The invention provides a manufacturing method of a soybean milk-like drink and a soybean curd, and an airstream grinding device to use for the manufacturing method, wherein the soybean milk-like drink and the soybean which are rich in healthy functional components, flavor and mouth feel can be manufactured through a simple equipment structure in a low-power, low-cost and short-time manner. The manufacturing method comprises the following steps: a blank hypocotyl powder preparing step with the procedures of drying raw soybeans, peeling, taking out the hypocotyls, heating the hypocotyls, performing air current crushing on the hypocotyls at a temperature below 55 DEG C, fine-crushing to hypocotyl powders of which the median diameter (d50) is 20-40 mu m and the proportion of the powders with diameter below 100 mu m is higher than 90% a soybean powder preparing step of performing air current crushing on the soybeans without hypocotyls, and fine-crushing to soybean powders of which the median diameter (d50) is 20-40 mu m and furthermore the proportion of the powders with diameter below 100 mu m is higher than 90% and a raw material mixing step of mixing 0.05-2wt% of the hypocotyl powder and 2-22wt% of the soybean powders, thereby preparing the soybean milk-like drink.
