The advantage of juicing raw vegetables lies in separating the juice from the fiber, thus retaining the bulk of nutrients in the juice. Because the fiber has been removed, these fresh, living nutrients in the juice can enter into the bloodstream and that at cellular level, within minutes, without the time consuming and energy-depleting process of digestion.

Our modern toxic lifestyle demands that we nutritionally supplement with juicing. Some people even call it a medicine. You can literally “make your juicer your drug store.”

Juicing is the most natural, fast and cost effective way to get nutrients at cellular level, in order to:

  • Regain and boost your health and vitality
  • De-tox cells
  • Boost your immune system with mega loads of antioxidants
  • Purify the blood
  • Accelerate healing with ample building blocks to replace damaged cells
  • Spike the energy levels
  • Nourish the body with nutrients in synergy
  • Hydrate the body

There are plenty of different juicer types and brands, using different processes, on the market today. As with most products out there, there are horses for courses. We will explain them all in order for you to make an educated and informed choice, when purchasing a juicer. There are basically 5 different juicer types which we will elaborate on.

THE 5 JUICER types:

There are basically five different juicer technologies.

  1. Single Auger juicers
  2. Twin Gear juicers
  3. Twin Gear technology combined with 2 low pressure Augers – The ANGEL juicer.
  4. Centrifugal juicers, we do not stock them, reasons will be explained.
  5. Hydraulic juicers, we do not stock them, reasons will be explained.

The KEY PRINCIPLE of JUICING

There are always two key stages in any juicing machine

  • Firstly to make a pulp (the juice and fiber mixture),
  • Secondly the pulp must be dried out. At this stage the juice is separated from the fiber. It is crucial to note that the quantity and quality of the juice, is completely dependent on stage one. A juicer cannot extract juice out of chunks of the juicing substrate that is still solid.

1. Single auger technology juicers:

This technology is an entry level juicer. All the working parts is mostly a polymer (plastic).

The single auger of this juicer has two functions:

  1. To pulverize the juicing product and,
  2. To squeeze/apply pressure and then to extract the juice at the end of the auger at high pressure.

The pulp made by a single auger juicer is noticeable chunky with solid pieces in the pulp. Chunks are a sign of inefficiency plus unused juicing substrate, thus less juicing yield.

Single auger juicers are also called ‘masticating’ juicers. The auger technology works as follows; the juicing product is forced with the rotating juicing auger from a big volume to a small volume. Grating the juicing substrate between the auger and juicing screen. This auger juicing process is not a constant volume process, meaning that the auger rotates in a tapered shape reinforced juicing screen, shaped as a tapered cone – from big to small. The pressure builds up as the juicing substrate moves down the taper and only a percentage of the juicing product bursts and releases its juice.

Since single auger juicers are mainly made of plastic materials, the clearances between the working parts; the auger and the juicing screenare bigger. Thus the single auger process loses pressure more regularly. This is another fundamental reason why single augers juicers is less efficient in juice yield. Plus under working pressure these plastic components expand more than metal, resulting in even bigger clearances. The juicing yield is below average. Juicing yield is as good (or poor if you will) as with the centrifugal juicers, but unlike the latter, it is not aerated and can be stored.

The advantages of single auger juicers:

  1. Quiet operation.
  2. It can juice wheat grass and leafy vegetables.
  3. It is more versatile than the centrifugal and hydraulic juicers.
  4. One can store the juice for up to 24 hours.

The disadvantages of single auger juicers, in summary:

  1. They are frustratingly slow.
  2. They need much more juicing preparation, since it has a small in-feed and the juicing substances need to be chopped to size to fit through the in-feed.
  3. Disappointing juice yield, as with the centrifugal juicers.
  4. Not as durable, as all the parts are made of plastics.

2. TWIN GEAR juicers.

The twin gear juicing technology is a far more advanced juicing process. The twin gears are finely engineered with very tight clearances which allow for up to 25% better juice yield than the single auger juicers.

The twin gear juicers have either a 2 or 3 stage juicing action:

1. Stainless Steel (SS) gear section phase:

During this phase the juicing substrate is made in a very fine pulp ready for the juice to be squeezed out.

2. Screw press phase:

To increase the pressure at constant volume and to squeeze and extract the juice from the fine and pulverized pulp.

3. Knuckle press phase:

For improved pressure and juice yield, only available in the new model GS Exclusive 5000.

Because of the precision machined twin gear construction, the gears are extremely effective in pulverizing the juicing substrate. The juice is extracted at constant volume (no taper from big to small). It has a unique pressure relieve valve, fitted onto the front of the juicing chamber. All the twin gears of the twin gear technology group are parallel; this gives a constant volume process with minimal internal friction and heat build-up. The only friction occurs when the already dry pulp exits the juicing chamber.

The advantages of TWIN GEAR juicers:

  1. Quiet operation.
  2. Fast.
  3. Less juicing preparation. As the in-feed chute is bigger, it will take a big carrot without chopping.
  4. Much better juice yield than the single auger and centrifugal juicers.
  5. It is more versatile than the centrifugal, hydraulic and single auger juicer.
  6. Juice can be stored for up to 48 hours.

The disadvantages of TWIN GEAR juicers:

  1. Although it is durable juicers, and the twin gears are made of surgical stainless steel, most of the parts are made of plastics.

3. ANGEL technology

Having twin gear technology combined with 2 independent low pressure augers, the Angel juicer is superior, in that the Angel juicers is at present the only juicer on our planet that combines both these juicing technologies. It is truly unique and the most advanced and effective juicer on the market. It is very well designed and built, and in my opinion has no rival among juicers.

The Angel juicer is in a class of its own, in terms of:

a) Supreme juicing yield efficiency, between ±70-90% by mass.

b) Combining the twin gear technology with 2 low pressure augers

c) Being precision made, with surgical Stainless Steel that provides much smaller clearances. Smaller clearances always result in higher pressure and much better juice yield.

It literally produces almost double the amount of juice as with single auger and centrifugal juicing technology. But it does not stop here. The Angel and Green Star juicers use the twin gear technology that makes a fine pulp of the whole juicing substrate. Thus you extract juice from a broad and complete spectrum of all the nutrients in the juicing substrate. However with a single auger and centrifugal juicer,one extracts juice mainly from the softer watery core parts. A chemical analysis of a similar size juice sample (same batch of carrots) from all four of the 4 different juicers was made and the nutritional value of the Angel juicer three times exceeds that of the centrifugal or single auger juicers.

The advantages of Angel juicers:

  1. Much more juice, with far more nutrients

The nutrients next to the outer skin of the juicing substrates are superior in nutrients, and the Angel is perfectly equipped to extract juice, even the toughest of tough juicing substrate.

  1. Superior rich taste and colour of the juice.
  2. Quiet operation.
  3. It can make seed juices from soaked seeds.
  4. Less juicing preparation, since it will also eat a big carrot without chopping.
  5. Much better juice yield than the twin gear, single auger and centrifugal juicers.
  6. It is more versatile than the single auger, hydraulic and centrifugal juicer.
  7. One can store the juice for up to 48 hours.

There are no disadvantages!

4. Centrifugal juicers:

These juicers work on grating the juicing substrate to a very fine consistency and then parallel to that, it spins the juice that is exposed on the outside of all the grated particles with high centrifugal speed and force. This process introduces oxygen bubbles that cause a foam broth that is always evident on the surface of the juice. Juice made with a centrifugal juicer does not last and because of the introduction of plenty small and microscopic oxygen bubbles, the freshly made juice oxidizes very quickly. Normally the juice turns brown within ± 10 minutes. Even if the juice made from a centrifugal is consumed immediately, some of the nutrients would have already been oxidized, due to oxidization during processing.

The advantages of centrifugal juicers:

  1. It is normally a bit faster than the other technology juicers.
  2. It is inexpensive.
  3. Some have big feeding shoots, but unfortunately, only suitable for fruits and root vegetables.

The disadvantages of centrifugal juicers:

  1. Oxidization – The juice discolors and loses taste very quickly. Centrifugal juicers make use of an ultra-high speed (± 6000 RPM) centrifugal process. The single auger, twin gear juicers and the Angel juicers only operate at a fraction of that speed, between 84-110 RPM. Some brands from a marketing point of view claim that their centrifugal juicer runs at slow speed (2 500 RPM), but is still very high, plus the process still has its limitations as discussed earlier.
  2. This juice cannot be stored.
  3. It cannot make ultra-healthy leafy green juices, e.g. wheatgrass juice, broccoli and other leafy vegetables juices.These type of juicers are predominantly used to juice fruit, but fruits today are most probably hybridized, and contain too much sugar. They also lack nutrients due to the artificial fertilizers, unlike the fruit our predecessors would have enjoyed. The issue is nutrition.
  4. It can only juice small quantities at a time, because the pulp bucket needs relatively regular emptying, however some of the newer models expel the pulp.
  5. The juicing yield is very poor.
  6. These juicers are a mission to clean.
  7. They don’t last, i.e. durability is not as good.
  8. They are noisy.
  9. They are not versatile as some of the other models, which can also produce nut butters, sprouted grain dough, frozen fruit sorbet’s, raw soups, etc.

5. Hydraulic juicers

This process works with a hydraulic press system. It first grates the juicing substrate and then squeezes the pulp with a hydraulic press.

The advantages of hydraulic juicers:

  1. Very good juice yield. However, it is approximately 10% less than that of the Angel, but superior to all other technologies.
  2. It runs quietly.
  3. Minimum friction and oxidization.

The disadvantages of hydraulic juicers:

  1. They are horrendously expensive, ± 7 times the price of a Green Star or ± 3 times that of an Angel juicer.
  2. As with central fugal juicers, they are not as versatile, they have limited food processing capabilities.
  3. Extra time and effort is required.

The juicer work as such, that after the substance is mechanically grated, the grated pulp needs to be placed in the juicing bag, the filled bag on the juicing platform and after the juice has been pressed, each bag needs to cleaned out,washed and stored in the fridge.

SUMMARY:

At the end of the day, there are different strokes for different folks.Remember any juicer is better than no juicer. Juicing is a discipline, it will cost you time, but you will gain immeasurable health and vitality by juicing regularly.
