Embodiment 1
[0063] Embodiment one: the preparation of high-protein cotton meal
[0064] See attached figure 1 , the present invention provides a kind of preparation method of high-protein cotton meal, % is calculated by weight ratio w / w (kg / kg), and specific preparation method is as follows:
[0065] (1) Cottonseed delint and impurity removal: After the cottonseed has been processed to remove impurities and delint, the impurity content is less than 0.5%, and the cashmere content is less than 4%.
[0066] (2) Cottonseed peeling: The cleaned and removed cottonseed is evenly fed into the shelling roller through the frequency conversion feeding device, and the tooth angle of the first set of toothed rollers of the shelling roller is 40°-85°. The angle is the angle between the horizontal line and the inclined line, and the adjustment gap is 2.4-2.8mm; the tooth angle of the second set of toothed rollers is 35°-70°, the tooth angle is the angle between the horizontal line and the inclined lin...
