Description
Technical field
The utility model relates to the extrusion equipment in food and the field of feed processing, particularly relates to a kind of mechanical device of effective raising extrusion device fabrication line service efficiency.
Background technology
Extruding and puffing technology has been widely used in field of food and field of feed processing.Generally speaking, the extruder of extruded food or feed can be a single serew bulker, also can be twin-screw Bulking Machine, or even the multiscrew bulking machine.Such bulking machine comprises the extruding cylindrical shell of the tubulose of certain-length, the extruding barrel tip connects one makes the bound material discharging mould of the material that is extruded, material discharging mould is provided with some discharging nibs, in the inside of extruding cylindrical shell one or more extruding screws is arranged.Extruder is when operation, there is steam to be injected into the extruding inner barrel under normal conditions, in the extruding cylindrical shell, the be squeezed effects such as shearing, friction, conveying, mixing of screw rod of the material of certain moisture content and uniform temperature, the progressively slaking of starch in the material, finally extrude and be cut, obtain the swelling granular after expanded by the discharging nib.
Common extruder extruding barrel tip is the structure of a tapered contraction, and main purpose is the extruding force that strengthens material, improves the slaking effect of material, but such structure can have influence on the lifting of extruder production capacity, simultaneously, because when the discharging of discharging nib, material moment is expanded, water in the material is vaporized rapidly, cause the moisture content of material to reduce too much, it is big that material fragility becomes, the elasticity variation, when storage, transportation, material is squeezed into powder easily; In addition, for specific material, for example aquatic feeds needs its moisture content of control to be unlikely to very few, has certain density to guarantee it, in the time of in throwing in entry, can keep floating state or sink to the bottom state.
For promoting production capacity, can make extruding barrel tip flow area become gradually greatly, simultaneously, can on material discharging mould, offer and more have more the material nib, the discharging nib is dispersed on the material discharging mould, although such structure can promote production capacity, but has brought the uneven problem of swelling granular of extruding.Main cause is, the flow area of extruding cylindrical shell amplifies gradually, the opening area of the discharging nib on the corresponding material discharging mould is also just corresponding to be amplified, the discharging flow of the apertura lateralis of position of opening and inboard aperture is inconsistent on the material discharging mould, the pressure of both correspondence positions is also inconsistent, and this has just directly caused the swelling granular of extruding simultaneously inhomogeneous.The inhomogeneous one side of particle is that its size is inhomogeneous, influence the product phase of material, be that its expanded level is inconsistent on the other hand, this can influence the density of material, and then change its buoyancy, for aquatic feeds, during as input, part swims in the water surface, part sinks under water, and then is underproof substantially.
How guarantee when improving the bulking machine production capacity that material has good homogeneous degree, stable moisture content, this is the technical barrier that those skilled in the art need to be resolved hurrily.
The utility model content
The utility model provides a kind of multiple-discharge-channel extrusion bulking machine, makes it can overcome the deficiencies in the prior art, when improving the bulking machine production capacity, can guarantee the discharging uniform particles, and water content is stable.
For solving the problems of the technologies described above, a kind of multiple-discharge-channel extrusion bulking machine that the utility model provides, comprise extruding cylindrical shell and material discharging mould, cooperate in the described extruding cylindrical shell and be provided with one or more extruding screws, material discharging mould is provided with some discharging nibs, be provided with fluid amplifier between described extruding barrel tip and the material discharging mould, evenly distributed ringwise on the described fluid amplifier have at least three tapping channels, and described each tapping channel equal and opposite in direction, shape on the same longitudinal cross-section of fluid amplifier is identical; Less than the flow area towards material discharging mould one side, tapping channel is tapered to be distributed in around the axis that pushes cylindrical shell the corresponding setting with tapping channel of the discharging nib on the described material discharging mould to described tapping channel towards the flow area that pushes cylindrical shell one side.
During this device work, material is extruded screw rod and pushes to the material discharging mould direction in the extruding cylindrical shell, at effects such as the shearing of extruding screw, friction, conveying, mixing, progressively slaking of the starch in the material, material diversion then, enter in each tapping channel of fluid amplifier, in each tapping channel, the material appropriateness expands, and the moisture content in the material still is constrained in the fluid amplifier, can not flash evapn, help keeping having abundant moisture content in the final products; In addition, the structural design of tapping channel has guaranteed that the distance of material arrival discharging nib equates that the pressure in each tapping channel is all consistent, thereby makes the discharging uniform particles, and water content is stable.Tapping channel is tapered to be distributed in around the axis that pushes cylindrical shell, makes material discharging mould have enough positions to offer more discharging nib, to guarantee the production capacity of bulking machine.Compared with prior art: the utility model can improve production capacity owing to adopted fluid amplifier, simultaneously, can guarantee that still product is even, and water content is stable.
For keeping the moisture content in the product particle to be unlikely to lost more, described tapping channel evenly amplifies from extruding cylindrical shell one side direction material discharging mould one side, and perhaps described tapping channel is near the tapered amplification of material discharging mould one end.Above-mentioned two technical schemes can guarantee that all material had just carried out once expanding before leaving the discharging nib, pressure is able to part and discharges, and when expanded, the moisture content in the material is unlikely to undue and scatters and disappears final, guaranteed that product particle has certain water content, the fragility of product is suitably controlled.The preferred discharge area for described tapping channel of this scheme is 1.1-3.2 with the ratio of inlet-duct area.
As further improvement of the utility model, described material discharging mould is provided with more than three with tapping channel is corresponding one by one.Described material discharging mould also can only be provided with one, can be provided with on the material discharging mould and the tapping channel discharging nib more than three groups one to one.
As further improvement of the utility model, be provided with baffle between described extruding cylindrical shell and the fluid amplifier, the baffle center is provided with the deflection cone of the tapping channel that material can be led.The setting of deflection cone can make that material is more smooth to be entered in each tapping channel.
As further improvement of the utility model, the rounded or long oval shape in the longitudinal cross-section of described each tapping channel.When the longitudinal cross-section of tapping channel was rounded, it was easy to process on the one hand, can make Flow of Goods and Materials more smooth and easy on the other hand, helps making the inside isostasy everywhere of material; When the longitudinal cross-section of tapping channel was long oval shape, the interval between the adjacent tapping channel was less, can the utilized areas that utilize material discharging mould more, improve production capacity.
