AI Technical Summary
Lutein is extremely sensitive to high temperatures. Direct high-temperature heating and drying will accelerate its oxidation and decomposition, leading to a significant decrease in its content.
This drum-type baking machine uses a preheating chamber and a heating chamber for staged heating. The preheating chamber preheats the material to avoid direct exposure to a high-temperature environment. A three-way solenoid valve is used to regulate the air volume. Combined with a drive motor and belt pulley transmission, the drum turns the material. Temperature and humidity sensors monitor the temperature and humidity, and a transparent observation door and exhaust pipe ensure uniform heating and drying environment.
It reduces the oxidative decomposition of lutein, improves the retention rate of lutein, enhances heating efficiency, and creates a dry environment by promptly addressing problems through real-time monitoring and observation, thereby reducing the probability of motor failure.
