Food Processing Equipment & Cutter Design

Custom helical cutter shaft engineered to produce consistent snack dimensions across production lines while maintaining throughput and minimizing equipment modifications.

​

Project Description

KS Projects engineered a custom helical dough-cutter shaft for industrial snack food production to solve product-sizing inconsistencies between two manufacturing lines.

An existing straight-blade rotary cutter was producing oversized products that created compatibility issues with downstream packaging equipment.

The objective was to maintain the higher throughput of the newer production line while producing dimensions consistent with the existing equipment.

A new cutter shaft was developed using replaceable food-grade stainless steel blades positioned along a 45° helix. The blade geometry and helix pitch were optimized to provide smooth, consistent cutting at production speed.

The retrofit design retained existing mounting points, shaft dimensions, bolt patterns, and drive interfaces wherever possible, reducing installation time and eliminating the need for major equipment modifications.

Sanitary design principles were also incorporated through smooth surfaces, accessible geometry, and easy disassembly for cleaning and maintenance.
