Description of spray drying machine:

The rotary dryer is a type of agricultural dryer employed to reduce the liquid moisture content of the material it is

handling by bringing it into direct contact with a heated gas. Rotary dryer is widely used in food,building material,

metallurgy,chemicals,cements industry and be used for drying metallurgy,chemicals,industrial drying slag cement

limestone,coal,slag,clay and other materials.The aircraft is mainly composed of the rotary,jan plate,transmission,seal,

and other support equipment and component with a reasonable structure,well-produced,high yield,and low consumption,

the advantages of opertating convenience.Dryer capacity will depend on the properities,moisture content,drying temperature varies.

The spray drying machine operating principle:

The dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams.

The dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material

through the dryer under gravity. Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up

by a series of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back off the fins,

it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. This gas stream can either be

moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow).
