[0025] The utility model will now be further described in conjunction with the accompanying drawings.

[0026] The present invention provides a silk protein emulsification device for use in a laboratory. Figure 1 As shown, the silk protein emulsification device used in the laboratory includes a base 11 and a container 15, the upper end of the base 14 fixedly supports the container 15, the upper end of the container 15 is open and the opening is detachably closed by a top cover 1, a rotating separation component 6 is rotatably arranged in the middle of the container 15, a heating reaction chamber 13 and an emulsification reaction chamber 14 are formed inside the container 15 through the rotating separation component 6, a heating component 3 is arranged in the heating reaction chamber 13, a liquid adding pipe 5 and a liquid discharging pipe 8 are arranged on the side wall of the emulsification reaction chamber 14, the height of the liquid adding pipe 5 is higher than the height of the liquid discharging pipe 8, a liquid discharging valve 4 is arranged on the liquid discharging pipe 8, and also includes a motor 10 and a stirring rotor 9, the stirring rotor 9 is arranged in the emulsification reaction chamber 14, the motor 10 is arranged at the lower end of the container 15, and the output shaft of the motor 10 is rotatably sealed through the bottom of the container 10 to be connected to the stirring rotor 9.

[0027] Exemplarily, the container 15 is a tube with one end closed and the other end open, and the rotating separation component 6 is a valve component installed in the middle of the tube to form a heating reaction chamber and an emulsification reaction chamber inside the container. The valve component can be a hand valve or a solenoid valve.

[0028] The operation process of using the silk protein emulsification device to obtain a silk protein solution comprises the following steps:

[0029] Step 1. Cut the cocoon to remove the pupa, then put the cocoon after removing the pupa into the heating reaction chamber 13, add an appropriate amount of reaction liquid in proportion, cover the top cover 1, turn on the heating component 3, heat the mixed liquid of the internal solution and the cocoon, and finally achieve complete dissolution of the cocoon.

[0030] Step 2. After the silk cocoons are completely dissolved, turn off the heating component 3, wait for the silk protein solution to cool to room temperature, and turn on the rotating separation component 6 to ensure that the solution after the silk cocoons are completely dissolved flows smoothly from the heating reaction chamber 13 to the emulsification reaction chamber 14.

[0031] Step 3. Add emulsifier from the liquid adding pipe 5 and mix it with the silk protein solution in the emulsification reaction chamber 14, turn on the motor 10, and under the action of the motor 10, the stirring rotor 9 rotates at a high speed to fully mix the emulsifier and the silk protein solution, thereby realizing the emulsification process of the silk protein.

[0032] Step 4. Finally, open the drain valve 4 and use a high temperature resistant and corrosion resistant container to collect and store the emulsified silk protein solution for subsequent experiments or production.

[0033] In some embodiments, in order to facilitate the control of the operation of the heating component 3, as shown in FIG. Figure 1 As shown, the heating component 3 is connected to a heating switch 12 , and the heating switch 12 is arranged on the outside of the heating reaction chamber 13 .

[0034] In some embodiments, Figure 1 As shown, the heating component 3 is a heating rod, and the heating rod is provided in plurality and is evenly arranged in an array on the inner wall of the heating reaction chamber 13 .

[0035] In some embodiments, in order to facilitate the operation control of the stirring rotor 9, as shown in FIG. Figure 1 As shown, the motor 10 is connected to a stirring switch 7 , and the stirring switch 7 is arranged outside the emulsification reaction chamber 14 .

[0036] In some embodiments, the silk protein emulsification device used in the laboratory can also achieve more intelligent control. Specifically, Figure 1 and Figure 2 As shown, the silk protein emulsification device used in the laboratory also includes a controller 16, the liquid discharge valve 4 and the valve component are both solenoid valves, and the signal output end of the controller 16 is signal-connected to the signal input end of the liquid discharge valve 4, the valve component, the heating component 3, and the motor 10.

[0037] The controller 16 is an existing component that can be purchased from the market. Considering that the silk protein emulsification device is used in the laboratory, the controller 16 selects a single-chip microcomputer chip, and the connection method between the controller 16 and the discharge valve 4, the valve component, the heating component 3, and the motor 10 adopts a line connection method. Referring to the operation process described above, the controller 16 realizes the control of the discharge valve 4, the valve component, the heating component 3, and the motor 10. For example, after the silk cocoon is cut to remove the silkworm pupa, the silk cocoon after the pupa is put into the heating reaction chamber 13, and an appropriate amount of reaction liquid is added in proportion. After the top cover 1 is covered, the controller 16 is started. The controller 16 controls the heating component 3 to work, and the heating component is closed after the first set time, and then the valve component is opened within the second set time. The first set time and the second set time are predetermined according to the amount of silk cocoons after the pupa are added, wherein the first set time ensures that the silk cocoons after the pupa can be completely dissolved, and the second set time ensures that the dissolved liquid can be reduced to a set temperature (generally room temperature). The valve component is closed for a period of time after the valve component is opened, and the period of time should ensure that the solution after the silk cocoon is completely dissolved flows smoothly from the heating reaction chamber 13 into the emulsification reaction chamber 14. Then, an emulsifier is added from the liquid adding pipe 5. At this time, the controller 16 controls the motor 10 to start. After the set emulsification reaction time, the controller 16 controls the liquid discharge valve 4 to open, and uses a high temperature resistant and corrosion resistant container to collect and store the emulsified silk protein solution at the liquid discharge pipe 8 for subsequent experiments or production.

[0038] In some embodiments, Figure 1 and Figure 3 As shown, the top cover 1 is provided with a temperature measuring hole 2, and a thermometer 17 is installed on the top cover through the temperature measuring hole to collect the temperature signal in the container 15. The signal output end of the thermometer 17 is connected to the signal input end of the controller 16. The thermometer 17 collects the temperature signal of the heating reaction chamber 13 and feeds it to the controller 16 in real time. A temperature threshold is set in advance. The controller 16 controls the heating component 3 according to the temperature signal fed by the thermometer 17, so that the temperature of the heating reaction chamber 13 is always within the set temperature threshold to ensure the heating reaction effect. The control method is: when the temperature signal is at or exceeds the temperature threshold, the heating component 3 is controlled to stop working, and when the temperature signal is lower than the temperature threshold, the heating component 3 is controlled to work. At the same time, after the thermometer 17 is provided, the temperature signal fed by the thermometer 17 can also be used as a condition for opening the valve component. Specifically, after the controller 16 turns off the heating assembly 3 after the first set time, if the temperature signal indicates that the heating reaction chamber 13 drops to a set temperature threshold (such as room temperature), the controller 16 controls the valve component to open and starts the motor 10.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
