Sweet potato starch machine
Raw material transportation, cleaning and washing machine
The fresh sweet potato roots piled up in the stockyard in sweet potato starch processing plant is collected through the ground, and transported by a belt conveyor to the cleaning and washing machine. In sweet potato starch preparation process, the stone, weed, sand and other debris therein are initially removed by the collision and friction of the cleaning machine. Then the sweet potato enters the washing unit. After the cleaning and washing process by sweet potato starch machine, the mixed sand and other debris on the surface of the sweet potato roots have been basically removed, and the washed sweet potato enters the grinding unit.
Rasper for sweet potato crushing machine
Rasper is an important sweet potato starch machine in sweet potato starch preparation process which determine the starch yield. Therefore the sweet potato starch processing machinery manufacturer introduce the international advanced technology to design and manufacture this machine. DOING rasper is such an achievement based on advanced EU technology and extraction rate up to 95%.
Starch slurry separating machine
For how to remove starch from sweet potatoes, the purpose of this sweet potato starch machine is to separate fiber out of starch slurry. Centrifuge sieve and fine fiber sieve are separately used for removing fiber and fine fibers.

Sand removal machine
Desander cyclone is a sweet potato starch machine used for removing sand content in starch slurry so as to improve the taste of sweet potato starch. it has such advantages as small ground occupation, less investment, easy installation, handy maintenance and high desanding effect.
Starch concentration and refining machine
Hydrocyclone station is a sweet potato starch machine to concentrate and refine and recycle starch. To achieve multiple functions such as concentration, recovery, washing and protein separation, sweet potato starch processing machinery manufacturer usually design multi-stage cyclone for sweet potato starch manufacturing process.
Starch milk dewatering machine
It is a sweet potato starch machine used for decrease moisture content of starch to meet the requirement of subsequent drying process. A more elaborate type siphon peeler centrifuge is equipped with a backwashing device (optional) to flush the outside of the centrifuge drum and the inside of the casing to achieve process cleanliness requirements.
Sweet potato starch drying machine
Sweet potato starch drying machine
After dewatering, the water content in starch is still high so it need to be dried in sweet potato starch processing plant. The sweet potato starch machine used in this process is flash dryer. The flash dryer adopts the negative pressure drying system which can effectively reduces the loss of the starch and meanwhile purifies the working environment. The high speed hot air dry the starch just in 2-3 seconds which has an significant energy saving effect.
