Kurkure and Namkeen Packing Machine: How Multihead Weighers Handle Fragile and Irregular Snacks
India's Kurkure and Namkeen Market
Kurkure and namkeen are two of the most beloved and commercially significant snack categories in India. The kurkure category, which encompasses extruded corn puff and wheat-based snacks in various shapes and flavours, was pioneered as a mass-market product and has grown into a multi-thousand-crore category with both national brands and regional producers competing for consumer attention. The namkeen category is even larger, encompassing a vast and regionally diverse range of products including sev, chivda, gathiya, chana dal, groundnuts, mixture, bhuji, aloo bhujia, and dozens of regional varieties that collectively represent the largest snack segment by volume in India.
Despite their very different product characteristics, kurkure and namkeen share a common set of packaging challenges that make them among the most technically demanding products to pack accurately and efficiently. Both are fragile and can break under excessive mechanical stress. Both are irregular in shape, meaning that individual pieces vary in size and weight. Both have bulk densities that vary between product types and even between production batches. And both are packed in weight-declared consumer packs that must comply with Legal Metrology regulations for packaged commodities.
The multihead weigher packing machine was developed specifically to address exactly these challenges, and its adoption in the kurkure and namkeen packing machine space has transformed what Indian snack producers can achieve in terms of fill accuracy, production speed, and product quality.
Why Conventional Weighing Technologies Fail for Kurkure and Namkeen
To understand why the multihead weigher is the right technology for kurkure packing machine and namkeen packing machine applications, it is helpful to understand why conventional alternatives fail.
Volumetric filling, which dispenses product by volume rather than weight, is fundamentally unsuitable for kurkure and namkeen because the bulk density of these products varies too much for volumetric control to deliver acceptable weight accuracy. A batch of sev that has been freshly produced and is still warm will have a different bulk density than the same sev after it has cooled and compacted. A batch of kurkure produced from one production run may have slightly different piece sizes than the next batch, changing the bulk density. Volumetric filling would require constant manual recalibration to compensate for these variations.
Linear weighers, which use a single weigh cell and a series of vibration channels to accumulate product to a target weight, are an improvement over volumetric filling but are limited in speed and accuracy for highly irregular products. The combination weighing principle of the multihead weigher, which evaluates all possible combinations of portions held simultaneously in multiple weigh heads and selects the combination closest to the target weight, overcomes this limitation.
How the Multihead Weigher Packing Machine Solves Kurkure and Namkeen Challenges
Combination Weighing Accuracy
A multihead weigher packing machine for kurkure and namkeen typically uses 10, 14, 16, or 20 weighing heads, each holding a small portion of product. The central computer continuously evaluates all possible combinations of the product portions in the active heads and identifies the combination that most closely matches the target fill weight. With 14 heads, for example, the number of possible two-way, three-way, and higher-combination options runs into thousands, giving the algorithm enormous flexibility to find a combination that hits the target weight precisely. For a 40-gram pack of namkeen, fill accuracy of plus or minus 1 gram or better is routinely achievable, well within the Legal Metrology tolerance for that pack weight.
Gentle Product Handling
The multihead weigher disperses product from a central dispersion cone across radial channels to the individual weigh heads using vibration rather than mechanical conveyors, paddles, or augers. This vibration-based product distribution is among the gentlest mechanical product handling methods available in packaging machinery, and it is specifically important for fragile snack products like kurkure and thin sev that would fracture under the impact forces of alternative filling mechanisms. The kurkure filling machine based on multihead weigher technology delivers the target weight into the pack with minimal product breakage, preserving the snack quality and visual appeal that consumers expect.
Speed
A kurkure packing machine based on a multihead weigher can achieve production speeds of 60 to 120 packs per minute for standard 20 to 50 gram retail packs, a throughput level that manual packing or simple single-head weigher systems simply cannot match at commercially viable labour costs. For namkeen packing machine applications where a wider range of pack sizes is common, the multihead weigher’s rapid algorithm recalculation between packs enables consistent high-speed performance across the full pack weight range.

Multi-Product Flexibility
One of the most commercially important advantages of the multihead weigher packing machine for namkeen producers is its ability to handle the enormous diversity of namkeen product types. A namkeen producer who makes sev, chivda, chana dal, and mixture combinations can pack all of these products on the same multihead weigher machine with product recipe changeovers that take 15 to 30 minutes, compared to the multiple hours of manual calibration and adjustment that less flexible filling technologies would require. This product flexibility is a major determinant of production efficiency for the regional namkeen producers who collectively represent a substantial share of India’s snack market.
The Complete Kurkure and Namkeen Packaging Line
A commercial kurkure packing machine or namkeen packing machine installation typically consists of more than just the multihead weigher and the VFFS collar type packing machine. The complete production line includes a bucket elevator or inclined conveyor to elevate product from production floor level to the multihead weigher inlet height, a distribution conveyor that feeds product evenly across the top of the multihead weigher, the multihead weigher itself with its radial distribution, weigh head, and combination weighing systems, a collar type VFFS packing machine below the multihead weigher that forms the pouch from a reel of flexible film, receives the weighed charge, and produces the sealed finished pack, a date coding and batch printing system, a nitrogen flush system for products with extended shelf life requirements, and a finished goods conveyor for pack transport to the cartoning or manual packing station.

Addressing Specific Challenges in Kurkure Packing
Kurkure-type extruded snacks present some specific additional challenges beyond the general requirements of fragile snack packing. Their angular, irregular shape means they can interlock and bridge in hoppers and distribution channels if the vibration amplitude is not correctly calibrated. Their tendency to generate fine dust during handling can contaminate sealing surfaces if not managed by appropriate dust extraction at the fill zone. Their high oil content can affect the adhesion of some film types, requiring attention to film selection and sealing jaw temperature calibration. A kurkure packing machine from Fair Pack Machineries is set up and calibrated by the company’s technical team to address each of these product-specific factors before the machine is commissioned.
Addressing Specific Challenges in Namkeen Packing
The namkeen packing machine challenge is primarily one of product diversity. Different namkeen types have dramatically different piece sizes, shapes, and densities. Sev, which consists of very fine extruded threads, has a very high specific surface area and is particularly fragile. Thick sev, gathiya, and chana dal are more robust but have different flow characteristics. Mixture combinations combine multiple components with different densities and sizes in a single weighed charge. The multihead weigher handles this diversity inherently, because the combination weighing principle is insensitive to product type as long as the weigh head portion size is appropriate for the individual piece size. For very fine or very small products, weigh head bucket volumes can be adjusted. For coarser, larger pieces, wider-mouth buckets are used. Fair Pack Machineries provides application-specific configuration advice and tooling selection for each namkeen product type.
