Conveyor System Chain Belt Pre-Heating Uniform Tunnel Oven

Introduction

The tunnel dryer does not have multiple heaters in the upper and lower sections of the tunnel body. A windshield is fixed on the front side of each skip to separate adjacent carts. The hot air passes vertically through the material layer and is reversed multiple times. The temperature of the hot air can be controlled in stages.

There is another type of through-flow drying equipment in which two tunnels are juxtaposed, and several drying sections are arranged along the longitudinal direction of the whole tunnel. An axial fan is installed in the upper part of each drying section of the two columns of tunnels, so that the hot air passes through the two columns in the section. At the same time, a material layer of the tunnel is input with a certain amount of outside air, and a certain amount of exhaust gas is discharged to perform partial exhaust gas recirculation.

Features:

1. This machine is specially designed for drying the color stain or water based solvent.

2. Hot air can flatter the paint film, remove the air bubbles. With the IR heating, can fasten the thinner volatilize, and paint reaction. Shorten the drying time of the paint film, improve the working efficiency.

3. The wall of tunnel adopt double layer heat preservation materials, can keep the heat avoid being exhaust, and save the heating power

4. There is temperature controller for the IR tubes, can controll the heating start and stop, it make inner constant temperature be possible, and can be adjusted. Suitable to different drying purpose
