Hot Air Dryer Introduction

The hot air dryer is researched and made on our own based on the international advanced technology. It is a modern industrial heat source updating and upgrading product which is preferred to be widely used in the electronic, food, pharmacy, printing, packaging and cleaning.Hot air dryer is typically used to dry high humidity materials like mud, gypsum, slurry, bentonite, vinasse, pomace, medicine dregs, bean dregs, sugar residue, soya residue, peat and rare earth as well as muddy, particle and flake organic and inorganic compound, chemical materials. The particle size of the materials dried by the hot air dryer is 2-5mm, and the materials are under low temperature which makes the dryer applied to heat sensitive materials.

Hot Air Dryer Features 

The hot air stirring dryer dry materials through the inner tube of the dryer to conduct heat indirectly, which prevents materials from touching hot air. This drying method is applied to dry some chemical materials, food and materials easy to be polluted. The inner tubes adopt stainless steels which make the cost 20-80% more than the ordinary one.

Hot Air Dryer Principle

The hot air stirring dryer adopts double shaft stirring and spiral pushing dryer processing high humidity materials. It can dry the original high humidity materials with 65% of water to the final ones with 5-12% of water inside. It only takes 2-20 minutes. As the dryer stirring blade stirs the wet materials intensely at high speed, materials meet the hot air completely. The moisture of the materials in the front part of the dryer is easier to be vaporized which makes the air temperature decrease rapidly. So, even the stirring dryer works with high-temperature air, materials are still at lower temperature.
