The mango washing waxing and grading line is an automated processing equipment that integrates washing, drying, waxing, and grading. It is widely used in mango export bases, fruit and vegetable processing plants, and agricultural product cold chain centers. It can significantly improve the appearance quality of mangoes and extend their shelf life.
Mango Washing Line Overall Flow:
1. Feeding and Pre-selection: Manual or automatic feeding to initially remove damaged and rotten mangoes.
2. Cleaning System: A combination of bubble cleaning and spray cleaning effectively removes mud, sand, and surface impurities.
3. Scrubbing and Draining: Soft-bristled brushes perform rolling cleaning to avoid damaging the peel; vibration or roller draining reduces residual moisture.
4. Hot Air Drying: A low-temperature circulating hot air system ensures rapid drying and prevents water stains.
5. Uniform Spraying of Food-Grade Fruit Wax: Enhances fruit surface gloss, effectively reduces moisture evaporation, and extends shelf life.
6. Sorting and Grading: Grading by weight, size, or appearance; expandable with a visual sorting system (color, defect detection) to meet different market and packaging specifications.
7. Conveying and Packaging: Connects to manual or automatic packaging systems; compatible with cardboard boxes, plastic crates, or export pallets.
1. Centralized PLC control throughout the entire mango grading line ensures stable operation and continuous operation, significantly reducing labor costs and increasing production capacity.
2. Designed specifically for mangoes, featuring soft brushes and a buffered conveyor structure to minimize loss.
3. Waxing produces a uniformly glossy surface on the mangoes, effectively slowing moisture loss and enhancing their export grade and market competitiveness.
4. Production capacity typically ranges from 1 to 20 tons/hour, and can be flexibly configured according to customer plant layout, national voltage standards, and target markets.
5. Versatile for multiple fruit types, suitable not only for mangoes but also for citrus fruits, avocados, apples, oranges, lemons, and more.
