New construction systems for cold stores for fruit and vegetables preservation under normal and modified atmosphere.

Author(s) : BONSEMBIANTE E., BOSCHELLO R.

Summary

As everybody knows, the basic principles in the field of preservation in controlled atmosphere are merely physiologic. In addition to the temperature fall, it is possible to use atmospheres which are poor of O2 and more or less enriched by CO2 .
The oxygen reduction within a certain value causes a lowering of the product's respiratory rythm, and this could be reduced by rising the CO2 which should not go beyond a certain concentration to avoid product damages.
In recent years some cold rooms are coming more and more into diffusion for the purpose to make atmospheres with a low percentage-of O2 and CO2 called ULO (Ultra Low Oxygen). For this purpose it is necessary to build cold rooms perfectly, gas-proof; infact it is absolutely necessary for the cold rooms to be hermetic in order to avoid oxygen infiltrations from outside which would make impossible to reach the predetermined working conditions.
