A system for producing free-flowing powder from liquid solutions or liquid suspensions or liquid dispersions of functional foods, nutraceuticals, and natural health ingredients comprising in combination: (a) a feeding reservoir equipped with an agitator to maintain homogenous liquid compositions of said liquid solutions or liquid suspensions or liquid dispersions; (b) a positive displacement pumping device to pump said liquid composition into at least one atomizing device; (c) said at least one atomizing device composed of: (i) at least one fluid nozzle fitted at its bottom with a body in the shape of a truncated cone to distribute an upward gaseous drying medium over said nozzle; (ii) a optional micrometric tool to vertically adjust the position of the said fluid nozzle; (iii) a first streamlined tube-like device for directing said liquid solutions, liquid suspensions or liquid dispersions to the nozzle in a first direction and a second streamlined tube-like device for directing compressed air to the nozzle in a second direction opposite to the first direction; (iv) a cylindrical plenum chamber wherein the fluid nozzle is located; (v) a cylindrical pipe located at the bottom of the cylindrical plenum and having a length equivalent to at least five times the diameter of the inlet of the said cylindrical plenum chamber; (d) a conical-cylindrical drying chamber (60, 70) adapted to sustain a temperature of gaseous drying medium at 250°C and above equipped with a manhole, a multi-nozzle manifold and optionally removable insulation panels; (e) an intermediate drying medium consisting of a single bed or multi-beds of inert carriers leading to reduced volume of the drying chamber. (a) a feeding reservoir equipped with an agitator to maintain homogenous liquid compositions of said liquid solutions or liquid suspensions or liquid dispersions; (b) a positive displacement pumping device to pump said liquid composition into at least one atomizing device; (c) said at least one atomizing device composed of: (i) at least one fluid nozzle fitted at its bottom with a body in the shape of a truncated cone to distribute an upward gaseous drying medium over said nozzle; (ii) a optional micrometric tool to vertically adjust the position of the said fluid nozzle; (iii) a first streamlined tube-like device for directing said liquid solutions, liquid suspensions or liquid dispersions to the nozzle in a first direction and a second streamlined tube-like device for directing compressed air to the nozzle in a second direction opposite to the first direction; (iv) a cylindrical plenum chamber wherein the fluid nozzle is located; (v) a cylindrical pipe located at the bottom of the cylindrical plenum and having a length equivalent to at least five times the diameter of the inlet of the said cylindrical plenum chamber; (i) at least one fluid nozzle fitted at its bottom with a body in the shape of a truncated cone to distribute an upward gaseous drying medium over said nozzle; (ii) a optional micrometric tool to vertically adjust the position of the said fluid nozzle; (iii) a first streamlined tube-like device for directing said liquid solutions, liquid suspensions or liquid dispersions to the nozzle in a first direction and a second streamlined tube-like device for directing compressed air to the nozzle in a second direction opposite to the first direction; (iv) a cylindrical plenum chamber wherein the fluid nozzle is located; (v) a cylindrical pipe located at the bottom of the cylindrical plenum and having a length equivalent to at least five times the diameter of the inlet of the said cylindrical plenum chamber; (d) a conical-cylindrical drying chamber (60, 70) adapted to sustain a temperature of gaseous drying medium at 250°C and above equipped with a manhole, a multi-nozzle manifold and optionally removable insulation panels; (e) an intermediate drying medium consisting of a single bed or multi-beds of inert carriers leading to reduced volume of the drying chamber.
