Hygienic conveyors provide versatility
The “Flexible Screw Conveyors” from Spiroflow Systems (Monroe, NC) contain a motor-driven spiral that rotates within a sealed tube to move material efficiently and gently. The machines provide constant remixing without causing segregation. The spiral is the units’ only moving part, and this simple design enables quick disassembly and easy maintenance.
The conveyors reduce the potential for contamination in several ways. For example, the devices do not incorporate bearings and seals, unlike rigid screw conveyors. In addition, the totally sealed conveying system does not use air as the conveying medium and therefore does not require a filtration system.
Users can route the flexible conveyors around obstacles such as stanchions. The device also can be mounted on a mobile frame for use in various locations within a facility. Operators can clean the conveyors using dry, wet, or clean-in-place methods. The devices are suitable for raw-material and excipient applications.
