The paper describes the detailed techno-commercial analysis done on a 46 m2 solar air heating system developed in a food processing industry. The solar air heating system was connected to an indoor drier through a duct. A detailed performance analysis was undertaken on the system by loading with 75 kg of ripe mango flake. The product loaded was uniform in size having a thickness of 4mm. On a cl...

Postharvest losses (PHL) are incurred in the tomato value chain in Ghana and solar drying of tomato is a promising technology for reducing the loss. However, there are concerns on the usage, functionality and sensory appeal of the dried products to consumers, compounded with the lack of information and research on dried tomato processing in Ghana. A survey was carried out by administering semis...

this study evaluated the use of the solar dryer at esfahan agricultural research center for drying prunes. a factorial experiment was carried using a randomized complete block design with four replications. the four methods used to accelerate prune drying were: control group (no treatment), mechanical perforation at one week of drying, blanching, submersion in australian cold dip method. the dr...

Fruit leathers are dehydrated fruit products which are eaten as snacks or desserts. They are flexible sheets that have a concentrated fruit flavor and nutritional aspects. Most fruit leathers are prepared by mixing fruit puree and other additives like sugar, pectin, acid, glucose syrup, color, and potassium metabisulphite and then dehydrating them under specific conditions. Various drying syste...

Nigeria, as one of the countries in African continent has its challenges regarding to agricultural crops cultivation and preservation methods. Traditional methods preserving are commonly adopted by local populace over solar dryer appliances. The reason for these includes being cheaper method, does not require much technical know-how, is easily learnable, area drying crop produce unlimited etc w...

Drying is one of the oldest and most important preservation method for food in which by reducing water activity shelf life can be increased. In present investigation, fresh ginger was pretreated calcium oxide solution at different concentrations. Solar drying three temperature levels viz., 55, 65 75o C loading densities 0.147 g/cm2, 0.176 0.206 g/cm2 respectively were used investigation. Result...
