Abstract: This invention relates to micro-encapsulated particles of solid matter and a quasi-continuous method for producing the same, especially those having water-insoluble characteristics or a hydrophobic form, taking into careful consideration ecologically and economically favorable ways of recycling the media used, and the resulting smallest possible amount of waste products such as waste water and polymer residues, while simultaneously ensuring that even exposed parts of the solid bodies are coated, such as crystal tips and grooves, which are insufficiently coated using standard methods due to the hydrodynamic conditions on these areas.
