My New 'Koh-I-Noor' 2800RPM Spin Dryer

[mattywashboy]

Hi Guys

Just taken delivery of a new purchase (its never ending these days) for the laundry room.

Its a Koh-I-Noor Eco Spin Dryer, 2800RPM. Holds 5.2kg of clothes.

I was searching around the internet for any spin dryers available in Australia, there appeared to be none to be found. Then I found a link via Twitter for the Oziel Eco Appliance website and they have just begun to import Koh I Noor spinners into Australia, with Sydney as their base. Its an Argentinian based company I believe.

Anyway I shot the guys an email asking about prices and shipping to WA. They were so good and informative and sent a lot of info on the appliance. I considered it for about a fortnight (during which I got the Frigidaire washer) and then sent off the money and they packed it, shipped it and it was on its way.

I have never really used a spin dryer before, my family in England had a few amongst them but I never saw them using it, the closest I got was the spin dryer on my grandmothers Servis SuperTwin and my other grandmothers Hoovermatic, both of which I was terrified of because of the noise. In later life my Hoovermatic Grandmother had a spinner in the corner of the kitchen but she never used it while I was around, she was from the era where you got up at 5am and did all your laundry before 9am before heading down into the town to shop...

I bought one because of the busy lifestyle I lead and the struggle to get laundry dry in the cold Perth winter without running the dryer for hours and hours on end. I set aside one or two days and if I don't get my laundry done on those days then it gets leftover to the next week...

The Spinner really does get much more water out after the 900rpm spin in the Frigidaire, teas towels and socks come out almost dry and towels come out needing only an hour or so on the line. I am yet to try it on T-shirts and such but all will remain to be seen, so far, very impressed.

If any other Australians are interested in this appliance I will put a link at the end of this post to their website, it is still under construction but the email address is there for sales. I paid $466 for the machine, 1 year warranty and shipping to Perth.

For now here are the obligatory pictures and a short video...

Enjoy

More photos.

Very nice inner drum.

 

[mattywashboy]

The branding,

Interesting that we have an Indian restaurant just up the road called the same as this 'Koh I Noor', not bad food either, usual after effects of spicy food apply though...ahem.

 

[mattywashboy]

Finally the very simple video I quickly made.

Apologies for the dust and dog hair around the floor, once the laundry was all done i went into the mad sweeping vaccuuming mopping phase of my one of two days off from work. Leave it up to the housemates and we would be able to build a replica of the Titanic out of dog hair....

Anyway thats all for now, thanks for viewing

Till next time.

Interesting.

The only Koh I Noor brand I'm familiar with is the one that makes (made?) Rapidograph technical pens.

Now put this on the VFD motor drive controller!

Soil In Laundry After Final Spin

Matt
Thank you for the video. Could you please just clarify a couple of points?
1. The laundry placed in the video had come from the Frigidaire after its ‘fastest spin’ (900rev/min), is this correct?
2. What is the diameter of the tub in the spin dryer? For the following I have assumed it to be 12 inches.
The Frigidaire trundling away at 900rev/min has a linear speed at the periphery of the 22 inch diameter drum of approximately 5,184 ft/min (52.9miles/hr)
The spin dryer at 2,800 rev/min and assuming a 12 inch diameter drum has a linear speed at the drum periphery of approximately 8, 796 ft/min (89.8 miles/hr), no wonder it takes out more water!

Did you notice how ‘dirty’ the water coming from the spin dyer was? The amount of soil left in that water is the same, in proportion, as the ‘water’ left in the laundry. The more ‘water’ you leave in the laundry and then dry, by whatever means, the more soil you leave also.
Additionally as front loaders use so little water for rinsing the proportion of soil left after each ‘rinse’ is larger than for a similar capacity top loader using more water. The problem is, in my view further compounded by front loaders not utilising the maximum spin speed for the selected cycle after each rinse, this would thus remove not only more water, but more soil as well.

"YOU GET MORE FROM KOH I NOOR!"

RE "Koh I Noor brand I'm familiar with is the one that makes (made?) Rapidograph technical pens"

As once a Koh I Noor dealer; their slogan for technical pens was "YOU GET MORE FROM KOH I NOOR!"

Hey Limey

Yes the laundry in the spinner was out of the Frigidaire after a Regular spin at 900rpm, never timed how long the spin is.
This was just a small load in the spin dryer of small socks and tea towels, i still couldn't believe how much more water it was able to drag out. When I spun the other half of the load which were big bulky bath towels, the water was virtually flowing out of the spinner, brilliant because they only needed a small amount of time on the line before they were dry.

Not sure what the diameter of the tub is, around 12 inches sounds about right but i can't find it on the machine.

I am very happy with it so far, washing my clothes tomorrow so will see how it does on (a) my jeans and (b) my light t-shirts, wondering if it will crease them too much but i imagine they would just be about ready for ironing once coming out of the spin.

The Frigidaire is not the best at rinsing. It uses a low level and does two short spins in between the rinses if you use Extra Rinse (i always do). With E.R not selected you get a slightly longer 600rpmish spin. THe spinner certainly dragged out more soap and dirt.

Drum Diameter of Spin Dryer

Matt,
For the diameter of the drum just measure the diameter of the 'safety disc' you refered to in the video.

Time for New Glasses

I wasn't able see soil in the extracted water and an opaque container on a yellow floor could certainly "color" the outcome.

 

[arbilab]

Which Frigi are we looking at, and how much difference is there between two of them? Mine is from 1998, the first one offered in US, 800r spin, but it has FIVE rinses. Sudsaway spray and 4 fills. If I've dosed detergent right, final rinse water looks like I could drink it.

Besides the nostalgia of growing up with FL, I paid more than double the TL price for this thing specifically because FL rinses better with less water. In a large volume single rinse, what's left after wash spin can only get "so" diluted, and the same remnants in the rinse water remains in the load. In multiple small volume rinses, the remnants get progressively diluted and extracted. Not possible to convince me that a single 16 gallon rinse works better than four 4 gallon rinses.

 

[whirlcool]

That looks like a nice machine of high quality. It sounds very quiet and almost no vibration. You'll love how much water it takes out of shirts and denims!

Water And Soil Extraction

arilab,
Thank you for your comments. I would largely agree with you. However please note that the original poster, Matt, did note soil in the water extracted by the spin dryer.

Electrolux, who totally own Frigidaire, have informed me, in writing, that the water consumption per each wash or rinse phase of the cycle is 5-6 US gallons, depending on load size, for that model of machine, I also have one.

The main point I was trying to make was/is that ‘modern’ TL or FL machines do not spin fast enough to get as much of the residual water and thus soil, out of the laundry, as does the 'old fashioned' spin dryer.

 

[streakers]

Love it!

and want one!

Matty could you please provide me with the details of their website? I've just done a quick search - but can't find a website for them??

Many thanks and Congrats on your purchase!

Cheers
Steve

Hi Steve,

I have sent you an email to the address in your profile page with all the details I had on the websites and email address needed to contact the seller.

Regards

Hard to imagine being stingier per fill than my Frigi but anything's possible specially in 13 years.

Enchanted by "EL" Secarropos Centrifugo. Reminds me of my Pana twintub, you could wear shirts or use towels right out of the spinner. By comparison the Frigi is no big whoop.

Rinsing

To arbilab,
First my apologies for incorrectly spelling your name in my last post.

Secondly I have just noticed that our Frigidaire built ‘Kenmore’, the very, very close relative of the one Matt has, does not ‘spin’ at the end of the wash cycle but just ‘pumps out’, thus leaving more contaminants for the first and subsequent rinses.
I would not have thought that this was the most effective way of obtaining ‘clean’ laundry.

 

[arbilab]

NP, Limey, hadn't noticed. Ar bi lab is just my initials (RB) followed by lab where I mostly worked. I use it as a screenname because it's never taken.

There's definitely a bunch of 'Frigidaires' with substantial differences. REG and PP have a wash spin on mine, delicate does not.

"Safety Disc"

That would be known as the "spin mat".

Spin Mat On My Paki Built Spin Drier

Tore itself into halves within the first week of use.

Not one to be put off by minor details, simply took some flannel yardage one had in the sewing kit and used it instead. Now before anyone wags their finger, extractors have been around longer than those little mats, and until they came upon the scene operators simply took a heavy/thick towel or other material and put it over the load.

What is important is that one pushes the load down into the extractor, and that is isn't over loaded. If this done there is little chance for "rug burns" to materials from being rubbed about at high speed. It is also important to place small items in mesh bags or at least load them first so larger things will cover.

 

[arbilab]

Grandma taught me to pack the spin load so it didn't expand upward. That was 1951. You'd think wisdom would propagate. But if you look where we ended up, maybe not so specially.

 

[tomturbomatic]

Limey, you are absolutely correct about the importance of adequate extraction between water changes in good laundering. According to a textbook in my father's collection, when a wash bath is drained and the load not extracted, as used to be the case for large industrial washers in the last century, fully half of the soil was left in the load which is why several detergent baths were needed and then multiple rinses at high water levels including a sour rinse with an acid added to neutralize the alkalinity of the wash products. When I look at front loaders, I want to know about the spinning between the water changes. Unlike a toploading agitator washer, a front loader does not force water through the fabrics. It saturates them and tumbles them, but it does not force water through them like the fins at the base of an agitator. That is why it is so important to spin as much of the water as possible out of the load before the next rinse. Better front loaders do this. Bendix did this from the start and the lack of a spin between the two deep rinses in a Westinghouse was a shortcoming in my opinion.

I noticed last night when looking at the Laundry Room Forum that Spin X is still selling an extractor. It is $599, but with the extraction capabilities of the Mieles, I don't think it would make much sense to buy it unless it could be proven that it would prolong the life of the machines by slowing down the selected top spin speeds and spinning things in the Spin X.

Tom IS the book A guide to Good Laundry Oprations ?

Also a extract could be take the place of a rinse anywhere in the wash formula.
But this was also back when washers actually had enough water in them to do the job right, not just a gallon or 2 . Wash level in this machine was 9" Rinse was 12" There was a extract after each of 3 rinses and final of 900

Hello Mac! Good to see a post from you. Actually the book is Industrial Detergency, edited by William W. Niven, Jr., published in 1955 by Reinhold Publishing Corporation. It deals with methods, materials & equipment. It has chapters on detergent materials, laundry industry, drycleaning, textile processing, foods & beverages, dairy industry, dishwashing, metals industries & general industrial cleaning. It was Daddy's go to book and my treasured source of information. I liked it as a kid because it has pictures of equipment as well as procedures and information about chemicals. It is where I learned about the "hot break" you use where a pH of 11.2 to 11.6 will allow the first suds to safely be above 100F without danger of setting albuminous stains. Each time I take the book off the shelf, I remember where it was in my father's office.

In a table of the washing procedure for a 300 lb load of family white work, I learned that the 5 suds baths were at 6 inches of water in the cylinder which corresponded to 150 gallons of water. The first, at 100F had an extra 1/2 lb of alkali added along with 10 gallons of built soap solution "for the purpose of neutralizing the acidity in the clothes and, to a certain extent, overcoming the hardness properties of some of the metallic salts that may be contained in the clothes." That is where I learned how important the STPP is in removing the anti-perspirant film from textiles. "Perspiration and acid materials from the body may reduce the pH of the clear water solution to 6-7" so it needs the build up in alkalinity. As the washing progresses through each 6 minute bath, the temperature rises from 130F for the second, to 160F for the 3rd, 4th and 5th with declining amounts of built soap solution from 5 to 4 to 3 to finally 1 gallon in the 5th suds to keep the remaining soil in suspension. The last 6 minute bath is at 150F for the bleach. The built soap solution consisted of 110 lbs of 88% high titre tallow soap and 50 to 60 lbs of alkali dissolved in 1000 gallons of water so it did not have to dissolve to begin working.

The 1st 3 rinses are 2 minutes each at 170F and all 5 are with 12 inches of water or 300 gallons. The 4th is at 140F. The 5th is the bluing rinse at 110F for 5 minutes and the sour to pH 5.0 is at 90F for 5 minutes. So much for the efficacy of cold water rinsing. The coldest I use for washing and rinsing is 78-80F.

The procedure has been changed with some steps eliminated with washer extractors, but the principles of laundering are set forth and explained.

The book has a great deal of information about the properties of all of the chemicals used in detergency.

Love That Vintage Detergent HandBook

Have been trying to score one, but the costs even on fleaPay are a bit dear pour moi. Good to see another "vintage" soap/detergent book buff here in the group! *LOL*

Extraction between rinses also saves water and cycle time. Commercial (and domestic for that matter), H-Axis washers can give the same rinse results using fewer cycles if extractions take place between each rinse. My older Miele only does one short extraction after the third then a full after the fourth, and of course a series of final spins after the fifth (graduated then full). Newer Miele units only have the three rinses and by all accounts can do just as well. Major complaint seems to be about water levels for these rinses, but that is another matter.

High Titer Soap:

Discussed this in another thread. High titer soaps need temps >130 indeed >140 to wash and rinse well. Otherwise not only is cleaning performance reduced but unrinsed soap will carry over into the sour bath (not good), and also remain giving laundry a residue that will eventually have a whiff, not to mention "tattle-tale grey tint.

High titer soaps are those composed in whole or part of animal fats, thus some of the most common in America at one time. From home made using rendered household fats. Everything from bacon/meat drippings to whatever was left from domestic animal slaughter (for those living on farm), went into this stuff. On a commercial scale it would have been the same thing, especially after Mr. Armour discovered and promoted that nothing should be wasted from his meatpacking business.

Use of high titer soaps was one of the reasons laundry was boiled after being soaked, then hand washed. One needed that high temp water to remove all that soap.

Spin-X & The Miele

Don't know about front loaders where the final spin is >1200 rpms, but for my Miele putting items into the spin dryer after being spun at 900rpms does remove a decent amount of water (and detergent residue for that matter), from the wash.

If one is going to line dry things then it's not usually worth the bother, but for machine drying it does knock off some time and thus save energy/money.

 

[sudsman]

Tom I know the book

As I remember it has formulas for family work and hotel and hospital work, That was when we could wash with as much water as we liked and no one scolded us. And our work was CLEAN to the last sock.

 

[tomturbomatic]

Laundress, I don't know if it was my book you were talking about, but it is available on Amazon for as litle as $10.00
