Tunnel oven is an oven that uses long box hot air circulation and far-infrared drying to dry. It is mainly aimed at the drying demand with high output and high efficiency.

Basic working principle: under the monitoring of the computer system, the bottles enter the preheating zone, high-temperature zone (temperature ≥ 5min) and low-temperature cooling zone of the tunnel oven along with the conveyor belt. The conveyor belt speed is stepless and adjustable, and the temperature monitoring system is set with paperless or paperless recording.

The whole process is always under the hundred level laminar flow protection.

The heating element of the tunnel oven is installed at the top of the oven to improve the thermal efficiency The oven is equipped with electrical control cabinet and temperature digital display control. It can be controlled in any constant temperature state. At the outlet, the material can be cooled by vertical laminar flow purification with a cleanliness of class 100 to make the material

In a strictly sterile and dust-free state. Aluminum silicate is used as insulation material in the insulation layer of the oven, with good insulation performance.
