Vacuum tumbling marinating is the norm in industrial scale food
production. Tumbling allows you to use less marinade since it tumbles
the food through the marinade, much like a front load washer uses less
water since it tumbles the clothes through it vs. a top load which has
to use much more water to submerge the clothes fully.
