Conservation of agricultural crops and minimization of grain losses is challenging issue in the present scenario. Effective use of thermal energy for drying of paddy and other cereals for maintaining proper quality is the quality drying process. Natural convection grain dryer is quite suitable for under developed and developing countries like India where rural electrification and advanced dryin...

Abstract In many geotechnical applications, especially in the study of weather-induced landslides, a reliable soil hydraulic characterization unsaturated conditions is required. Currently, experimental techniques that neglect hysteresis represent greatest limitation to landslide forecasting. this paper, procedure obtain an on natural pyroclastic samples proposed and verified. The approach enabl...

The study was conducted to evaluate the effect of pre-treatments (0.1%KMS, 0.2%KMS, 0.3%KMS and blanching) and drying methods (mechanical drying and solar drying) on the dehydration and rehydration characteristics of carrot. The two drying methods yielded dehydrated products with different dehydration ratio, rehydration ratio, co-efficient of reconstitution and moisture content in both the dehy...

Abstract The paper applies the Structure from Motion photogrammetry technique to measure three-dimensional shrinkage deformations of a cylindrical specimen during drying. A clay–binder mixture was statically compacted, and its behaviour observed for four weeks with newly established photogrammetric system. complete surface information including XYZ coordinates RGB values then reconstructed form...

In this paper, a bespoke stress and temperature controlled direct shear apparatus to test soil-geosynthetics interfaces is introduced. By adopting the apparatus, series of ‘rapid loading’ tests creep were conducted on Clay – Geosynthetic Drainage layer (GDL) assess functionality apparatus. The experimental results indicate that, modified can allow deformation behaviour under environmental durin...

The Drying process is one of the most important factors which are effective on the milling quality of rice and its economic value. In order to investigate the effect of dryer parameters on milling quality of rice and their relationships, one of the usual rice varieties (Binam) of Gilan province with an average milling quality and the initial moisture content of 20.5% was selected. Drying proces...

The purpose of this study was to obtain the best anthocyanin pigment extract powder from 3 types of drying process, vacuum drying, spray drying, and  freeze-drying. The duration and temperature for each type of drying process are 15 h with temperature of 40 oC, 2 h with temperature of 120 oC (inlet) and 60 oC (outlet), 24 h with temperature of -50 o</su...
