我有个朋友代了个豆浆机从国内.The procedure for making soy milk is similar to your description. But she told me that there are 3 drawbacks:
1. clean procedure is not very easy. Take time.
2. taste is not very good, since the mesh of filter is not very delicated.
3. easily overflow.
Now she just put it aside and never use it.
I am not sure if your machine has avoided these drawback. I don't want to trouble your business. Just like to remind all interested customers
