Foodstuff / Agriculture Industry Harrow Type Vacuum Rake Dryer Equipment
Product Description:
The dryer is a machine used to heat treat powders, granulates, filter cakes and pasty products in a full-continuous process.
These processes vary from drying, cooling, crystallizing and calcimining to melting, evaporating, solvents, sterilizing, etc
The paddle dryer has a heated through containing rotating heated paddle shafts. The product is fed into the front of the machine. The through is oriented at a small angle of inclination, placed slightly in unloading position. The product moves to the outlet as a result of gravity. The paddles do not have a transport function.
They are designed for maximum heat transfer. At the outlet side, the product moves out of the machine via the overflow unit.
Introduce:
Hollow blade type dryer is a predominantly conduction horizontal mixing type dryer, Hollow blade built-in equipment.
Pour hot air or heat conduction oil into the hollow blade, make through mixing material contact with hollow blade fully, has reached the effect of drying materials.

Applications
Vacuum rake dryer device uses steam jacket to indirectly heat materials, and exhaust under high vacuum, so it is especially suitable for materials that are not resistant to high temperature, easy to be oxidized at high temperature, or materials that are easy to produce powder when drying (such as various fuels), as well as the drying process of steam or solvent must be recycled materials drying operation.In the vacuum rake dryer, the moisture content or solvent content of the dried material is up to 90%, while the lowest is only 15%.The dried material is slurry, paste, granular, powder, can also be fibrous.The moisture content of these materials after drying generally reaches 0.1% or even 0.05%.
Working:
The dried material is added from the middle of the shell. Under the stirring of the rotating rake teeth, the surface of the
material is constantly updated when it contacts with the shell wall. The dried material is indirectly heated by steam, and the moisture of the material is gasified. The gasified moisture is pumped away by the vacuum pump in time. The machine can use the sandwich and rake teeth heating method at the same time, with larger heat transfer area and high thermal efficiency was obtained. Due to the high operating vacuum, the water vapor pressure on the surface of the dried material is much higher than that in the evaporation space of the drying shell, which is conducive to the discharge of the internal and surface water of the dried material, and the movement of the water molecules of the dried material, so as to achieve the purpose of drying.
