Factory Direct Egg Tray Packaging Machine
Factory Direct Egg Tray Packaging Machine
Egg tray packaging machines transform pulp-formed trays into stacked, ready-for-shipment units. They integrate forming, drying, counting, and bundling functions into a continuous line.
Key Technical Specifications
| Parameter | Value | Unit |
|---|---|---|
| Maximum throughput | 120 | trays/min |
| Tray size range (length) | 180 – 300 | mm |
| Tray size range (width) | 120 – 200 | mm |
| Installed power | 7.5 | kW |
| Electrical supply | 380 – 480 | V AC, 3‑phase |
| Machine footprint (L×W×H) | 2200 × 1100 × 1800 | mm |
These figures represent baseline performance; actual values adjust according to tray dimensions and material thickness.
Optional servo drives can increase positioning accuracy to ±0.5 mm for high‑speed lines.
Operating Principle
Material feeding begins at the pulp hopper where wet trays are conveyed on a mesh belt.
Infrared drying zones raise temperature to 80 °C, reducing moisture content to below 12 % before stacking.
A pneumatic pusher aligns trays into groups of ten, which are then banded by an ultrasonic welding module.
Customization Options
Customization focuses on mechanical interfaces and auxiliary functions that can be tailored without redesigning the core drive.
- Adjustable lane width from 100 mm to 350 mm to accommodate different tray formats
- Optional hot‑melt glue applicator for secondary carton sealing
- Integration of vision inspection for defect detection at 0.2 mm resolution
- Choice of stainless‑steel (AISI 304) or powder‑coated carbon steel frame
- Variable frequency drive (VFD) for independent speed control of drying and stacking sections
Applications
Egg producers benefit from reduced labor because the machine automates counting and bundling that previously required manual handling.
By maintaining consistent tray orientation, downstream palletizers experience fewer jams, increasing overall line efficiency.
The modular design allows installation in both new greenfield plants and retrofits to existing packing lines.
Quality Control & Testing
Each machine undergoes factory acceptance testing where throughput, moisture content, and seal strength are measured against ISO 22000‑aligned criteria.
Statistical process control monitors drying temperature uniformity, ensuring variation stays within ±2 °C across the belt width.
Final inspection includes a 2‑hour run‑test at full speed, after which a test report is supplied with the shipment.
Frequently Asked Questions
Yes, lane width, height, and overall footprint can be adjusted to match tray size and facility layout.
Tray dimensions, material grammage, desired output rate, and any auxiliary modules such as glue or vision.
Factory acceptance testing includes throughput verification, moisture analysis, seal tensile strength, and a 2‑hour endurance run.
Machines are wrapped in shrink film, placed on steel skids, and secured with corrosion‑resistant straps for container transport.
