Horizontal Indirectly Heated Dryer

Product Overview

The TONGZHENG horizontal indirectly heated dryer transfers heat to the material through a dedicated heating surface, keeping the product isolated from combustion gases and minimizing the risk of contamination. Optimized heat-transfer surfaces and continuous material agitation promote uniform drying with efficient heat utilization and lower energy consumption. Heating temperature and drying conditions can be adjusted to suit material properties, while the enclosed indirect-heating design limits dust generation and product loss. The robust horizontal construction supports stable continuous-duty operation and convenient access for inspection and maintenance.

Key Features

Indirect Heating Technology

Transfers heat to the material through a dedicated heating surface, keeping the product isolated from combustion gases and minimizing the risk of contamination.

Efficient Heat Utilization

Optimized heat-transfer surfaces and material movement improve thermal efficiency, helping achieve effective drying with lower energy consumption.

Uniform Drying

Continuous material agitation and controlled residence time promote thorough and even heat transfer, resulting in consistent final moisture content.

Controlled Drying Conditions

Heating temperature and drying conditions can be adjusted according to material properties, providing precise control over the drying process.

Reduced Dust and Product Loss

The enclosed indirect-heating design helps limit dust generation and material carryover, supporting cleaner and more efficient operation.

Wide Material Compatibility

Suitable for drying a variety of bulk and powder materials, particularly products requiring controlled heating or protection from direct flue-gas contact.

Reliable Continuous Operation

Robust horizontal construction supports stable continuous-duty operation while allowing convenient access for inspection and routine maintenance.

What Is a Horizontal Indirectly Heated Dryer?

A horizontal indirectly heated dryer is a rotary drying machine in which heat is transferred to the material through a dedicated heating surface rather than by direct contact with combustion gases. The material is fed into a rotating horizontal drum, where continuous agitation moves the material through the machine while heat is conducted from the heated shell or internal heating elements. Because the product is isolated from the heat source gases, the dryer is well suited to materials that require controlled heating or protection from contamination. The enclosed design also limits dust generation and product carryover, supporting cleaner and more efficient operation.

Applications

• Chemical powders and granules

• Mineral and ore powders

• Bulk materials requiring controlled heating

• Materials that must be protected from direct flue-gas contact

• Continuous drying of granular and powder products

• Industrial processes requiring consistent final moisture content
