementation of the control and monitoring system increased by 6.66% due to the reduction of time in the process. This was accomplished since the dehydration temperature was stabilized and the dehydrator machine process was monitored. It is recommended to read the operator’s handbook before using the dehydrator machine, and when used in projects, it is suggested to use the same brand of machines and equipment to avoid interacting inconveniences.
