Recently, as interest in safe food and ingredient content has increased, the demand for highly concentrated health functional food that can be manufactured at home is increasing. Accordingly, in this study, we developed a galenic maker that can increase the extraction efficiency of herbal medicine(ginseng) ingredients and shorten the manufacturing time. After verifying the safety of the designed components through structural analysis and thermal flow analysis, the dimensions and shape of the galenic maker were determined. A prototype was produced based on the design process and the performance of the product was verified through extraction efficiency and ingredient analysis.

Water resources are the most important resources for all living things on the earth to grow and reproduce, and sustain agricultural, industrial, household, recreational and environmental activities. Since 97% of these water resources is a seawater, desalination is a practical choice of many water-poor countries. Currently MSF (multistage flash evaporation) and RO (reverse osmosis) that need 25 kWh and 4kWh per m3 of fresh water although thermal methods need 718kWh and pressure based-RO 1kWh. This work focuses on how to estimate highest osmotic pressure of many aqueous saturated solutions such as NaCl and fuel ethanol that reaches 343.07 bars of 26.47%, over 5000 bars, respectively. This work shows that Lewis equation (1908) fits within 10% of OLI pressure and the modified estimation of Chang (1983) within 1% accuracy.

Membrane filtration has been considered as an promising harvesting technology in the fields of microalgal biorefinery to produce biofuels and valuable chemicals from microalgal biomass. For developing the effective membrane-based harvesting process to produce highly concentrated biomass, membrane fouling should be controlled because it leads to not only reduced filtration rate but also insufficient reachable concentration of harvested biomass for downstream process. For that, a dynamic filtration using a rotating disk was evaluated in this study, efficiently generating high shear flow near the membrane surface by an independently moving part. It was demonstrated to achieve feasible filtration performance even under high biomass concentration with complete biomass recovery and moderate energy consumption observed.
