Types of Juicers

There are several different commercial juicers currently available for the extraction of juice from vegetables or fruit. These devices are generally powered by an electric motor and employ filters to remove excess solids (pulp) from the juice. Some allow for continuous juicing (automatic pulp expulsion) while some do not and must be occasionally shut down for manual removal of pulp. There are basically three primary types of commercial juicers: masticating, auger, and centrifugal.

The Champion Juicer is the only true masticating juicer on the market - it is the only juicer that cuts and chews the foodstuff.  It has a single horizontal cutter that rotates at high speed, about 1,725 RPM.  The cutter has saw tooth cutting blades at one end and an auger at the other end.  First, the blade part of the cutter (the cutting section) grinds the foodstuff to be processed.  Next, a combination of centrifugal force, compression, and gravity is used to expel the juice out the bottom of the housing.  The front part of the cutter (the auger section) propels the pulp forward and out the front of the housing.  The processing time during juicing is several seconds, which results in a richer juice with more robust color, flavor, and nutrient content.  Due to the high rotational speed of the cutter, the grinding action of the saw tooth blades, and the longer processing time, the Champion Juicer’s homogenizing capability is superior to most of its slow speed competition.  Products produced such as nut butters, frozen fruit sorbets and baby foods are unsurpassed.  To juice wheatgrass and other fibrous greens the Champion Juicer utilizes a Greens Attachment.

Masticating means to chew, to grind or knead into a pulp.  Masticating juicers use high speed rotation and cutting teeth to grind or chew the material to be processed (foodstuff) to a fine consistency. 

Auger type juicers operate at low speeds, typically from 80 to 100 revolutions per minute (RPM).  Auger juicers consist of the single auger types (horizontal or vertical auger orientation) and the twin auger types.Single Auger

Single Auger juicers
A gearbox is used to achieve the low speed and the additional torque required during processing.  The auger juicers vary in their shapes, orientation of auger (horizontal or vertical), the arrangement of their ribs and grooves, the angle of the ribs, and the depth of the grooves.  The foodstuff is pushed against the rotating auger, where it gets chopped or torn into smaller pieces.  The rotating auger forces the chopped foodstuff forward or down where it gets pressed against a screened enclosure for extraction of the juice.  These juicers are best suited for juicing leafy greens and soft materials, such as fruit.  Juicing of hard vegetables, such as carrots or beets, is slow and cumbersome, due to the chopping or tearing nature during processing.   These juicers are inadequate for homogenizing due to their low speed operation. 

Twin Auger juicers
Utilize two augers at the same time.  The two augers mesh together by rotating in opposite directions to first cut the foodstuff andTwin Auger then squeeze the chopped foodstuff between the augers for extraction of the juice.  These dual auger juicers are best suited for soft materials, leafy greens and wheatgrass.  Considerable force is required when introducing hard materials between the augers, due to the fine auger grooves.  Due to this and the low auger rotational speed, juicing of hard vegetables, such as carrots or beets, is slow and cumbersome.  These juicers are inadequate for homogenizing due to their low speed operation. 

Centrifugal juicers have a rotating, horizontal grating disk that cuts the foodstuff to be juiced and then use centrifugal force to extract the juice from the solids.  Centrifugal juicers operate at about 3600 RPM in order to produce the centrifugal force needed to extract the juice.  This type of juicer processes the foodstuff for a very short period of time, typically less than one second.  Due to this short processing time, the juice tends to be more watery than the juice from most other juicer types.  Centrifugal juicers are best suited for juicing of vegetables and fruit, but cannot juice greens such as wheatgrass.  They do not mix or shred, and cannot homogenize. 

The difference between a centrifugal juicer and a masticating juicer is like night and day.

Centrifugal juicers work at high speeds, tend to be noisy and while a centrifugal juicer may be able to juice the rind of a pineapple more efficiently, in most situations, the action of a masticating juicer allows you to juice more vegetables with greater efficiency. A masticating juicer tends to be a lot more quiet, less messy and easier to clean.
