Numerical optimization of guaco leaves extraction based on pre‐heat treatment

The mass yield of the extraction is influenced directly by pre-treatment conditions raw material. In case leaves, drying required to ensure their biological stability and a pre-processing step that demands large amounts thermal energy. present study, oil process was numerically optimized, considering influence pre-heat treatment guaco leaves. An operating range between 30°C 70°C, 1.0 5.0 m/s, recirculation 0 1 evaluated. minimum ratio energy consumption amount obtained after (4.05 × 105 kWh/kg) under optimal 30.02°C, .129 air recycling flow rate. With our results, it possible guarantee safety in storage addition optimizing process, maximizing obtaining mass, reducing step. Practical applications Tea one most consumed beverages world extraction. Between tea (Mikania glomerata Sprengel) mainly applied obtain therapeutic properties as an expectorant bronchodilator. While leaves are perishable, they must be dried stability. As others heat transfer processes, efficient design mandatory reduce consumption. One more processes operation exhaust recirculation. Thus, there need evaluate understand effects on extract Our numerical results indicated storing optimize its process.
