Choose KENKI DRYER for drying sticking adhesive qualities.
Even if the drying object has a strong sticking adhesive quality and is difficult to dry, KENKI DRYER can easily and smoothly dry it. For example, dehydrated sludge discharged from wastewater treatment plants with a strong sticking adhesive quality is difficult to dry. Depending on the type of dryer, sludge can become clogged inside the dryer during the drying process and may not be able to be discharged. With KENKI DRYER, however, even sticky or adhesive materials that would normally cause clogging can be dried easily without clogging inside the dryer. KENKI DRYER is an innovative drying device with unique technology that has been granted a total of 11 patents, including 2 in Japan and 9 in 7 countries overseas.
After dehydration, many of the dried sludge objects are found to be in a lumpy form, regardless of whether they are inorganic or organic. In KENKI DRYER, the dried objects, such as lumpy sludge, are crushed to a certain extent inside the dryer, and by reducing the surface area, the drying process is able to thoroughly dry even the inside of the dried objects. Even with lumpy objects to be dried, there are cases where the sticking adhesive quality is so strong that they get stuck inside the dryer and cannot be discharged, but KENKI DRYER has a unique mechanism that is patented worldwide, so it can dry objects smoothly without getting stuck inside the machine.
In addition, the sludge discharged from wastewater treatment plants tends to clump together during the drying process due to the effect of the flocculants used during wastewater treatment. When the material being dried forms lumps, the heat does not spread sufficiently throughout the material and the inside of the material does not heat up, so only the surface dries and the inside does not heat up and dry. Even if the material being dried forms lumps, KENKI DRYER can dry the inside of the material sufficiently by crushing and reducing the size of the material to a certain extent inside the dryer and reducing the surface area.
By drying sludge discharged from wastewater treatment plants at low temperatures, it is possible to utilize it as compost, soil conditioner, fuel, etc. as upcycling, with minimal changes in composition after drying. KENKI DRYER is an indirect drying system that uses steam as a heat source at low temperatures, so after drying, there are minimal changes in the composition of the dried material, making it fully recyclable and suitable for upcycling.
KENKI DRYER, with 11 patents in 8 countries, is an indirect steam dryer, but it is a completely unique product, different in structure from other similar indirect steam dryers. The KENKI DEYER uses steam as a heat source, but its high drying heat efficiency means that less steam is used. The use of excess steam is not costly in terms of fuel costs, and the dryer does not emit carbon dioxide during the drying process, allowing for decarbonized drying. Alternatively, by installing an electric boiler, no greenhouse gases or CO2 emissions are produced during drying.
The dryer’s blades rotate at a very slow speed of 5 rpm or less, which means that wear on parts is minimal and maintenance is easy and inexpensive. KENKI DRYER is a continuous dryer, not a batch dryer that stores materials to be dried. Therefore, operation is simple and unmanned operation is possible 24 hours a day.
Drying sludge to reduce the weight and volume of waste products can contribute to environmental protection and decarbonization by reducing the cost of industrial waste, which is rising due to the recent trucking problem in 2024, and by reducing the number of trucks used to transport waste, thereby reducing carbon dioxide emissions.
Japan is almost 100% dependent on imports for its mineral resources. In particular, precious and rare metals are important resources that must be secured in order to maintain and strengthen international competitiveness. One measure for securing mineral resources is to reuse and recycle the minerals contained in sewage sludge, which is important for environmental protection and leads to a reduction in greenhouse gases. Phosphorus, which is currently imported and is also essential, is another mineral that we cannot do without. For this reason, the extraction of phosphorus from sewage sludge is being promoted as a national project.
The upcycling and recycling of sludge, which is always discharged from wastewater treatment plants, is emphasized for environmental protection, decarbonization and securing resources that are dependent on imports and the demand for which is only increasing.

Inorganic sludge drying / Brochure
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.
