HELP my smoke generator don't smoke !

[titi cold smoke]

Hi!
I made this generator, and I use it with oak wood chips.
The problem is that the wood chips go out very fast.
And there is very little smoke.

What is the problem? The pump? The chips? the pipes?
Thank you for your answers.

2nd pic looks like the copper pipe goes into the black pipe
is that so?

Nice build!
You did put a port in for it to suck the smoke with the venturi, right?
From what I can see, the copper pipe looks like it might be a little snug in the outlet pipe.

Other than that, maybe try some pellet fuel. I've been experimenting and with a round screen cylinder I can put in some Hickory pellets and light it with a torch (at the bottom corner) and they will continue to smolder completely.
So, as long as your venturi is right, I'd try some pellet fuel for go. The chips might need some help because they don't always pile up tight enough for the 'fire' to catch the other pieces.

Edit in: I think you need a smaller tube feeding in the air at the tip. In a picture, simular to this:

You would get more smoke using a Tee on the copper with a small piece of pipe facing down,and going into
the black pipe for the venturi to work.The air from the pump will go straight and suck the smoke up with it
Nice buils

The copper pipe needs to be smaller.... inserted into the black pipe with space around the copper pipe.. Air turned on... pressure drop sucks in the smoke... air flow pushes the smoke out...

Look up "venturi" and how to make...

Thanks
Are you talking about a Tee like that?
Do you think that the problem comes from the copper pipe too big?
thank you very much guys

Welcome to SMF
Didn't see you introduce yourself in roll call..
Hope you get your smoke generation going..
Happy Holidays.

This adaptation will make the smoke generator work....

 

[titi cold smoke]

Ok, thank you, it's very nice. I'll test this when I go home in a few days.
To introduce myself, I'm French I and I'm a new cold smoker.
Here is my smoker. It's built in Montpellier maple (french maple). On this pics, it's the first smoke generator : it's a simple metal box in which I put charcoal and wood chips. I will adapt the new system instead of this one.
To smoke, I use juniper, oak, plum tree and french maple.
I can also show you a little video if you want.
I smoke salmon, trout, hadock, duck magret. And I cook fish soups with leftovers, and other fishes of course.
