  • Patent number: 5988049
    Abstract: Fluid is efficiently and uniformly removed from successive bodies of a product by a combination of finely perforated wedge shaped hollow blades sufficiently long as to fully penetrate the product body depth, a series of vacuum suction tubes arranged within the blades for pressure differential removal of accumulated free fluid from the lowest point of the product body, a pneumatic or other cylinder to provide linear motion, position control, and cyclic variation in applied load for introduction and withdrawal of each blade and suction tube assembly to and from successive bodies of the product, and mechanism allowing the blade and suction tube assembly to travel only in a defined linear path for repeatable unimpeded entry to and withdrawal from successive product containers, each of which is mechanically fed into and precisely held in a series of locations directly beneath wedge and suction tube assemblies.
