If you’re planning to launch a medium-scale potato chips production business, understanding the full chips processing line is your first step toward success. A typical line with a capacity of 300–500 kg/h involves a series of integrated machines that transform fresh potatoes into crispy, high-quality chips. This article provides a detailed, step-by-step guide to how a complete potato chips production line works and highlights the key equipment required.
1. Potato Sorting and Washing
The process starts with raw potato sorting, washing, and peeling. Fresh potatoes are fed into an elevator that delivers them to a combined washer and peeler machine. This step ensures all skins and impurities are removed, preparing clean raw materials for slicing.
→ Machines used: Screw feeder, potato washer & peeler, selection conveyor
2. Slicing
Washed and peeled potatoes are transferred to a potato slicer. Uniform slicing is essential for consistent frying results and product quality. By using interchangeable blades, you can produce straight-cut chips or ripple-style variations.
→ Machines used: Potato slicer, conveyor belt
3. Rinsing and Blanching
The potato slices go through a rinsing system to remove surface starch. After rinsing, the slices enter a blanching machine, where they are briefly cooked. This step prevents enzymatic browning, improves chip texture, and extends shelf life.
→ Machines used: Washing flume, blanching machine
4. Dehydration before Frying
A dehydator by air blowing is used to remove excess water from the slices. Proper dehydration reduces oil absorption during frying and helps achieve a light, crispy texture.
→ Machine used: Dewatering machine
5. Frying
This is the core step of the chips production line. The slices are fried in hot oil using a continuous fryer equipped with automatic temperature control and oil filtration systems. This ensures uniform cooking and maintains oil quality over time.
→ Machine used: Continuous fryer
6. De-oiling and Seasoning
After frying, the chips pass through a de-oiling system to remove excess surface oil. Then, they are transferred to a rotary seasoning drum where flavorings—either powder or liquid—are evenly applied.
→ Machines used: Oil removing machine, seasoning drum
7. Cooling
Before packaging, the chips need to cool down to room temperature. An air cooling conveyor is used to avoid moisture condensation inside packaging bags, which can affect product quality.
→ Machine used: Air cooling machine
8. Packaging
Finally, the chips are automatically weighed, portioned, and packed. A multi-head weigher ensures precision, while a vertical form-fill-seal (VFFS) machine creates sealed bags. Optional nitrogen flushing keeps the chips crisp and fresh for longer shelf life.
→ Machines used: Multi-head weighing machine, VFFS packing machine
Why Choose a Medium-Scale Potato Chips Production Line?
A 300–500 kg/h production line strikes the perfect balance between output, automation, and investment. It’s ideal for local snack factories, food startups, or contract manufacturers looking to scale efficiently. With the right setup, you can produce potato chips that meet or exceed national brand standards.
Final Thoughts
Investing in a medium-scale potato chips making machine setup means more than just buying equipment—it requires understanding the complete workflow. From peeling to packaging, each step plays a critical role in final product quality. By choosing reliable machinery and a well-planned layout, your chips production line can become a high-performing and profitable operation.
