[0002] Cottonseed is the seed of cotton. The protein content of cottonseed meal after oil extraction from cottonseed kernels is as high as 60%. Cottonseed protein is a high-protein product made by delinting and shelling cottonseed, soaking it in oil at low temperature, draining it, and then removing the toxic substance, gossypol. Cottonseed protein is similar in quality to bean protein, and its nutritional value is far higher than that of cereal protein. During the production of cottonseed protein, how to detect and control the cottonseed protein content is a technical problem that urgently needs to be solved in this field. Existing near-infrared online detection systems can be used to detect the cottonseed protein production process. Online detection can reflect product quality in real time, facilitate content supervision and regulation, and help control the stability of cottonseed protein content. However, existing technologies do not have a mature solution for adjusting the corresponding equipment based on the online detection results to ensure the stability of the product's cottonseed protein content.

[0013] The feed auger 1 is equipped with a spraying device 4, which is connected to a water pump and equipped with a regulating valve. The spraying device 4 is installed under the cover plate of the feed auger 1. A hose with multiple small holes is installed in the gap between the spiral blades inside the feed auger 1 and the cover plate. The programmable controller (PLC) is linked to the start and stop of the water pump based on the detection results of the near-infrared detection system 18 and controls the opening of the regulating valve. When the near-infrared detection system 18 detects that the cotton protein content is higher than the required index, the water pump is turned on, the regulating valve opening is adjusted according to the cotton protein content, and the spraying device is turned on. By adjusting the moisture content, the cotton protein content is kept within a deviation range of +0.2%.

[0014] In this embodiment, multiple stirring wings 12 are welded to the rotating shaft at intervals. These wings 12 are spiral-shaped and each wing is 2-3 cm thick, enabling material transport. The fixed blade 11 is 8-10 cm long and 2-3 cm thick. A screen 13 is installed underneath the mixer 10.
