High speed centrifugal juicers are not true juice extractors, as the resultant juice also contains finely cut / shredded produce 'blended' into it, often giving the illusion of a higher juice extraction rate. Thus many 'high speed centrifugal juicers' are in reality a cross between a 'juice extractor / blender.' Although they cannot extract a 'living juice', they certainly can produce a "fast food" juice. High speed centrifugal juicers tend to suit busy people or 'beginners' who are happy with a basic quality blended juice.

Cold Press Masticating Juicers ~ Up to 200 rpm:

We chew our food at about 30 to 60 chews per minute via a cold press masticating process, thus insuring maximum nutrient availability. If our mouths were to imitate high speed centrifugal juicers, we would be chewing at an incredible 1,000 to 30,000 bites per minute... That is rather unnatural.

Some discerning customers insist on using only 'Cold Press Juicers' with speeds ranging from 70 to 200 rpm. Cold press juicers are purpose built machines that extract a high quality 'living juice' for maximum well-being.

Cold press juicers are genuine juice extractors that literally extract juice from your produce via a slow speed pressing action, e.g. 'cold press' masticating process.

Because the nutrients are preserved, the juice tastes stronger (much better) and has a much longer shelf-life (especially when refrigerated). These cold press juicers are especially appealing to health enthusiasts, sports people, convalescing patients and the elderly, as recommended by Dr Sandra Cabot.

Many people have been stranded in remote locations and died of starvation, despite being surrounded by various edible foods such as many seaweeds etc.

One frequently overlooked wild food that grows in abundance in so many places - is good old grass!

A major reason given for not using grass as a survival food, is because humans do not have a rumen to digest the grass properly.  But there is another method of extracting the many beneficial nutrients from grass, and that is via a cold press juice extractor. In fact one of the greatest survival tools you could ever own, is a cold press manual juicer, which is perfect for those uncertain times when there is no electricity available.

During times of strikes, pestilence, famine and even war, in most places there is an abundance of grass beneath our feet.  This information may just save your life one day, because although all food supplies may disappear, grass juice can keep you going for quite some time, at least until help arrives, or you are rescued etc.

One upside of living on grass juice for extended periods of time is that you will definitely look like an overachiever of the Jenny Craig program (weight loss program)!  You will also remain hydrated, which is essential to survival.

Observations:

1. The ambient room temperature was just 7 degrees Celsius, thus oxidation took much longer than usual;
2. The first difference that we noticed was that the high speed Champion Juicer required about twice as many Granny Smith apples than the LexSun Standard Juicer, to make just one glass of juice, i.e. the LexSun Juicer extracts 100% more juice than the Champion Juicer;
3. Secondly, the high speed juicer shredded the apples at a high speed, which caused a lot of finely shredded pulp to be mixed in with the juice, slightly similar to a blender;
4. The Champion Juicer cutter operates at approximately 1,725 rpm, which is slower than most high speed juicers (usually range from 1,000 to 30,000 rpm);
5. The LexSun Juicer auger (single gear) operates at just 80 rpm, which is an incredibly low speed;
6. The oxidation process started very quickly with the juice from the High Speed Juicer and soon spread throughout the top 1/3rd of the juice. Within 60 minutes the oxidation was spreading much further;
7. The juice from the Cold Press Juice Extractor eventually developed a very thin layer of oxidation on the top where the juice was exposed to the atmosphere; otherwise there was no oxidation throughout the rest of the juice;
8. After 60 minutes the juice from the high speed juicer tasted much weaker than at the beginning and did not look very appetising;
9. After 60 minutes the juice from the cold press juicer tasted the same as the beginning and still looked great!

Summary:

Cold press juice extractors are a specialty item and usually take longer at juicing compared to high speed juicers; however, the emphasis of cold press juicers is on 'quality', not speed. While the juice from a cold press juicer can be consumed immediately with all nutrients intact, it can also be stored in a refrigerator for days and still remain fresh and packed full of nutrients.

On the other hand, when juicing with a high speed juicer such as a Champion Juicer, it is imperative that you drink the juice immediately after juicing, while the juice is still 'alive.'

Despite the oxidation caused by high speed juicers (which is even worse with higher rpm machines), please keep in mind that it is definitely better to drink a mediocre juice, than none at all!

Single gear juicers have an auger (i.e. single gear) in the juicing chamber, which extracts a high quality 'living juice' in three stages:

1. The auger takes a 'bite' of the fruit or vegetable with each revolution;
2. it then crushes (cold press) the produce at a very low speed, thereby preserving the maximum amount of nutrients;
3. and extracts an ultra high quality 'living juice.'

In summary, single gear juicers (i.e. the LexSun Elite Juicer):

1. Are economical and parts are inexpensive to replace;
2. are excellent for both beginners and experienced 'cold press juicing' advocates;
3. extract the almost the same quality juice as their 'twin gear' counterparts;
4. have a slightly lower extraction rate than 'twin gear' juicers;
5. will not last as long as the higher precision 'twin gear' juicers (i.e. the Angel Juicer).

Twin gear juicers have two gears (i.e. twin gear) in the juicing chamber, which extracts a high quality 'living juice' in three stages:

1. The twin gears continually 'cut' the fruit or vegetables as the gears revolve;
2. then crushes (cold press) the produce at a very low speed, thereby preserving the maximum amount of nutrients;
3. and extracts an ultra high quality 'living juice.'

In summary, twin gear juicers (i.e. the Angel Juicer):

1. Are higher precision machines utilising high quality stainless steel gears, hence are more expensive 'top shelf' units;
2. are excellent for experienced 'cold press juicer' professionals;
3. extract a higher quality juice as their 'single gear' counterparts;
4. have a higher extraction rate than 'single gear' juicers;
5. will last longer than the economy 'single gear' juicers.

It is recommended that you drink at least 250 ml's of fresh living juice each day:

Although eating fruits and vegetables in their natural state does provide a substantial amount of vitamins and minerals, much of their goodness is locked in the fibre which is expelled from your body. However, you can obtain additional benefits from them when they are juiced, especially with a quality: low r.p.m. - cold press type - non-centrifugal juicer.

When you juice fruits, vegetables and etc., their goodness is released from the fibre and you are able to drink their highly concentrated nutrients, which are then able to enter your bloodstream very quickly and efficiently.

For Maximum Benefit:

It is recommended that you swirl the juice around in your mouth a little, thereby mixing your living juice with your salvia, which aids in a more complete digestion. This is especially applicable to carrots, as in their normal state carrots require considerable chewing. Drinking fresh juice before a meal often reduces hunger at meal time.
