in this paper the energy and exergy analyses in chamber drying process of thin layer drying of tomato in a forced solar drying was investigated. the experiments were carried out with two thicknesses of 5 and 7 and two airflows 0.5 m.s-1 and 1 m.s-1. during the experimental process, ambient temperature was between 22 and 36 , air relative humidity between was 14 and 50, and solar radiation range...

Water-based pressure sensitive adhesives are typically latex suspensions and are often coated onto silicone-coated paper prior to being contacted with the face stock. It is necessary to control drying conditions to achieve low residual moisture in the PSA without formation of defects, and mathematical models can be effective tools to determine appropriate drying conditions. We will present two ...

Purpose: This study evaluated the biological activity of five types mints (Peppermint, Spearmint, Chocomint, Applemint, Pineapplemint).Methods: Five were extracted with an ethanol solvent to compare total polyphenol and flavonoid content, scavenging activities DPPH ABTS radical, SOD-like activity, inhibitory effects elastase, tyrosinase, α-glucosidase.Results: All mint extracts confirmed be eff...

introduction: one of the most important aspects of food preservation is controlling the moisture of material such as fruits.dryingis considered as important method to controlbacteriasafely using reduction of moisture. the hot air drying method has been widely adopted in manufacturing of conventional dried food.nowadays, infrared radiation (ir) has significant advantages over conventional drying...

We investigated crack propagation in the drying process of a thin layer of calcium carbonate (CaCO3) paste experimentally. Cracks are induced by uniform desiccation from the top surface of a layer at the approximately same water content for various drying conditions. We found that the crack speed is a nonlinear increasing function of the drying rate at the cracking time although the tensile str...

date palm (phoenix dactylifera l.) with its delicious and nutritious bearing fruit (dates) is an important agricultural core in iran. to extend the shelf life of date palm fruit, some such methods of preservation as drying are suggested and drying influences physicochemical and quality characteristics of products, thus modeling of drying kinetics is one of the tools for process control. in this...

At equilibrium, colloidal particles in a subcritical liquid suspension are surrounded by a drying layer if the colloid has solvophobic interaction. Using Brownian dynamics computer simulations, we investigate the nonequilibrium response of this layer to a strong external driving force. We find that the driven colloidal particle dresses itself with more particles than in the equilibrium drying l...

In a randomized, double-blind controlled trial, 42 children with irritable bowel syndrome (IBS) were given pH-dependent, enteric-coated peppermint oil capsules or placebo. After 2 weeks, 75% of those receiving peppermint oil had reduced severity of pain associated with IBS. Peppermint oil may be used as a therapeutic agent during the symptomatic phase of IBS.
