Abstract

The invention discloses a shelling device for dry walnuts, and relates to the field of nut shelling, in particular to the shelling device for the dry walnuts. Nut clamping is suitable for families; and mechanical nutshell crushing is efficient, but the problem that the kernels are easy to break exists. A part of air exists in the dry walnuts. In order to overcome the defects that the kernels of the walnuts are easy to break in walnut crushing and the efficiency of pneumatic shell breaking is low, the invention provides the method for breaking the walnut shells. The technical scheme is that: the walnuts fall on a hard conical surface from a high feed port of 12-20 m, and the speed of reaching to the conical surface is 15-20 m/s; and since the air pressure in the walnut shells is increased because of deformation by collision, the breakage of the walnut shells can be promoted, and the walnut shells can also be broken if the deformation by collision exceeds the elastic deformation capable of being born by the walnut shells. The shelling device has the beneficial effects that the walnuts are only required to be conveyed to a high place by a conveying belt by using free fall motion, complex crushing equipment is not required, the equipment is simple, and the operation is convenient and economical.

Description

A kind of dried CRACKING WALNUT method

Technical field

The present invention relates to the peel off method for stripping shell in field, particularly dried walnut of nut.

Background technology

Nut is peeled off and is generally adopted folder, and the folder nut is suitable for family; Factory generally adopts machinery crushing shuck, and machinery presses shuck efficient, but the problem that exists is the breakage that causes kernel easily.

There is the part air dried walnut inside; There is the patent Shen to claim to adopt pneumatic peeling off: slowly pressurization; Gas penetrates into walnut inside, and sharply decompression is similar to puffed rice shell is popped then; Its subject matter is that the fine and close duricrust of walnut needs the long time could realize inside and outside air pressure balance to higher air pressure, and efficient is lower.

Summary of the invention

For overcoming the poor efficiency of pressing walnut shell to be prone to cause walnut kernel breakage and pneumatic broken shell, the present invention adopts the method for breaking walnut shell.

The technical scheme that the present invention solves its technical problem employing is: let walnut fall to hard conical surface from the eminence charging aperture of 12-20 rice; The speed that arrives conical surface reaches 15-20m/s; Cause the increase of walnut shell internal gas pressure can impel breaking of walnut shell because deformation takes place bump; Deformation takes place and surpasses the elastic deformation that walnut shell can bear walnut shell is broken in bump, that is to say that some damaged walnut shell itself also can be broken into pieces shell.Walnut shell is broken the back into pieces and is slipped to collection place collection along taper seat.When walnut shell is broken into pieces, because the cushioning effect of air in the protective effect of walnut shell and the shell can not injure kernel.At 15m/s, the height of whereabouts is at 12.5m for the speed of paper shell walnut suggestion; At 20m/s, the height that promptly falls is at 20m for harder iron-clad walnut suggestion speed.

The invention has the beneficial effects as follows: adopt the movement of falling object, only need conveyer belt that walnut is transported to eminence and get final product, do not need the complicated equipment that crushes, equipment is simple, easy to operate economy.

Fig. 2 is the charging aperture sketch map.

Wherein, 1, the loudspeaker face, 2, taper seat, 3, the taper seat bracing frame, 4, discharging opening, 5, device support stand, 6, charging aperture, 7, charging hole.

The specific embodiment

Walnut drops to the loudspeaker face 1 or the taper seat 2 of percussion device from eminence charging aperture 6; The material suggestion of loudspeaker face 1 or taper seat 2 is the reinforced concrete of thickness 10cm; Broken walnut kernel and the shell in bump back is slipped to discharging opening 4, and the purpose of taper seat is to avoid walnut directly to drop to discharging opening 4, and taper seat is fixed on the loudspeaker face through three taper seat bracing frames 3; The central authorities of loudspeaker face are discharging openings, and whole device is fixing through device support stand 5.

For large-scale factory work, 10 meters of suggestion loudspeaker face diameters, 2 meters of height; 1 meter of taper seat diameter, 0.5 meter of height is apart from 1 meter at the top of loudspeaker face; The diameter of discharging opening is 0.4 meter.

For guaranteeing that walnut evenly distributes, reach the purpose of even collision, charging aperture 6 is the circle of 5 meters of diameters; Material is an aluminium alloy, and charging hole 7 is the circle of diameter 8cm, each other be spaced apart 15cm; Charging aperture 6 is a taper seat, and is middle lower slightly, the charging hole cross-distribution; Assurance moves down all along any radius of taper seat can have charging hole, can effectively avoid piling up walnut in the bottom of taper seat.
