Abstract

A dissolution system employs a tapered vessel that has a wide, upper mouth and a narrow, lower neck. A liquid is introduced into the vessel through the lower neck and flows upwardly. A powder to be dissolved in the solution is introduced onto the liquid surface at the wide, upper mouth of the vessel and sinks downwardly into the liquid. Powder that does not quickly dissolve gravitates down towards the neck where dissolution is facilitated by the increased purity and the increased flow per unit area of the incoming liquid. Settling of the powder at the base of the vessel is prevented by the incoming fluid flow. The dissolved solution is withdrawn through an outlet port.
