Project Brief

GMP RXH Hot-Air Circulating Trolley Ovens: Electric or Steam Heated

Specify heavy-duty SUS304/316L RXH walk-in hot-air circulating drying ovens (1 to 4 mobile trucks, 48–192 trays, 45–140 °C) for food, spice, and nutraceutical.

The Industrial Workhorse for Batch Food, Herb & Granule Drying

Across spice mills, dehydrated vegetable plants, and GMP nutraceutical facilities, the RXH series walk-in hot-air circulating oven is the benchmark batch platform in tray and cabinet dehydrators and commercial food dehydrators. Operators roll mobile stainless steel trucks—each holding 48 standard 640 × 460 × 45 mm trays—straight across a flush floor ramp into the insulated chamber.

Low-noise high-temperature axial flow fans push purified heated air through adjustable side louver plates, achieving >95% thermal circulation efficiency on either plant steam (0.2–0.6 MPa) or electric finned heaters.

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.

RXH Series Hot-Air Circulating Oven Model Specifications

Standard 1-truck through 4-truck industrial configurations:

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.

Commercial Dehydration Engineering Notes

  • cGMP Flush-Floor & Rounded Corners: Full TIG-welded internal seams eliminate dead corners where spice dust or sugar syrup could harbor microbes.
  • Automated Timed Moisture Damper: Program pneumatic/motorized exhaust dampers to vent humid vapor periodically without manual operator intervention.
  • Inlet Air Filtration: G4/F8 or H13 HEPA fresh-air intake filters protect ready-to-eat snacks and botanical powders from airborne plant dust.
