How to extract tapioca from cassava?

Here are the detail steps of how to extract tapioca from cassava
1. Cassava transportion and weighting: Cassava roots have 24-48 hours shelf-life after harvest, so the roots have to be processed within 2 to 3 days from harvest. Therefore the newly harvested cassava should be transpoprted into factory for processing as soon as possible. Then the cassava is weighted and prepares for how to extract tapioca from cassava.

2. Cleaning: The weighted cassava is transported in dry sieve by conveyor to remove the sand, weed, stones and other debris. There is no water needed in this process for how to extract tapioca from cassava. The dry sieve is designed with multi spirals which push cassava forward during the cleaning process.  

3.Washing:Then it goes into the paddle washing machine to further wash the attached silt, grave and other impurities for how to extract tapioca from cassava. Water is needed for this process. And the machine adopts countflow washing method to improve washing effect.

4. Crushing: The washed cassava is then transported into crushing machine by screw feeder. This is the vital process for how to extract tapioca from cassava. The purpose of this process is to  crush cassava into starch so as to releasse starch from cell wall. The breakage rate and extraction rate of the machine determines the final cassava starch yield. DOING rasper is a high efficient machine with a breakage rate more than 94%.

5. Separating: The grinded cassava slurry then enters into centrifuge sieve for separating fiber and starch. The centrifuge sieve takes use of high speed centrifugal force to separate the fiber with starch. For the process of how to extract tapioca from cassava, we usually take multi centrifuge sieve for a better separating effect.

6. Desanding: This process is mainly for remove the sand content out of cassava slurry for it has a bad influence on the taste of cassava starch for how to extract tapioca from cassava. The desander utilizes the different specific gravity between the cassava starch and sand to remove the sand in cassava starch production line.

7. Concentration and refining: After desanding, the cassava starch enters into hydrocyclone station for how to extract tapioca from cassava.

8. Dewatering: The widely used cassava starch processing machine for the dewatering process for how to extract tapioca from cassava is peeler centrifuge whose main function is to reduce the water content of starch milk. It is required that the moisture content of starch milk is about 38% after dewatering.

9. Drying and packing: Flash dryer takes use of the high speed hot air to dry cassava starch which is completed just in a few seconds. The whole system is under negative pressure, no dust and energy saving. The moisture content of starch after drying is between 12 and 14%, reaching the standard of finished products. And the starch is packed by automatic packing machine. The whole process for how to extract tapioca from cassava is completed.
