Why can industrial microwaves have metal in them
Industrial microwaves safely use metal components (e.g., stirrers, conveyor belts) because they operate at carefully tuned frequencies (915MHz or 2.45GHz) where metal reflects rather than absorbs microwaves, preventing arcing. Their larger cavities (30-100L vs. home 20L) distribute energy evenly, while rounded edges and grounded shielding minimize hotspots. Unlike home microwaves, they incorporate faraday cage principles […]
