Vacuum and conduction drying series
HG series rotary drum dryers
HG series rotary drum dryer is a kind of inner heat conduction type of rotating continuous drying equipment. Rotatable drum through its lower chute, adhesion with a film thickness of the material, the heat through the pipeline to the drum wall, transmitted to the outer wall of the drum, and then transfer to the feed film ...
Detailed description
working principle:
Drum dryer is an internal heat conduction type of rotating continuous drying equipment. Rotatable drum through its lower chute, adhesion with a film thickness of the material, the heat through the pipeline to the drum wall, transmitted to the outer wall of the drum, and then transfer to the membrane material, so that the wet material film was evaporated off the wet, so moisture material points get dry. Dried material is in the blade means away from the roller surface of the roller blade, the blade is placed beneath the screw conveyor by a screw conveyor concentrated dry feed, packaging.
Features:
◎ high thermal efficiency. Due to a tumble dryer heat conduction heat transfer mechanism of the case, the direction of heat transfer is consistent throughout the operating cycle, in addition to cover the heat loss and heat radiation, the other for all the heat on the evaporator tube materials film of moisture, thermal efficiency up to 70% -80%.
◎ operating flexibility and wide applicability. Adjustable many factors drum dryer drying. Such as the concentration of the feed, the thickness of the coating material film, the heating medium temperature, drum rotation speed, can change the drying efficiency of the dryer drum, and no interaction of many factors involved. This brings great convenience to the drum drying operation, so that it can adapt to a variety of dried materials and different production requirements.
◎ drying time is short. Material drying cycle generally only 10-300 seconds, suitable for heat-sensitive materials. If the drum dryer provided in the vacuum vessel can be run under reduced pressure.
◎ drying rate. Since the cylinder wall coating put on thin film materials, typically 0.3-1.5mm, and heat and mass transfer in the same direction, the film surface can be expected to maintain strong evaporation 20-70kg.H2O / m2.h of.
Process Equipment Demo:
Installation:
The installation system is installed in accordance with the general layout, the ground should be smooth, steam pipes to be installed at the inlet pressure gauge and safety valve, each steam inlet flange connections are secure.
Adaptation Material:
◎ Apply to dry chemicals, dyes, pharmaceuticals, food, metallurgical and other industries liquid or more viscous materials.
maintain
◎ checked regularly rotating member rotation flexibility, whether there is jamming. Sprockets and other parts to regularly grease plus periodic calibration of pressure gauges and other measuring devices error. Wear and tear on the belt drive member has a serious phenomenon should be replaced.
◎ motor, reducer maintenance see motor maintenance manual gearbox.
Debugging:
◎ after commissioning the machine installation to conduct experiments
◎ inching master cylinder steering main motor observe correct.
◎ observe the main drum and all transfer member rotation is flexible, turned to observe whether the import and export steam, pressure gauge is within the operating pressure range.
◎ start the motor, the primary drum moving smooth operation, the material is added after the adjusted temperature the motor speed and the material on the roll film uniformity of the material to control the final moisture content.
◎ start auger motor, the output of finished drying material, auger motor speed adjustment based on the amount of finished drying.
