Product
HG series (single drum double drum) drum roller scraper dryer
Detailed Description
Working principle
??
Roller squeegee dryer is an internal heating conduction type rotary continuous drying equipment . The
rotating drum passes through the lower chute and adheres to a film of
thickness. The heat is transported through the pipe to the inner wall of
the drum and is conducted to the outer wall of the drum. The feed film
is then conducted, so that the moisture in the film is evaporated and
dehumidified. The moisture content of the material is dry. The dried
material is placed on the surface of the drum scraper shovel away from
the drum to the screw conveyor placed under the scraper, the dry
material is concentrated and packaged by the screw conveyor.
Performance characteristics
◎ high thermal efficiency. Because the heat transfer mechanism of the
roller scraper dryer is heat conduction, the heat transfer direction is
consistent throughout the entire operating cycle. Except for the cover
heat dissipation and heat radiation loss, all the remaining heat is used
for evaporation of the moisture content of the cartridge film, and the
thermal efficiency can be achieved. 70%-80%.
◎ Operational flexibility, wide applicability. Adjust the drying
factors of the drum dryer. Such as 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 all change the drying
efficiency of the roller squeegee dryer, and many factors are not
implicated in each other. This brings great convenience to the drying
operation of the roller squeegee , so that it can adapt to the drying of
various materials and the requirements of different production.
◎ Short drying time. The drying cycle of materials is generally only
10-300 seconds, suitable for heat-sensitive materials. If the
roller scraper dryer is set in a vacuum, it can be operated under
reduced pressure.
◎ high drying rate. Because the coating material applied to the wall
of the coating is very thin, generally 0.3-1.5mm, and the direction of
heat transfer and mass transfer is consistent, the surface of the
coating film can maintain the evaporation intensity of 20-70kg.H2O/m2.h.
Installation
The installation of the machine is based on the
layout of the general layout, the ground should be flat, the steam pipe
inlet pressure gauge and safety valve should be installed, the steam
inlet flange connected firmly.
Adaptable materials
◎ suitable for chemical, dye, pharmaceutical, food, metallurgy and other industries liquid or more viscous material drying.
Maintenance
◎ Periodically check the rotational flexibility of the rotating parts
to see if they are stuck. Periodically add grease to parts such as
sprocket and periodically correct errors in metering devices such as
pressure gauges. Serious wear on the V-belt transmission should be
replaced in time.
◎ For the maintenance of the motor and reducer, refer to the instructions for use and maintenance of the motor and reducer.
Commissioning After
the installation of this machine, a trial run test shall be performed first
.
◎ Observe whether the main roller and the transmission parts are
flexible. Observe whether the steam inlet and outlet are connected and
whether the pressure gauge is within the working pressure range.
◎ Start the motor, the main roller is running smoothly, and after the
temperature rises, add the material and adjust the rotation speed of the
motor and the uniformity of the film on the roller to control the final
moisture content of the material.
◎ Start auger motor, output dry finished material, and adjust the speed of auger motor according to the amount of dry product.
