Prior to developing this strategy, the interplay of the independent variables for a spray-dry process was taken into consideration, specifically how and which parameters were affecting the yield and the particle size ().Particle size is a key attribute of amorphous solid dispersions and affects the final performance of the material (e.g., …

Moreover, it influences the droplet size of the spray, which in its turn influences the drying kinetics and final particle size. A higher nozzle pressure …

1. Introduction. Spray drying is a well-known method of particle production which consists on the transformation of a fluid material into dried particles, taking advantage of a gaseous hot drying medium [].Its first observation is dated 1860 and a primitive spray dryer device was patented by Percy in United States in 1872 [1, …

Spray drying is used in the pharmaceutical industry for particle engineering of amorphous solid dispersions (ASDs). The particle size of the spray-dried (SD) powders is one of their key attributes due to …

Despite a relatively small particle size range in the spray-drying system (Table 2), the XRPD, Raman and FT-NIR results showed that the polymorphic form of mannitol changed as a function of particle size with varying behavior observed in all the four spray-dried systems. 4.2.1.

Following a factorial experimental design, a series of spray drying experiments were conducted to gain new insights into the influences of the inlet temperature, the spray solvent, and the solute concentration in the spray solution on the yield, the moisture content, and the particle size of the nano spray-dried powder material.

John Baumann is the Director of Spray-Dried Particle Engineering at Bend Research, where he has worked since 2004.Mr. Baumann manages a spray-drying process-development group focused on the preparation of pharmaceutical intermediates and the scale-up and transfer of spray-drying processes from research laboratories to …

Spray drying is a powerful particle engineering tool, by altering the different spray drying processing parameters, it is possible to control the properties of the resultant particle including size, shape and density. …

The physical properties of the final product, such as particle size, density and morphology, can be altered by changing the process and formulation conditions. 2.2.2. Spray Dryer Setup . Atomization is a critical step in the spray drying process because the particle size, morphology, and residence time of the droplets/particles in the drying ...

Occasionally, the second stage of a two stage dryer is used to agglomerate product particles. Since the particles leaving the first stage are still sticky, they will bond with other particles during the second stage drying. Some installations spray wet particles from the first stage with additional feed in the second stage.

The control strategy is required to be sufficiently flexible to control the particle size of a range of formulations on a pilot plant scale mixed flow spray dryer. 2 Materials and methods The pilot plant scale …

Particle size of the spray dried powder. The mean particle size of spray dried powder was determined by laser light scattering technique in Mastersizer 3000 with Aero S dry powder disperser (Malvern Instruments, Malvern, UK). Each sample was measured in triplicate. 2.4.3. Moisture content and hygroscopicity

Spray drying (SD) is a simple and attractive route to granulate particles with controlled morphology, size and density. SD is capable to produce different particle morphologies such as hollow, donut and spherical shapes with high production yield.

Hence, a full 3D model of a pilot plant spray dryer (1.2 m diameter, 2.85 m height) was developed using COMSOL Multiphysics ®. The air flow pattern in the drying chamber was modelled using CFD and the RTD for different particle size fractions was obtained using the Particle Tracing Module with a particle counter at the dryer outlet.

The effect of the three spray-drying process parameters on particle size distribution depended on the drying nature of the materials. The three parameters interacted to significantly affect particle size of CNC suspensions, whereas they did not interact to affect particle size of NFC suspensions.

Particle size was inversely related to specific surface area and the amount of protein aggregates formed. Zinc-complexation reduced the specific surface area and stabilized the protein against aggregation. FTIR data indicated perturbations in secondary structure upon spray-freeze drying for both excipient-free and zinc-complexed protein.
