The main aim of this study was to design and develop hybrid dryer in which heat sources are coming from coffee husks furnace and solar collectors used for coffee beans drying. We also tested its performance and calculated the energy consumption produced and total costs required to perform coffee beans drying. The study consisted of three stages; (1) structural and functional design of drying chamber, furnace and solar collector, (2) dryer construction and development, (3) functional test. The overall results of this study showed that solar collector was effectively working properly during the ten days drying. Yet, this developed dryer is still heavily influenced by the weather, and thus the use of biomass as an energy supplement is needed. The average air temperature produced by the dryer ranges between 36.2 oC to 48.6 oC, while the relative humidity (RH) ranging from 43.6% -72.6%.

Abstract

Biodiesel is one among the promising renewable fuels, holding various advantages compared with fossil fuel. In this study, reactive extraction of jatropha seed for biodiesel production was investigated. The effect of moisture content of jatropha seeds and cosolvent concentration was examined to determine the best performance of the biodiesel production yield. The co-solvent used is hexane. Design of experiments (DOE) was used to study the effect of moisture content of jatropha seed and co-solvent of hexane concentration on the yield of biodiesel. Generally, the moisture content of jatropha seeds and co-solvent concentration affected biodiesel production yield. The experimental result also shows that the transesterification rate was improved when compared to the system without co-solvents. It was found that the production of biodiesel achieved an optimum level of 68.3% biodiesel yield at the following reaction conditions, i.e. moisture content of jatropha seed of 1% and hexane to oil ratio of 6.9 (w/w).

Abstract

As the availability of high quality trees decreased and the price increased the wood base panel industry is looking to replace the common used wood by agricultural residues or fast growing trees and plants as well as agricultural plants like hemp (Cannabis sativa L.). Hemp offers characteristics that are similar to wood properties. In line with this research, three-layered particleboards under utilization of hemp material were developed. The hemp was used in combination with industrial produced particles to find out which amount of wood can be substituted by hemp and further to investigate which decreased densities can be realized by the use of hemp. Hemp can be used for the production of lightweight particleboards due to its lower bulk density compared to wood. All developed hemp/wood based particleboards were produced under industrial parameters in laboratory and pilot scale using conventional urea formaldehyde-resin, hardeners, and hydrophobic substances. The mechanical technological properties of all produced innovative particleboards and reference particleboards were determined according to current DIN/EN standards. In detail density profile, bending strength, internal bond strength, surface strength, and thickness swelling were determined. Compared to the produced reference particleboards, consisting only of wood particles, the developed hemp/wood particleboards possessed better mechanical-technological properties. Furthermore it was realized to produce particleboards with densities of 550 kg/m³ by using hemp due to its low bulk density which fulfills the given DIN/EN requirements. As an overall result we found out that hemp is a real alternative to nowadays used wood for the production of particleboards in general and for the production of lightweight particleboards in particular.
