Integrated extrusion molding equipment

Abstract

The invention provides integrated extrusion molding equipment, which comprises a feeding device (20), a screw extruder (10), an extrusion die (40), a rotary motor box (50), a coating device, a conveying device (70) and a cut-off device (90) in turn. The screw extruder (10) comprises a plurality of screws which are closed and occluded one another; the extrusion die (40) has two extrusion discs (41); the conveying device (70) comprises a driving roller and a conveyor belt (72) with adhesiveness; and the cut-off device (90) is arranged between the adjacent conveyor belts, and comprises a jet orifice (91) and high-pressure jet (92) emitted from the jet orifice to cut strip continuous materials (200) into sectional materials (210) with fixed lengths. The sectional treatment of the extrusion molding materials is realized through the conveying device with height fall and a high-pressure water jet system, products with specified lengths can be accurately obtained, and the cutting process is clean and safe.

Description

technical field [0001] The invention relates to an integrated extrusion molding equipment, in particular, it is an equipment for processing pre-mixed rice flour balls or dough by using a screw extruder and matching devices for extrusion, coating, cutting, etc., which belongs to food processing technology field. Background technique [0002] With the increasing requirements for food nutrition, cereal products with various complex nutrients and their production methods are also developing rapidly. From the early acid pre-steaming process, direct soaking method and coating method, etc. Up to now, it is relatively complete: from grain crushing→pretreatment→mixing with nutrients→extrusion→molding→drying→screening→rice blending in proportion, and finally obtain the technological process of nutrient-enhanced compound grains. [0003] The extrusion-forming step is an important link in the production process. Generally, a single-screw or twin-screw extruder is used to extrude the hy...

AI Technical Summary

Problems solved by technology

[0007] 1. Long strip materials need to be cut, while traditional equipment uses mechanical knives for cutting, and its accuracy and cleanliness are difficult to guarantee

[0008] 2. The screw of the traditional screw extruder is directly placed in the cavity with an oval or circular cross-section. During the re-extrusion and conveying process, the material tends to accumulate in some parts, thereby reducing the extrusion effect

[0009] 3. And because there are often accumulations in the screw cavity, these accumulations that have not been fully squeezed for a long time will condense into blocks after a period of time, which will affect the overall product output efficiency and product uniformity, and need to be cleaned frequently

However, the screw replacement process of the traditional twin-screw extruder is difficult, and after the shutdown, the screws will still produce mechanical rotation due to the interlocking structure, which is likely to cause accidents
