Abstract
An improved method and apparatus is disclosed for producing frozen particulate compositions from liquid feedstock. A continuous stream of liquid feedstock is passed through an orifice and into a liquid freezant without the orifice contacting the freezant. Compositions produced by this improved method have low proportions of fine and large particles, yielding particularly beneficial results in the case of quality control materials. The compositions are advantageously employed in automated weighing and filling apparatus.
