Food Processing NDT Inspection
In modern food processing lines where throughput speeds are exceptionally high, conventional metal detectors fall short because they cannot spot non-metallic contaminants like glass, stones, or dense plastics. Karma Innovations fills this critical safety gap with HACCP-compliant and AERB-approved online digital radiography equipment. Operating at optimized, food-safe voltage levels, these automated systems "see through" bulk or finished packaging in real-time. This protects consumers, ensures compliance with strict international food safety standards, and shields brands from costly product liability claims.
Critical Contaminants & Defects Detected in Food Products
Karma’s intelligent, real-time image integration and processing software instantly identifies sub-surface foreign bodies and structural issues:
- Non-Ferrous Contaminants: Glass shards (from jars or light fixtures), stones/pebbles from the field, and calcified animal bones.
- Metallic Contaminants: Minute fragments of stainless steel, iron, or non-magnetic metals from processing blades, sieves, and machinery wear.
- High-Density Plastics & Rubber: Broken conveyor belt fragments, gaskets, or packaging seals embedded in the food matrix.
- Mass & Void Estimation: Checking for missing components inside a sealed package or detecting under-filled or hollow sections in bulk items.
Food Products Inspected Under This System
Karma’s conveyorized, automatic PLC-controlled systems are highly customizable and easily integrate directly into raw processing or final packaging lines:
1. Packaged Foods & Ready-to-Eat (RTE) Meals
- Pouches and Foil Packets: Scanning sealed ready-to-eat curries, instant noodles, and snack packs for contaminants—even through metallized foil packaging that blinds traditional metal detectors.
- Packed Rava, Flour, & Spices: Inspecting dense, finely milled powders for clumps, foreign particles, or machinery debris before final sealing.
2. Grains, Pulses, & Bulk Agriculture
- Rice and Pulses Sorting: High-throughput scanning of bulk grains on fast-moving conveyor belts to eliminate tiny stones, glass bits, and dense field mud clumps.
- Seeds and Nuts: Detecting internal voids, insect infestations, or structural damage inside bulk-packed nuts and seeds.
3. Bakery & Confectionery
- Chocolates and Candies: Verifying the presence of fillings, identifying missing pieces in a tray, and detecting foreign particles in bulk chocolate molds.
- Biscuits and Bread Packs: Real-time screening for broken machinery pieces or baking debris inside large-volume baked goods lines.
Key Components of the Food X-Ray System
To maintain seamless operation inside a fast-moving food factory, Karma's systems rely on a strictly integrated set of industrial components:
- Food-Grade Automated Conveyor: Built entirely from easy-to-sanitize, food-safe materials complying with strict hygiene standards.
- High-Stability X-Ray Source & Sensor Array: Tailored low-energy radiation generators paired with ultra-sensitive digital detectors that yield high-contrast images without affecting the food’s taste, shelf life, or nutrition.
- PLC-Controlled Automatic Rejection Module: A high-speed pneumatic flap, air-blast, or pusher mechanism that automatically ejects defective packets at rates up to 60 packets per minute without stopping the production line.
- AERB-Approved Radiation Shielding: Heavy-duty, self-shielded mild steel enclosures that guarantee absolute radiation safety for factory operators working nearby.
