Kenki : sludge dryer

Sludge after dehydration process of wastewater treatment is often affected by flocculants and forms large lumps, and it frequently happens that only surface is dried but inside are not when sludge is discharged as large lumps.

In the drying process of Kenki, the materials are moved forward into the dryer’s main body smoothly by being heated and crashed with a feeder at the inlet. The materials get smaller and smaller since they are continuously sheared and agitated during conveying and heating. As the material gets more divided, heat reaches inside more smoothly and surely, and quality of outputs becomes stable.

Kenki has a very simple construction and its initial cost is estimated to be repaid with the cost of industrial waste disposal for about 2 -3 years. Also, as the heat source of drying is only saturated steam, a mechanism based on combined use of conductive heat transfer method and heated air method helps to achieve a high quality of safety and hygiene, and running cost can be kept low by using surplus steam within your facility. Machine operation is conducted in continuous mode easily and there is no need for supplementary operators and labor. Since the quantity of replacement parts is small, maintenance is easy and its costs are reduced.
