Preethi Steele Supreme Mixer Grinder
Indian mixer grinder with 100% stainless steel jars - a powerful full-size blend/grind path where the vessel and blades are steel, not Tritan. Caveat: 230V, needs a voltage converter in the US.
The verdict: Minimal plastic contact
The blending and grinding jars are 100% stainless steel and the blades are steel, so the high-friction, high-heat blend wall - the part of a blender most likely to shed microplastics - is metal rather than Tritan/polycarbonate. What keeps it out of the cleaner tiers is the plastic in the sealing path: the jar lids are plastic, there is a gasket at the lid, and the jar base has a plastic coupler where it locks onto the motor. Food mostly meets steel, with plastic contact limited to the lid and seal area - meaningfully less plastic than an all-Tritan jar, but not none.

A South-Indian-style mixer grinder: a powerful motor base that drives interchangeable stainless steel jars for wet grinding, dry grinding, and blending, typically a four-jar set (1.5L / 1.0L / 0.4L plus a chutney jar). It is shaped for grinding spices, batters, and pulses more than for large smoothie batches. The practical catch for US buyers: these are 230V/50Hz units built for the Indian grid.
Pros
- 100% stainless steel jars and blades - the blend wall is steel, not Tritan
- Genuinely powerful for grinding tough spices, batters, and pulses
- Steel jars are durable and don't haze or shed like plastic jars
Cons
- 230V/50Hz - needs a step-up voltage converter (and tolerance for 50Hz) to run in the US
- Lids, gaskets, and jar-base coupler are still plastic/silicone
- Opaque steel jars mean you can't watch the blend
- Loud, and shaped for grinding more than for large smoothie batches
Notes
- Some Preethi models are sold in US 110V versions on Amazon (e.g. the Nitro and Eco lines) - if you want to avoid a converter, look specifically for a US-voltage listing
