Cork sterilization and decontamination process employing microwaves

摘要

The bulk cork or corks, is/are subjected to microwave radiation at a power of 2-1000 W/kg over an interval of 5-10 min. Preferred features: The power is 50-200 W/kg, in a conveyor oven operating continuously. Water content is reduced from 12-15 wt% to 6-10 wt%. Composite cork in manufacture, is submitted to microwave radiation, for more rapid binder polymerization and setting. In addition, stabilization of adhesive between natural cork sections is accelerated.
