Integrated design and optimization of a conceptual double drum dryer for drying of wheat flour slurry: Experimental validation and computational analysis

Abstract This study presents a novel conceptual laboratory‐scale double drum dryer (LDD) optimized for the efficient drying of wheat flour slurry into flakes. The research stems from the need to address the complexities of previous methodologies, lack of studies on industrial‐sized dryers, and high cost. The methodology involved designing dryer components, transmission system, creating engineering drawings, and simulating LDD with varied operating parameters. Verification was done using industrial double drum dryer (IGD) data and MATLAB simulations. Parameters were explored including temperature (120–140°C), drum dimension (0.1–0.7 m), and film thickness (0.3–0.6 mm). The design closely matched real‐world performance metrics with mean relative deviations of 2.67%, 3.30%, 10.12% for drum speed, water content, and throughput respectively. The predictive model outperformed the IGD,…
