Wheat starch processing is an industry in which wheat is ground into wheat flour, and then the wheat flour is further processed to obtain wheat starch and gluten.
Wheat starch processing process
Henan Yide has a significant advantage in starch processing production line. We have China's Class A design qualification and professional team, which can design crafts and custom-made equipment for customers. The following is the conventional process:
Main equipments of wheat starch machinery
Double helix gluten machine (integrated machine for flour and noodle washing), gluten round screen, wheat starch centrifugal screen, wheat starch cyclone group, wheat starch dehydrator, wheat starch drying equipment, wheat starch packaging Machine, gluten drying equipment.
Detailed introduction of main starch processing sections
1. Making dough
Add flour and water in proportion, and use a large-scale gluten machine to fully mix to knead the flour into a dough. Then place it to make the gluten swell and bond to each other, so that the starch is easy to separate.
2. Sieving crushed gluten
Using a gravity curved screen and an appropriate mesh screen surface, the crushed gluten slides down from the screen surface by its own gravity. Because there is no external pressure, the crushed gluten is not easily mixed into the slurry through the screen surface, which can reduce the blockage of the fine screen and increase the fine Sieve efficiency.
3. Coarse pulp separation and concentration, refined washing
The traditional process is to use a horizontal screw centrifuge. Because of its low separation factor, B-starch is discharged with the gluten liquid, separated by a disc separator, and concentrated to obtain B-starch. The underflow of the decanter is washed with water to obtain A-starch.
4. Dehydration of starch slurry
The dehydration of starch milk usually uses three-foot centrifuges and horizontal scraper centrifuges. Due to the high energy consumption and high annual maintenance costs of scraper centrifuges, vacuum filters have been used in recent years. Due to the firmness of the filter cake after dehydration of wheat starch, its production efficiency is lower than that of other types of starch. After the demonstration and discussion between the two parties, the choice of their equipment should be determined.
5. Starch drying
Due to the high density and hardness of the wheat starch dehydrated filter cake, it is not suitable to use negative pressure drying equipment. We use airflow collision dryers. The distinctive features of this drying equipment are high drying strength, high thermal efficiency, low energy consumption, and a 50% reduction in overall height.
