Features of Sweet Potato Starch Machine

Sweet Potato Starch Process Description and Flowchart:

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

The production process of sweet potato starch comprises the steps such as delivery and unloading sweet 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 sweet potato starch production process.

Note: Goodway updates the sweet potato starch machine and sweet potato starch processing production line technology and machinery based on the latest experience. Sweet potato washing machine and sweet potato starch packaging machine are also available.

Cleaning and Washing Sweet Potato Roots

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

Crushing Washed Sweet Potato Roots into Slurry

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

Sweet Potato Slurry and Residues Separation

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

Starch Refining and Concentrating

When raw starch milk enters the hydrocyclone, the pure starch milk of high density getting larger centrifugal force leaves from the underflow outlet, and the protein and other soluble impurities of low density getting smaller centrifugal force leave from the overflow outlet. Finally, achieve the purpose of various components of separation, and improve the quality of final starch with higher whiteness and purity.

Pure Starch Milk De-watering

De-watering the pure starch milk to the low water content of 35-40% by the principle of vacuum suction filtration. Ensure sufficient water has been removed, otherwise, the starch will form into lumps during drying.

Drying Wet Starch into Dried Starch

Effectively dry the wet starch into dried starch with low moisture content by the principle of heat transfer exchange. The drying process is more reliable and of higher quality.
