CASCADE VERTICAL DRYING

摘要

Identified trends in drying requirements define a dryer capable of high volumernprocessing for a wide range of product sizes and shapes, greatly improved sanitation,rnincreased moisture uniformity control, energy efficiency and simplified mechanicalrndesign. This dryer must utilize less plant floor area; while being competitively pricedrnwith today's less efficient conveyor style dryers.rnThe Cascade Dryer is a vertically configured, multi-stage, continuous batch,rnconvection dryer, designed to meet the rigorous future requirements dictated by therncommercial marketplace. A vertical dryer utilizes gravity to move product throughrnheated airstreams, eliminating mechanically complex conveyor systems. Verticalrnconfiguration exchanges floor area space requirements for less costly plant heightrnvolume.rnThis paper presents pertinent drying theory and its application to modern dryerrndesign, product and air flow details and performance data from actual Cascade Dryerrnoperations.
