Kurkure, a brand of corn puffs launched in India in 1999, has become one of the country‘s most recognizable snack brands. Named after the Hindi word for “crunchy,” the product is known for its distinctive twisted, irregular curl shape and intense spice blends. While the brand markets itself as a “Tedha” (twisted) snack, the industrial process behind its production is a carefully engineered sequence of mixing, rotary extrusion, frying, and seasoning. This article examines the key stages of Kurkure’s manufacturing process based on publicly available industry documentation.
Raw Material Composition
The foundation of Kurkure is a blend of grain flours. According to product labels from Tesco and Voila, the primary ingredients are rice flour, maize flour (cornmeal), and chickpea flour. Vegetable oil, typically a blend of sunflower and corn oil, is also incorporated. A project report from the Uttar Pradesh government lists corn meal, rice meal, edible vegetable oil (palm oil), gram meal, spices, condiments, salt, sugar, and milk solids as the core components.
The seasoning system is complex. A Masala Munch label reveals a spice blend containing salt, onion powder, sugar, flavourings, potassium chloride, coriander powder, black rock salt, garlic powder, cayenne pepper, cumin, citric acid, fenugreek, ginger, black pepper, and colours including paprika extract and plain caramel. The presence of milk solids means the product is not vegan.
The Rotary Head Extrusion Process
The defining feature of Kurkure production is its rotary head extruder, which differs fundamentally from conventional single- or twin-screw extruders used for standard puffed snacks.
How It Works
The process begins with corn grits being moisturized in a vertical mixer with water and oil. This mixture is then fed into the rotary head extruder. Inside this machine, the material is subjected to mechanical action between two rotating plates, typically made of brass. One plate rotates and features three to six blades plus grooves, while the other plate has grooves only.
The action of these blades creates the necessary pressure and heat to achieve gelatinization of the raw materials at approximately 260°F (127°C). Expansion and forming occur in the narrow gap between the two plates. As the material is squeezed and twisted, it emerges through the die as an irregular, curled shape—the signature Kurkure form. Cutting knives mounted on the outer edge of the rotor then cut the extrudate into desired lengths.
Industry documentation emphasizes that moisture content, feed screw speed, and the type of brass used for the extruder heads control the expansion and texture of the final product. This is a critical quality control point.
Frying and Oil Removal
After extrusion, the shaped Kurkure pieces are conveyed to a continuous fryer. The frying step serves multiple purposes: it reduces moisture content, creates the final crispy texture, and develops the golden-brown colour through Maillard reactions.
The frying system typically features automated temperature control for uniform frying. After frying, the product passes through a vibrating de-oiler, which uses high-frequency vibration to remove excess surface oil. This step ensures a less greasy mouthfeel and improves the product‘s shelf stability.
Seasoning Application
The seasoning stage is where Kurkure’s diverse flavour profiles are established. The fried and de-oiled pieces move through a seasoning line, which may consist of a single drum, double drum, or octagonal seasoning machine depending on the production configuration.
Seasonings are applied by spraying or tumbling. The industry documentation indicates that seasoning is best applied while the product is still warm, ensuring effective adhesion of the spice powder to the snack surface. For products like Masala Munch, the seasoning blend is designed to deliver what the brand describes as an “explosion of spicy Chatpata taste”.
Complete Production Line Configuration
A typical industrial Kurkure production line follows this sequence:
- Flour Mixer – blends grain flours with water and oil
- Screw Conveyor – transports the mixture to the extruder
- Rotary Head Extruder – forms the twisted curl shape
- Conveyor/Separator – transfers product and separates oversized or misshapen pieces
- Continuous Fryer – cooks and crisps the product
- Vibrating De-oiler – removes excess oil
- Seasoning Line – applies flavour powders
- Packaging Machine – fills and seals bags, often with nitrogen flushing for freshness
Some manufacturers offer baked alternatives to the fried version, replacing the fryer with a multi-layer oven. However, the rotary extrusion principle remains the same.
Production Economics
For those considering small-scale production, a government project report provides baseline figures. A machine with an input capacity of 25-28 kg per hour yields approximately 15 kg of finished product after accounting for 40% wastage. This output translates to roughly 1.8 million packets annually at 20 grams per packet. The required land is approximately 250-300 square feet, with 3-4 workers needed for operation.
Conclusion
Kurkure‘s manufacturing process is defined by its unique rotary head extrusion technology. The interaction between two brass plates creates the pressure, heat, and twisting action that produces the brand’s signature irregular curl. While the ingredient list reveals a relatively straightforward grain-based formulation, the engineering behind the shaping, frying, and seasoning stages is what distinguishes Kurkure from conventional puffed snacks. As with any industrial food product, precise control of moisture, temperature, and timing is essential to achieving consistency at scale.
