Biro counter top vacuum tumblers are the tools you need to create the value added. You can marinate most meats and fish in less than 20 minutes, so you can make those value added products in a minimum amount of time. Vacuum marinating distributes the marinade evenly throughout the product, so you get full flavor in every bite. It also adds water and tenderizes the product, so it cooks faster and is juicy and flavorful. These tumblers are incredibly easy to use, too. It only takes 5 minutes to load the product, water, and marinade, and it runs for about 20 minutes while you do something else. When a batch is done, you only need 5 minutes to empty the drum and wash it out, and you’re ready to do another batch.
