The exact production configuration depends on the equipment design and the desired product characteristics.
4. Detailed Manufacturing Process of Bugles-Style Snacks
Step 1: Raw Material Preparation
The first step is preparing the cornmeal, starch, and other ingredients.
Manufacturers should inspect all raw materials to ensure that they meet food-grade quality requirements. Cornmeal should have suitable particle size and moisture content to support stable extrusion.
Powdered ingredients are usually passed through a screening system to remove impurities and lumps.
After inspection, the ingredients are weighed according to the established production formula.
Accurate weighing is important because variations in ingredient proportions may affect the expansion rate, texture, and final product quality.
Step 2: Mixing
The prepared ingredients are transferred into a mixing machine.
Cornmeal, starch, and other dry ingredients are blended evenly before water is gradually added.
The purpose of mixing is to distribute moisture uniformly throughout the material and create a consistent mixture for extrusion.
Several factors should be controlled during this stage:
- Water addition rate
- Mixing time
- Raw material proportions
- Moisture distribution
- Ingredient uniformity
If the moisture content is too high, the material may become difficult to control during extrusion. If it is too low, insufficient plasticization may occur, resulting in unstable product formation.
Proper mixing provides a stable foundation for the following extrusion process.
Step 3: Extrusion and Cone Shaping
Extrusion is the most important stage in producing cone-shaped corn snacks.
The conditioned corn mixture is fed into an extruder, where the screw conveys, compresses, mixes, and heats the material.
Under the combined effects of mechanical energy, pressure, and temperature, the starch-containing mixture becomes plasticized.
The material is then forced through a specially designed forming system to produce the characteristic cone-shaped structure.
Unlike ordinary puffed snacks, cone-shaped snacks require specialized forming equipment or molds to create their distinctive hollow cone appearance.
The following factors influence the quality of the extruded product:
- Screw configuration
- Screw speed
- Barrel temperature
- Material moisture content
- Die design
- Extrusion pressure
Manufacturers need to optimize these parameters according to the raw material formulation and equipment specifications.
Step 4: Cutting and Initial Shaping
After extrusion and forming, the continuous or partially formed material is divided into individual snack pieces.
The cutting system must work in coordination with the extrusion equipment to maintain consistent product dimensions.
At this stage, manufacturers should inspect the cone shape, wall thickness, and overall appearance.
Poor cutting accuracy or unstable forming conditions may result in irregular shapes and uneven product sizes.
Step 5: Drying
Freshly formed corn snacks generally contain more moisture than finished products.
Therefore, they need to undergo a drying process before frying or baking, depending on the selected production technology.
A continuous belt dryer is commonly used in industrial production.
During drying, hot air circulates through the product layer and gradually removes excess moisture.
The main purposes of drying include:
- Reducing moisture content.
- Stabilizing the product structure.
- Preparing the snacks for subsequent frying or baking.
- Improving consistency during further processing.
- Reducing the risk of excessive deformation.
Drying temperature, air velocity, product loading thickness, and drying time should be properly controlled.
Uneven drying may lead to inconsistent expansion, cracking, or differences in final crispness.
Step 6: Frying or Baking
After drying, the cone-shaped snacks can be fried or baked according to the selected production method.
Frying Method
Frying is commonly used to produce a rich flavor and crispy texture.
The dried snack pieces are transferred into a continuous frying machine. During frying, heat causes further moisture evaporation and helps develop the final crunchy structure.
Important frying parameters include:
- Oil temperature
- Frying time
- Product moisture content
- Oil circulation
- Oil quality
If the oil temperature is too low, the snacks may absorb excessive oil and become greasy. If the temperature is too high, the product surface may become too dark or develop an undesirable flavor.
After frying, a de-oiling machine can be used to remove excess surface oil.
Baking Method
Some manufacturers may choose hot-air baking to produce a different product profile.
Baking uses controlled hot air rather than immersion in frying oil. It can help reduce added oil, although the resulting texture and flavor may differ from those of traditional fried products.
The choice between frying and baking depends on the target market and desired product characteristics.
Step 7: Seasoning
Seasoning is an important stage in determining the final flavor of cone-shaped corn snacks.
After frying or baking, the products are transferred into a seasoning machine, usually a rotating seasoning drum.
During operation, the drum continuously rotates to distribute seasoning powder over the snack surfaces.
For better adhesion, a controlled amount of edible oil or suitable seasoning coating may be applied before adding the powder.
Popular seasoning varieties include:
- Original salted flavor
- Cheese flavor
- Barbecue flavor
- Spicy chili flavor
- Tomato flavor
- Sour cream and onion flavor
- Sweet corn flavor
Manufacturers can develop different formulations to meet consumer preferences in different markets.
Uniform seasoning is essential because uneven coating can result in inconsistent taste from one snack to another.
Step 8: Cooling
After seasoning, the products need to cool before packaging.
A cooling conveyor allows air to circulate around the snacks and remove residual heat.
This stage is particularly important because packaging hot products may cause condensation inside the bags.
Excess moisture can reduce crispness and negatively affect product shelf life.
Therefore, manufacturers should ensure that the snacks have reached a suitable packaging temperature before proceeding.
Step 9: Weighing and Packaging
The cooled products are transferred to an automatic weighing and packaging machine.
Depending on market requirements, manufacturers can choose different packaging formats, such as:
- Small individual snack bags
- Medium-sized retail packages
- Large family-size bags
- Multipack snack packages
Packaging materials should provide suitable moisture and oxygen barriers to help preserve the product’s crispness, flavor, and freshness.
Automatic packaging equipment can improve weighing accuracy, reduce labor requirements, and increase production efficiency.
