Heat exchanger shelves for better temperature control of food in open-type display cases.

Author(s) : CLODIC D., PAN X.

Summary

Open-type display cases show very high temperature differences, and even the European standard EN 441 accepts large temperature intervals associated with the defrosting process and what is known of the actual technology level. A new global design of open-type display case has been realized in order to limit drastically the temperature differences of the products depending on their position on the shelves. A defrosting system that does not heat up the cooling air has been developed. The shelf itself is transformed into a heat exchanger, the airflow circulates inside the shelf and is sprayed over the food displayed on the shelf underneath. Tests show that food can be maintained at a constant temperature plus or minus 1.5 K.
