Summary

Micron Thermo Processor is an indirect heating type twin shafts disc dryer with jacketed trough casing. Twin shaft construction gives large heat exchange area and self cleaning effect showing the appearance in Fig. The series gives three types; M type, C type and F type. M type has 2 fan-shaped hollow heat transferring wings for high mixing ability. This type is applicable for poor flowability material, such as sludge and the advantage is high capacity drying for constant rate period. F type has dual torus discs with jacketed trough and the improved plug flow characteristics is expected. It is applicable for drying good flowability material for the drying period of the decreasing rate of drying. C type has the advantage of both M type and F type. It has high plug flow, less adhesion and wide application. It is useful for constant rate period to decreasing rate of drying. It can be applied to various applications from sludge to food and pharmaceutical.

MTD consists of a horizontal W shaped trough with heating jacket and dual rotor with multiple discs. Material is continuously agitated, heated and conveyed, then discharged via adjustable overflow weir. Heat medium, such as steam, hot water or thermal oil flows via rotary joint through the hollow rotating shaft and the heat transfer discs. Compact unit with large transfer area realizes effective drying. Dual shaft structure makes scraping effect to the material around the disc, to prevent the material from adhering on the discs. Control of moisture content is carried out by adjusting weir height or rotating speed of rotor. MTD F type and TorusDisc can apply oil as a heat medium.
