“…A three-phase flow solution using the Eulerian-Lagrangian approach was used to estimate particle tracking the spray dryer in this work. The continuous phase in this approach is air, while the discrete phase is particles [16]. The gas phase was analyzed using the Eulerian approach by solving the Navier-Stokes equation, and the particle movement was simulated using Lagrangian path analysis.…”

“…Many experimental and numerical research have been conducted to investigate the properties of the spray drying process. CFD analyses showed good predictions of the temperature and velocity distributions in the spray dryer compared to the experimental approach [1,[16][17][18][19].…”

“…The k-ω SST turbulence model provides more accurate rotating flow modelling results than the k-ε turbulence model [26,27]. However, the standard k-ε turbulence model can produce more accurate fluid flow characteristics at the spray dryer wall compared to realizable k-ε and RNG k-ε turbulence models [1,16,28,29]. It has also been shown that while Reynolds Stress Model (RSM) turbulence model can provide more accurate results, the k-ω SST and the standard k-ε has a much lower computational time [17,30,31].…”

This study aimed to analyze the effect of inlet temperature and airflow direction variation of a spray dryer on the product’s water content and minimum droplet temperature using the means of computational fluid dynamics (CFD). The airflow direction types were mixed and co-current. To simulate the flow, the k-ω SST and standard k-ε models were utilized, and the Eulerian-Lagrangian approach was used to estimate particle motion. The simulation results showed that water content reduced as temperature climbed for both airflow directions and vice versa for the minimum droplet temperature. With droplets diameters of 10 μm and 30 μm and an inlet temperature of 180°C, both mixed flow and co-current flow spray dryer generated the lowest water content (0%) output. The lowest minimum droplet temperature (32.73°C) occurred in the mixed flow spray dryer with an inlet temperature of 100°C.

“…Another spray drying experiment was conducted by varying drying temperature from 140 to 200 °C while maintaining the drying air flow rate (7.5 m 3 /min), emulsion feed rate (0.0003 kg/s) and atomization pressure (0.52 MPa) constant (Habtegebriel et al 2019). Camel milk powder had a moisture content of 7.04% [w/w] at lower temperature (140 °C) and 2.7% [w/w] at higher temperature (200 °C).…”

Camel milk is the mainstay for millions of people in arid and semi-arid environments. In these areas, it is mainly consumed raw or after it spontaneously turns sour. Although some attempts have been made to produce dairy products from camel milk, processing of camel milk is generally considered to be difficult and the quality of the final products made from camel milk do not correspond to their bovine milk counterparts. This paper reports a comprehensive analysis of the literature on camel milk products and presents synthesis of the latest developments, limitations pertaining processing and opportunities for development of new and improved camel milk products. The protein composition and colloidal structure of camel milk differs from cow milk. It is characterized by absence of β-lactoglobulin, low κ-casein content, high proportion of β-casein, larger casein micelles and smaller fat globules. These differences lead to the difficulty of making dairy products from camel milk using the same technologies as for bovine milk. Some of the challenges of camel milk processing include poor stability of the milk during UHT treatment, impaired rennetability, formation of weak and fragile curd during coagulation, longer fermentation time, and low thermal stability of the milk during drying. Despite these difficulties, it has now become possible to produce a range of commercial and traditional dairy products from camel milk. Some of the strategies that could be applied to improve the quality and characteristics of camel milk products are discussed. Graphical Abstract
