1. Some key figures
The below figures will help you better understand why the Lagarde Steam & Air process uses much less energy than any water spray process.
Any system using water as an intermediate fluid for heating requires much more energy than direct steam heating… and will consequently need to use even more water to cool down the process water and the products.
2. Thermal exchange capacity of different fluids
Every scientific study shows Steam is the best heat medium for a perfect transfer of energy !
3. Concrete case study with meat pâté cans
Heat exchanger efficiency: 95 %
Cooling water : 120 L per basket – 1 Kcal / °C / Kg
Product : 300 Kg per basket – 0.75 Kcal / °C / Kg
Energy request for heating:
Lagarde STEAM & AIR : 300 Kg x 0.75 = 225 Kcal / °C
HOT WATER SPRAY : (300 Kg x 0.75 + 120 Kg x 1) / 0.95 = 365 Kcal / °C
