With the rapid growth of large-scale poultry farms, egg production volumes have expanded significantly. Fresh eggs must serve not only local markets but also distant distribution. Poor packaging and improper transport lead to breakage and spoilage ??unnecessary losses for operators. Better packaging and transport technology reduces losses and improves profitability.
I. Fresh Egg Packaging Technology
Selecting the right packaging materials is the first priority. Materials should be durable, economical, and convenient. Options include wooden crates, corrugated fiberboard boxes, plastic crates, egg trays, and matching egg cartons.
1. Wooden Crates and Corrugated Boxes
Wooden crates and corrugated boxes must be sturdy, clean, and dry. The recommended capacity is 300 to 500 eggs per box. Filling materials must be dry, clean, and odor-free ??chopped wheat straw, rice straw, sawdust, or rice husks work well. Never use damp or moldy filling materials.
Packaging procedure:
- Spread a 5–6 cm layer of filling material on the box bottom, slightly thicker at the corners
- Place one layer of eggs with the long axis consistently oriented ??all aligned neatly, never mixed orientations
- Cover with a 2–3 cm filling layer, then another egg layer
- Alternate filling and egg layers until the box is full
- Top the final layer with 5–6 cm of filling material before closing
Wooden crate lids should be nailed securely. Corrugated box lids must be closed tightly and the box tied firmly with rope. Finally, label with product name, weight, and apply “This Side Up” and “Handle with Care” markings.
2. Egg Trays and Egg Cartons
Egg trays are specialized plastic trays with individual compartments. Eggs are placed small-end down and large-end up ??an inverted position. Each compartment holds one egg, with 30 eggs per tray. Trays can be stacked without crushing the eggs underneath. Egg cartons are corrugated or plastic boxes designed to work with these trays.
This method saves time, simplifies counting, reduces breakage rates, and allows trays and cartons to be disinfected and reused.
II. Fresh Egg Transportation
During transport, minimize transit time and reduce intermediate handling. Select the appropriate transport mode based on distance and road conditions. Follow the three principles of speed, stability, and gentleness:
- Speed ??Minimize time in transit
- Stability ??Reduce vibration; choose smooth-riding vehicles
- Gentleness ??Handle boxes carefully during loading and unloading
Additional precautions:
- Protect egg boxes from direct sunlight and rain
- Insulate against cold and freezing in winter; prevent heat-related spoilage in summer
- Transport vehicles must be clean and dry
- Vehicles previously used for pesticides, ammonia, kerosene, or other toxic and odorous substances must be disinfected, cleaned, and verified odor-free before transporting eggs
