To ensure that Microwave Muffle Furnace The leakage strength shall not exceed the specified value. All flanges and gaskets on the oven cavity and microwave head must be reliably sealed and have good electrical contact. The industrial microwave muffle oven shall not open the microwave power supply without absorption load or the oven door is not locked. The high-efficient energy-saving microwave muffle oven, as its name implies, uses microwave electromagnetic field heating to replace the heating oven of traditional electric heating elements.
