Main Factors:

Material: cold plate for outer shell, with painting; stainless steel 304 for inner chamber, full welded;

Heating Source: Electrical heating, hot air recirculation

Conveyor: SS plate conveyor

Humanity Control: each section has exhausting fans, with convertor, fan speed adjustable.

PLC & HMI control

Other Information:

Airflow:
The oven uses either forced or natural airflow to ensure that the hot air comes into contact with the powdered material, allowing moisture to evaporate efficiently.
Drying Zones:
As the Larger tunnel oven,  it has multiple drying zones with different temperature settings depending on the material's sensitivity or required drying profile.

Energy Efficiency:
Depending on the model, these ovens can feature energy-saving technologies, such as recirculated air or heat recovery systems.

Automation:
Available for fully automated, allowing the adjustment of drying parameters based on real-time monitoring. Sensors can track humidity, temperature, and airflow to optimize the drying process.

End Product Quality:
Proper drying prevents the powder from clumping or losing quality, which is important for maintaining texture, flavor, or effectiveness (in cases of pharmaceuticals).
Benefits:
Continuous Production: Because of the conveyor system, the drying process can be continuous, leading to higher throughput.
Uniform Drying: The controlled environment ensures that the product is evenly dried.
