Of course, such a complex project can only be profitable if changeovers are fully optimized. And this is again an argument for weight filling. As explained earlier this technology is naturally clean process. It also provides the simplest product circuit, which saves time and product at the end of each batch when draining as well as time and water on cleaning operations. Weight is also the easiest parameter to calibrate when products show different physical characteristics. Production setup is thus much simpler with weight filling than with other technologies. Another time savings benefit.
