Application guide for Espresso Machine Group Head Shower Screen to FDA 21 CFR / EU 1935/2004 food contact. The core duty of the type is spreading brew water evenly over the coffee puck from the espresso group head through a perforated stainless shower screen, so extraction is even across the basket. The typical industries, the how-to-specify checklist, handling practice and the exclusion cases are set out below.

Where Espresso Machine Group Head Shower Screen Is Not the Right Choice
