Automatic vegetable washing production line

The Industrial Lettuce Washing and Air-Drying Line is a high-efficiency, continuous commercial processing solution specially engineered for fresh leaf lettuce, iceberg lettuce, spinach, and other delicate leafy greens. Featuring an advanced Dual-Stage Air Bubble Washing + Multi-Stage Air-Knife Drying Process, this automated processing line thoroughly removes soil, debris, and impurities while protecting fragile leaves from bruising or structural damage.

Built with heavy-duty food-grade SUS304 stainless steel, the line incorporates high-pressure air-bubble surging, top spray rinsing, continuous water filtration recycling, and high-velocity ambient air drying. It provides clean, ready-to-pack leafy vegetables for commercial food processing plants, central kitchens, fresh-cut produce suppliers, and salad manufacturing facilities.
