Papaya is a rich source of nutrients, antioxidants, and vitamins; however, it highly perishable hence needs to be preserved using suitable unit operations. Drying an economical method papaya treatment, but results in the loss essential nutrients also degrades its pigments, color, texture. Therefore, this work aims utilize ultrasound osmotic dehydration as pretreatment strategies preserve compos...

Drying represents one of the oldest unit operations employed in industrial processes. Drying is viewed as a process of simultaneous heat and mass transfer. Porous Clay-like material undergoes stresses due to non-uniform distribution of temperature and moisture induced by heat and mass transfer respectively. The aim of this work is to simulate the stresses induced by heat and mass transfer durin...

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 ...

Analytical solutions of the diffusion and conduction equations applied to liquidside-controlled convective drying of a multicomponent liquid film are developed. Assuming constant physical properties of the liquid, the equations describing interactive mass transfer are decoupled by a similarity transformation and solved simultaneously with conduction equation by the method of variable separation...

Solar drying and convective oven of cherry tomatoes (Solanum lycopersicum) were compared. The changes in the chemical parameters principal recorded during process. Drying curves fitted to several mathematical models, effects air temperature evaluated by multiple regression analyses, comparing previously reported models. Models for conditions indicated a final water content 30% (semidry products...

The factors that control the influence of deep convective detrainment on water vapor in the tropical upper troposphere are examined using observations from multiple satellites in conjunction with a trajectory model. Deep convection is confirmed to act primarily as a moisture source to the upper troposphere, modulated by the ambient relative humidity (RH). Convective detrainment provides strong ...

Continuous convective-sedimentation assembly (CCSA) is a deposition method that constantly supplies the coating suspension to the meniscus behind the coating knife by inline injection, allowing for steady-state deposition of ordered colloids (which may include particles or cells or live cell-particle blends) by water evaporation. The constant inflow of suspended particles available for transpor...
