Cereals are generally harvested at 20-23% moisture content to avoid shattering losses therefore it is necessary dry the paddy lower contents (13-14% wb) for safe storage and further processing.A solar-powered airinflated grain dryer was designed, fabricated tested drying of paddy. Different combinations obtained from two different levels upper transparent polyethylene sheet thickness (200 micro...

A new semi-theoretical thin-layer model of the fluidized bed drying of Echium amoenum Fisch. & C.A. Mey. petals has been developed. Experiments were conducted under different conditions: temperatures of 40, 50 and 60 °C, and air velocities of 0.5, 0.75 and 1.0 m/s, until the moisture content decreased to 0.04.-0.06 kg of water per kg of dry matter. Drying processes in the fluidized bed were com...

J. Zych, J. Kolczyk, Ł. Jamrozowicz, AGH University of Science and Technology, Faculty of Foundry Engineering, Kraków, Poland Multi-layer ceramic moulds are built of slurry and a refractory material forming their matrices. From the moment when the European Union introduced regulations concerning the environment protection requiring substitution of alcoholic binders by aqueous binders, several d...

Ł. Jamrozowicz, J. Zych, J. Kolczyk, AGH University of Science and Technology, Faculty of Foundry Engineering, Kraków, Poland Investigation results of the drying rate of the selected protective coatings (water and alcohol) are presented in the article. Coating drying rate was determined for the first and second layers. The coating was applied to moulding sand cores. The rate of drying coatings ...

The effect of different concentrations of sugar solution (hypertonic) (30%, 45% and 60% w/v) and carboxyl methyl cellulose (CMC) (0%, 1% and 2% w/v) coating on freeze drying of apple slices was studied. In total, nine treatments with respect to concentrations of hypertonic solution and coating layer were prepared to analyze their influence on the physical and chemical properties of freeze dried...

Damask rose (scientific name: Rosa Damascene) belongs to Rosaceae families and is valuable in medicine. In this study, the influence of air temperature and velocity are investigated on hot air dryer of the rose petals. Artificial drying of the agricultural products is one of the most common maintenance procedures. Suitable drying methods reduce the waste and damage during the storage and save t...

utilization authorities in sewage companies considered to sludge dewatering methods due to problems and challenges in this field. dewatering by sludge drying beds is considered in present study. this method is preferred to mechanical methods due to the need for very simple technology. due to restriction of natural dewatering, we tried to eliminate some of these limitations by the tests and stud...

The mechanism responsible for unusual mechanical properties of tension wood gelatinous fiber (Gfiber) was investigated. We discussed origins of high tensile growth stress, high drying shrinkage, and rapid increase of Young’s modulus due to drying, in association with microscopic structure of gelatinous layer (G-layer). Anatomical, crystallographic, and micromechanical approaches were employed. ...
