Extraction of starch from potato procedure

The complete extraction of starch from potato procedure are as follows:
- Cleaning and washing: The cleaning and washing are the first step for extraction of starch from potato procedure.  The potato raw material is rolled and transported along with the machine to remove the sand, stone, weed and other impurities.

- potato grating: In extraction of starch from potato procedure, it is necessary to rupture all cell walls in order to release the starch granules. This is the most important procedure for it determines the starch yield. In view of this result, it is important to choose high efficient potato starch processing machine for grating.

- Screening: To separate and purify starch by screening in extraction of starch from potato procedure. At present, centrifuge sieve is mainly used to remove fine slag. Multiple screening or counterflow washing process is generally adopted.

- Desanding: To remove sand out of starch pulp through cyclone desander to purify potato starch and reduce burden of the subsequent equipment for extraction of starch from potato procedure.

- Concentration and refining: The function of this extraction of starch from potato procedure is to remove insoluble protein and residual soluble protein and other impurities from the starch slurry, thereby achieving the purpose of washing, refining and concentrating the starch milk.

- Dewatering & drying: Starch milk is then dewatered by a peeler centrifuge to yield the product with 38% moisture content from starch milk to starch cake. Then moisture content is further dried in extraction of starch from potato procedure by subjecting the starch cake to a flash dryer, where the water content is reduced from 38% to 12-14% in potato starch production plant.

The advantages of potato starch processing machine for cleaning & washing:
First, the funnel type feeding reduces the difficulty of manually feeding, it makes the feeding way more convenient and easier.
Second, in the middle of the potato starch processing machine, the fresh potato moves in a circular motion along the wall of the cylinder. The comprehensive washing distance is greater than 20 meters. And can partially discharge sediment, stone and skin residue through the sewage outlet.
Third, the potato starch processing machine for washing with both the washing and conveying functions, there is no need to add a conveyor machine, which is highly efficient. (8 tons of potato can be washed per hour)

Potato starch production plant and machinery

Image
The process and main equipment used in potato starch production plant Fresh potato (conveyor)-cleaning and washing(dry sieve, rotary washing machine)-crushing (rasper)-starch slurry separation (centrifugal sieve, fine fiber sieve)-sand removal (desander) -protein separation (hydrocyclone station)-dehydration(vacuum filter)-Drying (flash dryer) Potato starch production plant 1. Raw material cleaning and washing The role of this unit in potato starch production plant 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. Grating potato to extract starch The grinding unit is one of the most important part for potato starch production plant which determines the potato starch extraction rate. High-efficiency rasping...

How potato starch is made ?

Image
The process flow of how potato starch is made includes: transportation, potato cleaning, washing, grating, separating, concentration and refining, dehydration, drying and packing. Step 1. Transportation: The potato is transported from the storage yard to the cleaning machine by using a conveyor, and it is required to ensure the sufficient supply of the raw materials of the process. In the process of how potato starch is made , it is necessary to prevent the inclusion of iron, nails, stones, wood and other debris. If debris is found, it should be picked up in time. Step 2. Cleaning and washing: For the question of how potato starch is made, potatoes are fed through the feed hopper and transported into cleaning machine for removing the small stones, dirt and other debris of raw materials. After stone removal, potatoes are washed in a rotary washing machine. The potatoes are constantly rolling and rubbing in the water, which can make the soil on the potato peel off to achieve a ...

How much does the potato starch production line cost?

Image
How much does the potato starch production line cost? It depends on the scale of potato starch production line you need and the potato starch processing machine supplier you choose. Why do you say that? Next, Henan Jinrui will give you an analysis. 1. The cost of potato starch production line varies greatly depending on the scale. There are three types of potato starch production lines according to their output: small potato starch production lines, medium potato starch production lines and large potato starch production lines. The higher the output and the degree of automation, the higher the configuration of potato starch processing machines and the more equipment, so the cost is more expensive.   2. The selected potato starch production line supplier is different, the quotation received will also be different. This is obvious. Henan Jinrui recommends that you choose potato starch manufacturing process supplier that integrates production and sales. In this way, the additional c...
