Description

The nut hulling machine

The present invention is a kind of device that is used for broken nut shell, and the shell of this dry fruit is very hard as gingko, pine nut and so on.After shell removes, can reprocess after the boiling; Also can directly be processed into candy or wine brewing, or as the foodstuff of food, these food just can have been sold.

The device that is used for broken gingko, pine nut and so on duricrust and takes out its seed includes the facility of cutting nippers type.This example is at Japan practical authorization publication No.Deliver to some extent in 16535/38,2280/65 or 2679/52.This class hulling machine is normally clamped the shell of fruit, and is broken the shell folder one by one with cutting nippers then.The method of this poor efficiency does not satisfy the demand that increases day by day.Through development, adopted another kind of hulling machine recently, this installs at Japan practical authorization publication No.Deliver in 17515/77.This device is sent into a storage bin(hopper) to a large amount of nuts, nut from storage bin(hopper) fall one then holding of fruit receive in the trough, the time spent of doing that is subjected to vibrator when them just is in line one by one, sends into subsequently between the lower roller, shell is just by crowded broken.Compared with former device, yet this device has improved efficient, the adjusting difficulty of roller clearance in this hulling machine, shell has reached broken purpose sometimes, and inner seed has also suffered damage or has broken.Not very convenient for fear of the adjustment that produces this situation machine.In addition, this device must be earlier before the fruit fragmentation be arranged in rows fruit and just can enters roller and carry out fragmentation, and productivity ratio still can not be satisfied the demand like this.

It is very low to adopt cutting nippers formula hulling machine to process nut efficient, though can not satisfy the demand in market take the roller type hulling machine with the former mutually specific efficiency increase, but because nut size variation scope is very wide, the then roll extrusion that particle is big is excessive, particle little through roller in addition do not break.Therefore also there is obvious defects.The present invention is at the shortcoming of above-mentioned two kinds of devices and propose.Its purpose just is to provide the nut hulling machine of a kind of high efficiency and function admirable.It can be processed a large amount of nuts and can not make inner seed damage.

According to content (see figure 3) playpipe 1 of the present invention is to be made by toughness pipe material (as stainless steel tube), cuts into suitable length, and its internal diameter is more slightly larger than the fruit external diameter that will process.The right-hand member of every playpipe 1 is connected with a compressed air cylinder 2 with screw thread.Fixedly mounting a compressed air regulating valve door 3 on the position of the first from left point slightly at the end of thread, this structure can make the air pressure in the pipe adjusted.Conveying pipeline 7 is tilted to the left above playpipe 1.1 fixedly connected with pipe, connecting portion is in the left side of control valve 3, and receives below the exit of groove 6 holding.Hold and receive groove 6 and be connected with the outlet of storage bin(hopper) 5, vibrator is equipped with in the bottom of storage bin(hopper) 5.The inclined-plane is processed in the lower end of conveying pipeline 7, and the front end of this machined surface inserts left in the playpipe 1 slightly, and the machined surface rear end then flushes with the inwall of playpipe 1.When nut is input in the playpipe 1 through the cut ends left part of conveying pipeline, the gas shock of this moment conveying pipeline 7 and is stretched into inclined-plane front end in the playpipe 1.From the cross section of playpipe 1, airflow direction turns to the playpipe center, thereby stream pressure descends at this place, thereby fruit can fall in the playpipe 1 more reposefully, also make simultaneously compressed air produce rotation and drive fruit with a kind of faint eddy current form and also rotate, nut just is moved to the left rapidly with rotation status in pipe.The cavity in broken shell chamber 8 is the external diameter that garden its internal diameter of cylindricality (see figure 4) is a bit larger tham playpipe 1.The one end sealing in chamber, the left end of playpipe 1 injects in this chamber and fixes.The other end in broken shell chamber 8 opens wide, and seals with a backing plate 9.Backing plate 9 tightly is pressed on the end face in broken shell chamber 8 by the end cap that one of outside has internal thread, and the external screw thread in the internal thread of end cap and broken shell chamber is tightened.The thickness of backing plate 9 is suitable, and the biend of this plate is densely covered grid or irregular graininess.It is 1 millimeter aperture that there is an aperture at the center.A rectangle aperture that Aspect Ratio is suitable is arranged at the cylindrical shell bottom, garden in broken shell chamber 8, and broken shell drops out through opening.In addition, broken shell chamber 8 guarantees that structurally the inserting end of backing plate 9 and playpipe 1 is at a distance of about 3 centimetres.

The playpipe of said structure and combination thereof are arranged in parallel within the below of storage bin(hopper) and are fixed on the frame of this device with suitable quantity.Conveying pipeline 7 is received the lower end of groove 6 and is linked to each other with resiniferous flexible pipe with holding.The right-hand member of every playpipe all is connected with compressed air cylinder.

Fig. 2 is the vertical view of drawing by overall picture of the present invention;

Fig. 3 is the front view that amplifies, and it is cut open along center line;

Fig. 4 is that broken shell chamber 8 parts decompose front view and two side views that come;

Fig. 5 is the bottom view in broken shell chamber.

The nut of processing is put in the storage bin(hopper) 5, holds and receives in the groove 6 because the effect of vibrator makes nut fall.Compressed air enters in the compressed air cylinder 2, and turning handle is opened valve 3.High-speed air enters in the every playpipe 1, blows the nut of being come in by conveying pipeline 7, and nut is along with air-flow flings to left end, with backing plate 9 vertical collisions.Because the fragmentation of nut shell as a result of collision effect, the shell of seed and fragmentation drops out through the opening in broken shell chamber 8.Because there is an aperture 11 at backing plate 9 centers, compressed air spills out forward from aperture like this.Therefore nut is blown forward by air-flow, vertically impinge upon on the

backing plate

9, and 9 two end faces of pad are to make network-like or irregular grain shape, the accurately vertical collision of nut and can not produce horizontal slippage like this with backing plate, thus realized good broken shell effect.Said apparatus shows by test: the nut that is tried is its size no matter, and its shell is hundred-percent can be broken, and the shell of nut fragmentation and seed thereof follow compressed air to fall down through the opening part of bottom, broken shell chamber.Therefore for the nut of this class of gingko, because seed is very solid, accepting the broken shell that falls down from opening and the container of seed can be hard.If the seed of nut is softer, the seed of pine nut for example, broken easily or damage when they fall, at this moment then their container adopts screen cloth or silk screen for well, and it is only that net is considered to, because of it can also make compressed-air actuated reaction force attenuation.

Have following advantage or usefulness by hulling machine of the present invention:

No matter a. the fruit size size can make the whole broken shells of the fruit that is tried;

B. miniaturization that can implement device is because the length of playpipe just has satisfied effect when being about 1 meter;

C. this device has high economic benefit, because the handle of control valve can make the interior air mass flow of playpipe and the nut quantity of the broken shell of wanting adapt, and accomplishes a suitable flow.

D. device is with low cost.
