DESCRIPTION
PLG series continuous plate 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 oc-
cupying 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 etc., and is well received by various industries.
Now there are three big categories, normal pressure, closed and vacuum
styles and four specifications of 1200, 1500, 2200 and 2500; and three kinds
of constructions A (carbon steel), B(stainless steel for contact parts) and C (on
the basis of B to add stainless steel for steam pipes, main shaft and support,
and stainless steel linings for cylinder body and top cover). With a drying area
of 4 to 180 m2, now we have hundreds of models of series products and vari-
ous kinds of auxiliary devices available to meet requirements of various prod-
ucts.
PRINCIPLE
Wet materials are fed continuously to the top drying layer
in the dryer. They will be turned and stirred continuously by
harrows when the harrow’s arm rotates, the material flows
through the surface of the drying plate along the exponen-
tial 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 dry-
ing 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 fil-
ter, return and mix mechanism for dried materials and suction
fan etc. solvent in those paste state and heat sensitive materi-
als can be easily recovered, and thermal decomposition and
reaction can be also carried out.
