  The story of the first electric juicers began in 1948. At that time, several companies decided to try to get the juice using a centrifuge. They have developed several models of centrifuges. The juices obtained by applying the power method (pressure, press screws to the grinder and others), were dense mass of solid particles from the product. Those juicers had an electric motor, but the most effective juicer was invented by Urs Pfluger in 1955.

  Since 1955, the firm ROTEL, under the leadership of Mr. Urs Pfluger, began to actively work on improving the juicer. They broke the work into several stages. This was due to the fact that they produced a particular party juicers and then worked with clients who used them and gave their feedback.
  
  The main problem was that when the extractor has a large vibration sieve and the motor that has led to the rapid failure of the motor. And there was a problem of making juice.

  The design of all centrifugal juicers are approximately the same. From the mouth of such a device fruits fall to the grate, where they are crushed, and then enter the separator, in which the juice is separated from the pulp.
  The power of centrifugal juicers range from 200 to 1300 Watts. Juicer large capacity will allow you to get more juice compared to the low-power juicer. Many models of centrifugal juicers have the power controller.
