Egg tray dryer structure analysis and efficiency improvement methods
In the process of egg tray production, the moulded egg tray contains high moisture and must be dried efficiently before entering the packaging process. Egg tray dryer, as a key supporting equipment, is directly related to the production efficiency and quality of the finished product.
So, what is the structure of the common egg tray dryer composed of? What are the methods to improve the drying efficiency?
The basic structure of the egg tray dryer
Different types of egg tray drying equipment vary slightly in structural design, but mainly include the following core parts:
- Transmission System
The wet egg trays are output from the moulding machine and smoothly transported to the drying area by means of chains, rollers, or conveyor belts. The conveyor speed can be adjusted to suit different capacity requirements. 2. - Hot Air Circulation
The heat source generates hot air through a combustion chamber or heater, and the fan sends it evenly into the drying channel. Some systems are equipped with a hot air recovery function to enhance the utilisation of heat energy. - Drying Tunnel
This is the core area of the egg tray drying process and is usually constructed as a multi-layer or single-layer structure with thermal insulation to ensure that no heat is lost. The internal design has a wind guide plate to optimise the distribution of hot air flow and improve the drying uniformity. - Control Panel
Contains a temperature controller, a conveying speed regulator, an alarm, etc., to ensure the stable operation of the equipment.

How to improve the efficiency of egg tray drying?
- Optimise the structure of the heat source
Choose burners with high thermal efficiency and match them with energy-saving insulation materials. A hot air circulation system can be considered to avoid energy waste. - Maintain a stable temperature and wind speed
Reasonably set the drying temperature and ventilation speed to avoid uneven drying or egg tray deformation caused by a large temperature difference. - Adjust the speed of the conveyor belt
According to the thickness and moisture content of the egg tray, set the appropriate drying time. In general, the drying time is 15~25 minutes. - Segment control temperature zone
Divide the drying channel into preheating zone, drying zone, and cooling zone. Each temperature control is designed to improve drying efficiency while reducing the risk of egg tray cracking. - Regular maintenance of the equipment
Clean the air ducts, check the combustion of the heat source, and maintain the conveyor system. Ensure efficient operation of the equipment and reduce the failure rate.
