Chopped Strand Fiber Drying Tunnel Oven

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.

Product 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.

Product Parameters

Product 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.

FAQ

Q1: How does the equipment adjust for chopped strands with different moisture contents?

A1:The conveyor speed can be adjusted through the variable speed motor, while hot air temperature and airflow volume in different temperature zones can be regulated to meet various drying requirements.

Q2: Can fiber debris cause fire hazards or block the airflow system?

A2:No. The fan air inlet is equipped with multi-layer drawer-type filters, and the heating elements are isolated from the airflow channels. Regular cleaning ensures safe and stable operation.

Q3: Which heating source is the most economical?

A3:If a natural gas supply is available, direct natural gas heating is recommended for lower operating costs. Electric heating is more suitable for small production capacities or applications with strict environmental requirements.

Q4: What material is used for the conveyor mesh belt?

A4:The equipment uses high-temperature-resistant, stretch-resistant Teflon mesh belts or specially designed stainless steel PTFE composite mesh chains to prevent material adhesion.

Q5: What are the installation and space requirements for the equipment?

A5:The installation site should provide an exhaust outlet for moisture removal, a level concrete floor, and sufficient space along the length direction for loading, unloading, and operation.
