I can help assert some bits of it. Having been a cog in the McMachine, I've learned a bit about various suppliers and hardware and pieces of the soda fountain puzzle. https://www.pentair.com/en-us/landing-pages/mcdonalds.html https://www.pentair.com/en-us/landing-pages/mcdonalds.html These folks supply 90% of McD's in the United States with their filtration requirements. That then just gets fed into a (fairly mundane, actually) bag-in-box soda syrup system, just scaled up to the demands of a large fast food restaurant. The only special thing is - yes, the Coca-Cola syrup is delivered by bulk tank instead of the BIB. The bulk tank? It's the McBulk! https://files.chartindustries.com/10718219_McDonalds_Syrup_Installation_Manual.pdf https://files.chartindustries.com/10718219_McDonalds_Syrup_I... Other than that it's your bone standard Cornelius fountain setup; though a bit beefier carbonator system. Cold chilled water hops through the carbonator, then to the fountain, where it's then dispensed in the correct ratio required. Coke NORMALLY is 5:1 ratio, but the McCoke is 4.75:1. If you wanted to somehow replicate this at home, you could, though it'd be a costly endeavor.
