What is the microwave drying and heating?
Microwave Drying relies on additional energy being supplied that’s preferentially absorbed by the solvents in the process to enhance evaporation.Microwaves are a form of electromagnetic energy (300 Mhz–300 GHz),generated by magnetrons under the combined force of perpendicular electric and magnetic fields.In the pharmaceutical industry,the most common frequency used is 2450 MHz,because of the advantages that this frequency offers in conjunction with a vacuum;
Microwave Heating is a direct heating method.In the rapidly alternating electric field generated by microwaves,polar materials orient and reorient themselves according to the direction of the field.The rapid changes in the field — at 2450 MHz,the orientation of the field changes 2450 million times per second — cause rapid molecular reorientation,resulting in friction and heat.Different materials have different properties when exposed to microwaves,depending on the extent of energy absorption,which is characterized by the loss factor.Given the characteristics of the materials commonly used in pharmaceutical production,microwave energy is well suited for drying pharmaceutical formulations.The liquids most frequently used in wet granulation (water and alcohol) have much higher loss factors than the other standard wet granulation ingredients (lactose,corn starch, for example),leading to higher microwave energy absorption and the preferential heating of these liquids.
