The cereal corn flakes production line is an industrialized and automated food production equipment system that processes corn (or mixed grains) into crispy, ready to eat breakfast corn flakes. The cereal corn flakes production line converts raw materials into standardized, crispy and flaky flaky food through continuous physical and thermal processing processes. The entire process is highly integrated and can achieve large-scale production.
1.Core production process of cereal corn flakes production line (6 major sections)
1. Raw material pretreatment and batching
Raw materials: corn flour/corn residue, sugar, salt, malt, vitamins, minerals, etc.
Equipment: raw material warehouse, screening and impurity removal machine, automatic measuring scale, premix machine, liquid addition system.
Function: Remove impurities, mix accurately according to the formula, and form a uniform mixture.
2. Steaming/extrusion conditioning (core)
Traditional process: High pressure steaming to completely gelatinize starch.
Modern technology: Double screw extruder (mainstream), high-temperature and high-pressure (120-145 ℃, 1.8-2.5MPa) instant gelatinization and puffing.
Effect: The material becomes flexible and porous, laying the foundation for tablet pressing.
3. Compression molding
Equipment: Heavy duty roller press.
Parameters: Press to 0.4-0.9mm ultra-thin uniform sheet, with a thickness error of ≤ 0.1mm.
Subsequent: Cut into square, circular, corrugated pieces, etc.
4. High temperature baking (key)
Equipment: Multi layer belt hot air oven.
Condition: 260-320 ℃, 2-5 minutes.
Function:
Rapid dehydration (moisture content reduced to 2-3%)
Puffing to form a crispy porous structure
Maillard reaction: golden, burnt aroma
5. Cooling and seasoning
Cooling: Air cooled to room temperature for stable texture and moisture resistance.
to flavor:
Spray coating: oil, syrup, flavor liquid
Sprinkle powder: sugar powder, cheese powder, spices
Secondary drying: fix seasoning.
6. Packaging and Testing
Equipment: metal detector, weight inspection scale, automatic pillow/vertical packaging machine.
Function: Sealing and oxidation prevention, nitrogen filling and preservation, automatic metering, and finished product traceability.
2.Types and capacity of cereal corn flakes production lines
Traditional steaming and cooking type: The taste is closer to the original, the cycle is long, and the efficiency is low.
Double screw extrusion type (mainstream):
High efficiency: The entire process takes about 30 minutes
Capacity: Small 180-250kg/h; Medium size 300-500kg/h; Large scale ≥ 1000kg/h
Flexible: capable of producing corn flakes, oatmeal, wheat balls, miscellaneous grains, etc
3.Technical characteristics of cereal corn flakes production line
Automation: PLC central control, precise and stable parameters (temperature, speed, thickness).
High quality: The thickness, moisture content, color, and brittleness are highly consistent.
Nutritional enhancement: Vitamins, minerals, and dietary fiber can be added online.
Energy saving: waste heat recovery, hot air circulation.
4.Application products of cereal corn flakes production line
Original flavor corn flakes, honey corn flakes, chocolate corn flakes, cheese corn flakes, mixed grains, ready to eat breakfast cereals.
Simply put, the cereal corn flakes production line is a fully automated factory assembly line that turns corn into crispy, ready to eat, standardized corn flakes, and is the core equipment of modern breakfast cereal industry.
