AUTOMATION ENGINEERING SERVICE FOR CORN STEEPING AND WET MILLING PROCESSES, IN FACTORY OF GLUCOSE AND CORN DERIVATIVES (GYDEMA):

CIENFUEGOS, CUBA

Abstract

The factory of glucose and corn derivatives of Cienfuegos is one of the most important factories of this city’s industrial pole. As part of the modernization of processes on this factory, an automation engineering service was carried out by the CEDAI Enterprise of Cienfuegos. The main goal of this service was to implement a control system that will optimize steeping and wet milling processes, improve the process operation, increase the productive capacity of these areas as well as the product quality. To do so, many tasks were executed, it was necessary to replace the obsolete equipment, as well as pneumatic equipment, and the incorporation of new technologies for process control. Likewise, the development and implementation of a SCADA for steeping process. On the other hand, the wet milling process was provided with a modern MCC, equipped with advanced technology to this end, which includes a PROFINET network for motor control and using SIEMENS technology. Additionally, an HMI based SCADA was implemented to control the wet milling process. With the final application of this service, centralized control of pumps and motors of these processes was achieved, as well as supervise the status of the corresponding equipment and continuously monitoring the process variables through simple interfaces, easy to use and interact. Thus far, the developed control systems has been operating for more than two years and its implementation was a step forward for the technological upgrade of the factory, improving consumption rates, saving energy and increasing the production rates, as well as the quality of the product.
