How Does an 8 Side Egg Tray Machine Work? Structure and Production Process
A máquina de bandejas de 8 lados consiste principalmente em sistema de polpa, sistema de formação, sistema de secagem e sistema de embalagem.
8 Side Egg Tray Machine Structure
An Máquina de bandeja de ovos de 8 lados uses an octagonal rotary drum as its forming core. Each of the eight drum faces carries a row of aluminum forming molds, and the whole drum rotates continuously through the pulp vat, vacuum forming station, and ejection zone.
The mold layout depends on the model:
- SL-4000-4×8: 4 molds per side × 8 sides = 32 forming molds
- SL-5000-5×8: 5 molds per side × 8 sides = 40 forming molds
- SL-7000-6×8: 6 molds per side × 8 sides = 48 forming molds
This high-density layout is what allows the machine to reach 4,000–7,000 pieces per hour. The drum is driven by a heavy-duty gear system with wear-resistant bearings. A vacuum pump, air compressor, PLC control cabinet, and transfer conveyor are integrated into the same frame.
The complete production system also includes:
- Sistema de polpa – hydrapulper, pulp pump, and consistency regulator
- sistema de moldagem – 8-sided rotary drum with vacuum molds
- Sistema de secagem – sun drying racks, brick kiln, or multi-layer metal dryer
- Packing system – hydraulic press and strapping unit
Processo de Produção
Step 1: Pulp Preparation
Waste paper, cardboard, or pulp board is loaded into the hydrapulper with water at a ratio of about 1:4. The blades run for 15–20 minutes until the mixture becomes a smooth fiber slurry. The pulp concentration is adjusted to 2–3% before it is pumped into the machine’s pulp tank.
Step 2: Mold Immersion and Vacuum Forming
As the 8-sided drum rotates, each mold face dips into the pulp tank one after another. A vacuum pump draws pulp fibers onto the mold screen, shaping the wet tray inside the mold cavity. Because eight sides are working in sequence, forming never stops.
Step 3: Dewatering
After leaving the pulp tank, the formed tray stays on the rotating drum for a few seconds. Gravity and vacuum suction remove excess water. The wet tray still contains about 50–60% moisture when it reaches the ejection point.
Step 4: Automatic Transfer
At the transfer position, the vacuum is released and positive air pressure blows the wet tray off the forming mold onto a transfer conveyor or a transfer mold. The empty mold then continues to the next forming cycle.
Step 5: Drying
Wet trays move into the drying system. Depending on the setup, this can be:
- Sun drying – trays dry on racks in open air for 2–3 days
- Brick kiln dryer – hot air at 80–120°C dries trays in 45–90 minutes
- Multi-layer metal dryer – automatic belt dryer with the smallest footprint
Moisture is reduced from 50–60% to below 12%.
Step 6: Stacking and Packing
Dried trays are stacked and fed into a hydraulic packing machine. The press compresses the stack by 30–40% and straps it for transport. This reduces shipping volume and warehouse space.

How to Make Egg Trays with an 8 Side Egg Tray Machine?
As matérias-primas são principalmente polpa de palha, polpa, polpa de bambu, polpa de madeira, papelão reciclado, papel de caixa de papel reciclado, papel branco reciclado, resíduos de polpa de cauda de fábrica de papel, etc. A matéria-prima tem uma ampla gama de fontes e é fácil de coletar. A máquina de bandejas de ovos é a máquina principal para a linha de produção de bandejas de ovos.
Alimentando a polpa na piscina de polpa para a máquina de moldagem. A polpa é absorvida pelo sistema de vácuo, e a polpa é moldada pelo molde no equipamento. A água é absorvida e transportada de volta para a piscina de polpa através da bomba de vácuo. A água pode ser reciclada.
Após o molde absorver a lama, o molde de transferência é descarregado através do compressor de ar. O produto acabado é soprado do molde de formação para o molde de transferência, e então é enviado pelo molde de transferência.

Perguntas frequentes
What is the difference between a 4-side and an 8-side egg tray machine?
A 4-side machine has four forming faces on the rotary drum and is ideal for 2,000–3,000 pcs/h. An 8-side machine has eight forming faces and higher mold density, making it suitable for 4,000–7,000 pcs/h.
How many workers are needed to run an 8 side egg tray machine?
A complete 8-side line normally needs 3–5 workers per shift. One operator monitors the control panel, one handles raw material feeding, and the rest manage drying and packing.
What is the power consumption per 1,000 trays?
Power use is approximately 0.0125–0.013 kWh per tray, or 12.5–13 kWh per 1,000 trays. Drying fuel is calculated separately based on coal, diesel, gas, or electricity choice.
Can the 8 side machine produce products other than egg trays?
Yes. By changing molds, the same machine can produce fruit trays, shoe trays, wine bottle trays, electronic component trays, and disposable food containers.
How much floor space does an 8-side egg tray production line need?
The forming machine itself needs about 30–50 m². With a brick kiln dryer, the total workshop area is usually 600–800 m². A multi-layer metal dryer reduces this to 200–300 m².
What is the typical delivery time after placing an order?
Standard models need 20–30 working days. Custom voltage or special mold designs may add 5–10 working days. Sea shipping time depends on the destination port.
What spare parts should be kept in stock?
We recommend keeping mold screens, vacuum pump seals, air compressor filters, bearings, and conveyor belts in stock. These parts wear gradually and are easy to replace.
Can the machine run in hot and humid climates?
Yes. The electrical cabinet is waterproof and dustproof. Stainless steel parts resist corrosion. In very humid areas, we recommend a metal dryer instead of natural sun drying.
