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 effects of excipient crystallinity and water content on the physical stability of salmon calcitonin (sCT) in a spray-dried powder for inhalation have been investigated. sCT was dissolved in water with and without mannitol and then spray dried using a Büchi 190 spray dryer. The spray dried powders were stored for 5 days at 0, 29, 51, 58, 69, and 84% relative humidity at ambient temperature. ...

This research presents an experimental analysis of a counter flow spray drying process using water and skim milk as feed. The study was performed by examining the droplet size distribution sprays temperature profiles in dryer. influence air inlet temperature, mass rate, feed on temperatures dryer evaluated. evaporation deposition zones were found to be highly dependent size. obtained results sh...

A mathematical model for the evaporation of a single droplet, subjected to convective drying in a spray dryer was developed to study the transient phenomena of particle formation. During the constant-rate drying period, the governing equations and boundary conditions were transformed into a form containing Peclet number, Pe, as the main controlling parameter. A numerical solution was developed ...

This study was to utilize the waste from canned tuna processing (tuna precooking juice) for producing dried tuna flavor powder. Tuna precooking juice was centrifuged and concentrated to 15% total soluble solid (TSS). Maltodextrin (DE 9) was added to increase the TSS of tuna precooking concentrate to 20, 22, 24 and 26%, then dried by spray dryer at 180oC inlet air temperature. The compositions a...

The aim of this work was to study the effect of spray drying conditions on quality of coconut sugar powder and their characteristics. Effects of inlet air temperature (120°C, 150°C and 180°C) and maltodextrin concentrations (DE 9-12) at 10%, 20% and 30% (w/v) on physical properties of spray dried coconut sugar powder were investigated. Buchi mini spray dryer, model B-290, was used in this work....

The current work investigates the performance of a single-stage, bench-scale system using a spray dryer to treat produced water. The produced water is generated in three large reservoirs of Ahvaz, Maroon, and Mansouri fields, which have different compositions but the same high total dissolved solids (TDS) and total organic carbon (TOC). The results of this study indicate that the newly develope...
