This is a breadcrumbs production line in a client's factory. The model of the breadcrumb extruders is TSE70, and we can see there are 4 extruders in the breadcrumbs processing line. 

 Actually, a TSE95 model breadcrumb extruder can almost reach the output that the 4 TSE70 extruders have. 4 TSE70 extruders' cost is higher than one TSE95 extruder, and the floor occupation is larger than 4 TSE70 extruder. Why did the customer choose the 4 TSE70 extruder? That is because there are many advantages to using 4 small extruders over one big extruder. First, if the output needed to decrease, the customer can stop some of the extruders. Second, 4 extruders can produce different kinds of breadcrumbs or different products such as croutons, and snacks. Certainly, there are also many advanges of using a big breadcrumb extruder.
