from first process of purification and he sorts of a blend of vegetable origin represents it the aerodynamic separation, which operation is caned realize in combination or don't with another method is separated. The behavior of a particle air flow is accessible to next features: form and the sizes particles, the density and the humidity particles and the state surface particles. Caned achieved an aerodynamic separation is due to is known the speed of floats what particles is submissive processes. Speed of float of a real particle, particle obtained from agriculture or from breaching up operation with form and the variables sizes, caused with of help special equipment.
