The fast spinning blades create heat above 50 degrees Celsius, which breaks down enzymes and nutrients found in fruits and vegetables.
The gentle squeezing and crushing action retains maximum amount of nutrients, as produce is never exposed to heat. This can be double to even three times the amount of centrifugal juicers.
2. Noise Level
Due to the high RPM of the motor, centrifugal juicers tend to be quite loud and disruptive.
The slower process of juice extraction means the motor spins at a lower RPM than centrifugal juicers, resulting in an almost silent juicer.
3. Juices Leafy Greens
Testing proved that less juice was extracted from leafy greens. It resulted in a mousse-like foam and separated the juice.
Cold press juicers are renowned for the quality of juice extracted from leafy greens.
4. Easier Cleaning
As pulp attaches itself to the blade and strainer inside the juicing machine, cleaning can be difficult and there are many bulky parts to clean.
Cold press juicers are easy to clean and take half the time. The user simply pours water down the chute and turns the machine on. Afterwards, simply rinsing with warm water will sufficiently clean the machine
5. Juice Stays Alive for 48-72 Hours
Juice from centrifugal juicers separates when extracted. Juice needs to be drunk immediately as the enzymes and nutrients have been destroyed.
Juice from cold press juicers does not separate when produced. Juice can survive 48-72 hours in the fridge after extraction.
Centrifugal Juicers
Centrifugal juicers are commonly available in retail outlets and are the cheapest type to purchase. These machines initially extract juice by pulverizing fruit and vegetables against a round cutting blade that spins very quickly against a metal strainer. The centrifugal force generated by the spinning motion of the cutting surface separates the juice from the pulp.

Cold Press Juicers
These machines operate via a masticating (chewing) or cold press method to produce a superior juice to their centrifugal counterparts. In contrast to the rough extraction and high speeds of centrifugal juicers, cold press juicers operate at lower speeds and gently compress fruit and vegetables to ‘squeeze’ out their juice. While more costly, their slower and more thorough extraction rates produce a higher-quality juice, and more of it.
