Gasification has become an attractive technology that is capable of producing a rich syngas from a range of biomasses and other fuels. This syngas can then be further processed into liquid fuels through Fischer-Tropsch processes to provide an alternative to current fossil fuels or to provide local markets with a competitive fuel. The purpose of this study was to construct a four-inch bench scal...

As a country that has many islands, our also lot of sea qhich means it produces fish, but fish quickly rot if left alone without preservation process. One the process.One processes can be by drying in sun, erratic weather make difficult for fishermen process, therefore system is made detect rain and disturbances such as cats using PIR sensor with an automatic control when rains or distrubnaces....

in this study, a laboratory scale continuous plug flow fluidized bed dryer was designed and constructed. a backward-curved centrifugal fan with a 4 kw electromotor was selected based on the maximum pressure drop in the minimum fluidization state and the ability to produce the velocity required for fluidization of the most granular agricultural materials. the fluidization chamber was a rectangul...

The study investigated the functional properties of HQYF (high-quality yam flour) from tubers of four dioscorea species. The tubers were processed into HQYF using two pretreatments (potassium metabisulphite: 0.28%, 15 min; blanching: 70°C, 15 min) and drying methods (cabinet: 60°C, 48 h; sun drying: 3 days). Significant differences (P < 0.05) were observed in pasting characteristics of flours a...

Cocoa (Theobroma cacao) contributes significantly to Ghana’s GDP and has made Ghana a recognized leader in the cocoa industry. However, there are myriad problems associated with bean quality. One such stems from farmers paying less attention required postharvest activities (fermentation drying) which quality losses. This study investigated effect of duration traditional heap fermentation period...

In the present study, a fruit dryer system that is controlled based on fuzzy logic is presented. A laboratory scale cabinet was developed which includes four sensors in different lengths for monitoring the cabin temperature and humidity. Fuzzy base controller is a new monitoring technique in food industrial machines that utilize sensors captured values as its input parameters to make a suitable...

Currently, the physicochemical quality of dried chillies is becoming a characteristic consumer choice. A study was conducted to investigate properties drying by vacuum tray dryer (VTD) when compared with sun (SD) and freeze-drying (FD). The highest capsaicin content lowest moisture achieved VTD technique. However, total phenolic antioxidant activity are in FD followed VTD. Furthermore, physioch...
