This paper describes an experimental investigation of the drying behavior and conditions of rosehip in a convective cyclone-type dryer. Drying experiments were conducted at air inlet temperatures of 50, 60 and 70 o C and air velocities of 0.5, 1 and 1.5 ms. The parametric values obtained from the experiments were fitted to the Newton mathematical models. Consequently, the drying model developed...

This paper proposes an indirect-mode forced convection solar dryer equipped with a PV/T air collector. The collector generates both heated and electrical energy, which are used to force in the dryer. Experiments were carried out on selected tomato slices for temperature humidity readings as well masses of dried samples instantaneously recorded two days. A thermal analysis was performed drying s...

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...

This paper presents the performance evaluation of a passive solar dryer. The Dryer was designed and constructed at Mechanical Engineering Department Caritas University, Amorji-Nike, Enugu, Nigeria. using locally sourced materials from Ogbete main market, Enugu. Experimentation carried out samples 20mm 40mm sliced cassava chips weighing 46g 80g respectively in month November, 2020.Temperature re...

An experimental methodology was developed to improve the energy design of paddle dryers for sewage sludges. A laboratory batch dryer with a vertical agitator has been especially designed and instrumented to determine the heat flux densities. To determine the drying kinetic and the evaporating flow rates, the specific heat and the total heat of desorption of the sludge were measured using calori...

In many industrial applications where compressed air is used it necessary to increase the quality of by decreasing its humidity. This done either a condensation or adsorption dryer in compressor circuit. this article, focus on an dryer. The briefly described together with function and selected range adsorbents suitable for drying. paper further deals development mathematical model humidity whic...
