This Hot Air Circulating Drying Sterilizing Tunnel Oven consists of three sections : Pre-heating section, High temperature drying section and Cooling section.

The Pre-heating section is composed of fan, dehumidifier fan and filter.

The High temperature drying section is composed of heat resistance fan, electrical heater,  and high temperature filter,  forming a circulation system inside the oven, ensures good temperature uniformity and high efficiency. The fan supplies heated air, passing through filter, circulated hot air continuously dries and sterilizes the bottles on the moving mesh belt(heating temperature can be adjustable from 50-350℃) .

The Cooling section is composed of fan, cooler, filter and air exhaust motor, forming a full circulation system to cool bottles, so that the bottle discharge port's temperature stays between 25~30℃.The whole process is under class 100 laminar flow protection with DOP test port and several temperature measuring ports. And this Sterilizing Tunnel Oven adopts PLC control, man-machine interface operation, the temperature is displayed by the temperature controller, set and recorded automatically, fully comply with GMP standards.

This machine can be used alone or combined with ultrasonic washing machine and filling capping machine to form a production line. The sterilizing speed for this machine is about 100~600 bottles/min adjustable.
