| Abstract | |
This work involves the simulation of scale-up and economic evaluation of the production process of passion fruit leaf extract (Passiflora edulis Sims) through intermittent pressurized liquid extraction. The highest extraction efficiency was achieved using a 70 % ethanol (v/v) mixture on a laboratory scale at 80 degrees C with 100 % solvent renewal per static cycle in 5 cycles and 6 min of static time. A scale-up study was conducted, keeping both the significant process variables and the solvent mass/feed mass ratio constant at (S/F= 4.25). This scale-up method proved effective for scaling from laboratory to pilot scale (from 34 mL to 2 L). Extraction with the pilot-scale equipment yielded total solids ranging from 35.6 +/- 1.5 % with a consumption of around 3768.4 +/- 121.3 mL of solution. The extraction curves were similar for both scales despite different times. Manufacturing Cost (COM), Profitability Analysis, Return on Investment Rate, Gross Margin, and Payback Time were simulated using SuperPro Designer (R) version 8.5 software. Five extraction systems were evaluated, with four using 2 extraction cells in a semi-continuous system with capacities of 2, 10, 50, and 100 liters and one in a batch system with only 1 cell. The results demonstrated that industrial-scale equipment has a lower COM if operated in a semi-continuous regime (2 extraction cells) with just two extraction cycles, presenting a competitive market price.
