Seafood processing factory sludge drying / Test cases


  • Material to be dry:Seafood processing factory sludge
  • Purpose of drying: To use as fertilizer after drying. Dried cell fertilizer. Cost reduction of industrial waste disposal. 
  • Moisture content: 80%W.B. before drying, 5%W.B. or less 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
  • Test result: OK

■ Self-cleaning screw / Steam Heated Twin Screw Technology
( SHTS technology )

One of the International Patented Technology that KENKI DRYER has is a self-cleaning structure called Steam Heated Twin Screw technology (SHTS technology). No matter how materials are sticky, adhesive and viscous is, they can be dried without clogging inside of the dryer because of this unique structure that no other products has.
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. Even raw material slurry which is strongly sticky and adhesive is fed with liquid state, the slurry can be dried surely without any trouble by using this technology. This SHTS technology took about 7 years to be completed and it is patented or applied for patents not only in domestics but also in abroad.
Also, in case of drying of organic sludge after dehydration process of water treatment, sludge often forms large lumps because they are affected by flocculant, and it often happens that only surface is dried but inside are not when sludge is discharged as large lumps. However, using by this technology, the materials being dried are forcibly sheared and torn off when they touch the pair of blades, or a blade and trough/cases. As the drying process is proceeded, the materials being dried becomes smaller and smaller since they are forcibly peeled off when they stuck to the blade, and also repeatedly shared, torn off and agitated during being carried and heated. As the size of the material being dried gets smaller, heat can be conducted and reached to inside the material thoroughly and quality of the material after drying becomes stable. Because of the low-temperature drying using saturated steam, there is no possibility that materials after drying are discharged with unstable quality caused by being carbonized, scorched or unevenly heated.

Patented in Japan, U.S.A, Taiwan, France, Germany, UK, Switzerland, Canada.

Sludge drying



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.
