Centrifugal Juicers Review

Possibly the oldest type of juicers, Centrifugal juicers are commonly used for their speed and convenience of operation. They are slightly less efficient than masticating juicers, and consequently more affordable. The cutting design is more robust than the auger in masticating juicers. It is for this reason that centrifugal juicers have large feeding chutes that allow foods to be entered whole (without dicing them first).

Design

Centrifugal juicers have an upright design. The feeding chute is located at the top, with a cutting disc/blade below it. This disc/blade is typically located at the base of the strainer basket, although some models have it just below the chute. The strainer basket has minute pores on the sides that allow juice to pass through but retain the seeds and pulp.

How it works

Breville BJE510XL Ikon 900 Watt Variable Speed Juice ExtractorFood is entered through the chute. It hits the cutting disc (which spins at a high speed) and is shredded into small pieces. These pieces are then spun at high speeds in the filter basket, and the centrifugal force causes the juice to escape through the pores and pour out of a spout located in the front. The higher the speed, the more the extraction. The residual pulp stays in the strainer basket and can be removed manually once the juicing is finished.

The mechanism is similar to the the drier in a washing machine. The washed clothes are spun around at high speeds in the drying basket, which has holes on the sides. Most of the water escapes out of them, leaving the clothes only slightly moist.

Continuous pulp ejection

The older centrifugal juicers has strainer baskets with vertical walls. This meant that the pulp had no outlet and would collect in the basket itself. As a result, it had to be manually removed after every couple of cycles. A revolutionary self-cleaning design was incorporated to eliminate this problem. In it, the walls of the strainer basket are slanted outwards. As the pulp spins around, it starts rising slowly and is ultimately ejected out the top of the basket, into a receptacle. This ensures that no pulp is collected at the base, allowing for continuous juicing. Most modern centrifugal juicers feature large-capacity pulp-collectors that don’t need to be emptied frequently.

The bad

Centrifugal juicers are generally not effective with leafy greens such as spinach, parsley, kale or wheatgrass. Such foods require the slow moving auger-style mechanism of masticating juicers. The fast spinning action of a centrifugal juicer will eject the greens out without first juicing them thoroughly.
They are less efficient than masticating juicers, though only slightly. The residual pulp is not as dry, and may need to be fed in again for maximum extraction.
Since the contents are spun around at a high speed (rpm), the juice gets aerated, leading to some oxidation (visible as a layer of froth). This oxidation of the juice is very harmful as it reduces the shelf-life of the juice as well as its nutritional content. For this reason, most users of centrifugal juicers consume the juice right after making it.
Because of the high speeds involved (up to 15000 rpm), centrifugal juicers are noisier than than their masticating counterparts.
Some health specialists have criticized the centrifugal design for unintentionally producing too much heat (caused by friction between the rotating parts). This heat can kill many essential nutrients and enzymes present in the juice.

The good

Centrifugal juicers are fast in operation. The spinning assembly can deliver a fresh glass of juice within seconds.
The automatic pulp ejection feature has made them easier to clean than ever before.
They are highly affordable and the good ones start at around $100.
Many centrifugal juicers feature multiple-speed controls, that can be adjusted according to the type of food entered.
The feeding chute is wider than in a masticating juicer and can have a diameter of up to 3”. This eliminates the need to chop your produce before entering it in the juicer.
They work well with most hard and soft fruit and vegetables.
