UNLABELLED Spray-dried monoclonal antibody (mAb) powders may offer applications more versatile than the freeze-dried cake, including preparing high-concentration formulations for subcutaneous administration. Published studies on this topic, however, are generally scarce. This study evaluates a pilot-scale spray dryer against a laboratory-scale dryer to spray-dry multiple mAbs in consideration o...

Eighty-one prepubertal beef heifers were used to evaluate effects of used controlled internal drug release (CIDR) insert heating methods on concentrations of progesterone after CIDR insert reinsertion. Heifers were stratified by weight and birth date and then assigned to receive a new CIDR insert (New; n = 10) or 1 of 8 used (7 d prior use) CIDR insert treatments: 1) no processing (Used; n = 10...

No manufactured product plays a more significant role in every area of human activity than paper and paper products. Its importance in everyday life is obvious from its use in recording, storage and dissemination of information. Virtually all writing and printing is done on paper. It is the most widely used wrapping and packaging material, and is important for structural applications. The uses ...

The current study focuses on the life cycle assessment and an economic valuation of a natural convection solar greenhouse dryer in Western Maharashtra, India. Solar Greenhouse Dryer is active device that gains radiation incident to surface along with wind energy, it removes moisture from agricultural yield. combination energy primarily used rural settings; hence, very important analyse environm...

Multi-stage spray drying is an important and widely used unit operation in the production of food powders. In this paper we develop and present a dynamic model of the complete drying process in a multi-stage spray dryer. The dryer is divided into three stages: The spray stage and two fluid bed stages. Each stage is assumed ideally mixed and described by massand energy balances. The model is abl...

The fluidized bed drying principles for drying of tea in Bangladesh is thoroughly studied. The experiments were conducted to determine the drying curve, drying time, drying constant and dynamic equilibrium moisture contents of tea at the Bangladesh Tea Research Institute. Drying of tea in a fluidized bed dryer (Kilburn Vibro Fluid Bed Dryer) takes only 20 min for drying from an initial moisture...

The major drawback of microwave drying is non-uniform heating which may result in low quality dried products. To monitor the electromagnetic field distribution, a simulation process using Finite Element Methods was conducted. Three geometries different sizes were selected as cavity. Analysis variance for index showed that cavity size has significant effect ( p < 0.05) on index. Additionally, it...

DRYER SECTION OF A PAPER MILL M. Berrada, P. Radziszewski, M. E. Elkadiri Department of Applied Sciences, Université du Québec en Abitibi Témiscamingue, Rouyn Noranda, Québec, Canada, J9X 5E4 ABSTRACT This paper presents an application of the Internal Model Controller (IMC) to the heat exchange in a dryer section of paper product industry. A quantitative discussion on numerical control of multi...

Gasification has become an attractive technology that is capable of producing a rich syngas from a range of biomasses and other fuels. This syngas can then be further processed into liquid fuels through Fischer-Tropsch processes to provide an alternative to current fossil fuels or to provide local markets with a competitive fuel. The purpose of this study was to construct a four-inch bench scal...
