How to produce high quality cassava starch from cassava ?

Date:Apr 10, 2017/ FAQ/ Chat online
Starch is one of the most abundant substances in nature, a renewable and almost unlimited resource. High quality cassava starch is produced primarily by the wet milling of fresh cassava roots to release the starch and purfied the starch . High quality cassava starch has more bigger market , it can be used to produce such diverse products as food, paper, textiles, adhesives, beverages, confectionery, pharmaceuticals, and building materials.

How to produce high quality cassava starch from cassava ? 

Our company can supply the complete cassava starch processing machine with hydro cyclone refining method for producing high quality cassava starch from cassava . The complete production process of producing high quality cassava starch from cassava include cassava cleaning and washing , cassava milling  , cassava starch extraction , cassava starch refining and concentration , cassava starch dehydration and drying process.

The detail cassava starch production process as below : 

1. Cassava cleaning and washing process of  cassava starch production machine
The cassava that through the quality inspection process will be sent to sieve to separate the soil and sand. After that, the cassava is sent to the washing process to clean up the residue. The cassava is then sent to the hewing and peeling machine to minimize the size of the cassava and separate the peel before entering the grinder.
2. Cassava milling  process of cassava starch production machine
The clean cassava is sent to the hammer mill to mill the cleaned cassava into cassava slurry. This process is to observe the smaller pieces of cassava in order to enhance the efficiency for the extraction of starch.

4. Cassava starch extraction process of cassava starch production machine
After wet milling ,  the cassava slurry will be sent to the centrifuge screen to extract the starch from the cellulose. In general, the extraction process is carried out several times. Most factories normally use 3 sets of centrifuge screen ; however, large factories may use 4 continuous sets. The first set will be rough extraction using mesh with a size of 60-80 mesh and the last set will be fine extraction using the filter with a size of 90 mesh. In this process, they normally add sulfuric acid to inhibit the function of microorganisms, which changes starch molecules into lactic acid. The cassava pulp from the extraction process contains large amounts of water and low starch content. The cassava pulp will be extracted from the starch water in order to be introduced into the waste compactor and to be dried in the sun, to be mixed as animal feed .
5. Cassava starch refining and concentration process of cassava starch production machine
In order to prevent chemical reactions and biochemical reactions from microorganisms, which would result in a reduction of the quality of starch, the time taken for the starch production must be as short as possible. Therefore, the process of increasing the concentration of starch is often an ongoing process without any resting tank as in other processes. The starch water that has been separated from the cassava pulp will be passed through the separators, which can be either centrifugal separators or hydrocyclone, most factories prefer centrifugal separators. In order to get good quality cassava starch, they often use 2 sets of centrifugal separators to separate all of the cassava pulp and increase the concentration of starch.

6. Cassava starch dehydration and drying process of cassava starch production machine
The starch water will be separated from the starch using vacuum filter . The wet starch will then down into a steam pipe with hot air from the furnace. The strength of the wind will blow the starch up the chimney and  will fall into the cyclone. It takes only a short period of time to dry the starch, in order to prevent condensation of starch granules and on the other hand, to prevent decomposition of the starch as well. The hot air used in drying process is filtrated, to prevent contamination, before blowing into the steam pipe. The cassava starch received from the  cyclone is a hot, fine, dry starch, which will be immediately cooled down by a cold cyclone before being poured down the sieve,   to get equal sizes of starch. The dried starch is then sifted through a sieve before being packed into the silo. Most of the silo will be  large enough to contain the 24 hours starch production process. The packaging of the starch into bags of small factories is done  with a semi-automatic process. Meanwhile, large factories normally use an automatic system in the packing process.
