Product Adoption Case No. 4 [Blossom Coffee] Pinch Valve

Identify the cause of the malfunction and contribute to problem-solving! Adopted by professional coffee brewers, a custom pinch valve with excellent heat resistance.

Blossom Coffee is a design and development company based in San Francisco, USA, specializing in coffee equipment. Their newly developed coffee brewer is a professional-grade product that can control the supply temperature of the coffee beans and water, which significantly affects the taste and aroma of the coffee, within a range of 50 to 95°C in increments of 0.5°C. It has been featured on television networks such as ABC and BBC in the United States and is also sold in Japan. **Challenges and Solutions** The initial prototypes of the coffee brewer were equipped with pinch valves from other manufacturers, but frequent malfunctions occurred, prompting the company to seek our assistance. Our engineers determined that the cause of the malfunctions was the temperature rise inside the device due to the heat from the water. To resolve the issue, we proposed a product that uses custom coils with higher heat resistance than standard products, which was accepted. The customer was very satisfied with our prompt response and the resolution of the problem compared to traditional valve manufacturers. The development of the coffee brewer was completed as scheduled, and it was successfully launched at the end of 2015.
