How to make potato starch?

A complete production line for how to make potato starch is composed of the following steps:
potato choosing-cleaning-washing-cutting-grating-separation-concerntration and refining-dehydrating-drying
How to make potato starch

1.Choosing: The quality of the raw potato has an important influence on the starch quality, therefore the potato choosing process is the first step towards a high quality potato starch product for how to make potato starch.It will be better to choose wholesome, no damage, fresh potato for processing.


2. Cleaning: The newly harvested potato roots contains weed, stone, siol, sand and other debris. Therefore they need to be cleaned first before further processing. Dry sieve is the most widely used cleaning machine for how to make potato starch is dry sieve. Designed with multiple inner spiral, this machine can achieve the transportation of potato during the potato starch production line.

3. Wahing: Washing process for how to make potato starch is used for removing the attached soil, sand, dirt and so on with rotary washing machine and wahsing water. DOING rotary washing machine adopts the counterwater washing principle to save water and improve washing effect.

4. Cutting: Cutting machine is used to cut potato into small pieces so that it is easier to be grated for how to make potato starch. The blade is treated by special technology and is durable.

5. Grating: After cutting, the small potato pieces are transported into rasper to grate. The process of potato changes into slurry is also the process of the bound starch turns into free starch for how to make potato starch. The rasper is bio-directional rasper which ensures a 94% breakage rate.

6.Separation: The next procedure of how to make potato starch is the concentrating process. The purpose of this process is to separate the fiber and starch slurry. Normally in order to have a better separation effect, this process will repeat four or five times according to different requirements of the different materials. For example, sweet potato normally needs five times, while potato requires four times for isolation of starch from potato. After every processing, it need take samples of the starch slurry to test the starch content. During the repeat process, the water can be recycled which is a good way to reduce the water consumption.

7. Concerntration and refining: This process is used for removing protein, cell sap and other impurities out of potato slurry. In the process of how to make potato starch, hydrocyclone station is the extensively used machine for this process. DOING full hydrocyclone technology can achieve the concentration, refining and recycling of starch which not only ensures the high quality of final potato starch but also prevent the waste of potato starch in processing.

8. Dehydrating: The dehydrating process is maily for reducing water content of potato milk so that it can meet the drying standard. Peeler centrifuge is used to dewater potato milk. It is required that the water content of potato starch is about 38%-40%.


9. Drying: Flash dryer is used for drying wet starch to meet starch production standard for how to make potato starch. The short time of material retention in the dry tower and high heat-exchange rate ensures the starch dried in seconds.

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...
