As shown in Figure 2, the double screw extruder of the embodiment of the invention comprises and mixes transportation section A, mixes the section of pinching B and push transportation section C.
Mixing transportation section A is used for mixing and convey materials.
Material is mixed by various ingredients usually, and in a preferred implementing process, material for example comprises the mixture of the high temperature dregs of rice, corn gluten protein and water.Wherein, the high temperature dregs of rice can be high temperature dregs of beans or the high temperature peanut meals that is rich in high temperature albumen, and corn gluten protein is used for improving the protein content of material, preferably adopt Gluten, but the present invention is not restricted to this.
After material got into and mixes transportation section A, under the turning effort of A section screw rod, the flight on the screw rod stirred material, makes material mix as far as possible.Simultaneously, under the effect of flight, material is fed forward along the space spiral between the flight.
Mix transportation section A and preferably form, have the first pitch S by the screw element building block system
A=30mm～276mm, first draw ratio (ratio of A section total length and screw diameter) L
ABe 6～64, preferably be arranged between the 32-64.In addition, the screw diameter of A section is φ 30mm～φ 276mm, helical pitch (helical pitch equals 2 times of pitch) P=60mm～552mm, and sleeve diameter is 8～200mm.Usually, screw diameter is big more, and sleeve diameter also can increase accordingly.
The operating temperature of mixing transportation section A is arranged in about 20 ℃～160 ℃ scopes usually, preferably is set to 100 degree, thereby realizes better mixed effect.The temperature of this section can be through heater on the corresponding sleeve and cooling device control.
Mix the section of pinching B be used for to material push, broken and kneading.

C=7.5mm～276mm, the 3rd draw ratio L
CBe 1～60.In addition, the screw diameter D=30mm～276mm of C section, helical pitch P=60mm～552mm.
According to the difference of material situation (material mixture ratio, viscosity etc.), the 3rd pitch S of extruding transportation section C
CCan be set to greater than, be equal to or less than the pitch of mixing the section of pinching.The pitch of extruding transportation section is bigger than normal, convey materials that can be more stable, but the wire drawing state of material is undesirable; Pitch is less than normal, and the wire drawing state of material is more satisfactory, but mass transport speed less stable.In a preferred embodiment, the 3rd pitch S
CPreferably be set to less than or be approximately equal to the second pitch S
B, but the present invention is not restricted to this.C section pitch is littler, in screw, can produce bigger extruding force to material, thereby more fully material pushed and kneads, and makes the silk-like proteins in the material closelyr bonding, thereby is convenient to carry than even velocity.
The 3rd draw ratio L
CPreferably be set to less than the second draw ratio L
B, it is extruding and convey materials that the C section mainly acts on, and is purpose than even velocity material is steadily transferred out double screw extruder, does not therefore need long operating distance.
The temperature of extruding transportation section C is controlled in 80 ℃～250 ℃ scopes, preferably is set to be equal to or less than the temperature of mixing the section of pinching B.In a preferred embodiment, for example be set to 100 ℃, but the present invention is not restricted to this,, also can be set to be higher than B section temperature according to the different component and the proportioning of material.
The draw ratio of the double screw extruder of present embodiment preferably is arranged between the 28-64.For example, according to the difference of practical situations, can be set to numerical value such as 28,32,40,48,51,60.
As stated, extruding transportation section C applies bigger extruding force, for example 5～12.5kg/cm through screw action to material
2Extruding force, evenly fine and close more with the material extruding in short operating distance transfers out double screw extruder with speed stably.Can promote the bonding between the material protein molecular thus, form more filamentary fibers, further increase the length of filamentary fibers, thereby promote the quality of wire-drawing protein.
Like this, through the sequential processes of mixing transportation section A, mixing the section of pinching B and extruding transportation section C, material finally forms the filamentary fibers form, promptly begins to take shape wire-drawing protein.
