Cassava starch production process instruction

The cassava starch production process basic principle: The cassava starch production process actually is a physical separate process, to separate the starch from fiber, protein, inorganic substance and others. During the production, Doing Company use special machinery seperate the starch from water suspension, to complete the cassava starch production process. To separate starch from cassava, firstly you must crush the cassava to make the starch free from cassava, then we can get a cassava starch slurry, next washing and sieveing the starch slurry to get clean starch milk, then process the starch milk to get final starch. The total cassava starch production process is cassava cleaning-cassava crushing-seperating-concentration-refining-dewatering-drying-sieving and packing.

Next is the details of cassava starch production process: Step 1 cassava cleaning Cassava will be transported by conveyer to dry sieve. Then dry sieve rotates its inner spirals to push cassava moving forward. In the process, some peels and dirt things of cassava will be cleaned. Step 2 cassava washing Next, cassava paddle washing machine will rotate its paddle, then cassava which are flow in the counter water current will be cleaned. This is the cleaning step of the production of cassava starch. This two section cleaning process in cassava starch production process can guarantee the cassava cleaning get a good effect, important for starch quality.

Step 3 cassava cutting The clean cassava will be transported to cassava cutting machine. The machine will cut cassava into 3-5cm pieces. It consists of foundation, main frame, cutter, motor and drive system. The step can relieve some pressure of the next machine, also can help to make the starch fully free in the cassava starch production process.

Step 4 cassava crushing For the cassava starch production process, cassava which have been cutted by cutting machine will be fine crushed by rasper. The machine has a high extraction rate. It is a bidirectional rasper, which cause high efficiency of the production of cassava starch. The machine can crush cassava into a kind of starch slurry.

Step 5 cassava starch slurry sieving Centrifugal sieve and fine fiber sieve will be used to remove fiber, cell liquid and some dirt out of cassava starch slurry. The two machines have large capacity and all have automatic front and back washing system, which guarantee good operation and ensure high-efficiency operation of equipment in cassava starch production process.

Step 6 concentration and refining: Adopt disc separator and hydrocyclone combined to complete this step is high efficiency. Disc seperator use centrifugal force to accelerate separating process and separate protein and cell liquid out of slurry. It can be used for enrichment and purification of starch slurry. Then hydrocyclone station is used to washing and concentrating scrubbing starch milk. After this, we can get a clean starch milk of cassava starch production process.

Step 7 cassava starch dewatering Then peeler centrifuge is used to dehydrate cassava starch slurry. It is a solid-liquid separation equipment. The machine can shorten separating time and increase production capacity by 50%.

Step 8 cassava starch drying Cassava starch will be dried by air-flow flash dryer. The machine adopts negative system and cooling system, so the drying time is very short. In order to guarantee the production of cassava starch, air flow flash dryer should be operated in advance.

Step 9 cassava starch sieving and packing After drying, cassava starch will be sieved by cassava starch sieving machine, soonly cassava starch will be packed by automatic starch packing machine.

In conclusion, this is the whole cassava starch production process introduction. Cassava starch has a promising market. Cassava starch production process effect decided the using rate of cassava and the final cassava starch total capacity. And Doing Company cassava starch production process can guarantee the starch extraction rate more than 94%. Cassava roots size is very different large and small, starch content is very high, but protein, fat, gray content is small, especially in fresh cassava, its starch content is 25%-32%, so cassava is a good raw material to extract starch.
