What is Pulp Eggtray Making Machine

The pulp egg tray machine is always refers to an automated eggtray production line designed specifically for producing paper egg trays. Its core principle is to transform recycled waste paper into environmentally friendly packaging. Unlike traditional plastic products, pulp egg trays are fully biodegradable in the natural environment, while ensuring both protection and economical transportation. The complete eggtray production line utilizes 4 collaborative systems—raw material pulping, vacuum forming, thermal drying, and auto packaging—to achieve fully automatic production. The main process can be seperated into pulp making and eggtray forming.

Auto and Semi-Auto Egg Tray Production Line Options

1. Fully automatic egg tray production line: Model ZMDT 5×12, output reaches 5000-6000 eggs/hour, power 4 kW. This line has a high degree of automation, greatly reducing human intervention from raw materials to finished product, making it suitable for large-scale production.
2. Semi-automatic egg tray production lines: the DT 4×4 egg tray machine, have an output of 2200-2500 pcs/h and a power of 3 kW. This is a good choice for companies with relatively small production scales or limited budgets.
3. Rotary egg tray machine: DT4×8 8-sided rotary egg tray machine as an example, the output is 3500-4500pcs/h, 40 molds, and 4 kW power. Rotary egg tray machines have high production efficiency and can achieve continuous production.

Eggtray Production Line Work Flow:

The work flow of eggtray production line is similar to a sophisticated ecological cycle:

Raw material selection: Use waste paper as raw materials, which are widely available and low in cost, and in line with environmental protection concepts of recycling of waste paper resources.

1. Turn Waste Paper to Pulp
   Waste paper, such as old newspapers, magazines, and cartons, is shredded and screened, then mixed with chemical additives to create a slurry of a desired consistency, ready for molding. The recycled paper is hydraulically shredded to form a suspended fiber slurry. Engineers must precisely control the slurry concentration and fiber length, which directly determine the toughness of the final product.
2. Pulp Molding -Eggtray Forming
   The pulp slurry is injected into a mold with vacuum adsorption holes through vacuum action. The moisture is instantly extracted and the fibers are interwoven on the surface of the egg tray mold to form the prototype of the egg tray. Make the pulp evenly adhere to the special forming mold to form a wet product, and then transfer it to the drying system This process determines the shape and initial quality of the egg tray. This step precisely controls the thickness curve and structural density of the product, just like 3D printing.
3. Dehydration and Strengthening Process
   The moist embryo is subjected to strong mechanical squeezing, just like a sponge being wrung out, removing more than 60% of the moisture to form basic strength and prepare for high-temperature drying.
4. Thermal drying- Civil Engineer Drying or Metal Drying
   utilizes heat sources such as gas, diesel, steam, and thermal oil to dry the wet product after forming, ensuring the egg trays possess sufficient strength and stability. In a multi-layered circulating drying tunnel, hot air drives moisture evaporation, while infrared monitors adjust the temperature profile in real time, ensuring each egg tray is evenly dried without deformation.
5. In The Final Stage Of Finishing
   An automatic trimming machine removes burrs, a visual inspection system scans for defects, and workers stacks and packages qualified products in a honeycomb structure. Then it is manually packaged by a packaging machine for easy transportation and sales.

Highlights of Egg Tray Production Technological Advantages

Modern egg tray production equipment has broken through traditional limitations:

• Intelligent Control: PLC control system monitors 200+ operating parameters in real time and automatically compensates when mold temperature fluctuates by 0.5 °C.
• Green Recycle Design: 80% of the heat energy of drying exhaust gas is recycled, and the water circulation system reduces the water consumption per ton of product to less than 5 tons.
• Flexible Deformation Capability: Modular mold design supports switching production of egg trays, fruit trays, and electronic component trays within 2 hours.
• Ultra-long Service Life design: the forming mesh adopts silicon carbide coating, and its service life is more than 3 times that of ordinary parts.

Pulp Mold Trays Applications Fields Expansion Map

From farms to high-tech factories, the reach of pulp molded trays continues to expand:

• Egg transportation: Special trough design can withstand 30 kg of pressure, reducing the breakage rate to 0.3%.
• Fresh Produce Logistics Network: Kiwifruit trays feature an anti-mildew coating, extending the fruit’s shelf life by 15%.
• Precision instrument protection: Military-grade pallets incorporating bagasse fiber pass ISTA 3A transportation testing
• Food packaging revolution: Chocolate holders made from edible-grade paper pulp appear in high-end supermarkets.

What Makes AGICO a Top Pulp Molding Machinery Manufacturer

1. Capacity dimension: Medium-sized equipment produces 1.5 million pieces per month, and consumes electricity equivalent to 30 household air conditioners.
2. Quality verification: A standard 30-piece pulp egg tray can support a vertical load of up to 25kg, enough for six-layer stacking and transportation. With a thicker design, the load capacity can be increased to 40kg, and no fibers fall off the corners.
3. Hidden costs: A certain model metal drying system uses variable frequency technology, and the electricity savings over three years can recover 20% of the equipment price.
4. Service depth: AGICO provides remote diagnosis service, shortening fault response time to 4 hours.
