Abstract
A vacuum tumble mixer is provided with a hollow drive shaft at one end thereof. The hollow drive shaft provides access by means of a probe to the cylindrical center section of the vacuum tumble mixer in order to inject the ingredients to be mixed, to introduce cooling material such as liquid nitrogen or carbon dioxide, and finally to permit cleaning fluids to be circulated about the interior of the tumbler while the tumbler is rotating. The use of the hollow shaft greatly improves the efficiency and operation of the tumbler for vacuum massaging and tumble chilling of meat, poultry, seafood and other products that are mixed at the commercial level.
