Description

Germ-remaining rice processing method

Technical Field

The present invention relates to rice processing, and in particular to the processing of rice.

Background

The conventional germ-retaining rice milling mode is that materials move in a plane, the materials are positioned between a milling belt and a rice cutter, the milling belt and the rice cutter move relatively, and the materials are milled.

Since the grinding belt is a flexible material, the grinding belt between the 2 driving rollers cannot provide sufficient grinding pressure to the material. A common form of pressure support is by a platform or idler on the opposite side of the grinding belt material. The platform support may provide a uniform and continuous support force, however, friction between the grinding belt and the platform may generate relatively high temperatures. Idler support may avoid relatively high temperatures, but idlers may not provide uniform and continuous support forces.

In both CN111111814A and CN106622441B, a circular arc path milling form is adopted. When the grinding wheel (roller) is worn or the grinding pressure is adjusted, the distance between the plurality of rice knives distributed in the circular arc and the grinding wheel (roller) is changed along the radial direction, and meanwhile, the distance between the plurality of rice knives distributed in the circular arc is also changed.

The germ-remaining rice processing belongs to the field of finish processing, and small changes of the distance between rice cutters can cause the increase of broken rice rate, the reduction of germ-remaining rate and integrity, and insufficient or excessive grinding degree. And a plurality of rice knives are the grouping form, and the process of milling can have discontinuity, and a plurality of rice knives are all movable adjustable, and the rigidity and the error of the movable interface can make the stability of milling worse, are unfavorable for improving the embryo remaining rate, the integrity of embryo remaining rice. The grinding wheel (roller) continuously rotates for grinding, heat is easy to accumulate, and the generated temperature is higher.

Disclosure of Invention

The technical problem to be solved is as follows:

the grinding belt grinding type platform supports friction overheating and the supporting pressure of the carrier roller is discontinuous; the grinding form of the sand roller is not easy to dissipate heat; when the arc-shaped grinding is uniform and the diameter is changed to adjust the pressure, the properties of the grinding structural part are uniform and continuous, and the size parameters are constant.

The technical scheme is as follows:

the invention mainly comprises a milling belt, a roller and a mill.

The transmission surface of the roller is a conical surface, and 2 the side with the small diameter of the conical surface of the roller is arranged oppositely and coaxially; the transmission surface of the grinding belt is an inclined surface matched with the conical surface of the roller 2, and the transmission inclined surface of the grinding belt is sleeved on the transmission conical surface of the roller; in the area where the milling belt contacts the roller, the gap between the mill and the milling belt forms a milling chamber; the mill is fixed in position relative to the axis of the roller; the material enters the grinding cavity from one end of the grinder, and leaves the grinding cavity from the other end of the grinder after being ground in the grinding cavity; 2, the rollers are close to each other, the diameter of a grinding belt wrapping roller area is increased, the volume of a grinding cavity is reduced, and the grinding pressure is increased; the 2 rollers are far away from each other at the same time, the diameter of the area of the grinding belt covering the rollers becomes smaller, the volume of the grinding cavity becomes larger, and the grinding pressure becomes smaller.

Since the 2 rolls are required to be close to and far from each other to adjust the size of the grinding chamber, there is a non-contact condition between the end faces of the 2 rolls, and the grinding support of the grinding belt between the 2 rolls is provided only by the bulk material strength of the grinding belt. The supporting object is additionally arranged in the grinding belt, the two ends of the supporting object are always used on the conical surfaces of the 2 rollers, the supporting object has the same effect as a bridge, and the grinding supporting force of the grinding belt is increased.

Or, the small diameter end surface of the roller is provided with supporting teeth, the transmission surface of the supporting teeth is positioned in the extension surface of the roller conical surface, and the supporting teeth of 2 rollers are always crossed; the supporting teeth can always provide support for the grinding belt when the rollers are close to and far away from each other.

Has the advantages that:

the arc-shaped grinding path can design different height differences between the feeding hole and the discharging hole, so that rich grinding effect and bran removing effect are realized; the grinding pressure of the conventional flat belt is uniformly adjusted in a uniform diameter-changing mode on the circular arc grinding path; in the circular arc grinding path, the form and the position of the grinder are fixed and unchanged, and the grinding process is continuous; the milling device is easy to dissipate heat.
