This paper proposes an indirect-mode forced convection solar dryer equipped with a PV/T air collector. The collector generates both heated and electrical energy, which are used to force in the dryer. Experiments were carried out on selected tomato slices for temperature humidity readings as well masses of dried samples instantaneously recorded two days. A thermal analysis was performed drying s...

Hebel brick is used in making the walls of house. One materials hebel bricks sand. The water content sand will affect quality bricks. less sand, better In order to get with a little content, it necessary do drying process. To overcome this problem, rotary dryer for using renewable energy, particular biomass energy sources was designed. It can be placed quarry near river or beach. designed have ...

In preparation for routine deployment in a network of greenhouse gas monitoring stations, we have designed and tested a simple method for drying ambient air to near or below 0.2 % (2000 ppm) mole fraction H2O using a Nafion dryer. The inlet system was designed for use with cavity ring-down spectrometer (CRDS) analyzers such as the Picarro model G2301 that measure H2O in addition to their princi...

who offered both ever-insightful comments and encouragement. My committee member Matthew Dryer, who spent much of his time reading and commenting on this project, in spite of his extremely busy schedule. My committee member Leonard Talmy, who gave me support and warm encouragement.

The disposal of Waste Activated Sludge is a major problem. The paper presents several disposal routes. The ultimate steps in these routes are indirect drying and subsequent incineration. Although the design of the indirect dryers is straightforward from a required heat input, operating temperature difference between sludge bed and heating medium and the heat transfer coefficient, this coefficie...

Chemical sanitizers are routinely used during commercial flume washing of fresh-cut leafy greens to minimize cross-contamination from the water. This study assessed the efficacy of five commercial sanitizer treatments against Escherichia coli O157:H7 on iceberg lettuce, in wash water, and on equipment during simulated commercial production in a pilot-scale processing line. Iceberg lettuce (5.4 ...
