the objective of this study was to investigate the drying kinetics of oyster mushroom, pleurotus ostreatus mushrooms were dried using a cabinet-type convective dryer. air temperatures of 50, 60 and 70 oc were used for the drying experiments. the experimental drying data were fitted to different theoretical models to predict the drying kinetics. nonlinear regression analysis was performed to rel...

This paper presents some results that were obtained in fault diagnosis for a wood-drying process. It is diffcult to detect and diagnose faults or failure in the drying process due to complex dynamic nonlinearity, coupling effects among key variables, and process disturbances caused by the variation of lumber sizes, species and environmental factors. In this paper, a real-time fault diagnosis al...

1. APPLICATION OF FULL FACTORIAL DESIGN IN THE MEASUREMENT OF DRYING RATES OF A ROTARY DRYER Drying is a physical separation process which enables to remove the liquid phase from a solid, semisolid or liquids by means of thermal energy. The aim of the experiment is to observe how various operational parameters affect the drying process in a rotary dryer. In drying process, heat is transferred b...

The aim is to investigate the eff ects of stepwise blanching and its combination with drying on rheological properties and change of color in pumpkins (Cucurbita moschata). 1 cm thick samples were immersed in water at 55 °C for diff erent times, followed by diff erent holding times prior to inactivation of the enzyme (97 °C/5minutes). Controled samples were obtained after blanching at 97 °C for...

Saffron is the most expensive spice and is significantly valuable in non-oil export. Drying process of saffron is considered as a critical control point with major effects on quality and safety parameters. A suitable drying method covering standards and market requirements while it is costlty benefitial and saves energy is desirable. Solar drying could be introduced as an appropriate procedure ...

Drying temperature and time effect on oil quality parameters of both seed and kernel from a sunflower hybrid of potential high oil content was evaluated. Drying tests were carried through two treatments of thin layer drying, consisting the first in getting the equilibrium moisture content and the second a safe storage moisture value, both in a range of temperatures from 25 °C to 90 °C. Prolonge...

Supercritical carbon dioxide has replaced many liquid organic solvents in industry due to its tunable solvent properties, environmental friendliness, and easily achievable critical parameters. The unique properties of supercritical fluids in general, such as gas-like diffusivity and zero surface tension, make them particularly applicable to the field of conservation. This presentation reports o...
