Egg tray production is an essential process in the pulp molding industry, ensuring that eggs are safely packaged for transport and storage. However, an often-overlooked but crucial step in manufacturing is the drying process. Proper drying is essential for durable and high-quality egg trays. So, how many drying methods are available for egg trays? In this guide, we’ll explore the three main drying systems and help you choose the best one for your business.
How to Perfectly Dry Egg Trays | 3 Ways
YG Machinery offers three main drying systems to suit different production needs.
1️⃣ Natural Drying (Sun Drying)
Best for: Small-scale production (1,000–1,500 trays per hour)
Natural drying is the simplest and most cost-effective method, commonly used in areas with high temperatures and low humidity. This method requires minimal investment but relies heavily on weather conditions.
How It Works:
- Freshly molded wet egg trays are placed in an open space under direct sunlight.
- The trays dry over 4–6 hours, depending on temperature and humidity.
- Once completely dry, the trays are stacked and packaged.
Pros:
✔ Low investment – No fuel or electricity costs.
✔ Eco-friendly – Uses natural heat for drying.
✔ Easy to set up – Requires only a flat, well-ventilated area.
Cons:
✖ Weather-dependent – Inefficient during rainy or humid conditions.
✖ Slow drying process – Can take several hours to days depending on the climate.
✖ Requires large space – Needs a big open area for proper sun exposure.
2️⃣ Brick/Kiln Drying System
Best for: Medium to large-scale production (2,000–5,000 trays per hour)
A brick drying system is a semi-automated drying solution that significantly reduces drying time compared to natural drying. It is ideal for businesses with growing production needs.
How It Works:
- A brick-built drying chamber is constructed with a heat source, such as coal, wood, or natural gas.
- Wet trays are placed on racks inside the chamber.
- Hot air circulates within the system, drying the trays in 20–30 minutes.
Pros:
✔ Faster drying – Reduces drying time from hours to minutes.
✔ More reliable – Works in all weather conditions.
✔ Lower operational costs – Compared to fully automated systems, it requires less energy.
Cons:
✖ Requires initial investment – Costs of constructing the brick chamber.
✖ Longer installation time – Takes time to build and set up the system.
✖ Uses fuel – Requires wood, coal, or gas for heating.
3️⃣ Metal Conveyor Belt Drying System (Automatic Drying)
Best for: Large-scale production (5,000–7,000+ trays per hour)
For high-efficiency production, automatic metal drying systems are the most advanced option. They are commonly used by large egg tray manufacturers aiming for fast, continuous, and efficient drying.
How It Works:
- Wet trays are placed on a multi-layer conveyor belt.
- The trays pass through a controlled heating system powered by gas, diesel, or electricity.
- The process ensures even drying in just 15–20 minutes.
Pros:
✔ Fastest drying method – Ideal for large-scale production.
✔ Fully automated – Minimal labor required.
✔ Consistent quality – Even drying prevents tray deformation.
✔ Space-saving – Uses a compact, conveyor-based structure.
Cons:
✖ Higher initial cost – Expensive compared to other methods.
✖ Energy consumption – Uses electricity, gas, or diesel.
✖ Requires skilled operation – Needs trained staff for maintenance and operation.
Comparison Table: Egg Tray Drying Methods
| Drying Method | Best for Production Capacity | Drying Time | Cost | Weather Dependent? |
|---|---|---|---|---|
| Natural Sun Drying | 1,000–1,500 trays/hour | 4–6 hours | Low | Yes |
| Brick Kiln Drying | 2,000–5,000 trays/hour | 20–30 minutes | Medium | No |
| Metal Conveyor Drying | 5,000–7,000+ trays/hour | 15–20 minutes | High | No |
Which Drying Method is Best for Your Business?
Choosing the right drying method depends on:
- Production Scale: Small-scale producers can start with sun drying, while larger businesses need brick kiln or automatic drying systems.
- Budget: If you’re looking for a low-cost method, natural drying or brick drying may be better. However, for high-volume production, an automatic conveyor drying system is ideal.
- Weather Conditions: If your area experiences unpredictable weather, consider an enclosed drying system.
- Energy Availability: If electricity or gas is expensive in your region, brick drying could be a cost-effective option.
Conclusion
Egg tray drying is an essential part of production that directly affects quality, efficiency, and cost. With three main drying methods—Natural, Brick Kiln, and Metal Conveyor—you can choose the best solution based on your production needs and budget.
