Selection of raw material: in order to ensure the powdery rate and the quality of lotus root powder, the raw material used in processing should be the fresh and mature lotus root with neat appearance, uniform thickness, normal color, smooth and clean individual surface and no obvious defects. Cleaning: the purpose of cleaning is to remove the sediment on the surface of the raw material.
Comminution and filtration: the purpose of comminution is to destroy the structure of the material so that the tiny starch particles can be separated from the lotus root successfully. Starch extraction, also known as slurry and slag separation or separation, is the key link in starch processing, which directly affects the extraction rate and quality of starch.
Dust removal and purification. The main purpose is to further remove the sediment of the material.
Concentrated refining. According to the property of lotus root starch granules design, the starch slurry can be concentrated, and the non-starch components in lotus root starch can be completely separated, so that the concentration of the starch milk discharged by the first-stage cyclone after can reach 23Be ', whiteness, purity standards, is an ideal choice for the starch washing equipment.
Dehydration. There is still a lot of water in the concentrated starch slurry, so it is necessary to further remove the water in the material before entering the drying section. Dehydration can choose three - foot dehydrator, large plants can choose a scraper centrifuge.
Drying: air drying is used to dry, air dryer is the use of high speed flow of hot air to make the wet starch suspended in the process of air drying. It has the characteristics of high heat transfer coefficient, large heat transfer area and short drying time.
Starch is cooled with sifted packaging
After drying the lotus root powder temperature is higher, after rapid cooling to ensure the viscosity of the lotus root powder, at this time the vibrating sifter will come in handy, the cooled lotus root powder into the vibrating sifter sieve purification to remove the silt and debris in the lotus root powder, so as to improve the purity and taste of the product.
In the process of high flow, the high performance screen machine can quickly remove the large or small particles with low content. The vibrating screen separator can quickly remove the insoluble solid substance in all kinds of slurry and continuously discharge slag, finally get the desired effect
The main features of lotus root powder vibrating screen:
1, high efficiency, sophisticated design and durability, any powder, mucus can be screened;
2, easy network, simple operation, easy to clean;
3, mesh is not blocked, powder is not flying, can be sifted to 400 mesh or 0.028mm;
4, impurities, coarse material automatic discharge, can be continuous operation
Application scope:
In addition to this, the vibrating screen of lotus root powder can be widely used in chemical industry, food industry, metallurgy and mining industry, public hazard treatment and other industries. In other industries such as: carbon black, light calcium, additives, pearl powder is also very common. Any particles, powder, mucus can be screened within a certain range. Sieve to 500 mesh or 0.028mm, filter *** to 5 micron. Classification screening, can screen one to five layers of screen, can carry out two to six grades of sorting or filtering.
