Engineering Excellence in Bakery Automation: FAT to 2-Lane Biscuit Sandwich On-Edge Packaging Line

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

In high-speed industrial biscuit and cookie manufacturing, the transition from primary baking and sandwiching to secondary packaging represents one of the most mechanically demanding phases of the production line. Traditional manual or semi-automated sorting frequently introduces high product breakage rates, misaligned stacks, and costly operational bottlenecks.

This technical review explores the mechanical architecture, automation control strategies, and operational efficiency of the EverSmart 2-Lane Biscuit Sandwich On-Edge Flow Packaging Line—highlighting insights from our recent Factory Acceptance Test (FAT).

1. Technical Architecture & System Layout of a Turnkey Packaging Line

A modern turnkey biscuit packaging system cannot rely on isolated machines; it requires seamless mechanical synchronization across multiple synchronized modules. The EverSmart 2-Lane system is structured into four core sequential stages:

[Sandwiching ] ➔ [Precision Counting] ➔ [Count Feeding] ➔ [On-Edge Grouping] ➔ [High-Speed Flow Wrapping]

• Precision Sandwiching & Cooling Integration: Incoming base-cakes are fed directly from cooling conveyors, paired with cream/jam deposition modules, and aligned for multi-lane discharge.

• Optical & Mechanical Counting: High-speed sensors and servo-driven control gates dynamically tally exact quantities per slug (e.g., 4, 6, or 8 biscuits per pack) without physical surface abrasion.

• Count Feeding Mechanism: Ensures a continuous, gap-optimized flow of biscuit columns into the grouping channel, preventing bridging or jamming under high-speed operation (exceeding standard line speeds of up to 100+ packs/min per lane).

2. Solving the "On-Edge Grouping" Engineering Challenge

One of the most frequent pain points for confectionery engineers is achieving stable on-edge alignment for delicate, cream-filled sandwich biscuits. If the grouping mechanism applies excessive lateral pressure, the sandwich slips or the outer biscuit cracks; insufficient pressure leads to loose stacks and failed seals in the wrapper.

Key Engineering Innovations in the EverSmart System:

1. Low-Friction Guide Rails & Pushing Jaws: Engineered with specialized food-grade polymer facings and adjustable push-fingers that synchronize dynamically with the main servo drive.

2. Omron & Siemens Servo Synchronization: Independent servo axes manage the collation pushers, ensuring acceleration curves match the exact inertia of the biscuit weight, eliminating "shingling" or tilting during transfer.

3. Pneumatic SMC Integration: Smooth pneumatic damping handles transitional lane-merging and reject functions cleanly without interrupting overall line velocity.

3. Factory Acceptance Test (FAT) Performance Metrics

During our recent factory trials for international deployment, the 2-Lane system underwent rigorous stress-testing under simulated continuous production conditions.

• Throughput Stability: Maintained consistent output across dual lanes with a variance of less than 0.1% in count accuracy.

• Sealing Integrity: Tested in conjunction with automated horizontal flow wrappers to ensure hermetic seals on multi-layer barrier film, critical for extending shelf life in high-humidity export markets.

• Changeover Flexibility: Designed with quick-release guide components, allowing plant technicians to adjust stack counts and biscuit diameters within 15–20 minutes.

4. Why Global Biscuit Manufacturers Choose Turnkey Automation

For plant directors and chief engineers, investing in an integrated primary-to-secondary packaging line yields measurable ROI across three key dimensions:

• Lower Total Cost of Ownership (TCO): Reducing reliance on manual line operators minimizes labor overhead and human-error contamination risks.

• Minimized Product Waste: Gentle handling mechanisms protect fragile sandwich cookie structures, keeping crumb and scrap rates below 0.5%.

• Scalable Footprint: The compact 2-lane inline configuration maximizes floor-space efficiency in existing facility layouts.
