Why is the soymilk ground by the soymilk machine different from the bagged soymilk bought in the supermarket? The bag is thin, compared with the traditional one, it is very thick now.

That's because soybean milk is made of bean dregs. Whether it is ground by hand before or now, it will be better to drink it when it is separated. Bean dregs are easy to precipitate, so you can't drink it without separation. This was the case when my soymilk machine was first made. It feels a little rustling without stirring with a spoon, so it is nutritionally better, and then it will slowly precipitate at the bottom, eliminating the trouble of washing the soybean milk net, which is nutritious and convenient.
