Classification of Centrifugal Ventilator 1. Classified according to the pressure (1) Low pressure centrifugal ventilator-windpressure <=980pa (2) Medium pressure centrifugal ventilator-windpressure 980-2942pa (3)High pressure centrifugal ventilator-windpressure 2942-14710pa
There are hard wheat and soft wheat according to horny content. Horny rate of soft wheat is less than 70%, wet gluten content is about 19% ~ 25%. Horny rate of hard wheat is more than 70%, wet gluten content is about 29% ~ 35%. Hard wheat is with higher horny content and much compact endosperm than soft wheat, so it will get a larger extrusion pressure and shear force in milling processing . The main difference of average anti-stress is mainly reflected on whether endosperm become into a powder readily,that is to say,roller clearance of reduction system…
