Method for extracting e.g. natural active ingredients from products in e.g. analytical chemistry field, involves recovering active/ trapped constituents between sieves per aspiration and by fall of particles under effect of gravity

摘要

The method involves pulverizing (E2) individualizing components of a dry product in the form of micro/nanoparticles. A dust cloud is obtained (E3) from micro or nanoparticles. The micro/nanoparticles are separated (E4) from the dust cloud according to its granulometric size. Active/ trapped constituents are progressively recovered (E5) between two sieves per aspiration, centrifugation or by fall of the particles under the effect of gravity.
