I am trying to design a simple automated bar to mix a drink, like a Jack & Coke. I would like to use 2 pumps 1 for the Jack and a separate one for the Coke. I am stuck on what is the best way to pump a carbonated liquid from a 2 liter bottle into a glass? I would like to do it fairly cheap, and still have a good flow rate.
How would I go about pressuring the 2 liter bottle? I would like to do it cheap if possible. This is for a proof of concept / demo for a potential client.
With a [u]peristaltic pump[/u], the only thing the liquid comes in contact with is the tubing. This type of pump very common in food/beverage and medical applications.
This is for a proof of concept / demo for a potential client.
Every bar & restaurant has a system like that, so I'm not sure what you're trying to "prove".
Everything has to be approved for food use (you can't use cheap stuff from the hardware store or eBay), and my other concern is if you can build something that's as reliable and maintainable as a commercial unit.
I'm not sure about this, but in an restaurant or bar the equipment might be supplied free by the Coke distributor.

Carbonated water is already pressurised.
That is why its fizzy.
If more pressure is needed carbon dioxide (food grade) must be used.
