Packaging Industry Drying Tunnel Furnace

The Packaging Industry Drying Tunnel Furnace is a continuous hot air circulation heating system specially designed for rapid drying and curing of surface coatings, printing inks, adhesives, and heat shrink packaging materials.The equipment uses conveyor belts or mesh belts to continuously transport materials, allowing products to undergo uniform drying inside a constant-temperature tunnel. It is a key drying system widely used in large-scale packaging production lines.

FAQ

Q1: What types of packaging materials are suitable for this tunnel furnace?

A1:It is suitable for paper packaging, various plastic films (PE/PP/PET), metal cans, glass bottles, and composite packaging materials.

Q2: How does the equipment prevent packaging materials of different thicknesses from overheating and deforming?

A2:The equipment adopts a multi-zone independent temperature control system, allowing precise adjustment of temperature settings and conveyor speed for different materials and thicknesses.

Q3: Which heating method is the most energy-efficient for the drying tunnel furnace?

A3:Infrared heating provides high thermal efficiency. When combined with a hot air circulation system, it can further reduce heat loss and improve overall energy utilization.

Q4: What is the temperature resistance of the conveyor belt?

A4:The standard conveyor belt is made of PTFE (Teflon) mesh or stainless steel material. It can normally withstand temperatures above 260℃, fully meeting the requirements of packaging drying processes.

Q5: Can the length and width of the tunnel furnace be customized according to the factory layout?

A5:Yes. The furnace length, inlet width, and material passing height can all be fully customized according to production capacity, product dimensions, and available installation space.
