The purpose of the paper is to present a concept of energy efficiency and financial evaluation of counterflow dryer. Energy efficiency and many other efficiency indexes of the dryer and all additional devices like heater, heat exchangers, tubing and fans are calculated. Expert system provides also the financial evaluation of the investment. Many investments could be considered. The system provi...

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...

In this study rhubarb stem slices were dried as single layers with thickness of 3 mm in the inlet air temperature range of 50-70  and air velocity of 1 ± 0.2 m/s in a laboratory scale cabinet dryer. The effect of drying air temperature on the drying characteristics was determined and the relationship between the drying parameters with temperature and moisture content was examined. Moisture tran...

Abstract Pumpkin, one of the most famous cultivars from Cucurbita moschata , is a rich source carotenoid. However, having high water content (above 80%) makes pumpkin extremely perishable, and difficult to be processed stored. Therefore, needs dehydration process in which could remove moisture product but still able uphold its natural color minimum nutrient losses. We have carried out comprehen...

Dried fruits contribute immensely to breakfast menus and snacks for most people. A wooden cabinet dryer was fabricated used dry mango, pineapple papaya assist processors micro-, small medium-scale enterprises (MSMEs) gain economic advantage of dried reduce the high postharvest losses fruits. The performance assessment a conducted determine its effect on weight (4.8–12.0 kg), yield (12.4–14.4%) ...

The therapeutic qualities of Alternanthera brasiliana and Cassia alata are due to the phytochemicals contained in these plants. This research was conducted study phytochemical analysis leaf extracts plants using methanol, hexane, chloroform solvents. leaves were collected, cleaned, dried for eight hours at 60°C a cabinet dryer. Using solvent extraction method, extract made. Qualitative quantita...
