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.

Competitive comparison

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

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

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.

A fuel is any material that can be made to react with other substances so that it releases energy as thermal energy or to be used for work. The concept was originally applied solely to those materials capable of releasing chemical energy but has since also been applied to other sources of heat energy, such as nuclear energy (via nuclear fission and nuclear fusion).
The heat energy released by reactions of fuels can be converted into mechanical energy via a heat engine. Other times, the heat itself is valued for warmth, cooking, or industrial processes, as well as the illumination that accompanies combustion. Fuels are also used in the cells of organisms in a process known as cellular respiration, where organic molecules are oxidized to release usable energy. Hydrocarbons and related organic molecules are by far the most common source of fuel used by humans, but other substances, including radioactive metals, are also utilized.
Fuels are contrasted with other substances or devices storing potential energy, such as those that directly release electrical energy (such as batteries and capacitors) or mechanical energy (such as flywheels, springs, compressed air, or water in a reservoir).

Compost is a mixture of ingredients used as plant fertilizer and to improve soil’s physical, chemical, and biological properties. It is commonly prepared by decomposing plant and food waste, recycling organic materials, and manure. The resulting mixture is rich in plant nutrients and beneficial organisms, such as bacteria, protozoa, nematodes, and fungi. Compost improves soil fertility in gardens, landscaping, horticulture, urban agriculture, and organic farming, reducing dependency on commercial chemical fertilizers. The benefits of compost include providing nutrients to crops as fertilizer, acting as a soil conditioner, increasing the humus or humic acid contents of the soil, and introducing beneficial microbes that help to suppress pathogens in the soil and reduce soil-borne diseases.

A fertilizer (American English) or fertiliser (British English) is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment or hand-tool methods.

The three primary elements of fertilizer are essential nutrients that plants require in relatively large amounts for healthy growth and development. These elements are nitrogen (N), phosphorus (P), and potassium (K), often referred to as NPK. Each of these nutrients plays a distinct and vital role in plant physiology.
Nitrogen is crucial for the growth of leaves and stems. It is a key component of chlorophyll, the compound that plants use in photosynthesis to convert sunlight into energy. Nitrogen also plays a significant role in the synthesis of proteins, enzymes, and other essential molecules. A deficiency in nitrogen typically results in stunted growth and yellowing of leaves.
Phosphorus is important for the development of roots, flowers, seeds, and fruits. It is involved in energy transfer within the plant, helping to convert sunlight into usable energy through photosynthesis. Phosphorus also aids in the formation of DNA and RNA, which are critical for cell division and growth. A lack of phosphorus can lead to poor root development and delayed maturity.
Potassium is essential for overall plant health and resilience. It regulates various physiological processes, including water uptake, enzyme activation, and photosynthesis. Potassium also enhances the plant’s ability to withstand stress, such as drought, disease, and cold temperatures. A deficiency in potassium often manifests as weak stems, poor fruit quality, and increased susceptibility to pests and diseases.
These three elements are the cornerstone of most fertilizers, and their balanced application is crucial for optimal plant growth and productivity. Fertilizers are often labeled with an NPK ratio, indicating the relative proportions of nitrogen, phosphorus, and potassium, to help gardeners and farmers choose the appropriate product for their specific needs.
