In the egg tray production process, the formed wet products contain over 70% moisture and must be properly dried to meet the requirements for stacking, packaging, and use. As a key component of the pulp molding production line, the egg tray drying system has a direct impact on drying efficiency and product quality stability.
Currently, the common drying methods for egg trays include natural drying, brick kiln drying, and metal drying. Based on the customer’s investment budget, production capacity needs, and local climate conditions, we can offer suitable drying solutions. Choosing the right drying method not only improves production efficiency but also helps control overall production costs.
Natural Drying
- Features: Low investment, zero energy consumption, easy operation.
- Suitable for: Regions with dry climates, long hours of sunlight, and ample open space.
- Recommended models: Single-side egg tray machines or small-scale lines with a capacity of 1000–1500 pcs/h.
- Best for: New investors, small-scale production, or limited budgets.
Natural drying involves manually placing wet trays on clean surfaces or drying racks to air dry using sunlight and natural wind. Drying typically takes 4–6 hours. This method is simple and cost-effective but heavily weather-dependent, making it less ideal for continuous production.
Brick Kiln Drying
- Features: Simple structure, durable, can operate in all weather.
- Suitable for: Areas with less stable climates but low labor and fuel costs.
- Recommended models: Medium-scale egg tray production lines with 2000–4000 pcs/h capacity.
- Best for: Small to medium factories with basic infrastructure.
Brick kiln drying uses a tunnel built with bricks and heated by wood, coal, or gas. Wet trays are moved inside on tracks or conveyors, where they are dried by hot air circulation. This is a cost-effective method for users looking for a reliable solution with manageable construction and operation costs.
Metal Drying Line
- Features: High automation, precise temperature control, and fast drying speed.
- Suitable for: Large-scale, standardized production with continuous operation.
- Recommended models: Four-side or eight-side egg tray machines with capacities of 4000–8000 pcs/h.
- Best for: Large factories or export-oriented businesses with steady demand.
The metal drying line consists of insulated metal panels, multi-layer conveyors, and automatic temperature control systems. It supports multiple heating sources such as natural gas, diesel, or electricity.
The system can run 24/7 and works in sync with the forming machine, saving labor and improving overall productivity. We offer customized designs based on your plant layout and output needs.
How to Choose the Right Egg Tray Drying System?
Selecting the right egg tray drying system depends on several key factors:
- Production volume: Higher output calls for metal drying lines with higher efficiency.
- Climate and space: Sun-rich areas with open space are suitable for natural drying.
- Budget and operation costs: Natural or brick drying suits lower budgets; for long-term efficiency, metal drying is recommended.
- Factory setup: New plants can be designed for metal dryers, while existing brick kilns can be upgraded and reused.
