Potato Starch manufacturing process technology

Kaifeng sida tapioca starch processing machinery manufacturer supplies tapioca starch processing machinery, installs tapioca starch processing plants and provides complete sets of tapioca starch equipment.

Technical Process of Potato Starch Production:

Cleaning and Washing Potato Starch (tapioca) Roots

Wash the fresh Potato Starch (tapioca) 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 starch(tapioca).

Cleaning and Washing Potato Starch (tapioca) Roots

Peeling Potato Starch (tapioca) Roots

Peel the washed Potato Starch (tapioca) roots to remove the outer brown skin and inner thick cream layer. The water source should be checked regularly to ensure it is not dirty or contaminated

Crushing Peeled Potato Starch (tapioca) Roots into Slurry

Crushing the peeled Potato Starch (tapioca) roots into the slurry and separate to remove the coarse Potato Starch residues to obtain uniformly smooth Potato Starch slurry. The crushing drum and all food contact areas should be made from stainless steel.

Potato Starch (tapioca) Slurry and Residues Separation

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

Starch Refining and Concentrating

Pure Starch Milk De-wateringDe-watering the pure starch milk to 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(tapioca) with low moisture content by the principle of heat transfer exchange. The drying process is more reliable and of higher quality.
