Potato starch making process

The potato starch making process in Henan Doing Company adopts the wet processing technology of starch production which contains no additive. The whole process has the features of high degree of automation, mature technology, advanced equipment and scientific configuration. The process flow of potato starch production includes: potato cleaning process, washing process, grating process, separating process, concentration and refining process, dehydration process and drying process.
Potato starch making process 

1.Cleaning: In potato starch making process, the first step is cleaning the raw material. The industrial potato processing equipment for cleaning is dry sieve which can effectively remove the small stones, dirt, sand and other impurities out of potato. With the help of the inner spirals, the potato move steady forward without damage the raw material.

2.Washing: The cleaned potato is conveyed to the paddle washing machine which is a widely used potato starch processing machine in potato starch making process. The paddle washing machine is a high efficiency washing machine which takes countercurrent washing principle. The water moves in the converse direction with the potato so that the washing effect is greatly improved. The large capacity and easy handling characteristics of this machine makes it save labors for the factory.

3.Crushing: After washing, the potato stays in the clean silo to drain the water, then it is transported into the rasper by screw feeder. The crushing process is an important process which determines the starch yield in potato starch making process. Therefore it will be better to choose a machine with high crushing coefficiency and high starch extration rate. DOING rasper is such a machine to satisfy your need. By fully introduces advanced technology from home and abroad,the starch breaking rate of the rasper is above 94%.

4.Separation: The grated potato slurry need to be further processed to remove the impurities from starch in potato starch making process. 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 process, and the starch content of the residue should less than 35%. And fine fiber sieve is also used to further remove the small fiber so as to improve the fineness and quality of potato starch.

5.Desanding: Due to the high sand content in starch, the desander is needed to remove sand form the starch slurry in potato starch making process. The desander can remove sand from starch at one time and improve the product quality to a higher level. The desander separates sand from starch by using different densities of sand and starch.

6.Concentrating and refining: After separating, the starch milk goes into the concentrating and refining unit to further separating the protein and cell sap.
In potato starch making process, the starch milk is firstly concerntrated through the hydrocyclone station, while the overflow of cell sap goes into recycling hydrocyclone station to recycle the containing starch in potato starch processing plant.

7.Dewatering: After that, the potato starch need to be dewatered in potato starch making process. Vacuum filer is the main machine for this process. It take use of negative pressure principle. When working, the starch is adsorbed on the filter cloth of the drum and is scraped off by the fixed scraper. While the filtrate enters the separator, so as to achieve the purpose of separation of starch and water.

8.Drying: After dewatering, the water content in starch is still high so it need the drying in potato starch making process. The potato starch processing machine used in this process is flash dryer. The flash dryer adopts the negative pressure drying system which can effectively reduces the loss of the starch and meanwhile purifies the working environment. The high speed hot air dry the starch just in 2-3 seconds which has an significant energy saving effect.

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...
