Yerfahren and apparatus for producing a partially on the inside "coated hollow pastry

Field of application of the invention;

The invention relates to a Yerfahren and apparatus for producing an at least partially coated on the inside and optionally at least partially filled hollow pastry, wherein a pastry band, in particular a baking soft waffle tape, continuously wrapped in a helical overlap over a Born to an endless sleeve-shaped rotating body and the latter on his Inner side coated with a suitable mass for human consumption and is divided into individual pieces of certain length, wherein the BeSchichtungsmasse supplied by the mandrel towards the free end and is applied in the same area on the inside of the sleeve-shaped body.

Characteristic of the known technical solutions

From the food and beverage industry, among other things, various machine-made, ¥ affeiprodukta are known, - which come filled or unfilled in the trade. "These products of the wafer industry are -z," B. wafer cones, wafer cups, wafer plates, flat waffle slices, lower hollow waffles, hollow sticks, waffle rolls, sistüten, filled waffles, ice cream waffles, small stuffed T / affelstangen, Waffelschnitten and the like, more. These waffle products are waffle-dough baked products of crispy, brittle, fast and easily breakable consistency, which are baked as dry as possible and have a very low moisture content.

The different types of waffle products can be made in different ways. For example, some waffle products are "baked in their final shape, as is the case with waffle bags, wafer cups, waffle slices, low hollow waffles, and the like."

In the production of others. Waffle products are first baked in a waffle sheet or endless waffle band and, in the still baked state, shaped into the final shape, in which the wafer product cools and assumes its crispy, brittle consistency. Examples of this are sugar ice sticks, hollow sticks, sugar Called Waffelröllchen and the like ..

For the production of other types of waffle products, several wafers are baked, chilled, creamed, and stacked into a waffle block. This cream-filled waffle block is then cut into small, equally sized handy pieces that. then packaged in units consisting of one or more pieces, possibly also packed airtight in the trade «

Depending on the product, the various waffle products may be provided with coatings, such as sugar or chocolate, or with various fillings, e.g. Ice cream, various creams, chocolates, or the like. Be filled. These waffle products just described are to be distinguished from those waffles which are usually baked by the housewife in waffle iron and which are white

These waffle-made wafers have no similarity in their consistency and usability with the waffle industry waffle products described above.AiE-PS 262 187 discloses a sleeve-like waffle body by winding a waffle body into a waffle To produce still hot plastic state wafer band, the supplied by a continuous Waffelbachmaschine waffle belt is continuously wound helically over a winding mandrel to an endless sleeve-shaped body which turned as a result of Wickeins The fixed or rotatably mounted and driven winding mandrel is provided with a longitudinal bore which narrows at the free end of the /eldornorns at the mouth to a spray nozzle through which Pett or chocolate is sprayed onto the inner wall of the sleeve-shaped body · Hach the hardening de s sleeve-shaped body on the sprayed substance this is sawed by means of a circular saw. In this known method, only sprayable or by heating sprayable made 'substances can be used. In this case, a transport medium, z. Air is required to achieve a fine distribution of the sprayed substance * If the fat to be applied or the chocolate to be applied are liquefied by heating in order to make them sprayable, there is a risk of overheating of the fat or chocolate the liquefaction of the same limited by heating, so that also here for Sprühfähigmachen air must be added as' transport medium. It has proven to be disadvantageous that the amount that can be applied by spraying is limited by the fact that the

A 21 C / 243 041/6 61 337/23

could not escape air from the wound waffle body during the cutting process without destroying the waffle body itself. " A liquefaction of substances by dissolution in a solvent or by mixing with other liquids, with the aim of making the respective substance sprayable, is impossible because 3a only the respective substance sticks to the inside of the sleeve-shaped body, if das.Lösungsmittel or the carrier liquid for the substance either evaporate or can be absorbed by the waffle body itself. For. the evaporation of the solvent or the carrier liquid is far too small for the hollow space present in the interior of the waffle body, or the time available until the sleeve-shaped body is severed is not sufficient to absorb the solvent or the carrier liquid the waffle body itself is completely ruled out because this would lead to a destruction of the waffle body. Furthermore, when spraying grease or chocolate onto the inside of the sleeve-shaped wafer body, it is disadvantageous that the spraying results in complete atomisation of the cavity of the endless sleeve-shaped wafer body, and the malodor contaminates the circular saw used to sever the body, so that it will over time is functional and therefore must be cleaned frequently, resulting in an interruption of the manufacturing process of the waffle body. In addition, the lever formed between the singeing operations exits the interior of the waffle body into the environment and leads to pollution of the entire environment. "

Another disadvantage when spraying the coating material is that only a single coating material can be applied. If the sleeve-like waffle body produced by this known method are to be filled, then this is possible only after the sawing of the endless sleeve-shaped body into individual pieces,. since only then an introduction of the hill mass in the individual tubular waffle body is possible without danger. The subsequent filling of the individual sleeve-like waffle body requires a high manipulation effort, since the individual pieces collected after sawing in a suitable manner and a separate / dedicated filling / / fed Need to become·

From AI-PS 304 245 it is known to produce a filled pancake with a sleeve-like waffle body in which a wafer belt is still wound backwards soft state over a winding mandrel continuously helically overlapping to an endless sleeve-shaped body, via a longitudinal bore in the winding mandrel with a cream-like substance completely filled and before the hardening of the substance or the. sleeve-shaped body itself in desired lengths: sheared off. For lateral sealing of the sleeve-shaped body, the individual turns of the wafer band are applied to the overlapping surfaces of the overlap with steam, so that they stick together or are welded together under pressure. The waffle leaf used contains between 30 and 60 % of sugars, glucose or malt preparations, which are rapidly dissolved by exposure to moist heat.

go and sticky. In this known hollow pastry no coating on the inside of the tubular waffle body is provided, so that only those can be provided as filling compounds that do not soften the waffle band and thereby affect the strength and quality of the waffle body.

Since the filling of the known hollow pastry takes place immediately after the winding of the wafer band, namely through the winding mandrel, a coating of the wound.hülsen-, shaped body prior to filling the same, for. B. to install an insulating layer between filler and waffle body, completely excluded.

From AT-PS 327 129, a device for producing a hollow pastry for receiving a soft filling compound is known, wherein a pastry tape on one side with an insulating against the filling material layer, such. 3- chocolate and wound with this layer inward over a winding mandrel continuously helically overlapping wound to form an endless sleeve-shaped body. As a result, the pastry band windings are glued together in the overlapping areas by the chocolate layer. The insulating layer is applied by spraying or spraying or pouring onto the biscuit band. In the resulting hollow pastry, the filling material is introduced through the central longitudinal bore of the winding mandrel. In this device too, the selection of the masses which can be applied to the biscuit band is essentially spray-on or "spray-on" at room temperature. pourable substances or by heating in this state

restricted substances. In this known device, although it is possible that the added to Sprühfähigmachen or Spritabähigmachen air can escape and that melted by heat masses must be heated only to the extent that they are pourable, but the applied masses must still be so elastic after application in that they adhere to the biscuit band during the subsequent winding of the biscuit band or, with the curvature of the biscuit band, can become deformed. Furthermore, these substances must retain sufficient adhesiveness during winding of the biscuit band to adhere to the outside of the biscuit band . Further , the applied substance itself must maintain the tightness of the insulating layer at the compression of the layer caused by the winding operation. This happens when liquefiable by heat substances, for example, by the contact with the outside of the still-warm pastry tape, if the temperature of the pastry tape is sufficient.

The use of substances which are not sprayable, pourable or pourable even at the working temperature of the winding device, or, by the contact "melt with the pastry tape, are not suitable for this type of application of a coating

presentation; the essence of the invention

The invention is based on the object, an at least partially coated on the inside and optionally at least partially filled pancake, wherein a pastry band, in particular a baking soft waffle tape, continuously wound over a mandrel helically overlapping to form an endless sleeve-shaped rotating body and the latter on its inside is coated with a composition suitable for human consumption and cut into individual pieces of specific length, the coating composition being fed through the dome towards its free end and applied in the region of the same to the inside of the sleeve-shaped body, Any undesirable impairment of the cavity of the sleeve-shaped body or, the separator is avoided, in addition to liquid substances, such masses can be applied, which are not liquefied by heat and the distribution the masses on the inside of the bobbin necessary forces to cause no adverse effect on the bobbin «.

According to the invention, this is achieved by depositing one or more masses in the pasty or liquid or spreadable state on the inside of the sleeve-shaped body through one or more openings provided on the front side or in the conveying direction of the sleeve-shaped body behind the mandrel end and / or by means of a or a plurality of openings provided on the circumference of the mandrel or »in the transition region from the end face to the circumference of the mandrel, and if appropriate the mass (s) after etching

is distributed on the inside over at least a part thereof, and optionally after, the application of the mass (s) on the latter to be applied Rieselgut and / or introduced into the sleeve-shaped body through the mandrel or by a 3? Dorns is fed ·

The inventive method any untoward impairing the Hohlraumes.des sleeve-shaped body or _o the separator avoided because there is no atomization of the applied masses and thus no doweling the I nn enraumes the sleeve-shaped body "Furthermore, with the inventive method in addition to liquid even those masses are applied substances that are not liquefied by heat exposure ",, If the novel process substances applied to the pastry band whose melting point is above the temperature of G _e bäckbandes during the winding process, these substances need only so far heated be that they are just viscous when applied. The application according to the invention is further supported by the fact that the mass is distributed after impact on the inside »By distributing the applied mass an intimate contact of the same scored with the pastry tape

The consistency of the mass to be distributed is just chosen so that the forces necessary for distributing on the inside of the bobbin to cause no adverse effect on the bobbin _o

Furthermore, after the application of a mass to the inner wall of the sleeve-shaped body a Rieselgut applied

become". This Rieselgut is applied through the mandrel on the example still sticky Beschichtungsmaase, thereby'die surface roughness of the inside of the coated sleeve-shaped body is increased., Whereby a subsequently introduced filling compound in the hollow pastry has a better grip. As granular Rieselgut preferably granulated sugar, .Krokant, grated lasse or crispy rice can be used. But also powdered Riesegut such as icing sugar, or the like can be applied to the coating composition.

Furthermore, by the inventive method, the filling material can be introduced through the mandrel itself in the interior of the hiilsenförmigen body, before this is cut into individual pieces, with a necessary insulating separating layer between pastry tape and filling compound is already applied to the inside of the sleeve-shaped body «Beim Separation of the individual pieces of the endless sleeve-shaped body is immediately obtained a finished inside coated and filled pancakes, which are only packed to measure «

By coating the already greasy wound sleeve-shaped body, the positional fixation of the wound pastry tape in the case of a wafer band by welding the same, for example, by steaming the overlapping areas of the tape turns done, so that the internally applied mass so high demands must be made, as this z. B, while co-winding a layer applied to the biscuit band is necessary. "In addition, it allows

the method according to the invention of limiting the amount of coating agent applied to the extent absolutely necessary for insulation «

According to a variant of the method, the mass of the mass (s) emerging from the end face of the mandrel or in the conveying direction of the sleeve-shaped body behind the mandrel end is deposited essentially only under the effect of gravity. This variant of the method is particularly advantageous in the case of liquid or easily liquefiable substances, avoiding splattering or "spraying of the masses".

According to another variant of the method, the ^v mass (s) is / are discharged by the opening (s) provided at the circumference of the mandrel under a pressure such that a transient radial expansion of the sleeve-shaped body is at least approximately the same Strength of the layer to be applied is achieved «This can be applied on the one hand also Hasse, which is only spreadable or« pasty and therefore requires a relatively high discharge pressure and on the other hand, a regulation of the thickness of the applied layer by simply changing the discharge pressure and thus discharge pressure brought about become"

By applying one or more masses, the inside of the sleeve-shaped body is completely covered partially or with one or more continuous layers. The or, each of the layers is made up of several. Mass educated
