Working Principle:Wet materials are continuously fed into the first layer drying
plate on the top of the dryer. They will be turned and stirred by
the rakes whose arms make rotational motion. The materials flow
through the surface of the drying plate along the index spiral
line. On the small plate the materials will move to the outer edge
and drop down to the large drying plate. On the big one they will
move inward and drop to the small plate on the next layer from the
central hole. Both small and large drying plates are arranged
alternately so that the materials can get through the whole
continuous plate dryer. The heating media will be led into the
hollow drying plate. The heating media includes saturated steam,
hot water and conduction oil, and it will enter from one end and
derive from the other end. The dried materials will drop from the
last layer of the drying plate to the bottom layer of the shell.
Finally, they will be transferred to the discharge port by the
rakes. The moisture escapes from materials and will be expelled
from the wet discharge port on the top cover. The moisture of
vacuum type drying machine will be drawn out by the vacuum pump.
Drying pasty and heat sensitive materials, this continuous plate
dryer can recover the solvent and conduct pyrolysis and reaction
operation.
Application:
PLG continuous plate dryer is appropriate for drying, calcining,
pyrolysis, cooling, reaction and sublimation in the chemical,
pharmaceutical, pesticide, food and agricultural industries. This
drying machine is mainly used in the following fields:
1. Organic chemical products: resin, melamine, aniline, stearate,
calcium formate and other organic chemical material and
intermediate
2. Inorganic chemical products: calcium carbonate, magnesium
carbonate, white carbon black, sodium chloride, cryolite, various
sulfate and hydroxide
3. Medicine and food: cephalosporin, vitamin, medicinal salt,
aluminium hydroxide, tea, ginkgo leaf and starch
4. Fodder and fertilizer: biological potash fertilizer, protein
feed, grain, seed, herbicide and cellulose
