The Aerogel Felt Drying Tunnel Oven is an industrial tunnel-type hot air circulation drying equipment specially designed for continuous drying, curing, and aging treatment of aerogel insulation mats (felts).The equipment uses a continuous conveyor system to transport aerogel materials through a controlled heating chamber, where precise temperature, airflow, and processing time are applied to remove residual solvents, complete curing, or improve material stability.

Applications

Production of Ultra-Insulation Materials

Used for solvent replacement and removal of residual solvents before and after the supercritical drying process of aerogel felts.

Composite Material Curing

Used for continuous heating, shaping, and curing of aerogel felts reinforced with materials such as:

Glass fiber

Carbon fiber

High-Temperature Aging Treatment

Used to improve the hydrophobic performance, structural stability, and long-term durability of aerogel materials.

Standards

GB/T 34336

National standard for nano-aerogel insulation products.

GB 50058

Code for design of electrical installations in explosive hazardous environments.

(This standard is applicable because aerogel modification processes may involve flammable solvents such as ethanol.)

JB/T 10325

Technical requirements for industrial hot air circulation and tunnel drying ovens.

Features

Precise Temperature Control

Adopts multi-zone independent microcomputer PID temperature control, achieving high temperature uniformity with temperature deviation controlled within ±1°C.

Explosion-Proof Design

Equipped with safety protection systems including:

Explosion-proof motors

Explosion relief doors

Solvent concentration monitoring system (LEL)

to ensure safe operation in processes involving flammable solvent evaporation.

Optimized Airflow System

Uses a specially designed low-speed air circulation system to prevent aerogel surface powder from falling off or dispersing during drying.

High Efficiency and Energy Saving

Adopts high-density aluminum silicate fiber insulation layers combined with hot air circulation and heat recovery technology to reduce energy consumption and improve thermal efficiency.
