The projection of described drag head within being parallel to the plane of rotating shaft is wide or larger with the projection of rake root afterbody in this plane.
There is water pipe in raking arm described raking arm inside, and there is water pipe in rotating shaft rotating shaft inside; In raking arm, in water pipe and rotating shaft, water pipe is interconnected, and in rotating shaft, water pipe is connected with outer pipeline, for input hot water or cold water.
In described body fuselage, can contain semi-canal type heating pipe line, in this pipeline, pass into steam or deep fat, material thermal source is provided.
Described raking arm is movably connected in rotating shaft, and raking arm can respectively wave 0-15 ° along the axial left and right of rotating shaft, is further convenient to stir upset material.
The wall surface material that the hothouse of described body fuselage inside contacts with material is preferably stainless steel or carbon steel, and corrosion resistance and heat resistance are good.
Beneficial effect: material of the present invention is in airtight hothouse, by the heating of hothouse external jacket, heat energy is led in material, simultaneously by being fixed on left and right in rotating shaft to the raking arm material that constantly overturns, make material surface and inner moisture gasification, by high-vacuum apparatus, extracted again out the steam of hothouse, reach the equipment of dry materials.This equipment can be widely used in the dry processing of pulpous state, paste, granular, powdery and fiberous material, is the desirable drying equipments of industry such as chemical industry, food, medicine, dyestuff.
