Most soymilk machines with filter screens will inevitably have filter screen blockage. Cleaning the filter can refer to the following methods:

First, brush the filter carefully with a toothbrush or other brush after each use. If you don't clean it once, it won't work well next time, and it's not easy to brush bean dregs after drying.

Second, if the net is blocked, you can put the filter in hot water for a long time before brushing. If it is still clean, put the filter screen on the coal steam flame to carbonize the bean dregs stuck on the filter screen, and then brush it with a brush.

Of course, the filter screen will turn black, but it will not affect the use. Pay special attention to the temperature and don't burn the filter screen.
