The pressure applied to the homogenizer 10 may be 500 to 80,000 psi, but may be suitably adjusted according to the product to which it is applied. The raw material to be pulverized can be pulverized to a predetermined size by cavitation, turbulence or shear force while passing through a homogeneous unit formed of, for example, a nanocell made of diamond material. Depending on the type of raw material, the pressure applied to the appropriate nanocells and homogeneous units can be determined.

In addition, the input speed can be adjusted according to the information transmitted from the detection unit provided in the processing module 14. [ The raw material can be supplied from the storage unit such as, for example, the raw material supply tank 13a to the input module 13 through the supply line SL.
