Our Midea rice cooker uses a citrine inner pot. The inner pot is made of 5 layers of composite material to allow for more even heating and stronger heat storage. The exterior adopts the unique honeycomb groove design of the citrine honeycomb liner, which can increase the heating area, and the heat quickly penetrates every grain of rice, making truly sweet and delicious rice! The interior is made of crystal diamond coating, which is non-stick, prevents falling off, and is easier to clean!
