Dynamic Pre-Cooling (High-Suction Capacity Chambers): Precisely designed to control cooling rate and airflow velocity, ensuring uniform temperature absorption throughout both packaged and unpackaged products.

Dynamic Cooling: Provides multi-point digital monitoring and full 24-hour regulation of temperature and humidity across the entire cold room, extending storage life by 15–20% compared to standard conditions.

Reinforced Cold Room: A flexible system that allows existing refrigeration chambers and equipment to be used both for light pre-cooling and subsequent storage.

Pallet Placement: Maintain 5–10 cm spacing between pallets along the airflow direction to promote even cooling and temperature uniformity.

IMPORTANT TIPS
  • Use high-capacity Dynamic Pre-Cooling systems for rapid, uniform cooling.
  • Ensure fast pre-cooling and maintain the cold chain throughout all handling stages.
  • Dynamic Cooling is ideal for preserving sweetness and overall quality.
  • Manage CO₂ levels carefully: moderate concentrations help delay sucrose loss and maintain freshness.
  • Store corn with husks intact — provided that pre-cooling is thorough and relative humidity is maintained between 88–92%, extending total storage life.
  • Disinfect all tools, equipment, and storage areas before harvest and storage operations.
  • Use modified atmosphere bags to further prolong freshness and quality.
