To facilitate the ever increasing demand for quick recipe changes, TSM has developed the auto-clean blender. With the ‘auto-cleaning’ integrated feature it is possible to change from one recipe to another without any cross contamination of materials. It allows for rapid order and colour changes while limiting the machine downtime. The blender is no longer the limiting factor, instead, the purge time of the process unit determines the time required for colour change.
On every order change, this enables cleaning of all pellets from the entire blending system using our uniquely designed 5-step control process. The process entails not only automatic emptying of the hopper bins, but entire cleaning from the loader down to the mixing chamber. In addition, the ‘auto-clean’ blenders offer a specially designed automatic purge by-pass valve to provide a back-up material supply to the process machine. Level sensors, combined with TSM control technology, supervise and control the cleaning and purge by-pass functions.
Further to the above fast changeover times, the auto-clean blender also provides a safe working environment as it is no longer necessary for the operator to climb on top of the machine to clean the system.
