The different between potato flour and potato starch

Potato starch plant

The way to remember the difference is that potato flour is made from whole potatoes, while potato starch is made only from the starch of the potato.


Potato Flour vs. Potato Starch

Potato Flour production and application

Potato flour is made from whole potatoes (most of the time even the peel is included). The potatoes can be raw or cooked. Either way they are first dried then ground into flour.

The result is a heavy, cream colored flour with a distinct potato flavor. The flour readily absorbs liquid (similar to coconut flour in this regard), so it works best when incorporated into gluten-free flour blends in small amounts. Too much potato flour in a recipe will cause the finished product to be dense and gummy. For example, a muffin with too much potato flour would never fully cook through.


Potato Starch production and application

Potato starch is a very fine white powder starch, similar in texture to corn starch. If you’re not very careful when working with and measuring potato starch, you can create quite a cloud in the kitchen!

It is made from the dried starch component of peeled potatoes. It has no potato flavor so works well in most recipes, sweet or savory.

As part of the starch component of a gluten free flour blend, potato starch lends a light, fluffy texture to baked goods.

It is also a great thickener in gravies, sauces, and even in custards and puddings, which typically use corn starch.

Sweet potato starch processing plant

Sweet potato starch processing plant is decomposed into pulp, screening, separation and drying four main section; is also divided into transportation, cleaning, pulp, impregnation, screening, bleaching, bed cleaning, separation, dehydration, drying, air-cooled packaging twelve control points.

Sweet potato starch processing plant 

1.Sweet potato starch processing plant Washing Unit:

Washing effect: Mainly to clean sweet potato outer epidermis stained with mud, and wash to remove sweet potato root epidermis.

Our rotary cleaning machine, its structure is horizontal cylinder, with coarse washing area (including the drainage hole), bathing area, net washing area (including the drainage hole), spray nozzle, rifle, stirring rod, etc. It depends on the motor drive gear rotating cylinder, with water as medium spraying, washing, plunge grinding to remove sediment and potato skins. The washing requirement is: remove sediment clean, peel requirements above 80%.

2. Sweet potato starch processing plant Broken Unit :

Our disintegrator of flying hammer type, its structure composed by the machine cover, enclosure, frame, main shaft, sieve plate, hammer, electric motor, etc. It is a kind of high speed flying hammer pulp machine, with compact structure, stable running, easy to install and use, easy maintenance overhaul advantages.

Secondary breaking through the 1.4 mm sieve plate, is still the sweet potato starch processing plant organization structure, makes the small starch granules can be more smoothly, more cleanly separated from cassava collapse of structure.

3. Sweet potato starch processing plant Starch Extraction/Fiber Separation Unit:

Sweet potato residue is slender fiber, volume is larger than the starch granules, the proportion is lighter than the starch granules. The broken puree, with water as the medium, mixing evenly, and then to pump evenly feed sieving equipment (including the flat vibration sieve, sieve, sieve, centrifugal rolling pressure curved sieve etc.), under the action of the mechanical oscillation, roll, centrifugal, hydraulic flushing, repeated washing to puree. Butterfly separator, liquid rotary separator, which is to be designed according to the principle of density separation.

Sweet potato starch, generally requires twice separate, can achieve more ideal effect.

4.Sweet potato starch processing plant Dewatering Unit:

Wet starch general water cut of about 55%. Butterfly separator, liquid rotary separator concentrated whey isolated from the general to 20 baume degree, all need to again centrifugal dehydration, drying efficiency, saves energy.

5. Sweet potato starch processing plant Starch Dry Unit:

The starch factory usually uses air drying (also called flash drying). The whole process time is done in a flash, so the internal moisture has been dry before pasting , so the pasting or degradation phenomenon will not occur.

The product after drying uses high efficiency cyclone to collect, finished products of drying machine use pneumatic conveyor or screw conveyor to cool, cooling dry starch will use two stage cyclone separator collection and screw conveyor sends to the sieving machine, after screening to package warehousing.Then the whole sweet potato starch processing plant completes.

The technical processing of potato starch processing machine

Potato starch processing flow

Here below is the details of potato starch processing machine

(1) Raw material receiving and washing:

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:

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:

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:

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:

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

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.

(9) Vacuum dewatering unit:

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.

(10) Air drying unit: 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.
