Abstract: A soy milk coagulating device includes: a coagulation vessel with an internal volume of 1,000 cc or less; two electrode plates facing each other to form a pair in the vessel; and a power feed controlling mechanism for controlling electricity fed to the electrode plates, and in the soy milk coagulating device, the power feed controlling mechanism is composed of: a tofu control system which is provided to heat soy milk to a set temperature at an average heating rate of equal to or less than 8° C. per minute, or at an average heating rate of more than 8° C. per minute and equal to or less than 15° C. per minute, and to keep the soy milk at the temperature for at least 5 minutes; a yuba control system; and switching unit which is provided to switch between the two control systems.

Abstract: A process for producing a soybean milk and soybean milk pack includes cooking ground soybeans with the use of superheated steam containing no or little oxygen, thus extracting soybean proteins to give a cooked bean juice of the soybeans; separating a solid soybean curd lees in the oxygen-free state without cooling the bean juice to give a soybean milk containing no or little dissolved oxygen and having soybean proteins suspended therein. The process also includes filling the thus produced soybean milk into pack containers in an oxygen-free environment with no or little dissolved oxygen without heating or cooling the soybean milk, sealing the containers, and then storing at 1 to 10° C.
