Dates are considered high energy nutritional fruits as they packed with plenty of minerals, vitamins and sugars. Among various options available for processing value addition, dry dates one the best possible alternatives to convert doka/khalal stage fruit into a product. However, technology their production is limited few traditional date growing countries research in expanding areas. Thus, pro...

In the present study, the application of a BP neural network for prediction of the moisture content of barberry fruit (berberis vulgaris) during drying was investigated. The important parameters namely, pretreatment (heat shocking, olive oil + K2CO3 and NAT), air drying temperature (60, 70 and 80oC), air drying velocity (0.3, 0.5 and 1 m/s) and time (s) were considered as the input parameters a...

This work aimed to discuss effects of pulsed vacuum drying (PVD) at different temperatures (45°C, 50°C, 55°C and 60°C), durations (5 min, 10 min 15 min) multi-stage heating on kinetics, colour attributes, phenolic compounds antioxidant capacity chrysanthemum (Imperial chrysanthemum). Results indicated that successive temperature increase reduced the time enhanced rate moisture diffusivity. Lowe...

Leather manufacturing involves a crucial energy-intensive drying stage in the finishing process to remove its residual moisture. Determining drying characteristics of leather is vitally important so as to optimize the drying stage. This paper describes an analytical way for determination of the drying characteristics of leather. The model presented, is based on fundamental heat and mass tra...

Background: Drying is the one of the oldest methods for increasing the shelf life of food products. The objective of the present study was evaluation of effect of different drying temperatures on drying time and storage quality parameters of in-shell hazelnut. Methods: Hazelnuts were dried as a thin layer at three temperatures (40, 50, and 60 °C). The time required for drying and quality param...

Sun drying is a well-known food preservation technique that reduces the moisture contents of agricultural products. Shrinkage, rehydration ability and color of food materials during air drying adversely affect the quality of the dried products. Since all fresh tomatoes can not be consumed at the time of harvest, preservation provides a larger market, allowing consumers to buy the preserved toma...

Non-uniform stresses, strains and microcracking of the concretes with three coarse aggregate sizes (5–10 mm, 10–16 16–20 mm) dried under 40% relative humidity (RH) for 60 days were quantified using digital image correlation lattice fracture modelling. The influencing mechanism size on drying-induced concrete was clarified: (1) As decreases, propagation paths are increased, which increase number...

The aim of this study was to evaluate the sensitivity of Campomanesia adamantium seeds to desiccation by drying in activated silica gel (fast) and under laboratory conditions (slow). To assess the sensitivity of the seeds to desiccation, we used drying with silica gel and drying under laboratory conditions (25 °C), in order to obtain seeds with moisture content of 45, 35, 30, 25, 20, 15, 10 and...
