Professional potato starch making equipment process
The potato starch making process in Henan Doing Company adopts the wet processing technology of starch production which contains no additive. The whole process has the features of high degree of automation, mature technology, advanced equipment and scientific configuration. The process flow of potato starch production includes: potato weighing and conveying, cleaning & washing, grating, screening, concentration and refining, dewatering and drying.
1. Pretreatment of potato
a. Frsh potato weighing and conveying: This is the first step for potato starch making process. The potatoes are weighed on the weighbridge and stored in the potato yard. Then the raw materials are transported by conveyor to the potato cleaning and washing machine where the stones, sand and other attached objects are separated.
b. Cleaning and washing: The role of this process for potato starch making process is mainly to remove the sediment from the outer skin of the potato, and wash away the epidermis of the roots of the potato. Cleaning the fresh potatoes as raw materials for the production of starch is the basis for ensuring the quality of the starch. The cleaner the raw material, the better the quality of the starch.
2. Potato starch extraction unit
a. Crushing: The role of crushing is to destroy the structure of potato, so that tiny starch granules can be disintegrated and separated from the roots of potato. In potato starch making process, the widely used crushing machine is rasper. The potato starch processing machine relies on high-speed operation to disintegrate potato so that the starch granules are continuously separated.
b. Screening: This process is mainly for the separation of starch and fiber. Centrifuge sieve utilizes high speed centrifugal force to remove the fiber and starch. To achieve better separation effect, potato starch production plant normally use multi-stage centrifuge sieve in potato starch making process.
c. Desanding: Desander is mainly used for remove sand content from starch slurry. Due to sand in potato starch slurry will influence the taste of the final starch, the desanding is a necessary procedure in potato starch making process. According to the principle of specific gravity separation, desander can effectively separete the sand from starch.
d. Concentration and refining: The function of this process is to separate insoluble protein and residual soluble protein and other impurities from the starch slurry, thereby achieving the purpose of washing, refining and concentrating the starch slurry. The potato starch making process uses a 12-stage hydrocyclone station to wash, refine and concentrate the starch slurry.
3.Starch dewatering and drying unit
a. Dewatering: After that, the potato starch need to be dewatered. Vacuum filer is the main machine in potato starch making process. It take use of negative pressure principle. When working, the starch is adsorbed on the filter cloth of the drum and is scraped off by the fixed scraper. While the filtrate enters the separator, so as to achieve the purpose of separation of starch and water.
b. Starch drying: For drying process, we use flash dryer for the process of potato starch making process. The whole process time of air drying is completed in an instant, so the internal moisture of the starch granules is dried before gelatinized, and this process consists of heat transfer and mass transfer.
