Classic Rice Cooker
One of the rare electric cookers with both an uncoated clad-stainless inner pot AND a stainless steel inner lid, so neither the rice nor the condensing steam touches plastic or coating.
Plastic-free verdict: No-contact plastic
The differentiator: not only is the inner pot uncoated multi-layer clad stainless (no PTFE, no ceramic coating), but the detachable inner lid that steam condenses on and drips back from is stainless steel too - the part that is plastic on nearly every other electric cooker. Plastic is limited to the outer housing, control panel, and handles, none of which touch the rice or the steam path. No visible silicone gasket in the food path.

A Taiwanese electric rice cooker built around Buffalo's patented clad stainless inner pot - multiple bonded stainless layers with no nonstick or ceramic coating - paired with a stainless steel inner lid and a stainless steam vent. That combination is what sets it apart: on most "stainless" cookers the inner pot may be steel but the inner lid the steam recondenses on is plastic, dripping plastic-contacted water back into the rice. Here that surface is steel. Auto keep-warm is included, which is exactly the long-dwell scenario where a plastic inner lid would matter. Rice can stick without a little fat and the right water ratio - the trade-off for no coating.
Pros
- Uncoated clad-stainless inner pot - no PTFE or ceramic coating
- Stainless steel inner lid, so condensing steam never touches plastic
- Detachable stainless steam vent, easy to clean
- Built to last 10+ years; 3-year inner-pot warranty
Cons
- Rice sticks more than nonstick; needs correct water ratio / a little oil
- Basic controls - no fuzzy-logic or induction programs
- Heavier and pricier than a budget cooker
- Uncoated steel takes more scrubbing
