in recent years immense interest has been focused on the use of solar dryers especially when taking into consideration economical and ecological aspects and increasing in fuel costs. the aim of this study was to compare the qualitative factors of raisins made by five different drying methods. at the first step, pretreatments were applied to grapes (var. sultanas) and then the grapes were dried ...

Abstract In the production of fermented cabbage, cell juice cabbage is released, which highly saturated in biologically active compounds, but considered as a by-product. The aim this study was to evaluate quality parameters dehydrated using maltodextrin coating agent at various concentrations. experiment, used — spray dried on horizontal spray-dryer and maltodextrin, different concentrations (0...

This study examined the applicability of pomegranate peel extracts (PPE) and microencapsulated (MPE) in yogurts made with cow’s milk soy drink mixtures. For preparing PPE, powders were extracted by 50% ethanol an ultrasonic water bath. PPE was encapsulated using a spray dryer. Phytochemical composition antioxidant activity MPE determined 0.5% 1% used yogurt production. Physicochemical, rheologi...

The objective of this work was to determine the effects of blanching and two drying methods, open-sun drying and natural convection solar drying, on the quality characteristics of red pepper. A 2 × 3 factorial design with experimental factors as 2 drying methods (open-sun drying and use of solar dryer) and 3 levels of pepper blanching (unblanched, blanched in plain water, and blanched in 2% NaC...

A clothes dryer, however, might be fitted with a sensor-based feedback system that lets the machine measure the moisture content of the fabrics or the exhaust air, and turn itself off when the load is dry. Operating performance is enhanced and energy use is lowered as a result. The redesigned dryer might even be cheaper to buy, depending mainly on the cost of the components that comprise the el...

The drying or dehydration is the controlled heating of food products to evaporate quantified amount of moisture that is originally present in it. Drying of food products is essential to enhance the shelf life of the product without quality losses over an extended period of time. It is an energy intensive process. The fluidized bed dryer with heat pump is one of the efficient method to reduce th...
