Chopped Strand Fiber Drying Tunnel Oven
Category：Tunnel Oven Production Line
Introduction
The Chopped Strand Fiber Drying Tunnel Oven is a continuous industrial drying system specially developed for glass fiber chopped strands, rock wool, slag wool, and other fiber-based products. The equipment adopts a tunnel structure with a conveyor system to carry materials. Through precisely controlled circulating hot air penetration, it achieves efficient and uniform moisture removal while maintaining fiber structure integrity and stable product quality.
Applications
Fiber Treatment:
Used for drying surface sizing agents on chopped glass fibers and carbon fibers.
Mineral Wool Drying:
Applied for curing and dehydration of rock wool and slag wool blocks or mats.
Composite Materials:
Used for continuous drying of fiber composite substrates such as needled felt and nonwoven fabrics.

Features
Uniform Air Penetration:
The equipment adopts an independent airflow channel design, allowing hot air to penetrate the material layer from both upper and lower directions, effectively solving the problem of insufficient drying in the middle layer of fibers.
Independent Temperature Zone Control:
The entire drying line is divided into multiple independent temperature zones, supporting precise setting of heating, soaking, and cooling process curves.
Energy-Efficient Insulation:
The chamber uses thickened high-density aluminum silicate fiber insulation, resulting in low external surface temperature and minimal heat loss.
Anti-Contamination Design:
Built-in multi-layer high-precision filters prevent fiber debris from blocking airflow channels or causing airborne contamination.
