Abstract

The goal eight of the 2030 Agenda aims to promote sustained, inclusive and sustainable economic growth, full and productive employment, as well as decent work for all. International trade is an indispensable means to stimulate and achieve its fulfillment. Maintaining productivity and profitability in the production of exportable goods, such as Cuban rum, is essential to meet this goal. The present article presents a methodology to determine the adequate technological equipment that allows reducing the losses of materials and products during the obtaining of rums, at the UEB (Base Business Unit) Manuel Fariñas Núñez, in Santiago de Cuba. To find out the existing technological problems, an observation of the operation of all the technical devices used in production was carried out. Data regarding significant operating variables were collected and the company’s warehouse was visited to quantify reserve supplies. From a macroscopic balance of mechanical energy, a mathematical model and an algorithm for solving the problem were developed. During the investigation, it was detected that in the filtration area of the aged rum there are losses of the product due to breakdowns in the pipes. The developed methodology allowed identifying the diameter that satisfies the operating conditions of the system; in addition, it allows obtaining calculation algorithms to select or identify optimal parameters in production systems. The correct selection and operation of technological equipment guarantees the productivity and profitability of a company.
