Hypothesis
The study aims to model the influential parameters affecting the continuous evaporation of an alcoholic extract using Doehlert matrices.
Conclusion
The study successfully modeled the evaporation process to achieve an 8% dry matter concentrate with optimal productivity.
Supporting Evidence
- The modeling showed weak negative influences of pressure and feed flow, and strong positive effects of temperature and weight fraction on dry matter content.
- Productivity was enhanced by volume flow and dry matter content.
- The model was verified with errors less than 5% after modifications to the evaporation unit.
Takeaway
This study helps us understand how to make a concentrated liquid from plants by controlling temperature and pressure, making it easier to produce valuable products.
Methodology
The study used a wiped falling film evaporator and Doehlert matrices to model the effects of pressure, temperature, feed flow, and dry matter on evaporation.
Limitations
The study faced issues with temperature regulation and measurement errors in dry matter content.
