The starch processing technology is simple, the market demand is large, and the investment is small. It only needs to clean, crush, filter, sediment, and dry the cassava. It is a good project for cassava processing and suitable for family production. However, some places prohibit it because of environmental protection issues. Processing, if you have this intention, you need to consult the local government in advance. The market for noodles and noodles is large, the processing technology is simple, the investment is small, and the return is fast. It is especially suitable for family processing production. If you can process cassava starch yourself, the raw materials are guaranteed, the profits are higher, and the benefits are better.

1. Cassava potato cassava pueraria root cleaning stage
The cleaning is mainly to remove the mud and sand from the outer skin layer of cassava potato cassava root, and to remove the skin of cassava potato cassava root. The cleaning of cassava potato cassava root is important to ensure the quality of starch. The better, the more pure the starch
2. Cassava potato cassava kudzu root crushing stage
Cassava potato Cassava pueraria starch is mainly stored in the fleshy part of the roots, and only a small amount is stored in the endothelium. The purpose of crushing and crushing is to destroy the cassava potato cassava tissue structure, so that the tiny starch particles can be smoothly disintegrated from the roots and separated from the cells. The released starch is called free starch; what remains in the cells inside the residue is called bound starch.
Crushing is one of the most important processes in the processing of fresh potatoes. It is related to the yield of fresh potatoes and the quality of starch. The requirements for crushing are:
⒈ rupture the cells of fresh potatoes as much as possible, releasing more free starch particles;
⒉ Easy to separate. It is not expected that the skin dregs are too fine, and the skin dregs are not good for the separation of starch from other ingredients. Crushing and crushing too fine leaves is not good, it will destroy starch particles and increase the difficulty of separating fine dregs.
33 Cassava Potato Cassava Pueraria Starch Screening Stage
The tapioca potato cleaning residue is slender fiber, the volume is larger than the starch particles, the expansion coefficient is also larger than the starch particles, and the specific gravity is lighter than the starch particles. The broken pulp is made of water as the medium to make the starch slurry contained in the potato residue water. Filter out further.
4. Cassava potato cassava pueraria root cleaning and purification and concentrated essence stage
The specific gravity of mud and sand is greater than that of water, and it is greater than the specific gravity of starch particles. According to the principle of specific gravity separation, the use of cyclone to remove sand can achieve a more ideal effect. The specific gravity of yellow pulp is close to water and is higher than that of starch particles The specific gravity is light, and its shape is palm-shaped. The longer the processing period, the greater the performance of the glue. Sticking to the sieve and sticking starch particles, it is extremely difficult to separate. Therefore, it requires fresh raw materials, short process flow and timely separation.
5. Basic principles of dehydration
The concentrated starch syrup still contains more water, and it can be dried by further dehydration.
6. Basic principles of drying
The air drying (also called flash drying) generally used in starch factories is completed in an instant, so the moisture inside the starch particles is too late to gelatinize and has been dried, so gelatinization or degradation will not occur.
Air-drying is a co-current drying process, that is, a co-current process of wet powder material and hot air, consisting of two processes: heat transfer and mass transfer. When wet starch comes in contact with hot air, the hot air transfers heat energy to the surface of the wet starch. Then, it is transferred from the surface to the inside, and this process is the heat transfer process; at the same time, the moisture in the wet starch diffuses from the inside of the material to the starch surface in a liquid or gaseous state, and the starch surface diffuses into the hot air through the air film. It is a mass transfer process, that is, the high-temperature airflow and wet starch are used to carry out heat exchange in a drying tube in a balanced manner, so that the dried starch is in a powder form, and it can be packed into a warehouse after cooling.
Cassava, potatoes, cassava, pueraria and other potato starch processing equipment should be selected properly, improper selection, the starch output, quality, whiteness, etc. that are not up to standard will affect the later sales and processing vermicelli. Kaifeng Sida is a professional manufacturer specializing in cassava starch processing machine, potato starch processing equipment, and cassava starch processing equipment. We have 30 years of experience in starch processing research and development and sales.
