Improving Liquor Packaging with Automated Foreign Particle Detection and Label Orientation Verification

foreign particle detection

In high-speed manufacturing environments, ensuring product quality is essential to maintaining brand integrity and meeting regulatory standards. A leading manufacturer of liquor bottles faced challenges with manual inspection processes, which led to missed foreign particles and misaligned labels. Scanflow partnered with them to implement an automated visual inspection solution, improving both operational efficiency and product quality at the packaging stage.

Key quality control issues at their packaging line:

  • Inconsistent Manual Inspections: Manual checks were prone to fatigue and human error, resulting in missed foreign particles and incorrect label placement.
  • Labor-Intensive and Time-Consuming: The manual inspection of bottles, including the hard-to-reach areas such as the bottom, was time-consuming and required substantial manpower.
  • Difficulty in Detecting Subtle Defects: Small foreign particles, cracks, and label misalignments were difficult to detect manually, especially on opaque or colored bottles.
  • Throughput Limitations: Manual processes could not keep up with high-speed production, affecting efficiency and output.
  • Inconsistent Quality Across Shifts: Variability in inspection quality from shift to shift and operator to operator led to inconsistent product quality.

Scanflow deployed its automated visual quality control system, using high-definition cameras to detect foreign particles and verify label orientation on the production line. The system was integrated seamlessly with the existing packaging process, ensuring there were no disruptions.

Capability Function
Foreign Particle Detection Detects debris, insects, and other foreign particles inside sealed liquor bottles.
Label Orientation Inspection Verifies correct label placement and alignment on bottles after automated labeling.
End-of-Line Camera Integration Utilizes existing IP cameras for capturing real-time images of bottles on the conveyor.
Real-Time Defect Detection Flags defective bottles for immediate rejection from the production line.
Data Sync with ERP Synchronizes inspection data with the client’s ERP system for batch tracking and regulatory compliance.
  • Foreign Particles Detection: Two high-definition cameras capture images of bottles on the conveyor, scanning for foreign particles such as dust, insects, or breakages. If a defect is detected, the system triggers an alarm, stopping the conveyor and allowing operators to manually remove the faulty bottles.
  • Label Orientation Inspection: After label application, the system checks if the labels are correctly oriented. Any misalignment triggers an alert, prompting operators to send the bottle to the rework station for correction.
Impact Area Before Scanflow After Scanflow
Inspection Speed Manual inspection was slow and prone to errors Automated inspection sped up the process
Product Quality Inconsistent inspection quality Increased consistency and fewer defects
Operational Efficiency High labor costs and slower production Reduced labor, faster throughput
Compliance Inconsistent documentation Automated data capture for full traceability
  • Reduced Labor Costs: Automating the inspection process minimized the need for manual labor, resulting in reduced operational costs.
  • Improved Product Quality: Scanflow’s system reduced defects by catching errors at the end-of-line, preventing wrongly labeled bottles from reaching consumers.
  • Increased Throughput: The automated process allowed for higher production rates, without compromising quality.
  • Regulatory Compliance: Digital logs of inspection results were automatically recorded, ensuring full traceability and adherence to industry regulations.

In industries like liquor packaging, in-line quality inspection is critical to ensuring that each product meets the required standards. Labeling errors or incorrect label placement can lead to regulatory violations, product recalls, and potential consumer safety issues. By replacing manual inspection with automated visual inspection, Scanflow helped Tilak Nagar Industries enhance their quality control during the production line, ensuring products are packaged correctly and meet all regulatory requirements.

Scanflow’s solution proves that automated defect detection and label orientation verification during in-line inspection are essential for maintaining operational efficiency, product integrity, and compliance in high-speed manufacturing environments.

Top 5 Industries that can’t afford to ignore AI Visual Inspection to ensure Quality Control

Quality control is a fundamental part of modern production, not a post-process task. As product lines become more complex and output volume increases, manual inspection methods are falling behind. Inconsistencies, sampling limitations, and human fatigue reduce reliability, and in many industries, the cost of missing a defect can far outweigh the cost of detection. 

Automated visual inspection using AI offers an operational alternative. These systems continuously monitor parts, packaging, and assemblies to identify non-conformities in real time. Unlike human-led visual checks, they work consistently at production speed and are not limited by field of view or repetition. 

Here are five industries where AI quality control is not just helpful but critical for managing cost, safety, and operational flow.

1.Automotive Manufacturing

What’s at Risk? 

In automotive production, even a minor undetected fault can cause downstream failures, recalls, or safety risks. As vehicles become more modular and software-controlled, part accuracy and fitment consistency are critical. 

Where AI Quality Control Fits 

  • Identifies missing or misaligned parts during sub-assembly 
  • Validates correct placement of components in high-speed conveyor lines 
  • Checks paint variation, fastener placement, and body alignment at multiple checkpoints 

Automated inspection removes dependency on sampling and enables every part to be checked in line. This lowers rework, prevents shipment of defective components, and supports consistent assembly logic across models.

2.Electronics and PCB Assembly

What’s at Risk? 

Electronics manufacturing deals with micro components, layered boards, and solder joints. Errors can lead to immediate product failure or degraded performance over time. Manual checks are often insufficient for dense assemblies and repeated inspection tasks. 

Where AI Quality Control Fits 

  • Scans PCB surfaces to verify component position and orientation 
  • Detects solder joint quality and solder bridge formation 
  • Identifies missing, rotated, or offset elements 

Automated systems offer consistent board-level checks at the speed of production. They also reduce reliance on microscope-based checks and help log inspection outcomes across batches.

3.FMCG and Consumer Goods

What’s at Risk? 

In fast-moving consumer goods, inconsistent packaging, labeling issues, or contamination can lead to rejected batches and brand damage. Human inspection during high-speed production often misses subtle or recurring defects. 

Where AI Quality Control Fits 

  • Confirms cap placement, seal presence, and fill level in bottling and packaging 
  • Verifies label orientation, print quality, and product completeness 
  • Detects mold defects, foreign particles, or missing items in packaged kits 

Visual inspection systems work continuously across shifts, detecting recurring packaging issues without slowing output. This supports error-free delivery and reduces quality-based returns or retailer rejections.

4.Pharmaceutical Manufacturing

What’s at Risk? 

Pharmaceutical packaging and labeling must comply with strict regulations. Errors can lead to rejected shipments, non-compliance penalties, or in extreme cases, health risks to patients. 

Where AI Quality Control Fits 

  • Verifies printed content on labels such as batch codes and expiration dates 
  • Checks blister pack alignment, completeness, and sealing 
  • Detects leaflet presence, carton folding accuracy, and box orientation 

These checks are conducted without manual intervention and can be scaled to suit both static packaging stations and fast conveyor lines. Data from inspections can also support documentation required for regulatory audits.

5.Metal and Steel Processing

What’s at Risk? 

In metal processing, dimensional accuracy and surface consistency are essential. Surface-level flaws and forming inconsistencies may not be visible until much later in the process, making early detection valuable. 

Where AI Quality Control Fits 

  • Identifies surface defects such as cracks or incomplete finishes 
  • Monitors part shape and size during cutting or machining 
  • Detects process deviation during rolling or extrusion 

AI inspection systems installed at forming or finishing points help reduce scrap, minimize second-pass processing, and ensure that specifications are met before moving parts forward for final use. 

Why Manual Inspection No Longer Scales 

Across all five industries, manual visual checks present common limitations: 

  • Inspection fatigue across long shifts 
  • Inconsistent results across operators 
  • Limited coverage (sampling vs. full unit inspection) 
  • Delayed defect detection after the next process step 

AI visual inspection helps resolve these by introducing structured, programmable checkpoints. The system can be trained to detect specific non-conformities, linked to plant logic, and deployed without disrupting upstream or downstream flow. 

Adoption Model: Where AI Quality Control Typically Starts 

Most manufacturers begin by deploying AI quality control at one of three stages: 

  1. Conveyor-based inspection during active production to identify defects in motion 
  2. Static inspection stations for verifying critical components between process phases 
  3. End-of-line inspection to confirm completeness before packaging or shipment 

These systems work with standard cameras, smart devices, or edge-mounted infrastructure and integrate with MES or quality management software for centralized visibility. 

Conclusion 

The shift toward structured, automated inspection is not driven by convenience but by operational need. Missed defects create bottlenecks, safety concerns, and cost overhead that manual systems struggle to contain. 

Scanflow’s AI quality control platform enables production teams to run real-time inspections without changing their existing infrastructure. Whether deployed inline, at dedicated visual checkpoints, or at dispatch gates, it supports fast, reliable inspection to help ensure product consistency and reduce downstream risk.
