The Working Process Of The Sweet Potato Starch Production Line
First, the basic principles of cleaning
The role of cleaning: the main is to remove the outer surface of sweet potatoes dip with the sediment, and wash away the roots of sweet potato roots. As the raw material for the production of starch - fresh sweet potato or sweet potato chips for cleaning, is to ensure the basis of starch quality, cleaning the more clean, the better the quality of starch.
Second, the basic principles of broken solution
The role of broken solution: sweet potato starch is mainly stored in the fleshy part of the root, only a small amount stored in the endothelium. The purpose of broken solution is to destroy the sweet potato's organizational structure, so that tiny starch particles can be successfully separated from the root of the disintegration of the separation. The starch released from the cells, called free starch; remains in the internal cells of the dregs called bound starch.
Third, the basic principles of screening
Sweet potato residue is slender fiber, the volume is greater than the starch particles, Peng rose coefficient is greater than the starch particles, the proportion of light and more than starch particles, the broken pulp, water as the medium, so that the potato residue containing starch slurry further Filter out.
Fourth, the basic principles of purification and precipitation
The proportion of mud and sand is greater than that of water, and it is greater than the proportion of starch granules. According to the principle of separation of gravity, the use of cyclone sand removal, or the sedimentation method using the trough, can achieve the desired effect. And the proportion of yellow pulp, close to the water, and the proportion of starch particles lighter, the shape of the palm shape, the longer the processing cycle, the greater the performance of adhesive, sticky sieve, sticking starch particles, extremely difficult to separate, it requires fresh raw materials, Short process, timely separation
Fifth, the basic principles of dehydration
The concentrated starch slurry still contains more water, and further dehydration can be dried.
Six, the basic principles of drying
Starch plant generally used in the air drying (also known as rapid drying) the entire process time is completed in a flash, so the starch particles within the water too late gelatinization has been dry, it will not happen gelatinization or degradation phenomenon.
