The moisture content obtained after dough sticks attaining the safe moisture content in open sun drying, tray drying, only microwave drying, sun cum microwave drying and convective cum microwave drying was found to be 8.42, 5.53, 6.23, 5.43 and 4.6% (db). The time required to achieve the above levels of moisture content were 14, 12 h, 24 min, (2.5h+17 min), 20+17 min for pearl millet sticks in respective dryers. The rate of drying was highest in only microwave drying but gives less quality product, followed by convective cum microwave drying, sun cum microwave drying, tray drying and open sun

Solar drying and convective oven drying of cherry tomatoes (Solanum lycopersicum) were compared. The changes in the chemical parameters of tomatoes and principal drying parameters were recorded during the drying process. Drying curves were fitted to several mathematical models, and the effects of air temperature during drying were evaluated by multiple regression analyses, comparing to previously reported models. Models for drying conditions indicated a final water content of 30% (semidry products) and 15% (dry products) was achieved, comparing sun-drying and convective oven drying at three di

Parabolic solar dryer developed by Nigerian Stored Products Research Institute was used to dry bell pepper. The drying rate, color changes and drying kinetics using some empirical modelling equations were determined. Open sun drying method was used as a control. Drying rate (2.11 kg/day) of the parabolic solar dryer was significantly higher than that of the sun drying (1.92 kg/day). Bell peppers dried under parabolic dryer retained their color better than those peppers under sun drying. Page model is the most suitable model to describe the drying kinetics of the bell pepper under solar drying.

Open sun drying is one of the oldest techniques employed for processing agricultural products. The local practice of drying the seaweed is by spreading it over a plastic sheet on the ground and exposing it to the sun. Unfortunately, such traditional practice of drying seaweed has led to increased risk of contamination of seaweed by dust and sand particles and other impurities, as well as seaweed often suffer from lower quality. This research was conducted to examine the effect of application of table type sun drying on quality of dried seaweed, through indicators of water content, level of imp

Traditionally, the processing of Gelidium seaweed into Gelidium jelly was very complicated, and involved repeated washing with water and sun drying for seven rounds. The seaweed, which is originally reddish-purple in color, turns yellow in color after the repeated washing and sun drying cycles. However, the sun drying process can only be used on sunny days. Therefore, this study evaluated an alternative method, halogen lamp drying, and compared the qualities of the product, Gelidium jelly, made using the halogen lamp drying and traditional sun drying methods.

Conventional open sun drying and shade drying were tested for different pretreatment curing of black pepper. The quality improvement and reduction in drying duration were exhibited for the sun-dried samples.

<em>The solar dryer has been specially developed and evaluated for its performance for drying of tomato slices. The loading capacity of the dryer was about 10 kg slices per batch. The drying characteristics of the dryer were studied and compared with respect to open sun drying method. The maximum temperature developed in the drying chamber of dryer was observed to be 52.63°C. Drying time for drying tomato slices from initial moisture content of 94% (wb) to final moisture content of 8.97% (wb) was recorded to be 12.5 h in said solar dryer whereas, 15 h was observed in the open sun drying.

Traditional methods of processing and drying sandfish [Holothuria ((Metriatyla)) scabra] result in poor quality and low value products in the market. The drying process generally involves smoking and sun drying which can leave scorch marks and smoke residue, and result in inadequate drying especially during poor weather. A combination of hot air drying and solar drying (Treatment I) was compared to the traditional process of smoke drying followed by sun drying (Treatment II) to determine the effect on product quality and price. Results showed that significant shrinkage occurred regardless of t

Drying involves removing moisture from food. Therefore, to preserve the phenolic and bioactive compounds such as curcumin, dimethoxy curcumin and bisdemethoxi curcumin, etc., an efficient drying method is considered necessary. The primary drying methods are sun drying, hot air oven drying and fluidized bed drying. Traditional drying methods result in the loss of volatile oil (up to 25%) by evaporation and destruction of some light-sensitive oil constituents. Three methods of drying Turmeric with pretreatments boiled/unboiled and whole/sliced (2.5 cm long) were compared on physical and quality

Abstract Red chili flakes simplicia should have a color and an aroma resembling those of fresh red chilies. Long-term drying of red chilies at high temperatures and high humidity can produce undesirable color changes such as dried simplicia chilies and blackish brown chili flakes. This can be overcome by using artificial dryers or sun-drying combined with the provision of strong wind gusts to reduce temperature and humidity, avoiding substances that cause changes in color and aroma. The purpose of this study was to determine the quality characteristics of red chili flakes obtained from sun-dry

Kencur (Kaempferia galanga L.) is an important ingredient in culinary and traditional medicine but has a limited shelf life due to its high moisture content. To overcome this, kencur can be processed into flour through drying. This study aims to analyze the effect of drying temperature on the drying time of kencur using three methods: sun drying, oven drying, and hybrid rack dryer, and to compare their efficiency based on drying duration, energy consumption, and drying capacity. The results show that the oven drying method requires the shortest drying time of 10 hours at 58°C with the highest

The leaf exudates collected from epidermal layer contain anthraquinone glycosides (aloins) mainly barbaloin (aloin A) and isobarbaloin (aloin B). Aloin A is used as a raw material for the production of diacylrhein, a potent drug prescribed for rheumatoid arthritis. Conventional drying of leaf exudates in open sun causes changes in physicochemical properties and altered aloin A and B composition.

The present research was undertaken to investigate the effect of various blanching and drying treatments on the vitamin C, �-carotene, iron, protein content and drying time of fluted pumpkin (Telfairia occidentalis Hook) leaves. The leaves were subjected to sun or oven drying alone or after blanching in boiling water, dilute citric acid (0.3%) or dilute potassium meta-bisulphite (0.5%). In the absence of blanching pre-treatment, oven drying resulted in shorter drying time for the leaves and a higher vitamin C content of the dried product than sun drying and there was no significant difference
