Compared to marinating meat the traditional way, Model RMM-45 meat marinator gives you better results in less time. It uses vacuum pressure and a tumbling action to dramatically reduce the time needed to marinate proteins. The flat edge of the barrel tenderises the meat as it tumbles, and the vacuum removes air from the chamber so marinade can deeply penetrate the meat. This vacuum and tumbling action simulates overnight marination in as little as 20-25 minutes. The RMM-45 commercial vacuum food marinator is ideal for restaurants that are low on cooler space but still need proteins marinated, or to supplement an overnight marination program.
