What Okawara Mfg. Co., Ltd. does

Okawara Mfg. Co., Ltd. is a Japanese industrial equipment manufacturer founded in 1927 and headquartered in Yoshida-cho, Haibara-gun, Shizuoka Prefecture. The company designs and manufactures custom drying, granulation, mixing, liquid concentration, and sterilization equipment, organized around flagship proprietary platforms including the EVAPOR spinning cone centrifugal thin-film vacuum evaporator (residence time under one second at temperatures as low as 35°C, with 620+ units delivered worldwide), the RIBOCONE conical ribbon mixer dryer (combining mixing, drying, cooling, vacuum drying, and heat treatment in a single vessel with externally mounted drive to prevent lubricant contamination), the KPU and SIRV superheated steam continuous sterilization systems (operating in 3-10 seconds), the FV DRYER multi-functional conical filter vacuum dryer, and a family of fluid bed, rotary, slurry, and sludge dryers. Applications span food and beverage, pharmaceutical and nutraceutical, organic and inorganic chemicals, feed and fertilizer, industrial and municipal sludge, and biomass resource processing.

The company monetizes primarily through one-off hardware sales of custom-engineered capital equipment, priced on a quote basis against customer specifications, supplemented by pilot plant testing services and remote video testing as a pre-sales engagement tool. It maintains a 292-employee organization as of end-December 2025 and holds 124 granted patents and 22 pending applications. Go-to-market is enterprise field sales via direct offices in Tokyo, Osaka, Shizuoka, and Nagasaki in Japan, supplemented by wholly-owned subsidiaries in Shanghai (China, since 2003, restructured in 2019) and Bangkok (Thailand, established 2025), with channel partnerships covering Europe (Nol-Tec Europe, NTE Process Srl), the United States (HAF Equipment), and Taiwan (EVER TECH). Okawara is family-owned, privately held with no parent company or external institutional investors, completed a generational leadership transition in April 2026 with Ayano Okawara assuming the presidency, and exited its South Korean subsidiary in 2023 while expanding ASEAN presence.

Products and services

• EVAPOR (Spinning Cone Centrifugal Thin-Film Vacuum Evaporator) Concentration of heat-sensitive, viscous and high-value products using spinning cone centrifugal thin-film vacuum evaporation technology. Spreads liquid in thin layers of 0.1mm or less, achieving residence time below one second at temperatures as low as 35 degrees Celsius, with centrifugal force preventing foam formation. Used for food, nutraceutical, pharmaceutical and chemical concentration applications.
• RIBOCONE (Conical Ribbon Mixer Dryer) Multi-purpose conical ribbon equipment combining mixing, drying, cooling, vacuum drying, filtration, and heat treatment in a single vessel. Drive and gearbox are located outside the vessel to prevent product contamination from lubricants, and no bottom bearing ensures complete product discharge. Suited to chemical, food, and pharmaceutical powder processing applications.
• KPU (Superheated Steam Continuous Sterilization System for Powder and Grains) Continuous sterilization of powder and granular materials in 4 to 5 seconds using superheated steam, with steam recycling through circulation for energy efficiency. Designed for food ingredient and pharmaceutical powder sterilization applications.
• SIRV (Superheated Steam Continuous Sterilization System Exclusive for Grains) Compact, cost-efficient continuous sterilization system for grain materials using Okawara's in-house designed high-pressure rotary valve, achieving 3 to 10 second sterilization. Designed for grain and cereal processors.
• FV DRYER (Multi-functional Conical Filter Vacuum Dryer) Multi-functional conical dryer performing filtration, drying, rinsing, and mixing in a single unit. With no agitator installed, suitable for pharmaceuticals and fine-chemical materials requiring sanitary operation.
• HORIZONTAL FLUID BED DRYER Continuous fluid bed dryer with rectangular process chamber for materials that move horizontally from inlet to outlet port during drying. Used for granular and powder drying applications across food, chemical, and feed industries.
• SLURRY DRYER (Fluid Bed Dryer Using Ceramic Balls) Fluid bed dryer using 1-3mm diameter ceramic balls as auxiliary heating medium. Product sticks to ball surfaces, gets dried by conduction and convection heat, then is peeled off by collision. Designed for slurry and paste drying applications.
• SUPER ROTARY DRYER (with Disintegrator) Rotary dryer with disintegrator in the rotating drum designed to effectively contact material with hot air. Capable of drying dewatered cake, muddy, sludge, and solid materials into granular product. Used for municipal, industrial, and feed applications.
• SLUDGE DRYER (with Disintegrator) Rotary drum dryer with disintegrator for sludge drying from wastewater treatment plants, active sludge, coagulated sedimentation sludge, human waste, sewage, and water purifying plants. Over 2,000 units have been supplied worldwide since the 1964 original launch.
• INNER TUBE ROTARY (Continuous Conduction Heat Dryer) Continuous conduction heat dryer with multi-tubular heating pipe bundle rotating inside a fixed shell. Small clearances between lifters and shell promote mixing without stagnation. Suited to sewage sludge, drinking water sludge, eco feeds, and waste materials.
