Metal dryer is an automatic drying solution designed for egg tray production lines. It reduces moisture of freshly molded pulp trays from 60–70% to 10–15%. This gives egg trays optimal structural strength and protection against mold and deformation, ready for storage and shipment. Compared to natural air-drying or brick tunnel kilns, the metal dryer delivers more uniform drying, higher thermal efficiency, and weather-independent continuous production. It is the preferred choice for medium and large-scale egg tray manufacturers.

How Does a Metal Dryer Work? – Full-automatic Drying Process
Step 1: Wet Pulp Tray Loading
Freshly demolded egg trays (~60–70% moisture) are loaded onto a conveyor belt and fed into the drying chamber at a steady speed.
Step 2: Hot Air Circulation & Heating
Circulating fans distribute hot air uniformly throughout the chamber, rapidly evaporating moisture within the egg trays. Zone temperatures range from 80–90°C (lower), 150°C (middle), to 200–210°C (upper).
Step 3: Moisture Removal
With an automatic dehumidification system, water vapor is vented out of the chamber through dedicated exhaust ports.
Step 4: Finished Pulp Tray Discharge
When egg tray moisture falls under 15% and trays meet standard strength specs, they exit the line ready for packaging and storage.
Inside Look: Unique Designs of Multi-layer Metal Dryer
1-6 Layers Vertical Layout
Space-Saving & Large Capacity
Utilizing a multi-layer vertical structure (1–6 layers optional) to stretch the drying path upward rather than outward through an S-shaped continuous conveyor loop. This design expands your production capacity while reducing the required land area by over 50%.
Hot Air Circulation System
High-Efficiency & Energy-saving
High-velocity fans actively drive heated air to circulate uniformly across all layers, delivering 40% higher airflow than industry standards for uniform drying. This advanced aerodynamic design cuts fuel consumption, delivering over 10% energy savings compared to conventional metal dryers.
PLC Automation Control
Stable Egg Tray Quality
Features an intelligent PLC system for precise one-touch operation. By monitoring and automatically adjusting multi-zone temperatures in real time, it completely eliminates manual operational errors and fluctuating environmental factors, ensuring a consistent, high-yield production of premium egg trays.
Comparison of Drying Methods: Why Choose Automatic Metal Dryer
Natural Sun Drying vs Metal Drying System
Natural Sun Drying
- Long drying time (6–8 hours), highly dependent on light intensity.
- Production stops during rain or cloudy days; high risk of seasonal downtime.
- Requires massive drying space; high land acquisition/rental costs.
- Inconsistent drying levels between batches; high product breakage and defect rates.
- Requires heavy manual labor for turning, moving, and guarding; high labor costs.
Metal Drying System
- 20-25 mins completion; 24/7 operation regardless of weather conditions.
- Fully enclosed chamber; stable output in rain, snow, or winter.
- Compact footprint; no extra drying yard needed, maximizing factory space.
- Uniform temperature (error ±2°C); consistent batch quality with ≥98% yield rate
- Fully automated conveyor; 1 operator manages the line, reducing labor costs by 80%.
Brick Tunnel Kiln vs Metal Drying System
Brick Tunnel Kiln
- Long construction period (2–4 months).
- requires 3–5 hours of preheating; significant energy waste.
- Manual adjustment based on experience; risk of over/under drying.
- Brick cracks/dampness lead to complex repairs; major maintenance causes days of downtime.
- Immovable during factory relocation; total loss of civil engineering investment.
Metal Drying System
- Factory pre-fabricated; 7-day onsite assembly.
- Reaches working temperature in 20 mins; energy savings.
- PLC control; precise temperature control; fully automated adjustments.
- Modular metal structure; parts replaced within 2 hours; minimal production loss.
- Entire system can be dismantled and moved; protects your equipment investment.
ISO & CE Standard Certificate
Onsite-view of Beston Metal Egg Tray Drying System
- Dear friends, this is a complete structure of a BTF 5-8 metal drying egg tray machine. It is about to be shipped.
- Follow me. Let’s take a look of the inner layout of the metal dryer.
- Let’s go inside.
- Although it’s still empty, we can see the upper and lower sieve plate is already positioned. Later the trays will be running in between.
- The metal dryer we have is with 6 layers. You can see the rails from here.
- All the surface is made out of stainless steel. The wall is using a double layer design, in between is heat resistant wool.
