Spray drying is presently one of the most interesting technologies in the pharmaceutical industry. The process shows a remarkable capability in manipulating powder/particle attributes such as size, morphology, density and level of residual solvents. This flexibility led to its application in a variety of powder formulations and advanced solid forms: from very fine powders for inhalation to larg...

Variation of colour and selected physical and mechanical properties related to artificial drying of sawn silver birch (Betula pendula Roth) timber from plantations. ...

the efficiency of oil extraction from oil seeds is affected by seed harvesting time, drying methods, seed storage conditions and finally the means of seed transportation to the factory. to determine the grain moisture content at harvest  and its effect on seed while on drying trails, (employing different canola dryers), a study was conducted in mazandaran province in 2009. a factorial complete ...

the objective of this study was to investigate dehydration kinetics of barberry (berberis vulgaris l.) at different drying temperatures (60 ºc, 70 ºc, 80 ºc), air velocities (0.3 m s-1, 0.5 m s-1, 1 m s-1) with two types of pretreatment. drying time and colour quality during dehydration were experimentally determined. barberries were dried from the initial moisture content of 73.44% (w.b.) to t...

A new advanced microwave drying technology has been developed using a continuous dryer combined with an air cooler. Principle of the new technology consist in using microwave absorption filters made from special porous ceramics which act as both absorbent and transparent material for microwaves. Ceramic slabs reduce intensity of microwave radiation to such a extent which prevents overheating or...

Background: Nowadays, colostrum has been known as a considerable and valuable by-product of large-scale dairy production in the world. The main objective of this study was to evaluate the effects of pasteurization, spray-drying and freeze-drying methods on bacterial loads and Immunoglobulin G (IgG) level of bovine colostrums. Methods: Colostrum samples were collected from the first milking pos...

Drying represents one of the oldest unit operations employed in industrial processes. Drying is viewed as a process of simultaneous heat and mass transfer. Porous Clay-like material undergoes stresses due to non-uniform distribution of temperature and moisture induced by heat and mass transfer respectively. The aim of this work is to simulate the stresses induced by heat and mass transfer durin...

Background: In the recent decade, artificial drying has been one of the most important needs of the pharmaceutical industries. In addition, different drying methods have different effects on the quantity and quality of the essential oils produced from medicinal plants. Objective: The main objective of this study was to evaluate the effects of different drying methods (shade and oven drying a...

An innovative and energy efficient sludge dewatering technology has been developed. The technology, impulse drying, involves briefly contacting the sludge under pressure with a heated surface. A unique feature of impulse drying is that the majority of moisture removal occurs as lipid water. A pilotand laboratory-scale demonstration was performed on low ash primary paper mill sludge. The pilot-s...

this study evaluated the use of the solar dryer at esfahan agricultural research center for drying prunes. a factorial experiment was carried using a randomized complete block design with four replications. the four methods used to accelerate prune drying were: control group (no treatment), mechanical perforation at one week of drying, blanching, submersion in australian cold dip method. the dr...
