What steps are applied to produce the high international standards cassava starch？
Firstly to produce premium quality cassava starch, the fresh cassava roots must be healthy without rot and well handled from farm and should be processed within 24 hours after harvesting. It should be sent to a modern cassava starch processing plant that utilizes current market leading starch processing technology from manufacturers such as Henan (China) Jinrui company to ensure the highest quality product. The following cassava starch processing steps are applied to produce cassava starch that meets the high international standards of hygiene, environmental and product quality.
STEP 1. CLEANING
The fresh cassava roots will be transported by conveyor to the dry sieve. The dry sieve rotates its inner spirals to push cassava moving forward and in the process some peels of cassava roots and dirt attached on cassava roots be removed.
STEP 2. WASHING
Then the cassava will be then washed with a paddle washer with clean water to remove the residual surface mud and sand.
STEP 3. CUTTING
The cassava is transported to the cassava cutting machine that will cut it into 3 to 5cm in length. This will help relieve some pressure on the Rasping machine in the next step.
STEP 4. RASPING
At this step, the cut cassava is fed into the Rasper of Henan Jinrui company, the most modern on the market. This machine will finely crush the cassava into a high quality starch slurry.
STEP 5. EXTRACTION
The crashed starch is sent to the Henan JInrui’s Centrifugal Sieve in order to separate and purify the starch. The sieve will remove fiber and some dirt out of cassava starch slurry leaving it will with less than 0.05% fiber impurities.
STEP 6. DESANDING
Cassava starch processing steps
To improve taste sand is removed. The starch slurry is pumped into a Desander by a pressure pump. Then, according to the principle of gravity separation, the bottom stream will remove the sand while starch slurry flows through the top to achieve the purpose of sand removal.
STEP 7. REFINING
This step is to wash, concentrate and refine the starch slurry. The cassava starch slurry will be passed into the Jinrui’s Hydrocyclone in order to use centrifugal force to separate the protein and cell liquid out of the slurry, and wash and concentrate. The result is a pure white Cassava Starch Milk.
STEP 8. DEWATERING
In preparation for drying, the Cassava Starch Milk is dewatered to achieve a water content of less than 40%. The starch milk is passed into the Henan Jinrui’s peeler centrifuge that is specifically designed for dewatering starch slurry and to meet the high hygienic standards of today.
STEP 9. DRYING
The final step is to dry the starch to international standards. The starch will be piped into the Henan Jinrui’s Flash Dryer where it will mix with heated high speed fresh air to a required moisture content 10% – 14% to produce premium quality Cassava Flour.
STEP 10. PACKING
Cassava starch will be packed by automatic packing machine. Pack desired quantities of cassava starch in polythene bags, seal or stitch as appropriate.
To sum up, cassava starch processing steps of above can help you to obtain the high international standards cassava starch. And all of these modern cassava starch processing machines can be customize from Henan China JInrui company’ s own factory and technology team. If you need it, welcome to leave message to us. You should sent us your capacity or budget of other specific requirements.
