BlendSave™ is LIAD’s patented centralized blending and weighing system. BlendSave creates new homogeneous masterbatch from a combination of mono-masterbatches (SPD’s).
BlendSave operates by simultaneously weighing all needed resins and SPD’s for each recipe within its 14 weighing chambers, each of which is dedicated to a specific raw material, and then releases the entire batch into a common funnel for conveying to the corresponding extruder. LIAD achieves superior batch uniformity by placing a particular mixer within the free fall hopper connected to the inlet of each extruder.
For masterbatch manufacturers with tens of different SPD’s LIAD integrates multiple BlendSave units into a single system linked via a PC-linked controller to establish a fully automated production of new masterbatches from combinations of SPD’s. The funnel of each of individual BlendSave of the integrated system releases the weighed recipe into a second common funnel. The complete batch is then sent via an automatic manifold and tubing to the corresponding extruder.
When considering the possibility of integrating 3 BlendSave units to handle 42 ingredients, the total required floor space is only 15 sqm.
