Description

Milling device

Technical Field

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

Background

After the brown rice is processed into embryo-remaining rice by the roller and the circular arc-shaped grinding blade group or the grinding belt and the plane grinding blade group, although the embryo-remaining rate and the embryo-remaining degree of the product are higher, the embryo-remaining rate and the embryo-remaining degree are higher, the grain loss is further reduced, and a large space is still left.

Disclosure of Invention

The technical problem to be solved is as follows:

the broken rice rate of the remained embryo rice is reduced, and the embryo remaining rate and the embryo remaining degree of the remained embryo rice are improved.

The technical scheme is as follows:

the invention comprises a roller, a milling belt, a milling plate supporting seat, a circular arc milling plate and a milling cavity. Flanges are arranged at two ends of the roller, the grinding belt is sleeved on the roller, and the flanges limit the grinding belt to move along the axial direction of the roller. The inner side surface of the circular arc-shaped grinding plate is a circular arc-shaped cylindrical surface, the axis of the circular arc-shaped grinding plate is coincided with the axis of the roller, and the outer side surface of the circular arc-shaped grinding plate is fixed with the grinding plate supporting seat. The gap between the inner side surface of the circular arc-shaped grinding plate and the grinding belt forms a grinding cavity.

The roller rotates around its axis, the portion of the milling belt in contact with the roller makes a circular motion, and simultaneously, the circular arc-shaped milling plate and the milling plate supporting seat reciprocate along the axis of the roller.

The milled brown rice moves from one end of the milling cavity to the other end of the milling cavity around the axis of the roller in the milling cavity, and the circular arc-shaped milling plate reciprocates along the axis of the roller simultaneously, so that the brown rice performs compound rotary motion around the long axis and the short axis of the brown rice. Since the radial spatial dimension of the milling chamber is smaller than the major axis dimension of the brown rice, the brown rice is not turned in the major axis direction thereof.

Under the motion state of the brown rice, the pure friction type grinding of the surface of the single brown rice can be realized.

In order to ensure that the brown rice can not be subjected to rigid acting force and impact when moving in the milling cavity, the broken rice rate is obviously reduced, the embryo remaining rate and the embryo remaining degree are improved, and the circular arc milling plate is made into elastic rubber.

Has the advantages that:

the structure is simple and ingenious. The yield of the product is high, and the loss of grains is reduced. The embryo remaining rate and the embryo remaining degree of the embryo remaining rice can be obviously improved.

Detailed Description

In order to express the invention more concisely and comprehensively, the following embodiments are preferred:

implementation mode one

As shown in fig. 1, the present embodiment includes a roller 1, a milling belt 2, a milling plate support base 3, a circular arc-shaped milling plate 4, and a milling chamber 5. As shown in figure 2, two ends of the roller 1 are provided with flanges 1-1, the grinding belt 2 is sleeved on the roller 1, and the flanges 1-1 limit the movement of the grinding belt 2 along the axial direction of the roller 1. The inner side surface of the circular arc-shaped grinding plate 4 is a circular arc-shaped cylindrical surface, the axis of the circular arc-shaped grinding plate 4 is coincided with the axis of the roller 1, and the outer side surface of the circular arc-shaped grinding plate 4 is fixed with the grinding plate supporting seat 3. The gap between the inner side surface of the circular arc-shaped grinding plate 4 and the grinding belt 2 forms a grinding cavity 5.

As shown in fig. 1, the roller 1 is rotated in the direction of the arrow, and the portion of the milling belt 2 in contact with the roller makes a circular motion, while the circular arc-shaped milling plate 4 reciprocates along the axis of the roller 1 together with the milling plate support base 3. The brown rice enters the milling chamber 5 from one end of the milling chamber 5 and within the milling chamber 5 the milling belt 2 moves the brown rice about the axis of the roller 1 towards the other end of the milling chamber 5. As the surface of the brown rice is not a standard cylindrical surface, as shown in figure 3, the roller 1 rotates to drive the grinding belt 2 to move, the circular arc grinding plate 4 simultaneously reciprocates along the axis of the roller 1, and the brown rice can do compound rotary motion around the long axis and the short axis of the brown rice. When the brown rice is in the composite rotating motion, the radial space size of the milling cavity 5 is smaller than the long axis size of the brown rice, so that the brown rice cannot turn over in the long axis direction, the brown rice can be repeatedly switched to the motion state shown in fig. 4 in the milling cavity 5, and the brown rice is moderately milled.

Under the motion state of the brown rice, the pure friction type milling of the surface of the single brown rice can be realized, the broken rice rate of the product is obviously reduced, and the embryo remaining rate and the embryo remaining degree are obviously improved.

Second embodiment

The circular arc-shaped grinding plate 4 in the first embodiment is made of rubber, and the rubber has elasticity and the same property on the circular arc-shaped cylindrical surface, so that each piece of brown rice can be subjected to sufficient grinding pressure. The hardness of the rubber is less than that of the brown rice, when the brown rice moves in the grinding cavity 5, the brown rice cannot be subjected to rigid acting force and impact, the broken rice rate of the product is obviously reduced, and the embryo remaining rate and the embryo remaining degree are obviously improved.
