Advanced Patented Technology for No-Clogging, Low-Temperature, and High-Efficiency Drying

Dry the Undryable - Solve Sludge Problems Instantly

Companies often struggle with sticky, adhesive sludge that clogs conventional dryers and prevents smooth discharge.
KENKI DRYER, backed by 11 international patents, delivers completely clog-free, stable drying even for the most difficult wastewater sludge.

Patented Technology for Uniform, Full-Depth Drying

Flocculated sludge forms lumps that standard dryers cannot dry internally.
KENKI DRYER uses a unique crushing and size-reduction mechanism to break lumps, improve heat transfer, and ensure uniform drying from surface to core.

Low-Temperature Steam Drying for High-Value Upcycling

Using saturated steam at low temperatures, KENKI DRYER preserves material composition, making dried sludge ideal for compost, soil conditioners, fuel, and recycling.
A perfect system for turning waste into valuable resources.

Decarbonized, Cost-Efficient 24/7 Operation

With superior thermal efficiency, KENKI DRYER requires minimal steam and can achieve zero CO₂ emissions when combined with an electric boiler.
Blades rotate at under 5 rpm, reducing wear and maintenance. Continuous, simple operation enables unmanned 24-hour running.

Lower Waste Volume, Disposal Costs, and CO₂ Emissions

Drying significantly reduces sludge weight and volume, cutting industrial waste fees and truck usage—critical as disposal and transport costs rise.
Fewer trucks also mean lower carbon emissions.

Supports Japan’s Resource Recovery Strategy

Dried sludge can be used to recover phosphorus and other valuable minerals—resources Japan heavily depends on.
KENKI DRYER enables the stable low-temperature drying necessary for recycling and resource recovery.

Trusted by Industry Leaders

KENKI DRYER is recognized for its uniform drying, durability, low manpower needs, simple installation, and low operating costs.
For sticky sludge, slurry, beverage lees, organic waste, or recycling materials, KENKI DRYER is the most reliable solution available today.

Revolutionize Your Sludge Drying Operations: The KENKI DRYER Solution

The Sticky Sludge Crisis: Why Traditional Dryers Fail Your Wastewater Treatment Plant

Wastewater treatment plants discharge sticky, adhesive sludge that causes traditional dryers to fail. Flocculants used in wastewater treatment cause sludge to clump together during the drying process. When lumps form, heat cannot penetrate the material’s core, leaving the interior wet while only the surface dries. This inefficiency leads to clogging inside the dryer, production shutdowns, frequent maintenance, and ultimately, failed operations. The rising industrial waste disposal costs and trucking challenges of 2024 compound these problems, forcing companies to transport heavier, inadequately dried sludge at premium rates. Your facility needs a breakthrough solution.

KENKI DRYER: 11 Patents for Adhesive Sludge Drying Innovation

KENKI DRYER is a revolutionary indirect steam dryer engineered specifically for sticky and adhesive materials that defeat conventional technology. With 11 patents granted across 8 countries (Japan, Taiwan, USA, France, Germany, UK, Switzerland, Canada), KENKI DRYER represents truly innovative sludge dryer technology. Unlike batch dryers, KENKI DRYER operates as a continuous system with uniquely designed blades rotating at just 5 rpm. This design crushes and reduces material size within the dryer chamber, eliminating lumps and ensuring uniform heat distribution. The result is complete, thorough drying of even the stickiest sludge without internal clogging or material adhesion problems.

Three Critical Problems Solved by KENKI DRYER’s Continuous Drying System

The low-temperature steam process solves three critical challenges facing facility managers. First, it prevents clogging and material buildup by continuously processing and sizing down sticky materials, allowing seamless discharge without operational interruptions. Second, it achieves complete drying to reduce weight and volume significantly, cutting transportation costs and disposal fees compared to traditional wastewater sludge dryers. Third, it preserves sludge composition through low-temperature indirect steam heating, enabling valuable upcycling applications as compost, soil conditioner, or fuel. This transforms a disposal liability into a profit-generating asset suitable for mineral extraction and sludge recycling initiatives.

Environmental Leadership Through Zero-Emission Sludge Drying Technology

KENKI DRYER delivers exceptional environmental and financial benefits that align with corporate decarbonization goals. High heat efficiency minimizes fuel consumption, and with an electric boiler installation, produces zero CO2 emissions during the drying process—supporting your facility’s environmental commitments. Reduced truck transportation volume through effective sludge dehydration lowers carbon emissions and waste management costs further. The low 5 rpm blade rotation means minimal equipment wear, resulting in easy maintenance, remarkably low operating costs, and 24-hour unmanned continuous operation requiring fewer personnel.

Why KENKI DRYER Outperforms Competing Sludge Drying Solutions

    Companies installing KENKI DRYER report superior results: uniform drying quality, improved productivity, exceptional durability, and easy installation. Whether handling difficult wastewater treatment sludge, sticky slurry, beverage lees, or pursuing waste upcycling and organic waste recycling initiatives, KENKI DRYER delivers where standard industrial dryers fail.

    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.
