That might seem obvious, but in reality, you can make juice without a juicer. Most juicers come with their own jugs, but if yours doesn't have one, you'll need 2 jugs or containers. The grinder is the key part of the machinery that facilitates this process. Grinders can prepare fruits, vegetables and other ingredients for extraction.
Grinders come in many sizes and capacities. The grinder a company chooses will depend on the desired processing speed, the size of the incoming product and the desired particle size of the ground product. In the juice industry, screw-fed disintegrators are a very popular type of grinder, since they integrate controlled feeding with grinding. This direct diet has eliminated many problems related to products that are difficult to feed, such as leafy greens, melons and tubers, in addition to reducing the labor required by manual feeding.
A commercial centrifugal juicer is the most common type of juicer for bars and juice vans. It squeezes just about anything, is fast, easy to clean and is generally cheaper than other types of juicers.
