Embodiment Construction

[0025] The present invention will be further described below with specific embodiment, see figure 1 -5:

[0026] A kind of starch extruder, comprises feeding double machine barrel 1 and is arranged on the feeding hopper 2 at the feed inlet place of feeding double machine barrel 1, is provided with the first screw rod 3 and the second in feeding double machine barrel 1 Two screw rods 4, the first screw rod 3 and the second screw rod 4 all have the first helical groove 5 and the second helical groove 6 of the double helix form, the helical direction of the first helical groove 5 and the second helical groove 6 is opposite, two screw rods The axes of the two screws are set in parallel, and the corresponding parts of the spiral grooves on the two screws are mirrored. One screw 3 is driven to rotate by the feeding motor 7, and the second screw 4 is driven to rotate by the transmission mechanism. The first screw 3 and the second screw 4 rotate in opposite directions. Internal rota...

Abstract

The invention belongs to the technical field of extrusion equipment, and particularly relates to a starch extruder. The starch extruder comprises a feeding double-drum and a feeding hopper, wherein afirst screw and a second screw are arranged in the feeding double-drum; each of the first screw and the second screw is equipped with a first spiral slot and a second spiral slot, which are of double-helix forms, and a spiral direction of the first spiral slot is reverse to that of the second spiral slot; spiral slots on corresponding parts of the two screws are arranged in a mirroring mode; the first screw is connected to the second screw through a transmission mechanism; the first screw is driven by the feeding motor to drive; the second screw is driven by the transmission mechanism to rotate; the first screw and the second screw oppositely rotate; a discharge machine barrel is fixedly arranged on the feeding dual-drum; a discharge mechanism is arranged in the discharge machine barrel; the feeding dual-drum communicates with the discharge machine barrel; and the discharge screw is driven by the discharge motor to rotate. According to the starch extruder disclosed by the invention, the feeding dual-screw is combined with a discharge single screw, so that performances are more stable, raw materials are guaranteed to outwards extrude continuously, and weight of extruded-out raw materials is guaranteed to be the same.

Description

Technical field: [0001] The invention belongs to the technical field of extrusion equipment, in particular to a starch extruder. Background technique: [0002] With the increasing awareness of environmental protection, people realize that the waste generated by plastic products is causing damage to the living environment of human beings. Therefore, starch-based plastics have been developed to replace plastic products. [0003] Starch tableware is a biodegradable product. It uses starch as the main raw material and is processed by high-tech production technology. It can be degraded by itself under natural conditions, avoiding environmental pollution and saving non-renewable resources such as petroleum. It has been tested by the national authoritative testing department. , all hygienic physical and chemical indicators have reached the national standard, and it is an ideal substitute for the widely used but controversial "disinfected tableware" in the catering market. [0004...
