Low Temperature Microfiltration of Skim Milk: Impact of Membrane Type, Configuration and Concentration Factor on Serum Protein Permeation Efficiency
Social Science Research Network(2022)
摘要
Protein transmission, permeate flux and energy consumption during MF of skim milk was evaluated at 7 °C using two discrete 800 kDa polymeric MF membranes. Filtration trials determined optimum process parameters (i.e., transmembrane pressure and volume concentration factor) and membrane configuration (in-series or in-parallel) to maximise serum protein permeation. This study demonstrated that a combination of higher VCF (3) and lower TMP (75 kPa), with an in-parallel membrane configuration resulted in the most efficient rate of permeation of serum protein per kg of permeate produced. However, from an energy perspective, an in-parallel configuration with a TMP of 75 kPa and a lower VCF2 was the most efficient process, consuming between 1.28 and 1.57 kW h kg−1 of crude protein permeated. Additionally, the permeation of serum β-casein at low temperature was governed by the uniformity of the pore size distribution in discrete MF membranes with the same nominal molecular mass cut-off.
