Fully Automatic Roller-Press Pallet Production Line
· Product Overview
The fully automatic roller-type tray production line comprises a pulping system, a forming system, a drying system, a stacking system, a vacuum system, a high-pressure water system, and a compressed air system, and is used to manufacture egg trays, fruit trays, and other similar products. It utilizes waste paper such as used newspapers, used cardboard boxes, office paper, and trimmings as raw materials; after hydraulic pulping, screening, and water addition, the material is adjusted to a specified consistency to form a pulp slurry. This slurry is then fed into a specialized metal mold via the forming system, where vacuum adsorption shapes it into a wet blank. The blank is subsequently dried on the drying line and finally stacked to complete the production process.

Product Details

The main production system consists of a roller-type forming machine, a six-layer drying line, and a stacking machine. The production line features high capacity and a high degree of automation, reducing labor costs, while the multi-layer, high-efficiency drying line helps conserve natural gas.
The specific parameters are as follows:
| Model | ET12000 |
| Production Line Composition | Molding System: Molding System: 12 faces (6-face molding + 6-face transfer) Drying System: 6-Layer Oven Stacking System: Four-Channel Stacker (with Automatic Counting Function) |
| Molded template dimensions (mm) | 1600x400 |
| Design capacity of the production line | 12,000 pieces/hour |
| Molding method | Roller-type slurry suction forming |
| Molding cycle time | 50 boards per minute |
| Mold Layout | One set of 4 pieces (arranged according to a 30-egg tray) |
| Product height | ≤70mm |
| Heat source | Natural gas, heat-transfer oil, LPG, LNP, or steam (if steam is used, the oven will be designed for scalable capacity). |
| Control Method | PLC + touch screen |
| Remarks | The above parameters are provided for reference only. As technology continues to evolve, the relevant data will be updated on an ongoing basis. |

1. High output, high flexibility, and high return on investment
With a production capacity of 12,000 units per hour, it can simultaneously produce two types of slurry-based products, meeting multi-color requirements.
2. High degree of automation
Only 4–5 operators are required.
3. Energy Conservation
Multi-layer high-efficiency drying lines, combined with waste-heat preheating recovery and roll-forming transfer technology, effectively reduce energy consumption.

The following data represent the standard configuration for this production line; however, the configuration can be customized to meet the specific requirements of the customer.
| Reference model | Production capacity | Occupying land | Personnel | Using electricity | Natural gas consumption |
| ET12000 | 12,000 pieces/hour | 66 times 24 rice , height ≥ 5 rice | 4–5 people per shift | 425 kilowatt-hour | 227 m³/ hour |
