The date palm is one of humanity's oldest cultivated crops, grown in tropical and subtropical regions; date cultivation in Iran dates back about 3,000 years. Iran produces roughly 1.4 million tonnes per year across six provinces (Kerman, Hormozgan, Sistan and Baluchestan, Bushehr, Khuzestan, and Fars) and ranks second worldwide after Egypt, exporting dates to 65 countries. That production and export volume requires year-round holding, which calls for date cold rooms. Storing dates in cold storage prevents spoilage and keeps fruit wholesome for extended periods.
Date holding uses above-zero cold rooms in capacities of 13, 20, 25, and 30 tonnes, with compressor power from 2 to 10 hp.
Suitable temperatures for date storage:
● One-year storage: −18°C
● Six-month storage: −3°C
● Less than three months: 0°C to below 5°C
Date cold room compressor
The compressor is the most critical component of a date cold room. Selecting the right unit requires advice from qualified specialists. Many compressor types are built for different cold room requirements. Well-known brands include Bitzer, RefComp, and Copeland. They are classified by operating principle into dynamic and positive-displacement types, each with several subcategories.
Date cold room condenser and evaporator
Condenser and evaporator selection is equally specialized and demands solid engineering experience. Condenser, evaporator, compressor, and other cold room equipment must be matched as a complete system.
Date cold room insulation
Insulation quality improves cold room efficiency. The insulation type used in construction directly affects cold room value and price. Sandwich panels are the most common insulation in cold rooms.
Date cold room electrical panel
An electrical control panel regulates cooling in the date cold room. More advanced panels provide better overall cold room management.
Date cold room door
The cold room door must be chosen carefully. It should suit hall dimensions and loading equipment such as forklifts and reach trucks.
Date cold room price
Building a date cold room requires application-specific equipment, so there is no single fixed price. Compressor type, condenser, body insulation, door, room dimensions, power supply, and other factors all affect cost. A universal list price for cold room construction is therefore not feasible.
