Direct heat dryers where the heat transfer occurs by convection of hot air or gas inside a rotary cylinder are the most common and used thermal dryers Hot air or gas flows through the cylinder and then transfers to the product warming it and evaporating the water therefore temperature of heating media inside the dryer is the mean parameter. If you are interested in our company's products, we welcome your consultation 7/24 hours, and we are committed to creating the most suitable solution for you.
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.
Rotary dryers also come in two variations Direct rotary dryers Lift and douse the product with hot air through a parallel or counter flow hot gas stream Indirect rotary dryers Heat the product from the outside resulting in minimal contact between the product and the actual drying gasses This method is more suitable for dusty or very.
