The production of this kind of products is called extruding by using special machines – extruders. Grounded grains with certain stoutness are put into the extruder and then the real process begins. When the grounded grains are inside the machine so called screw conveyor under the friction pressure it gets consistency of dough which “is kneaded well enough”. This process is carried out in closed surroundings under high pressure and temperature. At the screw conveyors exits there are openings through which the hot dough is expanded, i. e. it rises several times its size. This process is identical to baking, so in this way we get the typical porous structure of the stick. After this procedure the sticks are sprinkled with vegetable oil and at the end they are powdered with seasons, which give the characteristic flavour of every product.
