Self-cleaning mechanism KENKI DRYER / Sludge dryer, Slurry dryer, Waste dryer
KENKI DRYER which can dry sticky and adhesive materials that no other dryer can is an innovative drying apparatus having unique technologies with 2 patents in Japan, 9 patens in 7 abroad countries, 11 patents in total. Please consider about KENKI DRYER as dryer for organic waste with high moisture content, sludge dryer, slurry dryer, dryer for digestive fluid from the methane fermentation and waste recycling dryer.
It has 11 patents in 8 countries which are Japan, Taiwan, the Unites States, France, Germany, the United Kingdom, Swiss and Canada.
Since amount of saturated steam used as heat source of KENKI DRYER is small, there is no need for installing new boilers, and decarbonization and fuel cost reduction is possible by using redundant steam from the plants.
One of the KENKI DRYER’s technology which obtained an international patent is self-cleaning mechanism.
Because of this self-cleaning mechanism, any sticky and adhesive materials that no other dryers can handle is managed to be dried surely and evenly without clogging inside to the dryer by the unique mechanism.
In the self-cleaning mechanism, even if the material adheres to the blades in the dryer, other blades attached in opposite side forcibly peel the adhered material while they rotate, and the dryer is never clogged no matter how sticky and adhesive the material is.
Also, surface of the blades is always wiped up, so heating and drying ability never dropped. At the same time, the dried materials are smashed into small pieces and heat surely reaches to inside of the materials and dries them.
It is difficult to heat into inside of sludge containing flocculants since the sludge forms lumps while the drying process. Sludges are smashed to prevent from becoming lumps and heats are made to reach inside of the sludge.
Resident time of the materials in the dryer is controlled by changing rotating speed of main shaft, and moisture contents of dried material can be managed by adjusting the rotating speed of the shaft.
Steam used as heat source is not injected into the blades, so amount of steam consumption can be kept small.
Since the drying is processed in low temperature, there is no carbonization or burnt at the surface of the blades.
There is fairly small change in the component of materials after the drying and the dried materials can be used for various purpose such as raw material, fuel, feedstuff, etc.
Rotation speed of main shaft is very slow which is less 5RPM or lower, and there is little wear between the dry material and the blades. It can be used for quite a long time and does not need to be replaced.
Also, there is no leakage of steam from the blade since steam is not injected to them.

| ■ 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. 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.
| ■ Product characteristics |
KENKI DRYER has three main characteristics. They are 1) Any materials can be dried as expected including sticky, adhesive and viscous materials and raw material slurry that no other company can deal with, 2) dried material can by recycled or utilized as raw materials because of its low-temperature drying method, and 3) there is no need to assign operator since its continuous operating system makes 24 hours unattended operation possible.
| ■ Drying process |
The unique and original drying mechanism of KENKI DRYER is also International Patented Technology. Because 4 drying mechanisms which are crashing drying, agitation drying, circulation drying and indirect drying work simultaneously and add heat to material being dried repeatedly and continuously, inner part of the material is dried thoroughly and quality of discharged material after drying is stable. This series of drying mechanisms prevents agglomeration which causes insufficient drying from feeding process of the material into the dryer until discharging process after drying completed. Various ingenuities to conduct heat surely into inner part of the materials are exercised and stable heating and drying are proceeded continuously.
| ■ Heat source, Saturated steam |
Even KENKI DRYER uses only saturated steam as its heat source, it is outstanding in safety and hygiene point of view with its unique drying mechanism based on combined use of conductive heat transfer method and heated air method. Since steam is a stable heat source, quality of discharged material after drying is also stable and equable. Maximum allowed steam pressure is 0.7Mpa and adjustment of steam pressure, adjustment of drying temperature in other words, can be easily done. Saturated steam is commonly used in many factories so that it can be said as a familiar and handy heat source. In comparison with drying methods using burner or hot blasts, saturated steam method is an indirect drying applying heat exchange via pipes that steam is passing through, therefore, it hardly burns the materials and is outstanding in safety and hygiene point of view.
| 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. |
