Kontinuer has developed several lines for the transport of solid raw material, blood, fat or water. The screw conveyors are the most common solution for transporting solid materials between the different equipment that make up the processes. The hoppers act as buffers between the different processes to adjust the feeding pace at each stage. In all cases, the design and material characteristics vary according to particle size, temperature, and other characteristics. Lamella pumps are also used (to transport solid raw material, usually crushed), Helical Pumps, Piston Pumps and Centrifugal (to transport blood, fat or water) or Volumetric Pumps (to feed decanters or centrifuges). Tanks are used at different stages of the process. In some situations, pneumatic transporters are necessary, with ventilators and filters for specific types of meals.
