Machines used for extraction of starch from sweet potato

  • Introduction

Sweet potato contains high starch. But it need take a series of steps to process sweet potato into starch. The machines used for extraction of starch from sweet potato includes sweet potato cleaning and washing machine, grinding machine, starch filtering and de-sanding machine, starch slurry concentration and purification machine, starch dewatering machine and starch drying and packing machine.

Machines used for extraction of starch from sweet potato

Here are the detail introduction of machines used for extraction of starch from sweet potato:

1. Sweet potato cleaning and washing machine: The machine used for sweet potato cleaning and washing process includes the dry sieve and rotary washing machine. These machines carry out multi-stage cleaning of raw materials (sweet potatoes), fully remove the skin sediment and improve the purity of raw materials. These machine features with continuous work without burden, multiple cleaning processes have high cleanliness and low energy consumption.

 

2. Sweet potato cutting and crushing machine: The machines used for extraction of starch from sweet potato in this section is: sweet potato cutting machine and rasper. The cutting machine is mainly for cutting the cleaned sweet potato into pieces so that it is easier to be grinded. The rasper is a high efficient grinding machine which is researched and designed by Doing Company on the basis of advanced international technology. The rasper features with high extraction rate with a free starch rate of 95%.

3. Starch slurry filtering and desanding machine: In this section the used machines used for extraction of starch from sweet potato includes: centrifuge sieve, fine fiber sieve and desander.

Centrifuge sieve and fine fiber sieve are mainly used for separation of fiber from starch. Multi-stage filtering process is carried out to improve the filtering effect. The desander machine is for removing sand out of starch slurry. According to the principle of specific gravity separation, the starch milk is pumped by pressure pump into the desander. The bottom flow is used to remove sand, and the top flow is used to discharge the slurry.

 

4. Starch slurry concentration and purification machine: The main machine of this section is starch cyclone station. The main function of this machine is high efficiency concentration and purification, separation of non-starch substances, improve the quality of starch whiteness. And the main features of this machine is easy operation, convenient maintenance and long service life.

5. Starch slurry dewatering and drying machine: The machines used for extraction of starch from sweet potato for these two section are vacuum filter and flash dryer. The refined starch has high water content, and the vacuum dewatering machine can effectively dewater of starch to reduce water content of starch so as to facilitate the next drying step. While the flash dryer is mainly for drying the dewatered starch so as to meet the commercial standard.

 

6. Packing machine and automatic control system: The sweet potato starch packing machines used for extraction of starch from sweet potato can be designed and manufactured according to customer's requirement. The automatic control system contains MCC operation cabinet, OCC control cabinet, LCB cabinet and CCTV monitoring system. This system mainly puts the industrial computer as the center to realize the visualized operation of central control room in the operation line.
