The egg tray production process includes pulping, molding, drying, and finishing. The core equipment is the egg tray molding machine.
Taking the 1000 pcs/h egg tray machine as an example, it is ideal for small and medium investors due to its simple operation, stable output, and low investment cost.
1. Pulping
Waste paper, cartons, old books, and other raw materials are mixed with water in a pulping machine to form uniform pulp. The pulping system usually includes a pulper, a mixing tank, a pulp storage tank, and pumps to ensure stable pulp consistency for molding.
2. Molding
Inside the molding machine, the pulp is absorbed onto the mold surface to form wet egg trays. A 1000 pcs/h egg tray machine is commonly equipped with a single or double mold and can produce standard 30-cell egg trays as well as other pulp products. Molds can also be customized according to specific requirements.
3. Drying
Wet trays contain a high amount of moisture and require drying. Depending on the setup, the trays can be naturally sun-dried or dried using a metal drying line. For a 1000 pcs/h system, a compact single-layer or multi-layer metal dryer is often recommended to improve efficiency.
4. Final Shaping & Packing
After drying, the trays may be hot-pressed to make the surface smoother and denser. For easier transportation and storage, a baling machine can be added to compress the trays into organized bundles.
Why This Simple Production Line Works Well
- It uses কাঁচামাল হিসাবে বর্জ্য কাগজ, turning a low-value resource into a sellable product — cost of raw material is minimal.
- The required equipment (pulping + molding + drying) is compact enough for small or medium workshops, making startup easier.
- The process is flexible: by changing molds, you can offer different products (egg trays, fruit trays, cup holders, etc.), adapting to different markets.
- For small-scale production (≈ 1000 trays/hour), drying can be as simple as natural air-drying, keeping capital and operating cost low.
উপসংহার
Producing egg trays through a pulp-molding production line offers a clear, mature, eco-friendly, and efficient manufacturing solution.
By converting waste paper into pulp, forming it with specialized molding machine molds, and completing the process with drying, hot-pressing, and automated packing, the final result is strong and practical paper egg trays or pulp trays.
This workflow not only maximizes resource utilization but also allows flexible adaptation to different markets and customer requirements through adjustable molds and production capacities.
