WORKING PRINCIPLE

HG Series Cylinder Scratch Board Dryer is a kind of rotating continuous drying equipment with internal heating conducting function. The material film will stick to the bottom of the rotating cylinder. The heat is transferred to the internal wall of the cylinder through piping system and it will be conducted to the external wall and material film. The moisture of the wet material film will be easily evaporated and the dried material will be scraped from the cylinder surface and transfer to the packing area by the screw conveyor.



APPLICATION

This dryer is suitable for drying liquid raw material or sticky material in chemical industry, dyestuff industry, pharmaceutical industry, foodstuff industry, and metallurgy industry, and etc.



FEATURES

High heat efficiency: The heat transfer of the cylinder dryer is heat conduction and the conducting direction keeps identical with operation circle. Most of the heats can be used for evaporation of wet materials on the wall the cylinder. The efficiency can reach 70-80%.

Flexible operation elasticity and wide application: Various drying factors of the dryer can be adjusted, such as concentration of the liquid, thickness of material film, temperature of heating medium, rotating speed of the drum, and etc. These factors can change drying efficiency of the cylinder dryer. As these factors have no interrelations each other, it brings great convenience to dry operation and makes it applicable to dry different materials and meet different production requirements.

Short drying period: The drying period of materials is normally 10 to 300 seconds, so it is suitable for heat-sensitive materials. It also can be pressure reducing operated if it is put in vacuum vessel.

Fast drying rate: The thickness of the material film on the wall of the cylinder is very thin. Normal, thickness is 0.3 to 1.5mm. The directions of heat and mass transmittal are identical so the evaporation strength on the surface of material film can be 20-70 kg.H2O/m2.h.

Notes:

We can design double cylinder dryer with feeder on the top based on customer's requirements.



Installation:

This dryer has to be installed in accordance with the general layout. The ground should be smooth, and the steam inlet should be installed with pressure gauge and safety valve. Make sure all flanges are securely connected.



Commissioning:

- Observe and make sure the main cylinder is rotating correctly.

- Observe and make sure the rotation of the cylinder and various transmission components is flexible.

- Observe and make sure the steam inlet and outlet are connected and the pressure gauge is within the operating range.

- The operation of the main cylinder shall be stable after motor started. The material shall be fed into the dryer after temperature rises and then adjust the motor speed in order to control the uniformity of the film and the final moisture content of the material.

- The finished product shall be discharged when starting the auger motor. The auger motor speed shall be adjusted according to the conveying capacity of the finished product



Maintenance:

- Schedule regularly checks for the rotation flexibility of rotating parts and check if there is any jamming.

- The sprockets and other components shall be regularly greased.

- Schedule periodic calibration for pressure gauges and other measuring devices.

- The V-belt transmission is a wear part and it should be replaced regularly.

- The maintenance of motor and reducer should refer to its own manual.
