Description

The method and apparatus of extruding and oven dry food made from wheat

The present invention and to the method and apparatus of extruding and oven dry food made from wheat, it belongs to the technical field of the wheaten food production line of the method that squeezes out that food made from wheat places on the whole width of drying unit and product is dried and this method of realization.

It is believed that, producing so-called elongated products, for example the method and apparatus of elongated noodles with produce so-called brachmorphy product, for example little ear or other cut into the wheaten food of weak point like this so that it may relate to another kind of method of producing pelletized product, method and apparatus between the principle difference is arranged.

That is to say that at industrial production elongated products elongated noodles all are to be caught with a rod by the wheaten food bar that mould provides continuously up to now, and cut at this bar place the length of regulation and thus the bar place send in the drying unit, at the drying unit place wheaten food bar is cut into the elongated noodles length of hope then.

When producing the brachmorphy product with known manner, the height of paying corresponding mechanical aspects expends, spend in and be used to admit and delivery element and the grass-hopper of sending into oven dry, but with respect to producing for example elongated noodles of elongated products is advantageous, that is this brachmorphy product just can cut to its finished product length at the extrusion die place.

Therefore, the object of the present invention is to provide and a kind ofly can produce the method and apparatus that the long dough product can be produced the brachmorphy food made from wheat again.

Solution of the present invention is: a kind of method of producing brachmorphy food made from wheat and long dough product, push and in a continuous dryer, dry subsequently by an extrusion die shaping, wherein be shaped and carry out on the whole width be squeezed in continuous dryer, food made from wheat is directly sent into the prebake district, and to be admitted to one then be on the plane of level substantially, dry to remain in the main baking zone, the brachmorphy food made from wheat is right after at extrusion molding apparatus and cuts in the prebake district, the long dough product cuts drying Hou wholly or in part, it is characterized in that, oven dry is carried out in a plurality of oven dry levels, each grade have one oneself, controlled weather manipulation device and oneself a air circulation device is respectively arranged, prebake is carried out under the food made from wheat temperature more than 70 ℃, and the main oven dry of food made from wheat is being carried out under 80 ℃ to 150 ℃ food made from wheat temperature.

And embodiment preferred is: a kind of food made from wheat production line that is used to implement said method, produces long dough product and brachmorphy food made from wheat, has the shaping extrusion die on a dryer that is designed to have the continuous drying district and the whole width that extends in dryer, it is characterized in that, connect one at the shaping extrusion die and have and the isolated prebake district of extraneous air and the dryer of main baking zone; Be provided with one is used for the cutter sweep of brachmorphy food made from wheat and long dough product and is provided with the cutter sweep that is used for the long dough product at the dryer back and the inter-stage thereof of main baking zone in the prebake district.

Say in principle, height expend with complicated technology solution very, they then are three-dimensional compactness and interesting therefrom on the other hand, so for a large-tonnage suitability for industrialized production producer is acceptable, but the little producer of food for a dispersion considers its condition restriction and management philosophy and relevant therewith reducing production costs, and makes technique scheme perhaps become too complicated and too expensive thing.

The tendency of technical development recent decades recently is the industry magnificenceization, but it seems that it has caused defective on all ecologies today, therefore just having produced a thought changes, that is from magnificenceization again to the target direction effort of small business, with allow to equally correspondingly reduce have transportation problem and ecological burden through pin mechanism.

Just for such consideration, the invention talent has proposed aforementioned invention task.

Under pure physics consideration situation, for example half an hour, interior baking finished food made from wheat.

The applicant's one first design quantum jump is exactly that the climatic environment of drying unit is regulated control completely with the section form, using bake out temperature for elongated products simultaneously is 80 ℃ to 100 ℃, and oven dry the time can be reduced to 2 to 6 hours, even can minimumly be reduced to one hour in the laboratory.But the oven dry skill that all experiment showed, is used for elongated products not only can cause many difficulties, but also can require special environmental condition.So in marketing, can only use the rod mode for the furnace drying method of long dough product.Use the oven dry scheme of not having rod for elongated products, owing to technical reason is not implement actually, because say in principle, technical measures must satisfy on the biology that the institute product processed proposes and laws and regulations requirement biologically and physically.

A target of food made from wheat oven dry is, the internal soundness that product is not only arranged, roughly as culinary art characteristic, mouth (for example: the tooth sense) or color sting texture, fracture strength (fragility) etc., and fully specifically also to make single elongated products have a rectilinear form as much as possible, especially for elongated noodles.For the latter, that is linear as much as possible, though the consumer to this require fewerly, it is a basic premise from the noiseless work of packing machine.

Being squeezed into of food made from wheat is afterwards crooked and deformable easily soon, therefore just can be suspended on the rod with simple measure and known U-shaped mode, and remain to the terminal oven dry in this position.In this way, if when in drying course abominable defective not taking place, people just can obtain long and food made from wheat straight line.

Like this, elongated products places the problem of drying on the rod to solve technically.

But just have a problem when improving bake out temperature, this moment is to the workpiece of operational outfit, and machinery, and particularly the member for mechanical movement has proposed obvious higher requirement, and then the cost that causes making a complete wheaten food production line improves.

Characteristics up to now are that producing short food made from wheat or brachmorphy product is very usual thing.

The brachmorphy product is the mould extruding by a circular face, and directly cut into desirable package length at the mould place with the cutter of a rotation, after cutting, this brachmorphy product drops on the conveying device at least, it is transported to product in the rotary distributor, this distributor is distributed to these products in the vibration prebake device, and forms a uniform dispersion layer on the oven dry surface.

After vibration prebake, this brachmorphy product has had a considerable shape stability, and like this, these products with big layer thickness are just dried on multi-form drying belt, are lower than 13% until finished product humidity.

In contrast, elongated products is not directly to cut at the mould place, but after the wheaten food bar is suspended on the rod with typical U-shaped, just according to special structural requirement, on about 0.5 to 1.5m the distance of extrusion die, to cut, therefore just can obtain a stable exchange space, promptly hang cutting or the like.Then, often be directly to do before the final package length cutting with dry products, this product rests on the rod.This product especially for the situation that the good stability requirement is arranged, stop many hours on the rod of stacking the storehouse, and it seems that this outside shape can only be forced to this special dry technology.So it is not imaginable drying for the mode of the unconsolidated formation of elongated products till order.

The present invention allows multiple favourable organization plan, like this, and food made from wheat for example, just can after final shaping, directly send in the climatic environment by control measure control, simultaneously, the temperature of product just can be heated to more than 70 ℃ from extrusion temperature, preferably more than 80 ℃.

Simultaneously, elongated products both can be as hot bar strip after a prebake, under at least 70 ℃ of situations, cut into oven dry length, perhaps also can cut into final products length, and the product of hot state one with the batch stoving process of knowing in oven dry or send into the oven dry of main drying unit.

Particularly preferred scheme is, the wheaten food bar oven dry that is used for elongated products is to enough dimensionally stable state and be lower than 28%, is preferably lower than 25% humidity, wetting and cutting, the product after should cutting then for example becomes a ground, do last oven dry, until the humidity that is lower than 13%.

When drying unit has the thermal treatment zone alternately and dries synchronic also is favourable scheme.Simultaneously, the heating of food made from wheat can be used hot-air, perhaps realizes with microwave energy, can carry out strong oven dry to each wheaten food bar according to this.

In another advantageous embodiment, food made from wheat is carried out the processing of stabilisation by microwave at the end of drying unit.

But, fully specifically, drying course is finished in several oven dry grading plants, each classification should have oneself a controllable climatic environment and regulate, and oneself air circulation system, suggestion simultaneously, the prebake of food made from wheat will be carried out from being higher than between 70 ℃ to 80 ℃ at product temperature.

Through evidence, the main drying course of food made from wheat can carry out under 80 ℃ to 150 ℃ temperature, and particularly preferred temperature is 90 ℃ to 125 ℃.

Ensuring the quality of products, be that product humidity is lower than 18%, particularly be lower than 15%, and the volume production of can not confronting is given birth to harmful side effect, particularly do not have under any venting bulge effect situation, bake out temperature can be brought up to 100 ℃ simply, so just can be implemented in beginning for the first time just has very fast drying effect and remains to the terminal oven dry, and therefore drying time can be reduced to so far can not be in the short time interval.

Heating problems can put on the product by microwave and/or hot-air and/or vapours and realize.

In another organization plan, during terminal oven dry, the product temperature classification also is reduced to and is lower than 60 ℃, and the heat that stores in product simultaneously is used to make water to become the state of steam state, and comes the heating, drying process according to this.

Use particularly the situation of heating using microwave wheaten food bar to utilize to be in obviously that low air bake out temperature carries out work, because along with the discharge of heat, also make the moisture content that is in steam state easily loose this moment.

Optimal way is, wheaten food bar (for elongated products) was finished whole line and flatly transported before cutting, and the oven dry air is vertically blown over this wheaten food bar, and air velocity can be controlled simultaneously, that is the adjusting of wheaten food bar remains on the flowability.

According to an other organization plan, at baking zone, the wheaten food bar is sent the auxiliary control of handling by one first product conveying device and a product at least, this product input unit is not apply collision and pulling force simultaneously, and the product carrying device is then adorned a slight pulling force and imposed on the wheaten food bar.In order not produce a bounce on the wheaten food bar, the length cutter sweep just should the speed with the wheaten food bar move when cutting so.

The present invention also allows multiple favourable organization plan, and preferably food made from wheat is directly sent into after final molding in the climatic environment by control measure control, and the temperature of product is heated to more than 70 ℃ from extrusion temperature, preferably is heated to more than 80 ℃.

For industrial production, a particularly advantageous scheme is that final moulding will so be finished, promptly form the wheaten food bar of a horizontal movement, it directly imports in a heating and the oven dry climatic environment, so just can avoid chill relatively wheaten food bar can bear bending force immediately after extruding effect.Therefore also possible is that very long leg piece is set, and for example in the situation of rod-type master drying unit, whole like this drying unit has just shortened, and can be arranged to the continuous oven of an individual layer.

According to the another one organization plan, should and the food bar can cut at an also moistening state, then dry aly.In another embodiment, this wheaten food bar does not cut and just advances to connect to dry the Stability Analysis of Structures state, cuts into package length again, the final oven dry in a then ground, and stable the processing deposited to packaging process in the vertical shaft storehouse.

According to the another one organization plan, these pastries are operations of level, and the oven dry air is vertically to carry transverse to this food made from wheat, the speed of air is preferably selected so high simultaneously, that is food made from wheat is adjusted on the flowability, and this food made from wheat is by a continuous conveying device, and preferably a ventilative endless apron or ventilative vibrating transportation unit are carried.

The present invention relates to a food made from wheat production line of producing long product in addition, have a pastries pressurizing unit and a continuous drying apparatus with the continuous conveying system that is used for food made from wheat, if when relating to long product, also has the length cutting machine that connects after.

In the complete particularly advantageous organization plan of another one, settle a wheaten food bar cutter sweep at the extrusion die place, it has cutting blade, and it has the vertical cut direction towards extrusion die.

This continuous drying apparatus can two-layer or sandwich construction setting.

Fully special favourable scheme is that this drying unit so is provided with, and it has a plurality of baking zones, and each district has independent controllable climatic environment adjusting device and air circulation device preferably with the air circulation device of turbine system.

The organization plan that another one is favourable is that this continuous conveying system part-structure at least has the vibrating transportation unit, and this unit preferably has longitudinal side wall with longitudinal guide food made from wheat bar.

In addition, this new invention also allows the special organization plan of a wonderful or complete series, and preferably, this cutter sweep is used a control device and done structure setting like this, that is cutting intermittently can be controlled.

Like this, for example corresponding to the drying course of wheaten food bar, this cutter sweep both can be applied to begin cutting, also can be applied to the terminal cutting.

Under the situation of brachmorphy product, the speed that this cutting intermittently must be come out from mould according to product and the product length of hope are selected.

In addition, this cutter sweep also can be arranged to transverse cuts device or two formula cutter sweep.Just can realize a linear cutting according to this with flank speed.

Also suggestion in addition, the length of extrusion die is roughly consistent with the available width dimensions of vibration drying device, simultaneously at the following scheme of the extrusion die product input unit of buying property, so that directly product is transported in the continuous drying apparatus.

This continuous drying apparatus can be provided with two or more backset beds at traffic direction, and they preferably can be arranged to the vibrating transportation unit, and this continuous drying apparatus is divided into a plurality of climatic environment districts with own air circulation system simultaneously.

In a further preferred embodiment, this continuous drying apparatus is a sandwich construction setting.

In addition, for the brachmorphy product can also, select a known drum-type drying unit as the terminal baker, connect back in continuous drying apparatus.

In addition, in a particularly advantageous organization plan, in the zone of terminal drying unit, a longitudinal cutter can be set, the package length that the food made from wheat sawing that is used for growing becomes to wish.Thus, this wheaten food production line with regard to structure with CH application case CH02292/91-8 (TW108) be provided with consistent, therefore can carry out to gamut reference.

Can a carrying device be installed before the length cutter sweep in addition, according to this, the brachmorphy product can directly cut at the extrusion die place and form, and has just sent from production line before by the length cutting machine.

The invention still further relates to the method for a production food made from wheat, simultaneously, this food made from wheat is squeezed into the wheaten food humidity of tool about 28% to 35%, dries and cut into the package length of hope.This food made from wheat can be passed through a vertical mould extrusion molding simultaneously, and dries in an infiltration type backset bed.

Wonderful mode is vertically to produce a real comprehensive effect between mould and the infiltration type backset bed, and wherein the extruded velocity of mould place product directly produces favorable influence to the seepage velocity that runs through backset bed.

Under the situation of brachmorphy product, just can on backset bed, produce a partition effect by the shake on the width, an automatic balanced action when changing, product quantity just can be arranged according to this.

In another preferred construction scheme, this food made from wheat forms by a vertical mould extruding with length cutter sweep, and in a through type drying unit, dry the package length of sending as the brachmorphy product and will cut into hope as elongated products by a length cutter sweep with the unconsolidated formation form.

Simultaneously for the brachmorphy product can also, the oven dry of product is lower than about 20% until toughness to be carried out in continuous drying apparatus, the terminal oven dry can be carried out in a rotating cylinder baker.

Represent a stationary level that is used for drying product with dash number 35.For stationary level, people's understanding be one after drying course to pastries cross section extexine implement moistening again, with a kind of fracture of generation avoiding after.

Sending end 36 places, this brachmorphy product has one and is lower than 13% wettability, and can then stack, and perhaps wires up immediately.

An elongated products production line of following the present invention design similar to Fig. 7 has been described in Fig. 8.Herein, at the beginning and the end of a functional class, this wheaten food bar cuts into a unified length by transverse cuts device 15.Yet package length just is made into by a cutter sweep 40 of being arranged to " basic labor front yard " herein in the exit of baker 8, is transported in container or the packing machine in the package length of sending in the mould 41 of stockpile.

Fig. 5 shows that the solution among Fig. 8 has the container stacking adapter 50 that connects after, then transfers device 51 by one as the product of the well cutting of package length and is sent to container stacking adapter 50, packs as required then.

The brachmorphy product can be as shown in Figure 6, in baker 8, only dried and be approximately 20% humidity value to dimensionally stable, send into then in the drum-type baker 16, it discloses in the application case of an European patent communique Nr0142652 and has described, in this baker 16, finally dry on the storage humidity.

In addition, the possible scheme that also has is, in a baker 8 or 31,31.1, settle a stacking adapter 50 that is applicable to elongated products or brachmorphy product line 31.2 locate to connect, simultaneously, the brachmorphy product is corresponding to the arrow among Fig. 1 16, these products vertically are being sent before the cutter sweep 40, in order that can be left in the brachmorphy product piling device with container stacking adapter 50 arranged parallel.

But, have only brachmorphy product that part dried by the fire in a drum-type baker 60 with container stacking adapter 50 arranged parallel, to do last oven dry.

The advantage of food made from wheat production line of the present invention is, under suitable selection production capacity and suitable climatic environment, uses identical baker and just can make elongated products or brachmorphy product, and this just allows, and an overall product facility is realized best operation.

In the another one structural design scheme, can also in the terminal drying course, product temperature is dropped to hierarchical approaches be lower than 60 ℃, and the stabilization process of food made from wheat realize by microwave method.

The type of this drying unit and mode, as they Figure 10 with have in 11 shown in the circulating air system the same, in the application case of an European patent communique Nr012989261, disclose and described, and be called in the commerce and trade of eddy current heat enginnering " TURBOTHEMATIK " known in name.Therefore, every circulating air system that relates to just sees also disclosed patent gazette or its application text.

Fig. 9 has represented a part of eddy current baker 31 shown in Fig. 7 and 8 or 31.1 and 31.2 in the amplification mode, wherein, the vibration material delivering groove, as representing in conjunction with Figure 10 later on, be that elastic type is settled, therefore, by the vibrating elements on the vibra shoot 101 102, just give 101 1 of vibration material delivering grooves along the moving of arrow S direction, like this, product just is sent in this vibration material delivering groove along throughput direction V.

In addition, as Figure 10 and 11 described, can produce the air stream with arrow 34 signs, like this, the product (food made from wheat) that is arranged in vibration material delivering groove 101 is just by this air circulation mistake, and therefore is dried.Product moves in the lift of S direction by vibrating elements 102 along transporting of direction V and realizes that because like this, product has also just produced along the jumping of V direction.

In order to make product the vibration material delivering groove that the separation point position connects after a vibration material delivering groove is sent to the next one, the angle that it is α that each feeding groove all has an acclivitous horizontal relatively H, this angle α is that experience is determined, but has only the number of degrees seldom in general.

This separation point position is at horizontal dividing wall 100 places, though it allows product to deliver to another from a vibration material delivering groove, but, say from air flow technique, it is basically with zone C, and D and E and F are separated from one another to come, like this, the air circulation system of representing by Figure 11 in each district in each corresponding arrangement in district just can be set up oneself a air circulation.

This vibrating elements 102 is arranged on the groove frame 105, the ccontaining bottom land with holes 106 of this groove frame.

As can be seen from Figure 10, this groove frame 105 flexibly is bearing on the supporting member 109 by compression spring 110, so that allow above-mentioned lift along the S direction.

This foregoing vertical guiding device is to represent with the dotted line 130 that draws.

May enter dead-space volume for fear of pollutant and dust, this groove frame vertically separates wall 112 by the seal 107 of a flexibility and eddy current baker one on the one hand and is connected, seal 108 by a flexibility is connected with aforesaid supporting member 109 on the other hand, and supporting member 109 self is fixed on vertical wall 112.

Below bottom land with holes 106, will 111 be fixed on the supporting member 109 at the bottom of the admittance with holes.

At last, the eddy current baker respectively is provided with a heating element heater 11 in order to the heat cycles air in side chamber 123, also respectively be provided with a circulating air blower fan 10.
