The extraction of starch from potato procedure in Henan Doing Company adopts the wet processing technology of starch production which contains no additive. The whole process has the features of high degree of automation, mature technology, advanced equipment and scientific configuration. The process flow of extraction of starch from potato procedure includes: potato cleaning process, washing process, grating process, separating process, concentration and refining process, dehydration process and drying process.

Extraction of starch from potato procedure


Preprocessing of potato
a.The first process is cleaning. Dry sieve is a widely used cassava cleaning equipment whose main function is to remove the sand, soil, weed and other impurities from cassava for extraction of starch from potato procedure. This equipment adopts multiple inner spirals design which achieve the transportation function during cleaning process. It can not only play the function of quantitative conveyance, but also control the size of material conveyance.

b.Then the cleaned cassava is transported into washing equipment. Rotary washing equipment is a widely used potato washing equipment in extraction of starch from potato procedure. It adopts countercurrent washing principle which has a better washing effect. On the one hand, fresh potato in the rotary washing equipment moves in a circular motion along the drum wall, and on the other hand, moves in a straight line along the axis. In this way, fresh potatoes are well washed.  Reasonable feeding ensures low breakage rate of raw material and high starch extraction rate. The breakage rate is lower than 1%.

2.Potato starch extraction and purification process:
a. The washed potato is then transported into rasper for grating. Rasper is used for grating potato to break the cell wall of potato and release starch from potato cell. This is an important procedure in extraction of starch from potato procedure. DOING rasper is a potato starch processing machine widely absorbs advanced international technology. Compared with other products, it is composed of hundreds of saw blades, and featured with high speed, fine grinding, high free rate of starch, high production capacity and high rate of starch extraction.

b. The grated potato slurry need to be further processed to remove the impurities from starch. Centrifuge sieve is used to separating fiber and potato starch in extraction of starch from potato procedure. Multiple screening or countercurrent washing processes are generally adopted. It is required that after the separating and washing process, and the starch content of the residue should less than 35%. And fine fiber sieve is also used to further remove the small fiber so as to improve the fineness and quality of potato starch.

c. Then is the concentration and refining process in extraction of starch from potato procedure. Hydrocyclone station is widely used for this process. The hydrocyclone station is composed of multistage cyclone in a certain way. According to the processing function of each stage cyclone in the cyclone station, different number of cyclone pipes and a feed pump need to be installed.

3.Potato starch dehydrating and drying:
a. After that, the potato starch need to be dehydrated. Vacuum filer is the main equipment for this process in extraction of starch from potato procedure. It take use of negative pressure principle. When working, the starch is adsorbed on the filter cloth of the drum and is scraped off by the fixed scraper. While the filtrate enters the separator, so as to achieve the purpose of separation of starch and water.

b. The final process in extraction of starch from potato procedure is drying process. This is mainly used to dry the wet starch to meet the production standards. Flash dryer as the drying equipment has the features of high thermal efficiency, short drying time and large handling capacity. Drying process requires the particle size of the potato starch in the range of 0.5mm and 0.7mm.
