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 research, papaya slices with dimensions of 0.5×2×5 cm3 were dried at 45 °c using a cabinet dryer in which drying air velocity and relative humidity were 0.9 m/s and 30%, respectively. the moisture diffusion coefficient of papaya was determined in this drying condition. mass transfer equation with its boundary conditions was solved based on finite difference method. finally, coefficient ...

The current study focuses on the life cycle assessment and an economic valuation of a natural convection solar greenhouse dryer in Western Maharashtra, India. Solar Greenhouse Dryer is active device that gains radiation incident to surface along with wind energy, it removes moisture from agricultural yield. combination energy primarily used rural settings; hence, very important analyse environm...

An experimental investigation was conducted to study the performance of a novel indirect type free convection solar dryer. The and conventional passive dryer were built. Solar irradiation temperature different locations recorded. air at drying chamber entrance, lower space, upper space temperatures besides thermal efficiency 68, 39, 49 85%, respectively, higher than one.

drying of agricultural products is a sophisticated process with high energy consumption. energy needed for sustainable development, is one of the biggest challenges facing humanity. the performance of a heat recovery assisted solar dryer was evaluated in this study. drying time, collector efficiency, energy consumption, solar fraction and energy recovery fraction were investigated at different ...

Animal and poultry manures have been recognized for centuries as organic fertilizers providing essential nutrients to crops and improving soil structure due to their large input of organic matter. Increasing demand for poultry and egg products has led to intensification of the poultry rearing process, resulting in large amounts of poultry manure. Drying can be used to reduce the environmental i...

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...

The ripe fig (Ficus carica L) fruits of cultivar cv., 'Deanna' were steam treated at 90°C and 10 psi for 5 min in autoclave. Steamed fruits were dipped in sucrose, glucose, fructose and invert sugar syrups at 50°Brix for 24 h for getting desired total soluble solids content. The treated fruits were further dried to 20% moisture in a cabinet dryer at 50-55°C. Good quality and acceptable dried fi...

Background: An outbreak of Stenotrophomonas maltophilia was observed in the cultures of bronchial aspirations. After systematic culturing of the scopes and reprocessing the equipment, it turned out to be a pseudo-outbreak caused by a failure of the disinfector to sterilize ultrasound scopes, subsequently resulting in cross infection of the bronchoscopes via the connecting tubes in the dryer. Ob...
