Device for automatically removing walnut green husks and application method of device

Abstract

The invention relates to a device for automatically removing walnut green husks and an application method of the device, and belongs to the technical field of the processing of agricultural products.According to the device disclosed by the invention, the gap between blades and steel wire plate brushes is controlled by a gap adjuster to adapt to walnuts in different shapes and sizes, and the removing of the green husks of the walnuts in different shapes and sizes is realized; the angle between a conveyor track and the wire plate brushes is controlled by an angle adjuster to adapt to the walnuts of different kinds, and removing of the green husks of the walnuts of different kinds is realized; in addition, the process of squeezing green walnuts from big size to small size can be achieved; the breakage rate of the walnuts is reduced; the rate of thoroughly removing green husks is increased; and the residues of the green husks on the surfaces of the walnuts are reduced. Firstly, the greenwalnuts are instantaneously frozen by liquid nitrogen freezers, the moisture in the green walnut husks is iced up by freezing, and walnut kernels become larger in size, so that the green husks burst open; then the frozen green walnuts are heated and thawed by resistance heaters, so that the green husks and the kernels are separated gradually; and the freezing and the thawing are cycled twice, so that the green husks and the kernels of the green walnuts are preliminarily separated. Thorough and rapid removing of the walnut green husks is facilitated, and the device is broad in application prospects.

Description

technical field [0001] The invention relates to an automatic walnut peeling device and an application method thereof, belonging to the technical field of agricultural product processing. Background technique [0002] Walnut is one of the world's famous four major nuts (walnut, almond, chestnut, cashew nut). China is a big walnut producer in the world, and its cultivation area and output rank first in the world. Its main distribution and cultivation areas are Yunnan, Xinjiang, Shaanxi, Shanxi, Hebei and other provinces, accounting for more than 70% of the country's total walnut production. Walnut fruit is mainly composed of walnut kernel, hard shell and green peel. After the fruit is harvested, the green peel should be removed as soon as possible, otherwise the walnut kernel will become moldy and affect the internal quality of the walnut. Walnut peeling is an important process of post-harvest walnut processing, which plays an important role in ensuring the quality of walnut...

Problems solved by technology

[0005] The technical problem mainly solved by the present invention: for the current peeling of green-skinned walnuts, the manual peeling and retting method is generally used, and the production efficiency is low, the cost is high, the labor intensity is high, and the hygienic conditions are poor, which seriously affects the appearance quality and inner quality of walnuts. quality, while some existing mechanical peeling devices have higher requirements on the size of green walnuts, larger green walnuts cannot enter the peeling area or be broken; smaller green walnuts are not easy to remove green walnuts due to the small extrusion force , and the defect of low productivity, a walnut automatic peeling device and its application method are provided
