a thin layer solar drying method was compared with a traditional method (sun drying) of paddy drying, with their effects on quality characteristics of two varieties of iranian rice (kamphiroozi and sazandegi) studied. solar drying process was conducted in a passive, mixed mode type solar dryer at about 50ºc for 90 minutes. in sun drying method this process took 8-10 hours at a mean temperature ...

Dill (Anethum graveolens L.) and parsley (Petroselinum crispum Mill.) were dried by using sun and oven (50oC) drying methods. Oven drying decreased the drying time approximately 50% when compared to the sun drying method for both herbs. K, Ca, P, Mg and Na were the most abundant elements in dill and parsley samples. Oven-dried samples had higher mineral values than that of the su...

the objective of this study was to examine the effects of the fluidized-bed drying me-thod on the final quality of two varieties of iranian rice, medium- and long grain. the re-sults were compared to that of paddy drying using a traditional method. rough rice was treated in the fluidized bed drier at 140ºc for 2 minutes. similar samples were dried for 8-10 hrs by the traditional method. dried s...

To establish the most convenient and effective method to dry tangerine peels, different methods (sun drying, hot-air drying, freeze drying, vacuum drying, and medium- and short-wave infrared drying) were exploited. Our results indicated that medium- and short-wave infrared drying was the best method to preserve nutraceutical components; for example, vitamin C was raised to 6.77 mg/g (D.W.) from...

Different drying methods viz., Sun drying, shade drying and tray drying (temperature 45, 55 and 65 0C) were used for dehydration of curry (Murraya koenigii) leaves for optimal retention of color and its constituents. It was observed that the time required for tray drying was less (27%), when compared to sun and shade drying. Tray dried (550C) curry leaves had maintained nutritional constituents...

In this study, the effects of the storage duration of coffee cherries after harvest before putting out for sun drying on the kinetics of drying, fungi development and the variation of physicochemical content were evaluated. The results showed that the longer coffee cherries were stored after harvest before putting out for sun drying, the quicker they dried. Indeed, the drying durations were 19,...

Drying of wild pomegranate seeds was carried out by using various drying methods to evaluate the best and feasible method of drying and to produce a value added product “anardana”. The various drying methods used were vacuum drying, oven drying, sun drying, poly-tent house drying and room drying. The experimental results showed that out of all the drying methods, sun drying method for anardana ...

BACKGROUND The current typical drying methods for red ginseng are sun drying and hot-air drying. The purpose of this study was to investigate drying characteristics of red ginseng by using far-infrared drying. METHODS The far-infrared drying tests on red ginseng were conducted at two drying stages: (1) high temperature for 24 h drying and (2) low temperature drying until the final moisture co...
