A process for degerminating corn kernels, comprising, in the sequence indicated: a first tempering step; a polishing step by effectively rubbing said bran to shear said bran from said endosperm; a second tempering step; and a friction step wherein said friction step comprises applying friction forces to said corn kernels between at least two elastic surfaces.
WhatsApp: +86 18838072829Jet mills use no moving parts to apply force, generate no heat, and process material in a single pass. Jet mills use highpressure (approximately 50120 psig), turbulent condensed air (or other gases) to force highvelocity collisions between mill feed particles in a onestep milling process, inside a chamber. The mill's power can be adjusted to
WhatsApp: +86 18838072829In metal shearing machines, the blades can be mounted at an angle to reduce the amount of shearing force required to produce the cutoff. Perhaps the biggest advantage of shearing is that it produces minimal or no kerf, with virtually no loss of material. For an application such as shearing a rod, the typical tolerance is ± ( mm).

WhatsApp: +86 18838072829Hole punching is a shearing process that is used to create holes in material sheet and plate. Hole punching uses hardened tools with sharp edges and an applied force to shear out the unwanted material. The force applied can be electrical, hydraulic, pneumatic, or even manual. The hole punching tools can be a variety of shapes. What is Notching?

WhatsApp: +86 18838072829This paper presents an instantaneous cutting force prediction model for a disc mill cutter with indexable inserts. Cutting characteristics, including the normal friction angles, normal shear angles, and shear stress, are decisive factors in determining the instantaneous cutting force coefficients. The cutting characteristics can be determined by several specialized milling experiments, instead ...

WhatsApp: +86 18838072829Shear forces are best applied to relatively soft materials, again including fibrous foods. All three types of force are generated in most types of mill, but generally one predominates. For example, in most roller mills compression is the dominant force, impact forces feature strongly in hammer mills and shear forces are dominant in disc attrition
