Motorizing the apple grinder

[MrCaboola]

I'm interested in building a grinder and I want to be able to grind lots of apples really fast. I'm thinking of having a skill saw motor (2hp) to power the grinder, but they run at around 5400 rev/min. I'll need gear reduction to slow the angular velocity. So what's is the max angular velocity you would suggest for the wood cylinder cutter? I'm thinking I might need to put some medal bearings and gears to help with the higher speeds.

[Matthiaswandel]

I wouldn't recommend anything faster than about 600 RPM, but people have run apple grinders much faster. But you end up getting too much backsplatter. At 600 RPM, one ton of apples doesn't actually take that long.

Uyou are aware the seeds contain cyanide? And the worst thing you can do is grind them well before ingesting, even chewing them is a bad idea

[Matthiaswandel]

FYI - people used to eat apple seeds. They survived.

Also, ever tried to squeeze the juice out of apple seeds?

[ADyingFetus]

@homosapienssapiens19 Apple seeds contain very little cyanide. Not nearly enough to make you even feel sick.

I love the trick of cutting the pulley on the table saw. Do V belts have a standard degree of angle from the sides inward? Also, you have these nice motors that you say you got out of the trash. You must dumpster dive all the time!

Would the grinder be more effective if you cut the pushing block to match the diameter of the cutting spindle? Like So.....---( O

wtf



[Elliottslingsby]

Imagine getting your fingers caught in that...

[WorldStove]

yay! home made scrumpy on the way

[darkfrei2]

I think it's wrong side rotation.

[chembilllee]

Hi Matthias, I'm interested in the jig (set up) you used to carve the large V pulley on the table saw, any details you can give me would be appreciated. BTW, I'm much more of picture person than a word person so any little sketch would be helpful. Thanks, Bill Lee

[jimpikles]

what's the mashed apple for?

[apatientspider]

Why couldn't the gears be used with the pump motor? Was it too fast?

[apatientspider]

Your sister's children will have a great time turning that crank; I know how kids are always drawn to the handcranked blower for my blacksmith's forge. :-)

[vestraya]

why would you do that?! what did those apples do to you >:(

[loocow1554]

@TheLegoboulder eeeewwwww gross

[NoobTamer]

He is grinding apples to make cider.

[x86cowboy]

How do you deal with the seeds? Do some escape into the output?

[InsaneVender]

Dont think id use a porous material like wood for food handling equipment, haven for Bactria.

[apatientspider]

@InsaneVender Wood is perfectly safe for non-meat food handling use as long as it is kept clean with periodic washing. Besides, the acid content of apples is quite sufficient to deter bacteria growth.

[koppadasao]

That one can skin your hand, if you aren't careful.

[EyeOnTheTV]

making cider?



[loocow1554]

@TheLegoboulder i know

[Sodabowski]

I second asserta's comment.

Yet another really cool machine :)

[IH1940HAY]

It looks like Motts Sauce Apple Co is still safe, LOL

Good development and we like to see the R&D, to know that not all your designs work right out of the box.

Thanks

[loocow1554]

@Bomberzone1745 nope

[loocow1554]

this is cool but why would you want to shred apples?

[theSIRcrew]

poor apples

[aserta]

You should shape the part that pushes the apple on the cylinder shaped as a hollowed out portion, like removing a cylinder from the block.

[deweys]

What did you seal the wood with? Tung oil?

[Matthiaswandel]

Canola oil

[rhblakeman]

@Matthiaswandel For food use mineral oil is best - canola and other vegetable oils will get rancid with time where mineral oil won't.

[woodsprout]

@Matthiaswandel Ha ! Of course: "CANadian Oil, Low Acid"

Is this what you used to lubricate the cutter drum bearing too?

Personally I like the idea of using vegetable oils in place of petroleum where possible.

And when paste wax is needed I prefer Howard Citrus Shield.

I appreciate your videos, they help me remember I am not alone in my way of thinking.

[TheBlacksabbathfan9]

@Matthiaswandel yes, I too have had problems with fan motors and there low torque I believe it is a safety feature

[Nippe0000]

You are cool dude!!

[Pbmaster11]

where do you find all of these motors?

[littlestworkshop]

@Pbmaster11 I'd guess from old fans, bread makers and a pump from the garbage :)

[Matthiaswandel]

Well put :)
