Definitions

  • Spray drying is a common industrial method for drying liquid solutions or slurries by spraying into a stream of hot gas. It is a rapid, one-step process for converting the feed liquid into a powder. Usually the drying gas is air, but nitrogen can also be used for special products needing oxygen-free conditions.
  • the most common feed materials are aqueous-based solutions, emulsions and suspensions, where water is evaporated in the dryer.
  • the liquid feed is fed to an atomizer, which is a device that breaks up the liquid stream into tiny droplets. This atomization takes place within the drying chamber so that the droplets are immediately exposed to hot air that initiates rapid moisture evaporation. The droplets become small particles of powder as the moisture is evaporated and they fall to the bottom of the drying chamber.
  • Pressure nozzles, rotary disks, two-fluid nozzles, and the like are used as the atomizing unit.
  • the mean particle size (diameter) of the resulting dry powder is about 20 ⁇ m to 500 ⁇ m, and the drying time is as short as 5 to 30 seconds (see, Handbook of Chemistry and Engineering (1999) revised sixth edition, Maruzen Corporation, p. 770, p. 780).
  • a four-fluid nozzle has also been developed, which has enabled mass-scale spray drying with a liquid droplet having a mean particle size of several micrometers.
  • the spray drying method is used in many cases of mass scale production.
  • a solution or slurry is fed at a fast feed rate into a spray dryer, while the inlet temperature of the spray dryer and the outlet temperature thereof are elevated as high as possible, to dry the slurry at a high speed.
  • milk is dried at an inlet temperature of the spray dryer of 150 to 250° C.
  • yeast is dried at the inlet temperature of 300 to 350° C. Drying at such high temperatures may negatively impact the flavor of the raw material itself and produce a dry powder with a burned odor.
  • spray drying at a low temperature to avoid these disadvantages can increase process times and costs. See US 2005/0031769 and U.S. Pat. No. 6,482,433.
  • Spray-dried encapsulated flavors are created during the drying process when the aqueous carrier slurry forms a shell around the normally oil-based flavor core.
  • a thin film of carrier material rapidly forms around the atomized droplet and selectively allows water to evaporate while retaining the flavor oil (Thijssen & Rulkens (1968) De Ingenieur 80:45-56).
  • the shell protects the core against deterioration and volatile evaporation, but also allows the core to be released under desired conditions, for example, dissolution in water.
