Reconstituted rice preparation plant

Abstract

The invention discloses a reconstituted rice preparation plant. Along the material flow direction, the reconstituted rice preparation plant orderly comprises a dust-removal system, a pulverizing system, a premixing system, a multiway mixing system, an extrusion molding system, a predrying system, a tower type drying system, a box-type drying system and a color selection system, wherein the premixing system is a staggered combined type mixing reaction kettle, and the multiway mixing system is a horizontal three-chamber multiway mixing device; the extrusion molding system is a screw extruder and is provided with 2-4 multisection temperature-control heating type screws which mesh with each other and can rotate in reverse directions, and each screw is provided with at least 2 connecting sections, at least 2 thermal insulation sections, at least 1 first mixing section, at least 1 second mixing section, at least 1 third mixing section and a discharge section; the predrying system is a drier with multiple dispersion structures; the tower type drying system is a drying tower with a forward-backward distribution structure; and the box-type drying system is a multistage drier with gas agitation function.

Description

technical field [0001] The invention relates to a reconstituted rice preparation device, in particular to a multifunctional and integrated reconstituted rice preparation device, which belongs to the field of mechanical equipment. Background technique [0002] In the process of preparing and processing reconstituted rice, several procedures such as dust removal, pulverization, mixing, extrusion, cutting and forming, drying, and inspection are required. However, the existing devices used for each procedure have various technical defects, and now There is no integrated device designed to match each other, which can carry out the above steps, and can be used for the preparation of reconstituted rice. [0003] During the processing of reconstituted rice, the solid powder of grains and liquids such as water need to be uniformly mixed to obtain a solid-liquid mixture with high viscosity, and various solid and / or liquid additives need to be further uniformly added to the above-menti...

AI Technical Summary

Problems solved by technology

[0017] 1. The screw of the traditional twin-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

[0018] 2. 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

Although the powder and granular materials are divided into several groups, which can promote the uniform drying of the materials, the bonding between the material particles and the uniform drying of the interior and surface of the materials cannot be avoided.
