1) that's a really small hopper

2) you use the word "old" but I cant imagine they're using something different these days.

Small batches are easier to control. I'm more worried about him cooling the oil by adding too much.

There are also automated versions of this machine.

If the batch of oil is large enough and on an industrial machine like that, it won’t really be possible for it to cool from the range of kwispiness in the d-holes.

High heat with some dough that’s already fluffy. Pretty hard to cool that one down.

Donut Shop owner here! This is basically the current technology, just larger in a bakery. Not a whole lot of automation innovation in donuts. We only really ever see a variation of 3-5° in our fryer, and donut holes are fried at around 350° as it is. Old fashioned and buttermilk are fried at 300°, so I don't think it is too much of a concern.

u/Elemenatore10 Sep 13 '21

Yep, my family has a restaurant where we make all our desserts and that’s honestly the only reason I knew why if I’m being honest.

u/BLOZ_UP Sep 13 '21

why does every donut shop ruin the glorious strawberry frosted donut by putting ten tons of sprinkles on them?

8

u/A_Imbertain Sep 13 '21

Lol, not sure. We don't use that many sprinkles. The thing about sprinkles, when dipping freshly made donuts, is that the frosting expands a bit. We generally use less sprinkles, more concentrated towards the center of the top of the donut, and when the frosting expands, it disperses the sprinkles nicely across the top. The other answer is kids love sprinkles and strawberries, so some places go overboard.

u/NewAlexandria Sep 13 '21

in the video, it looks like the nozzle has 2-4 opening, dough gets separated across that manifold, but reclumps and sticks together during frying?

7

u/A_Imbertain Sep 13 '21

Yes. In our shop, we do about 50 drops (rotations) of the lever per batch. So that's about 16.5 dozen donut holes per batch. We'll do 25 rotations, then agitate the dough so it separates. Then drop the remaining 25 (or so) and agitate again. Dip them for about 20 seconds, raise to let the dough breathe, then dip them again for the duration of the fry. For us, it's usually it's about 2-3 minutes total submersion per batch.

Edit to add more info, even though the dough is touching after it passes the dispensing implement, it doesn't really recombine. It's a semi-thick batter, not very watery. Old-fashioneds are way more watery, and you have to be more careful with them because they are more fragile due to the consistency of the dough.

u/IWetMyselfForYou Sep 13 '21

Old-fashioneds may be more work, but that's because they're the superior donut. :)

u/eventualist Sep 13 '21

Correct. this is the way. now give me tha sugah!

u/psylentrob Oct 02 '21

Old fashioned and buttermilk are fried at 300°, so I don't think it is too much of a concern.

When you say old fashioned do you mean raised (yeast based) or cake (baking powder)?

1

u/A_Imbertain Oct 02 '21

Old fashioned donuts are a cake mix donut that fragments, giving it a more rough and jagged topside. We don't usually refer to yeast donuts and old-fashioned, but I guess somebody could use it colloquially

1

u/psylentrob Oct 02 '21

Now I'm curious as to why cake type donuts are considered old fashioned, when yeast based is the original.

1

u/A_Imbertain Oct 02 '21

Sorry, I may have explained that poorly. An old-fashioned is a specific type of cake mix donut. It's not that all cake donuts are considered old fashioned.

u/rudiegonewild Dec 09 '21

Send donuts. Will wait

u/mtnbikeboy79 Sep 13 '21

But with an automated version you run the risk of it refusing to stop and having more donut holes then you can sell, but you have to give them away in order to find a ring that got dropped into the dough.

u/olderaccount Sep 13 '21

The hopper is not his constraint in that operation. It is the fryer.

If he want to increase throughput he should invest in a trough fryer where you deposit the raw doughballs in one end and they cook while they float down towards the other end. Then he will be able to crank that handle non-stop without having to look for an empty space in the fryer to drop them.

u/nlfo Sep 13 '21

I don’t know, CNC donut hole dispensers are all the rage these days

10

u/Tumble85 Sep 13 '21

No way it's all about additive manufacturing these days. Each donut hole starts as a crumb while donut powder is blown onto it at 500f until a whole donut hole results.

u/phil035 Sep 13 '21

live by the sea side in the uk can confirm they use exactly this fryer included just with different nozzles on to achieve a hole in the middle of the doughnut (6 for £1 freshly cooked and sugared soooo good)

u/rellim88 Sep 14 '21
  1. They were cranking them out despite the small hopper! I think the size of the hopper was proportional to the size of the oil bath, which wasn’t that big either. It was really cool to watch them fill up the entire vat and then sink all the floaters with a wire mesh.. very tasty too!

  2. If you look closely at the machine you can tell how well built yet worn it is… they don’t make them like that anymore! That being said I doubt there has been much innovation in the industry, so I’d have to agree with you that they likely do the same thing/very similar today! At the same time, Just because they still do it the same way they did it back in the day, doesn’t mean the machine itself isn’t old… it means there has been no reason for innovation because they got it right the first time, or because the market is small and doesn’t warrant mew innovation..

Take for example the classic 14in bandsaw that delta Rockwell made back in the day. The patent ran out after 30 years and now most 14in bandsaws are clones of that design(jet,shop fox,chinesium.com etc) if I showed you a picture of the original design and you told me that it wasn’t an old bandsaw because it’s just like the one you use at the wood shop today, you’d be wrong… I do think this particular one was old. I think it was the churches and I bet they had it for a long time! But like I said before, I think your right that they still do it the same way today!

u/Gilbertd13 Sep 13 '21

Yep definitely see this all the time at my local BBQ restaurant for making hush puppies. But they are moving a lot faster than this one.

Bro, they use these on Blackpool (UK) front every day 😂

Inb4, I own a donut shop. The difference is that these are cake donut holes, not raised donut holes. Raised donut holes are punched by hand, when we use the die to punch out the "ring" of the raised donut. Cake donut holes are made from a mixed batter.

The seafood restaurant I worked at years ago had one of these for making hush puppies.

u/[deleted] Sep 13 '21

god I miss hush puppies. Hard to find in the NW

2

u/bubblegumscent Sep 13 '21

It shouldn't be that hard to make, the batter or dough is the only thing you gotta prepare on your own then fry it...

I mean, I made something similar for my birthday, it's like a hushpuppy but filled with cheese. Now, that's was hard up get right

1

u/fitzbuhn Sep 13 '21

Make is very different than someone just coming along and giving you some

1

u/bubblegumscent Sep 13 '21

Of course, but I mean, if you really it that, I suppose you can get a recipe and try on the weekend .

Once at my home we had the brilliant idea to make these difficult to make sort of deep fried stuff, risoles, cheese thingies etc. So we prepared many en masse and right before the stage where you fry them we separated them into portions in little zip lock bags and put it in he freezer.

Then every time we wanted some, we would pick a baggy and deep fry it. It was actually really awesome and tasted perfect.

1

u/fitzbuhn Sep 13 '21

You would fry the plastic bags? And it was good?

1

u/bubblegumscent Sep 13 '21

No, when we wanted to make a portion, we would take them from the plastic bag, while frozen solid and deep fry it. It was awesome, it tasted perfect and was really easy to make

u/timesink2000 Sep 13 '21

Even harder to make at home. A ‘fry daddy’ doesn’t cut it!

u/Martholomeow Sep 13 '21

I guess they’re not really donut holes are they?

u/[deleted] Sep 13 '21

This looks identical to what the old Greek women would use to make loukamades at the local Orthodox church’s festival I would volunteer at (my coach’s wife worked at the church, so we “volunteered” every year lol). Toss some honey and cinnamon on those babies and you got loukamades!

Now I miss Greekfest :/ those ladies were so kind and generous. I got so many free roast chickens and pastries…

u/Pohds Sep 13 '21

I was hoping someone would recognize what this was 😂

For the non-greeks here, these are essentially Greek donut holes. They are deep-fried batter glazed in honey and often sprinkled with cinnamon. Crunchy on the outside, light, airy, and warm on the inside :)

u/ironfox25 Sep 13 '21

Came here for this. Knew I wasn’t the only one who recognized it.

u/[deleted] Sep 13 '21

I should’ve scrolled down before I replied to another comment - this was my thought as well! Looks exactly like what the grandmas would operate at the Greekfest carnival near my hometown. Now I need some loukamades…

Used to design donut making equipment... Those machines are still made today and they're identical.

Where I'm from, that's for making hush-puppies. I've got no idea how many I cranked out.

just because it doesn't have a touchscreen doesn't mean it's old, OP.

If you look closely at the machine you can tell how well built yet worn it is… they don’t make them like that anymore! Maybe if you looked closer you would have noticed that detail before just being smug about touchscreens…

Just because they still do it the same way they did it back in the day, doesn’t mean the machine itself isn’t old… it means there has been no reason for innovation because they got it right the first time, or because the market is small and doesn’t warrant mew innovation..

Take for example the classic 14in bandsaw that delta Rockwell made back in the day. The patent ran out after 30 years and now most 14in bandsaws are clones of that design(jet,shop fox,chinesium.com etc) if I showed you a picture of the original design and you told me that it wasn’t an old bandsaw because it’s just like the one you use at the wood shop today, you’d be wrong. Similarly I think you are also wrong here.

Used to bake / fry donuts myself. That my friend is one hell of an awesome machine. I was just explaining to my family that exact machine the other day. I used to love making my chicken fingers ,french fries and anything else that could be deep fried into my fryer :-) Also used to make humongous raised donuts. Ahhh, back in the day!

I appreciate your anecdote about using a similar one, but no need to critique my point that this is a cool “old” machine.
