High-salt wastewater drum scraper dryer, bacterial paste material
dryer
Principle
Drum dryer is a kind of continuous drying equipment through steam
jacket-ed heating. The rotating cylinder body is attached to a
certain thickness of the liquid raw material film through the
material tank set in the lower part. The sensible heat (Steam) is
passed through the tubes to the inner and outer wall of the drum
bodies, and then is conducted to the liquid raw material film, so
that the moisture content of the raw material is rapidly evaporated
and the paste reaction occurs. With the continuous rotation of the
drum bodies, finally material is completely dried and the pasting
process accomplishes.
The completely dried products are scraped off the rotating cylinder
body by the scrapers installed in the surfaces of drums body, and
then gathered in the screw conveyor at the bottom of the scrapers.
At the discharge end of screw conveyor, a crushing device is set.
After being crushed and flake products is to
conveyed to the clean room for weighing and packing. At this point,
the drying and pasting process accomplishes.
Features
---high heat efficiency. Because the heat transfer mechanism of
rolling scraper dryer belongs to heat conduction, the heat transfer
direction is consistent throughout the operation cycle, except for
cover heat dissipation and heat radiation loss, the rest of the
heat is all used for the evaporation of simple material film wet
division, the thermal efficiency can reach 70%-80%.
---operation flexibility. Wide applicability. Many drying factors
of drum scraper dryer can be adjusted. For example, the
concentration of the feed, the thickness of the coating material
film, the temperature of the heating medium, the rotation speed of
the drum, etc., can change the drying efficiency of the roller
scraper dryer, and many factors are not related to each other. This
brings great convenience to the drying operation of the roller
scraper, so that it can adapt to the drying of a variety of
materials and different output requirements.
---Short drying time. Drying cycle of materials - generally only
10-300 seconds, suitable for heat sensitive materials. If the
roller dryer is set in a vacuum, it can be operated under reduced
pressure.
---the drying rate is large. Since the material film smeared on the
cylinder wall is very thin, generally 0.3-1.5mm, and the heat and
mass transfer directions are consistent, the evaporation intensity
of the material film surface can be maintained at 20-70kgH2O/m2h.
