Lin Hsuan-li, a local resident of Nantou County’s Tsaotun Township, has developed a coffee percolator that brews coffee at a constant temperature. The design was apparently inspired by how his grandmother used to stew foods. The invention produces coffee with a robust aroma by maintaining an average temperature of around 94 degrees for eight minutes. All of his fellow coffee enthusiasts who have tried the coffee have expressed their admiration for the invention.

Lin, an employee at Tai Power Co (Taipower), received confirmation from the Ministry of Economic Affairs’ (MOEA) Intellectual Property Office last Wednesday that his percolator had been granted a utility model patent. He was beside himself with joy after spending the past six years developing the design and making improvements on it.

Lin has been drinking coffee for 43 years since the first time he drank it from a balancing siphon coffee maker at the age of 18. He has tried to think of ways to overcome the problem of variable temperatures affecting the quality of the brew. Around six or seven years ago, when he saw his wife cooking using a traditional stewing method, he reflected on the principle behind it, and this was what initially caused him to delve into the design for the percolator.

Lin came up with the design based on his expertise in electronics. The temperature inside the canister can be controlled. He says regardless of what type of coffee bean you use, the beans must be fresh. After being placed in the percolator for a minute to a minute and a half, it starts giving off the aroma of the coffee. After it is brewed at approximately 94 degrees for eight minutes, you can transfer the coffee to the upper canister of a balancing siphon coffee maker using a warmed up container. The coffee is ready after it has dripped down into the lower canister.
