The landlord's question is too vague. Health-preserving rice paste is only the function of a certain type of soymilk machine in Jiuyang, and it is used as a selling point. Jiuyang soymilk machine is a general term of a large category, and there are many models under it. The price I know ranges from 100 to 7800. I just bought a 5 10W jiuyang wangwang machine. Can make dry and wet soybean milk, whole grains, rice paste, fruit and vegetable cold drinks. In fact, rice paste and fruit and vegetable cold drinks are the most commonly used functions. When I bought it, I spent 380 yuan with the invoice.
