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...

drying characteristics of green pea (pisum satium) with an initial moisture content of 76% (db) was studied in a fluidized bed dryer assisted by microwave heating. four drying air temperatures (30, 40, 50 and 60ºc) and five microwave powers (180, 360, 540, 720 and 900w) were adopted. several experiments were conducted to obtain data for sample moisture content versus drying time. the results sh...

Spray drying is a common unit operation across many industries due to the ability to control bulk powder properties and isolate dry product from a liquid feed in a single operation. For the pharmaceutical industry, spray drying offers the control of physical properties of crystalline or amorphous active pharmaceutical ingredients (APIs), as a neat or formulated drug product that can lead to imp...

This research presents an experimental analysis of a counter flow spray drying process using water and skim milk as feed. The study was performed by examining the droplet size distribution sprays temperature profiles in dryer. influence air inlet temperature, mass rate, feed on temperatures dryer evaluated. evaporation deposition zones were found to be highly dependent size. obtained results sh...

Drying via solar energy is an environmentally friendly and inexpensive process. For controlled bulk level drying, a greenhouse dryer the most suitable dryer. The efficiency of can be increased by using thermal storage. agricultural products dried in greenhouses are reported to higher quality than those sun because they shielded from dust, rain, insects, birds, animals. heat storage-based was fo...

In many industrial applications where compressed air is used it necessary to increase the quality of by decreasing its humidity. This done either a condensation or adsorption dryer in compressor circuit. this article, focus on an dryer. The briefly described together with function and selected range adsorbents suitable for drying. paper further deals development mathematical model humidity whic...
