A juicer is a device which is used to create juice out of fruits and vegetables. A good quality juicer is one that can efficiently separate the juice from the pulp and foam.
There are three methods of making juice which are commonly used. These three operating mechanisms of juicers are the mastication, squeezing and centrifugal juice making methods.
A centrifugal juicer is the most widely used version for its low cost and faster operation speeds. However, if you are interested in getting a higher yield then you should try out masticating juicers as they operate slowly but squeeze any vegetable and fruit into the dryest pulp releasing the most nutrients and minerals in the process. Unfortunately, it is not easy finding such a juicer cheaply as the auger itself costs a lot to manufacture since it must be capable of withstanding a lot of force.
Like most things in life, with juicers you get what you pay for. To find the best value juicer you should read through juicer reviews online and decide which make and model of juicing machine will provide you with the best long term value.
