How to Produce kurkure: A Complete Manufacturing Guide
Corn sticks,Kurkure also known as Kurkure or Cheetos-style snacks, are a popular extruded puffed snack made primarily from corn grits or cornmeal. They are crispy, flavorful, and widely enjoyed as a ready-to-eat snack. This article provides a step-by-step guide on how corn sticks are produced, covering raw materials, processing methods, and key equipment.
1. Raw Material Selection
The main ingredient for corn sticks is corn grits or cornmeal . Additional ingredients may include:
- Starches (potato, tapioca) for texture improvement
- Seasonings (salt, cheese powder, spices)
- Oil (for frying or coating)
- Fortification agents (vitamins, minerals for nutritional enhancement) .
2. Production Process Overview
There are two main methods for producing corn sticks: frying and baking.
A. Fried Corn Sticks Production Line
Process Flow:
- Mixing – Corn grits are blended with water and minor ingredients in a mixer.
- Extrusion – The mixture is fed into a rotary-head extruder, where it is cooked under high pressure and temperature (120-180°C), forming irregularly shaped sticks .
- Debris Removal – A vibrating screen or roller sieve removes broken pieces.
- Frying – The extruded sticks are deep-fried in a continuous fryer (170-190°C) for crispiness.
- Seasoning – A rotary drum coater evenly applies oil and flavor powders.
- Cooling & Packaging – The sticks are cooled and packed in moisture-resistant bags .
Equipment Used:
- Mixer → Screw feeder → Rotary extruder → Elevator → Vibrating sieve → Continuous fryer → Seasoning drum → Packaging machine.
B. Baked Corn Sticks Production Line
Process Flow:
- Mixing & Extrusion – Similar to the fried process, but with adjusted moisture content.
- Drying/Baking – Instead of frying, the sticks pass through a multi-zone belt oven (120-160°C) to reduce moisture to 3-5%.
- Seasoning & Packaging – Same as the fried version but with less oil .
Equipment Used:
- Mixer → Extruder → Conveyor dryer → Seasoning system → Packaging machine.
3. Key Equipment in Corn Stick Production
- Rotary Extruder: Uses a copper alloy die for wear resistance and produces twisted shapes .
- Continuous Fryer/Oven: Ensures uniform cooking (frying at 170°C or baking at 150°C).
- Seasoning Drum: Applies flavors evenly (cheese, chili, barbecue, etc.).
- Packaging Machine: Uses nitrogen flushing to extend shelf life .
4. Quality Control & Shelf Life
- Moisture Control: Final product moisture should be <5% to prevent sogginess.
- Texture Testing: Crispiness is measured using a texture analyzer.
- Shelf Life: Properly packed corn sticks can last 6-12 months if stored in dry conditions .
5. Variations & Market Trends
- Flavors: Cheese, spicy, sour cream, and seafood are popular.
- Healthier Versions: Baked, low-fat, or fortified with protein/fiber.
- Automation: Modern lines allow one operator to manage multiple extruders .
Conclusion
Producing corn sticks involves extrusion, frying/baking, seasoning, and packaging. Manufacturers can choose between fried (crispier) or baked (healthier) versions based on market demand. With advancements in extrusion technology, corn sticks remain a profitable and scalable snack food product.
