Aims of Bulk diagnosisAims of Bulk diagnosisObjectif du diagnostic des foursObjectif du diagnostic des fours

To identify the principle origins of energy loss during curing / Identifier les principales causes de déperdition d’énergie au cours du séchage

To finalize an excel tool to raise growers awareness on energy consumption / Mettre au point un outil excel pour sensibiliser les producteurs aux problèmes d’énergie
