| Starch dewater machine in potato starch plant |
Potato starch production is an isolation of potato starch from fresh potato. It takes place in potato starch plant. Starch industry is a part of food processing which is using starch as a starting material for production of starch derivatives, hydrolysates, dextrins.
The potato starch extraction process comprises the steps such as delivery and unloading potatoes, cleaning, rasping of tubers, potato juice separation, starch extraction, starch milk rafination, de-watering of refined starch milk and starch drying.
1. Delivery and unloading potatoes in potato starch plant
Fresh potatoes are delivered to the starch plants via road or rail transport. Unloading of potatoes could be done in two ways:
2. Cleaning and washing potato in potato starch plant
Coarsely cleaning of potatoes takes place during the transport of potatoes to the scrubber by channel.
3. Rasping of potatoes in potato starch plant
Most often the rasping of potato tubers is carried out with a rotary grater. The purpose of this stage is disruption of cell walls, which therefore release the starch.
4. Potato starch extraction-potato fiber separation in potato starch plant
This allows the recovery full-value protein from juice and reduces the onerousness of water juice as a sludge.
5. De-sanding process in potato starch plant
This process is remove the small amount sand in the starch slurry to increase the quality of final potato starch .
6. Starch milk purification and concentration in potato starch plant
Normally we use the hydro cyclone groups to do starch purification and concentration
7. Potato starch de-watering and drying in potato starch plant
It is a suspension of starch in water, which needs de-watering up to 38% of moisture to get the wet starch . Then use hot air flash dryer to dry starch to 18~20% of moisture to get the final product potato starch for sale .
