Meat marinators and vacuum massagers are commercial food-preparation machines used to season, tenderise and improve the consistency of meat before cooking or further processing. They work by tumbling products with marinades, brines or spices; vacuum models can help the seasoning penetrate more evenly while also supporting a controlled preparation process. These machines are suited to butcheries, delicatessens, catering kitchens, restaurants and small-scale meat processing operations preparing poultry, pork, beef or other cuts in batches.

Key distinctions include vacuum versus non-vacuum operation, batch capacity and the intended volume of production. When selecting a unit, consider the quantity prepared per cycle, available workspace, the types of product being marinated and the cleaning routine required between recipes.
