Description
Technical field
This utility model relates to a kind of die head device, is specifically related to one and can be used for screw extruder extruding and produce highly oriented
The molding die device of degree noodles.
Background technology
Extruding be collection mix, stir, crush, heat, steaming and decocting, sterilize and be molded as one energy-efficient, economical and practical
Novel foodstuff process technology, have broad application prospects in noodles processing industry.
Flour is the primary raw material making noodles, flour material pre-quenched before be in glassy state, after entering extruder barrel
Temperature gradually rises, and under the conveying of screw rod, flour gradually changes to elastomeric state, molten state from glassy state.It is in molten state
High-molecular biologic polymer (mucedin, starch etc.) has higher compliance, thus along the direction generation Wei of shearing force
Gloomy fort effect (bag axle phenomenon), now high polymer rearranges along the direction of screw acting power, is orientated；Certain when having
Orientation material arrive machine barrel die head time, at a higher pressure high polymer molten mass when rotation circulation flows outer skin materials to
Interior extruding also elapses forward, is orientated by rotational shear effect；When high polymer molten mass is from the narrowest die orifice extrusion, one
At aspect runner die orifice, streamline shrinks, and molten mass is stretched power effect in the flowing direction, produces elastic deformation, but melt exists
In nib, the time of staying is short, and elastic deformation has little time fully relaxed, goes out the follow-up continuous reply of nib；On the other hand, molten mass is at mould
Produce elastic deformation because of shearing stress and normal stress effect during flowing in head, also to continue after going out nib to reply, therefore molten mass
Barus effect (extrudate swell phenomenon), Gao Ju is there is under the effect of complex fluid stress and die head runner and hole shape
Thing is orientated further.This macromolecular chain, segment or crystallite are under outfield (shearing force, tensile force etc.) acts on, along a certain spy
The phenomenon determining direction ordered arrangement is referred to as orientation, and orientation macromole, segment etc. are then orientation along the degree that fiber axis is regularly arranged
Degree.
In extruding noodles produce, extruder molding die device is portion maximum on the impact of the product degree of orientation in addition to screw rod
Part.The basic function of extrusion die is molding, i.e. gives finished product required form and size by runner and discharging opening perforate design.
Extruder molding die device is often under the high pressure of 3-10MPa and the condition of high temperature of 100-200 DEG C, die head stream in such circumstances
Road and perforate design are notable on product orientation impact.Less on the research of product orientation impact about die head device both at home and abroad, people
Often according to experience design die head, due to lack theoretical basis, made die head limits to a certain extent and hinders
The orientation of product high molecular polymer.
Accompanying drawing 1～3 is the die head device schematic diagram commonly used in current noodle extrusion technique respectively, this die head device bag
Include one runner through die body of die body and die body central authorities, runner two ends be respectively cylindrical charging aperture and with
The cylindrical discharging opening of its connection.Melted flour material enters die head by the charging aperture of die head, is formed expanded from discharging opening
Or unpuffed material strip, the cutting of rotated cutting knife and obtain the noodles with certain length, then carry through wind, be dried, pack
To finished product.
There is following defect in existing noodles extrusion die device: the charging aperture runner of molding die device is anxious by big cylinder
Play is punctured into mould discharge door distribution place small column, material be full of after runner cannot Uniform Flow, there is certain orientation
The molten state material of degree, by the shearing force in non-oriented direction, tensile force effect, causes this to possess a macromolecule for certain orientation
The orientation of polymer melt is destroyed；Moreover, dead angle is contained in these runner many places, and in discharging opening, exit orifice junction is drastically
Shrinking, fused materials can form eddy current at dead angle and even reflux, and orientation is destroyed again, and so far the noodles degree of orientation significantly drops
Low, edible quality is poor；Specifically this die head device produce the easy broken strip of gained noodles, easily stick with paste soup, organize coarse, chew strength sense and
Penetrating sense is the most poor, and These characteristics shows that the mucedin in flour material fails to form homogeneous, stable albumen bag with starch
Wrap up in starch network structure；Blocking up additionally, the drastically contracted channel of this die head also easily causes material, locally over-heating can cause again
Material is charred, to such an extent as to extruding machine cavity pressure excessive and cause danger or cause extruder start automatic defence program and stop
Produce；Discharging opening perforate is simple, finished product noodles kind single shortage new meaning, limit to a certain extent and constrain extruding noodles and
The promotion and application of correlation technique.
