The Hydraulic Press Juicer Extractor

Several types of juicers are out on the market, including centrifugal, single gear, twin gear and hydraulic press juicer extractors. Each type operates differently and each has its pros and cons. And some types of juicers do a better job with certain types of produce than others. So, it’s important to buy a juicer that matches up well with what you intend to do with it. For those of you who aren’t familiar with these juicers and how they work, here’s a little basic information.  The most famous brand in this category is the Norwalk Juicer.

As the name implies, a hydraulic press juicer uses pressure to extract the juice out of raw produce. It’s a two-step process that is best exemplified by the tried-and-true but pricey Norwalk juicer, a machine that contains cutting/grinding mechanisms and a powerful, motor-driven hydraulic press.

Basically, the first step involves cutting, shredding and grinding the produce to prepare it for juice extraction. During the second step, extreme pressure is exerted on the “mash” that is produced during the first step. It is this pressure that actually extracts the juice from raw fruits and vegetables.

How this juicer works

If you’re interested in knowing more, here are some specifics on how hydraulic press juicers operate.

The first step in the hydraulic juicing process is called “trituration.” During this step, the fibers in the raw produce are broken down by cutting, shredding and grinding the fruits or veggies until their consistency resembles that of applesauce. The resulting mash is captured by linen or cheesecloth bags or cloth-lined trays which filter out the pulp. The trituration process readies the produce for juice extraction by making the maximum amount of nutrients more easily accessible.

Once the trituration step is completed, the mash-filled bags or trays are placed in the hydraulic press portion of the juicer. The extreme pressure (in some cases as much as 6,000 PSI) exerted on the mash by the hydraulic press extracts the juice and nutrients.

Because the fibrous materials in the produce have been broken down by trituration, this type of juicer is able to extract more of the natural vitamins, minerals, enzymes and other wholesome substances in fruits and veggies than other types of juicers. The result is a nutrient-packed juice that’s also smoother in texture and more flavorful than the juices other types of juicers produce.

The two-step process used is more complicated than the procedures used by other juicers. Hydraulic press machines are also more difficult and time-consuming to use and clean than other types of juicers. At around $2,500, this type of juicer, like the Norwalk is also very expensive. But, they introduce very little air as they’re extracting juice, so oxidation and nutrient degradation are minimized. As a result, juice from a hydraulic press juice extractor will stay fresh, delicious and nutritious longer than the juice produced by other types of juicers. And, the high nutritional value, smooth consistency and extraordinary flavor of the juice a hydraulic juicer extracts are unsurpassed.

Hydraulic presses also do an especially nice job with softer fruits. They’re wonderful juicers if you can afford the time and expense that’s involved.
