ENKI DRYER: The Ideal Solution for Drying Green Tea Lees
Overview
With world-patented technology, it is possible to dry sticky substances that cannot be dried with other dryers. Japan primarily produces green tea, including varieties like sencha, gyokuro, kabusecha, tencha, matcha, and gyokurocha. Among these, tencha is ground to make matcha. Green tea consumption trends show a decline in loose-leaf tea and an increase in bottled green tea beverages.

Low temperature drying of green tea lees with KENKI DRYER
Most of the tea produced in Japan is green tea. There are several types of green tea, including sencha, gyokuro, kabusecha, tencha, matcha, and gyokurocha. Tencha and matcha are different: matcha is made by grinding tencha into a fine powder in a tea mill or similar device. In addition, gyokuro, kabusecha and tencha are collectively referred to as “aoicha”.
Consumption of green tea (leaf tea) is declining, while consumption of green tea beverages is increasing.
The annual amount spent per household on green tea (leaf tea) and tea beverages is decreasing for leaf tea but increasing for tea beverages. The total amount is about 11,000 yen and has remained the same in recent years. Leaf tea is tea made from tea leaves, while green tea beverages are beverages made from green tea leaves, such as sencha, which are extracted or infused and then bottled.
If green tea lees are left in a state with a lot of moisture, they will begin to rot due to the activity of microorganisms (especially bacteria and mold) contained in them. These microorganisms use the moisture and nutrients contained in the green tea lees to multiply, producing gas and foul odors, causing the green tea lees to rot and giving rise to foul odors and pathogenic bacteria. Drying is an effective way to solve these problems.
Green tea waste is rich in nutrients such as nitrogen, phosphorus and potassium and is used as fertilizer, compost and soil conditioner in tea gardens and fields. They are also used as feed for livestock such as cattle and pigs.
The upcycling and recycling of organic waste such as green tea lees is becoming more and more important from the perspective of environmental protection and decarbonization, and the demand for it will only increase.
The heat source for KENKI DRYER is steam from a boiler, and it is a low-temperature indirect drying process. Since it is a low-temperature drying process, there is little change in the composition of the green tea lees, so it can be effectively used for upcycling, and zero-emission drying is possible.
Drying green 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.
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 an electric boiler, 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.
