This Vortex is a high performance Incinerator proven by hundreds of business results as a Stir-Blowing Continuous Single Stage Incinerator. Consequently, the incinerator is broadly accepted and actively working in many of different business fields. It blows air needed for combustion from the lower part of Rotating Stir Arms, which are installed inside of the furnace, based on the same principle with the Hifukidake or an oral air blowing bamboo used in the kitchen of old days, and enables complete combustion while stirring the materials.
