Abstract

A method of forming elbow-shaped crackers using a die cutter is provided. By one approach, the method includes first preparing a cracker dough, and then sheeting the cracker dough to form a dough sheet having a thickness. Next, the formed dough sheet is advanced through a die cutter to form a plurality of elbow-shaped dough pieces from the dough sheet. The formed dough pieces have a non symmetrical degree of curvature between top and bottom sides thereof so that the formed dough pieces have a recognizable elbow-shaped configuration and the plurality of formed dough pieces are nested together by the die cutter so that there is no sheeted cracker dough remaining between adjacently nested dough pieces.

Description

For the production of the method for elbow biscuit

Technical field

This area relates to the method for the production of biscuit product, and more specifically relates to the method for producing elbow biscuit (elbow-shaped cracker) product with blanking punch.

Background technology

Biscuit product forms by following steps conventionally: cut required biscuit shape and cure the raw face of biscuit to form the biscuit product curing from the raw face thin slice of biscuit (sheet of cracker dough).Various schemes can be used for forming raw face and the raw face of cutting is that the sheet (piece) with required form cures.For example, each cutting machine or mould can be used for raw biscuit face to be formed as required form.More the process of automation relates to use blanking punch, the dough sheet shape before its restriction is cured.Blanking punch is attachable on reciprocating cutting plate or circumgyration incision cylinder.Under many situations, rotary cutting die is usually desirable, because the sheet that the raw face thin slice of biscuit can be fed to rotary cutting die and cut into its required raw face shape in continuous process is to increase output.

In the time using blanking punch, conventionally need to reduce not to be formed as the scrap material of biscuit shape or the amount of raw face, it can occur along areloe chip edge or by being placed in the space between each blanking punch on cutting machine.Have the various configurations of producing biscuit product with blanking punch, but each configuration can have shortcoming in the time being applied to asymmetric or thin shape (such as elbow biscuit).For example, it is relatively direct forming rectangle biscuit with blanking punch, can be easy to adjacent positioned and abut even each other to minimize and get rid of this waste because limit the cutting blade of rectangle biscuit.On cutting machine mould, tend to cause the waste increasing and the output reducing to be similar to the cutting blade that the mode bad seek of rectangle claims.

For circular biscuit, need to solve other difficulty and form high efficiency cutting mould.Due to its toroidal, the neighboring edge that is used to form the cutting blade of circular raw face shape can not be positioned in order to get rid of waste, thereby reprocesses because the material between cutting blade forms raw face during cutting.Conventionally expect this reprocessing and comprise that procedure of processing separates and recycle the raw face portion between cutting blade by the process of rotating mould.Generally speaking, the blanking punch that is used to form circular biscuit product can cause up to about 30% to about 33% waste material or reprocessing, thereby reduces output, and because complicated recirculation and reprocessing process increase waste or increase expense.In some cases, although circle can separate to cut the waste nested and tightly/reprocess, circular constraint is tended to because no raw face between excision mould blade causes waste or reprocessing to a certain degree.Equally, the cutting machine that adopts the technology that is suitable for round cutter sheet to be formed for asymmetric shape tends to cause unacceptable waste and output.

Although the designer of blanking punch is arranged in cutting blade shape on mould surface conventionally to reduce no part, circle as described above or the character of rectangle have provided relatively directly cutting blade alignment processes and have produced the most efficient mould configuration.For rectangle or circular biscuit, there is the single free degree in mould structure conventionally, and it is nested or abut and be configured to minimize or get rid of and excising no material between blade that excision blade is positioned to most probable by it.For asymmetric shape and not too conventional shape (such as the elbow stripping and slicing of relative thin), due to the many more freedoms that must consider, it is not straight-forward procedure to realize required excision that cutting blade is placed in the lip-deep tradition of mould.For example, in the time that formation mould excises the asymmetric shape (such as elbow) of asymmetric shape and particularly relative thin, not only need to select nested arrangement, and its given shape, any curvature (curvature) of this shape, weight, thickness and the width of this shape all must be considered.Adjust one of these parameters and tend to affect significantly mould configuration.Although difficulty is that formed biscuit need to keep the constraint of its asymmetric outward appearance, there is good output and minimum shapes of cutout of breaking but still form to produce by firm blanking punch and compressing tablet process.

The specific embodiment

Referring to accompanying drawing, the example procedure and the mould configuration that are used to form elbow biscuit are shown, it uses blanking punch, and blanking punch is configured to produce good output and has minimal product fragmentation.The shape of elbow biscuit is specifically configured to not only represent discernible elbow, and has the configuration of effectively producing on compared with less waste material blanking punch simultaneously, there is no that no material stays between adjacent cutting blade in compared with the blanking punch of less waste material.For this purpose, elbow biscuit has the top arc of formation biscuit shape and the concrete curvature of bottom arc, this keeps elbow configuration and allows nested arrangement (nesting arrangement), and between adjacent cross cutting piece, have very little or without displacement chamber, making this mould is the configuration compared with less waste material.

Generally speaking, first form the raw face of biscuit, by mixing raw face composition and making raw face ferment to form the raw face of biscuit.Afterwards, the desired thickness that is application-specific by raw biscuit face compressing tablet.Then raw face thin slice advances to blanking punch, it is preferably rotary cutting die, and in blanking punch, raw face thin slice processes will give birth to face thin slice perforation (perforate) as multiple elbow dough sheets by the multiple elbow cutting blades that are positioned on blanking punch outer surface.Then the elbow dough sheet forming cures certain hour to form elbow biscuit in uniform temperature in baking box.After curing, before packing, can carry out optional fine finishining step, such as oil is coated on biscuit, flavoring, spices and/or salt are applied on ripe biscuit.The raw face weight of combination, moisture and shape to be so that biscuit is formed with few fragmentation, such as being less than about 15% and be preferably less than about 5% fragmentation.

Blanking punch has blade configuration, thus its be selected as producing have can identify the dough sheet of elbow and also allow the raw face thin slice of cutting simultaneously and between adjacent cutting dough sheet essentially no waste material produce good output.In a kind of scheme, each other dough sheet (with the mould blade that is configured to form this dough sheet) has following configuration: it comprises the curvature degree of top side and bottom side, the inclination angle of dough sheet end, raw face weight and cause the external surface area of discernible elbow, and this shape that also allows blanking punch blades aligned can nest together with formation simultaneously, thereby make formed raw face thin slice essentially no material between die cavity on cutting machine surface.The variation of dough sheet configuration, size, weight or curvature also causes unlike the shape of discernible elbow or causes the shape of the mould configuration that has waste product between die cavity.

Go to Fig. 1, the example procedure that forms elbow biscuit with blanking punch is provided.First prepare raw face by the initial 10 cavernous body compositions (sponge ingredients) that mix to form the raw face in cavernous body or centre.The composition being included in the first blend step generally includes flour, yeast, enzyme, pigment and water, and they are blended together to form cavernous body or middle raw face in one or more steps.Afterwards, make middle raw face fermentation (proofed) 12 form the middle raw face of fermentation.Afterwards, the middle raw face that mixes extra composition and fermentation in the second blend step 14 forms the most lifelong face, and it can ferment 16 for the second time to form the raw face of biscuit.The extra composition being included in the second blend step generally includes flour, oil, salt, leavening agent, butter, cheese and spices.

According to a scheme, then the raw face of biscuit forms continuous raw face thin slice 18, and it has the desired thickness relevant to the desired thickness that cures the dough sheet forming before.In order to form thin slice, the raw face of biscuit can advance by one or more pairs of preforming rollers, and it makes the raw face of biscuit flatten to become to have the continuous raw face thin slice of uniform thickness substantially.In order to reach desired thickness, the multipair preforming roller that the most lifelong face can stand arranged in series processes to suppress gradually the most lifelong face face thin slice of making a living.In a kind of scheme, raw face thin slice is rolled until it has the roughly uniform thickness of about 0.030 to about 0.040 inch.Although such scheme can be used for life face to be formed as desired thickness, should more understand and also can use other appropriate method.

After raw face thin slice, advance to blanking punch, be preferably rotary cutting die, wherein give birth to cut 20 one-tenth of face thin slice and there is each dough sheet that can identify elbow, and there is no raw plane materiel material between the elbow sheet of each formation.As discussed in more detail hereinafter, the unique shape of elbow dough sheet makes the material that is arranged in essentially no waste between adjacent cutting blade on blanking punch.Finally, dough sheet fully cures 22 to obtain required moisture and then to pack 24 in baking box.Optionally, spices, additive and coating can apply 26 to curing on the outer surface of biscuit.In a kind of scheme, oil coating, salt and/or other flavoring based on cheese can be applied on the biscuit curing before packing.

As mentioned, preferably, blanking punch is rotating mould 30, and the example is shown in Figure 2, wherein when raw face thin slice excises each dough sheet through out-of-date from raw face thin slice below rotary die-cutter 30.According to this scheme, rotary die-cutter 30 is cylindrical tube 32, and it has outer surface 34, and outer surface 34 has multiple cutting die cavitys 36 of settling around on outer surface 34 and around outer surface 34 being laterally placed in.Form multiple cutting die cavitys 36 by cutter 38, cutter 38 are arranged on cylinder 32 outer surface 34 (referring to for example Fig. 5) with wavy or sinusoidal pattern, thus this effectively allow the nested arrangement of die cavity 36 get rid of between each cutting dough sheet need not or raw face portion of waste.As below explained in more detail cutter 38, form each cutting die cavity 36 by cutter 38, elbow biscuit shape 40 is arranged to form around in cutter 38 winding mold chambeies 36, wherein, 40 have top side 41 and bottom side 43, top side 43 has top or deep camber 42, bottom side 41 has bottom or small curve 44 (Fig. 3), thus produce discernible elbow dough sheet and also make simultaneously multiple die cavitys 36 on mould 30 can sinusoidal nested arrangement to form compared with the blanking punch of less waste material (referring to Fig. 5 and Fig. 6).

In a kind of scheme, the top curvature degree 42 of the top side 41 of biscuit shape is different from the bottom curvature degree 44 of biscuit shape bottom side 43.For this purpose, this combination of asymmetric deep camber 42 and small curve 44 allows life face to cut into discernible elbow, but still allows sinusoidal nested pattern to produce compared with the cut-off blade of less waste material, wherein essentially no no material between adjacent cutting blade.To explain in more detail curvature referring to Fig. 7 and table 1 hereinafter.

Go to Fig. 2 a moment, cylindrical tube 32 is rotatably mounted in framework (not shown) and is oriented to its axis X and is substantially perpendicular to the conveyer direct of travel of raw face thin slice along its axis X.Cylinder 32 comprises circumferential surface 34, and blanking punch 36 is placed in this circumferential surface 34.In this scheme, cylinder 32 is positioned at the position that raw face thin slice is received in conveyer (not shown) top, and raw face thin slice advances on conveyer.Cylinder 32 is from conveyor surface offset of vertical certain distance, and this distance approximates raw face sheet thickness.

Go to Fig. 4, each cutter 38 are radially extending from the cylinder circumferential surface 34 of rotary cutting die 30, wherein lower limb 62 is placed in cylinder 32 circumferential surface 34 and from this circumferential surface 34 and is radially extending, and upper cut edge 60 is being radially spaced with cylinder surface 34.Cutter 38 should have certain altitude, upwards measure cut edge 60 from lower limb 62, and it approximates or be slightly greater than the uniform thickness substantially of raw face thin slice.Thus, when cutter 38 at raw face thin slice by below it during through the raw face thin slice of out-of-date joint, cutter 38 will penetrate raw face to form and cutting elbow dough sheet.

Go to more details, will a preferred disposition of cutting die cavity 36 be discussed referring to Fig. 3.Each indivedual cutting die cavity 36 has the surrounding 40 that is elbow mould cup 31 forms, limits therein elbow recess 35.Elbow mould cup 31 is limited by spaced apart and bending respectively top side 41 and bottom side 43 and a pair of isolated end 39.As mentioned above, bending top side 41 and bottom side 43 respectively have respectively curvature degree 42 and curvature degree 44, they preferably differ from one another and therefore top side and bottom side asymmetric., does not extend in mode parallel to each other top side and bottom side.

Isolated end 39 relative to each other slopes inwardly, predetermined angle 50 or 51 between them.In a kind of scheme, the scope of the angle 50 between end 39 be about 20 degree to about 40 degree and preferably about 40 degree.Or angle can be defined as the angle of end 39 with respect to the horizontal axis Y in decile chamber 36.In the case, angle 51 will be conventionally about 20 degree between about 10 degree and about 20 degree and preferably.In addition, elbow mould cup 31 is included in the bent corners that between end 39 and top side 31 and bottom side 43, intersection point place forms and engages 52.

Die cavity 36 is configured to cutting and has the about 0.6 and dough sheet of about 0.7 gram to about 0.8 gram (every 10 dough sheets about 7 gram to about 8 gram) long-pending to about 0.8 square inch surface, and this is confirmed to be for formation is important as the dough sheet of discernible elbow biscuit and biscuit product and also allows the production of product to have less fragmentation or without fragmentation.Less surface area conventionally increases product crushing and more high surface area is conventionally and unlike typical elbow Italian type wheaten food (pasta noodle), and biscuit is expected as this shape.

As shown at Fig. 5 and Fig. 6, be produce elbow biscuit compared with the example of the preferred nested arrangement 74 of each die cavity 36 of less waste material mould, it also can form discernible elbow simultaneously.In a kind of scheme, nested arrangement 74 is sinusoidal pattern on the surface 34 of cylinder 30.This nested in order to realize, end 36 angle 50 relative to each other allows nested arrangement 74 to be this sinusoidal Pareto diagram with the asymmetric curvature 42 of surface area and top side 41 and bottom side 44 with 44 combination, has Huo Wu space, less space between adjacent die cavity 36.Especially, this configuration produces nested arrangement, and between each adjacent positioned die cavity 36, has displacement district (displacement area) 54, and this makes can be to cut compared with less waste material, even utilizes this asymmetric elbow mould.This displacement district 54 is formed at the crossing each district of elbow mould cup 31 of four adjacent positioned, as shown in Figure 5.If displacement district 54 is too large, thereby it is pressed against excessive raw face thin slice and on conveyer, forms the face of giving birth to and waste during being cut by rotary cutting die 30.Thereby the raw face being formed by displacement district 54 is wasted not to be baked and is formed biscuit and reduced output.Dough sheet is selected curvature 42,44, and the combination of angle 50 and surface area makes to carry out this nested arrangement.During cutting step, form the raw face amount of waste in order to minimize or to prevent, the nested pattern 74 of elbow mould cup 31 mentioned above and the top side 41 of elbow mould cup 31 and the curvature degree of bottom side 43 42 and 44 are for forming perforation at raw face thin slice.

The curvature degree 42 and 44 of top side 41 and bottom side 43 be respectively every side curvature measure and conventionally relevant with this side length.Can be by bending effective diameter (D take inch as unit), effective angle (to spend the A as unit), scan (sweep, to spend the S as unit) and bending arc length (take inch as the L of unit) limits this bending.In a kind of scheme, curvature degree 42 and curvature degree 44 are with about 1% to about 4% difference, and it can make each elbow mould cup 31 nested tightly with sinusoidal pattern 74., bottom side 43 has with respect to top side 41 curvature about 1% to about 4% scope curvature degree more closely.As shown in Fig. 7 and following table 1, acceptable curvature degree is limited by sample 2,3 and 4.The sample 1 and 5 of relatively flat and overbending does not have acceptable curvature degree because they and do not allow the nested arrangement 74 (such as sample 5) compared with less waste material unlike elbow (such as sample 1) or they.

Table 1: curvature degree

Find, curvature degree, and particularly between the top side of elbow and the asymmetric curvature degree of bottom side and die cavity wastage relevant.Between the top side of elbow and bottom side, the little difference of curvature degree forms nested arrangement effectively to produce compared with the blanking punch of less waste material.On the other hand, having the too elbow mould cup 31 of deep camber degree 42 and/or 44 can not closely nest together.Particularly, in the time using compared with deep camber degree 42 and 44, the raw face waste increase forming at 52 places of displacement district during rotating mould cutting.On the other hand, too little curvature degree does not form the dough sheet with elbow.

Go to Fig. 6, multiple blanking punch 36 are arranged to the wavy or sinusoidal pattern 74 around the circumferential surface 34 of cylinder 30.In fact, the two-dimensional pattern 74 of Fig. 6 is wrapped in around cylindrical tube 30 around, the surrounding's row 70 that makes blanking punch 36 around extend towards periphery in the week of cylinder 30 and the lateral rows 72 of blanking punch 36 on cylinder 30 horizontal or extending longitudinally.Each blanking punch 36 that limits elbow recess 35 closely nests together to form the surrounding's row 70 extending around cylinder 30 and makes the top side 41 of each blanking punch 36 adjacent nested with the bottom side 43 of adjacent blanking punch 36, and end 39 is adjacent one another are with formation lateral rows 72.Should be appreciated that when the two-dimensional pattern of Fig. 2 is during around the circumferential surface parcel of cylindrical tube, the bottom side 43 of topmost blanking punch 76 by be nested in the top side 41 of foot blanking punch 78, make blanking punch 36 continuously around row 70 form around the circumferential surface 34 of cylinder 10.This difference of top side 41 and bottom side 43 and asymmetric curvature degree make to carry out this nested.

Equally, lateral rows 72 on the surface of cylinder 30 laterally extending.Laterally adjacent blanking punch 36 relative to each other turns over turnback and makes blanking punch 36 alternately have top side 41 and the bottom side 43 of direction towards the opposite.Configuration like this, the lateral rows 72 of blanking punch 36 forms waveform or sinusoidal pattern.Lateral rows 72 should be above the raw face thin slice that advances on cylinder 30 at the laterally extending width that approaches as far as possible raw face chip edge the raw face wastage to reduce to form along rotary cutting die 31 edges.

After by circumgyration incision die cut, the dough sheet forming advances to baking box, and there, they are baked to form biscuit product.In a kind of scheme, the dough sheet forming is baked certain time and temperature to be enough to produce and to have about 2% biscuit to about 4% moisture.

As mentioned above, process as herein described is also configured to produce and has the biscuit of lower degree of crushing, such as lower than about 15% and be preferably lower than about 5%.Find the biscuit with this low degree of crushing that is combined to form of the raw face weight of each elbow dough sheet between about 0.7 gram and 0.8 gram and about 2% to about 3% raw face moisture.Have lower than the most lifelong face of the moisture of about 2% minimizing and produce rusk, it may not be filled whole die cavity 36 and therefore it has been generally acknowledged that due to the elbow shape not exclusively forming increases relevant with fragmentation.Or the most lifelong face that is greater than about 3% moisture produces too soft and block and do not form the raw face of even thin slice, it also tends to cause the not exclusively elbow of formation.

With raw face moisture combination, also determine that the raw face weight of each biscuit sheet is relevant with degree of crushing.For purpose of explanation, unless exceeded about 10% shape or weight does not exist, biscuit sheet is by for being complete (, broken).For example, weight is the biscuit that the most lifelong face of about 0.6 gram forms sheet and produce about 30% unacceptable high degree of crushing.Weight produces broken being significantly reduced to lower than about 15% and in some cases lower than about 5% biscuit at about 0.7 gram to about 0.8 gram and the moisture sheet between about 2% to about 3%.Along these rules, find that the surface area of each elbow is for fragmentation also outbalance.Preferred surface is amassed between about 0.6 to about 0.8 square inch.

Should be appreciated that as in the scope of the expressed principle of claims and implementation method, can be by those skilled in the art for for means of interpretation character, with the elbow biscuit forming and herein, details, material and the arrangement of description and illustrated process, formula and its composition make a variety of changes herein.
