Food Engineering: Lesson 43. SIZE REDUCTION

Size reduction of solids involves creating smaller mass units from larger mass units of the same material. To bring this about, the larger mass units need to be subjected to stress by the application of force. Three types of force may be applied, i.e. compression, impact and shear. Compressive forces are generally used for the coarse crushing ...
