Introduction of Tunnel Drying Oven

1. Composition

The tunnel drying oven mainly consists of conveying system, hot air drying system, automatic temperature control heating system, circulating fan air equalizing system, dehumidifying system and electrical control system.

Description

It adopts relay-controlled fully automatic design. Except manual loading & unloading, all process steps are completed automatically. Operators place workpieces on the conveyor belt; the conveying system automatically feeds workpieces into each process section in sequence. After drying and cooling, products reach the unloading station to finish the whole drying process. Rational design, nice appearance, small footprint, easy disassembly and maintenance.

2. Conveying System

Composed of cycloidal pin gear reducer, conveyor belt, main drive shaft and driven shaft. Conveyor options: stainless steel mesh belt, Teflon mesh belt, PVC belt, rollers, etc. (Material selected per customer’s demand). Speed: 0～6 m/min, continuously stepless adjustable.

3. Hot Air Drying System

Includes circulating fan, electric heating tube, temperature sensor and temperature controller. The fan keeps hot air evenly distributed inside the oven to avoid uneven heating. Hot air (adjustable from ambient temperature to 250℃) blows uniformly on workpieces to speed up drying.

4. Dehumidifying System

Moisture exhaust fan extracts vapor inside the oven and discharges it outdoors via external pipes.

5. Electrical Control System

Semi-automatic relay control. Low-voltage components are high-quality domestic famous brands. Emergency stop buttons at inlet and outlet for safety. Two-color indicator lights on control cabinet show running / fault status.

Application

Widely used in hardware, packaging, electronics, leather, coating, plastic, food and other industries. Fast temperature rise, uniform heating, continuous baking inline with workshop production. Baking temperature, conveyor speed and time adjustable to greatly improve productivity and operation convenience.

Basic Parameters, Structure & Features

Tunnel oven, also called drying line, is tunnel equipment for product drying via heat conduction, convection and radiation. It mainly uses far infrared for heating. The interior is made of ceramic and stainless steel to ensure infrared covers every corner for uniform heating and energy transfer.
