Oem Egg Tray Filling And Packing Machine

OEM Egg Tray Filling and Packing Machine

This machine integrates precise volumetric filling with automated tray placement and sealing for egg packaging lines. It is designed to handle standard poultry egg trays ranging from 20 to 30 cells, accommodating weights from 45 g to 65 g per egg. The system operates at configurable speeds up to 120 trays per minute while maintaining fill weight variance below ±0.5 %.

Key Features and Functional Benefits

The filling station uses servo‑driven pistons with closed‑loop feedback, delivering repeatable volumetric discharge within ±0.2 ml per cycle. This precision reduces product giveaway and ensures consistent weight across trays.

Tray positioning is handled by a dual‑gripper mechanism that aligns trays to within ±0.5 mm before filling, minimizing misfeeds and jam incidents. The gripper force is adjustable from 15 N to 45 N to accommodate different tray materials.

After filling, a heat‑seal bar applies a polyethylene film seal at 180 °C with a dwell time of 0.8 s, producing a seal strength of at least 2.5 N/mm. The sealing station includes a cooling block that reduces film temperature to below 50 °C before discharge.

An integrated sensor suite monitors tray presence, fill level, and seal integrity in real time. Fault detection triggers a reject conveyor that removes non‑conforming trays at a rate of up to 30 trays/min without stopping the main line.

The machine frame is constructed from 304 stainless steel with a brushed finish, providing corrosion resistance suitable for wash‑down environments (IP66). All contact surfaces are designed for CIP (clean‑in‑place) with spray balls delivering 2 L/min at 2 bar.

Applications in Poultry Processing

Egg handling requires gentle transfer to prevent shell cracking while maintaining high throughput to meet packing house demands. The machine’s low‑impact gripper and synchronized tray feed reduce mechanical shock, preserving egg quality during high‑speed operation.

Because the filling volume is adjustable via the HMI, the same equipment can process different egg grades (small, medium, large) by changing the target weight setting, eliminating the need for multiple dedicated lines.

The sealed tray output is compatible with downstream cartoners and palletizers, allowing a continuous flow from collection to retail‑ready packaging. The system’s modular design enables installation alongside existing conveyors with minimal line reconfiguration.

Customization Options

Tray material: food‑grade polypropylene, recycled PET, or pulp‑based board.
Cell count: 18, 20, 24, 30 cells with adjustable pocket depth.
Packing format: single‑layer trays, stacked trays, or shrink‑wrapped bundles.
Upstream integration: rotary egg accumulator, vibratory feeder, or gravity chute.
Downstream integration: label applicator, date coder, or case packer.
Cleaning system: manual spray nozzles, automatic CIP skid, or UV‑sterilization tunnel.

Quality Control and Testing

Each machine undergoes a factory acceptance test that includes a 24‑hour run at rated speed, measuring fill weight deviation across 10 000 trays. The collected data must show a standard deviation below 0.3 g to be approved for shipment.

Material certificates for stainless steel and food‑contact polymers are provided with every order. Critical components such as pistons and seals are inspected for dimensional tolerances using a coordinate measuring machine (CMM) with a repeatability of 2 µm.

Before delivery, a functional safety audit verifies that emergency stop circuits achieve a stop time under 150 ms and that guarding meets ISO 13857 requirements. Documentation includes a risk assessment report and a CE conformity declaration.

Frequently Asked Questions

Can the machine be adapted for non‑standard tray dimensions?

Yes, the gripper arms and tray guides are adjustable; custom trays up to 350 mm × 250 mm can be accommodated after a feasibility review.

What information is required before quotation?

Target egg weight range, tray specifications (material, cell count, dimensions), desired line speed, and any required upstream/downstream interfaces.

How is quality inspected during production?

In‑process checks include weight sampling every five minutes, seal strength testing on a random sample of 1 % of output, and visual inspection for tray defects using a 5 MP camera system.

What packaging methods are available for the finished trays?

Finished trays can be conveyed directly to a carton erect‑and‑seal unit, placed into shrink‑wrap tunnels, or stacked on pallets with inter‑layer sheets.

What is the typical production lead time?

Standard configurations ship within 8‑10 weeks after order confirmation; customized builds may extend to 12‑14 weeks depending on component availability.
