Potato starch production plant and machinery

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 machine allows the starch granules in potato cells to be completely released, ensuring that the combined starch content in the potato residue is minimized. DOING rasper is a high efficient machine which fully absorbs international advanced technology and has the features of high extraction rate and high grinding rate.

3. Separating the unnecessary parts and extracting pure potato starch.
First of all, according to the physical and safe way, by working with the centrifuge sieve, the potato starch processing machine will play the role of separating the fiber in raw material. Then use a desander to remove the sand content which influence taste of potato starch. Hydrocyclone station is a potato starch machine can recover the lost fine fibers, starch molecules in the protein and cell fluid, thereby increasing production, followed by the role of refined concentration in potato starch production plant.

4. Starch dehydration process
The moisture content of the starch milk coming out from the hydrocyclone station is too large to be directly dried. Therefore, the starch milk should be dehydrated first in potato starch production plant, so that the moisture content of the starch is about 38%-40%. Vacuum filter takes use of negative pressure to complete the dehydration of starch.


5. Starch drying process
For drying process, we use flash dryer for this potato starch production plant. The whole process time of air drying is completed in an instant, so the internal moisture of the starch granules is dried before gelatinized.

The potato starch processing machine made by Henan Doing Machinery has following characteristics:
1. Excellent craftsmanship, beautiful appearance and compact layout;
2. Use fewer people, less labor intensive, high degree of automation, one-stop production from washing potato to dry;
3. Low energy consumption, water saving, power saving, and low processing cost;
4. Stable performance, easy operation and maintenance.

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...
