The new control system is exclusive to GEA spiral freezers and is able to calibrate the freezer parameters through the continuous measurement of the level of freeze of the product at the freezer exit.
Mathieu Nouhin, GEA’s Product Manager Freezing, said: "There is no point in continuing to cool a product beyond 100 percent frozen but, until now, there has been no way of checking the level as a continuous part of the process.
"Callifreeze uses GEA’s unique sensing and control technology to measure the level of every product in the spiral. It then adjusts the machine to achieve perfect freezing in line with the customer’s requirements.”
He added that for several applications, 80% level of freeze at discharge is sufficient with the product being ‘finished off’ in the cold store for energy savings purpose. Results from one plant operating seven GEA freezers has showed a 10-15% production capacity increase with a reduction in energy consumption.
