Performance of rotating membrane emulsification for o/w production

Controlled production of oil-in-water emulsions containing unrefined pumpkin seed oil using stirred cell membrane emulsification

“…The surface shear can be created by recirculating the continuous phase in cross flow (Figure 1(a)) [1][2], by vibrating [15][16] or rotating the membrane (Figures 1 (b) and (d)) [17][18][19], by vibrating an element (e.g. a wire or plate) in the continuous phase at a short distance from the membrane (Figure 1(c)) [20][21] or by stirring the continuous phase using a stirring bar (Figure 1(f)) [22][23] or a paddle stirrer (Figure 1(e)) [24][25][26].…”

Porous microcapsule formation with microsieve emulsification

“…Since the size of the capsule is important for the rate of release, control over the size and size distribution of microcapsules is a crucial factor. Various studies have been performed on membrane emulsification for production of emulsions, particles and microcapsules [9][10][11][12][13]. We recently investigated conditions for high throughput production of well-controlled oilwater emulsions using cross-flow membrane emulsification with high porosity micro-engineered microsieves [14].…”

Recent advances in the production of controllable multiple emulsions using microfabricated devices

“…3c), tubular vertical membrane moves within a static continuous phase periodically clockwise and counter-clockwise (Silva et al, 2015) or upward and downward (Holdich et al, 2010) with frequencies from 10 to 90 Hz and amplitudes from 0.1 to 7 mm to generate shear on the membrane surface. In rotating (spinning) ME systems, a tubular membrane rotates within a static continuous phase at the speeds ranging from 100-1500 rpm in laboratory systems (Pawlik et al, 2012;Yuan et al, 2009;Vladisavljević et al, 2006a;Aryanti et al, 2006) to 6000-10000 rpm in commercial MEGATRON ® devices (Graber et al, 2010).…”
