Professional manufacturer supply cassava/potato starch processing equipment 

Starch is kind of white powder that could be extracted from cassava, potato and sweet potato. It is widely used in food and non-food industry. Machines used in starch manufacturing directly influence the quality of final starch.

Flow Chart of starch manufacturing

Starch manufacturing procedures are mainly divided into three parts:

(1) Pretreatment of raw materials (also refers to the cleaning process of starch manufacturing): The raw materials are firstly transported to the dry sieve through the belt conveyor. Dirt, gravel, weeds and other impurities are removed along with the inner spiral belt rotating in the Dry Sieve; The raw materials are then transported to the Paddle Washer or Rotary Washer for second cleaning and washing.
(2) Processing section of starch manufacturing: The cleaned raw material firstly enters the Cutting Machine. It is cut into small pieces and then enters Rasper, which reduce the load of Rasper as well as equipment damage. Starch slurry coming out from Rasper enters Centrifugal Sieve to separate fiber and other impurities and then go through Fine Sieve to remove finer fiber residue that cannot eliminate in centrifugal sieve. Disc Separator and Hydrocyclone are following to remove impurities (such as protein, fat etc) and do starch concentration and purification. At last, concentrated starch slurry goes in vacuum dehydration and come out damp starch with moisture content of 38-40%.
(3) Drying process of starch manufacturing: The starch from the vacuum dehydrator is further conveyed to the drying system for drying, resulting in about 13% moisture content of the finished product. Final starch products would be packaged by Automatic Packing Machine for easy storage.

Main Equipment in starch production line

DRY SIEVE: Widely used in impurities pre-removal for starch production. It's used to remove dirt, sand, small stones, weeds and other impurities that are attached on the surface of potato/sweet potato/cassava.

PADDLE WASHER: Mainly used in the second washing section to clean raw material completely.

CUTTING MACHINE: Cut raw material into small pieces, 3-5cm.

RASPER: Crush pieced materials into slurry. Release starch particles from cell.

CENTRIFUGAL SIEVE: Separate the fine fiber (pulp) from the starch slurry which is widely used in big and middle-sized starch factories for the extraction of tuber and wheat starch.

HYDROCYCLONE: Designed to get rid of related substances such as fiber and protein in the starch milk.

VACUUM FILTER: Dehydrate starch slurry into wet cakes with moisture content 38-42%.

DRYING SYSTEM: Dehydrated product is sent to drying system and come out final starch with moisture content 12-14%.
