In this research a fuzzy model is developed for a rotary dryer. It is applied to the pilot plant rotary dryer located in the Control Engineering Laboratory at Oulu University. Firstly, a literature review looking at the current situation of fuzzy modelling and comparison of different methods is done. One modelling method is then applied to the building of the model from data. The rule parameter...

Among available technologies, disk and paddle dryers are often encountered in France to process municipal sewage sludge but their thermal design is still a question of know how rather than scientific knowledge. From experiments performed on an industrial Naratherm paddle dryer and the literature, a simple model has been developed. The dryer is divided into two parts depending on the sludge cons...

a mixed solar dryer with a specific mechanism to vary the tilted angle of collector, is utilized to fulfill all tests. the efficiency of the dryers is low because of various reasons such as heat loss of air in an open flow circuit. getting air back toward the air inlet of dryer can increase the efficiency of dryer and decrease drying process period. a new mechanism considered for dryer which co...

In this paper, water content from celery, corn, and sour cherry were removed through tunnel, fluidized bed, and fluidized bed with microwave dryers. One day before performing the experiments, the fruits were put into a refrigerator and were ground into slices with average dimensions of 5×8×8 mm. For each experiment, 40 g of the samples were inserted in dryers. Moisture content in the samples wa...

Application of microwave for drying of ashwagandha roots was investigated. A laboratory convective microwave dryer was already developed which had the provision of regulating of air temperature, air velocity and microwave power. Ashwagandha roots of uniform size were used in the drying experiment which were carried out at air temperatures of 40, 50 and 60°C, air velocities of 1.0 and 1.5 m/s an...

Maize is an important staple in Africa, which necessitates immediate drying to preserve the postharvest quality. The traditional of maize open sun prone adverse weather and extraneous contamination. In this study, performance inflatable solar dryer (ISD) was compared direct (DSD) Gombe Town, Wakiso District (Uganda) by analysing moisture content, yeasts, moulds, aflatoxin, colour. maximum tempe...

It is the oldest and most common traditional food preservation method known to dry by laying products under sun. However, if product in direct contact with sun light, there a decrease color nutrient values of product. To solve these problems, solar dryers have been developed which can be utilized due indirectly effect In this study, kiwi rings were dried using osmosolar dehydration as combinati...
