Is the food puffing production process complicated?
Sep 05, 2025| Puffed corn production line
Many people might think that since it's just a snack, how complex can the production technology behind it be? Actually, that's not the case. From a whole kernel of corn to the crispy, delicious triangle in our hands, it goes through a highly automated and rigorous production line.
1. Raw Material Handling and Mixing System
This is where all the work begins. The production line first processes the raw materials, primarily corn flour (or corn grits), water, cooking oil, and various seasoning powders.
2. Extrusion and Cutting Device
This is the hallmark of efficiency in the entire production line. The mixed dough is fed into an extruder. Under high temperature and pressure, the dough becomes soft and malleable, then forced through a specialized die.
3. Baking and Dehydration System
The cut, shaped raw dough is conveyed by a mesh conveyor into a long oven (or toaster) for baking.
4. Seasoning and Coating System
The plain corn chips emerging from the oven are naturally flavorless. The next important step is seasoning. The seasoning system typically consists of a large drum where the chips are tumbled at a constant speed.
5. Cooling and Packaging System
The product, freshly seasoned, is still relatively hot. If packaged directly, moisture will condense inside the packaging, causing the product to become damp and soft, losing its flavor. The product then passes through a cooling tunnel until it is ready for packaging.
| Model | Power | Capacity | Heater | Dimension(mm) | Weight |
| LXT-65 | 5.5kw | 50 kg/h | 1 kw | 1720*870*1050 | 350 kg |
| LXT-70 | 15kw | 150kg/h | 1 kw | 1720*970*1250 | 500 kg |
| LXT-85 | 18.5kw | 200-300kg/h | 2 kw | 1360*1870*850 | 650 kg |
| LXT-95 | 22kw | 400-500kg/h | 2 kw | 2300*1170*1400 | 850 kg |
Core facilities in the production line
Raw material mixer
The mixer is used to mix the powdered raw materials and liquid seasonings evenly. The moisture and starch content of the raw materials will directly affect the degree of puffing. Therefore, when selecting raw materials, it is best to choose raw materials with moderate moisture and starch content.
Snack Puffing Machine
Corn puffing machine is the most important machine in the production of puffed food. In the corn puffing cereal machine, the raw material is steamed and shaped at high temperature. Then it will be extruded through the holes of the die. Therefore, different puffed foods can be made by changing different shapes and molds.
Seasoning Machine
In order to obtain a unique taste, a seasoning machine is required for seasoning. The seasoning machine has the characteristics of continuous operation and will not destroy the structure of the puffed food.
Packaging Machine
For storage and transportation, expanded foods need to be packaged. We offer packaging machines that can produce both bag and box packaging formats.
