[0028] The flow limiting device 6 includes a feed hopper 61, a material guide pipe 62, a flow limiting box 63, a transmission motor 64, a flow limiting plate 65, and a flow limiter 66. The feed hopper 61 is arranged at the top of the material guide pipe 62, the material guide pipe 62 is arranged at the top of the flow limiting box 63, and a transmission motor 64 is installed at the front end of the flow limiting box 63. The transmission motor 64 adopts a coupling to drive the front end of the flow limiting plate 65, and the flow limiter 66 is installed at the bottom of the flow limiting box 63. The feed hopper 61 and the material guide pipe 62 are vertically arranged at the top of the flow limiting box 63, and the transmission motor 64 and the flow limiting plate 65 are arranged at the front end of the flow limiting box 63 at the same level, which is conducive to the transmission motor 64 driving the flow limiting plate 65 to rotate.

[0029] refer to Figure 5 , in the embodiment of the utility model:

[0030] The flow limiter 66 includes a flow limiter cover 661, a sealing ring 662, a flow guide pipe 663, a flow limiter cover 664, a flow limiter pipe 665, and a body 666. The top of the body 666 of the flow limiter cover 661 and the bottom of the flow limiter cover 661 are equipped with a sealing ring 662. The flow guide pipe 663 is connected to the bottom of the flow limiter cover 661. The flow limiter cover 664 is fixed to the top of the body 666. The flow limiter pipe 665 is installed at the bottom of the flow limiter cover 664. The flow limiter pipe 665 is fixed to the inside of the body 666. The flow limiter cover 661 and the flow limiter cover 664 are arranged at the same level at the lower end of the inside of the flow limiter box 63. A leak-proof partition is arranged inside the body 666. The flow guide pipe 663 and the flow limiter pipe 665 are arranged in parallel inside the flow limiter box 63. The flow limiter pipe 665 is a spiral structure as a whole, which can well slow down the flow rate of the material.

[0031] refer to Figure 1-Figure 5 When in use, the feed cover 5 is installed on the top of the flow limiting device 6, so that the flow limiting device 6 can play a flow limiting role on the protein stock solution;

[0032] At the same time, pour the protein stock solution from the top of the feed hopper 61 into the guide pipe 62, so that the guide pipe 62 can flow into the interior of the flow limiting box 63, and then adjust according to demand, and start the transmission motor 64 to drive the flow limiting plate 65 to rotate, so that the flow limiting plate 65 can pour the protein stock solution into the interior of the flow restrictor 66;
