Description

Technical Field

[0002] The storage and transportation of vegetables after picking need to be scientifically managed to maintain freshness. Most vegetables require low temperatures (0-4°C) to inhibit the activity of respiratory enzymes, slow metabolism, and extend the shelf life by 3-5 times. Leafy vegetables have thin cell walls, and water evaporates quickly at room temperature, with more than 20% lost within 4 hours. Therefore, leafy vegetables should be precooled to the target temperature within 30 minutes after picking, otherwise the quality will drop rapidly even if refrigerated later. The commonly used method is water cooling, which can quickly cool down while maintaining humidity.

The atomizing nozzle sprays the vegetables, and the atomizing nozzle facilitates uniform water spraying, thereby improving the fresh-keeping quality of the vegetables. However, for freshly picked leafy vegetables, especially in summer, it is necessary to first spray the vegetables with water to cool them down, otherwise the quality of the vegetables will be seriously reduced, and then moisturizing and preserving treatments are performed.
