I'm new here, and I hope you can help me.
I'm studiying physics in Germany. Naturally we have a little lot to do, which means that we're often in a need of a delicious coffee.However we can't always take our favourite machines and brands with us. :(
This lead to the idea of integrating a coffee machine into a suitcase. (Including a water resevoir, and probably some batteries.) Therefore we took a machine apart and came up with some possible ideas. Though the whole venture took a sudden stop, as we realised that we were missing some suitable materials.
The tubes of the machine were too short! We searched a while, but we couldn't come up with some affordable tubing which would hold the conditions of boilling water AND would be food-safe. Additionally we didn't find a suitable water reservoir.
This all was around 2 years ago. We sometimes looked again for materials, but still didn't find what we needed. :(
Fortunately I discovered the Tested YT-channel a while ago and figured that you might be able to help me here.
So, can you suggest any materials and/or shops to me?
(Btw. we considered copper tubing, but we don't have the tools nor the knowledge to work with it.)
P.S.: I hope this is the right board.?
I can't help I'm afraid, but this certainly sounds like an interesting project! Let us know how you get on.
I use silicone tubing for brewing beer. It's food safe and heat resistant up to about 200 degrees Celcius.
I second the silicone tubing recommendation.
Thank you for the answers so far. Can you suggest me some particular brands and/or shops?
Futhermore, I just have seen the Robot Bartender movie. There I noticed, that some of these people used peristaltic pumps. As we might have to use some sort of pumps too, has anyone an idea where to get one?
I would suggest checking out a camper/caravan supplier or retailer for tubing they always have food safe stuff.
and for the peristaltic pumps well if your after something small and low V try an aquarium/pet store or even ebay have them
