Advanced technology of potato starch processing plant

Advanced technology of potato starch processing plant

Our potato starch processing plant is designed based on European processing technology-hydrocyclone technology and has the following advantages:

1. Efficient, high-yield starch, high product quality.

2. Easy to operate.

3. Minimal water and power consumption.

4. Low maintenance cost and simple operation. The crushing system, the filter press system, the concentration and purification system, and the dehydration and drying system are composed of five parts. The potato starch production line combines the characteristics of cleaning, crushing, concentration, purification, and drying to realize automatic continuous operation of potato starch production. The following are its main functions:

1. Our potato starch processing equipment adopts a unique cleaning, crushing and filtering system, fully designed with manual principles, and with domestic and foreign equipment technical indicators, with high efficiency, energy saving, high starch extraction rate, high economic efficiency, and strong practicability. .

2. The separation section adopts multi-stage filtration, and multiple extrusions during the circulation process overcome the defects that the pure filter does not leak water and the starch can not be completely extracted, and greatly improves the extraction yield of starch, which can reach more than 90%.

3. High starch extraction rate. The potato starch production line adopts three-stage extrusion and multi-stage filtration technology, which effectively improves the starch extraction rate.

The detailed description of the steps in the potato starch processing plant is as follows.

Step 1: Cleaning and washing

The potatoes will be cleaned and cleaned by the cleaning conveyor and stone remover during the cleaning process.

Step 2: Milling/Roughing

After cleaning and stone removal, the potatoes are transported to a hammer mill or sander. After grinding or coarse grinding, the mashed potatoes are pumped to the next starch extraction process.

Step 3: Extract starch

Starch extraction is the separation of fiber and other insoluble impurities in potato mash. This will require centrifugal screens and pressure screens.

Step 4: Centrifugal screen

The fiber residue stays for a long time, the cleaning rate is high, and only a few cleaning devices are needed, and the investment is small.

Step 5: Desanding

After separating the fibers, the starch milk is pumped to a desander cyclone, and the sand is collected in a collection container and can be discharged regularly.

Step 6: Refining starch milk

Hydrocyclones are used for starch milk concentration and protein separation purposes. The starch milk in the hydrocyclone will be separated in two ways, one for starch milk and the other for protein and soluble impurities. Then, the purified and concentrated starch milk leaves the hydrocyclone and enters the vacuum filter for dehydration.

Step 7: Dehydrate starch

The dehydration principle of the vacuum dehydrator is to separate wet starch and water through a vacuum filter. The water will enter the drum through the filter cloth and be pumped away. The wet starch will stay on the surface of the filter cloth and then be scraped off by the scraper and fall into the inlet of the dryer.

Step 8: Starch drying and screening

The wet starch will be dried to commercial demand by hot air in the starch dryer. The dried starch is then sieved to the desired size, and then directly packaged.

The potato starch production process of the potato starch processing plant includes the following steps, for example, transportation and unloading of potatoes, washing and washing, wet or coarse grinding, starch extraction, degreasing, starch milk refining, refined starch milk dehydration and starch drying. cut costs.
