What is your current cleaning (CIP?) process?
We use a large number of strongly flavoured liquid products and our standard CIP cycle has no problem handling these, so before looking to add anything you may want to examine how effective your current process is.

Usually when you want to remove the odor of coffee in coffee mugs/thermal cups, you add baking soda. it works well to remove that. You can possibly contact your cleaning/sanitation contractor and ask them what options they have for any chemicals that can remove the coffee odors.

Currently we use lye, acid and hot water to cleaning machine for milk liquid. However, we don't know how remove the coffee flavor on the surface equipment totally before changing to milk liquid.

We can do examination but what parameter should we check and how do we know that is ok or not...

If it is a closed-system, I'd just run water through after CIP, and run a QC on the water. If the water quality is good, i.e. sensory evaluation, pH, specific gravity and refractive index would be a good minimum. Transmission or NTU is also a good idea. It's also a good extra check on how the CIP perform.
