If you are looking for a high moisture content organic waste dryer, sludge dryer, slurry dryer, methane fermentation digested liquid dryer, or waste recycling dryer, please consider KENKI DRYER.

KENKI DRYER can dry sticky materials that cannot be dried by others. KENKI DRYER can easily dry liquid materials. Some liquid materials are difficult to dry due to their strong adhesiveness, but the KENKI DRYER can dry them smoothly without clogging the dryer with its unique, world-patented mechanism.

The upcycling and recycling of organic waste from factory production is becoming increasingly important in terms of environmental protection and decarbonization.
KENKI DRYER uses steam from a boiler as a heat source for indirect low-temperature drying. Since it dries at low temperatures, the composition of organic waste is hardly changed, and it can be effectively used for upcycling and recycling, making zero-emission drying possible.

However, many organic wastes are difficult to dry due to their strong adhesive properties, and some other types of dryers may not discharge organic wastes due to clogging inside the dryer. KENKI DRYER’s unique world-patented mechanism allows it to dry even the most adhesive and sticky organic wastes with high water content smoothly without clogging the dryer.

When organic waste is left in a high-moisture state, decomposition is caused by the activity of microorganisms (especially bacteria and molds) contained in the organic waste. These microorganisms use the moisture and nutrients contained in the organic waste to reproduce, producing gases and odors in the process, and the growth of the microorganisms causes decomposition and the development of odors and pathogens. Drying is an effective way to solve these problems.
After drying, organic waste can be used as fertilizer, compost, soil conditioner, or feed for livestock such as cows and pigs, and bioplastics can be produced from plant-based organic waste as an alternative to petroleum-based plastics.

There is currently a shortage of wood in Japan. The use of dried organic waste as fuel instead of wood, or the use of dried organic waste as biochar or biocoke by carbonization, is attracting much attention. For example, biochar is used as a soil amendment or activated carbon, while bio-coke is used as a reductant or deoxidizer to replace coke in the steel and foundry industries.

Biochar and bio-coke are carbonized materials derived from biological resources that are effective in revitalizing organisms and improving the environment. Please contact us for more information on carbonization as our pyrolysis equipment, Biogreen, does not use fossil fuels and does not emit CO2, a global warming gas.

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 generated during drying.
The KENKI DRYER is a continuous dryer, not a batch dryer that stores and dries materials to be dried. Therefore, operation is simple and unmanned operation is possible 24 hours a day.

Drying organic waste reduces its weight, which in turn reduces the amount of waste, which in turn reduces the cost of industrial waste, which is rising due to the recent trucking problem in 2024, and also reduces carbon dioxide emissions by reducing the number of trucks transporting waste, thereby contributing to environmental protection and decarbonization.

KENKI DRYER can dry sticky and adhesive materials that others cannot dry. KENKI DRYER is a breakthrough drying device with a total of 11 patents (2 in Japan and 9 in 7 overseas countries). Please consider KENKI DRYER for your high moisture organic waste dryer, sludge dryer, slurry dryer, methane fermentation digestate dryer, and waste upcycling or recycling dryer.

KENKI DRYER has been granted 11 patents in 8 countries (Japan, Taiwan, USA, France, Germany, UK, Switzerland, Canada).

Drying liquids is difficult due to several physical and chemical properties of liquids and the processes involved in their evaporation and removal. Here are some key reasons:

1. Latent Heat of Vaporization: Liquids require a significant amount of energy to change from a liquid state to a gaseous state. This energy is known as the latent heat of vaporization. Providing this energy in a controlled and efficient manner can be challenging.

2. Evaporation Rate: The rate at which a liquid evaporates depends on factors like temperature, humidity, air flow, and the surface area of the liquid. Ensuring optimal conditions for evaporation can be complex and resource-intensive.

3. Boiling Point: Different liquids have different boiling points. Some liquids, like water, have relatively high boiling points, which means they need more energy and higher temperatures to evaporate completely.

4. Heat Sensitivity: Some liquids are sensitive to heat and can degrade or react when exposed to high temperatures. This makes it difficult to apply enough heat to evaporate the liquid without altering its composition or properties.

5. Surface Tension and Viscosity: Liquids with high surface tension and viscosity can form films or droplets that resist evaporation. Breaking these films or spreading the liquid to increase the surface area can be challenging.

6. Containment and Collection: When drying a liquid, the resulting vapor needs to be collected or vented safely. This requires proper containment and ventilation systems, which can add to the complexity and cost of the process.

7. Impurities and Mixtures: Liquids often contain dissolved solids, impurities, or are part of mixtures. These components can affect the evaporation process, sometimes leading to incomplete drying or the formation of residues.

8. Phase Changes and Equilibrium: Liquids in a drying process can reach an equilibrium state where the rate of evaporation equals the rate of condensation. Overcoming this equilibrium to achieve complete drying requires careful control of environmental conditions.

Each of these factors can make the process of drying liquids intricate and demanding, requiring specialized equipment and techniques tailored to the specific properties of the liquid being dried.

Drying liquid organic waste is an important process for several reasons, including environmental, economic, and practical considerations. Here are some of the key reasons for drying liquid organic waste:

1. Volume Reduction: Drying significantly reduces the volume and weight of the waste, making it easier and more cost-effective to handle, transport, and store. This is especially important for industries that produce large quantities of liquid waste.

2. Stabilization: Drying can help stabilize organic waste by reducing the moisture content, which in turn reduces the risk of microbial activity, decomposition, and odor production. This makes the waste less hazardous and more manageable.

3. Waste Minimization: Reducing the moisture content in organic waste helps minimize the overall amount of waste that needs to be treated or disposed of. This is in line with waste management strategies that aim to reduce, reuse, and recycle.

4. Resource Recovery: Dried organic waste can often be used as a resource. For example, it can be processed into biochar, a valuable soil amendment, or used as a feedstock for producing biofuels or biogas through anaerobic digestion or pyrolysis.

5. Environmental Protection: Properly dried and managed organic waste reduces the risk of leachate formation, which can contaminate soil and water sources. This helps protect the environment and comply with regulatory requirements.

6. Cost Savings: Drying can lead to cost savings in waste management by reducing transportation costs, tipping fees at disposal sites, and the need for additional treatment processes.

7. Energy Recovery: Some dried organic wastes have a high calorific value and can be used as a fuel source in waste-to-energy plants. This provides an alternative energy source and helps reduce reliance on fossil fuels.

8. Improved Handling: Dried waste is generally easier to handle and process. It can be more easily mixed with other materials, stored for longer periods without degradation, and used in various applications without the issues associated with liquid waste.

By drying liquid organic waste, these benefits contribute to more sustainable and efficient waste management practices, ultimately helping to protect the environment and conserve resources.

Organic waste is any material that comes from plants or animals and can decompose naturally. This means that it can be broken down by microorganisms, such as bacteria and fungi, into simpler organic matter. Organic waste is a major component of municipal solid waste, and it can be a valuable resource if it is composted or recycled.

Here are some examples of organic waste:

• Food scraps, such as fruit peels, vegetable trimmings, and coffee grounds
• Yard trimmings, such as leaves, grass clippings, and branches
• Manure from animals
• Paper products, such as cardboard and newspapers
• Wood scraps

Organic waste can be composted to create a nutrient-rich soil amendment that can be used to improve plant growth. It can also be anaerobically digested to produce biogas, which can be used as a renewable energy source.

There are three main reasons for drying organic waste

1. Prevention of decomposition

If organic waste is left in a high moisture state, it can decompose due to microbial growth, causing foul odors and pathogens. Drying is an effective way to solve these problems.

Drying reduces the water activity of organic waste. Water activity is an indicator of the amount of water available to microorganisms, and generally speaking, microbial growth is inhibited when water activity falls below 0.6.

Specifically, the following effects can be expected

・Inhibition of microbial growth: Decreased water activity inhibits the growth of microorganisms such as bacteria and molds that cause spoilage.
・Decrease in enzyme activity: Many enzymes are activated in water, but drying inhibits their activity and slows the decomposition of organic matter.
・Inhibition of chemical reactions: Many of the chemical reactions involved in decomposition require water, and drying inhibits these reactions.

2. volume and weight reduction

Drying organic waste can significantly reduce its volume and weight.

For example, the moisture content of food waste is approximately 60-80%, but drying can reduce the moisture content to less than 10%. This means a reduction of approximately one sixth in volume and one quarter in weight.

This helps to reduce the cost of waste disposal and improve the efficiency of transportation and storage.

3. resource recovery

Dried organic waste can be used for several purposes

Fuel: The dried material itself can be used as fuel or converted to biogas for use as fuel.
Fertilizer: The dried organic waste can be composted or used as a soil amendment.
Feed: Can be used as livestock feed.
Other: Can be used as a raw material for paper, fiber, plastics, etc.

Thus, drying organic waste offers a variety of benefits, including reduced environmental impact, cost savings, and resource recovery.

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.

Source：Wiki Fertilizer

The three primary elements of fertilizer, essential for plant growth and commonly referred to as macronutrients in the context of plant nutrition, are:

Nitrogen (N):
Function: Promotes leaf and stem growth, as it is a crucial component of chlorophyll, the compound that plants use in photosynthesis to convert sunlight into energy. Nitrogen is also a key part of amino acids, the building blocks of proteins.
Deficiency Symptoms: Yellowing of leaves (chlorosis), stunted growth, and poor yield.

Phosphorus (P):
Function: Essential for energy transfer and storage in plants, as it is a component of ATP (adenosine triphosphate). Phosphorus also plays a vital role in root development, flowering, and seed production.
Deficiency Symptoms: Dark green or purplish leaves, delayed maturity, and poor root development.

Potassium (K):
Function: Regulates various metabolic activities in plants, including photosynthesis, protein synthesis, and water regulation. Potassium is also important for improving disease resistance and overall plant health.
Deficiency Symptoms: Leaf edges may turn yellow or brown (scorching), weak stems, and reduced resistance to drought and diseases.
Fertilizers are often labeled with an N-P-K ratio, which indicates the relative proportions of these three essential nutrients. For example, a fertilizer labeled as 10-20-10 contains 10% nitrogen, 20% phosphorus, and 10% potassium.

Bioplastics are a type of plastic derived from renewable biological sources, such as vegetable fats and oils, corn starch, straw, woodchips, sawdust, and recycled food waste. Unlike conventional plastics, which are made from petroleum-based raw materials, bioplastics are made from biomass. There are several types of bioplastics, each with different properties and applications.

Types of Bioplastics

1. Bio-based plastics: Made partially or wholly from biological sources. Examples include:

   • Polylactic Acid (PLA): Derived from corn starch or sugarcane, used in packaging, disposable cutlery, and medical implants.
   • Polyhydroxyalkanoates (PHA): Produced by bacterial fermentation of sugars or lipids, used in medical devices and packaging.

2. Biodegradable plastics: These can be broken down by microorganisms into water, carbon dioxide, and biomass under certain conditions.

   • Starch Blends: Composed of starch mixed with other biodegradable polymers.
   • Polybutylene Succinate (PBS): Biodegradable plastic made from succinic acid and 1,4-butanediol.

3. Compostable plastics: These biodegrade under composting conditions within a specific timeframe.

   • Polylactic Acid (PLA): When used in compostable products, it can break down in industrial composting facilities.

Advantages of Bioplastics

• Reduced Carbon Footprint: Production often generates fewer greenhouse gas emissions compared to conventional plastics.
• Biodegradability: Some bioplastics can decompose in natural environments, reducing litter and pollution.
• Renewable Resources: Made from plant-based materials, which can be sustainably grown and harvested.

Challenges and Considerations

• Cost: Often more expensive to produce than conventional plastics.

Bioplastics are a type of plastic derived from renewable biological sources, such as vegetable fats and oils, corn starch, straw, woodchips, sawdust, and recycled food waste. Unlike conventional plastics, which are made from petroleum-based raw materials, bioplastics are made from biomass. There are several types of bioplastics, each with different properties and applications.

Biodegradable plastic is a type of plastic that can be broken down by living organisms, typically microbes, into simpler substances like water, carbon dioxide, and biomass. It’s one kind of bioplastic, but the terms aren’t exactly interchangeable.

Here’s the key difference:

• Bioplastic: This refers to the origin of the plastic. It’s made from renewable sources like plants or microorganisms (bio-based). Not all bioplastics are biodegradable.
• Biodegradable Plastic: This describes the end-of-life of the plastic. It can be broken down by living things under certain conditions (e.g., composting facilities).

So, all biodegradable plastics are bioplastics, but not all bioplastics are biodegradable.

Here are some additional details about biodegradable plastics:

• Materials: They can be derived from various renewable sources like corn starch, cellulose, or even be made with the help of microorganisms.
• Benefits: Biodegradable plastics offer an advantage over traditional plastics by decomposing in a reasonable timeframe, potentially reducing plastic pollution in landfills.
• Considerations: Biodegradable plastics often require specific conditions for breakdown, such as industrial composting facilities. Improper disposal might not lead to biodegradation and could still cause environmental issues.

Overall, biodegradable plastics are a promising development for reducing plastic waste, but it’s important to understand their proper use and limitations.

Both biochar and bio-coke are products derived from organic materials, but they have some key differences:

Processing Temperature:

• Biochar: Produced at lower temperatures (typically around 300-700°C) through a process called pyrolysis. Limited oxygen is present during pyrolysis.
• Bio-coke: Produced at higher temperatures (around 700-1000°C) in an almost complete absence of oxygen. This higher temperature process is more similar to coal coking.

End Product:

• Biochar: A porous and lightweight material with a high surface area. It’s rich in carbon but can also retain some nutrients from the original biomass.
• Bio-coke: Denser and has a higher carbon content compared to biochar. It shares some similarities with traditional coke in terms of physical properties.

Applications:

• Biochar: Primarily used for soil amendment. Its porous structure helps retain water and nutrients, improving soil health. It can also be used for filtration, as a source of renewable energy, and for capturing pollutants.
• Bio-coke: Intended as a sustainable substitute for coal coke in industrial processes, particularly steelmaking. It provides carbon and heat, similar to coal coke, but with potentially lower greenhouse gas emissions.

Here’s a table summarizing the key differences:

Feature	Biochar	Bio-coke
Processing Temperature	Lower (300-700°C)	Higher (700-1000°C)

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.
