Dry What Others Can’t.
KENKI DRYER, designed and manufactured with internationally patented technologies (11 patents in 8 countries), can easily, safely, and surely dry materials that no other dryer can handle — including sticky, adhesive, viscous, and high-moisture materials, even in liquid form.
Using saturated steam as its only heat source, KENKI DRYER achieves high drying efficiency at low temperatures, preserving the components of the materials while ensuring uniform, stable, and safe drying. Its unique structure, certified under international patents, prevents clogging and enables continuous 24-hour unattended operation — making it ideal for industrial sludge drying, slurry drying, beverage lees drying, and organic waste upcycling.
Unlike conventional dryers, KENKI DRYER consumes only a small amount of steam.
By using surplus factory steam or an electric boiler, no CO₂ or greenhouse gases are emitted during operation, contributing to carbon-neutral and sustainable manufacturing.
Its simple structure minimizes replacement parts, ensures long-term reliability, and keeps both initial and running costs low.
KENKI DRYER is an indirect steam dryer unlike any other.
Its patented combination of conductive heat transfer and heated-air circulation achieves superior thermal efficiency and consistent product quality.
Many companies have adopted KENKI DRYER for its:
KENKI DRYER enables low-temperature drying and upcycling of high-moisture organic materials such as coffee grounds, used tea leaves, beverage lees, and organic residues.
These materials can be reused as fuels, fertilizers, or soil conditioners, creating both economic value and environmental benefit.
With offices and partners in Europe, Southeast Asia, and Taiwan, KENKI Corporation continues to expand globally, delivering innovative and sustainable drying solutions to industries around the world.
