Direct vs Indirect Fired Heaters for Spray Dryers . Posted on 14th January 2019 in Dryers by John Real The question of direct or indirect fired spray dryers is one that is starting to be asked in the United States more and more often, especially in food production applications.
Indirect heat rotary dryers are most frequently used for products with small particle sizes that could result in excessive dust generation. They are also used for processes that require extreme control of the dryer exhaust. Indirect heat dryers depend on conduction and radiation to transfer the heat from the cylinder walls to the wet feed.
2019-10-31Indirect Heat Dryer. The indirect heat dryer or indirect heat transfer dryer, as a type of dryer, is widely applied to dry materials like slag, limestone, coal powder, slag and clay in the building material, metallurgy, chemistry and cement industry.
The Louisville Rotary Direct Heat Dryer provides a cost-effective, proven method of drying a variety of both organic and inorganic materials. Inlet gas temperature to the dryer can be optimized to suit the heat tolerance of the feedstock to provide maximum efficiency. The direct heat dryer utilizes hot gas as the primary transfer of thermal energy.

Knowing the difference between direct and indirect heat and when to use one, the other, or both is the difference between a grill rookie and a grill master. Direct heat will get you great grill marks over a fast flame, while indirect will bring your meat to temperature and make desserts on the grill a breeze.
Paddle Dryer are highly efficient, mechanically agitated, indirect heat transfer devices that add or remove heat from a process mass. Dual counter-rotating shafts with unique intermeshing wedge shape paddles produce intimate mixing and optimize heat transfer. The use of hollow paddles for heat transfer results in a compact machine.

Indirect dryers conductively heat a product through contact with a heated wall. Tray Dryer is used for the best drying results in conventional process. It is a double walled cabinet with Single or Two doors. The gap between two walls is filled with high density fibre glass wool insulation material to avoid heat transfer.
The rotary dryer design consists principally of a rotating cylinder that is enclosed in a furnace along its active length. With heat transfer indirect and through the cylinder wall, the gas velocities within an indirect dryer are low as compared to a direct heat dryer, and correspondingly, the off-gas system is smaller and more economical.
The directly heated rotary dryer operates on the principle of lifting and showering the product through a hot gas stream moving either in parallel or counter-flow whereas with the indirect dryer, which is more suited to fine and dusty materials, there is little or no contact between the product and the drying gases since they are heated from the outside, via a stationary jacket fitted with ...
Indirect processes rely on heat transfer media, such as hot oil, steam, or water, which is isolated from the treated material by a metal surface. In other words, the material itself never comes into direct contact with the heat transfer media.Through mechanical agitation,
