How an Egg Tray Pulp Forming Machine Works

An egg tray pulp forming machine is specialized equipment that recycles waste paper into molded fiber packaging for eggs, fruits, and other industrial products. It operates using a vacuum suction method to create products through a series of automated steps.

A complete egg tray production line transforms waste paper into finished trays as follows:

1. Pulping: Waste paper (newspapers, cardboard, etc.) is fed into a hydrapulper, where it is mixed with water to break down into individual fibers. The result is a slurry, or pulp, which is stored in a tank.

2. Forming (Molding): The diluted pulp is pumped to the forming machine. A vacuum system on the back of a mold draws the pulp onto its surface, forming the shape of the egg tray.

3. Drying: The newly-formed, wet trays are conveyed into a drying system. This typically uses a multi-layer drying line to efficiently remove moisture and solidify the trays.

4. Stacking & Packaging: Once dry, the finished trays are automatically collected, stacked, and prepared for packaging by an automatic stacking system.

A key feature of the system is water recycling, which purifies and returns used water to the pulping process, significantly reducing waste and operational costs.

A Sustainable Investment

An egg tray pulp forming machine is an eco-friendly investment that aligns with sustainable waste management practices. The final products, made from recycled materials, are 100% recyclable and compostable, directly supporting a circular economy.

Key Components of a Production Line

A complete production line integrates several critical systems that work in harmony:

• Pulping System: Breaks down waste paper into a usable pulp mixture of water and fibers.

• Forming System: Uses a mold and vacuum to shape the pulp into wet trays.

• Drying System: Removes moisture from molded products using natural sunlight or a multi-layer drying line.

• Stacking and Packaging System: Automatically collects, counts, and packages the finished trays.

• Vacuum and High-Pressure Water Systems: Provide suction for forming and high-pressure spray for cleaning molds.

• Air Pressure System: Assists in the automatic transfer and demolding of products.

Key Types: Find Your Perfect Match

Choosing the right type of forming machine depends on your production goals.

• Rotary Drum Machine: Ideal for continuous, high-volume production of standard products. It can produce up to 6,000–7,000 trays per hour. The initial investment is higher.

• Reciprocating Machine: Suited for smaller-scale, versatile production lines that require frequent mold changes for different products. It typically produces up to 1,500 trays per hour. The lower output is balanced by lower upfront costs.

• Turn-Over (Flip) Machine: A less common, medium-scale option that uses a “flipping” mechanism to transfer wet products from one mold to another, offering a middle ground in production efficiency.
