Model: ANC-BXK Series
Cold Storage Engineering
Fruit and vegetable fresh-keeping cold rooms operating at 0–5°C and 90–95% relative humidity, with humidification and low-temperature-difference air coolers for short- to medium-term storage.
Key Features
- Gentle 0–5°C temperature with 90–95% high humidity, suppressing respiration and moisture loss
- Ultrasonic/high-pressure spray humidification with automatic humidity control linked to room temperature
- Low-temperature-difference, high-air-volume fresh-keeping air coolers reduce surface moisture loss of fruit and vegetables
- 100mm polyurethane room body, Class B1 fire rating, easy-to-clean interior walls
- Expandable with simple controlled atmosphere (oxygen reduction) or ethylene removal to extend storage life
Applications
- Fruit-growing cooperatives and post-harvest processing centers
- Fruit and vegetable wholesale markets and distribution
- Supermarket fresh-food distribution centers
- Pre-cooling and temporary storage for fruit and vegetable exports
- Flower and nursery plant preservation
Fruit fresh-keeping rooms use gentle 0–5°C temperatures with 90–95% relative humidity to suppress respiration and moisture evaporation, preserving surface gloss, crispness and shelf life; a basic facility in post-harvest handling and distribution.
Temperature/humidity control: adjustable 0–5°C room temperature at 90–95% RH; low-temperature-difference, high-air-volume fresh-keeping coolers reduce surface moisture loss, with ultrasonic or high-pressure spray humidification automatically linked to room temperature.
Room body: double-sided color steel polyurethane sandwich panels, 100mm thick, core density ≥40kg/m³, Class B1 fire rating; moisture-proof insulated floor and easy-to-clean interior walls support frequent handling and wash-down operations.
Refrigeration system: reciprocating or scroll parallel units with air- or water-cooled condensing, selected by room volume and intake; air cooler layout ensures even airflow and avoids local freezing from direct airflow onto stacks.
Control and preservation aids: microcomputer or PLC automatically regulates and records temperature and humidity; optional simple CA (oxygen reduction) or ethylene removal further extends storage life.
Delivery: 5–10 days design, 20–30 days production, 5–10 days installation, delivered turnkey with temperature and humidity compliance tests.
