There is a coffee machine (also makes tea and hot chocolate) in my workplace that uses individual packets (not pods) for the drinks. I do not know what the mechanism is for turning that into a drink (beyond that hot water is run through the packet) and am not authorized to take the machine apart to look. I imagine there must be something that punctures the packet, like in a Keurig machine; whether that part gets heated in the brewing process is unclear.
The company says that its coffee and tea packets are kosher, but notes that the ones for hot chocolate and latte mix-ins are not. So if none of my coworkers drank cocoa and latte it'd apparently be fine, but that's not the case. I'm aware of this question about Keurig machines, but I don't know if the mechanism is the same so don't know if the answer there would apply to this kind of brewer.
What would I need to do to be able to use this shared device in a kosher manner?
(Of course I'm not seeking p'sak. I just want to know what the issues are -- has anybody already addressed this?)
