Description

Technical Field

[0001] The present application relates to the technical field of macadamia nut processing equipment, and in particular to a macadamia nut degreening device. Background Art

[0002] Macadamia nuts, also known as macadamia nuts, are native to Australia. In recent years, with the expansion of my country's planting scale, my country's macadamia nut production has been increasing year by year. For this reason, the automated processing equipment for macadamia nuts has also been continuously upgraded. After being picked, macadamia nuts need to go through multiple processes such as grading, cleaning, de-greening, drying, and seasoning. The de-greening process mainly removes the thin green skin on the outside of macadamia nuts to prevent the nuts from mold and deterioration, and also facilitates the subsequent shelling and drying steps. The green skin of macadamia nuts is brittle and can be broken by squeezing. For example, a nut peeling device disclosed in Chinese patent application number 202221187461.0 includes a frame, a peeling box, a screw rod, a motor, a mounting seat, an elastic support assembly, and a chain plate. The two screw rods are rotated to squeeze the macadamia nuts so that the green skin of the macadamia nuts is broken and separated from the nuts, thereby achieving the purpose of peeling. However, the rotation speed of the screw rod is limited and the processing speed is low. Therefore, a macadamia nut peeling device is needed, which crushes the macadamia nuts through a lower pressure roller to break the green skin of the macadamia nuts to achieve the purpose of peeling. The equipment has a fast processing speed and can improve the processing efficiency of the peeling process. Utility Model Content

[0003] In order to solve the above problems, the present application proposes a macadamia nut degreening device, which crushes the macadamia nuts through a lower pressure roller to crack the green skin of the macadamia nuts, thereby achieving the purpose of degreening.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0018] like Figure 1 to Figure 2 As shown, an embodiment of the utility model provides a macadamia nut degreening device, comprising: a plate chain conveyor 1, a lower pressure roller 2, a support frame 3, and a slider 4. The plate chain conveyor 1 is installed on the ground, and the plate chain conveyor 1 comprises a plate chain 5 and a frame 6. The plate chain 5 is installed on the frame 6, and the support frame 3 is installed on both sides of the frame 6. A guide protrusion 7 is provided on the inner side of the support frame 3. The slider 4 is installed on the inner side of the support frame 3 through the guide protrusion 7, and the slider 4 is slidably connected to the support frame 3. Both ends of the lower pressure roller 2 are connected to the slider 4 through a rotating shaft 8, and the rotating shaft 8 is perpendicular to the movement direction of the plate chain 5.

[0019] Before the fresh macadamia nuts are de-greened, they need to be graded. After the grading, the particle sizes of the fresh macadamia nuts are close, so that they can be de-greened. When de-greening, the fresh macadamia nuts are fed into one end of the plate chain conveyor 1 by the feeding equipment. The plate chain conveyor 1 is driven by the motor to drive the plate chain 5 to move. The fresh macadamia nuts are driven by the plate chain 5 to enter under the lower pressing roller 2. Under the push of the anti-slip strip 9 on the plate chain 5, the fresh macadamia nuts pass through the gap between the lower pressing roller 2 and the plate chain 5. When passing through, the fresh macadamia nuts are squeezed by the lower pressing roller 2 and the plate chain 5, so that the green skin of the fresh macadamia nuts is compressed. At the same time, the lower pressing roller 2 is passively rotated by the friction force of the fresh macadamia nuts. Therefore, the lower pressing roller 2 can rub the broken green skin to separate the green skin from the wooden shell of the macadamia nuts. After repeated rolling by multiple lower pressing rollers 2, the green skin is removed from the fresh macadamia nuts. The green skin can be further separated by flotation or air selection in the later stage. The plate chain conveyor 1 has a high conveying capacity, and the method of crushing and breaking the skin is simple and fast, which greatly improves the efficiency of de-greening, and the processing efficiency of the equipment is high.

[0020] The plate chain conveyor 1 uses a hard plate chain 5 for conveying, and has a high load-bearing capacity, so that the plate chain 5 can provide sufficient supporting force to crush the green peel.

[0021] In a preferred embodiment, a plurality of anti-slip strips 9 are provided on the plate chain 5, the long direction of the anti-slip strips 9 is perpendicular to the movement direction of the plate chain 5, and the material of the anti-slip strips 9 is rubber. The raised anti-slip strips 9 can provide thrust, so that the fresh macadamia nuts can pass under the lower pressure roller 2 to complete the crushing of the green skin.

[0022] In a preferred embodiment, Figure 2 As shown, a push plate 10 and a screw 11 are provided on the support frame 3. The push plate 10 is installed on the inner side of the support frame 3 through the guide protrusion 7, and the screw 11 is installed on the upper part of the support frame 3 through a thread, and the end of the screw 11 is sleeved on the upper end surface of the push plate 10. The lower part of the push plate 10 is connected to the upper part of the slider 4 through a spring. The height of the screw 11 can be adjusted to control the compression degree of the spring, thereby controlling the pressure of the lower pressure roller 2 on the fresh macadamia nut fruit, so that the pressure can break the green skin without breaking the wooden shell of the macadamia nut, thereby achieving efficient de-greening.

[0023] Preferably, a limit rod 12 is provided on the slider 4, the lower end of the limit rod 12 is fixedly connected to the slider 4, the upper end of the limit rod 12 passes through the push plate 10, and a limit cap is provided on the upper part of the limit rod 12. When it is necessary to lift the lower pressure roller 2, the push plate 10 can be driven to move upward by the screw 11, and then the slider 4 is pulled up by the limit rod 12 to move the lower pressure roller 2 upward, and the limit rod 12 can limit the slider 4 to keep it sliding in a straight line.

[0024] In a preferred embodiment, a rubber layer 13 is provided on the outer periphery of the lower pressure roller 2. The rubber layer 13 is vulcanized rubber and has a certain hardness. It can crush the green skin and rub the outer side of the macadamia nut to separate the broken green skin from the nut.

[0025] In a specific embodiment, there are multiple lower pressing rollers 2, and the multiple lower pressing rollers 2 are installed on the frame 6 at intervals along the moving direction of the plate chain 5. The de-greening efficiency is improved by repeated rolling of the multiple lower pressing rollers 2.

[0026] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
