Paddle dryer / Comparison of dryer 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.

Paddle dryer is a dryer which has heat medium such as steam injected into its shaft and blade called disc or paddle, and heats and dries fed materials with the heat transmitted from the shafts and blades.
As the shaft with the blades attached rotates, the material is agitated, heated, and dried as being moved forward to outlet.
The blades called discs or paddles are made based on the manufacturer’s unique technology and some manufacturer owns their self-cleaning technology which scrape off adhered materials with the blades as the shaft rotates. It prevents the dryer to be clogged with the material, and it also increases heat and drying efficiency by updating the surface where heat is transmitted.
This dryer is also called paddle dryer or disc dryer regarding the name of the blades.

The paddle dryer is very expensive compared with KENKI DRYER.
KENKI DRYER doesn’t inject steam into its blades, which are called paddles in paddle dryer. Therefore,  KENKI DRYER consume much less steam and the steam can leak when the paddles are worn out.
KENKI DRYER has better performance regarding self-cleaning function. KENKI DRYER also has models which injects steam into their blades. However, the models which does not inject steam into blades with our unique and patented international technologies can agitate, smash the materials more, and ends up with the better results in condition of the material after the drying.
Since the unique structure of KENKI DRYER scrapes off adhered materials forcibly as two blades facing each other rotate, surface of the blades never gets the fed materials adhered by being updated continuously and heat efficiency never drops.
Also, it has a feeding device for feeding dried materials while crushing and heating that no other companies have and a unique hot air heating and drying function and it heats air inside of dryer and hit the heated air on the fed material.
KENKI DRYER is a relatively inexpensive dryer which can manage any materials and can vaporize a very large amount of moisture.
KENKI DRYER is an eco-friendly decarbonizing dryer which is safe and does not generate CO2.

KENKI DRYER has already started AI･IoT development.
Rotation speed control with AI.
Remote control with IoT.

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.

Products

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.

Methods

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.

Self-cleaning screw

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.
