Optimizing Secondary Packaging: A Complete Technical Guide to Biscuit On-Edge & Slug Packaging Syste

By Sofia Xiong | Export Vice President, EverSmart Food Equipment Limited

In high-speed industrial biscuit and cookie manufacturing, the journey from the cooling conveyor to the final retail package is one of the most mechanically demanding phases of the production line. For plant managers and chief engineers, manual handling or legacy sorting systems frequently cause high product breakage rates, misaligned stacks, and costly operational bottlenecks.

This technical guide explores the mechanical architecture, automation control strategies, and efficiency metrics of the EverSmart Fully Automatic Biscuit On-Edge Flow Packaging Line (Slug Packaging System).

1. The Anatomy of a Turnkey Biscuit Slug Packaging Line

A modern secondary packaging system cannot rely on isolated, uncoordinated units. Achieving high Overall Equipment Effectiveness (OEE) requires seamless synchronization across multiple mechanical modules.

The EverSmart on-edge packaging architecture is structured into three sequential operational stages:

• Stage 1: Multi-Lane Biscuit Feeding & Alignment SystemIncoming plain or round biscuits from the cooling conveyor are distributed and aligned into high-speed parallel channels. Advanced optical sensors and servo-driven guides ensure a continuous, gap-optimized flow without surface abrasion.

• Stage 2: Precision Rotary On-Edge Grouping Mechanism

  The most critical technical hurdle in biscuit packaging is transitioning flat-lying cookies into vertical (on-edge) slug stacks. Utilizing specialized star-wheels and rotary pushers, our system groups biscuits smoothly, protecting delicate edges from chipping or cracking.

• Stage 3: Automatic Slug Count & High-Speed Flow WrappingOnce grouped into precise counts (e.g., 6, 8, or 10 pieces per slug), the stacks are seamlessly transferred into horizontal pillow wrappers for hermetic film sealing, maximizing shelf life.

2. Engineering Advantages: Why On-Edge Slug Packaging Matters

For global confectionery and bakery brands, switching to an automated on-edge flow packaging line yields measurable ROI across three key dimensions:

• Minimized Scrap and Breakage: Traditional sorting often results in high crumb rates. Polymer-coated guides and gentle rotary transfer mechanics keep product scrap below 0.3%.

• Quick-Format Changeovers: Engineered with modular, quick-release components, plant technicians can adjust stack counts and biscuit dimensions within 15 to 20 minutes, drastically reducing downtime.

• Compact Footprint: The streamlined multi-lane inline configuration maximizes floor-space efficiency in existing facility layouts.
