Sweet Potato Starch Production Line

Sweet potatoes, also known as potatoes, are our company's leading products in the production of sweet potato starch equipment. The sweet potato starch processing equipment includes a purification cyclone production line, an airflow collision drying equipment with a low-temperature low tower, and a complete production line with a daily output of 5-100 tons of starch and refined starch. We currently have a complete set of production and manufacturing equipment for testing (all large conversion equipment undergoes dynamic balance tests, starch complete sets of equipment, and our company is continuously trial producing complete sets of production equipment).

Main equipment and process flow for sweet potato starch processing:

Sweet potatoes → (cleaning conveyor) → cleaning (cleaning cage) → crushing (hammer mill or file mill) → slurry separation (pressure curve screen or centrifugal screen, slurry separation circular screen) → desanding (desander) → protein fiber separation (disc separator, concentration and purification cyclone unit) → dehydration (centrifuge or vacuum dehydrator) → drying (low-temperature low tower airflow collision starch dryer) → packaging and storage. If the entire production process adopts the automated starch processing production line of Kaifeng Sida Company, it only takes 30 minutes from fresh potatoes of agricultural products to packaging and storage of starch products, which is of high quality, efficient, energy-saving and labor-saving.

Introduction to the main equipment of sweet potato starch processing production line

1. Cleaning and conveying feeding: For small ones, use secondary cleaning and conveying. For larger scales, three-level cleaning is used. In order to clean the raw materials thoroughly, a cleaning cage or a stone removal machine must be used to remove impurities such as sediment, stones, and iron objects. This can also achieve the goal of saving manpower and water resources.

2. Crushing: Fresh potatoes are crushed once using a file grinder or hammer crusher. The crushed particles are moderate, the starch particles are large, the quality is good, and the yield is high or low. Different specifications of equipment can be selected according to needs. It is a hammer crusher with good durability, low damage, and easy maintenance.

3. Desanding: Nowadays, a considerable number of small factories have developed from manual workshop production. Starch has a high sand content and poor taste, which affects the sales volume and price of starch, and dampens the productivity of producers. Using our desander for desanding can remove sand from starch at once, improving product quality. This equipment is easy to use and has obvious effects, which can reduce the sand content of starch to below 0.3%, while the desanding process is continuous.

4. Slurry separation: Slurry separation is an important step in starch production, and this process and crushing process determine the yield of starch. Our factory puts ourselves in the shoes of the receiving party and has designed and produced a series of slurry separation equipment from small to large. In terms of small size, due to various objective conditions such as site and economic conditions, as well as production scale, it is necessary to produce more while saving costs and ensuring clean separation of pulp and slag. Therefore, a horizontal extended horizontal screen is both economical and practical. Even medium-sized manufacturers have been using centrifugal screens (with a speed of 1800-2000 revolutions per minute), which use the centrifugal force generated by high-speed rotation to separate pulp and slag. Large scale manufacturers have further improved the separation effect of slurry and slag by using stainless steel pressure curved screens and vertical centrifugal screens.

5. Protein separation: In the processing of sweet potato starch, the proteins contained in sweet potatoes must be separated, and this separation process is called purification in the processing technology. The equipment used is also known as purification equipment. It includes a butterfly separator and a cyclone separator, which are used to separate protein from starch slurry. The dry matter is commonly known as yellow powder. The content of yellow flour in starch is not strictly required in the food industry, while in industrial grade starch, the requirements for modified starch are quite strict. Therefore, in order to produce high-quality starch, purification equipment must be used as a guarantee.
6. Dehydration: There are three types of dehydration: three legged centrifuge, automatic scraper centrifuge, and vacuum filter. Among them, the vacuum filter has excellent performance. It not only works smoothly (3-5 revolutions per minute), but also saves energy and has a good dehydration effect at 35% moisture.

7. Drying: Our company's starch drying equipment is a low-temperature low tower airflow collision starch dryer, which is popular both domestically and internationally. Its characteristics include easy installation, centralized heating, large heat supply, significant energy-saving effect, and low-temperature drying of starch at 50 degrees Celsius. The dried starch is further processed into vermicelli, effectively maintaining the high quality of the product.
