Desarrollos Alimentarios, under its trade name Frumen, is a manufacturer of breadcrumbs at national level and has decided to collaborate with Gas Natural Fenosa, as an Energy Services Company (ESCO), to improve the energy efficiency of its production factory in Azuqueca de Henares (Guadalajara). The project aims to refurbish and optimise the facilities, based on the implementation of the best techniques available in the factory’s different energy consumption areas. The company has also committed to a project to recover different residual heat sources for assessment and injection back into the productive process. Desarrollos Alimentarios, S.A. has a factory in Azuqueca de Henares (Guadalajara) that has been dedicated to the production of breadcrumbs since 1978. This product is sold under the brand name Frumen and from the outset has been known for its innovation in its automated productive industrial process.

This process comprises various stages, all of which require an energy supply. Particularly significant as regards thermal production, is the generation of heat for the dough mixing process (supply of hot water), proving (generation of optimal humidity and temperature conditions), baking (cyclothermic natural gas-powered oven, with an input of steam from an external boiler) and the grinding/drying process (hot air to generate the finished product with very low moisture content). All this involves an intensive energy consumption process, in particular natural gas, that represents around 70% of its energy costs structure.

Gas Natural Fenosa drew up a plan for Desarrollos Alimentarios to achieve a lower energy consumption for the factory (MWh/kg of product produced) thereby increasing its competitiveness thanks to a better use of resources and reducing the factory’s pollutant emissions. Read more…
