Process Flow

1. 201A Egg Washing Machine Main Unit:

Egg placement: Workers manually place the eggs on the conveyor rollers, after which the eggs are automatically sorted and transported to the disinfection section of the egg cleaning machine.

Light Inspection: The LED light inspection device is installed below the single-row rollers. As the eggs pass through the rollers, human eyes use light transmission to detect and identify damaged eggs, eggs with abnormal shapes, as well as eggs that are defective due to issues such as black cores or mold.

Disinfection Spraying: For the purpose of food safety, the disinfection spraying system automatically sprays a food-grade cleaner or disinfectant (provided by the customer) on the surface of the eggs.

Cleaning: The eggs are placed into an egg cleaning machine, where they are sprayed with warm water and brushed before entering the air-drying system. The water heater is provided by the customer. For food safety reasons, the water used for cleaning eggs cannot be reused. The water consumption is approximately 0.5 cubic meters per hour, and the amount of water used can be adjusted according to the degree of dirt on the eggs.

Air Drying: The air-drying brush at the rear of the egg cleaning machine removes most of the water from the eggs, and the remaining droplets are dried by the strong airflow generated by the fan, achieving a drying efficiency of up to 95% (depending on the local environmental humidity).

Spraying: Apply food-grade white mineral oil onto the surface of the dry and clean eggs. A uniquely designed spraying device atomizes the white mineral oil into particles smaller than 0.05mm, which then adhere to the eggshell. These particles are quickly absorbed by the eggshell’s capillaries, forming a protective layer that helps reduce the loss of moisture inside the egg and prevents the entry of external bacteria. (The air compressor used for spraying is provided by the customer.)

Fuel injection effect

Inkjet Printing: High-resolution inkjet printers that deliver clear prints without ink smudging; food-grade ink, SGS-certified, suitable for use in supermarkets and stores; touchscreen operation, easy to use, and equipped with a full range of features.

2. 604B Egg Conveyor: Connects the grading machine and the cleaning machine, and is equipped with ultraviolet sterilization functionality. Eggs are passed through an area containing ultraviolet sterilization lamps to minimize the number of bacteria on the eggshell surface.

3. 102B Egg Grading Machine Main Unit:

Light Inspection: The LED light inspection device is installed below the three rows of rollers. As the eggs pass through the rollers, human eyes use light transmission to detect and identify damaged eggs, eggs with abnormal shapes, as well as eggs that are defective due to having black cores or being moldy.

Classification: The mechanical weighing system uses the principle of levers to adjust the weights, sorting eggs into up to 5 different grades based on their weight with a precision of ±1 gram.

Manual egg collection and packaging (egg collection table): Eggs that have been graded are rolled onto stainless steel egg-catching plates in different compartments, where they are then collected and packaged by hand.
