Use of ultrasonication, thermogravimetric analysis and newly developed hot-air drying platform for evaluation and optimization of drying processes of agricultural materials
Drying is one of the oldest and most complex unit operations in the food industry. Four billion tons per year of food are produced for human consumption worldwide, and about 20% of the products are dehydrated. Hot-air drying is the most widely used drying method for preserving fruits and …

Evaluation of Methods to Control Mold on Hardwood Pallets
… project were:<br />1.����To compare the drying cost and drying time for oak and poplar pallets for the following mold mitigation strategies for hardwood pallets: air drying, forced air drying (fan shed), kiln drying to 25% moisture content and chemical treatment, and<br …

The Impact of Vacuum-Drying on Efficiency of Hardwood Products Manufacturing
… like lean manufacturing. However, the lumber drying process where lumber is kiln-dried in large batches, can significantly increase manufacturing and inventory lead-time; and is a process that tends to limit how lean the remaining process can become. Vacuum drying has the potential to reduce …

Quality analysis of ultrasonically dried strawberry and comparison to conventional drying methods
Conventional, hot air drying is one of the most commonly used drying methods in the food industry for its simplicity, high productivity, and low capital cost. However, hot air drying has many limitations surrounding energy requirements, processing efficiency, and costs coupled with significant food …

Interactions of Flavor Compounds With Food Solids and Their Application to Volatile Retention During Drying
… with food solids were studied by measuring air-liquid partition coefficients of volatiles, sorption capacities of solids in aqueous solutions and in dry forms, and changes in thermodynamic parameters upon adsorption. The information gathered from studies on the interactions was related to …

Solar drying of green oak (Quercus spp.) lumber
… was made of the rates and quality of solar and air drying from the green condition of a mixture of red and white oak 5/4 inch lumber during winter conditions in Blacksburg, Virginia. The solar kiln was of a semi-greenhouse type, having a capacity of 150 board feet and provided with an air …

The use of bakery wastes as a nutritional source for fish
… of a production pellet were investigated. Air drying of bread at room temperature was found to be an effective method of reducing excess moisture with a reduction of 40% by simple air drying, and 60% by blowing the sir with a fan. Preservation of bakery waste pellets was found to be …

Energy efficiency of non-face brick production with particular reference to the drying process
… this study was to provide an efficient method of drying bricks, particularly for factories which were drying in the open air. The hollow ware possibility widened the scope of the study, and a dryer was designed to dry both hollow ware and solid bricks. A constraint on the dryer design was the …

Environmental-Stress Tolerant Formulations of Metarhizium anisopliae var. acridum for Control of African Desert Locust (Schistocerca gregaria)
… radiation and enhance spore survival during drying. Development of this formulation involved the following: 1) production of an infective spore-type in liquid culture that could survive drying; 2) coating spores during an air-drying process; 3) reducing formulation particle size for oil …

Separation of solvents from selected biopolymeric matrixes and aqueous mixtures by ultrasound
… of a commercial distillation column is fairly low, with a typical thermodynamic efficiency of less than 10% (Rush, 1980). There are two main reasons for its low efficiency. First, there are large irreversible heat-transfer losses in the phase-change processes of boiling a liquid and then …

Survival and chemical control of Cylindrocladium spp. inciting root rot of black walnut seedlings
Air drying of naturally infested soils (0.12 to 0.38% water or about -2,000 bars) resulted in no recovery of Cylindrocladium crotalariae microsclerotia, but rewetting soils to near field capacity for 1 to 4 wk before assay resulted in partial recovery from the air drying-induced decreased …

The drying of foods using supercritical carbon dioxide
Food drying techniques such as air and freeze drying are not ideal: high temperatures used during air drying result in degradation of nutrients and sensorial properties, while freeze drying is expensive and therefore only applicable to high value foods. As an alternative to such drying techniques, …

An investigation of selected effects of environment on the dry rot fungus <i>Serpula Lacrimans </i>
… the effects of lowered humidity and moving air flow on the activity of <i>S. lacrymans</i>. In the smallest and simplest of these, its growth and timberdecaying activities could be stopped by incubation at 86% relative humidity or by the application of a pumped air flow rate of 2.5 litres …

Removal of calcium sulfate deposits from waste acid treatment facilities
… revealed that, following the immersion period, “air drying" the material had an effect upon the behavior of the sample during the second immersion period. It was seen that the disintegration of more resistant materials could be facilitated by employing such a period for drying the material before …

Practical drying techniques for yellow-poplar S-D-R flitches
… the stress relaxation caused by high-temperature drying. Implementation of this S-D-R process in the Appalachian region has been limited as few mills in this area have this drying capability. The purpose of this study was to investigate the effectiveness of high-temperature and steaming treatments …
