Automation Proposal for the Pasteurizer of the Hatuey Beer Factory of Santiago de Cuba

Abstract

The present work consists of an automation proposal for the pasteurizer of the bottling area of the Hatuey Beer Factory in the province of Santiago de Cuba, in order to improve the technical state of the same and to have a greater control of the pasteurization process developed by this, to obtain a higher quality in the finished product. A temperature control loop was designed for each zone of the machine, since by correctly controlling the temperature we guarantee the correct pasteurization of the product. For the realization of the same, one took into. account the variables present in the process because it is of vital importance the correct election of the instrumentation to use. The programming of the Mitsubishi PLC of the FX3U series is also performed, the PLC was programmed using the Contacts language (LD) and the interface for its connection with the graphic interface is RS-485. Its implementation will significantly increase the quality of the operation of the aforementioned system, as it will provide stability in the process in general and thus ensure a higher quality of beer or malt, as well as greater convenience to interact with the process to the workers of this plant.
