Thorough mixing is achieved over a short length of material flow with the Spiroflow ITS inline twin screw continuous proportional blender. It is steplessly adjustable for any blend ratio and is designed for use with any free free-flowing, granular, flake or pelleted materials. Accuracy of the Spiroflow ITS is to 2%, depending on material and application, making it suitable for a wide range of uses in the food, chemical, building products and other process industries specifications.
The Spiroflow ITS incorporates a novel principle in that the feed of the secondary ingredient is introduced directly into the center of the flow of the primary ingredient. The unit has two rotating spiral type conveyors of different diameters. The steel tube of the smaller conveyor is located within the spiral of the other. As the diagram shows, the tube of the smaller conveyor extends beyond the inlet hopper of the larger conveyor. This ensures that the flow of the minor ingredient is introduced into the primary one at the optimum point for thorough mixing. Stratification of different ingredients, which occurs with other types of mixer, is avoided by the unique design of the Spiroflow ITS due to its mechanical action.
Spiroflow ITS blenders are made up of standard sized Spiroflow rotating spiral conveyors and can be designed for any required throughput up to a maximum of 10 tons per hour.
Hygienic versions of the Spiroflow ITS with quick release connectors for ease of disassembly and cleaning are available for use in the food, chemical and pharmaceutical industries.
