Exercise 8. Translate in the written form.

Potato starch

In Germany, The Netherlands, Poland, and a number of other countries, the extraction of the starch from potatoes is a major industry. Some factories produce over 300 tons daily. Processing involves continuous and automatic cleaning of the potatoes, thorough disintegration in raspers or hammer mills, and separation of the fibres from the pulp by centrifugal (rotary) sieves. The resulting starch "milk" contains starch in suspension and soluble potato solids in solution. The starch is separated and washed free from the solubles, the water is removed by centrifugal action, and the damp starch is dried. The flash type of dryer, using hot air, is widely employed for starches derived from both tubers and cereals.

Potato flour is also produced in Germany and other countries, slices of cleaned potatoes being dried, ground, and sieved. In Germany a "potato sago" is produced. The starch cake obtained from the potatoes is crumbled to produce reasonably uniform-size particles that are rounded by tumbling or similar operations, heated to gelatinize the outside layers of the starch, and then dried.
