Sweet potato starch machine

The sweet potato starch machine used for extraction of starch from sweet potato procedure:
Fresh potato (conveyor machine)- cleaning (dry sieve)- washing(rotary washing machine)- grinding (rasper)- starch and slag separation (centrifugal sieve, fine fiber sieve)- desanding (desander)- protein separation (hydrocyclone station)- dehydration (vacuum filter)- drying (flash dryer)-packing(semi-automatic packing machine)

Raw material transportation, cleaning and washing machine
The fresh sweet potato roots piled up in the stockyard in sweet potato starch processing plant is collected through the ground, and transported by a belt conveyor to the cleaning and washing machine. In sweet potato starch preparation process, the stone, weed, sand and other debris therein are initially removed by the collision and friction of the cleaning machine. Then the sweet potato enters the washing unit. After the cleaning and washing process by sweet potato starch machine, the mixed sand and other debris on the surface of the sweet potato roots have been basically removed, and the washed sweet potato enters the grinding unit.

Rasper for sweet potato crushing machine
Rasper is an important sweet potato starch machine in sweet potato starch preparation process which determine the starch yield. Therefore the sweet potato starch processing machinery manufacturer introduce the international advanced technology to design and manufacture this machine. DOING rasper is such an achievement based on advanced EU technology and extraction rate up to 95%.

Starch slurry separating machine
For how to remove starch from sweet potatoes, the purpose of this sweet potato starch machine is to separate fiber out of starch slurry. Centrifuge sieve and fine fiber sieve are separately used for removing fiber and fine fibers.

Sand removal machine
Desander cyclone is a sweet potato starch machine used for removing sand content in starch slurry so as to improve the taste of sweet potato starch. it has such advantages as small ground occupation, less investment, easy installation, handy maintenance and high desanding effect.

Starch concentration and refining machine
Hydrocyclone station is a sweet potato starch machine to concentrate and refine and recycle starch. To achieve multiple functions such as concentration, recovery, washing and protein separation, sweet potato starch processing machinery manufacturer usually design multi-stage cyclone for sweet potato starch manufacturing process.

Starch milk dewatering machine
It is a sweet potato starch machine used for decrease moisture content of starch to meet the requirement of subsequent drying process. A more elaborate type siphon peeler centrifuge is equipped with a backwashing device (optional) to flush the outside of the centrifuge drum and the inside of the casing to achieve process cleanliness requirements.

Sweet potato starch drying machine
After dewatering, the water content in starch is still high so it need to be dried in sweet potato starch processing plant. The sweet potato starch machine used in this process is flash dryer. The flash dryer adopts the negative pressure drying system which can effectively reduces the loss of the starch and meanwhile purifies the working environment. The high speed hot air dry the starch just in 2-3 seconds which has an significant energy saving effect.

Industrial sweet potato starch machine for sweet potato starch preparation

The process route of the sweet potato starch processing technology adopts the wet processing process of sweet potato starch, which including sweet potato starch machine for raw material cleaning, washing, cutting and crushing, starch slurry separating,concentration and refining, starch dewatering, the negative pressure air flow drying and packing.

Sweet potato starch machine 

1. Cleaning and washing machine: The cleanness of the material have an vital influence on the end products, therefore the cleaning and washing section are important in hot sale sweet potato roduction line. In this section the attached sand, dirt, weed, soil and other debris of sweet potato are first cleaned in sweet potato starch machine. The dry sieve is designed with inner spiral which can push forward sweet potato during the cleaning process. There is no water needed for this machine. Then the cleaned sweet potato enters into sweet potato washing machine for further wash the outer impurities.

2.Cutting and crushing machine: Due to the big size of sweet potato, it will be better to cut it into small piece before crushing process. The cutting machine is used for this purpose. After cutting, the sweet potato is transported into rasper for crushing by screw feeder. As an important sweet potato starch machine, rasper is mainly used for destroying the tissue structure of sweet potatoes so that the small starch particles can be separated from the roots.

3. Separating machine: The crushed sweet potato paste contains other impurities like fiber, protein and cell sap. Therefore the separating process is needed. It also has an important influence on the starch yield. In sweet potato starch production line, centrifuge sieve is widely used sweet potato starch machine for separating fiber out of starch.

4. Desanding machine: According to the principle of specific gravity separation, the starch slurry is pumped into the desander by a pressure pump, and the bottom stream is desanded by this sweet potato starch machine, and the top stream is passed through the slurry to achieve the purpose of sand removal.

5. Concentration and refining machine: Instead of traditional precipitation process, the concentration and refining process can separate non-starch substances with high efficiency, thus to improve the quality and whiteness of sweet potato starch. And hydrocyclone station is the widely used sweet potato starch machine in sweet potato starch production line for this purpose. Hydrocyclone station can effectively separate non-starch substances such as protein, fiber and cell sap in starch.

6. Dehydration machine: The water content of starch milk coming out of hydrocyclone station is too large to dry directly. Therefore, it is necessary to dehydrate starch milk by sweet potato starch machine first, so that the water content of starch is about 38%-40%.

7. Drying and packing machine: After dewatering, the wet starch is transported to the flash dryer for drying. The flash dryer takes use of the negative press principle to dry the wet starch which can effectively control the loss of the starch.  And the last sweet potato starch machine is semi-automatic packaging machine. It can save labors for the factory.
