Cold rooms for fruits and vegetables
Technical specifications
Cold rooms for fruits and vegetables utilize robust insulation panels made of polyurethane or PIR polymer. These panels form the walls, roof, and floor, providing excellent thermal insulation and reducing energy consumption. For surface finishing, colored steel or stainless steel can be used. Panel thickness ranges from 75 mm to 150 mm, depending on the project. A professionally designed cold room door enhances airtightness and durability. The door can be hinged or sliding, effectively retaining cold air inside and minimizing heat exchange.
The system also incorporates a reliable condensing unit. Users can choose units with either air‑ or water‑cooling. Compressors from renowned brands deliver high efficiency and dependable performance. The condensing unit is matched to the room’s dimensions and cooling load. An internal air cooler ensures uniform distribution of cold air, thereby maintaining product quality.
Characters
In the cold rooms for fruits and vegetables, humidity must be carefully controlled. The relative humidity for most fruits and vegetables should be maintained between 85% and 95%. High humidity helps preserve freshness and reduces moisture loss. The system also maintains a precise temperature regime. Different products require different humidity levels: apples may need temperatures between 0°C and 4°C, while tomatoes may require temperatures between 8°C and 12°C. The system responds rapidly to temperature changes and protects all produce from overheating.
The composition of the air also plays a key role. For certain products, low oxygen levels and elevated carbon dioxide concentrations are required. These conditions slow down ripening and help preserve flavor. The system manages airflow to prevent pressure fluctuations. Balanced air circulation prevents bruising and maintains stability within the chamber.
