Description of production equipment used in cassava starch production line

With the continuous improvement of the technical level of cassava starch equipment in China, the cassava starch industry has shifted from the past small-scale production to large-scale production and mechanization.Chinese starch production technology is becoming mature.It is mainly reflected in the following aspects:

1. The starch equipment manufactured is efficient, reliable and energy saving.

2. Strong adaptability, capable of supporting starch production lines of different sizes with a daily output of 35-400 tons.

3. Low manufacturing cost. Compared with similar imported products, the cost is only 1/2 to 1/4 of the imported products, with high sex ratio.

As a result of having the advantage above, the starch equipment that China makes not only got the apprise of manufacturer of broad cassava starch, and also had uncertain competition power on international market.

In China, the process of making starch from cassava is generally as follows:

1. Take fresh cassava as raw material

Cleaning → shredding → screening → descaling → refining → concentration → dehydration → drying → packaging → storage

2. Take cassava dry slice as raw material

Cleaning → shredding → soaking → secondary shredding → sifting → descaling → refining → bleaching → concentration → dehydration → drying → packaging → storage

Through many years of production practice, the production process of cassava starch mentioned above only has the advantages of compact equipment arrangement, small footprint, low energy consumption, good quality of starch products, and the operation basically realizes mechanization, and high production efficiency, and the social environment has been greatly improved.


The following is according to the above cassava starch production line process line, the main equipment and production capacity, the main raw materials, power (water, electricity, steam) single consumption (per ton of commercial starch), cassava starch quality indicators are shown in annex 1.Among them, 95% of the products are superior grade or above.

1. Drum cleaning and peeling machine

Drum cleaning and peeling machine, mainly used to remove cassava peel, soil, sand and other debris.It is through the motor drive roller kept turning, cassava by conveyor from one end of the drum cleaning peeling machine, in which continuous turning, cassava and roller on the inner wall spiral strip, cassava and cassava, cassava and cylinder wall friction, coupled with high pressure water spray, the cassava peel, soil, gravel and other debris from the roller slag discharge hole, washed away in the tank, making cassava peeling, washing effect.

2. Shredder

Crushing is a key process in cassava processing.Commonly used equipment hammer - type mill, grater, bar - type mill, and so on.At present, the use of more hammer - type crusher.

3, curved screen

The working quality of the screening machine directly affects the starch recovery and quality, because the curved screen has the advantages of compact structure, reliable performance, good screening effect (the slag content under the screen is less than 0.02g/l), and long service life of the screen surface, it is widely used in the starch industry at present.Has gradually replaced the horizontal vibration screen, centrifugal screen.

4, dish separator

The application of the plate divider in starch production changes the traditional method of starch production.Its main function is to remove protein, fat and fine fiber impurities from starch milk, refined and concentrated starch milk.Is a more sophisticated starch separation equipment.

5. Horizontal scraper unloading centrifuge:

Horizontal scraper discharging centrifuge is a machine used for solid and liquid separation. It can be operated automatically and circulally under full speed operation from feeding to dewatering to discharging to feeding.

6. Negative pressure pulsed air drying system

Negative pressure pulsed air drying is a continuous and efficient fluidized drying method.The principle of its work is: under the state of negative pressure in the pipeline system, the hot air flow and suspended in the hot air tube powder material heat and mass exchange, due to the variation in the diameter of part of the air tube, generate pulsed air flow, increase the material inside the tube constantly rolling, hot air and starch get full contact.The moisture in the wet starch vaporizes and is carried away by hot air.To achieve the purpose of drying starch.The dried starch flows through the cyclone separator to the sieve.

Now kaifeng sida cassava starch mechanical automatic design, save time and effort, at the same time the quality of the product is more guaranteed, such as its online cleaning function, can make the whole production system (including all the pipes) be quickly and thoroughly cleaned, save manpower, and ensure the quality of the starch.
