Types of Garbage Disposal: Electric with Continuous Feed vs. Batch Feed

Types of Garbage Disposal: Electric with Continuous Feed vs. Batch FeedIn this article we decided to spread a word about different types of garbage disposals. There two main kinds of them: electric disposals and hydraulic (mechanical) disposers. Electric garbage disposers are more convenient and most used at residential markets.

Feel free to ask your questions and write your thoughts about this article in comments.

Electric Garbage Disposals Types

By name, it is easy to guess that such devices work from the electric network. As soon as the user presses the start button, the engine turns on, which drives the entire mechanism of crushing waste. These are powerful, reliable and durable devices that are more popular than hydraulic counterparts.

According to the principle of operation, garbage disposers are divided into two types:

With continuous feed

Such a disposal grinds waste during the entire period while you, for example, wash the dishes. All that is required of you is to turn on cold water, press the button of the device, throw waste into the drain hole of the sink and, after the sound of the engine running “idling”, the dishes are washed and the waste no longer comes in, just turn off the chopper. Then you need to flush the sewer for 10 seconds and you can repeat the operation again. Convenient and simple.

With batch feed

In this case, a certain portion of the waste is first accumulated in the grinder, and only after that crushing begins. If necessary, after grinding the first part of the waste, you can repeat the process. This is not very convenient, so this type of disposers is already difficult to find on sale. They are also more expensive.

The advantages of electric disposers include:

  • high power and productivity
  • safety and simplicity
  • durability. The service life, according to most manufacturers, is more than 25 years
  • the device turns off independently, as it is connected to the relay. It is enough for the user to remove the cover, find the object that interfered with work, and remove it.


  • noise, but most modern models are not very noisy when working
  • some large wastes are beyond the power of an electrical appliance, even despite its high power;
  • in areas with power outages and frequent power surges, such a device will cause more problems than amenities.
  • It is impossible to use such a disposer without water, it cools the engine, contributes to easier grinding and promotion of waste through the sewer.

Useful advice!
If you want to avoid the spread of unpleasant odors from the drain of the sink and prevent the growth of bacteria, then you should pay attention to the disposers with a special antibacterial coating inside the case. Check our best garbage disposals reviews, it will help you with that.

Hydraulic (mechanical) garbage disposal type

This is a simple and reliable equipment that does not require a network connection. The grinding mechanism comes into motion under the influence of water pressure. If there is water there is a process, there is no water everything froze, i.e. Disposer will always work when there is a flow of water. Unfortunately, this type of disposer is discontinued and very hard to find.


  • reliability and unpretentiousness. With frequent power outages, this is the best option
  • energy savings
  • security
  • sufficient performance
  • large and solid wastes immediately block the system, preventing it from breaking when trying to grind a “dangerous” product
  • noiselessness


  • low water pressure will not be able to activate the system. If you live on the upper floors and the water pressure is much lower than the norm (the norm is 4 bar), then difficulties may arise
  • solid waste is more difficult to process than in electric models
  • the disposer turns on immediately when the water is turned on, and this is very important to consider when choosing a model and further operation

It is difficult to say unequivocally which food waste disposer is better, electric or hydraulic. The choice is best built on the characteristics of the home and your own needs. If there is no interruption in power supply, then you can take a powerful electric dispenser and no longer think about anything.
