Potatoes. Storage parameters

Recommended Storage Volume

Potatoes should be stored in single-bulk volumes of up to 3,000 tons for optimal airflow and temperature stability.
Fresh-air supply requirement: 120 m³ per ton of produce.

Optimal Temperature (t°C)

Storage temperature depends on the potato variety and its intended use:

• Table potatoes: +3°C

• French fry/processing potatoes: +8°C
  General storage range: +3°C to +8°C

Humidity

Maintain relative humidity at 95% to prevent dehydration and preserve tuber firmness.

CO₂ Levels

Excess carbon dioxide must be continually removed.
Maximum CO₂ concentration: ≤ 5%.

Storage Life

• Year-round storage with refrigeration equipment.

• Until April when using an aeration (active ventilation) system.

Storage Facility Parameters

Once placed into storage, potatoes must go through four key post-harvest processes:

1. Drying

2. Curing

3. Cooling

4. Long-term storage

Each phase requires a specific airflow and temperature mode.

Potatoes can be stored in bulk or container systems:

• Bulk storage without humidification: maximum pile height 4.5 m

• Bulk storage with humidification: maximum pile height 6 m
