KENKI DRYER – The Future of Sustainable Drying
As the demand for sustainable and efficient drying solutions grows, KENKI DRYER stands out as the ultimate choice for drying barley tea lees and other high-moisture organic materials.

KENKI DRYER makes it easy to dry barley tea lees that cannot be dried with other types of dryers.

There are various types of barley tea, and historically, six-row barley, two-row barley, and adlay have been used.
By drying the barley tea lees produced after barley tea production at low temperatures, it is possible to use them as upcycled products with minimal changes in their composition after drying. The KENKI DRYER is an indirect drying system that uses steam as a heat source at low temperatures, so there is minimal change in the composition of the dried material after drying, making it possible to recycle and fully utilize it as an upcycled product.

In recent years, barley tea has attracted renewed attention due to growing health consciousness, and the market is expanding rapidly. Barley tea does not contain caffeine, so it does not have a diuretic effect. In addition, barley tea contains polyphenols, and it is also expected to be effective in preventing lifestyle-related diseases.
Barley tea is also popular in seasons other than summer. However, it is said that there is not as much demand for it in the off-season as there is in the summer. For example, according to a 2019 survey, 88% of people drink barley tea in the summer, while about half of people drink barley tea in the winter.

Barley tea are rich in crude protein, fiber, and minerals, and can be used as livestock feed for cattle and pigs, or as fertilizer, compost, or soil amendment in fields. In addition, dried barley tea lees contain vitamin C and polyphenols, and these ingredients can be useful for beauty and health. For example, they can be used as ingredients in cosmetics and health foods.

Drying barley tea lees reduces their weight, which in turn reduces the amount of waste materials produced, which in turn reduces the cost of industrial waste, which is rising due to the recent trucking problem in 2024.

If barley tea lees are left in a state of high moisture content, they will begin to rot due to the activity of the microorganisms (especially bacteria and mold) they contain. These microorganisms will use the moisture and nutrients contained in the barley tea lees to multiply, and in the process they will produce gas and foul odors, causing the lees to rot and become a source of foul odors and pathogens. Drying is an effective way to solve these problems.

However, in the case of barley tea lees dryers, the sugar and starch contained in barley tea lees can cause them to stick to the inside of the dryer, clogging it and preventing them from being discharged. This effect is particularly noticeable when drying at low temperatures. The KENKI DRYER uses a unique, world-patented technology that makes it possible to easily dry any type of barley tea lees at low temperatures without clogging the dryer, and the dried lees can be easily discharged after drying.

Wood is currently in short supply in Japan. The use of dried beverage lees such as barley tea lees as fuel instead of wood, or the use of dried beverage lees 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. We can provide carbonization services using our Biogreen pyrolysis equipment, which does not use fossil fuels and does not emit CO2, a greenhouse gas, from the equipment.

KENKI DRYER, with 11 patents in 8 countries, is an indirect steam dryer, but it is a completely unique product that is 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, and the dryer does not emit carbon dioxide during drying, allowing for decarbonized drying. Alternatively, by installing electric boilers or hydrogen fuel boilers, no greenhouse gases or CO2 emissions are generated during drying.
In addition, there have been no problems since it was put into operation, and because the dryer’s main body blades rotate at a very slow speed of 5 RPM or less, there is little wear on the parts, making maintenance easy and inexpensive. The KENKI DRYER is a continuous drying system that stores and dries the product to be dried and is not a batch system. Therefore, it is easy to manage and can operate unattended 24 hours a day.

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.

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.

Source：Wiki Compost

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 are:

Nitrogen (N): Nitrogen is essential for plant growth and development, particularly for the growth of stems and leaves. It is a key component of chlorophyll, the green pigment in plants that is responsible for photosynthesis.

Phosphorus (P): Phosphorus plays a vital role in the development of roots, flowers, and fruits. It is also important for the transfer of energy within the plant.

Potassium (K): Potassium helps plants regulate water balance, improve disease resistance, and enhance overall growth and vigor. It is also important for the development of strong stems and branches.

These three elements are often referred to as the “NPK” nutrients and are always listed in that order on fertilizer labels. The numbers on a fertilizer label represent the percentage of each nutrient in the product. For example, a fertilizer labeled 10-20-10 contains 10% nitrogen, 20% phosphorus, and 10% potassium.
