Kinds and features of grinders

Speaking about how it is better to choose a food waste chopper, you need to consider the types of these devices:

  1. Mechanical (hydraulic choppers), equipped with several knives, which are rotated by the water flowing from the tap. If the water pressure is weak (less than 2.5 atm.), Then the device may stop functioning. Mechanical dispensers are considered safer than electrical ones.
  2. Models with electric drive, which today are the most popular. Grinding occurs with an electric or induction motor. There are no knives in the construction, it is equipped with a system of hammers, a disk, and rings, it is started by the user as needed with the help of a button.

Mechanical shredders are more expensive than electric ones, due to their versatility. After studying the reviews and recommendations of manufacturers, it can be understood that they are not recommended for use in homes where there are children. The fact is that the rotation of the knives is stopped only if an element made of metal or durable glass enters the chamber, which simply blocks the work.

Opening hours and installation

Such devices are installed under the kitchen sink, embedded directly into the sink. The recommended diameter of the drain hole is 90 mm. If the hole has smaller dimensions, then the expander adapter is used, which should be installed by a professional plumber.

The average grinding time is no more than 20 seconds, which depends on the power and throughput. Basically, high-quality sink grinders are made of stainless steel, which is resistant to corrosion, deformation, and has a long operating period. Less commonly used polycarbonate, which also has decent performance.

What can and what should not be thrown into the disposer?

The device is capable of crushing the following types of waste practically into crumb (size 3-4 mm):

  • cleaning, slices of vegetables and fruits;
  • organic food residues;
  • small soft bones, such as chicken or fish. It is noteworthy that manufacturers recommend throwing small bones into shredders, which contributes to the system self-cleaning;
  • inorganic waste: napkins, pieces of toothpicks, paper towels;
  • pieces of pasta, cereal, bread.

The kitchen grinder cannot be used for the following types of organic and inorganic waste:

  • pieces of glass, hard paper;
  • large bones, such as pork or beef;
  • onion peel;
  • corn cobs;
  • fish scales, although grinding of a small amount is permissible;
  • textiles, sponges for washing dishes, thread, hair or wool;
  • plastic bags;
  • metal elements.

If you try to fill the chamber with prohibited types of waste, then the fuse trips the cycle. Husk, scales, threads clog the displacer, as a result of which it can fail.

Tip!  If not processed waste remains in the kitchen grinder, you can fill the sink with water by adding a glass of soda or 2 glasses of salt to the liquid. After that, you need to open and turn on the device. Soda or saline solution will clean it well!

Which food waste chopper to choose? Decoding of the main characteristics

Rotational speed

Speaking about how to choose a food waste chopper, it is necessary to mention the rotation speed. This characteristic depends on the electric motor, in the hydraulic – on the water pressure. It can range from 1425 to 4000 revolutions per minute. For domestic use, models with speeds from 1425 to 2700 rpm are suitable.

Higher power makes it possible to chop nutshell, large bones and other types of solid organic waste. Such equipment is used mainly for restaurants and cafes, so its cost is very high.

Water and fluid consumption

Water consumption, equipment size, and performance directly depend on the volume of the crushing chamber. In household devices, it can be 700-1180 ml, choosing, be sure to pay attention to this characteristic.

Any model operates with a continuous supply of hot or cold water. When using this type of equipment, water consumption per person rises by an average of 3 liters. If a family of 3 people uses a dispenser, then the increase in fluid consumption is about 2.5-3% per day.

Power consumption

The characteristic is relevant for electric dispensers. Standard power ranges from 375-930 watts. For domestic use, it is better to choose medium power devices (520 W). If the family consists of 4 or more people, then consider buying a model with a capacity of up to 750 watts. All hotel products are intended for commercial use.

Noise level

Electric food waste dispensers are noisier than mechanical ones, due to the continuous operation of the electric motor and the lack of cutting knives. The maximum noise level is 70 dB, but only when grinding too hard or large waste (bones, nutshell, and others). Some models are supplemented with 100% or partial sound insulation. The sounds that such equipment makes are reminiscent of noise during the work cycle of a coffee grinder.


Grinders have an average height from 310 to 440 mm, width – from 120 to 270 mm, the weight of the equipment reaches 7 kg. When choosing a suitable product, perform measurements of the space under the sink; after installation, there should be a reserve of 5-7 cm, necessary for maintenance.
