Cold storage with many internal floors with in PEB structures is designed by Metecno for G+5 (or) more floor constructions and also mezzanine floors (decking).Controlled atmosphere is applied to extend the storage life of fruits and vegetables. Most of them can be stored considerably for more time compared with normal 0o cold store. Infact CA reduces drastically metabolism and respiration of the fruits.Atmospheric air consists of 20.8% oxygen, 78% nitrogen and about 0.03% carbon dioxide. Controlled atmosphere is a technology based on variations of the parameters relative to atmospheric composition inside the cold-storage rooms, mainly lowering of the oxygen content and surveying the carbon dioxide value during the entire storage period of fresh produce.
The list of products that can benefit from being stored under controlled atmosphere is long. The main products are: Apples, Tomatoes, Mango, Avocado, Pineapple, Banana, Citrus fruits Pears, Kiwifruit, Plums, Blueberries, Strawberries, etc
The Sandwich insulated PUF panels that make the cells hermetically tight, retain the desired gas tight ratios. Metecno Panels have proven track record having successfully used in CA applications worldwide. Special resins are applied to panel joints to maintain the gas tightness and that it withstands a pressure of 30 mm water column for a period of 30 minutes consistently, as the Gas tight test is very important for the proper functioning of CA storages.
