Detailed Product Description

PLG series continual dryer

Descriptions:

PLG series continual dryer is a kind of high efficiency conducting and
continuous drying equipment. Its unique structure and operating principle provide
advantages of high heat efficiency, low energy consumption, less occupying
area, simple configuration, easy operation and control as well as good operating
environment etc. It is widely used in drying process in the fields of chemical,
pharmaceuticals, agricultural chemicals, foodstuff, fodder, process of agricultural
and by-products,and is well received by various industries.
Principles:Wet materials are fed continuously to the top drying layer in the dryer.
They will be turned and stirred continuously by harrows when the harrows arm
rotates, the material flows through the surface of the drying plate along the exponential helical line. On the small drying plate the material will be moved to
its exterior edge and drop down to the exterior edge of the large drying plate underneath, and will then be moved inward and drop down from its central hole to
the small drying plate on the next layer. Both small and large drying plates are
arranged alternately so as materials can go through the whole dryer continuously.
The heating media, which could be saturated steam, hot water or thermal oil will
be led into hollow drying plates from one end to other end of the dryer. The
dried product will drop from the last layer of the drying plate to the bottom layer
of the smell body, and will be moved by harrows to the discharge port. The
moisture exhausts from materials and will be removed from the moist discharge port
on the top cover, or sucked out by the vacuum pump on the top cover for vacuum-type
plate dryer. The dried product discharged from the bottom layer can be packed
directly. The drying capability can be raised up if equipped with supplementary
devices such as finned heater, condenser for solvent recovery, bag dust filter,
return and mix mechanism for dried materials and suction fan etc. solvent in
those paste state and heat sensitive materials can be easily recovered, and thermal
decomposition and reaction can be also carried out.
