Mango Dried Fruit Line – Osmotic Dehydration & Hot Air Drying for Soft Chewy Mango Slices
Our mango dried fruit line produces premium quality soft, chewy dried mango slices with natural color and flavor retention. The process combines osmotic dehydration (sugar infusion) with multi-zone hot air drying to achieve consistent moisture content and extended shelf life. An optional freeze drying module is available for crispy mango chips.
Complete Production Flow
1. Washing & Peeling
Fresh mangoes enter a bubble washer with chlorinated water (50-100ppm) for surface sanitization. An automatic peeling machine removes skin using rotating blades, followed by manual trimming to remove remaining spots.
2. Slicing
A high-speed slicer with adjustable thickness (3-10mm) cuts mangoes into uniform slices or strips. The machine handles up to 2 tons/hour with minimal crushing.
3. Osmotic Dehydration (Sugar Infusion)
This critical step replaces water with sugar to preserve texture and flavor. Mango slices are immersed in a sugar solution (35-50°Brix, typically sucrose + glucose) for 4-12 hours depending on:
Desired sweetness level
Slice thickness
Room temperature (or heated infusion tanks at 40-50°C for faster processing)
Osmotic dehydration removes 30-50% of initial water while adding sugar, which prevents browning and microbial growth.
4. Hot Air Drying
After draining excess syrup, slices are spread onto stainless steel trays or conveyor belts entering a multi-zone hot air dryer:
Zone 1 (60-65°C): Initial surface drying (2-3 hours)
Zone 2 (55-60°C): Bulk moisture removal (4-6 hours)
Zone 3 (50-55°C): Final conditioning to 15-18% moisture content
Total drying time: 8-12 hours depending on slice thickness and loading density.
5. Cooling & Conditioning
Dried mango slices are cooled to room temperature in a cooling tunnel, then transferred to conditioning bins for 12-24 hours to equalize moisture throughout each piece.
6. Packaging
Automatic packaging options:
Pre-made pouch machine (stand-up zipper bags)
Horizontal flow wrap (pillow packs)
Vacuum packaging (extended shelf life)
Nitrogen flushing (prevents oxidation)
Optional: Freeze Dried Mango Line
For premium crispy mango chips, we offer vacuum freeze drying:
Freezing: -40°C for 2-4 hours
Primary drying: Under vacuum (<100Pa), shelf temperature ramped from -20°C to 30°C (12-20 hours)
Secondary drying: 35-40°C for 2-4 hours
Final moisture: <3%
