METHOD FOR PRODUCING A POWDER FROM A LIQUID SUBSTANCE OR MIXTURE OF SUBSTANCES

摘要

According to the inventive method for producing a powder product from a liquid substance or mixture of substances, the liquid substance or mixture of substances to be pulverised is first provided in a pressurised container (10). A gas is then dissolved in the substance or mixture of substances at high pressure. The resulting liquid/gas solution is guided out of the pressurised container to an expansion device (20). The solution is passed through said expansion device where it rapidly expands. A solid powder auxiliary substance is added either before the solution enters the expansion device, whilst it is in said device or afterwards, especially shortly afterwards. In this way a stable, powder product is formed from the substance or mixture of substances.
