Gentle leafy vegetable washing solution for lettuce, spinach, cabbage and herbs, with bubble washing, spray rinsing, dewatering and air drying.
Suitable Materials
Leafy vegetables need a washing process that is strong enough to remove sand, but gentle enough to protect the leaves. Joyshine designs leafy vegetable washing lines around material condition, cutting state, target capacity and downstream packing requirements.
The typical solution combines feeding, sorting, bubble washing, spray rinsing, vibration dewatering and optional air knife drying. Each section can be adjusted to match lettuce, spinach, cabbage, kale, parsley and other fresh herbs.
Washing Challenges
- Hidden sand - Mud and sand can remain inside leaf folds, stems and cut edges.
- Bruising risk - Tender leaves are easily damaged by strong mechanical impact.
- Water control - Fresh-cut leafy vegetables need surface water removal before packing.
Recommended Washing Method
Gentle bubble washing
Bubble agitation separates leaves and loosens soil without harsh impact.
Spray rinsing
Clean-water spray removes floating residue after the main washing tank.
Vibration dewatering and air drying
Surface water is reduced before weighing, cutting or packing.
