Industrial potato starch making process

The potato starch making process and main potato starch processing machine:
Fresh potato (conveyor machine)- cleaning (dry sieve)- washing(rotary washing machine)- grinding (rasper)- starch and slag separation (centrifugal sieve, fine fiber sieve)- desanding (desander)- protein separation (hydrocyclone station)- dehydration (vacuum filter)- drying (flash dryer)-packing(semi-automatic packing machine)

* Cleaning: The weighted potato is cleaned by dry sieve to remove the foreign matters attached on raw potato. There is no water needed in this potato starch making process.

* Washing: Water is added in paddle washing machine for further removing the sand, dirt, soil and other impurities attached on potato in potato starch making process. Backwashing  method is adopted for better washing effect.

* Crushing and filtration section: The washed potato is subjected to high-strength rasper, of which the starch extraction rate is up to 95%. Multiple filtration means is adopted in potato starch making process to remove fiber impurities, and the free starch filtration rate is 98%.
The mainly potato starch processing machine equipped in this potato starch production plant includes: cutting machine, rasper, centrifugal sieve and fine fiber sieve.

* Sand removal unit
Then in potato starch making process,  the starch slurry is sent to a stirred starch tank, and then the starch is removed by a two-stage sand remover, and the collected sand is discharged by a butterfly valve.

* Protein separation unit: Hydrocyclone station is used in this process for potato starch making process. The starch is further concentrated and refined to remove non-starch components such as protein to improve the quality of the starch.

* Dehydrating: After the above process, the starch slurry still contains a lot of water, so it must be dehydrated to facilitate drying in potato starch making process. Peeler centrifuge is extensively used for dehydrating. The moisture content of wet starch after dehydration is required to be lower than 40%.

* Starch drying unit
potato starch making process requires to dry wet starch to the moisture content of 14%.  The dried product is collected by a high efficiency single cyclone and discharged by a low speed screw conveyor. The finished product is conveyed by air flow or screw conveyor for cooling. The cooled dry starch will be collected by a two-stage cyclone and sent to the sifter using a screw conveyor, sieved and packaged.

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...
