The most difficult part to clean in traditional soymilk machines is the dense and fine filter. There are always bean dregs embedded in it. No matter how hard you scrub, it is not easy to clean, which is time-consuming and labor-intensive. The design of Joyoung soybean milk machine abandons the traditional filter and adopts a nozzle-type Rafal mesh design, which is based on the famous "Rafal mesh" principle in fluid mechanics (this nozzle that first shrinks and then expands is called Rafal tube) to achieve full cycle fine refining. In other words, using this technology, you can basically drink even bean dregs.
