Four drying mechanisms KENKI DRYER / Sludge dryer, Slurry dryer, Heat pump sludge 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.
The theme of this video is drying mechanism of KENKI DRYER.
The mechanism to dry sticky and adhesive materials that no other dryer can has 11 patents in 8 countries includes Japan.
There are four drying mechanisms in KENKI DRYER.
Outside of dryer’s trough, heat is added by steam from the side and the bottom.
This is a feeding device which has two shafts with special blade rotating continuously. This device crashes solid materials and moves adhesive materials forward smoothly.
Steam is inserted into the shafts, so the shafts and the blades continuously heat and dry the materials.
Two shafts with blades which has international patents are attached to dryer’s body, and heat and dry the materials being dried while they are rotating. They peel, chop, and agitate the materials at the same time.
Steam is inserted into the shafts, so the shafts and the blades heat and dry the materials continuously.
The materials adhered to the blade are peeled off by blades in the other side and surface of the blade is always wiped up, therefore, heating and drying performance don’t drop.
By changing rotation speed, the material’s residence time in the dryer can be changed and moisture contents can be controlled.
Air in the dryer is sucked by circulating blower and is heated by passing through a steam heat exchanger attached upper side of the dryer, then returned to the dryer.
Hot air always hits from upper side of the material, and this improve the drying efficiency.
Since no air is mixed from outside and air inside of the dryer is circulated and heated, temperature in the dryer is not affected by outside temperature and kept constant.
The structure which can dry sticky and adhesive materials that no other dryer can, which can heat and dry from all direction, and which has combined use of indirect heating and hot air blowing has 11 domestic and international patents among 8 countries.
An innovative dryer with extremely high thermal efficiency.
| ■ 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.
| ■ 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.
| ■ 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.

| ■ 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.

| 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. |
