3. Ice pre-cooling
Ice pre-cooling is to absorb the heat of fruits and vegetables through the melting of ice to cool the fruits and vegetables. It includes putting ice in the packing box or tray, or covering the tray with ice. This cooling method is actually often used in transportation. The ice cooling method is suitable for products that are not easily damaged by contact with ice or products that require immediate pre-cooling in the field. However, lowering the temperature and maintaining product quality has limited effects and can only be used as an auxiliary measure for other pre-cooling methods. Suitable for Brussels sprouts, broccoli, sweet corn, carrots, celery, spinach, spring onions, etc.
COLDMAX believes that ice pre-cooling is not actually a real pre-cooling method, but an auxiliary cooling method during transportation. Ice pre-cooling is only suitable for very few types of fruits and vegetables.
