FLUIDIZED BED PROCESS FOR MAKING BEVERAGE, FOOD OR THE LIKE

摘要

Absorption drying provides a means for agglomerating dried food and beverage solids around an aroma/flavor core, thereby essentially encapsulating said core and pre serving volatile flavor and aroma compounds. The absorption drying process is especially useful for manufacturing instant coffee. Thus, a viscous liquid extract comprising coffee aromas and flavors is sprayed into a fluidized bed of instant coffee powder. Encapsulation of the coffee extract occurs as multiple particles of the coffee powder attach themselves to the aroma/flavor droplets to form aggregates. Rapidly drying the aggregates preserves the aroma/flavor in the core of the aggregates until released during use.
