Food factory sludge drying / Test cases / Sludge drying, Reduction of industrial waste costs

Food factory sludge drying / Test cases


  • Material to be dry: Food factory sludge
  • Purpose of drying: To use as fertilizer after drying. Dried cell fertilizer. Cost reduction of industrial waste disposal. 
  • Moisture content: 85.3%W.B. before drying, 19.6%W.B. after drying
  • Requirements for dryer: No clogging inside of the dryer since materials being dried are sticky. 24-hour unattended operation. No change in components of the dried materials after drying because of the purpose for Fertilizer

■ Sludge drying/ Drying of sticky and adhesive materials that no other company can deal with. International Patented Technology


No matter how sticky, adhesive and viscous the material is, KENKI DRYER of International Patent can dry it without clogging inside of dryer and with stable operation that no operational trouble occurs because of its unique mechanism. For example, even materials stuck to the blades of one screw, blades of the other screw in the dryer’s body forcibly peels the materials off as they rotate. Since the blades rotate by peeling the material off each other, any sticky, adhesive and viscous material does not adhere to the blade, and the blades continue rotating, peeling, agitating and heating material without stopping while they carries material further. Also, since surface of blades are always renewed and kept clean, heat near the blades is not blocked and it is conducted directly into the materials.

Please consider KENKI DRYER for drying of sticky materials, adhesive materials and materials in liquid state that no other dryer can deal with.
Initial, running and maintenance costs are low because of its simple structure based on internationally patented technology.
For sludge drying, costs of our dryers are estimated to be retrieved within 2, 3 years by reducing industrial waste disposal cost.
For raw material slurry drying, laborious works of manual operation will be decreased significantly by replacing box shaped compartment tray dryer with our dryer
In case of organic wastes drying, the waste can be recycled as fuel, fertilizer, soil conditioner and feedstuff after being dried.
