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 to 6 layers available), it extends the drying route upward via an S-shaped continuous conveyor loop. This design boosts production capacity and cuts floor space requirements by more than 50%.
Hot Air Circulation System
High-Efficiency & Energy-saving
The unique circulating fan makes the internal circulating air volume of the metal dryer 40% higher than that of the peers. The automatic dehumidification system saves energy by more than 10% compared with the peers.
PLC Automation Control
Stable Egg Tray Quality
Intelligent PLC system allows real-time monitoring and adjustments. It avoids manual operation errors and the impact of changing environmental conditions, ensuring consistent production of premium egg trays.
Comparison of Drying Methods: Why Choose Automatic Metal Dryer
The automatic metal dryer is a highly recommended egg tray drying method due to its zero weather dependence, high thermal efficiency, small footprint, fast construction, and ≥98% egg tray qualification rate compared to natural drying and brick drying.
| Dimension | Natural Drying | Brick Drying | Metal Drying |
|---|---|---|---|
| Drying Time | 6–8 hours | 15-30 minutes | 20 minutes |
| Weather Dependence | Fully dependent on sunlight | Very low | None |
| Temperature Uniformity | Poor | Medium (Some lag in temperature control) | Excellent (Precise control) |
| Product Consistency | Poor | Medium | High (≥98% qualification rate) |
| Footprint | Very large | Large (40–70m in length) | Small (20-25m in length) |
| Labor Needs | High | Medium | Very low (PLC automatic control) |
| Energy Consumption | — | High (Low thermal efficiency) | Low |
| Construction Period | — | > 45 days | 30 days |
| Mobility | — | Cannot move | Movable |
| Maintenance Convenience | — | Inconvenient | Convenient |

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.
