Direct-Fired Dryers Louisville Dryer Company
A direct fired dryer operates in one of two modes: co-current, or counter-current. In either of the above arrangements, the operation of a direct fired rotary dryer is based on the combustion system (burner) being directly coupled to the rotating shell.
Indirect rotary dryers IDRECO S.r.l.
Indirect rotary dryers differ from convective-direct dryers in that heat is transferred to the wet product by conduction and radiation through the cylinder wall or through a series of tubes located circumferentially to the cylinder. Indirect rotary dryers use as heating medium hot gases coming from a combustion chamber.
Rotary Dryer Design & Manufacturing Louisville Dryer

Louisville Dryer Company offers expertise in construction, service, and maintenance on many types of dryers, including Direct Heat Dryers, Direct Fired Dryers, Indirect Heat Dryers, and Steam Tube Dryers.. Our dryers are built using the latest technologies, in our own state-of-the-art factory, not at sub-contractor facilities.
Direct- VS. Indirect-Fired Rotary Kilns & Dryers: A
Although indirect-fired rotary kilns and dryers closely parallel the direct-fired rotary devices in operation, t he indirectly fired kiln or dryer is distinct from its direct-fired counterpart, due to the fact that all heat transferred to the processed material is conducted (and/or radiated) through the vessel shell wall.
Direct Fired Rotary Calciners, Heat Transfer Equipment
Direct Fired Rotary Calciners. In a direct fired dryer, heat transfer rate and process atmosphere composition/volume are dependent, therefore consideration must be given to the compatibility of the process material with the drying gas composition as well as the gas velocity.
Indirect Drying vs. Direct Drying FEECO International Inc.
When referring to rotary dryers, it’s usually safe to assume that a direct-fired rotary dryer is the topic of discussion. Direct dryers are used more frequently than their indirect counterparts, because of the efficiency they offer. And while direct fired rotary dryers are most often the selected drying method, indirect rotary dryers are a
How to Solve 3 Common Rotary Dryer Problems
How to Solve 3 Common Rotary Dryer Problems. Direct fired dryers have fuel and ignition per definition. Oxygen must be limited. The burner uses oxygen, so oxygen content is already lower than atmosphere. By employing a recycle loop, oxygen levels can be driven down even lower.
Rotary Dryers an overview ScienceDirect Topics
The dryer is typically sloped, so that the product enters and gradually falls toward the discharge end. In direct rotary dryers, the air is passed through burners, and directly comingles with the product. Rotary dryers have been used to dry seeds, stone gluten, distiller’s grains, and some fruit.

Rotary Direct Fired Dryers Built by Louisville Dryer
A rotary direct fired dryer built by Louisville Dryer Company provides a cost-effective and proven method to dry a variety of products. If your product is not affected by radiated heat from the burner flame or the products of combustion, then a direct fired unit will provide the maximum efficiency through the full utilization of all three heat transfer methods: radiant, convection, and conduction.

Rotary Drum Dryer Haarslev
The rotary drum dryer is a direct-fired hot air cascading type of dryer, which dries sludge to between 90 to 95 % dry solids. The material is gently dried as it cascades through the hot air flow. The hot air stream is provided by a direct-fired gas burner normally operating with natural- and bio-gas.
Drying Vulcan® Drying Systems
