The Volkmann VS pneumatic vacuum conveying system transfers powders, pellets, and other bulk food ingredients from storage to an extruder in measured amounts. Transferring materials as pulsed slugs in preset weights or volumes, the sanitary conveyor eliminates the use of manual extruder loading, along with its potential for errors and contamination. The enclosed vacuum conveyor can discharge the ingredients into a feeder, hopper, or mixer, or directly into the extruder inlet as a sealed raw material transfer system without exposing sensitive materials to the plant environment.
Suitable for conveying food, petfood, nutritional, and other ingredients for extrusion, the Volkmann VS conveyor transfers multiple ingredients from bulk bag unloaders, sack tip stations, silos, feeding hoppers, and drums in multiple locations for feeding into a single extruder or continuous mixing processor. Powders, such as fine sugar and salt in particle sizes as small as 0.1 µm, as well as chocolate chips, candies, nuts, and berries up to several in. in size are transferred safely and gently.
