Company Introduction
Founded in Guangzhou, KSS is the coffee-technology brand of Guangzhou Wangneng Product Design Co., Ltd. — a company with 26 years of industrial design expertise and 16 years of additive manufacturing (3D printing) experience.
Our design-driven approach combines engineering precision with consumer insight. The KSS 60-Second Cold Brew Coffee Maker succeeded on Kickstarter, earned official recommendation from the Shenzhen International Coffee Expo, and is now in daily use by 30+ influencer coffee shops.
We focus on the North American market and seek long-term B2B partners worldwide: coffee importers, roasters, distributors and café procurement teams. We support wholesale, agency, custom packaging and OEM/ODM services.
The KSS 60-second cold brew coffee machine has achieved a successful crowdfunding on Kickstarter in 2025, and has received official recognition at the CAFEEX Shenzhen International Coffee Exhibition and the MFE Exhibition in Macau in 2026. It has also established stable partnerships with over 30 online celebrity coffee shops, and nearly 100 coffee baristas are currently using our KSS 60-second cold brew coffee machine. We look forward to more partners selling the KSS cold brew coffee machine to more countries and regions.
Technical Introduction
Patented Centrifugal Cold Brew Technology：Traditional cold brew takes 8–12 hours of overnight steeping. KSS patented centrifugal extraction completes the process in 60 seconds.
A 1,000 RPM motor drives coffee grounds and room-temperature water into rapid, thorough contact inside a sealed centrifugal chamber. Centrifugal force accelerates extraction, preserving volatile aromatic compounds while minimizing bitter compounds and chlorogenic acids. The result: a clean, naturally sweet, low-acidity cup.
The mechanism is protected under China Utility Model Patent No. ZL 2025 2 0937091.5 (Authorization No. CN 223987722 U).
Cold brew produced by KSS devices was independently tested by the Guangzhou Institute of Microbiology under GB 4789.2-2022. Aerobic bacterial count remained below 1 CFU/mL for up to 12 hours at both room temperature and 2–8°C refrigeration (Report No. WJ2026002505E(A)).
All KSS products carry CE, FCC and MSDS certifications, meeting North American market standards.
