In this study, the effect of some processing parameters on bulk density, particle density, particle size and some of powder reconstruction properties such as dispersibility, Wettability and water solubility index of spray dried barberry (Berberis vulgaris) juice powders were investigated. A Pilot Spray Dryer (Two- Flow nozzle, counter- current, one cyclone) was employed for the spray d...

In this paper, a flexible method of optimizing the velocity plunger is presented by selecting important oil well production parameters through orthogonal test and combining structural pump barrel. order to explore influence motion rate optimized on efficiency, law curves before after optimization were compared, efficiency was theoretically analyzed. The flow simulated model. Finally, pumping un...
Optimization of fed-batch feeding parameters was explored for a system with multiple mechanisms of product inactivation. In particular, two separate mechanisms of inactivation were identified for the recombinant tissue-type activator (r-tPA) protein. Dynamic inactivation models were written to describe particular r-tPA glycoform inactivation in the presence and absence of free-glucose. A glucos...
A model of a mixed-mode nutrient recovery reactor is developed for a urine feed, incorporating complex solution thermodynamics, dynamic conservation relations and a power-law kinetic expression for crystal growth from seed crystals. Simulations at nominal operating conditions predict phosphorus recoveries greater than 99%, based on existing process kinetic parameters and operating conditions em...
This study aims to optimize extraction and drying conditions of fig syrup. Drying was done in a pilot scale two-fluid nozzle spray dryer. A total of 27 experiments were conducted with varying inlet air temperatures, air flow rates, and also a maltodextrin (MD)- low methoxyl pectin (LMP) ratios. While feed rate, feed temperature, and compressed air flow rate of the atomizer were kept constant. T...
The purpose of this study was to determine the lactose behaviour during partial crystallisation in spray drying. Spray-dried lactose has been widely used in pharmaceutical industries as excipient for dry powder inhalation drugs. Partial crystals of lactose were produced by spray-dried lactose solutions at different operating condition of inlet temperature, feed flow rate and sample concentratio...
Simultaneous removal of NO(x) and SO2 from exhausted gas were investigated by studying co-culture of sulfate reducing bacteria and anaerobic denitrifying bacteria, separated from landfill leachate. When H2S, generated by sulfate reducing bacteria was chosen as the sole electron donor for anaerobic denitrifying bacteria, the co-culture system demonstrated a faster NO removal rate, higher stabili...
