How Are Potato Chips Manufactured?

Potato chips are a very popular snack, made from fresh potatoes through a series of processing steps. So How are potato chips manufactured? The manufacturing of potato chips mainly includes washing, peeling, slicing, blanching, and frying. Each step is important in the potato chips manufacturing, but the manufacturing steps will vary depending on the production scale and product requirements. Below, we will introduce the main manufacturing steps.

The first step is washing and peeling. Fresh potatoes are fed into a washing machine, where brushes and spray water remove surface dirt and impurities, while also peeling the potatoes to prepare them for subsequent processing.

Next comes slicing. The peeled potatoes are sliced into even, thin slices using a slicer. The thickness of the slices can be adjusted according to product requirements, ensuring a smooth cut.

Blanching is the next crucial step. Blanching the sliced potatoes in hot water removes excess starch, prevents oxidation and discoloration, and makes the chips crispier when fried.

Next, the potato chips are deep-fried. After blanching, the potato chips are placed in a deep fryer and quickly fried in hot oil until they turn golden brown and crispy. The frying temperature and time must be strictly controlled to ensure that each chip has a uniform color and consistent taste.

After frying, the potato chips undergo deoiling, seasoning, and packaging. Excess oil is removed by a deoiling machine, then seasoning powder is added according to different flavors, and finally, they are sealed in automatic packaging machines for market sale.

The level of automation and equipment configuration in the potato chips manufacturing will vary depending on the production scale and product requirements. For example, small factories may use semi-automated equipment, while large factories use fully automated potato chips production lines to achieve continuous production.
