Problems solved by technology

And in actual production, when processing low-oil crops, due to the low oil content of low-oil crops, the existing equipment, the thrust of the material from the puffing chamber to the discharge port is relatively large, and the impact on the pressure ring is also very large. This kind of production appears The loosening and falling off of the pressure ring leads to more frequent loosening or even falling off of the fastening structural parts

Abstract

The invention discloses an improved puffing machine. The puffing machine includes an puffing chamber and a conditioner: a main shaft and a screw are arranged in the puffing chamber along its length direction, and a spiral protrusion is provided on the outer wall of the screw; The conditioner is provided with a feeder, and the feeder is provided with a feeding auger: the end of the main shaft is provided with a bolt, and the bolt extends out of the port of the main shaft discharge port, and the outer part of the bolt is The end is in a structure that fits with the nut, and the nut covers the end of the bolt and the end of the screw to the position close to the second gasket; the longitudinal section of the spiral protrusion is a trapezoidal structure: the trapezoidal structure is a right-angled trapezoid Or approximately right-angled trapezoidal structure; the spacing of the feeding augers is not equal. The use of the extruder is not limited by the pressure ring, and the pressure adjustment range is larger.

Description

technical field [0001] The present invention relates to an improved puffing machine. Background technique [0002] Material puffing requires pressure, if the pressure is not up to the requirement, the degree of extrusion of the material will not be enough, and the puffing of the material will not be complete, which will affect the degree of ripening and puffing. In existing extruders, the change of pressure can be realized by adjusting the screw gap, screw speed, pressure ring and the gap between the expansion chamber. On the basis of fixing the screw gap, screw speed and the gap between the expansion chamber, it is basically realized by installing the pressure ring. The pressure ring installed on the extruder head part is impacted by the huge thrust generated by the material moving from the puffing chamber to the discharge port, which may easily lead to loosening and falling off, further affecting the original fastening structural parts. Take the TDPH-260 raw material puffi...
