Jet-milling apparatus and method for jet-milling

A jet milling apparatus, comprising:

• a milling chamber having at least one inlet for a product to be milled and one or more outlets for a milled end product having physical properties with respective values falling inside respective ranges;
• one or more nozzles for issuing respective jets of a milling fluid having predetermined operative parameters into said milling chamber for intercepting the product to be milled and forming a fluidized material inside said milling chamber for drying, selecting, milling, sterilizing, clustering the product;
• one or more electromagnetic field emitters placed at said milling chamber and designed to generate an electromagnetic field with predetermined frequencies and to orient it inside said milling chamber;
• monitoring devices placed at each of said one or more outlets for controlling in real time the physical properties of the milled end product before exit from said milling chamber;
• wherein said monitoring devices are designed to drive at least said one or more nozzles and said electromagnetic field emitters to vary and adjust the operative parameters of the jets of the milling fluid and the frequency of the electromagnetic field in such a way that combined action of drying, milling, clustering of the product to be milled occur.
