Potato starch processing line adopts the wet processing technology of starch production, and no additives are added in the whole production process. As a professional potato starch processing machine manufacturer, the whole potato starch processing line has the features with matured technology, advanced equipment, scientific configuration and reasonable technology.

Potato starch processing machine

The potato starch processing machine used for potato starch production includes:
1.Potato cleaning and washing machine
After being weighted and sorted, the fresh potato will be firstly transported into the potato starch processing machine to clean the sand, small stones, dirt and other impurities. Then the cleaned potato will be transported into the washing machine. To achieve a better cleaning effect,  it will be better to use the rotary washing machine, so that the impurities such as sand, stone, iron items will be thoroughly cleaned.

2.Potato rasping machine
After cleaning and washing in the potato starch manufacturing process, the potato will be crushed. Through the screw feeder, the potato goes into the rasper-an efficient potato starch processing machine for rasping and being crushed into potato slurry. Due to the rasping efficiency (the percentage of free starch available) is critical to the overall system rate, a special design has been made for the rasper to achieve the highest possible photo rasping efficiency.

3 Fiber separation machine
This potato starch processing machine is for separating fiber from starch in potato starch processing plant. Potato starch slurry is pump into the first level centrifuge sieve, the wet fiber comes down from the first screen is then pumped into the second, third and the fourth extraction screen, thus to achieve better separation effect. And fine fiber sieve is also used in potato starch processing plant for separating fine fibers and starch.

 
4 Starch slurry desanding machine
Starch milk after separation is sent to a mixing tank of potato starch processing machine. Then we can use two levels of desander to expel sand out of starch slurry, and the sand collected uses butterfly valve to eject.

5.Concentrating and refining machine
After separating, the starch milk goes into next potato starch processing machine for concentrating and refining to further separating the protein and cell sap.In this section, the starch milk is firstly concerntrated through the hydrocyclone station, while the overflow of cell sap goes into recycling hydrocyclone station to recycle the containing starch.After multi-stage washing it not only ensures the washing effect of the starch but also avoids the loss of starch in the cell sap.

6.Starch mlik dewatering machine
The water content of starch milk coming out of hydrocyclone station is too high to dry directly. Therefore, it is necessary to dehydrate starch milk first to reduce water content of starch. The potato starch processing machine for dewatering is the vacuum filter. Vacuum pump makes vacuum negative pressure inside the vacuum drum. When starch milk contacts vacuum drum, starch milk is sucked on the surface, while the filtrate is sucked into the filtrate separation and filtrate pump away. The filter cake is scraped off by the scraper, then is conveyed into feed hopper of flash drier.

Potato starch drying machine

7 Starch drying and packing machine
The potato starch processing machine for drying process is flash dryer. The starch after drying uses high efficiency cyclone to collect, and finished products of drying machine use pneumatic conveyor or screw conveyor to cool. Then the cooling dry starch is sent to the sieving machine by two stage cyclone separator collection and screw conveyor. After screening, the starch is packed by semi-automatic packing machine for warehousing. And then the whole processes for potato starch processing plant are completed.
