Project Brief

Industrial Mesh-Belt Tunnel, Vacuum & Fluidized-Bed Food Dryers

Scale continuous food dehydration from 200 to 1,500+ kg/h on multi-layer SUS304 mesh-belt tunnel dryers, or preserve bioactives in 35 °C vacuum cabinets.

Continuous Tonnage & Ultra-Low-Temperature Specialty Platforms

When raw vegetable, fruit, or pet-treat throughput exceeds 2–3 metric tons per day, loading hundreds of individual trays by hand becomes your biggest labor expense. Within commercial food dehydrators, continuous multi-layer mesh-belt tunnels automate feeding, turn product gently between 3 to 5 stacked belts, and discharge cooled dried pieces directly to multihead weighing lines.

Explore continuous tunnels in multi-layer mesh belt dryers and oxygen-free drying in vacuum and fluid-bed food dryers.

Six-stage commercial food dehydration and barrier pouch packaging workflow
Uniform slice thickness and post-dryer cooling prevent moisture rebound inside sealed retail pouches.

Continuous & Specialty Dryer Comparison

Select between belt, fluidized-bed, and vacuum chambers by particle geometry and oxidation sensitivity:

Dryer Technology Material Geometry Typical Capacity Key Process Advantage
DW 3–5 Layer Mesh Belt Slices, strips, cubes, chews (5–50 mm) 200–1,500+ kg/h Independent temp/air speed in each belt zone
ZLG / GF Fluidized Bed Free-flowing granules, peas, seeds (0.1–6 mm) 150–1,000 kg/h Rapid 15–40 min residence; uniform fluidization
FZG / SZG Vacuum Dryer Pastes, berries, herbs, extracts 50–300 kg/batch Boils moisture at 35–50 °C; zero oxidation

Wet batch and hourly capacity comparison across kitchen cabinets, RXH truck ovens, vacuum dryers, and mesh-belt tunnels
Transition from batch trolley cabinets to multi-layer mesh-belt tunnels once continuous wet feed exceeds 200–300 kg/hour.

Commercial Dehydration Engineering Notes

  • Gentle Inter-Belt Cascading: As slices drop 150 mm from Belt 1 onto Belt 2, pieces flip automatically—exposing fresh wet surfaces and breaking clumps.
  • Independent Zone Temperature Profiling: Run higher evaporative heat on top wet belts (70–85 °C) while finishing gently on bottom belts (50–55 °C) plus an ambient cooling section.
  • Full Hinged Side Access Doors: Full-length insulated side doors expose belt undersides and fines-catch pans for fast end-of-shift CIP/washdown.

Four-stage recirculation and moisture-exhaust damper control inside commercial hot-air tray dryers
Staged exhaust control vents heavy early moisture while recirculating 80–85% of heated air during falling-rate drying.
