At interpack China 2026, Techik will present its Whole-Chain Food Safety and Quality Assurance System at Hall W4, Booth W4C09. The exhibition runs from November 16 to 18, 2026, at the Shanghai New International Expo Centre (SNIEC). The showcase brings together inline inspection and sorting equipment, six quality assurance subsystems, and Easy Link, Techik’s quality management IoT platform.

A food manufacturer such as a bakery processing company may inspect incoming ingredients, sort baked products after the oven and check seals, labels and weights after packaging. Each station addresses a different issue and generates a different set of results. Techik’s system pairs equipment at those checkpoints with software that brings equipment data together. Production and quality teams can use this approach to define what needs to be checked at each stage and review how the process performs across the line.

Six Subsystems from Raw Materials to Finished Products

Techik organizes the system around six quality tasks. The equipment used at each point depends on the product, the production environment and the acceptance criteria.

1. Foreign Contaminant Detection. Techik’s X-ray inspection, metal detection and optical sorting technologies address different types of foreign material. An inline metal detector can check for metal contamination, while X-ray inspection can detect suitable dense contaminants such as glass or stone. Optical systems can address visible surface contaminants on exposed products. At the exhibition, the pipeline X-ray system for sauces and the multi-view X-ray system for canned foods will show how the inspection method changes with the product and its presentation.

2. Raw Material Sorting and Grading. Incoming materials such as grains, beans and nuts can vary in size, color, shape and surface condition. Optical sorting can remove visibly defective items and separate acceptable material into grades based on the processor’s specifications. Placing this check before mixing or further processing gives manufacturers a way to manage variation at intake.

3. Finished-Product Sorting, Grading and Analysis. Finished products have their own acceptance criteria. A bakery may need to remove biscuits with dark baking marks, missing corners or distorted shapes. Techik’s multi-view AI optical sorter examines baked goods from multiple angles. For a different type of quality requirement, Techik’s dual-energy X-ray system analyzes fat content in meat. The two applications show how finished-product quality can involve both visual grading and composition analysis.

4. Packaging Seal Inspection. A seal can be compromised by product trapped in the sealing area or by visible defects such as wrinkles or misalignment. Techik will feature two configurations for bagged products. One pairs separate vision and X-ray stations, with a wide-channel configuration available for side-by-side inspection. The other integrates X-ray and vision into a compact, dedicated seal inspection unit. Applications include transparent and opaque bags made from materials such as PE plastic, metallized film and aluminum foil.

5. Packaging Compliance Inspection. Vision technology can check whether the correct label is present and whether printed information, such as a date or lot code, is readable and in the expected position. On a line that handles multiple products, these checks help identify packaging mix-ups or printing errors after a changeover and before dispatch.

6. Weight Compliance and Grading. Dynamic checkweighers identify products outside their preset weight limits as they move along the line. Weight grading can also separate products into defined weight bands. For bags, boxes and other finished packs, Techik will present a compact system that integrates X-ray inspection and dynamic checkweighing, with optional vision inspection for external packaging checks.

Easy Link Connects Quality Data Across Checkpoints

Easy Link combines production data analysis and production scheduling in an industrial IoT platform. Techik’s exhibition materials specify support for more than 400 mainstream equipment communication protocols. The platform supports equipment connectivity, quality traceability, analytics and alerts, giving teams a way to review data across inspection and sorting stations.

Consider a bakery where the optical sorter records an increase in appearance defects while the checkweigher continues to report weights within limits. The two readings describe different aspects of quality. Reviewing them together can help the team decide whether to investigate the baking or handling stage. A change in seal-related rejects would direct attention to a different part of the line.

Hygienic Design for Food Production

The showcase will also feature hygienically designed equipment for different cleaning routines. The multi-view AI optical sorter for baked goods uses a 304 stainless steel construction, IP66 protection and a quick-release belt to help operators access areas where crumbs or oil can collect. An IP69K-rated X-ray inspection system will also be featured for demanding washdown applications.

Founded in Shanghai in 2008, Techik develops inline inspection and sorting systems for food and agricultural processing. Meet the team at Booth W4C09 to discuss your products, current quality checkpoints and which inspection results would be most useful to connect across your line.
