In the pasteurization process, the microorganisms that are used for the fermentation and rotting of bier are mainly eliminated by high temperatures. This project is about a study of feasibility for the implementation, cost analysis and the rent of the automation for the process of equipment for flash pasteurization in a bier industry. The main point of this job is to obtain the advantages in costs, production and mainly in the quality of the final product of the pasteurization working with an automation process. For this, we have considered a Programmable Logic Controller for the acquisition, treatment and process of the signals generated by the field instruments. The process will be monitored and supervised continuously, so and SCADA system will be developed for this task in an operation room, and for the field will be implemented a Human Machine Interface. It will be considered the different rules and standards that are in force in our country at the moment of the design.
