How to choose a kitchen food waste disposer: tips and best disposer models


The dis­pos­er is a food waste grinder that solves the prob­lem of unpleas­ant odors that occur due to clog­ging of the sew­er with food residues. This device is con­ve­nient for use in every­day life, but it should be cho­sen based on cer­tain cri­te­ria, and then the device will work prop­er­ly for a long time.


The main task of the dis­pos­er is to grind veg­eta­bles, fruits, and oth­er food prod­ucts, so that they are freely washed off with water, with­out caus­ing deposits and an unpleas­ant odor. The choice of high-qual­i­ty equip­ment should always be based on its high func­tion­al­i­ty, since dif­fer­ent types of devices oper­ate on the same prin­ci­ple. Waste is placed in the stor­age tank in the form of clean­ings and trim­mings, which are processed into crushed slur­ry.

There are two mech­a­nisms of action:

  1. Inside the cylin­der with grooves on the walls is placed a cir­cu­lar block with pro­tru­sions around the cir­cum­fer­ence. Dur­ing rota­tion, the waste enters the grooves and is exposed to pro­tru­sions that tear them into small pieces under the action of cen­trifu­gal force. As a result, the recy­cled waste is grad­u­al­ly crushed, mov­ing to the edges and “leav­ing” the stor­age cham­ber.
  2. The sec­ond option does not pro­vide for a dri­ve, since grind­ing occurs with the help of knives mount­ed on shafts rotat­ing towards each oth­er. Garbage falls into the groove formed by the slots of the shafts, being crushed by knife blades.

Dis­pos­er with­out accu­mu­la­tor is more pro­duc­tive and pro­vides bet­ter grind­ing. A pos­i­tive fea­ture of the tech­nique is that the knives remain sharp for a long time.

When choos­ing a device, you need to pay atten­tion to the fact that it:

  • cre­ate as lit­tle noise as pos­si­ble;
  • was safe to use;
  • eas­i­ly repaired;
  • did not need spe­cial, ser­vice main­te­nance.

It is impor­tant that the unit can work in var­i­ous con­di­tions, and be min­i­mal­ly prone to fail­ure. The dis­penser must be of high qual­i­ty and afford­able.

Since the equip­ment is placed under the kitchen sink and con­nect­ed to the sew­er, the size of the grinder and the require­ments for its instal­la­tion are of no small impor­tance — a cer­tain length of the sew­er pipe, a pipe for sup­ply­ing waste to the cham­ber, a sep­a­rate out­let for the start but­ton of elec­tri­cal devices.

Placement of the dispenser under the sink

For those who decide to pur­chase equip­ment, the main thing is to decide on the vol­ume of the cylin­der. For a small fam­i­ly, you can choose a com­pact device that will prop­er­ly cope with the amount of incom­ing garbage. In this case, you should start from how many peo­ple need to be served. In addi­tion, the qual­i­ty of the waste also plays a role. In this regard, the types of devices that can be used for recy­cling should be con­sid­ered.

Criterias of choice

Con­sid­er­ing the grow­ing demand in the dis­penser mar­ket, each fam­i­ly needs an opti­mal­ly suit­able mod­el with a cer­tain set of para­me­ters.


Its func­tion­al pro­duc­tiv­i­ty depends on the pow­er val­ues ​​— grind­ing waste of dif­fer­ent con­sis­ten­cy. The opti­mal para­me­ter is con­sid­ered to be 500 W and above. Although there are mod­i­fi­ca­tions with low­er rates — 370 and 475 W, they can­not cope with sol­id food waste. Such mod­els are designed for veg­etable and fruit cut­tings of medi­um den­si­ty.

Devices with a pow­er of 1200–1300 W are capa­ble of pro­cess­ing, in fact, all types of food residues, includ­ing large bones or nut­shells.

It is impor­tant to choose ener­gy-sav­ing shred­der mod­els that allow you to use as lit­tle elec­tric­i­ty as pos­si­ble. It is clear that it is not advis­able to buy a device with high pow­er, which con­sumes a lot of elec­tric­i­ty, if the fam­i­ly is small, and the dis­penser is used occa­sion­al­ly.

You can cal­cu­late the pow­er of a suit­able unit from an aver­age need of 100 W per per­son. On aver­age, for a fam­i­ly of 4 peo­ple, a device of 400–500 watts is suit­able.

Cylinder volume

The size of the work­ing cham­ber depends on the pow­er of the device and can vary from 700 ml to 1.5 liters. Its vol­ume should be large enough, but this size always depends on the free space under the sink. If there is not much space, you can lim­it your­self to a capac­i­ty of 800–900 ml.

An impres­sive vol­ume of the cylin­der — 1200–1500 ml will be need­ed in a large fam­i­ly, where they often cook, and a large amount of food waste accu­mu­lates.

In addi­tion, when buy­ing, you should make sure that the body mate­r­i­al is made of anti-cor­ro­sion mate­r­i­al. In most mod­els, the cylin­der, as well as its crush­ing parts, are made of stain­less steel.

Waste disposer under the sink

Before buy­ing, it makes sense to mea­sure the dimen­sions of the sink and the space under it.

Disk rotation speed

The speed of the dis­pos­er depends on the num­ber of rev­o­lu­tions of the disc. The most effec­tive for pro­cess­ing is an indi­ca­tor of 1400 rpm. Some devices have an adjust­ment for this speed or sev­er­al dif­fer­ent modes. In gen­er­al, regard­ing the speed of rota­tion of disks, the high­er its val­ues, the bet­ter.

For mechan­i­cal grinders, this para­me­ter com­plete­ly depends on the pres­sure of water in the water sup­ply.

Con­clu­sion: when choos­ing, you need to start from the num­ber of peo­ple liv­ing, the total vol­ume of waste and their qual­i­ty, as well as from the pres­sure in the water sup­ply sys­tem when an elec­tri­cal or mechan­i­cal device is select­ed.

Types of kitchen grinders

The chop­ping attach­ment can be dri­ven hydrauli­cal­ly or elec­tri­cal­ly. There­fore, there are two types of equip­ment — man­u­al and elec­tric.

Electric dispensers

Such mod­els have their advan­tages:

  • They have suf­fi­cient pow­er.
  • They con­sume extreme­ly lit­tle elec­tric­i­ty.
  • Mod­ern mod­els are almost silent.
  • The use of elec­tric dis­pensers is sim­ple.
  • Elec­tri­cal appli­ances are safe, as there is no access to the inner cham­ber, there are pneu­mat­ic safe­ty switch­es, when prop­er­ly installed, the start but­ton works with one touch.
  • Since such devices are con­nect­ed to the net­work through a relay, when jammed, the equip­ment turns off on its own — you just need to remove the bot­tom cov­er and remove the for­eign object that inter­feres with work.
  • Com­pared to hydraulic devices, elec­tric mod­els are more reli­able, espe­cial­ly since they have a long war­ran­ty peri­od (up to 5 years).

The nec­es­sary con­di­tions for cor­rect oper­a­tion are com­pli­ance with safe­ty pre­cau­tions, clear­ly spelled out in the instruc­tions, and the pres­ence of cold water.

The dis­ad­van­tages of elec­tri­cal devices include:

  • aver­age noise lev­el, but usu­al­ly, it is pro­duced by out­dat­ed mod­i­fi­ca­tions;
  • lack of cold water can lead to fail­ure and shut­down due to over­heat­ing;
  • elec­tric mod­els, despite their pow­er, may not be able to cope with large waste, for exam­ple, banana peels, large bones;
  • the unit will not work if there are fre­quent pow­er out­ages in the house or apart­ment — in such sit­u­a­tions it is bet­ter to buy a mechan­i­cal mod­el.

As you can see from the func­tion­al­i­ty overview, such dis­posers are suit­able for a large amount of waste — they will always be use­ful in a large fam­i­ly, but you will need to ensure that large debris does not get into the tank.

To improve the per­for­mance of the elec­tric mod­el and clean the walls of the stor­age cham­ber, man­u­fac­tur­ers advise peri­od­i­cal­ly pass­ing chick­en bones through it.

Mechanical dispensers

This tech­nique is unpre­ten­tious and can work in any con­di­tions, even in the absence of elec­tric­i­ty. It works from water, as soon as it pass­es through the device, the unit starts pro­cess­ing.

The undoubt­ed advan­tages of such devices:

Noise­less­ness at work;

  • high pro­duc­tiv­i­ty — the equip­ment pro­duc­tive­ly grinds the peel, veg­etable peel­ings, chick­en bones, nut­shells;
  • the tech­nique is safe for hands, as the knives are locat­ed at some dis­tance from the drain hole of the sink;
  • when hit by large, sol­id objects, the hydraulic sys­tem is imme­di­ate­ly blocked.

How­ev­er, man­u­al mod­els also have dis­ad­van­tages:

  • Sol­id waste may not be recy­cled, as the pow­er of the hydraulics is infe­ri­or to the pow­er of the elec­tri­cal devices.
  • When choos­ing a man­u­al mod­i­fi­ca­tion, you need to care­ful­ly study the instruc­tions, it is bet­ter to pur­chase more mod­ern dis­pensers — they are safer. We must not for­get that the start-up of equip­ment is car­ried out with a stream of water, and not by press­ing a but­ton, so you should use such a chop­per care­ful­ly.

Mechan­i­cal devices are unlike­ly to be suit­able for fam­i­lies liv­ing on the upper floors of hous­es, since a weak water pres­sure will not be able to pro­vide the nec­es­sary pow­er to process garbage.

Dif­fer­ent types of dis­pensers dif­fer great­ly in their cost. If hydraulic shred­ders can be pur­chased at a price of 8 to 15 thou­sand rubles, then an elec­tri­cian is more expen­sive — from 15 thou­sand rubles and more. In some sit­u­a­tions, with fre­quent pow­er out­ages, it makes sense to buy high-qual­i­ty man­u­al equip­ment that costs the same as a cheap elec­tric mod­el.

In fact, the choice is to choose a man­u­al or elec­tric unit. But, in addi­tion, you can give pref­er­ence to dif­fer­ent types of load­ing — batch or con­tin­u­ous. In a fam­i­ly with elder­ly peo­ple and chil­dren, por­tion dis­pensers are more con­ve­nient and safer.

Recommendations for choosing dispensers

The choice of both man­u­al and elec­tric mod­els comes down to cri­te­ria such as:

  1. Water pres­sure — if it is low (about 4 bar), then it is bet­ter to buy equip­ment pow­ered by the mains.
  2. It is advis­able to pur­chase elec­tric mod­els with engine pro­tec­tion and a spe­cial reverse for auto­mat­ic clean­ing of inter­nal, work­ing sur­faces, it is good if the dis­penser has an anti-cor­ro­sion coat­ing.
  3. If the grinder is pur­chased for the pur­pose of pro­cess­ing clean­ings, as well as sol­id waste in the form of bones and veins, then you should focus on increased pow­er — up to 1200 W.
  4. The time of grind­ing food debris depends on the speed of rota­tion of the shafts, so it is advis­able to choose mod­els with speed con­trol of about 1200–1400 rpm.
  5. The dimen­sions of the equip­ment should be select­ed tak­ing into account the free place­ment in the space under the sink, in addi­tion, you will need space to access the dis­pos­er.

Pay atten­tion to the con­fig­u­ra­tion of the kitchen sink and the dimen­sions of the drain. Mis­match with the para­me­ters of the dis­pos­er may require an increase in the diam­e­ter of the drain hole. This will not be dif­fi­cult with a stain­less steel sink, but will be dif­fi­cult in all oth­er cas­es. You can read more about con­nect­ing food waste dis­posers here.

Despite the fact that mod­ern mod­els are designed for trou­ble-free oper­a­tion for 10–15 years, they require care and peri­od­ic clean­ing using spe­cial prod­ucts. Care must be tak­en to ensure that for­eign objects and hair do not get into the device. This is the only way to ensure a long ser­vice life of use­ful equip­ment.
