Specific embodiment:
With specific embodiment, the invention will be further described below, referring to Fig. 1-5:
A kind of starch extruder, including feeding double machine barrel 1 and the feed hopper 2 that is arranged at the feed inlet of feeding double machine barrel 1,
The first screw rod 3 and the second screw rod 4 are provided in feeding double machine barrel 1, the first screw rod 3 and the second screw rod 4 all have Double-spiral
The hand of spiral of the first helicla flute 5 and the second helicla flute 6 of formula, the first helicla flute 5 and the second helicla flute 6 is on the contrary, two screw rods
Axis be arranged in parallel, the both ends setting of and corresponding part helicla flute mirror settings on two screw rods, two screw rods is double in feeding
It on machine barrel 1, is connected between the first screw rod 3 and the second screw rod 4 by transmission mechanism, the first screw rod 3 is turned by the driving of feeding motor 7
Dynamic, the second screw rod 4 is driven by transmission mechanism and is rotated, and the first screw rod 3,4 opposite direction rotating of the second screw rod, opposite direction rotating are meant
Refer to that the first screw rod 3, the second screw rod 4 rotate inwardly.Discharging machine barrel 8 is installed on feeding double machine barrel 1, in discharging machine barrel 8
Discharge screw 9, feeding double machine barrel 1 and discharging machine barrel 8 are provided in the first helicla flute 3 and the second helicla flute 4 of feeding twin-screw
Junction, discharge screw 9 feed end at be connected to, that is to say, that discharge port is set on feeding double machine barrel 1 respectively, is being discharged
Feed inlet is provided on machine barrel 8, discharge port and feed inlet correspond, and the discharge screw 9 is driven by discharging machine 10 and rotated,
Feeding motor 7, discharging machine 10 are controlled by controller.
First helicla flute 3 of the present invention is the structure of uniform pitch, is also possible to be made of the part of two different screw pitch,
Wherein it is less than the screw pitch of the part far from the second helicla flute 4 close to the screw pitch of the part of the second helicla flute 4.
The hand of spiral and 5 phase of the first helicla flute of first screw rod 3 of the invention, the second helicla flute 6 on the second screw rod 4
Instead, it can be ensured that starch will not carry out technology conveying on the second helicla flute 6, while can also will be delivered to the first helicla flute 5 with
The starch of second helicla flute, 6 junction is directed into setting discharge port on feeding double machine barrel 1 and enters in discharging machine barrel 8.
Further, the screw pitch of second helicla flute 6 carries out reversed increase back pressure less than the screw pitch of the first helicla flute 5.
In order to increase back pressure, the discharge screw 9 includes the identical third helicla flute 11 of the hand of spiral and the 4th helicla flute
12, the 4th helicla flute 12 is discharge end, and the screw pitch of the 4th helicla flute 12 is less than the screw pitch of third helicla flute 11.
