Description
Technical field
The utility model relates to the drawing mechanism of extrusion equipment in food and the field of feed processing, particularly relates to the extrusion equipment drawing mechanism that needs reduce discharging pressure.
Background technology
Extruding and puffing technology is widely used in field of food and field of feed processing already.Existing drawing mechanism includes fixed mount, and fixed mount links to each other with venturi one side, the venturi opposite side is provided with forming panel, forming panel is provided with some nibs, and described forming panel fixes through pressing plate and venturi, and the forming panel center is provided with deflection cone towards venturi one side.Material through certain precuring in the course of work of extruder moves to discharging nib direction by rotatable screw rod, material from charging aperture to this section of discharging nib process, material is subjected to the effect of powerful mechanical energy by rotatable screw rod in extruder, material temperature, pressure promote gradually, before material arrives the discharging nib, the gelatinization degree of material reaches high state, and material pushes the extruding grain products of the high gelatinization degree that comes out to obtain by cutting from the discharging nib subsequently.And in whole process of production, the quality and yield of extruding grain products is a pair of contradiction community all the time, is example with the aquatic feeds, and it is embodied in:
1, under the situation of high yield, the Builking cavity internal pressure is bigger, and the product dilation that extrusion comes out is bigger, and at this moment the requirement that is above standard of its coefficient of expansion just needs to sacrifice output and reduce the product dilation.
2, be under the situation of high yield equally, the current difference opposite sex of material flow in drawing mechanism utility model more shows, fast, the peripheral flow velocity of flow velocity is slow in the middle of the forming panel, causes the product particle size inhomogeneous more obvious, at this moment need limit output equally and satisfy product quality.
3, for requiring the higher high-grade seawater feed of screw rod shearing force rate, output is to be subjected to shearing force restriction that screw rod can provide.
4, (as discharging nib φ 1.0mm) during production small-bore aquatic products material, fiber in the material can constantly hang between the Kong Yukong of template along with materials flow, and then the blocking portion template makes output constantly descend, and this situation is produced usually and promptly can be taken place in 2-3 hour, need dismantle cleaning.
The utility model content
The purpose of this utility model provides a kind of bulking machine bimodulus plate drawing mechanism, makes materials flow flow speed stability before arriving nib, and pressure is even; Pressure can suitably reduce before arriving nib, to obtain better expansion effect, simultaneously, can improve output.
The purpose of this utility model is achieved in that a kind of bulking machine bimodulus plate drawing mechanism, comprise fixed mount, venturi, deflection cone and forming panel, described forming panel is provided with some nibs, described fixed mount is arranged on venturi one side, be provided with the template frame between described venturi and the forming panel, deflection cone is fixed on the template frame center towards venturi one side, be provided with the pressure regulation template between venturi and the template frame, pressure regulation template center is sleeved on the root of deflection cone, described pressure regulation template is provided with some through flow holes, and the flow area sum of described through flow hole is greater than the flow area sum of described nib.
The utility model adopts the design of the bimodulus plate of pressure regulation template and forming panel, make the flow area sum of the flow area sum of through flow hole simultaneously greater than described nib, after having guaranteed that material is through the pressure regulation template, the space that a voltage stabilizing is arranged, make material flow even simultaneously, and then guaranteed end product quality homogeneous, stable, expanded appropriateness; Particularly, the utlity model has following effect:
1, hypotensive effect: material extrusion process is the state of a HTHP.Can be subjected to resistance when material process pressure regulation template, this resistance has played certain hypotensive effect, makes material arrive the preceding pressure of forming panel and diminishes, can be so that the final expanded coefficient of material diminishes.And the bulking machine of a same specification, output is big more, and the Builking cavity internal pressure can increase, and causes the final expanded coefficient of material to become big; In normal productive process, in order to control expanded coefficient, often need to limit output sometimes.The utilization of the utility model structure has increased the step-down process before depanning, thereby can further improve output under the prerequisite that guarantees expanded coefficient.
2, rectified action: because during the screw to convey materials of bulking machine, the flow velocity of outside material there are differences in spiral, make materials flow have current difference equally when arriving venturi, when the pressure regulation template is passed in materials flow after, between pressure regulation template and forming panel, formed a little commutating zone.This commutating zone can not be eliminated materials flow periphery and middle current difference fully, but can alleviate the influence of staying fast difference band.When inhomogeneous being eased of product length that current difference brings, the production capacity of bulking machine can promote thereupon.
3, shear action: the pressure regulation template is provided with some through flow holes, and material has not only increased resistance by the pressure regulation template time, has also increased the shearing force to material simultaneously.When requiring little heavy forage, select the pressure regulation template that opening diameter is big, perforate quantity is many to process for the processing shearing force; And when requiring than higher seawater buoyant and frog material for the processing shearing force, we can select the pressure regulation template that perforate is little, perforate quantity is few, replenish shearing force.We can reduce the shearing force of screw rod as far as possible when selecting screw arrangement like this, to improve the production capacity of dilated product.
4, cleaning action: in the production of small-bore, the fiber in the material can hang on the forming panel, finally stops up the problem of nib.And in the utility model, the flow area sum of through flow hole is greater than the flow area sum of described nib, make that the spacing of through flow hole can be smaller on the pressure regulation template, be more prone to tangle fiber and be not easy plug-hole, be suspended on the forming panel even there is small amount of fibers to pass through the pressure regulation template, can effectively prolong the production time of small-bore product equally.
Compared with prior art, the utility model also can improve output when obtaining better expansion effect.It can be applicable in the production of various dilated foods, feed.
As further improvement of the utility model, described template frame comprises the centerbody that is outer ring cylindraceous and is round pie, links to each other through disc between described outer ring and the centerbody; Be connected through screw between deflection cone, forming panel and the centerbody.
As preferred version of the present utility model, the ratio of pressure regulation template to the cavity volume between the forming panel and venturi aditus laryngis to the cavity volume between the pressure regulation template is 1.2-2.In this volume ratio scope, can guarantee that expanded material discharging is even, output is higher simultaneously.
For ease of making, described through flow hole is some circular holes.
For conveniently installing and fixing, described pressure regulation template cooperation is installed in venturi and exports a side, and the template frame is axially fixed in venturi through hold-down ring with the pressure regulation template and exports a side.
