Powder fat enrichment comprises feeding solid particles into a mixing container, separating them using a mixing tool, spraying hot fat onto the solid particles, and heating

摘要

A process for enriching powders with fat or similar components, comprises fluidizing powder using a mechanical mixer. Hot fat is sprayed onto the solid particles (2) from a nozzle in droplet form. The fat aerosol produced is heated to a temperature at which the droplets are still sufficiently fluid when the fat penetrates the solid particles. A process for enriching powders with fat or similar components, comprises fluidizing powder using a mechanical mixer. The solid particles (2) are fed into the mixing container (1) and separated by a mixing tool (3) so the contact between solid particles is less in a predetermined fluid area than in the rest of the container. Hot fat is sprayed onto the solid particles from a nozzle in droplet form. The fat aerosol produced is heated to a temperature at which the droplets are still sufficiently fluid when the fat penetrates the solid particles. The average volume of the droplets is at least three times smaller than the average particle volume.
