CONSTRUCTION OF THE CONTROLLED ATMOSPHERE REFRIGERATOR
Chernivtsi region, Sokyriany district, Kobolchyn village
Refrigerator with controlled refrigeration regime and atmosphere is used for storage of fruit. This fruit storage consists of 17 separate storage chambers with a total capacity of 2.2 thousand tons. Unbundling of chambers makes it possible to regulate the temperature regime and atmosphere environment of each. Operating temperature of the chamber is 1-2°С. Air conditioning daily cools filled chambers for 1,0-1,5 ° C to reach operating temperature and prevent fruit freezing. After that, chambers are scavenged with nitrogen up to the level 7-9% oxygen, further reduction of oxygen occurs due to the respiratory process of apples. The composition of controlled atmosphere in the refrigerators’ chambers is oxygen - 1.5%, carbon dioxide - 1.5%, nitrogen - 97%.
