Industrial potato starch production plant equipment

The potato is a good material for potato starch production plant because it has a high starch content, but contains less protein and fat, and the starch content is 15-25%. Some unique properties of potato starch are not replaceable by other starches, so they are widely used in the food industry. Meanwhile because of their good edible properties, they are more widely used in the field of starch processing industry.

The process flow is potato starch manufacturing process
Raw potato - → hydraulic conveying - → cleaning to stone - → drum cleaning - → crushing - → separation - → sand removal - → concentrated desiccation cyclone separation - → purification and purification - → vacuum dehydration - → air drying - → package finished products.

1. Potato cleaning: potato starch production plant requires the raw material be cleaned thoroughly. For the cleanness of raw material has an influence on the following separation and purification of potato starch. Dry sieve is used for cleaning process which can effectively remove the sand, soil, weed and other debris.

2. Ppotato washing: The washing process 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 production plant.

3. Crushing section: This is the most important step in potato starch production plant. The rasper is used to crush the potato into slurry so as to release the free starch in the potato cell. The extraction rate of starch is determined by this machine. DOING rasper is an advanced crushing machine which fully absorbs technology from home and abroad, and the breakage rate can reach at around 95%.

4. Separating section: The grated potato slurry need to be further processed to remove the impurities from starch. Centrifuge sieve is used to separating fiber and potato starch. Multiple screening or countercurrent washing processes are generally adopted. It is required that after the separating and washing of potato starch production plant, and the starch content of the residue should less than 35%.

5. Concentration and refining section: The function of this process 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. At present, the hydrocyclone station is commonly used for washing, refining and concentrating in potato starch production plant.

6  Dehydration section: Starch slurry stays in starch jar after refining in potato starch production plant, and then is sent to vacuum filter for dehydrating. The wet starch water content after dehydration is 38-40% by potato starch machine.

7. Drying and packing section: The wet starch is then conveyed into air flow flash dryer for frying. The steam pressure is controlled at 0.8 MPa. The potato starch production plant requires that the moisture content of the finished starch is about 13.5% after drying. Packing and warehousing requires a sufficient number of bags, and timely packing for storage.

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...
