Problems solved by technology

The outlet of the discharge channel of the circular extrusion head and the small holes on the extrusion template are arranged in a circle, which will make the extruded noodles or vermicelli fall on the conveyor belt and be unevenly distributed, with more in the middle and less on both sides. Because the middle stack is too thick, it is easy to stick together, which will increase the difficulty of the subsequent anti-sticking process and the time of aging, freezing, washing and loosening, and affect the quality.

Abstract

A screw thread extruding machine comprises a screw actuating mechanism, and one or more screw mechanisms. A thread extruding cylinder is arranged outside a screw which is arranged in the cavity of the thread extruding cylinder, two ends of the thread extruding cylinder are sealed, and a shaft of the screw is arranged on sealing elements on two ends of the thread extruding cylinder. A feed inlet is arranged on the thread extruding cylinder, and the opening of the feed inlet faces upwards and is close to the end portion of the screw. The end of the screw near a discharge port is downwards provided with a thread extruding head which is provided inside with a discharging channel communicated with the cavity of the thread extruding cylinder, a thread extruding mold plate is arranged at the outlet position of the thread extruding head discharging channel, and small holes for forming bean vermicelli are opened on the thread extruding mold plate, which is characterized in that the outlet of the discharging channel is rectangular and the small holes on the thread extruding mold plate are arranged in rectangular shape. The screw thread extruding machine of the invention has the beneficial effect that the screws evenly fall on a conveyor belt and have uniform thickness on the conveyor belt, which reduces difficulty of the posterior antisticking and other techniques, shortens time of ageing effect, freezing, water scrubbing vermicelli loosing and other techniques, and enhances quality.

Description

technical field [0001] The invention relates to a screw extruder for powder slurry, dough balls or powder sheets of flour, rice flour and vermicelli. Background technique [0002] In the prior art, flour, rice vermicelli, and vermicelli are also formed by self-cooking extruders using screws, generally single-screw self-cooking extruders and twin-screw self-cooking extruders, each screw corresponds to an independent extruding head, there is a separate the discharge channel. Since the screw and the extruding cylinder installed outside the screw are circular, the discharge channel of each screw is independent, and the exit of the discharge channel of the extrusion head of the existing screw self-cooking extruder is customarily designed as a circle Shaped, the small holes on the extrusion template installed at the discharge channel of the extrusion head are arranged in a circle. The outlet of the discharge channel of the circular extrusion head and the small holes on the extru...
