Abstract
The invention discloses a differential pressure shelling device for dry nuts in the field of nut shelling, and particularly relates to a shelling device for breaking fruit shells through high pressure for the nuts with complete shells. Manual shelling is low in efficiency, and mechanical shelling is easy for damaging kernels and the appearances of the kernels are affected. The invention aims to reduce the damage caused to the kernels by mechanical shelling and break the nut shells by using higher atmospheric pressure differential pressure. The technical scheme is that: a gas container is divided into a high pressure region and a normal pressure region; the atmospheric pressure of the high pressure region is maintained at three atmospheric pressures; an electromagnetic gas valve is arranged between the high pressure region and the normal pressure region; and a certain amount of air of one atmospheric pressure is remained between the kernels and the shells of the dry nuts, so that the fruit shells can be broken by higher differential pressure of the atmospheric pressure on the inner side and the outer side. The differential pressure shelling device has the beneficial effects of breaking the nut shells by using instant high differential pressure, guaranteeing high efficiency and quickly balancing the differential pressure without damaging the kernels.
Description
Technical field
The present invention relates to the nut intact nut in field, particularly shell of peeling off and crush the peeling apparatus of shell by high pressure.
Background technology
The intelligent of manually peeling off, but efficiency is lower; Mechanical descaling, the pulverizing of shell is without solid shape, and shuck is relatively hard, shell easily damages kernel, has influence on the product phase of kernel.
Pneumatic sheller for peanut CN88214011.6, peanut draught head peanut-bursting method and peanut-bursting sheller CN88100878.8 thereof, need to wait for that peanut shell inner and outer air pressure equates, efficiency is low.
Summary of the invention
The object of the invention is to reduce the injury of mechanical descaling to kernel, adopt larger draught head to crush shell.
The present invention realizes the technical scheme that goal of the invention adopts: a gas container, be divided into higher-pressure region and atmospheric area, and the volume of higher-pressure region is 10 times of atmospheric area; Pump-up device adopts air compressor, and higher-pressure region makes air pressure maintain three atmospheric pressure by the air inlet pipe of air compressor; Higher-pressure region and atmospheric area have an electromagnetic type gas valve; Dry nut, due to the evaporation of moisture, dwindling of kernel, between kernel and shell, leave certain space, this space is filled by an atmospheric gas, and the peanut of half box or the dry nut of walnut class are put into atmospheric area, sealing atmospheric area, open rapidly gas valve, allow the gas moment in high-pressure area be diffused into atmospheric area, because High Pressure Difference inside and outside the sealing effectiveness to a certain degree of shell and instantaneous shuck causes shuck to break; The moment that shuck breaks, before inside and outside differential pressure does not have balance, now shell weakened, breaks and can further expand, and more suitable pressure difference can make shuck break well, and after shuck breaks, the rapid balance of inside and outside differential pressure, can not damage kernel; Then close gas valve, open the door of atmospheric area, take out the nut that shell breaks, carry out the mask work of kernel and shell.
The differential peeling apparatus of dry nut, is made up of gas container, pump-up device, gas valve, spring, electromagnet, it is characterized in that: a gas container, be divided into higher-pressure region and atmospheric area, and the volume of higher-pressure region is 10 times of atmospheric area; Pump-up device adopts air compressor, and higher-pressure region makes air pressure maintain three atmospheric pressure by the air inlet pipe of air compressor; Between higher-pressure region and atmospheric area, there is an electromagnetic type gas valve, control gas valve by electromagnet and spring; Atmospheric area has a dry fruit inlet/outlet.
The invention has the beneficial effects as follows: utilize the high pressure official post shuck of moment to break, efficiency is high; Pressure reduction is balance rapidly, can not cause damage to kernel.

Detailed description of the invention
A gas container 1, is shaped as hollow cuboid, and long 50cm, wide 100cm, high 200cm, be made up of high-strength aluminum alloy or stainless steel material, and thickness is 10mm, taking cost into account, also can use the reinforced concrete body of wall of 100mm.
Gas container 1 is divided into higher-pressure region 2 and atmospheric area 3, and there is a dividing plate centre, and the thick 10mm of dividing plate adopts high-strength aluminum alloy or stainless steel material to form.
Sealing plate 4 and sealing handle 5 separate gas container and extraneous atmosphere, sealing plate 4 is with plastic sealing gasket, this passage is used for getting and placing nut, nut is by a metal frame turnover atmospheric area, the size of this metal frame is: long 90cm, wide 40cm, high 15cm, hold the nut of 10cm height, put into atmospheric area, then set up sealing plate 4 and fit sealing handle.
Higher-pressure region 2 makes air pressure maintain three atmospheric pressure by the air inlet pipe 12 of air compressor.
Disconnect electro-magnet switch 13, the sealing plectane 6 of the air pressure official post band sealing gasket of higher-pressure region 2 and atmospheric area moves down, gases at high pressure are diffused into rapidly atmospheric area 3, high pressure outside normal pressure and shell in shuck makes shuck meet with huge pressure and breaks, after shell breaks, inside and outside differential pressure balance, can not cause the further injury of shell to kernel, after atmospheric area and higher-pressure region pressure equilibrium, spring 10 pulls on stainless steel cylinder 9 and moves, the air valve pull bar 8 linking together with stainless steel cylinder 9 seals on plectane 6 and moves with band sealing gasket, air valve aperture 7 is closed, open electro-magnet switch 13, electromagnet 11 produces enough magnetic field closes air valve aperture 7, air compressor is inflated and is maintained the higher atmospheric pressure of higher-pressure region by air inlet pipe 12.
Outward winding and seal handle 5, open sealing plate 4, take out the nut after peeling off.
