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...

Low-cost drying technologies suitable for rural farming areas are presented. Some of the important considerations with regard to their suitability include: 1. Low initial capital; 2. easy-to-operate with no complicated electronic/ mechanical protocol, and 3. effective in promoting better drying kinetics. The drying technologies that were selected include fluidized bed, spouted bed, infrared, so...

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 transfe...

The effect of air temperature, air velocity, and sample shapes (circle and square with the same cross-sectional area) on kinetic drying of potato slices in a tunnel dryer was investigated experimentally and a suitable drying model was developed. The experiments of drying of potato slices were conducted at an air temperature of 45-70°C with an air velocity 1.60 and 1.81 m sec(-1). Results showed...

The thin layer drying of pine forest residues consisting of bark, needles, leaves, and chips was experimentally conducted at air temperatures of 40, 50, 60, 70, and 80C. Physical and chemical properties of fractionated forest residues were determined to evaluate its fuel properties. The experimental data obtained from thin layer drying study were fitted with Lewis, Page, and Henderson and Pabis...

Citation: Haggag YA and Faheem AM (2015) Evaluation of nano spray drying as a method for drying and formulation of therapeutic peptides and proteins. The high sensitivity of peptides and proteins to physicochemical stresses during processing and storage is the major hurdle against its pharmaceutical applications. Peptide-based drug formulations are commonly prepared as solid dosage forms becaus...

The present study evaluates the effect of drying treatments such as convective air drying and freeze-drying on the colour, texture, chemical properties (ash, sugars, fibre and vitamin C), phenolic compounds and antioxidant activity of cucumber. The trials in the convective chamber were done at 40 oC and 60 oC, in the drying tunnel were done at 60oC and in the freeze dryer were done at -50oC. It...

football participation requires considerable utilization of both aerobic and anaerobic energy systems to match the high energetic demands of the sport. the consequent stresses imposed on the physiological and metabolic systems carries players to the threshold of exhaustion during match-play, from which they are required to recover in preparation for the subsequent game. a high number of players...

labor pain is one of the most tiresome types of pain. so human has been seeking to allay this pain until now. administration of a suitable agent such as entonox during labor is very beneficial for childbirth outcomes. entonox can be administered in two ways: intermittently and continuously. the aim of this study is to demonstrate whether continuous method is as safe as intermittent method? this...
