Bottle Cap Unscramblers specification should start with the real closure.
Bottle cap unscrambling is often the missing link between manual cap placement and a reliable automatic capping cell. The best solution should take into account bottle stability, cap style, speed, line controls and operator access for cleaning and changeover.
For a better buying decision, the useful comparison is not only hopper size or headline speed. It is how the feeder behaves with your closure, how the capper receives the cap and how easy the line is to run after changeover.
The safest specification route is to start with real closures, target output, line photos and the exact point where the cap must be presented. That avoids choosing a feeder on a generic speed figure that does not match the cap or capper.
