Combined type rice milling machine

Abstract

The invention discloses a combined type rice milling machine. The combined type rice milling machine comprises a shell and a vertical type rice milling chamber formed in the shell, wherein the rice milling chamber comprises a rice milling roll and a sieving plate; the sieving plate is divided into a three-step structure, and the inner diameters of inner-layer sieving nets of the three-step structure are increased in sequence on different steps from top to bottom, and simultaneously inclined transition surfaces with leaking sieves are also arranged on junction surfaces of different steps; and the rice milling roll is sheathed on a main shaft and is connected with a driving motor by the main shaft; the two ends of the rice milling roll are respectively provided with a feeding shaft bearing seat and a discharging shaft bearing seat, and the parts of the feeding shaft bearing seat and the discharging shaft bearing seat, which extend into the inner-layer sieving nets, form the rice milling chamber together with the inner-layer sieving nets, and the size and the structure of the rice milling roll at the part are matched with the structures and the sizes of the inner-layer sieving nets, and a 20-30mm processing gap is left between the rice milling roll and the sieving plate. The combined type rice milling machine disclosed by the invention has the advantages that multiple operations of impurity removal, polishing and whitening for rice to be processed can be realized, simultaneously the whitening efficiency is high, the rate of broken rice is low and the equipment is durable.

Description

technical field [0001] The invention relates to the technical field of grain screening and processing, in particular to a combined rice mill integrating impurity removal, rice milling, polishing and grading. Background technique [0002] With the improvement of industrial modernization, more and more industries have begun to realize mechanized mass production. Among them, among the processing machinery in the rice processing industry, rice milling equipment, as an important part of the rice processing production line, is mainly used to whiten brown rice into white rice. Its working method is similar: brown rice enters the rice mill from the feed port, After being sent into the rice milling chamber composed of rice milling rollers and sieve plates under the action of screw propeller or other flow regulating mechanism, through the action of internal pressure, the rotation of iron roller or emery roller, and the action of fan blowing wind, the rice grains and Between the rice ...

Problems solved by technology

However, whether it is a small, medium or large rice mill, it is mainly composed of a feeding device, a rice milling room, a discharge device, a transmission device, a blowing system, etc., and the structural setting of the rice milling room directly affects the rice milling machine. work efficiency and rice milling quality, and the design of the rice milling room of the existing rice mill is too simple, which makes its function single, and mostly uses emery rollers for milling, which cannot meet the needs of continuous production. To a certain extent, there are also the defects that the rice output rate is low and the quality of the rice output is difficult to control.
