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...

Seasonal distributions of the western cherry fruit fly, Rhagoletis indifferens Curran (Diptera: Tephritidae), in sweet cherry (Prunus avium (L.) L.) (major host), black hawthorn (occasional developmental host) (Crataegus douglasii Lindley), and other trees were determined in a ponderosa pine ecosystem in Washington state, USA. The hypothesis that most fly dispersal from cherry trees occurs afte...

In this study, applications of ultrasound in food drying processes have been reviewed. High frequency ultrasonic treatment can be used in food drying processes as a pretreatment or for the improvement of the main process and the traditional driers. Ultrasonic waves at low frequency can also be used as a diagnostic method for measuring properties of the final dried products and controlling the d...

The effects of pretreatment solution (dipping in boiling water, salty boiling water, ethil oleat) were studied on drying kinetic of sour cherry. The thin-layer drying of sour cherries were carried out at three air temperatures of 50, 60 and 70°C and airflow velocity of 1 m/s. The experimental data were fitted to several thin-layer drying models such as Newton, Henderson and Pabis, Page, Logarit...

The aim of the work was to evaluate effect hot air and infrared drying on content total polyphenols anthocyanin dyes in selected types small fruits. In we used chokeberry (Aronia melanocarpa Michx.) variety Nero, elderberry (Sambucus nigra L.) Haschberg, sour cherry (Prunus cerasus Fanal, red currant (Ribes rubrum Lake, black nigrum Triton, elaeagnus (Elaeagnus multiflora Thunb), raspberry (Rub...

Kim, M.H., Kim, S.M., Kim, C.S., Park, S.J., Lee, C.H. and Rhee, J.Y. 2002. Quality of Korean ginseng dried by a prototype continuous flow dryer using far infrared radiation and hot air. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 44: 3.473.54. This study was performed to examine the effects of infrared (IR)/hot-air combination drying on some quality attributes of Korean ...

We studied the timing of reproductive maturity of cherry fruit fly, Rhagoletis cingulata (Loew), a key pest of sweet and tart cherries in the eastern United States. To determine when cherry fruit fly females become reproductively mature in managed and natural habitats, we deployed traps in sweet and tart cherry orchards and nearby stands of the ancestral host tree, black cherry. Flies were remo...

Abstract—High moisture content in fruits generates post-harvest problems such as mechanical, biochemical, microbial and physical losses. Dehydration, which is based on the reduction of water activity of the fruit, is a common option for overcoming such losses. However, regular hot air drying could affect negatively the quality properties of the fruit due to the long residence time at high tempe...
