KENKI DRYER: The Ultimate Drying Solution
Why KENKI DRYER is Chosen for Organic Sludge Dryers
KENKI DRYER is highly effective for drying sticky, high-moisture organic sludge from wastewater treatment plants. Its patented non-clogging technology allows smooth and continuous drying even when the sludge is adhesive or clumpy. It crushes lumps inside the dryer, improving heat transfer and ensuring the entire mass is dried thoroughly. Low-temperature drying preserves the sludge’s composition, enabling its reuse as compost, soil conditioner, fuel, or raw material for biochar and bio-coke. This supports environmental sustainability, cost reduction, and decarbonization.
Why Choose KENKI DRYER?
KENKI DRYER is a world-patented drying solution that efficiently dries sticky, high-moisture materials without clogging. Using low-temperature steam heating, it preserves the original properties of materials while ensuring smooth and uniform drying.

Low temperature drying of difficult to dry organic sludge for upcycling with KENKI DRYER
Even if the object to be dried has a strongly sticking adhesive quality and is difficult to dry, the KENKI DRYER can easily and smoothly dry it. For example, dewatered sludge discharged from wastewater treatment plants with strong adhesive stickiness is difficult to dry.
Depending on the type of dryer, sludge may become clogged inside the dryer during the drying process and not be discharged.
The KENKI DRYER uses a unique mechanism that is patented worldwide to enable the smooth drying of even dewatered sludge with strong adhesive stickiness and high water content without clogging inside the dryer.
After dehydration, many of the dried sludge objects, whether organic or inorganic, are found in a lumpy form. With KENKI DRYER, the dried objects such as lumpy sludge are crushed to some extent inside the dryer, and by reducing the surface area, drying can be carried out thoroughly even inside the dried objects. Even with clumpy dried objects, there are cases where the adhesive quality is strong during drying and clogging occurs inside the dryer, and the dried objects cannot be discharged, but with KENKI DRYER, the unique mechanism of the world patent prevents clogging inside the dryer, and the dried objects can be dried smoothly.
In addition, sludge discharged from wastewater treatment plants tends to clump during the drying process due to the effect of flocculants used in wastewater treatment. When the material to be dried forms lumps, the heat is not sufficiently distributed to the inside of the dried material, so only the surface dries and the inside does not heat up and dry. Even if the material to be dried forms lumps, the KENKI DRYER can dry the inside of the dried 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 the sludge discharged from wastewater treatment plants at low temperatures, the components of the sludge change little after drying, making it possible to use it as a compost, soil conditioner, fuel, etc. as an upcycled product. KENKI DRYER uses steam as a heat source for indirect drying at low temperatures, so the components of the dried material change little after drying, making it possible to use it as an upcycled or recycled product.
Also, by reducing the weight of the sludge through drying, the amount of industrial waste produced can be reduced, which in turn helps to reduce the cost of industrial waste, which has increased in recent years due to the 2024 trucking issue and other factors, and also helps to reduce carbon dioxide emissions by reducing the number of trucks used, thereby contributing to environmental protection and decarbonization.
KENKI DRYER, which has 11 patents in 8 countries, is a steam indirect dryer, but it is a completely unique product with a different structure from other steam indirect dryers. Direct-fire dryers, such as those that use burners, emit carbon dioxide, which is bad for the environment and goes against the trend of decarbonization. Because they dry at high temperatures, they use a lot of fuel and their parts wear out quickly, making them expensive to maintain.
KENKI DRYER uses steam as a heat source, but because of its high drying heat efficiency, it only needs a small amount of steam, so you can use the steam you’re currently using, and if you use excess or surplus steam, you don’t have to pay for fuel. The dryer doesn’t emit carbon dioxide when it dries, so you can dry without carbon dioxide. Alternatively, by installing an electric or hydrogen fuel boiler, there is no emission of global warming gases or carbon dioxide CO2 during the drying process.
In addition, there are no problems after start-up, and the rotation speed of the dryer’s main body blades is very slow at less than 5 rpm, so there is little wear and tear on parts, and maintenance is easy and inexpensive. KENKI DRYER is a continuous drying system, in which the drying material to be dried is stored, rather than a batch system. Therefore, operation is simple and unmanned operation is possible 24 hours a day.
Japan is almost 100% dependent on imports for its mineral resources. In the future, precious metals and rare metals in particular will continue to be important resources, and securing these resources is essential to maintaining and strengthening international competitiveness. One of the measures to secure mineral resources is the reuse and recycling of minerals contained in sludge, which will contribute to environmental protection and reduce greenhouse gas emissions. Phosphorus, which is currently imported from China, is also an indispensable mineral. Therefore, the extraction of phosphorus from sewage sludge is being promoted as a national project. The recycling of sludge, which is a necessary part of wastewater treatment plants, is important for environmental protection, decarbonization, and securing resources that are currently dependent on imports and demand is only increasing.
Wood is currently in short supply in Japan. The use of dried organic sludge as a fuel instead of wood or the use of dried organic sludge as biochar or bio-coke by carbonization is attracting much attention. For example, bio-coke can be used as a reductant or deoxidizer to replace coke in the steel and foundry industries. Biochar and bio-coke are carbonized materials made from biological resources that are effective in revitalizing organisms and improving the environment. For carbonization, please contact us about Biogreen, our pyrolysis equipment that does not use fossil fuels and does not emit CO2, a greenhouse gas.
