The potato starch making process 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 potato starch production includes: potato cleaning, washing, grating, separating, concentration and refining, dewatering, drying and packing.
Potato starch processing plant
1. Pretreatment of raw material
b. Cleaning and washing: The purpose of cleaning and washing is to wash raw potato roots thorough multiple stage cleaning and washing process so as to fully wash the dirt, soil, sand and other skin sediment. Thus it can improve the purity of the raw material, and facilitate the next process of potato starch making process. And the widely used machine for this section is dry sieve and paddle washing machine. The main features of these machine are low water and power consumption, large capacity and easy handling.

b. Screening: The crushed starch slurry need to be screened to separate the starch milk from the fibers. At present, the centrifuge sieve is widely used for separating for potato starch making process. The two machines are used together, that is, the centrifuge sieve is firstly used to separate fiber from starch by high speed centrifugal force.
c. Concentration and refining: The starch milk from the first stage centrifugal screen enters the hydrocyclone station, and the process water is pumped from the other end of the cyclone station to wash the starch countercurrent. The hydrocyclone station for potato starch making process can be divided into three parts: the first starch milk goes to the concentration cyclone station for concentrating, then the concentrated starch milk goes into the backwashing unit, while the overflow of cell SAP enters into recycling cyclone station for recycling of contained starch. Thus the concentrating, washing and refining process of the potato starch are completed.

b. Drying and packing: This section is for quickly removing moisture from wet potato starch for potato starch making process. The equipped machine in this section is flash dryer which has the features of high drying strength, strong evaporation capacity, short drying time and good starch quality. Then the dried starch is packed by semi-automatic packing machine for sale.
