Recently, consumers have become more concerned with foods contain natural ingredients in terms of health and economic. Hence, in this study, the effects of concentrate of smoked and sun dried raisin were investigated at 3 levels (1, 3 and 5%) as a natural humectant to improve the quality and shelf life of flat bread. Results showed that addition of smoked and sun dried raisin improved quality a...

Raisins have been widely consumed for many years all around the world, and different grape cultivars drying techniques are used in their production. Recently, mechanical systems to overcome any undesirable effects that arise from sun-drying with require fewer pesticides minimize risk of residues. Both seeded seedless were preferred past; however, increasingly purposes addition use as table grap...

Drying is a necessary step before sewage sludge energetic valorization. Paddle dryers allow working with such a complex material. However, little is known about sludge flow in this kind of processes. This study intends to set up an original methodology for sludge residence time distribution (RTD) measurement in a continuous paddle dryer, based on the detection of mineral tracers by X-ray fluore...

Solid biofuels, such as bark, forest residues, sawdust, and wood chips are important mill fuels in the forest industry. They are combusted in combined heat and power plants (CHP-plants) to generate heat and electricity for pulp and paper making processes. Biofuels usually have high moisture content. The high moisture content decreases the effective heating value of fuel and makes the operation ...

A new type of spray dryer was developed for drying milk and the like efficiently. To this end, freely rotatable propellers powered with air-flow were placed in chamber to increase thermal efficiency product yield newly dryer. Milk samples dried both system a standard compare efficiencies yields each. It observed that had caused change flow direction air, decreased temperature walls, increased d...

After natural fermentation and solar drying, sour cassava starch acquires expansion property. Traditionally, drying occurs without protection, consequently physical contamination can arise. Thus, the aim of this study was to produce using a low-cost dryer prevent contamination, whilst retaining The samples were characterized in relation chemical composition, microscopy contaminants, as well exp...

The processing of dried betel nut by the people West Kalimantan consists 2 stages, namely drying and stripping nut. process usually carried out farmers is directly in sun, smoking uses fire to heat. method areca nuts takes about 14-15 days. This study will examine problems faced nuts. Based on issue nuts, it necessary have an alternative that more efficient. Areca machine obtain relatively quic...

The present work presents a hybrid solar thermal drying of Tilapia fish to improve the product quality and satisfy importers. developed dryer utilized direct drying, air heater backup unit which sustains process during night, cloudy rainy weather conditions. Besides, new feature utilizes flue gas exhausted from enhance updraft in chamber by re-injection gases chimney. initial moisture content u...

Drying of green peas in a Fluidized Bed Dryer (FBD) with inert particle, heated by combined sources of hot air and InfraRed (IR) radiation, has been experimentally and theoretically studied. For this purpose, an experimental set up was constructed. This setup was composed of a cylindrical bed dryer containing some inert particles which are fluidized by hot air. Some infrared lamps were also pla...

This study was conducted with the development of instant fish soup mix and finding out the effect of fish powder on it. Ingredients of soup mix were cooked and dried up to desired moisture content. The drying or dehydration was done by using a mechanical dryer (Cabinet dryer) at constant air flow rate and constant temperature with varying thicknesses. After drying the dried products were ground...
