Fluid Bed Processor for Snack-Makers
October 4, 2007
Aimed primarily at the healthy-snack market sector, AeroPulse incorporates a patented air system that allows a substantial reduction in the volume of air and energy required to deliver process air to the product. The energy provided by the process air delivery system can be split into two defined components: mechanical energy, which agitates (fluidizes) and separates the product particles, and thermal energy, which provides the product development. The combination of the two energy components results in rapid, uniform heat transfer to the individual product particles, providing excellent final product uniformity. Initially, the rapid heat transfer facilitates expansion of the pellets through changes to their internal structure caused by a sudden increase in internal vapor pressure. After the initial expansion phase, the heat transfer continues and performs two functions: completing the cooking process at the core of the pellet, while also providing final color, flavor and aroma characteristics via the familiar Maillard Reaction.
