According to a method of production of potato pastes dough made of a mixture of wheat flour and a potato-based ingredient is extruded through delivery nozzles of an extruder head and an extruded pressing is subsequently cut, pasteurised and dried and the pressing is surface stiffened at the output from the delivery nozzles, advantageously by a stream of the gaseous drying media, which stream can be dry air. The surface stiffening is performed on a pressing with the smallest thickness a = 1.5 mm and with a circumference of the cross section with a minimum size of four times the smallest dimension "a". An equipment for execution of the method consists of a cooled extruder with a head with delivery nozzles for extruding the pressings, whereas a device for crosswise cutting of the product is attached to the front face of the head, whereas a source (7) of gaseous drying media is attached to a head (3) provided with delivery nozzles (5), whereas the source (7) is arranged for directing the gaseous drying media onto front face (4) of the head (3) of the extruder (2). |
