Coffee in a case - Where do I get food-safe materials?

  • Hello guys,

    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.

  • @UschanDeLucca:

    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

  • This would work -
