An apparatus for producing soymilk includes heating units for heating a soybean soup, a defoaming unit for defoaming a heated soybean soup, an extracting unit for separating a defoamed soybean soup into soymilk, bean curd refuse and a liquid residue, and pipe lines for returning the separated liquid residue between the defoaming unit and the heating unit to refeed the separated liquid residue to the defoaming unit. The pipe lines for refeeding the separated liquid residue to the defoaming unit are connected to a liquid residue discharge port of the extracting unit from which the separated liquid residue is taken out and refed to the defoaming unit with a transfer pump.
