Description

     HG Drum Pharmaceutical Conductive style drying machine (Drum dryer) (drum drying Equipment) is a kind of rotating continuous drying equipment with internal heating conducting-style. Certain thickness of materials film attach to the drum from material liquid vessel under the drum. Heat is transferred to the internal wall of the cylinder through pipes and then to the external wall and to materials film, to evaporate the moisture in materials film so as to dry materials. Dried products are then scraped off by the blade fitted on the surface of the cylinder, fall down to the spiral conveyor under the blade, and are conveyed, collected and packed.  

Performance characteristics
◎High thermal efficiency. The principle of heat transfer of rotary drier is heat conduction which heat conducting direction keeps identical with operation cycle. Except cap heat dissipation and radiation loss, all heat energy can be used for evaporating wet materials on the wall of roller. Thermal efficiency could reach 80%-90%.
◎Large operation elasticity and wide application. Various drying factors of the rotary drier can be adjusted, such as density of feeding materials, thickness of materials film, temperature of heating medium, rotating speed of roller etc, which can change drying speed. As these factors have no interrelations with each other, it brings great convenient to dry operation, and makes it applicable to suit various materials and to meet different requirement of production.
◎Short drying period. The drying period of material is normally 10 to 15 seconds, so it is suitable for heat-sensitive material. It can be also working under less pressure condition if it is put in vacuum device.
◎Drying rate is quick. As material film coated on the wall of roller is very thin. Normally thickness is 0.3-1.5 mm, plus heat and mass transfer direction are identical, the evaporation capacity on the surface of film can keep at 15-70kg.H2O/m2.h.
Applications
◎  It is suitable for drying liquid raw material or sticky material in chemical industry, dyestuff industry, pharmaceutical industry, foodstuff industry, and metallurgy industry and so on.
Maintainence
◎Regularly check the rotation flexibility of rotating parts, whether there is the phenomenon of clamping. Sprocket and other components should be regularly added grease, and regularly correct the pressure meter and other metering device errors. The V-belt drive parts has serious abrasion phenomenon should be replaced.
◎Motor, reducer maintenance details see motor, reducer, use and maintenance instructions.
Debugging
After the installation of the machine, the test run should be carried out first.
◎Move the main motor and observe the correct steering of the main roller.
◎Observe whether the rotation of the main drum and each component is flexible, observe whether the steam inlet and outlet are connected and whether the pressure gauge is in the working pressure range.
◎Start the motor, the main drum running smoothly, after rising temperature, add material, adjust the speed of the motor and material on the roller film uniformity to control the final moisture content of the material.
◎Start the winch motor, output the dry finished material, adjust the speed of the auger motor according to the amount of dry finished products.
