Agro-industrial companies such as Agro-empaques SAFCO S.A.C., carry out fumigation processes on grapes before packing them as a standard procedure to ensure they maintain postharvest quality during transportation. Most commonly, these companies apply sulfur dioxide (SO2) directly to crates of grapes placed in gasification chambers. However, due to its rudimentary control system and inadequate manual operation, the company faces cost overruns and economic losses. This project proposes the development of an automatic control and monitoring system for the fumigation process of grapes with SO2. The system includes various control subsystems that allow and guarantee the automatic operation of the entire fumigation process. In the injection stage, the change of state of SO2 (liquid to gaseous) is guaranteed by means of pressure and temperature control; on the other hand, the control of the dose required for the fumigation process is guaranteed by means of a totalized mass flow control. In the treatment and evacuation stage, a concentration-time control was established that determines the total fumigation time to which the grapes will be subjected during the process. The implemented system complies with national and international engineering standards and quality standards required by the company. Additionally, it is composed of different peripherals such as control panel, power panel, instrumentation equipment and communication network. These peripherals, as a whole, allow the control and supervision throughout the fumigation process.
