A corn starch production line is a complete set of equipment for processing fresh tuber products into starch. This line is suitable for common tuber crops such as sweet potatoes, potatoes, cassava, and kudzu. With changes to the conveying and washing equipment, it can also be used for ingredients such as bracken root, taro, lotus root, taro, and yams. Request a quote! WhatsApp/Phone: +86 13838385752.

Workflow of a Starch Production Line
The starch extraction process used in the potato production line has a clear flow. It mainly includes the following steps:
Fresh potatoes → Washing → Crushing → Filtration (coarse filtration) → Sand removal → Mud removal → Fine filtration → Sedimentation → Dehydration → Drying → Packaging
The raw materials undergo multi-stage washing and screening to remove impurities such as mud, sand, fiber, and protein. Then, through separation, concentration, and drying processes, the finished starch product is obtained.

Starch Production Line Equipment
Rotary Drum Screen
Function: The destoner is mainly used in the pre-processing stage. This equipment can effectively remove impurities such as stones and metals mixed in with the raw materials, reducing the risk of equipment wear and ensuring the smooth operation of the production line.

Starch Crusher
Function: The crusher grinds raw materials such as sweet potatoes and potatoes into a paste-like structure. Appropriate particle size helps improve starch formation rate.
| Model | Body Weight | Dimensions (mm) | Power (KW) | Remarks |
|---|---|---|---|---|
| FL – 520C | 160 KG | 1800 × 500 × 600 | 18.5–22 | 3–6 t/h |
| FL – 520B | 210 KG | 1800 × 620 × 600 | 22–30 | 5–8 t/h |
| FL – 520C | 250 KG | 2100 × 800 × 1200 | 30–55 | 10 t/h |
| Customizable |

Material Distribution Station
Function: The separation process is crucial in starch processing. The separator effectively separates starch from impurities such as fiber and protein through physical separation. It is an essential piece of equipment for ensuring high starch extraction rates.
| Model | Body Weight | Dimensions (mm) | Power (KW) | Remarks |
|---|---|---|---|---|
| FL – 450B | 150 KG | 2200 × 800 × 1100 | 4 | Combined Production |
Mud and Sand Removal Machine
Function: Used to further remove fine sand and muddy impurities from slurry, working in conjunction with a separator.
| Model | Body Weight | Dimensions (mm) | Power (KW) | Remarks |
|---|---|---|---|---|
| Sand Remover | 60 KG | 1200 × 500 × 2100 | 3 | Combined Production |

Fine Filter Machine
Function: Used in the starch microfiltration and coarse filtration stages, it can effectively remove protein and fine fiber impurities.
| Model | Body Weight | Dimensions (mm) | Power (KW) | Remarks |
|---|---|---|---|---|

| Fine Powder Sieve B | 320 KG | 5600 × 850 × 820 | 5.5 | Combined Production |
Starch Hydrocyclone
Function: Hydrocyclones operate based on the centrifugal principle. When a two-phase mixture enters the hydrocyclone tangentially from its periphery under a certain pressure, it creates intense three-dimensional rotating shear turbulence. Particle size differences cause centrifugal force, centripetal buoyancy, and fluid drag to act unevenly during operation. The equipment removes coarse particles through the underflow outlet and discharges fine particles via the overflow pipe, enabling stable separation and classification.

| Cyclone | – | Matched Set | Matched | Combined Production |
| Customizable | – | Customizable | Matched | Combined Production |

Starch Vacuum Dehydrator
Function: The vacuum dewatering machine uses the pressure difference created by the rotating drum and vacuum negative pressure to draw starch onto the surface of the filter cloth. The liquid passes through the filter cloth into the gas-liquid separator, where the starch on the drum surface gradually forms a filter cake. This cake is then removed by a scraper device, yielding solid starch with a low moisture content.
