Among the various types of industrial dryers, the DH-170 Horizontal Belt Dryer Machine stands out as an efficient, versatile, and reliable drying equipment widely used in many industries including food processing, chemical manufacturing, biomass, and feed production.In this comprehensive review, we will cover everything you need to know about the DH-170 Horizontal Belt Dryer—from its technical specifications, working principle, applications, advantages, and how it compares with other dryers in the market. At the end, you will find the most frequently asked questions to help you make an informed purchasing decision.

What is the DH-170 Horizontal Belt Dryer Machine

The DH-170 Horizontal Belt Dryer is a type of continuous drying equipment that uses a perforated belt conveyor to transport materials horizontally through a drying chamber. Hot air is blown through the belt and material to remove moisture evenly and efficiently. This machine is designed to provide precise temperature control, uniform drying, and gentle material handling, which is critical for drying heat-sensitive or fragile products.The DH-170 is part of the DH series of horizontal belt dryers, known for their modular design, energy efficiency, and adaptability to various drying needs. The “170” in its name refers to its capacity and size class, making it suitable for medium to large-scale industrial drying applications.

Working Principle of the DH-170 Horizontal Belt Dryer Machine

The DH-170 operates on the principle of continuous drying with horizontal airflow:

1. Material Loading: Raw material is loaded evenly onto the perforated conveyor belt at the dryer’s feeding section.

2. Conveying: The belt moves the material steadily through drying zones arranged horizontally.

3. Airflow: Hot air is blown through the perforated belt from below or above, penetrating the material layer.

4. Moisture Removal: Moisture evaporates as the hot air passes through, carrying away the vapor.

5. Multi-zone Control: The dryer is divided into several independent zones, each with its own heating and ventilation control to optimize drying conditions for different material characteristics.

6. Discharge: Dried material exits at the end of the belt, ready for further processing or packaging.

The combination of adjustable belt speed, zoned airflow, and temperature control ensures that materials receive the right amount of drying time and heat, preventing under or over-drying and minimizing product damage.

Key Features and Advantages of the DH-170 Horizontal Belt Dryer Machine

 High Efficiency and Capacity

With an air volume capacity of 17 m³/min, the DH-170 can process large quantities of materials continuously. This feature is essential for industries with high throughput demands such as biomass pellet production or chemical granule drying.

 Modular Multi-Zone Drying Design

The machine’s multiple independently controlled drying zones enable precise regulation of temperature and airflow in each section of the belt. This modular approach helps to achieve:

• Uniform moisture removal across the material batch

• Customizable drying profiles for complex materials

• Energy savings by only heating required zones

Versatile Heat Source Compatibility

The DH-170 can use various heating sources including steam, hot water, thermal oil, and electricity. This flexibility allows users to integrate the dryer into existing factory utilities or use sustainable energy sources like biomass boilers or waste heat.

 Gentle Material Handling

The perforated belt design combined with adjustable belt speed allows for gentle treatment of fragile or heat-sensitive materials such as herbal medicines, vegetables, or chemical powders. The horizontal conveyor ensures minimal mechanical stress during drying.

Energy-Efficient Operation

The dryer supports air recirculation to reclaim exhaust heat and reduce energy consumption. Proper insulation and zoned heating contribute to maintaining thermal efficiency throughout operation.

Compact and Durable Build

With dimensions of 1300 × 550 × 2175 mm and a net weight of 600 kg, the DH-170 is designed for easy installation in limited factory spaces. The frame and belt are made from industrial-grade stainless steel or carbon steel to withstand corrosion and wear.
