摘要： This disclosure relates to process for producing titanium dioxide (TiO2) pigments, comprising the following steps: a) oxidizing a mixture of titanium tetrahalide and a rutile forming agent, such as aluminum halide, present in the vapor phase and in the presence of a nucleant to form a gaseous suspension comprising titanium dioxide particles; b) passing the gaseous suspension to a cooling conduit; c) introducing scouring material into the cooling conduit; wherein the particles of the scouring material have a diameter in the range of about 0.25 mm to about 12.7 mm; d) separating the vapor phase to form a powder comprising the titanium dioxide particles and the scouring material; and e) simultaneously subjecting the powder to substantially uniform heating at a temperature of about 300° C. to about 600° C. and reducing the size of the titanium dioxide particles and the particles of the scouring material in the powder to a mean particle size of about 50 nm to about 1000 nm, whereby the titanium dioxide pigment has a chloride content of less than about 500 ppm. The so treated powder may have a residual free chlorine content of less than about 1 ppm.

摘要： A process for dry coating a food particle having a size in the range from about 0.5 mm to about 20.0 mm is disclosed. The resulting coated food particle has a moisture level that is substantially the same as the moisture level of the uncoated food particle. A process for encapsulating a frozen liquid particle having a size in the range from 5 micrometers to 5 millimeters with a liquid coating material is also disclosed. Also disclosed are coated food particles and encapsulate frozen liquid particles made by one of the processes of the invention.

摘要： An apparatus and process for uniformly mixing a relatively small amount of material with a relatively large amount of another material in particulate form by introducing the smaller amount of material via a pipe within another concentric pipe through which a high pressure gas is introduced which thereby provides a zone of turbulence into which a particulate material in larger amounts is introduced, the mixture of gas and materials being transported through a treatment chamber to produce a uniform mixture.
