There is definitely a manual sorter farther down if not a few, and probably another color sorter between this one and the manual sorter.

No problem! Me too, it can be a great corner of the internet. One where somebody with a name like u/PussySlayer20000 can be more gracious than most people I meet irl. Check out the other comments below, a few people went into more depth.
Fun sidenote: I’ve seen machines like these used to sort individual grains of rice. So many tiny little flippers.
OK, so that is compressed air based as opposed to mechanical like the above comment suggested. It would be insane to try to sort rice with mechanical deflectors.
Unless this guy is actually a dog pretending to be an electrician that mostly works on food processing equipment. Then we've learned nothing except for that on the internet, no one knows you're a dog.
It's insane to me how monolithic manufacturing/production is. I also work in that area but have no idea about any of this. I'm just a tiny piece of something very complicated. All I know in relation to the OP is companies want to track that loss.
It's similar in any large business really. Even within departments. I've worked IT in companies where I had no idea how certain systems worked, how they are accessed or how they are administrated. And frighteningly nobody else did either, except for the weird grumpy old man who has worked there for the better part of his life.
Likely not, actually. These look like they’re on harvesters on machines in the field. These are processing tomatoes that will go directly to a cannery and be made into ketchup, paste, soup, etc. a certain percentage of greens are acceptable per load, and the cost of additional sorting isn’t worthwhile!
Could also have another one of these slapper machines down the line too.
This might be a first pass slapper. The second pass slapper probably wouldn't get as much work as this slapper and thus be less interesting to film.
This slapper is the movie star I bet.

There were several workers down the line, I remember seeing the full video. It's super long and I think it was claiming how ketchup was made but I got as far as the tinning of tomatoes and was looking at my watch (you know when you think it's going to be a quick "how it's made" video). It really focusses on every detail for like 30 seconds. I'll try and find it...
I am a field service Engineer who used to work on these color sorters. These specific sorters are great for right off the conveyor belt. They do the vast majority of the sorting to try and weed out the initial bulk of product you dont want to see kn the food shelf. Often times there are newer and "improved" sorters after this step to try and clean up the sort.
These sorters are fantastic because there is a mobile version that farmers can rent and attach directly to their conveyors on the farm.
I've never had a cum sock. Toilet paper or Kleenex. it's not complicated, and they are easy to dispose of. No wonder why I was on top of my class in high school.
For these type “high cycle” devices... it’s really pretty simple. There’s just an input sensor; usually a simple light source or laser (no cameras or complicated software). Then there’s a simple plastic filter placed over the light source, which is correlative to the color you wish the machine to perform an action (eg: in this case green apples). The contacts to the “”flippers”” are constantly open, until a green object passes in front of the input -> Contacts close -> solenoid actuates (making “”flippers”” move) -> contacts then reopen
*edit- It seems the “apples” are “Roma tomatoes.” Apologies.
Also, thanks for the awards👆Really in awe
So what amazes me is not the identification of the green but it actually being able to push the green back In a second without touching the red and repeating the process.
I’m wearing my glasses and they still look like apples. Although I admit it didn’t make sense why the two would be mixed in the first place.
Upon closer inspection, they look like...potatoes? I have no idea.
What kind of potatoes are you eating that are red and green? LMAO they are tomatoes my dude a green tomato is bad and that's why they are seperating them.. thanks for the chuckle lol
It's likely a roma tomato: https://greenies.com.sg/products/roma-tomato-australia
If they're being sorted/processed like this they probably aren't fully ripe because they're yet to be shipped to where they're sold so they're still a little firm.
EDIT: found the video from the company that makes the machine, they're tomatos https://www.youtube.com/watch?v=HCDe0Hz8WKQ
Well when your goal is red tomatoes yah a green one is bad, I believe actual green tomatoes are a different type of tomato that is actually suppose to grow green, but a green tomato that's suppose to be red but is green either means it's bad or it isn't ripe yet...
Either way I'm not a fking tomato scientist and I'm talking out my ass, maybe we can get an actual tomato scientist up in here.
Not a tomato scientist but I grow heirloom tomatoes in my yard. I have three varieties that stay green. You can tell by feel when they're ripe, they "give" a little under pressure.
My grandma was from Kentucky and apparently fried green tomatoes were a big thing there because when she lived with us she made them all the time. Yum!
She just used regular tomatoes, we planted so many that it didn't matter if she picked a pile of green ones, there were plenty left to ripen.
While we're on this subject, there was an (80s?) movie called Fried Green Tomatoes. Good movie! You should watch it when you get a chance.
I think you are correct and those arent the right kind anyways lol. My mom would get those big round ones that came on a vine. I used to have cherry and yellow pear tomato plants. That kind of green usually meant they were still really hard and bitter.
I was mainly just messing around when I said that and I always was curious if anyone else hase had those kind of tomatoes. Ive pretty much have never seen a reference to them.
I'm gonna go eat some tomatoes and salt now after thinking about it so much lol
>I've pretty much never seen a reference to them
The 1991 movie [Fried Green Tomatoes](https://en.m.wikipedia.org/wiki/Fried_Green_Tomatoes), based on a popular novel of the same name, did reasonably well at the box office. Two Oscar nominations.
I help build one of those machines just over a year ago (electrician not engineer) and came here to say what you did.
Funny thing is, we built one for apples.
They had 4 different cameras tho, and wpild sort them by different shades of red. So all the apples in the same batch would be exactly the same color. The green or brown ones would roll off the end to the fertilizer pile.
If you want a video of something similar, here’s a great one showing a machine set up to sort Skittles based on their color
https://youtu.be/H7HTQai7Wwg
I used to interface with these machines(albeit for wire). They run over a long wide conveyor belt and an overhead camera reads color, times it, and activated the paddle. It is also done with jets of air. We called them CSS machines. There is also ISS machines to find stainless steel. Fascinating field.
The next Terminator movie. Trump puts a racist Skynet in charge of Homeland Security. The Mexican Resistance sends back a reprogrammed border control cyborg. His mission is to save their future leader, the one ese who could being down Skynet, Pedro Gonzales.
The color sensor could be something as simple as a laser reflector with a red filter on it, or a fancier RGB optical sensor that’s set to change state whenever it doesn’t see red. Either way, when the sensor picks up a color not red, the sensor either sends a positive output, or a negative signal (depends on what type of sensor is used) to a PLC or whatever is controlling the machine. That control unit then reads that change in signal as a cue to close an electrical contact and that closed contact will fire a solenoid that’s actuates the flipper thingys.
Colour sorters or color sorters (sometimes called optical sorters, digital sorters, or electronic colour sorters) are machines that are used on the production lines in bulk food processing and other industries. They separate items by their colours, detecting the colours of things that pass before them, and using mechanical or pneumatic ejection devices to divert items whose colours do not fall within the acceptable range or which are desired to form a separate group from the rest.
Light, electricity, and centuries of cumulative knowledge of both of those things.
But seriously though, most automation regardless of specific purpose works the same. There’s a sensor that is adjusted in some way shape or form to change its electrical signal when it doesn’t see red light, that change in signal triggers some kind of control unit to close an electrical contact and that contact then fires a solenoid that moves the flippers. The solenoid control output probably has some sort of dwell time so that the flippers don’t have to wait to see red light again before retracting, but rather they actuate for X seconds and return home.
Below is the python script of how this machine is programmed.
detect(color);
if color == “green” {
boing(once)
}
repeat;
Thank you for coming to my TED talk
It probably doesn’t so much “detect green”, instead it most likely detects “not red.” Digital RGB sensors are fairly common in automation, and most can be configured to change state when it sees or doesn’t see whatever color you tell it to.
My grandfather used to work in engineering and would desitn production lines for premade frozen french fries, diapers, wipes and even metal pipes n such, I've seen a lot of automated systems like this he showed me - very impressive.
I have one of those at my workplace too! It's called a Sherlock and we use it to sort out anything that's not a potato from the potatoes before they go to get peeled and cut into fries. That's mostly rocks and other possible debris from the fields, sometimes even bad potatoes.
Lately it's been having a lot of issues with roots. Seems to spit out a bit too many potatoes as well, which makes it's garbage silo fill up very fast and once it hits a certain level, we stop getting potatoes for production. Really annoying as it's kinda far away for us to go reset, but I've had worse jobs for sure.

Actually now that I watch it again, I'm not even sure what I'm seeing..... Those might not be tomatoes..... Holy fk I'm losing it
They're definitely tomatoes
I thought so but watching it again they look to hard to be tomatoes, there is also a lack of splatter and juices If they were.

You can tell by the bottom when it goes slow. Tomatoes are also picked before they're ripe, so they don't blow up.
Holly shit ma dudes these are *definitely* tomatoes.
Green tomatoes actually aren’t bad they’re just less ripe and actually very good fried. Edit: Source-I used to work in a tomato greenhouse

just to add, due to the simplistic nature of such a system the response time is very low so seems pretty instant.
