Introduction

The garbage disposal (or food waste disposer as they are formally known) is the workhorse of the American kitchen. It reduces landfill use and makes everyday kitchen clean up easy and fast. Generally a disposal is easily repaired and very reliable.

In this product evaluation I'll review the entry product from the InSinkErator Evolution® product line called the InSinkErator Evolution Essential®. The Essential is a powerful 3/4 HP disposal with stainless steel internal components. Let's take a look at what makes this unit a reliable kitchen appliance.

    Features Overview
  • • 40 ounce grinding chamber with stainless steel construction.
  • • Powerful 3/4 HP motor results in less jams and smoother operation and finer pulverization of the food waste.
  • • Significantly quieter operation than standard disposals.
  • Improved waste food grinding technology including multi-stage grinding versus standard single stage grinding.
  • Unit can grind difficult waste food items including chicken bones, fruit rinds and coffee grounds.
  • Six year warranty for parts and labor
  • Excellent overall value for about $200

Disposal Type and Motor Size:

Feed Type
The Evolution Essential is a continuous feed type disposal that turns on and off with a wall switch.

Motor
The disposal uses a powerful 3/4 HP single phase, 120 Volt, 60 Hz motor that draws an average of 8.1 amps and spins at 1725 RPM. It has a manual reset overload button. The motor also has upper & lower bearings that are permanently lubricated to minimize maintenance requirements.

A 3/4 HP motor is on the upper end of what you find in food waste disposals, as they come most commonly in 1/3 HP, 1/2 HP, 3/4 HP and 1 HP. Beyond that you are getting into commercial disposal motor sizes. The higher horsepower rating of the motor results in less jams and smoother operation and finer pulverization of the food waste. That results in less clogged drain lines and less stress on your city's waste water system and better performance with a septic system.

Food Grinding Chamber
This model boasts a fairly large 40 ounce grinding chamber capacity to handle a decent amount of waste food volume. InSinkErator used to have a 50 ounce grinding chamber with their 555ss model but the newer Evolution series has reduced that to 40 ounces when they totally redesigned their grinding technology now called "MultiGrind Technology®". The grind chamber is constructed from stainless steel for better reliability and also has stainless steel grinding components for improved durability. (Less expensive disposals can use a grinding chamber made of glass filled nylon but stainless steel is much preferred).

The new MultiGrind Technology® is a major innovation from the previous 555ss model which used two stainless steel 360° swivel lugs (impellers). This new grinding technology use a proprietary grind-shear ring and two or three stages of waste processing (the Essential model uses two stages, only the top of the line Essential Excel model uses three stages). The three stages shear, shred and grind the waste food. The Insinkerator Evolution Essential uses the grind-shear ring but does not have the tri-action fixed and swivel lug system of the Evolution Excel model for increased grinding.

Noise
Insulated outer shell for reduced noise when in operation. Also anti-vibration tailpipe and sink mounting.

Dimensions
Overall Height: 12-5/8"; Diameter: 8-3/4"

6 year in-home parts and labor

Price
Approximately $200 - $250

Good timing, Member inuit13

My garbage disposal started having problems the other day. There is something stuck in there and it sounds terrible. I was going to start looking into a new one today and VOILA, there is Bob's article on disposals. I have always been leery about how well they actually work. If I have scraps to discard and it is a few days fom garbage pickup, I will throw them in the trash. I have always been afraid I will clog my drains if I ""overuse"" my disposal. Looks like I have nothing to fear. My disposal is 17 yeas old and technology has changed I am buying a new one today!
