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.
