a Juicer In the 1930 s a chap called Dr Norman Walker invented a juicer which firstly grated and then cut produce The resulting mass was then to be put into a linen bag and placed under a hydraulic press directing juice down a spout Dr Walker lived to 108 years of age he died in a surfing accident You can still purchase this 2 stage Norwalk machine for around 2000 which is a very prohibitive price indeed And most of the juicers you will find on sale haven t evolved much since then which brings us to Centrifugal juicers Centrifugal juicers work by using a flat cutting blade on the bottom of a rapidly spinning strainer Cut produce is flung out over the sides of the strainer Due to the centrifugal force juice then passes through tiny holes in the strainer Features intrinsic to this design include The strainers are HUGE and a pain to clean The cutting blades are tricky to clean and some are particularly dangerous to handle The process incorporates mass oxidization and therefore a dying and brown juice There is a lot of unpleasant froth Leafy green vegetables are impossible so no herbs and no wheatgrass Pulp builds up in the strainer and efficiency falls rapidly The centrifugal force pushes a lot of pulp through the strainer resulting in a lot of pulp in the juice These juicers can seriously damage your hearing and won t be popular in a terraced house or flat or if anyone is still in bed 3 Ultimately the technology inside a centrifugal juicer is not unlike that of a tree cutter They re spinning at up to10000rpm The resulting frictional heat is not good for your juice Neither is 10000rpm an easy task for a motor when under constant resistance The amount you can spend on a centrifugal juicer varies from 30 to over 100 so what are you paying for Well in truth mostly brand name and aesthetic design While the cheapest of machines are certainly week hearted and not going to last you long experience and feedback tells us that more expensive machines don t necessarily last any longer In fact if everyone who bought a juicer used their machine every day we think nearly every machine on the market would be withdrawn because with daily usage virtually all machines would fail within their first year let alone within warranty This guide has been written as a result of the cumulative experience of several people spanning over 4 years and many many juices In this guide you will discover clearly the best type of juicer for you pinpoint the best machine in each category be saved from the confusion of conflicting promotional material benefit from unique comparison charts and photos gain links to background information and in dependant reviews And that s a brave statement for us to make but far braver is the warranty provided with juicers Most people we speak to that have burnt out previous machines never even took it back We live in a throw away society sadly but it s great for manufacturers Another fact of society is how many of us shelve new products In a recent survey juicers were found to be the most likely new item to be left in 4 the cupboard second only to the George Foreman style grills We believe this is because of the above drawbacks of this style of juicer as the high street centrifugal is by far the most purchased type of juicer in the UK Centrifugal juicers that handle whole produce WOW what a feature whole apples whole heads of celery Having said that impatience isn t the highest virtue One health food author tells us it s great being able to put in a whole head of celery but the motor keeps burning out and I have to take it back to the shop Ultimately this feature is one of convenience but the process still destroys the juice and you still have to clean up after every glass produced as the strainer clog seven more rapidly The juicers themselves have had no technical redesign other than a widening of their feeding chute so there has been no consideration of increased motor resistance Also a wide feeding chute is extremely dangerous an adult could loose their whole arm in there Also anything that doesn t fill the chute rattles all over the place like a simple carrot Generally there is immense volumes of foam and the juicers dump a lot of pulp into the juice which then requires straining How many juicers do you want to buy this year One last word on whole fruit juicing animals that live inside fruit Think about it even if your juicer can take whole apples maybe it s worth quartering each apple first worm juice anyone Centrifugal juicers with pulp ejection A relatively small market place that holds a few domestic machines and mostly commercial machines used by juice bars Juice bars need juice QUICK which is why they have to sacrifice quality 5 and use the centrifugal process and they can t afford to continually disassemble their juicer to clean it In a centrifugal juicer that has pulp ejection the sides of the straining basket are cleverly slanted the air flow sending the pulp produced automatically into a collection basket without the need for cleaning The process IS NOT full proof by a long way and offers no inherent improvement on all the flaws of centrifugal juicing already mentioned Please be aware that stringy fibrous produce and wheatgrass is still not a success in this type of juicer If you re looking to incorporate these into your juice read on A revolution occurred in the 1950 s when Plastaket invented the Champion the worlds first masticating juicer Masticate means to chew and as the Champion is the only juicer with teeth we feel it s the only masticating juicer available Many other web sites will class gear juicers as masticators We have put these into their own category below The Champion juicer gives a greater yield then centrifugal juicers and the degradation isn t nearly as severe But its cutter is running at 1425rpm and that can be a problem Leafy veg is still a NO only now it gets caught in the teeth If you juice slowly or the teeth are clogged with plant fibers you get warm foamy juice as the cutter is spinning rapidly against the produce that hasn t yet cleared the juicing chamber When the Champion arrived on the scene over 50 years ago Siegfried Gursche author of Healing with Herbal Juices described as a tragedy the extremely high speed of the juicer which causes lots of friction which heats and sometimes even steams the juice Some nutrients especially all live 6 enzymes are destroyed by heat Where the Champion excels in terms of speed of throughput and yield is with root vegetables If you re planning to process A LOT of carrots then the Champion would be a consideration for you i e the Gerson Diet Although in our opinion you d still be better off with a gear juicer and you should make green juices your main stay To read more about why the Champion should be nominated for retirement click here Now lets take a jump into the 1990 s Suddenly an innovation occurred in juicing Low speed gear juicersGear juicers operate anywhere between 70 and 120 r min Thus in a gear juicer Produce is crushed No cutting or spinning Enzymes are preserved AMAZING green juices become possible Your juice is cold as it should be You lift a glass of living juice every time They are the easiest of all juicers to clean don t let anyone lie to you and claim that any juicer mentioned previously in this guide is easy to clean they re not As a visual representation of the differences we have prepared two glasses of apples juice one prepared in a single gear juicer the other in a centrifugal juicer The rapid oxidization of apple juice makes this a good test for the colour and therefore vitality of the juice Other produce would show similar results for the centrifugal produced juice but typically the single gear prepared juice would exhibit less or no foam E g orange juice is entirely foam in a centrifugal juicer and zero foam in a single gear juicer Many people have said or written that you need to drink juice produced in a centrifugal juicer straight after producing it Usually it is explained that as the juice deteriorates 7 you can benefit from the juice by consuming it straight away PLEASE stop and think If a process causes destruction removing it from your sights quickly does not alter the destruction If you want to juice for health you must produce the juice yourself in a low speed gear juicer This is the only way to gain benefit from the abundance of nutrition available in fresh fruits any vegetables when their fibre is safely separated No other Apple juice extracted with a Single Gear Juicer Has a healthy even color showing that it s full of enzymes and nutrients 20 more juice yield Less foam Apple juice extracted with a Centrifugal Juicer has oxidized and turned clear brown only water content with no enzymes andnutrients poor juice yield A lot of foam domestic or commercial juice preparation will give you the benefits of living enzymes vitamins minerals and other phytonutrients So now that we re totally convinced that it s only worth drinking fresh juice if prepared using a gear juicers weare left with one question single gear or twin gear Single gear juicers A single gear juicer has a single rotating screw or auger with an ever narrowing thread along which produce follows until crushed inside a screen which allows juice through and pulp to be ejected at the tip This process is very similar to the worm gear of a meat grinder The auger is divided into a two phase process of first crushing and then wringing out the produce against the wall of a conical filter screen Single gear juicing offers you top quality juice with ultimate friendliness of use You won t ever be put off using a single gear juicer 8 it will forever remain a joy In the UK the original Oscar 502 has just been made available again as the Oscar Living Juicer a machine you ll see in juice bars like Planet Organic There are a hoard of other single gear juicers available now including the L E quip Visor Solo Star and Live Please take note that despite superiority claims of the enzyme content produced by different gears juicers there is NO evidence or test ever been done to identify if one machine is more successful than another in this area It seems that all promotional material for this type of juicer including unedited web copy claims superiority We would advise not basing your purchase around such statements Additionally there is no evidence that slower is better relative to this category i e 70rpm is not better than 120rpm TRUE slow speed has immense benefits over thousands of revs per minute but the small differences in speed between juicers in this category are not cause for you to choose the slowest Single gear juicing was invented at the beginning of the nineties with the introduction of the Oscar 502 designed and Manufactured by a Korean company named Dong Ah which was founded by two business partners in 1988 One of the two businessmen betrayed the other set up a nearby manufacturing facility started a new company called Dong A Oscar cheeky hey and within a short time had produced the Matstone juicer a copy of the Oscar design Outside of Korea the machine was branded the Samson and globally Samson agents touted their machine as the new model Oscar They cut a number of corners to make their Matstone juicers more affordable and 9 pushed heavily with their marketing In one country an ex employee of the Oscar distributor stole 75 000 and the customer database before setting himself up as the Samson distributor In the UK where there was no resident Oscar distributorship the Oscar was long forgotten many people believing to today that their Samson Matstone machine is the new Oscar The story nearly finished with Dong A Oscar falling to bankruptcy on 26th September 2005 Enzyme juicers These have not proved as efficient or reliable as the Oscar brand We recommend looking closely at warranty durations as the Oscar Living Juicer offers 12 years and only one other machine beats that Dual stage single auger juicers The latest innovation in single gear juicers is a 3 phase extraction auger working inside a dual stage juicing screen Upon the initial crushing of the produce any released juice is directed through the first stage of the juicing screen into the juice collecting bowl The crushed produce minus much of its juice then continues its way through the machine where there is a finer holed screen to obtain not only a higher yield but a near pulp free juice The picture below compares a dual stage juicing screen top with a single stage juicing screen bottom Clicking on the picture will show alarger picture This process is claimed to obtain up to 20 more juice than ordinary single gear juicers and mostly yields like a twin gear machine A test with carrots yielded 26 more juice With other single auger juicers the juice is only produced in the second stage requiring larger holes in the juicing screen Consequently a sieve is provided with other single gear juicers covering the juice collecting bowl to catch pulp As juice 10 is allowed to exit at the first stage this type of juicer doesn t suffer from a number of problems that affect virtually all other juicers Leaks especially into the locking clip and motor housing this causes long term problems with the gearbox as fruit acids reach the lubricating grease within the gearbox causing extra noise and eventually a breakage additionally locking clips face plates of juicers are tricky to clean and add to your time Poor performance with soft fruits soft fruits hold more juice extractable at the first stage When trying to pass this juice onto the second stage of ordinary single gear juicers typically nothing happens at all and produce remains stationary in the juicing drum with the juice and all the auger does is stir it There are only two dual stage single gear juicers available on the market the Solo Star II and the Oscar 900 VitalMax You ll note that both brands have been worn on earlier models We prefer the Oscar VitalMax for a number reasons including a lighter sleeker design as well as being easier to use and clean Also both stages of the Oscar juicing screen are stainless steel where as the Solo Star II has a plastic first stage Lastly the Oscar VitalMax is the only juicer to hold a 20 year motor warranty Now that is a brave warranty to implement Oscar assure us that their machine has been tested beyond 10 000 hours of use They insist we juice daily and insist that they use the finest motor and components in the world Perhaps some tell tale signs of this quality reside in this machines performance and quietness as the VitalMax is most definitely the quietest machine we ve used Since Oscar have been in business since 1988 it is safe to 11 trust their warranty offering too Single gear juicer with NO juicing screen The Oscar VitalMax is absolutely the most reliable best performing quickest to clean easiest to assemble and use appliance of it s type AND it has the least number of parts just 4 plus the hopper There is one single product in this category the Live Enzyme juicer which is an electric version of the inexpensive manual juicer known as the Easy Health Both the manual and electric version were designed for use with greens particularly wheatgrass exclusively Due to the very high stringy fibre content of these foods they don t create pulpy juices and thus a juicing screen is not necessary However the absence of a juicing screen on these machines is coupled with claims of juicing all produce and headlining of the time you ll save not cleaning the screen Proceed with caution You will need to sieve and softer produce is problematic Ok if you like pulpy juice but when you want just pure juice without the pulp the pulp quickly collects on the sieve clogging it up If the sieve was integrated into the juicing drum then separated pulp would be deposited away from he juice but with a sieve resting on the juice jug you have to empty it frequently and waste a lot of juice in doing so This is very messy especially with soft produce including apples and tomatoes will lead you to give up hope Finally two augers are provided with this juicer for different produce another unique feature But presuming you require both at some point you may wish to change the parts to juice the next item in your recipe Messyagain Below is a chart of the power watts of the 5 most popular single 12 gear juicers This is an important comparison because each one of these juicers has a 38mm feeding chute and thus has the same task to endure Ultimately the higher the power the lower the motor wear of a single juicing task The power of a machine is exhibited in the juicing performance too but if you compare this with the warranty chart above you can see exactly what you are getting People have always thought of the higher price tag equipment as too expensive but what they don t realize how many cars do you want to buy in the next 10 years How many vacuum cleaners do you want to own How many times do you want to buy a stereo Or do you want to buy something and be partially dissatisfied with it because every time you use it it breaks on you Or do you want to do it once and do it right After all you know you get what you paid for in the sense not that you pay less money because in the long run you can pay more money One of the things I ve always thought is that I hate buying junk Because I end up buying it again How many of you have bought many of the same product because you never bought a good one The thing about the Oscar is it still exists not just as a legend but people out there still own their Oscar 502 and it s seen them through a decade Even Dr Gillian McKeith is pictured using an Oscar in her books she s owned that juicer forever The Oscar is the juicer of choice of The Juice Master Rose Elliot and many many more people who only want to buy once and get it right so they maintain their image when recommending theproduct to others Twin gear juicers So why twin gear Well twin inward rotating gears have 13 traditionally allowed for a greater juice yield However assembly is a little more fiddle some with more parts the price escalates considerably and feeding in produce is a slower affair than with single gear juicers If you ve used a centrifugal juicer then a single gear may feel a little slow but a twin gear will surprise you as many types of produce have to be forced in between the gears Basically a twin gear juicer performs its results by operating its gears at 0 1mm apart around 4 1000 of an inch Whilst wheatgrass herbs and other leafy produce will self feed as the gears pull inward a carrot would require force This is an important note for anyone who has any weakness in their forearms and especially wrists if you re unable to use a hand trowel in the garden then sadly a twin gear juicer may be too much for you This design of twin gear juicers often makes soft produce a challenge Fruit remains feasible in a twin gear juicer but juiced alone would require some extra patience Twin gear juicers always provide a larger holedscreen for fruits When ever a web site tells you that the gears of their juicer operate closer than anyone else s please be aware that they all operate at this distance they all give the same figures and make the same uniqueness claim Twin Gear juicing was invented by the designer of the current Green Star Juicer Mr Jong G Kim of Green Power which was originally named the Green Life Massive competition in Korea saw most juicer manufacturers go out of business including Mr Kim As Green Power had recently entered the international market its parts suppliers joined forces to recover the debts of their customer Simply 14 they sold off he moulds to Tribest an American distributor who have continued to market the machine despite there being no development or after service at source in Korea M
