present design is smart IOT black bean tofu relates to a smart black bean jeondubueul things Internet-based smart black bean tofu manufacturing composite system of manufacturing that improves quality by using the manufacturing system, opening and closing sensor training supply pipe temperature action on the sensor tag, the mixer, the cause if the opening and closing sensor valve, the heat insulating cover heating element band is monitored at all times the state of the RFID tag attached to an air layer mixed steaming hopper consisting of a one-piece installation both in one vessel, and analyzes the data transmitted over the sense hayeoseo is then made real time, and interact with your smartphone, open sensor supply payipeueul through and training supply of the quantity of longitude zero, then injected the manufacturing soybean production around the soy hayeoseo stirred with a mixer and a certain amount of soybean active powder, stir and simultaneously insulation temperature of the cover heating element to the air layer effect of 98 RFID tag attached to an air layer mixed steaming hopper as the heat source of the band soybean former soy indirect heating by the quality and the manufacture is improved soybean steaming before soybean milk, soybean steaming before soybean milk in real time by the temperature sensor tag It is sent to your smartphone. The percentage of active soybean powder and the training is 1: 5.6 is preferred Mixer, after that the temperature sensor tags, the state of the RFID tag attached to a coagulant mixing hopper constructed as an integral opening and closing sensor valves all installed on one container real-time feedback to promptly find the cause of the degradation and correct the Black Bean steaming ago soy milk by Black Bean steaming former milk of 98 natural cooling after being transferred to the RFID tag attached to a coagulant mixing hopper opening through sensor baelbeueul, and whether the coagulant added an optimal temperature of 85 temper
