How to Prolong the Life of Agricultural Products

A cooling technique is being designed which allows for longer storage of agricultural products obtaining an optimum temperature of 0 degrees throughout the cooling area.

Tuesday, August 26, 2014

From a statement issued by the Foreign Trade Promotion Office of Costa Rica (Procomer):

Permachill is a new cooling technique developed by the Dutch company TOP bv. The technique in question cools in a stable manner and achieves an optimum temperature of just above 0 degrees throughout the cooling zone. This ensures that the produce can be stored longer and suffer fewer losses compared to traditional cooling technologies. According to the company this is an interesting solution for all participants in the distribution chain, both for reasons of economy and sustainability.

According to the company conventional techniques cool products at temperatures of between 4 and 7 ° C using air cooling. The airflow causes fluctuations in temperature which can cause freezing which damages delicate products. The stable cooling technique used by Permachill is not based on a central cooling unit, but uses the walls of the cooling zone as a cooling element. This makes it possible to cool the product evenly and keep it cold. The optimum temperature, which is just above 0 ° C in the case of many products, can be achieved with this system without risk of freezing. The product goes into "hibernation", and therefore its lifespan is extended.
