in the present study, saffron was dried using a heat pump-assisted hybrid photovoltaic-thermal solar dryer. the effect of different drying air temperatures at three levels (40, 50, and 60oc) and two different modes of the dryer (with and without heat pump system) were investigated on drying behaviour of saffron. after collecting the pertinent data, eleven drying models were used to describe dry...

The behavior of rotating and non-rotating aggregated convection is examined at various horizontal resolutions using the hypohydrostatic, or Reduced Acceleration in the VErtical (RAVE), rescaling. This modification of the equations of motion reduces the scale separation between convective and larger-scale motions, enabling the simultaneous and explicit representation of both types of flow in a s...

Several studies have pointed out the dependence of low-cloud feedbacks on the strength of the lower-tropospheric convective mixing. By analyzing a series of single-column model experiments run by a climate model using two different convective parametrizations, this study elucidates the physical mechanisms through which marine boundary-layer clouds depend on this mixing in the present-day climat...

Leather manufacturing involves a crucial energy-intensive drying stage in the finishing process to remove its residual moisture. Determining drying characteristics of leather is vitally important so as to optimize the drying stage. This paper describes an analytical way for determination of the drying characteristics of leather. The model presented, is based on fundamental heat and mass tra...

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...

Spent grains from microbreweries are mostly formed by malting barley (or malt) and suitable for a further valorization process. Transforming spent waste to raw materials, instance, in the production of nontraditional flour, requires previous drying A natural convection solar dryer (NCSD) was evaluated as an alternative conventional electric convective (CECD) dehydration process local microbrewe...

Olive Mill Wastewater (OMWW) treatment is considered to be one of the main challenges that Mediterranean countries face. Although several procedures and technologies are mentioned in the literature, these techniques have several disadvantages or have been limited to laboratory pilot validation without posterior industrial projection. Recently, an advanced environmental friendly strategy for the...
