Resumen

SARIEGO TOLEDO, Yanet; PEREZ YBANEZ, Sandra; GARCIA NOA, Eduardo  y  RODRIGUEZ, Lázaro. Energy evaluation of an ice cream plant. Energética [online]. 2017, vol.38, n.1, pp.42-53. ISSN 1815-5901.

The ice cream production process is a high consumer of energy mainly in the cooling steps. In those ice cream production plants that have many years of exploitation, in general there are low energy efficiency and the consumption indicators are high. These are indicating the necessity to find the best operating conditions to reduce the costs to better levels. Focus in that, the present work has as main objective to evaluate the energy efficiency of the refrigeration system of an ice cream production plant in the Dairy Complex Havana. As fundamental results were obtained that the refrigeration system of the analyzed plant is working with an operating rate of 1,75, an with a relative yield of 58,35 %. Also the removed heat by the system at every stage was determined and it was found that the rate of energy consumption is of 0,047 kW - h / kg of product. The alternative proposal for the increment of the energy and exergy efficiency is achievable from the thermodynamic point of view.

Palabras clave : energetic efficiency; ice cream; refrigeration system; removal of heat; thermodynamic.
