Pulp-molded products have gained popularity in the packaging industry due to their advantages in recent years, such as diverse sources of raw materials, an environmentally friendly production process, and recyclability. With advancements in pulp molding equipment technology, fully automatic egg tray production lines from AGICO have achieved efficient production, significantly lowering costs compared to other companies’ equipment.

AGICO integrates industry practices and technical characteristics to analyze the core processes and technical features of fully automatic eggtray production lines for sale, and customer can choose egg tray production lines of various capacities (1000 pcs/h ~ 10000 pcs/h) from AGICO.

Key Processes of Fully Automatic Egg Tray Production Line 

Pulping System – Waste Paper Regeneration and Precise Control 

• Raw material processing: Waste paper (such as old newspapers, cartons, etc.) serves as the base material, with impurities removed after crushing and screening to ensure pulp purity. 
• Slurry optimization: Environmentally friendly additives, such as waterproofing agents, are added while fibers are dispersed using a deflaker. The concentration is automatically adjusted with an accuracy of 0.01% to ensure slurry homogeneity. 
• Closed-loop slurry supply: The slurry is transported to the molding section through an intelligent pipeline system with no human intervention.  

 Molding System – Vacuum Adsorption and High-Speed Production 

• Mould technology: Porous metal molds are utilized to vacuum absorb the slurry, forming a wet blank, with independent adjustment of the slurry absorption time to meet differing product thickness requirements. 
• High efficiency: The rotary drum forming machine can produce 20 boards per minute, with the moisture content of the wet billet stabilizing at 75%-80%. 

Drying System – Multi-Layer Drying and Intelligent Temperature Control 

• Energy-saving design: The thermal efficiency of the multi-layer drying line reaches 90%, resulting in energy consumption that is 24% lower than that of traditional single-layer equipment. Exhaust gas recycling minimizes carbon emissions. 
• Dynamic control: Drying parameters are automatically matched according to product thickness and humidity, accurately managing moisture content at 69% and preventing yellowing or drying issues.

Stacking and packaging system – automated sorting and packaging

Intelligent sorting: Photoelectric sensors automatically remove unqualified products, and robotic arms stack and pack them according to the set quantity, with a yield rate of over 98% .

Technical advantages of fully automatic production line

1. Efficiency and automation

• Continuous operation: 24-hour continous production, with an average daily production capacity of 100,000 pieces , 40% higher efficiency than semi-automatic lines .
• Mold self-cleaning: Automatically clean the mold in each cycle, reducing downtime by 50% and ensuring product consistency.

2. Energy saving and environmental protection

• Recycling of waste paper: 100% recycled pulp is used to reduce raw material costs and conform to the concept of circular economy.
• Multi-energy adaptation: Supports multiple heat sources such as natural gas and steam, allowing enterprises to flexibly choose low-cost energy.

3. Precise quality control

• Fiber homogenization: The deflaker and multiple filtration ensure the slurry is uniform and the compressive strength of the finished product is increased by 30% .
• Closed-loop quality: Full data monitoring from molding to drying, real-time adjustment of process parameters to reduce human errors.

How to Select Fully Automatic Production Lines by Capacity

1. Limitations of large egg tray production lines

• Lack of flexibility: A single slurry supply system is difficult to adapt to the needs of multiple varieties, and mold adjustment depends on the overall speed, which limits efficiency.
• Low drying efficiency: Differences in product thickness lead to compromises in drying parameters, and energy utilization drops by 15%-20%.
• Complex management: When multiple specifications of products are mixed in production, the machine needs to be shut down for adjustment frequently, and failures may affect the operation of the entire line.

2. Competitiveness of small fully automatic egg tray production lines

• Flexible adaptation: independent slurry supply and modular design support small batch production of multiple categories, and mold switching only takes 30 minutes.
• Outstanding cost-effectiveness: the price of domestic equipment is only 1/3 of that of imported equipment. For example, Hong Kong Baoda Company uses domestic production lines to achieve an annual output of 5,600 tons. All products are exported and the quality is comparable to international standards.
• Energy efficiency optimization: Optimize drying parameters for a single category, and reduce energy consumption by 10% compared with large-scale lines.

3. Applicable scenarios of semi-automatic production lines

• Low-cost entry: suitable for start-ups, with low initial investment, but it relies on manual sequence transfer and the yield rate fluctuates greatly.
• Small-scale trial production: Flexible process adjustment, suitable for customized orders, but long-term operating efficiency is not as good as fully automatic lines.

Future Trends Predict – Intelligent and Customized Upgrades

IoT integration: Remote monitoring and fault warning systems reduce the difficulty of operation and maintenance and improve the stability of the production line.

Flexible manufacturing: Develop multiple pulp supply systems and independent drying modules to solve the problem of mixed production of multiple varieties.

Deepening of green technology: exploring biomass energy and low-temperature drying technology to further reduce carbon emissions.

The fully automatic egg tray production line has become the core driving force for the upgrading of the pulp molding industry, it has advantages of highly coordinated processes, industry-leading energy consumption, and precise and reliable quality control. Customers need to choose suitable fully automatic or semi-automatic solutions based on product type, scale and market demand. In the future, with the breakthrough of intelligent and flexible technologies, AGICO will promote the industry to continue to develop pulp molded production lines in the direction of high efficiency, low carbon and high added value.
