What's The Best Way To Grind Beef? | The Burger Lab

Grinding Tips: To minimize smearing, cut meat into 1- to 2-inch chunks and place them in a single layer on a sheet tray or large plate in the freezer for about fifteen minutes before grinding. Grind in batches no larger than a half pound for a 10-cup food processor. Pulse rather than constantly running the grinder to get a more even grind.

Mechanical Disruption Methods: Grinding

In single-step disruption experiments, conical glass homogenizers liberate about half as much enzyme as compared to larger more expensive high throughput homogenizers. Glass tissue grinders are approximately 30-40% as efficient as the best methods (see Fig. 20), but the relative cost is fractional ($70 vs. $15,000).
