Potato Starch Process Description and Flowchart:

Goodway has been continuously developing potato starch making machine since 1991 to maximize product quality. From potato root hopper until the packaging stage, we can supply machines together with production process know-how.

The production process of potato starch comprises the steps such as delivery and unloading potato, washing, crushing slurry and residues separation, desanding & desilting, starch concentrating and refining, de-watering, starch drying, and packaging. We provide below a brief description of the main steps of the potato starch production process.

Note: Goodway updates the potato starch machine and potato starch processing production line technology and machinery based on the latest experience. This starch manufacturing machinery also can be used as cassava starch making machine.

Cleaning and Washing Potato Roots

Wash the fresh potato roots in clean water to remove the surface mud and sand. It's the first step of potato starch process and very important for the quality of final potato starch.

Crushing Washed Potato Roots into Slurry

Crushing the washed potato roots into the slurry and separate to remove the coarse potato residues to obtain uniformly smooth potato slurry. The crushing drum and all food contact areas should be made from stainless steel.

Potato Slurry and Residues Separation

The commonly physical operation to separate fine potato residues from potato slurry. Oversize particles of potato residues cannot pass through the lattice structure of the filter, while fluid and small particles of potato slurry can pass through to become filtrate.

Raw Starch Milk Desanding and Desilting

Solid control equipment that separates tiny sand and mud from the raw starch milk. Desander is installed before the desilter and normally the solids diameter for desander to be separated would be larger than for desilter.
