Microwave Drying of Wood Strands
Characteristics of microwave drying of wood strands with different initial moisture contents and geometries were investigated using a commercial 10 small microwave oven under different power inputs. Temperature and moisture changes along with the drying efficiency were examined at different drying scenar ios. Extractives were analyzed using gas chromatography=mass spectrometry (GC=MS). The res...
متن کاملMicrowave Drying of Paper Documents
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...
متن کاملSpectroscopic studies of wood-drying processes.
By the use of wavelength-modulation diode laser spectroscopy, water vapor and oxygen are detected in scattering media nonintrusively, at 980 nm and 760 nm, respectively. The technique demonstrated is based on the fact that free gases have extremely sharp absorption structures in comparison with the broad features of bulk material. Water vapor and oxygen measurements have been performed during t...
متن کاملApplication of Microwave in Food Drying
Microwave is the machine, which is very helpful for the food sector. The modern age of life as well as the increasing number of working women requires simplified routines and standardization of foods with lesser preparation time and convenience in usage. The demands of the consumers are the real factor for the success or failure of any food items in the present scenario. The increasing consumer...
متن کاملPredicting Thickness Swelling of Hot-pressed Wood Strands
Strand board can be manufactured from sawmill residues, branches, and crown wood left in the forest. The thickness swelling of these residues is quite different from that of mature wood and can have a negative effect on the physical and strength properties of strand board. A mixture of these materials and pressing conditions can be optimized by assessing thickness swelling of wood strands after...
