Description

Technical Field

[0001] This utility model belongs to the field of chestnut shell separation technology, and in particular relates to a chestnut shell separation device. Background Technology

[0002] Chestnuts are deciduous trees belonging to the genus Castanea in the family Fagaceae. They have thick, cylindrical stems and branches with a dark green surface covered with fine longitudinal stripes and small hairs. They are a popular food among modern people. After chestnuts are picked from the tree, they need to be removed from their spiky shells. This step used to be done manually, but because the chestnut shells have hard thorns, manual operation is not only inefficient but also prone to injury. Therefore, people later designed some devices for shelling chestnuts. The basic principle of this type of equipment is to use one or more sets of rotating rollers to simulate human kneading of the ions, so that the chestnut shell is separated from the chestnut inside, and then the chestnut and the shell are collected separately by air separation. However, the wind separation method still has some shortcomings. Because the chestnut shells are crushed and broken into different sizes, some chestnut shells with a similar specific gravity to the chestnuts may be mixed in with the chestnuts. This requires manual removal, which may result in injury. In addition, in order to ensure that the chestnut shells can be blown away smoothly, the chestnut balls need to be strictly dried before shelling, which is very troublesome. Therefore, it is necessary to design a chestnut shell separation technology device. Utility Model Content

[0003] This invention provides a chestnut shell separation technology device, which aims to solve the problem that the existing air separation method for separating chestnut shells and chestnuts has errors and easily leads to a certain number of chestnut shells mixed in with the chestnuts.
