Problems solved by technology

However, the agent can enter the nuts through the cracks in the inner hard shell of the walnut, causing the nuts to be polluted
[0006] After the walnut is harvested, the green peel is directly peeled off by mechanical method. The outer green peel of the walnut fruit is firmly combined with the uneven inner hard shell, and it is difficult to remove the green peel. Therefore, the rolling and shearing strength must be increased. method, after the green fruit skin is peeled off by operations such as rolling and rubbing, there is also a process of scrubbing the inner hard shell of the walnut fruit with a rolling brush, which leads to a higher broken rate of the inner hard shell and a low commodity rate. The equipment and site environment are poor, and the processing produces pollution and sewage
[0007] In addition, there is another method of peeling walnut green skin after freezing. Although it is also green and environmentally friendly processing, the initial freezing investment is relatively large. In summary, the existing walnut green skin peeling technology cannot better meet market demand.

Embodiment Construction

[0030] The present invention will be described in further detail below in combination with specific embodiments and accompanying drawings.

[0031] like figure 1 As shown, a system for ethylene gas ripening and stripping walnut green peels includes a closed box body 1 and a multi-layer wire mesh conveyor belt 2 arranged in the box body 1, and the transmission direction of two adjacent layers of wire mesh conveyor belts 2 On the contrary, and in the adjacent two layers of wire mesh conveyor belts 2, the starting end of the lower floor wire mesh conveyor belt 2 protrudes from the end of the upper floor wire mesh conveyor belt 2; Feeder 3, the lower opening of the feeder 3 corresponds to the starting end of the top-layer wire mesh conveyor belt 2, and a discharge port 8 is provided on the bottom surface of the box body 1, and the position of the discharge port 8 corresponds to the end of the bottom wire mesh conveyor belt 2. A rubbing and peeling device 10 for separating the gre...

Abstract

The invention discloses a system and a method of removing green peels of walnuts through ethylene gas ripening. Green-peeled walnuts are poured into a box from a feeder and dropped onto a top wire mesh conveying belt in the box, the green-peeled walnuts are slowly conveyed from an entry of the box to an exit of the box, and a gas ethylene generator enters the box during conveying and performs ethylene gas ripening to the green peels of the walnuts; after the green peels are ripened, the walnuts directly fall into a rubbing stripping unit from the tail end of a bottom wire mesh conveying belt, and the green peels and inner hard shells of the walnuts are separated. Gas ethylene is used to ripen the green peels o the walnuts and remove the green peels; removal rate of the green peels is high; breakage rate is low; yield of commercial walnuts is high; efficiency is high; the use of the gas ethylene in ripening the green peels prevents kernels from being contaminated, resulting in food contamination; meanwhile, the processing process is green.

Description

technical field [0001] The invention belongs to the technical field of walnut green peel peeling, and in particular relates to a system and method for peeling walnut green peel by ethylene gas ripening. Background technique [0002] Walnut fruit is mainly composed of three parts: the outer green peel, the inner hard shell and the kernel. When the green peel is ripe and cracks appear on the surface, the walnut nut and the green peel are easily separated and peeled off. But due to various reasons, when the walnut fruit was harvested, the green peel was not ripe yet. At this time, the green peel of the walnut was firmly combined with the inner hard shell of the walnut fruit, which made it difficult to peel off the green peel of the walnut outer layer, and the peeling of the green peel of the walnut The processing process has an important influence on the commodity quality of walnuts. [0003] Existing walnut green peeling methods are many, including stack retting peeling meth...
