Description

Technical Field

[0001] The utility model relates to the field of nut processing machinery and equipment, in particular to a macadamia nut opening device. Background Art

[0002] Macadamia nuts are a kind of nut food with rich nutrition and delicious taste, which is deeply loved by people. Generally, they are processed into two forms of food, one is food sold with shells, and the other is pure nut food without shells. However, due to the special hardness of the shell, the method of breaking the shell is not like walnuts, which can be achieved by knocking or squeezing, but needs to be achieved by sawing. The existing technical equipment uses a single-piece circular saw, such as the patent number 2016103983460, a macadamia nut large-angle slotting machine public technology, which ring saws a slit in the shell to achieve the purpose of breaking the shell. However, this single-piece circular saw has an obvious but difficult to solve problem, that is, the saw disc will saw the kernel during the sawing process, which not only causes a large loss of the kernel, but also greatly reduces the quality of the product. The reason is that the depth of the sawing during the sawing process must exceed the thickness of the shell, and the saw disc will naturally saw the kernel. In order to ensure the necessary strength, the thickness of the existing single-piece saw disc must be higher than 1.5 mm, generally 2-2.5 mm thick. Since the fruit is a product of natural growth, the size and shape of each one are different, and the saw depth is difficult to control. If a 2 mm thick saw disk is used, the loss of the nut kernel may reach one-third, which is a problem that needs to be solved urgently. Summary of the invention

The two outer saw disks overlap on two sides of the middle saw disk respectively. The two outer saw disks overlap with the middle saw disk on the same axis. The axial cross-sectional structure of the outer saw disk teeth is a right triangle. The saw surface of the right-angled side of the right triangle overlaps with the middle saw disk. The diameter of the middle saw disk is 2-8 mm larger than the diameter of the outer saw disk. The diameter of the middle saw disk is 0.1-1 mm, and the diameter of the outer saw disk is 1-3 mm.
