Tapioca is an important tuber crop cultivated in many tropical countries of the world.

Peeling & Washing: of the tubers to remove and separate all adhering soil and as much protective epidermis as necessary.

Rasping or Pulping: to destroy the cellular structure and to rupture the cell walls to release the starch as discrete, undamaged granules from other insoluble matter.

Screening or extraction to separate comminuted pulp into two fractions, viz. waste fibrous material and starch milk.

Dewatering: or purification to separate the solid starch granules from their suspension in water by sedimentation or centrifuging.

Drying: to remove sufficient moisture from the damp starch cake obtained during the separation stage so as to reduce the moisture content to a level low enough for long term storage.

Pulverization & Dry Screening: Crude dry tapioca flour consists of hard lumps of starch. As it cannot to be used as such, it has to be subjected to a pulverizing process followed by dry-screening. Roller crushers can be employed for pulverizing and a sieve size of 100 to 200 mesh is used for screening. It is finally Packed in jute bags.
