The first specific implementation way is as follows: the embodiment is described with reference to fig. 1 to 2, and the device for separating and extracting soybean protein for laboratory comprises a precipitation tank 1, an ultrafiltration tank 2 and a pump 3;
the sedimentation tank 1 consists of a tank body 11, a stirring mechanism and a heating device; the stirring mechanism consists of a motor 13 and a stirring paddle 14; the motor 13 is arranged at the top of the tank body, and a power output shaft of the motor 13 is connected with a rotating shaft of the stirring paddle 14; the stirring paddle 14 is arranged in the tank body 11; a heat-insulating layer 15 is arranged on the outer side of the tank body 11, and a heating cavity 16 is formed between the heat-insulating layer 15 and the tank body 11;
the heating device consists of an electric heater 121 and a resistance wire 122; the resistance wire 122 is positioned in the heating cavity 16, and the electric heater 121 is positioned at the bottom of the heat-insulating layer 15;
the liquid inlet of the ultrafiltration tank 2 is communicated with the liquid outlet of the sedimentation tank 1 through a liquid inlet pipe;
a multi-layer filter membrane 6 is arranged in the ultrafiltration tank 2; the liquid inlet of the pump 3 is communicated with the circulating liquid outlet of the ultrafiltration tank 2, and the liquid outlet is communicated with the liquid inlet of the ultrafiltration tank 2.
In this embodiment, the material is placed in the tank body 11 through the feed port 112, the acid-base adjustment is performed through the acid-base adjustment feed port 111, and the pH of the material liquid in the tank body 11 is monitored by the pH meter 7. The soybean material liquid of which the protein is to be extracted is continuously stirred by the stirring paddle 14. Meanwhile, the electric heater 121 is turned on, the heating liquid (e.g., water) injected into the heating cavity 16 is heated by the resistance wire 122 (the heating liquid is injected through the water inlet 151 and is guided out through the water outlet 152), so that the feed liquid in the tank body 11 is heated and heated, the temperature of the feed liquid is monitored by the temperature sensor 8 (e.g., a thermometer), if the temperature is too high, a part of the heating liquid can be guided out through the water outlet 152, and a part of new heating liquid is injected again through the water inlet 151 to cool. The insulating layer 15 can serve the purpose of preventing heat from dissipating.
The third valve 413 is opened to introduce the crude protein slurry after alkali dissolution and acid precipitation into the ultrafiltration tank, and the first liquid inlet pipe 41 or the second liquid inlet pipe 42 can be selected to introduce the crude protein slurry into the ultrafiltration tank according to actual conditions.
