Advanced Metal Detection for Food Safety in Namkeen Manufacturing

LOMA Systems , in partnership with Vedic Pac Systems Pvt. Ltd. , successfully implemented advanced metal detection systems for packaged namkeen inspection at Haldiram’s manufacturing facilities.

As one of India’s leading namkeen and snack food manufacturers with a presence in over 60 countries, Haldiram required a highly sensitive and reliable food metal detector solution to strengthen food safety standards, contamination control, and quality assurance across its production lines.

To meet these requirements, advanced IQ4 metal detection systems were integrated into high-speed namkeen packaging operations to ensure accurate detection of ferrous, non-ferrous, and stainless-steel contaminants.

The Challenge

During implementation, several operational and technical challenges needed to be addressed to ensure reliable inspection performance in a demanding snack food manufacturing environment.

Key Challenges Faced

Maintaining high metal detection sensitivity while minimizing false rejects
Integrating the metal detector within limited space on existing vertical packaging machines
Ensuring compatibility across multiple namkeen packaging line configurations
Achieving stable inspection performance despite machine vibration and product effects
Delivering quick installation, calibration, validation, and audit-ready documentation

One of the biggest challenges was installing a high-performance food metal detector system into a vertical form fill seal (VFFS) packaging line with extremely limited installation space while maintaining consistent inspection accuracy during high-speed production.

The Solution

To address the customer’s food safety and inspection requirements, LOMA Systems supplied advanced IQ4 series food metal detectors specifically designed for snack food and namkeen manufacturing applications.

Installed Metal Detection Systems:

IQ4 Vertical Fall Metal Detection System
IQ4 Wafer Thin Throat Metal Detector
Integrated reject systems for automatic contaminated product rejection

Extensive application trials and product testing were conducted to optimize:

Metal detection sensitivity
Packaging machine integration
Product flow consistency
Operational reliability under actual production conditions

As the authorized Indian partner of LOMA Systems , Vedic Pac Systems Pvt. Ltd. handled:

Technical consultation
Installation support
Calibration and validation
Operator training
After-sales service and maintenance support

This ensured seamless project execution and long-term inspection reliability.

The Results

Following successful deployment of the IQ4 metal detection systems, Haldiram’s significantly improved food safety compliance and operational efficiency across its namkeen production facilities.

Key Benefits Achieved:

Accurate detection of ferrous, non-ferrous, and stainless-steel contaminants
Reduced false rejection rates during high-speed packaging
Smooth integration with existing namkeen packaging machines
