Ohkawara Kakohki

What Ohkawara Kakohki does

Ohkawara Kakohki Co., Ltd. (大川原化工機株式会社) is a Japanese specialty engineering company that designs, manufactures, and sells industrial spray dryers, spray coolers, and related particle processing equipment. Founded in March 1980 and headquartered in Yokohama with a 102-person workforce as of April 2025, the company has accumulated approximately 2,500 spray dryer installations globally (~2,000 in Japan, ~500 overseas) across four primary verticals: ceramics and electronic materials, food processing, pharmaceuticals, and chemicals, with a secondary position in industrial waste liquid treatment. Customers are unnamed enterprise manufacturers; application examples include fine ceramic powders for mobile phone and computer components, powdered foods (milk, coffee, miso, seasonings), pharmaceutical APIs and excipients, battery cathode/precursor materials, and industrial chemical powders.

The company's core technology centers on three integrated processes — liquid atomization, drying, and particle design — supported by a portfolio of patented components including the Sharp Edge disc atomizer, M-Type Disc, Twin Jet Nozzle, Pressurized Two-Fluid Nozzle, and Low Cap collection system. Product families span the L/OC general-purpose series, F and M ceramics-focused series, the Spray Bag Dryer (developed jointly with TDK to eliminate metal contamination), CL/COC and PL-2/CPL-2 nitrogen closed-circulation models for organic solvents, FGA fluidized granulation units, Twin Jetter NL/RL micro-particle R&D and production models, and original environmental equipment (GASTEM exhaust cooling, zero-drainage systems, SBR superheated steam sterilizers, RH spray pyrolysis, Free Micro Mixer, spray coolers). Engineering validation is anchored by the Powder Technology Research Institute in Fujinomiya, which holds 16 pilot-scale test machines used for customer feasibility studies and collaborative R&D.

The business model is B2B capital equipment sales with high customization: customers follow a structured sales process from inquiry through pilot testing, proposal, design, manufacturing, installation, and commissioning, with pricing on a quote basis. Revenue is generated primarily from one-time custom/OEM and standard-model spray dryer sales, supplemented by aftermarket maintenance, modernization, parts, and paid testing services at the Fujinomiya institute. Domestic Japan sales run through the Yokohama HQ and Osaka office; international sales leverage wholly-owned subsidiaries in Suzhou and Korea, the Shanghai joint venture (established 1996), and authorized sales agents in Taiwan, Italy, the USA, and India. The company holds ISO 9001 and ISO 14001 certifications and operates with no institutional VC/PE backing; ownership remains family-controlled under the Ohkawara family.
