Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of peeling machines, in particular to a small-sized green walnut peeling device. BACKGROUND

[0002] Walnuts not only contain rich nutrients such as protein, fat, and carbohydrates, but also contain various trace elements such as calcium, phosphorus, and iron, as well as various vitamins such as carotene and riboflavin.

[0003] Green walnuts grow on walnut trees as a kind of fruit. A green walnut is composed of a walnut body and an inner pericarp and an outer pericarp successively wrapped outside the walnut body. Since the walnut body has high nutritional value and is used as a kind of nut food, people often need to peel the outer pericarp and the inner pericarp wrapped outside the walnut body.

[0004] The inner pericarp and the outer pericarp together form green skin, which is fleshy skin. Although different varieties of green walnuts have no obvious differences in appearance, there are obvious differences in the thickness of the corresponding green skin. Unripe green walnuts are difficult to remove because the green skin is closely adhered to the nut. Ripe green walnuts have partial cracks in the green skin, and most of the green skin is no longer adhered to the nut, making it easy to remove. The green skin has high brittleness, and the breaking strength is much smaller than that of the walnut shell. The ideal peeling effect is that when the green walnut is subjected to a certain mechanical external force, the green skin is cracked and broken, and the walnut shell remains intact.

[0005] There are three main mechanical methods for removing the green skin of walnuts: scraping, cutting, and extrusion. The working principle of the scraping method is that the green walnut passes through a gap, and the walnut green skin is scraped off under the shearing force of the concave plate wire brush and the drum grid. The cutting method is to cut the green skin by relative movement of the blade and the green walnut, and then use friction to peel it off the walnut surface. The extrusion method is to cause the green skin to crack and crack by extrusion of the compression plate, and then separate it from the walnut shell under the action of the compression plate and the drum rubbing.

[0006] However, the current three mechanical methods for removing the green skin of walnuts are complicated to operate, and the cleaning effect is poor. They are often suitable for large-scale peeling in factories, but are not convenient for use in daily life and are not suitable for small-scale use such as in families. SUMMARY
