Low-Pressure Pre-Cooling Chambers (Wet-Bulb Type): Specialized units suitable for unpackaged aromatic herbs immediately after harvest. These systems regulate humidity and create a low-pressure environment that rapidly reduces temperature without damaging delicate tissues. |
Dynamic Pre-Cooling (High-Suction Capacity Chambers): Tailored for both packaged and unpackaged herbs. Ensures even temperature distribution by controlling air speed and absorption rate across the entire product mass. |
Dynamic Cooling: Multi-point monitoring of temperature and humidity allows precise adjustment throughout the cold room 24/7. Extends storage life by 15–20% beyond standard conditions. |
Natural Airflow Cold Room with Mist Atmosphere: A highly specialized chamber combining natural air circulation with fine-mist humidifiers — ideal for products sensitive to air velocity and requiring very high humidity. |
- Manage CO₂ levels: Elevated concentrations help slow deterioration and maintain leaf color.
- Use high-capacity pre-cooling systems for fast and uniform temperature drop immediately after harvest.
- Maintain the cold chain during all handling, storage, and transport phases.
- Install ozone generators to reduce microbial and fungal contamination.
- Use modified-atmosphere packaging (MAP) to extend shelf life and preserve aroma and texture.
- Remove ethylene with specialized absorbers to prevent premature yellowing and loss of quality.
