Similar Sweet potato starch processing line
sweet potato starch processing line with mature technology, advanced equipment, reasonable design. The whole set machine used in sweet potato starch processing line includes: feeding machine, dry sieve, rotary washing machine, rasper, centrifuge sieve and fine fiber sieve, desander, hydrocyclone station, vacuum filter dewatering, flash dryer, sieving machine, packaging machine.
The production process in sweet potato starch processing line is as below:
1.Cleaning: Using dry sieve to remove the outer peelers, attached sand, leaves and other debris. This is the first step to ensure high quality starch.
2.Washing: Rotary type washing machine is adopted to wash sweet potato which has the features of large capacity, high efficient and good washing effect. In sweet potato starch processing line, the cleaning and washing are the basics for further processing.
3.Grating: Then it comes to the most important procedure in the whole sweet potato starch processing line. Grating serves to grate sweet potato into mesh to extract free starch out of cell. The more starch extracted, the higher starch yield.
.Starch and residue separation: To remove fibers out of starch slurry. Multistage centrifuge sieve is adopted in sida sweet potato starch processing line for better separation effect.
5.Sand removal: The sand in starch slurry not only effect the taste of starch, but also reduce the fineness of starch, therefore it is required to be discharged in sweet potato starch processing line by desander.
6.Hydrocyclone refining: To use 18 stage hydrocyclone station in series to achieve the concentration, refining, washing and recovering of starch slurry in sweet potato starch processing line.
7. Vacuum filter dewatering: The main purpose of this step is to reduce the water content to the required quality for drying. The moisture content after dewatering is about 38%-40% in sweet potato starch processing line.
