Detailed process of sweet potato starch processing

For the processing of sweet potato and other potato raw materials, the workflow usually includes multiple continuous and efficient sections. Through the close cooperation of advanced machinery and automation equipment, the whole process from raw material cleaning to finished starch packaging can be realized.

Detailed process of automated starch equipment:

1. Cleaning stage
Purpose: Remove impurities such as sand, soil, stones, weeds, etc. on the surface of sweet potatoes to ensure the pure quality and taste of starch, and also for the safety and continuous production of subsequent processing.
Equipment: Automated cleaning machine, different cleaning equipment configurations are carried out according to the soil content of sweet potato raw materials, which may include dry cleaning and wet cleaning combined equipment.

2. Crushing stage
Purpose: Crushing the cleaned sweet potatoes into crumbs or pulp to fully release starch particles.
Equipment: Sweet potato crusher, such as segmenter pre-crushing treatment, and then pulping treatment through a file grinder to form sweet potato slurry.

3. Slurry and residue separation stage
Purpose: Separate starch from impurities such as fiber in the crushed sweet potato slurry.
Equipment: pulp-residue separator (such as vertical centrifugal screen), through the high-speed rotation of the centrifugal screen basket, under the action of centrifugal force and gravity, the sweet potato pulp is screened to separate starch and fiber.

IV. Desanding and Purification Stage
Purpose: Further remove impurities such as fine sand in starch slurry to improve the purity of starch.
Equipment: Desander, through the principle of specific gravity separation, separate fine sand and other impurities in starch slurry.

V. Concentration and Refining Stage
Purpose: Remove non-starch substances such as protein and fine fibers in starch to improve the purity and precision of starch.
Equipment: Cyclone, through the concentration and refining action of the cyclone, separate non-starch substances in starch slurry to obtain pure sweet potato starch milk.

VI. Dehydration Stage
Purpose: Remove most of the water in starch milk to obtain wet starch.
Equipment: Vacuum dehydrator, using the negative vacuum principle to remove water from sweet potato starch to obtain wet starch with a water content of about 40%.

7. Drying stage
Purpose: Remove the residual water in the wet starch to obtain dry sweet potato starch.
Equipment: Airflow dryer, using the negative pressure drying principle to evenly dry the sweet potato starch in a short time to obtain dry starch.

8. Packaging stage
Purpose: Automatically package the sweet potato starch that meets the standards for easy storage and transportation.
Equipment: Automatic packaging machine, packaging according to the set weight or volume, and sealing.
