Detailed Description

As shown in fig. 1, a peanut shelling device according to an embodiment of the present invention comprises: the roller mechanism 1 comprises an outer roller body 2 rotating anticlockwise and a static inner roller body 5, and connecting roller edges 3 on two sides of the outer roller body 2 prevent peanuts from going outwards. The flat conveying mechanism 7 comprises a flat conveying vibrator 8 and a flat conveying plate 9 which provide power, and guard plates 10 are additionally arranged on two sides of the flat conveying plate 9. The flat conveying mechanism 7 is arranged below the discharging slideway, a blanking hole 21 is machined on one section of the flat conveying plate 9, the conveying belt 11 is arranged below the blanking hole 21, and the two sides of the conveying belt 11 are provided with the baffle plates 12. Conveying peanuts and fine peanut shells falling from the blanking hole 21 to a rear fan for separation; the turntable mechanism 14 includes a turntable 18 that is driven by a motor. A turntable mechanism 14 is mounted below the leveling plate 9. The upper surface of the rotary disc 18 is coated with edible silica gel, and the outer edge of the rotary disc 18 is provided with a coaming 17. The section of the blanking guide plate 16 is in an embedded shape, an included angle is formed between the section and the diameter of the rotary disc 18, the blanking guide plate 16 is made of a material with certain plasticity, and the bottom of the blanking guide plate is in contact with the rotary disc 18. The gap between the milling roller 15 and the turntable 18 is adjustable.

As shown in fig. 2, the centers of the outer cylinder 2 and the inner cylinder 5 are on a horizontal plane, and an eccentricity exists between the centers, and the eccentricity can be adjusted, so that the gap at the left side feed inlet is larger than the gap at the right side discharge outlet. The feeding slideway 4 enters from the outside to the inside of the roller mechanism according to a certain inclination, and the lower outlet of the feeding slideway 4 is arranged at the feeding port at the left side of the roller mechanism 1; the discharging slideway 6 is arranged from the inside to the outside of the roller mechanism 1 according to a certain inclination, and the upper inlet of the discharging slideway 6 is arranged at the right discharging port of the roller mechanism 1. The cross section of the outlet of the feeding slideway 4 is quadrilateral, which is convenient for the peanut blanking. The inner cylinder 5 is in a half cylinder shape, a front chamfer 19 is processed on the feeding side of the inner cylinder 5, and a rear chamfer 20 is processed on the discharging side of the inner cylinder 5.

As shown in fig. 3, a blanking hole 21 is processed in the leveling plate 9.

As shown in fig. 4, a fan 13 is installed at the end of the conveyor belt.

As shown in fig. 5, the crushing roller 15 and the blanking guide plate 16 are mounted above the turntable 18.

As shown in fig. 6, the inner wall of the outer cylinder 2 is grooved in the axial direction.

An eccentric distance exists between the outer cylinder body and the center of the inner cylinder body, and the eccentric distance can be adjusted, so that the gap at the left side feeding port is larger than the gap at the right side discharging port, and the peanuts are gradually extruded to break the shells. Most of the peanuts fall off from the feed holes by utilizing the sieving principle of the horizontal conveying mechanism. Through the rolling of the turntable mechanism, the peanuts are subjected to secondary shell breaking and separation, so that the meat yield of the peanuts is improved. The inner wall of the outer cylinder body is provided with a groove along the axial direction, the upper surface of the turntable is coated with edible silica gel, and the friction force between the mechanical surface and the peanuts is added through the improvement of the process, so that the peanut shell breaking rate is improved.

In particular use, the invention will be described separately with reference to the accompanying drawings for the convenience of understanding;

1. in the roller shelling process, (see fig. 1, 2 and 6), when peanuts with shells enter the roller mechanism through a feeding slideway, the peanuts with the shells move along the clearance between the inner roller and the outer roller along the anticlockwise direction from a feeding port on the left, and the peanuts on two sides are blocked by the roller edges; meanwhile, the peanuts are squeezed and the peanuts and the inner and outer cylinder walls are squeezed, so that the peanut shells are broken. And the peanut kernels and the peanut shells continue to move to reach the discharge track through the discharge port.

2. In the sieving separation process (see fig. 1 and 3), the peanut and peanut shell are taken to the horizontal conveying plate of the horizontal conveying mechanism by the discharging track through a certain inclination, the peanut and peanut shell move from left to right while sieving through the operation of the horizontal conveying vibrator, when the peanut and peanut shell reach the discharging hole of the horizontal conveying plate, most of the peanut and the peanut shell with the diameter smaller than that of the discharging hole fall down to the conveying belt through the discharging hole due to the fact that the diameter of the discharging hole is slightly larger than that of the peanut, and the peanut shell and the small part of the peanut shell enter the rotary table mechanism.

3. In the process of separating the peanuts from the peanut shells (see fig. 4), the conveying belt conveys the peanuts and the peanut shells to the tail end and falls down, and the wind of the fan blows the peanut shells with lighter specific gravity away to leave the peanuts.

4. In the grinding process (see fig. 5), after the peanut shells and a small part of peanuts enter the turntable mechanism, edible silica gel is coated on the upper surface of the turntable, so that the friction force between the mechanical surface and the peanuts is increased, the peanut shells and a small part of the peanuts rotate along with the turntable to reach the lower part of the grinding roller, and the gap between the grinding roller and the turntable is adjusted to be slightly larger than the diameter of the peanuts, so that the peanut shells and the peanuts are subjected to secondary shell breaking and separation. The peanut shells and the peanuts leave the rotating disc and enter the second sieving separation step and the peanut and peanut shell separation step (the process is consistent with the steps 2 and 3) under the guiding action of the feeding guide plate. The meat yield of the peanuts is improved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
