Carbon Fiber Heating Tube in U-Shaped Tunnel Furnace Application

Introduction to Drying Rooms in Industrial Production

In industrial production, drying rooms are frequently used. The common types of drying rooms can be broadly categorized into two main types: fixed drying rooms and tunnel drying rooms. These can be further subdivided into fixed chamber-type drying rooms, mobile drying furnaces, drawer-type drying rooms, vertical drying rooms, horizontal drying rooms, and tunnel furnace drying lines. The commonly used electric heating tubes in these drying rooms include stainless steel heating tubes, uglerod tolali isitish quvurlari, and infraqizil isitish naychalari. Below is a brief introduction to the characteristics of various drying rooms and the industries in which they are commonly used.

Types of Drying Rooms

1. Mobile Drying Furnace

The mobile drying furnace is a type of traditional oil-fired drying box. It is large in size, equipped with wheels for mobility, and convenient to use. It is suitable for drying large equipment but has the drawback of causing significant pollution due to exhaust emissions.

2. Chamber-Type Drying Furnace

This type of drying furnace has a large volume and a simple structure. It is widely applicable and can dry various products such as plastic parts, hardware parts, and glass. However, it can only perform periodic production, has a long drying cycle, and the production frequency needs to be calculated. Typically, two to three drying rooms are needed for rotation. The heating methods used in these drying rooms include oil-fired, pellet fuel, carbon fiber heating tubes, or infrared heating tubes. The heating principle involves high-temperature air distributing heat throughout the drying room via thermal circulation.

3. Drawer-Type Drying Room

This type of drying room is suitable for drying small products and is ideal for periodic operations on production lines.

4. Vertical and Horizontal Continuous Drying Rooms

These two types of drying rooms can operate continuously, which increases the utilization rate of the drying room. They are suitable for heating and drying small to medium-sized products. The vertical drying furnace also has the advantage of occupying a small footprint. Typically, carbon fiber heating tubes or infrared heating tubes are used.
