What is a Batch Feed Garbage Disposal?

A garbage disposal eats up all the food substances you throw inside it. It works like a grinding machine inside the chamber. A garbage disposal holds swivel impellers that are sharp blades which spin in a high speed and break up the chunk of foods and make it easy to drain with the sewer line, so the pipes don’t get clogged.

A batch feed garbage disposal simply grinds down the food waste in “batches.” Batch feed disposals come with a stopper. You need to put the waste inside your disposal unit and close it up with the stopper. Then turn the disposal on, and it will start processing the waste. So when the disposal is working, you cannot insert more waste into it. Once it is done working and turned off, you can throw the second batch.

Advantages

  • It is less popular with the users than continuous feed garbage disposals, but not less efficient. You can say it is a safer option. As I said, your disposal will turn on just when you cover it and turn it by yourself. So, there is no chance of accidents (the chances are lower, to say the least). If you have small children who tend to place their hands anywhere in your absence, you should be extra careful with your disposal unit (better to be safe than sorry, right?).
  • The risk of unwanted materials like plastic, paper, glass, metal, your hand jewelry or even cutleries can fall inside the disposal unit. This can cause severe harm to your disposal blades and you may need to replace your whole disposal.

Disadvantages

  • A batch feed disposal is less popular because people think it as a less convenient option. Each time you need to dispose of something, you need to cover it up and turn it on. This can take a bit more time than a continuous feed.
  • As Batch feed disposals are thought as time-consuming, it is less popular in the market. That is the reason why manufacturers make less batch feed disposals. There are a lot of variations available in the continuous feed, but not in the batch. So, you do not have a lot of choice over batch feed garbage disposals.
  • Thinking of convenience and saving time, one may think of filling the disposal with waste for a long time and then grind it up. But it may not be a healthy if one forgets to turn on the disposal and leave it like that overnight, it will begin decomposing and smell like hell. Insects and bacteria also can attack in that case.
  • People with very large families who need lots of trash to dispose of, may not feel it as a convenient option. Because it takes more time than continuous feed to clean all the waste.

What is a Continuous Feed Garbage Disposal?

A continuous feed garbage disposal works continuously. It means that when you turn it on, it runs continuously from then. You can put waste inside it and it will instantly start grinding. It does not come with any stopper. So when the waste is grinding inside the sink, the neck is not covered. You can continuously throw more waste while it is operating without any issues.

Advantages

  • Continuous disposals are very popular among all kinds of users. They are less time consuming, as you don’t need to turn the switch on and off repeatedly.
  • It is a more convenient option to process a huge amount of waste at a time. So, large families with lots of members may find it more useful (or an individual who just cannot stop eating).
  • It’s very easy to operate and maintain. You can instantly throw out whatever waste occurs while cooking or washing dishes, no need to wait to fill up the chamber and then turn it on.
  • Because of the popularity, you will find more options of continuous feed disposals in the market. It comes in many sizes and with different features that can be easier to choose from.

Disadvantages

  • The one disadvantage that you will not find in batch feed disposal, but you will find in continuous is the safety issue. You may always be careful, but there is always a chance of something going accidentally inside your grinding chamber. If something metallic or hard falls inside to the chamber while grinding, it can totally ruin or even break your disposal. So you need to be extra careful with your hands when you have this kind of garbage disposal turned on.

As I have mentioned early, most garbage disposals come with continuous feed and if you would like to review some of them, here you can find some of our guides:


Conclusion

Beside these few points, there isn’t much of a difference between batch feed and continuous feed garbage disposals. Both come with differently powerful motors; both grind the food in the same way. You need to clean up both the disposals after a particular time. Regarding installation and replacements, both are similar. So the difference only lies in the disposing system.

If I am asked, which one is better among Continuous Feed Vs Batch Feed, I’ll say it depends on one’s preference. If safety is more concerned, then the batch feed is better; and if convenience is more important, then continuous feed it is.

I hope that you’ve enjoyed the comparison and that it helped you in some way or another.
