Expansion chamber AeroExpander™

AeroExpander™ Hot Air Expansion for Snack Pellets Continuous hot air expansion for healthy snack foods. Bühler’s AeroExpander is an innovative solution applied in the processing of snack food pellets and third generation snacks. Using hot air instead of oil for expansion, snack food processors are able to reduce cost while providing a healthier snack alternative. AeroExpander employs air circulation and variable temperature control with a custom conveying system to ensure precise dwell time and product uniformity. This control benefits customers by boosting productivity and maintaining consistent quality in the demanding snack food market. Unique heat transfer and product tracking ensure high-quality expansion. The AeroExpander expands the pelleted snack product during a continuous conveying process. The unit provides a high rate of thermal transfer and precise control of expansion, bulk density, color and texture. A specialized air delivery system with dual plenum design means expansion of 100% of the product is achievable. The compartmentalized conveyor bed offers first-in/first out product tracking for consistent and efficiently controlled expansion.
