Operating an egg tray machine correctly is the foundation of efficient egg tray production. Whether you are a startup entrepreneur or an established pulp molding factory, understanding the proper operating process can significantly improve productivity, reduce failure rates, and extend machine lifespan.

In this guide, we will explain how to operate an egg tray machine step by step, from raw material preparation to finished tray stacking, helping you achieve stable, efficient, and profitable production.

Prepare Raw Materials and Pulping System

Before starting the egg tray making machine, the first step is to prepare the pulp.

Raw Materials

  • فضول کاغذ
  • Old cartons
  • اخبارنامہ
  • Office paper
  • Books

These materials are soaked and pulped into a fiber slurry.

Pulping Process

  • Put waste paper into the shredder.
  • Add water to form pulp slurry.
  • Adjust pulp concentration (usually 1–2%).
  • Filter impurities for smooth molding.

A stable pulping system ensures uniform fiber distribution, which directly affects egg tray strength and surface quality.

Mold Forming Operation of Egg Tray Machine

This is the core operating stage of the egg tray machine.

Forming Process

  • The molding mold dips into pulp slurry.
  • Vacuum suction absorbs fiber onto the mold surface.
  • The wet egg tray is formed automatically.

Key operating tips:

  • Maintain stable vacuum pressure.
  • Ensure slurry tank level consistency.
  • Keep the mold surface clean for smooth tray forming.

Automatic Transfer and Demolding System

After forming, the wet egg trays are transferred to the transfer mold.

  • Vacuum switches from forming mold to transfer mold.
  • Egg trays detach smoothly without damage.
  • Automatic stacking begins.

This automated transfer ensures:

  • High production speed
  • Uniform tray shape
  • Reduced labor involvement

Drying Operation of Egg Tray Production Line

Drying is a critical stage for egg tray strength and appearance.

Drying Options

  • Natural drying (low investment, weather dependent)
  • Brick kiln drying line
  • Metal multi-layer dryer
  • Hot air circulation drying tunnel

Drying Temperature Control

  • Recommended drying temperature: 120–180°C
  • Stable airflow ensures even drying

Efficient drying improves tray hardness and storage stability.

Hot Pressing and Stacking (Optional)

For premium egg trays, a hot pressing system can be added:

  • Smooth surface
  • Uniform thickness
  • Better appearance
  • Higher stacking stability

Finished trays are then stacked and packed.
