Calcium carbonate is a versatile mineral with diverse industrial applications. Drying is a necessary processing step in preparation of calcium carbonate product. Deep knowledge of drying kinetics is required in order to design an appropriate dryer. The main aim of the present study was to investigate the drying kinetics of calcium carbonate, experimentally. Thirteen empirical correlations with ...

Drying is an important process in the generation of wood products, as it increases quality final products; however, influenced by various anatomical characteristics. The aim this study was to evaluate influence anatomy on drying Parapiptadenia rigida (Benth.) Brenan, Peltophorum dubium (Spreng.) Taub., Eucalyptus grandis W. Hill × urophylla S.T. Blake (hybrid), and Schizolobium parahyba (Vell.)...

the objective of this study was to examine the effects of the fluidized-bed drying me-thod on the final quality of two varieties of iranian rice, medium- and long grain. the re-sults were compared to that of paddy drying using a traditional method. rough rice was treated in the fluidized bed drier at 140ºc for 2 minutes. similar samples were dried for 8-10 hrs by the traditional method. dried s...

simulation of rough rice drying is one of the proper methods for predicting moisture distribution in the product, and throughout the process of drying. the drying process must be well understood and controlled so that design guidelines which reduce or minimize drying damage to rough rice can be established and improved. therefore, an accurate understanding and description of the drying mechanis...

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

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...

The conventional methods of drying Chinese wolfberry fruits cause loss of active ingredients and the drying time is very long. In order to explore and investigate the new method of drying Chinese wolfberry fruits, electrohydrodynamic (EHD) drying system was used to drying for Chinese wolfberry fruits with a multiple needle-to-plate electrode on five levels alternating voltage at 0, 20, 24, 28 a...
