Processing technology of complete set of sweet potato starch equipment

One, the basic principle of cleaning the role of cleaning: mainly remove the outer layer of sweet potato with sediment, and wash the 

root of the sweet potato cuticles.The fresh sweet potato as raw materials for the production of starch ─ or sweet potatoes dry cleaning, 

is the basis of guarantee the quality of starch, the net clean, starch quality is better.

2. Basic principles of shredding the role of shredding: sweet potato starch is mainly stored in the fleshy part of root tubers, and only a 

small amount is stored in the endothelium.The purpose of crushing is to destroy the tissue structure of sweet potato, so that the small 

starch granules can be successfully separated from the root tuber.The starch released from the cell is called free starch.The cells 

remaining in the dregs are called agglutinated starch.

Grinding is one of the most important processes in the processing of fresh potato, which is related to the yield of fresh potato and the 

quality of starch. The requirements for grinding are as follows:

The basic principle of sieving sweet potato residue is a slender fiber, the volume is larger than the starch granules, peng swelling 

coefficient is also larger than the starch granules, the specific gravity is lighter than the starch granules, will break the original pulp, with 

water as the medium, so that the starch pulp water contained in the potato residue is further filtered out.

The proportion of mud and sand is greater than that of water and the proportion of starch granules. According to the principle of 

specific gravity separation, the use of swirling sand removal, or the use of flow tank sedimentation method, can achieve more ideal 

results.The specific gravity of yellow pulp is close to water and lighter than the specific gravity of starch granules. Its shape is palm 

shape. The longer the processing cycle, the greater the adhesive performance.

Basic principles of dehydration concentrated starch pulp still contains more water, further dehydration before drying.

At present, generally used in the starch plant airflow drying (also known as flash drying) the whole process time is completed in a flash, 

so the water inside the starch particles to gelatinization has been dry, gelatinization or degradation will not occur.Airflow drying is a 

concurrent process, that is, the concurrent process of wet powder material and hot gas flow, which is composed of two processes of 

heat transfer and mass transfer.When the wet starch is in contact with the hot air, the hot air will transfer the heat energy to the surface 

of the wet starch, and then from the surface to the internal, this process is the heat transfer process;At the same time, the moisture in 

the wet starch diffuses from the material to the surface of the starch in the form of liquid or gas, and then diffuses from the surface of 

the starch to the hot air through the gas film, which is a process of mass transfer.It is to balance heat exchange between high-

temperature airflow and wet starch in the drying tube, so that the dry starch is in powder form and can be packed into the storage after 

cooling.
