Extraction of starch from potato procedure

The extraction of starch from potato procedure in Henan Doing Company adopts the wet processing technology of starch production which contains no additive. The whole process has the features of high degree of automation, mature technology, advanced equipment and scientific configuration. The process flow of potato starch production includes: potato cleaning process, washing process, grating process, separating process, concentration and refining process, dehydration process and drying process.
Extraction of starch from potato procedure

Here is the detail introduction of extraction of starch from potato procedure
1.Raw material pretreatment process
a. Raw material sorting: This section of extraction of starch from potato procedure is to choose high quality potato roots which is not mildewed, not degraded, and free of insects to ensure starch quality.

b. Cleaning: Then is the cleaning part for extraction of starch from potato procedure. The dry sieve is the mainly used machine for this process whose main function is to remove the sand, soil, weed and so on. As a potato starch processing machine, dry sieve features with reasonable rotating speed and stable running.

c. Washing: The washing process for extraction of starch from potato procedure is carried out by paddle washing machine. potato raw material is rolled along with the wall of the cylinder, and is sprayed, washed, bathed, mixed, and peeled with water as a medium in potato starch extraction process.

2.Extraction of potato starch process
This is the most important step for extraction of starch from potato procedure. The main purpose of this section is mainly for grate the potato into starch slurry so as to release the starch in the cell of potato. The grating rate determines the starch extraction rate and the end products yield. The higher the grating rate, the higher starch extraction rate. Rasper is widely used grating machine for starch extraction. DOING rasper adopts international advanced technology which features with high breaking rate and high starch extraction rate.

3. Starch slurry separation and refining process
a. Starch slurry separation: For extraction of starch from potato procedure, the separation is another important procedure. We use multi stage centrifuge sieve for separating fiber from starch in potato starch processing plant.  And fine fiber sieve is added for further removing the fine fibers out of starch slurry.

b. Concentration and refining: Hydrocyclone station is widely used potato starch processing machine in extraction of starch from potato procedure for this process. The hydrocyclone station is composed of multistage cyclone in a certain way. According to the processing function of each stage cyclone in the cyclone station, different number of cyclone pipes and a feed pump need to be installed. The whole unit is independent in the process, compact in structure and convenient in installation.

4. Starch dewatering and drying process
a. Dewatering: After concentration and refining process, the concentrated starch milk still contains a large amount of water, and thus must be dehydrated to facilitate drying in extraction of starch from potato procedure. It is required that the wet starch has a low moisture content of 38% after dehydration.

b. Drying and packing: This section of extraction of starch from potato procedure is for quickly removing moisture from wet potato starch. The equipped machine in this section is flash dryer which has the features of high drying strength, strong evaporation capacity, short drying time and good starch quality. Then the dried starch is packed by semi-automatic packing machine for sale.

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...
