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 2 grinding actuating units, wherein each grinding actuating unit comprises a roller, a grinding belt and a supporting platform. The grinding belt is sleeved on the roller, and the supporting platform supports the grinding belt from inside to outside; the support platform is provided with flanges on both sides for limiting movement of the grinding belt relative to the roller in the direction of the roller axis.

2 grinding actuating units, one below and the other above; the supporting platform in the lower grinding application unit supports the upper grinding belt from inside to top, the supporting platform in the upper grinding application unit supports the lower grinding belt from inside to bottom, the positions of the supporting platforms in the upper and lower grinding application units correspond, and gaps between the grinding belts at the supporting platforms in the upper and lower grinding application units form a grinding cavity.

The rollers in the upper and lower grinding actuating units rotate in the same direction, the rollers drive the grinding belts to move, and the movement directions of the grinding belts on the upper side and the lower side of the grinding cavity are opposite in the length direction of the grinding belts; at the same time, the upper grinding actuating unit reciprocates relative to the lower grinding actuating unit in the axial direction of the rollers in the lower grinding actuating unit.

The brown rice enters the grinding cavity from one end of the grinding cavity and moves towards the other end of the grinding cavity. Because the surface of the brown rice is not a standard cylindrical surface, the roller rotates to drive the grinding belt to move, and meanwhile, the grinding actuating unit above moves back and forth relative to the grinding actuating unit below along the axial direction of the roller, so that the brown rice can do composite rotary motion around the long axis and the short axis of the brown rice. When the brown rice is in compound rotation movement, the radial space size of the grinding cavity is smaller than the long axis size of the brown rice, so the brown rice cannot turn over in the long axis direction.

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 realize different grinding effects, the size of the grinding cavity is set to be adjustable; the upper grinding actuating unit is at an angle to the axis direction of the rollers in the lower grinding actuating unit relative to the direction of the reciprocating movement of the lower grinding actuating unit.

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 2 grinding actuating units 1. As shown in fig. 2, the milling actuator unit 1 includes a roller 1-1, a milling belt 1-2, and a support platform 1-3. The grinding belt 1-2 is sleeved on the roller 1-1, and the supporting platform 1-3 supports the grinding belt 1-2 from inside to outside; as shown in fig. 2, the supporting platform 1-3 is provided with flanges 1-3-1 on both sides for limiting the movement of the milling belt 1-2 relative to the roll 1-1 in the direction of the axis of the roll 1-1.

As shown in fig. 1, one grinding actuator unit 1 is at the bottom and the other grinding actuator unit 1 is at the top; the supporting platforms 1-3 in the lower grinding executing unit 1 support the upper side grinding belt 1-2 from inside to top, the supporting platforms 1-3 in the upper grinding executing unit 1 support the lower side grinding belt 1-2 from inside to bottom, the positions of the supporting platforms 1-3 in the upper and lower grinding executing units 1 correspond, and the gap between the grinding belts 1-2 at the supporting platforms 1-3 in the upper and lower grinding executing units 1 forms a grinding cavity 2.

As shown in figure 1, the rollers 1-1 in the upper and lower grinding actuating units 1 rotate in the same direction, the rollers 1-1 drive the grinding belts 1-2 to move, and the upper side and the lower side of the grinding cavity 2 at the position of the grinding cavity 1 move in opposite directions in the length direction of the grinding belts 1-2; at the same time, the upper grinding executing unit 1 reciprocates relative to the lower grinding executing unit 1 in the axial direction of the roller 1-1 in the lower grinding executing unit 1.

The brown rice enters the milling chamber 2 from one end of the milling chamber 2 and moves toward the other end of the milling chamber 2. Since the surface of the brown rice is not a standard cylindrical surface, the roller 1-1 rotates to drive the milling belt 1-2 to move, and meanwhile, the upper milling actuator unit 1 reciprocates relative to the lower milling actuator unit 1 along the axial direction of the roller 1-1, so that the brown rice can do compound rotation motion around the long axis and the short axis of the brown rice, as shown in fig. 3. When the brown rice is in the composite rotating motion, the radial space size of the milling cavity 2 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 2, 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 support platform 1-3 is arranged to be adjustable in the normal direction of the milling belt 1-2, in such a way that the size of the milling chamber 2 is changed, and different milling effects are achieved.

Third embodiment

As shown in fig. 6, the upper grinding actuating unit 1 is at an angle to the axial direction of the rollers 1-1 in the lower grinding actuating unit 1 with respect to the direction of the reciprocating movement of the lower grinding actuating unit 1.
