Potato-Starch-Production-Line

Potato starch and potato starch derivatives are used in many recipes, for example in noodles, wine gums, cocktail nuts, potato chips, hot dog sausages, bakery cream and instant soups and sauces, in gluten-free recipes in kosher foods for Passover and in Asian cuisine. In pastry, e. G. Sponge cake, it is used to keep the cake moist and give a soft texture. It is also occasionally used in the preparation of pre-packed grated cheese, to reduce sweating and binding.

 

Potato starch is used in technical applications as wallpaper adhesive, for textile finishing and textile sizing, in paper coating and sizing and as an adhesive in paper sacks and gummed tape.

Process description of potato starch production line:

Potato transporting, De-stoning, Washing, Rasping, De-sanding, Fibre extraction, Concentration and refining, Fine fibre sieving, Dewatering, Drying, Packing

(1) Raw material receiving and washing during the potato starch processing machines:
The potato is carried besides the storage pool after weighing. Firstly, it goes through the vibration sieve for removing the stones and sand. Then the pre-cleaned potato falls on the belt conveyer and enters into the storage pool, and the rubbish will be carried away by truck.
(2) De-stone and washing unit of potato starch processing machines:
Potato is transferred into the screw destone machine to be cleaned by water flow. The small sand and stone go through the rotary screen then meet with bigger size stone which was stopped and sent back to the entrance of de-stone machine. Most of sand and stone are removed out of de-stone machine.
Then the potato is sent by bulk elevator into temporary storage in which it can stay 2 hours.
(3) Crushing unit of potato starch processing machines:
The Crushing unit is the most important step for extracting potato starch. The feeding screw combined at bottom of the storage tank pumped the clean potato into milling machine. Highly-efficient milling machine will release the starch in potato at most.
(4) Centrifugal extracting unit of potato starch processing machines:
The mixture is transferred to the 3 stage centrifugal sieves, each sieve works with a fiber pump and a defoam pump. The mixture enters into each sieve to separate residue and starch. After 3 stages continuous washing and separation, the filtrate is sent to concentration and refining unit, and the residue is sent to the residue dewatering unit.
(5) Potato residue dewatering unit of potato starch processing machines:
The potato residue will be pumped to the centrifugal sieve for dewatering, the centrifugal sieve works like the extraction sieve. Then the screw conveyor discharges the residue out of the process, and the water will go back to the process water system.
(6) Concentration and refining unit of potato starch processing machines
The starch milk from centrifugal sieve goes into the 16 stages of refining hydro-cyclone, and fresh water comes into the cyclone from the end of system. Firstly, starch milk is pumped into 3 stages of concentration unit to remove the water, then the condensed starch milk enter the next 13 stages of washing unit, and the overflow enters into another 2 stages of recycle unit to recycle starch. Most of the effluent with fiber is discharged out of the process, and a little part goes back to the process water system. Finally, the condensed starch slurry is pumped into the starch slurry storage tank.
(7) Vacuum dewatering unit of potato starch processing machines:
The starch slurry is pumped into inlet tank of vacuum dewatering machine. Then the vacuum rotary drum will adsorb the starch on the drum surface and the filtrate is transferred out of the system by filtrate pump. The filter cake on the drum will be peeled off by peeler and then transferred to the air dryer by screw conveyor.
(8) Air drying unit of potato starch processing machines:
After dewatering process, the air dryer will dry the starch to the required moisture of the commercial starch.
The package machine will be according to the customers’ special requirements.
