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 ...

Dehydration of Mazafati Rutab is a method to prevent its spoilage. Dehydration is necessary for Mazafati Rutab because it contains too much moisture. If the moisture content of Mazafati Rutab is decreased properly, it need not be stored under refrigeration. The present study was carried out in an attempt to decrease the moisture content in order to increase the shelf life of Mazafati dates. Sam...

PURPOSE For many years research has been conducted on the development of resorbable, polymer, haemostatic materials designed to provide first aid and preliminary protection of injuries. The biological properties in vitro of a dressing in powder form called Hemoguard are expected to provide the ability to instantaneously stem bleeding with safe conditions of use. The aim of the study was to eval...

This work explores the use of both spray drying and d-glucosamine HCl (GLU) as a hydrophilic carrier to improve the dissolution rate of piroxicam (PXM) whilst investigating the electrostatic charges associated with the spray drying process. Spray dried PXM:GLU solid dispersions were prepared and characterised (XRPD, DSC, SEM). Dissolution and triboelectric charging were also conducted. The resu...

Mathematical models of drying are used for the purpose of understanding the drying process in order to determine important parameters for design and operation of the dryer. The jackfruit is a fruit with high consumption in the Northeast and perishability. It is necessary to apply techniques to improve their conservation for longer in order to diffuse it by regions with low consumption. This stu...

Magnetic resonance imaging (MRI) and other techniques are being used to investigate moisture transport in textiles. MRI revealed that moisture distribution in carpet is significantly influenced by the details of the vacuum extraction procedure used to remove excess water. Industrially relevant through-flow drying of carpet has been simulated on a laboratory-scale dryer as well as inside an MRI ...

Magnetic resonance imaging has been used to visualize moisture distribution in cut-pile nylon carpet following the dyeing and finishing process and before it enters the dryer. At moisture levels typical of those following hydro-extraction (i.e., ~70%), water is concentrated within the carpet yarns of the backing. From optical micrographs, it can be seen that this is the same region as the small...

The substances responsible for saffron’s characteristic quality are crocins, picrocrocin, and safranal. The drying process is critical to the saffron quality as measured by levels of secondary metabolites, crocin (color and anti-tumor properties), picrocrocin (taste), and safranal (aroma). Four different dehydration methods were evaluated: Iranian traditional method (room temperature); dehy...

The cause of initial burst release of hydrophilic macromolecular drugs from biodegradable polymeric microspheres was identified. Poly(D,L-lactic-co-glycolic acid) microspheres encapsulating fluorescein isothiocyanate (FITC)-labled dextran was prepared by a double emulsion solvent evaporation method. The extent of initial burst release was examined by varying the formulation process conditions s...

In this study, monolayer drying of kiwi slices was simulated by a laboratory-scale hot-air dryer. The drying process was carried out at three different temperatures of 50, 60, and 70°C. After the end of drying process, initially, the experimental drying data were fitted to the 11 well-known drying models. The results indicated that Two-term model gave better performance compared with other mode...
