Pass Through Tunnel Oven
Category：Tunnel Oven Production Line
Introduction
A Pass Through Tunnel Oven is an industrial-scale continuous drying and heating system. It allows materials to continuously pass through the heating tunnel via conveyor belts, mesh belts, or overhead chain conveying systems. The equipment adopts heating methods such as far-infrared radiation, hot air circulation, or microwave heating to achieve rapid and uniform baking, drying, curing, or heat treatment of materials.
Applications
Electronic & Electrical Industry:
Used for PCB curing, electronic component drying, and thermal hardening after dispensing processes.
Metal & Plastic Products:
Applied for surface coating drying, silk-screen ink drying, and plastic moisture removal.
Food Industry:
Used for baking bread and pastries, roasting nuts and snacks, and dehydrating seafood and meat products.
New Energy Industry:
Used for lithium battery electrode drying and curing processes after photovoltaic module lamination.
