We’ve covered some of the technical components that are spinning inside a humble garbage disposer, but the real action takes place in the grinding system. At the same time, the tech challenge is how to make this operate as quietly as possible!
The high-end units will use multiple grinding wheels to crush food waste to a pulp. They also use special materials and baffles to reduce the sound.
Take, for example, one of the best-selling models, the InSinkErator Evolution Excel, which is designed for busy kitchens and has multiple grinding stages and a special noise-reduction system.
(As an aside, if you are looking for a new unit and are confused with the choice, take a look at this review site that compares features from the best garbage disposal units and provides a useful comparison chart.)
A key selling point of the Excel is its high-end grinding system: other models might include a single grinding setup (with one set of grinding wheels), but the Excel includes a 3-stage grinding system to crush and pulp even the toughest chicken bones.
This model also includes what InSinkErator say is a unique sound-reduction technology that cuts the noise from the unit to acceptable levels so you can still hear normal conversation whilst it’s running. This is thanks to the special sound-reduction baffles and low-friction materials such as nylon bushes, that together make up the unique SoundSeal system.
