Refrigeration chambers with Controlled atmosphere
01.09.2022Share
Annually, a huge amount of food is grown at agricultural and farming enterprises: fruit and vegetables, meat and dairy products, grain products, sunflower oil, etc. Ukraine is one of the leaders in the world export of grain, nuts, rapeseed, sunflower oil and meat. Berries and fruits require proper storage conditions, this is the main factor for preserving their marketable appearance. For proper storage of fruits, it is necessary to create certain conditions, this is exactly what refrigerating chambers with an adjustable gas environment are like. For example, you can give a table with the shelf life of fruits when using a camera with and without Controlled atmosphere.
| Fruit type | Standard chamber | Regulated gas environment |
| Apple | 5 months | 8 months |
| Pear | 2 months | 5 months |
| Grapes | 3 months | 6 months |
| Peach | 5 weeks | 10 weeks |
| Cherry | 10 days | 32 days |
| Currant | 7 days | 42 days |
| Strawberry | 5 days | 30 days |
The Ralco Technic company successfully implements projects in Ukraine and Europe for the design and construction of Controlled atmosphere refrigerating chambers. 
Regulated gas environment: principle of action
Refrigerating chambers for different types of fruit will differ in terms of technical parameters due to different requirements for storage conditions. An experienced engineer knows what to pay attention to when designing an object, therefore, even at the stage of initial information collection, he discovers the following information:
- volume of loaded products;
- type of fruit;
- degree of product maturity;
- technological processes.
< li>external and internal temperature conditions;
The main thing is to know that vegetables and fruits breathe. They absorb oxygen and release carbon dioxide. During the release of oxygen, moisture evaporates, which affects the decrease in product weight. With the help of special equipment, this process can be regulated, maintaining the temperature required for the fruit. For example, the storage of apples in the Controlled atmosphere provides conditions, during which gas exchange will be carried out with increased CO2 content at a certain temperature. To reduce the content of oxygen, its partial pressure and increase the concentration of CO2, it is necessary for the environment to be closed. Only in this case, the gas exchange will slow down and the storage period will increase. The Controlled atmosphere refrigerating chamber is designed taking into account:
- compliance of the material with gas permeability;
- resistance to absorption and emission of odors;
- resistance to moisture;
- strength;
- fire resistance;
- compliance with the necessary storage parameters.
Thermal insulation of the Controlled atmosphere refrigerating chamber involves the use of special polyurethane foam panels of a certain thickness, as well as doors and thermal curtains. The principle of their construction resembles a designer, which significantly speeds up the installation process, and also gives more options for choosing configurations of cameras with Controlled atmosphere. Such panels are mounted on a metal frame in a short time. Using the experience of specialists, it is possible to design and build a vegetable storage for 5 thousand tons even before the start of harvesting.
