The Portakeeper Anti-Popcorning Device is an essential tool for any coffee enthusiast using a DF64 coffee grinder. It prevents coffee bean pieces from disrupting the main flow of whole beans, helping to stabilize the grind rate and improve the consistency of the ground coffee.

This device is designed to fit perfectly on the lower end of the bellow on these grinders. It has a simple yet effective design, with a perfect shape that fits neatly underneath the bellows without hampering them in any way.
