Diseño de un sistema de control automático para su implementación en el evaporador de simple efecto con serpentín del laboratorio de procesos industriales de la Facultad de Ciencias.

Abstract

The design and implementation of an automatic control system for the evaporator coil single action that is in the laboratory of industrial processes of the Faculty of Sciences was held. For them generate mathematical model of evaporation process using actual data from the evaporator and the raw material used, so you can decide what kind of automation process would be implemented. Temperature, frequency of the electric motor and the time per step and total process: in this way the process variables were automated. It was used as a PLC controller, which controls the logic programming process. To measure an RTD temperature sensor, which is connected to an analog input module annexed to the PLC used. To control the frequency of the electric motor an inverter was used from 0-60 Hrz, which effects mechanical speed reducer represents 30 rpm. HMI touch screen and remote panel via wireless connection: to provide greater ease of entry and monitoring process variables two-way implemented. The latter variable is the time controlled process, which is divided into two stages or evaporation cooking process and the cooling time. To control the flow of steam and water supply valves are used, they closed to failure. They simply allow material flow or closed. The objective of the design and implementation was to expand the gamma of foodstuffs to be developed with this team and facilitate the handling of the process.
