[Task] High-quality soymilk is produced, with overflow of foam or bubbles avoided in an extracting step, and the extractability (extraction ratio) of the soymilk is simultaneously heightened. [Solving Means] An apparatus for producing soymilk includes heating units H1 and H2 for heating a soybean soup go1; a defoaming unit F for defoaming a heated soybean soup go2; an extracting unit B for separating a defoamed soybean soup go3 into soymilk Tn1, bean curd refuse Tn2 and a liquid residue Tn3; and pipe lines u11 and u12 for returning the separated liquid residue Tn3 to a position before the defoamng unit F or behind the heating unit H2 (H1) and feeding it again to the defoaming unit F, wherein the pipe lines u11 and u12 for feeding the separated liquid residue to the defoaming unit F are connected to a liquid residue discharge port B3j of the extracting unit B from which the liquid residue Tn3 having been separated is taken out. The liquid residue Tn3 is then fed forcibly to the defoaming unit F again with a transfer pump P4. |
