Vacuum Tumblers


The patented Blentech ‘wave-vane’ system overcomes the disadvantages of other designs by delivering strength in effective end-to-end mixing, tumbling and rapid discharge. The ‘wave-vane’ system is excellent for a wide variety of products. The smooth curvature of the helical vanes is gentle on products such as bone-in chicken, bone-in hams, and beef rounds with minimal product degradation during tumbling. The gentle end-to-end mixing assures even distribution of curing liquids and marinades throughout sectioned and formed products while maximizing protein extraction for better binding of whole-muscle products. Yields of cooked and smoked products are improved because the brine solution is stabilized evenly throughout the cell structure of the meat during the vacuum marinating process, resulting in improved liquid retention in comparison to other vane designs. The gentle, yet rapid vacuum cooling to as low as 40°F (5°C) of a variety of products such as rice, grains, pasta, and staged rice dishes such as biryani and pilau are all applications that make Blentech vacuum tumblers a true asset to a production space. Products exit Blentech tumblers, rapidly chilled, free-flowing, and ready for packaging. Furthermore, with the addition of cryogenic capability, IQF freezing of vegetables and ready-meals is a breeze.
