of extrusion (10), the fastening is carried out by means of screws (73) and respective clamping nuts that are placed through each of the matching holes (75) of the flange assembly.
Figure 8 is a perspective view of the assembly of parts of Figure 7, in its position of use when the set of flanges (71 and 72) hold and hold the distribution disk and extrusion die with the screws (73 ) in the proper tightening position; the mass is displaced by the extruder at a high temperature to maintain the proper fluidity it is necessary to maintain the temperature in a certain interval that does not allow the gelatinization of the starches and therefore hardens. For this reason it is necessary to maintain the set of flanges, distribution disk and extrusion die inside a resistance housing (81) fed through the electrical contact (82); the resistor (81) completely covers the aforementioned assembly and maintains the constant temperature within a range of 170 ° C to 200 ° C, more specifically for the preferred embodiment at the temperature of 180 °, the temperature selection will depend of the moisture content of the cereal supplied by the extruder, said cereal in the preferred embodiment is a mixture of corn, butter and other additives with a granulometry equal to 5 (five). Note that the resistance does not cover the section of the forming tubes, because in the formation zone it is required that the temperature falls so that the mass hardens and maintains the shape acquired in the former.
Figure 9 shows a view of the cutting device of the formed snack placed directly in front of the outlets defined by the flat end plate of the forming tubes; the cutting device has a drive shaft (91) provided with a fastening pin where the blade holder (94) is placed by means of the stud (95), the fastener has rectangular cuts distributed in a regular manner at a predetermined angle, in each of the cuts the seat (93) of the knife (92) is engaged which in the turning movement cuts the extruded mass that leaves the forming tubes. The drive shaft can be inclined at will to operate in a range of inclination between 80 ° and 90 °, the axis and consequently the knife rotates with a frequency of 25 to 30 Hertz to obtain a snack product of a predetermined length; specifically the turn is 26 and 28 Hertz for the preferred modalities.
