Fully Automatic Rotary drum type high-speed Egg carton Pulp molding production line

The equipment is designed for continuous wet blank forming and preheating of egg trays, combining molding, drying, and hot pressing processes into an integrated production system. With a four-sided drum-type molding structure and continuous conveying design, it supports efficient production of 10-egg and 12-egg cartons while maintaining consistent forming quality.

The system is suitable for automated egg tray production lines requiring stable output, controlled drying, and efficient use of production space.

Main Equipment Features

Four-Sided Drum Molding Structure: The molding template adopts a four-sided drum configuration, allowing continuous forming and improving production efficiency.

High-Speed Forming: The molding section operates at approximately 15 plates per minute, supporting stable continuous production.

Integrated Preheating and Drying: The system combines wet blank molding with preheating and drying to improve production continuity and finished product consistency.

Heavy-Duty Hot Pressing: The hot pressing section provides up to 30T of pressure to help achieve uniform forming and structural strength.

Flexible Heating Options: The drying system can use natural gas, LPG, or diesel according to the customer's available energy source and production conditions.

Efficient Circulation System: A 55KW circulation fan helps distribute heated air throughout the drying section for more uniform drying performance.
