Extraction of starch from potato procedure
a.Choosing and weighting: Before processing, it is important to choose proper potato varieties for furthur processing in extraction of starch from potato procedure.The quality of the raw potato have an great influence on the final starch quality. Therefore it will be better to choose high quality potato. After choosing,the collected potato is weighted and stored in the potato yard for deep procesing.
b.Cleaning and washing: After being weighted and sorted, the fresh potato will be firstly transported into the cleaning machine to clean the sand, small stones, dirt and other impurities for extraction of starch from potato procedure. Then the cleaned potato will be transported into the washing machine. To achieve a better cleaning effect, it will be better to use the rotary washing machine, so that the impurities such as sand, stone, iron items will be thoroughly cleaned in potato starch production plant.
Potato grinding machine
a.Grinding: Potato starch processing line emphasize grinding as one of the most important working procedure in extraction of starch from potato procedure, it relates to the fresh potato starch yield and quality of starch. Therefore the grinding process requires to break potato cell as much as possible to release more free starch granules.
b.Separating: The separating process for extraction of starch from potato procedure is mainly for the separation of fiber and the potato starch. The centrifuge sieve is used in this process. The centrifuge sieve utilizes the high speed centrifugal force to separate fiber and starch. Normally in order to achieve better separation effect, potato starch processing line adopts multi-stage centrifuge 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 for extraction of starch from potato procedure. According to the principle of specific gravity separation, desander can effectively separete the sand from starch.
d.Concentration and refining: Hydrocyclone station is a high efficient potato starch machine mainly which is mainly used for remove protein, fine fiber, cell sap out of slurry for extraction of starch from potato procedure. Doing Company full hydrocyclone technology includes concentration, refining and recycling process. The hydrocyclone pipe is made of strengthened nylon material.
Potato starch dewatering machine
a.Dewatering: The water content of starch milk coming out of hydrocyclone station is too large to dry directly. Therefore, it is necessary to dehydrate starch milk first to make sure the water content of starch is about 40% for extraction of starch from potato procedure. With the help of vacuum filter, the starch milk is sucked into the drum, while the filtrate goes into the filtrate separation tank and pumped away by the filtrate pump. Then the starch goes into the air dryer feed hopper by cleaning conveyor belt.
b.Drying and packing: The dehydrated starch cake is transported to the feed inlet of the flash dryer through the conveyor belt and enters the hoist through the feeder. The heat source of flash dryer is steam heat exchanger. The wet starch is heated by the high speed hot air and the water evaporates. After drying for extraction of starch from potato procedure, the wet air leaves the cyclone separator and is discharged into the atmosphere by the ventilator. The collected starch is packaged into finished products by packaging machine.
