Titanium and its alloys are wildly used in industries. Shrouded plasma spray can be considered as a useful technology to produce low oxide containing titanium coatings. In this paper, the effect of shroud spraying on chemical composition thickness coatings were investigated. plasma-sprayed deposited onto mild steel substrates. Air also for comparison under same parameters. Those then studied te...

BACKGROUND Bacterial contamination on touch surfaces results in increased risk of infection. In the last few decades, work has been done on the antimicrobial properties of copper and its alloys against a range of micro-organisms threatening public health in food processing, healthcare and air conditioning applications; however, an optimum copper method of surface deposition and mass structure h...

BACKGROUND Spray-drying techniques are commonly utilized in the pharmaceutical, dairy, and animal feed industries for processing liquids into powders but have not been applied to human blood products. Spray-dried protein products are known to maintain stability during storage at room temperature. STUDY DESIGN AND METHODS Plasma units collected at the donor facility were shipped overnight at r...

The aim of the present work was to study the effect of various process parameters on an aqueous-based film coating process of tablets performed in a side-vented perforated pan-coating apparatus. Results of preliminary trials indicate that spray rate, inlet air temperature, percentage solid content, atomizing air pressure and speed of rotation affected characteristics of coating. A 3 full factor...

Spray drying is a common drying technique in food industries to convert liquid to powder form. A good understanding on the dynamic behavior of the process is important to ensure proper control. The aim of this study is to develop empirical models for spray drying of whole milk powder and orange juice powder. A preliminary study on the effect of several inputs such as inlet air temperature, feed...

Two trials were conducted to determine the effects of irradiation of spray-dried blood meal and animal plasma on nursery pig growth performance. In Exp. 1, irradiation of spray-dried blood meal resulted in improved ADG and F/G and tended to increase ADFI for the 14 d experiment. The majority of the increase in growth performance occurred during the first week of the trial. In Exp. 2, ADG and AD...

Water-insoluble (particulate) β-glucan was isolated from the cell walls of spent brewer’s yeast using a single-step alkaline treatment. To stabilize β-glucan water suspensions, sonication was successfully applied. Th ree diff erent drying methods were used: air-drying, lyophilization and spray-drying. Air-drying and lyophilization caused β-glucan particles agglomeration and changes of their mic...
