Flour/bean product extrusion mechanism

Abstract

The invention relates to a flour/bean product extrusion mechanism which comprises a screw rod and a charging barrel, wherein the charging barrel is arranged outside the screw rod in a sleeving manner; the screw rod sequentially comprises a screw rod transmission joint, a feeding section, a first curing section, a second material metering curing section, a third material mixing curing section and a material extrusion buffer section; the first curing section is used for performing the first compression on the material; the second material metering curing section is used for performing the second compression on the material; the third material mixing curing section is used for performing the third compression on the material; the material extrusion buffer section is used for performing decompressed puffing on the material. The extrusion mechanism is optimized, the materials are subjected to gradient compression of the thread of the screw rod, sudden-change threaded equal-depth compression, sudden-change screw flight equal-depth compression and sudden-change equal-diameter light body compression, and screw rod rotation self-heating is combined with charging barrel exterior heating, so that the extruded flour or bean products can achieve puffing, semi-puffing, micro-puffing and non-puffing effects, and the produced foods have the characteristics of good taste, chewiness and the like. The flour/bean product extrusion mechanism belongs to the technical field of food processing machinery.

Description

technical field [0001] The invention relates to a food processing machine, in particular to an extruding mechanism for noodles or bean products. Background technique [0002] CN2798614Y discloses a food extruder. The whole machine includes a power transmission device, a speed reduction device, a screw extrusion device and a cooling device, all of which are installed on a frame; The screw extruder is equipped with a cooling device at the right end of the screw jacket of the screw extruder. [0003] The extruder with this structure can greatly improve the production efficiency, but it has the following disadvantages: 1. The material is not compressed many times, so that the output product does not have puffing or micro-puffing effect, and the output product has insufficient chewiness and Bad taste. 2. When processing noodles or bean products, due to the high pressure in the barrel, the feeding port is likely to cause unsmooth feeding, resulting in material return or material...
