Solar drying is one of the many ways efficiently making use solar energy to meet human demand for improved sustainability. In this study, we describe construction and testing two indirect dryer prototypes, especially designed vegetables fruits. The dryers had compartments: a panel chamber. were mainly made wood (Prototype 1) styrofoam 2) both used recycled aluminum cans. calculated yield panels...

South East Queensland is one of the fastest growing regions in Australia with a correspondingly rapid increase in sewage production. In response, local councils are investing in more effective and sustainable options for the treatment and reuse of domestic and industrial effluents. A novel, evaporative solar dryer system has been installed on the Sunshine Coast to convert sewage sludge into a d...

Two identical prototype solar dryers (direct and indirect) having the same dimensions were used to dry whole mint. Both prototypes were operated under natural and forced convection modes. In the case of the later one the ambient air was entered the dryer with the velocity of 4.2 m s(-1). The effect of flow mode and the type of solar dryers on the drying kinetics of whole mint were investigated....

In this paper, the modelling and control of the moisture content of the particles in a batch Fluidised bed dryer are studied. First, a lumped mechanistic model is developed to describe the heat and mass transfer between solid, gas and bubble phases and experimental validation shows that the model can be used to predict the particle moisture content and temperature profiles during the drying pro...

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...

ABSTRACT Increasing the efficiency of solar dryers with ensuring that system remains accessible to all users can be achieved their automation through low-cost and easy-to-use technique sensors. The objective was develop, implement evaluate an automatic for monitoring drying parameters in a hybrid solar-electric dryer (HSED). Initially, automated data acquisition collecting sample mass, air temp...

Technological and economic developments are directly proportional to the industrial sector, especially in countries that still developing. The food industry is one of them. Chocolate growing foods industri. research on Comparison Drying Rate Cocoa Beans Using a Dryer with Electricity Solar Energy was carried out using an experimental method, namely electricity coming from solar panels then PLN....

In this paper, a cascade control strategy is applied to the temperature inside hybrid solar-gas dryer. order use dryer even at night and in unfavorable weather conditions, drying chamber heated by two systems. The first one solar air heater second gas heater. collector relatively slow compared heating system. Static dynamic studies were established have revealed nonlinear behavior of each subsy...

Abstract One of the stages processing green bananas into flour is drying process. The kinetics this process needs to be studied as a step in optimizing and improving performance. This study aimed assess various models that could explain banana slices specify parameters slices. house effect (GHE) solar dryer was used for drying. data were fitted (Page, Newton, Henderson Pabis, Verma, Logarithmic...
