Batch Feed vs Continuous Feed Garbage Disposals

There are two types of mechanism used in garbage disposals – batch feed and continuous feed units. Most disposers are continuous feed – and, as a result, these are the most popular type fitted in households. So what’s the difference?

Batch feed garbage disposals: you load up the food waste (pushing it into the disposer chamber through the plughole) and then fit a cover to the plughole and switch on the unit to grind and crush the food waste.

Continuous feed units: you switch on the unit, turn on the faucet, then push the food waste into the plughole and the unit grinds the food waste.

  • Pros of a continuous feed garbage disposal – it’s quick and easy to use and is the most commonly installed in households.
  • Cons of a continuous feed disposer – there’s no cover to the unit so it’s possible for non-waste items to fall into the grinding chamber (eg a fork or spoon). Worse, if you have kids there’s a chance it could prove a danger.

For more information about batch feed models (vs continuous feed) and would like to find out more about the advantages of the different systems, I’ll describe the mechanics and why you should choose a particular feed system.

So what’s different about a batch feed disposer? The main difference is that it will not start working until you click into place the cover (that normally fits into the plughole in your sink). This is a great safety feature that means it’s harder to hurt yourself – good with kids! – and can avoid damaging the unit by accidentally trying to grind a fork or spoon!

To use a batch disposer, you fill the garbage disposal’s chamber with your kitchen waste by pushing the food waste into the plughole in your sink. You then run the tap to provide water that will help flush the waste through the disposer and fit the lid into the plughole, which switches on the disposer motor and starts the grinding process.
