Load the belt
Fillets enter on a belt. Their footprint and spacing determine how much belt area each product needs.
SPIRAL FREEZER · HIGH-DENSITY PROCESSING
eFeS Spiral
A longer freezing path on a smaller floor area.
FSK / 02eFeS Spiral
A longer freezing path on a smaller floor area.
02 / 03
Follow the spiral
The belt winds around a drum. Stacking the path vertically gives the product time in the freezer without extending the line across the building.

Size for the product
Pizza illustrates why product diameter and height matter. Belt width, tier spacing and travel time are selected together; total belt length varies by project.
