Description

Grill and roasting process

[Ol] The invention relates to a continuous grilling with at least two at least one

Grill gap forming grill rolls and a method for frying Grillgut on such a grille.

[02] Generic grills or roasting methods are known, for example, from EP 0 092046

AI, from DE 82 11 327 Ul, from DE 81 19 752 Ul, from DE 38 02 345 Cl, from DE 37 27 679 AI, from EP 0 053 656 AI or DE 38 16 474 Cl known and have a grill gap, which is traversed by grilling, which, as it passes through the grill gap, is grilled.

[03] In this case, the grills often include grill rollers, which serve the transport or the leadership of the grill, these grilles - depending on the specific design of the grilling - driven or mitlaufend trained may be. Likewise, these grill rollers, depending on the specific configuration of the grille, be heated, which may preferably be done by a arranged in the interior of the respective grill rollers heating.

[04] However, such barbecues do not seem to be marketable at the moment as they have completely disappeared from the market.

[05] It is an object of the present invention to design a conveyor grille with at least two grilling rollers forming at least one grilling gap and a method for frying grilling products on such a grilling conveyor in such a way that their marketability is increased.

[06] The invention is based on the basic knowledge that the marketability of continuous grills can be increased if this or a corresponding frying process achieves good frying results, even with different grilling products.

[07] The object of the invention is by Durchlaufgrills or roasting with the

Characteristics of the independent claims solved. Further, possibly also independent thereof, advantageous embodiments can be found in the subclaims and the following description. [08] Thus, a grille with at least two, preferably three, at least one grill gap forming grill rollers are characterized in that arranged between at least one of the grill rollers and a protruding and / or projecting into this, rotatable relative to this grill roller assembly an inner pivot bearing or that the passage grill comprises a relative to at least one of the grill rollers rotatable assembly which protrudes from this grill roll and / or projects into this, wherein between this grill roll and this assembly, an inner pivot bearing is arranged. The inner pivot bearing can in this case, with a suitable design, allow exact positioning of the rotatable relative to the grill assembly, which can accordingly specify the effect of this assembly, so that the flow grill with suitable control precisely different grill food can adapt, which ultimately increases its marketability.

[09] In particular, it is conceivable to provide an inner rotary bearing at both ends of the corresponding grill roll, which can serve to position this assembly as well as possible in relation to the grill roll. It is understood that, if appropriate, different assemblies may also be provided at each of the ends of the grill roller, which protrude into the grill roll or protrude from this and are stored accordingly.

Alternatively or cumulatively thereto, a grille with at least two, preferably three, at least one grill gap forming grill rollers characterized in that the grille comprises a relative to at least one of the grill rollers rotatable assembly which protrudes from this grill roll and / or in this protrudes, said assembly is mounted on a housing of the continuous grille or on a stationary relative to the housing mounted carrier group. Also, by such a carrier group, similar to the inner pivot bearing, with a suitable design, an exact positioning of the rotatable relative to the grill roll assembly, which can accordingly specify the effect of this assembly, so that the flow grill with suitable control precisely different grill food can adapt, which ultimately increased its marketability.

The exact positioning is, for example, in co-rotating with the grill role

Assemblies hardly feasible, since the corresponding assembly then rotates with the grill roller and not exactly positioned with respect to the grill or food.

The corresponding module can, for example, a heater and / or a

Include thermometer, where appropriate, the corresponding assembly may also include a support member for the heating or the thermometer. Likewise, the assembly may be a carrier element for other components to be positioned within the corresponding grill roll.

The support group, which can then carry, for example, the above-mentioned subassemblies, such as the heating and / or the thermometer or the carrier element, may be in particular a headband or arm, since such a headband or arm easily attached and with other fasteners for example, for the assembly can be provided.

[14] A very good positioning of the corresponding grill role in relation to the

Grill gap or in relation to the rest of the grille can be ensured that a corresponding grill role is rotatably mounted on an outer pivot bearing on a housing of the grilling. Also, such an outer pivot bearing may be provided in particular at both ends of the at least one grill rollers. Naturally, an outer grill bearing is provided with a relatively large diameter, so that it can better face large moments, such as, for example, possible overturning moments, than with a smaller diameter. In this respect, this can increase the stability of the corresponding overall arrangement.

When using an outer pivot bearing can then be stored on the inner pivot bearing on the rotatable relative to the grill role and protruding into this or protruding from this assembly on the inner pivot bearing, so that further holding forces, which for accurate positioning of this assembly yet necessary to be kept to a minimum. Such holding forces, for example, then serve to select the rotational position of the modules with respect to the grill role and to keep this assembly, for example, relative to the rotating grill role with respect to the housing, for which - of course - can also serve the carrier group described above.

On the other hand, it is also conceivable, the projecting out of the grill role and / or projecting in this, rotatable relative to this grill roll assembly relatively rigidly connected to the housing of the grille or perform a corresponding support group relatively stable, so that essential bearing forces for the grill role be provided via the inner pivot bearing, which accordingly relieves an outer pivot bearing - or also makes it possible to dispense with an outer pivot bearing. Instead, then, for example, only a seal or even only a sealing gap can be provided, which Accordingly, any cleaning work, which could occur in particular when changing the frying, for example, between fish and meat, reduced to a minimum.

Preferably, at least one of the rotary bearings is a plain bearing, it being understood that instead of a plain bearing, rolling bearings may optionally be used as pivot bearings. Under the given circumstances, in particular with regard to the robustness and the stability even with temperature fluctuations, as they naturally occur in a continuous grille, however, plain bearings appear to be correspondingly advantageous.

Preferably, the storage takes place via an insulation. This way you can

Transfer of any heat between the corresponding grill roll, which are reduced in the grill role in or protruding assembly and the rest of the grill to a minimum, which is particularly advantageous if the projecting into the grill role or protruding assembly includes a heater, in order to reduce the heat load on the rest of the grill and in particular any camps, or if the in the grill role protruding or assembly is to be protected from heat, for example by the grill roll or by any other means provided heating from heat.

The insulation can be realized in particular via an insulating layer, in this regard, other measures, such as insulating sleeves or point contacts can be used accordingly.

[20] Also, a grille with at least two, preferably three, at least one grill gap forming grill rollers can be characterized by at least one arranged within at least one of the grill rollers, a heating cartridge comprehensive heating. In the present context, a heating cartridge, a self-contained arrangement with two electrical connections through which a heating current can be passed through the heating cartridge, which can be prefabricated and positioned as desired in a compact and inherently stable unit. The use of a heating element has the advantage that it can be positioned relatively precisely within the respective grill roller, so that it can be ensured that good frying results can be achieved even with different grilling products, which accordingly increases the marketability. In a suitable embodiment, such heating cartridges also facilitate the maintenance activities, since the heating cartridge are relatively insensitive and can be handled easily and reliable. In particular, the fact that heating cartridges in usually have the electrical connections on one side, the control of the immersion heater, since all electrical connections must be provided only on one side.

[21] The use of a heating cartridge is in itself advantageous regardless of the other features of the present invention. However, the inner rotary bearing or the support group allow a correspondingly accurate positioning of the heating cartridge, so that in particular the connection with one or both of these approaches is cumulative advantageous. In a suitable embodiment, there is also the advantage that the electrical connections of the heating cartridge, especially since they need to transmit a relatively high power, not necessarily have to run on sliding contacts.

[22] Preferably, the heating cartridge is less than half the inner radius of the grill roller, in which the heating element is arranged, spaced from the grill roller. This increases the possible heat transfer to the grill role accordingly. Depending on the concrete implementation of the present invention, this distance can be provided only at one point, which accordingly leads to a punctual or to a local heating of the grill role, if this is desired. Preferably, however, the corresponding distance is at least in a portion of the grill role that is to be loaded with food to be grilled, in the section perpendicular to the axis of rotation of the grill role equal or varied below five percent. As a result, a correspondingly uniform heating of the grill roller can then be ensured.

Preferably, the heating cartridge is less than 10% of the inner radius of the grill roll, in particular less than 8% of the inner radius of the grill roll, spaced from the grill roll.

[24] In particular, in order to ensure a uniform heating of the grill roll, a continuous annular gap between the grill roll and the heating cartridge may be arranged, which is preferably continuously free and preferably varies less than 5% in its gap spacing.

Preferably, the heating cartridge is made of cast aluminum, which in particular ensures a very uniform heating of the heating element. It is understood that the use of such a heating cartridge is also independent of the other features of the present invention for the heating within a grill role of a continuous grille accordingly advantageous.

In order to achieve good frying results even with different grilled food, a continuous grille with at least two, preferably three, at least one grill gap forming Grill rollers cumulatively or alternatively to the other features of the present invention characterized by at least one arranged within one of the grill rollers electrically formed thermometer. Such a trained thermometer allows a very good and accurate detection of the respective temperature, so that a correspondingly good measurement result of a more accurate control of a heater or the rotational speed of the grill rollers of the grille can serve, which accordingly allows adaptation to different grilled food and its different physical properties.

[27] Good frying results can also be achieved with different grilling products when a grilling with at least two, preferably three, at least one grill gap forming grill rollers cumulative or alternatively to the other features of the present invention by at least one arranged within a grill rolls locally measuring thermometer distinguished. Accordingly, such a locally measuring thermometer allows the detection of the temperature locally at a location, which leads to correspondingly more accurate results, which is not possible by integrating temperature measurement, as this example, expansion rods.

Thermometers are particularly suitable resistance thermometers or thermocouples, which may be formed in particular relatively small and can measure with high precision.

[29] Also, the thermometer can be a thermo-sensitive color change area on a

Include the inner wall of the grill roll. Such color change areas are known, for example, from frying pans or electric grills and indicate to a viewer by their color change when a certain temperature threshold is exceeded or fallen short of.

In the interior of the grill role, for example, via a color sensor such

Color change determined and used for the temperature measurement.

The measurement result of the thermometer can be used on the one hand to control the heating or the rotational speed of the grill rolls to operate the conveyor grille at a desired temperature can. Likewise, the measurement result can be used for other purposes, such as the display to a user that the operating temperature has been reached or has fallen below a cleaning temperature, from which cleaning is easily possible. In this way, a temperature-related damage to cleaning agents, be they of chemical or biological nature or these mechanical cleaning agents, be reduced to a minimum. [32] In order to achieve good frying results even with different grilled food, a grilling with at least two, preferably three, at least one grill gap forming grill rollers can be characterized by at least one arranged within at least one grill rolls locally effective heating. In this way, the place where then the corresponding grill role is heated, are individually specified, so that optimum heating results can be achieved for different grill good. In particular, a plurality of such locally effective heaters may be provided, so that the locations of the heating can be adjusted individually in which certain heaters are switched on or off or operated at different temperatures.

[33] Good roasting results can also be achieved with different grilling products if a continuous grilling with at least two, preferably three, at least one grill gap-forming grill rolls is characterized by at least one controllable heater arranged within at least one of the grill rolls. In deviations from heating systems in which the heating power can only be switched on or off, a controllable heating system allows the temperatures to be much finer and to be adjusted to the particular food being fried.

[34] It is understood that the aforementioned advantages do not always have to be implemented, in which case it may be necessary to dispense with corresponding advantages. On the other hand, it is understood that the locally effective and / or the controllable heating can also be used in combination with the other features of the present invention, which applies in particular to an electrically formed and / or locally measuring thermometer.

Thus, the locally effective heating may have a plurality of heating elements or an eccentric with respect to the respective grill roll arranged heating element, which can be realized in a structurally simple manner targeted local warming of the respective grill role.

As already explained above, it is advantageous if the heating cartridge off

Cast aluminum is formed, resulting in an excellent uniform temperature distribution on the surface of the heating cartridge, so that it can be used locally effective targeted.

In particular, an electrically trained thermometer allows in

Interplay with a controllable heating a very good and accurate temperature control of the heater and, accordingly, any grill rolls or or a very precise thermal load on the grill or roast. This applies in particular if different grill or grilled food should be grilled or fried, for example, fish or poultry better grilled or fried at other temperatures such as pork or beef.

[38] In particular, the thermometer can be mounted on or in the heater so that the temperature of the heater can be measured very accurately and possibly also regulated. Depending on specific requirements, the thermometer on the surface of the heater, so that in some ways can measure the temperature of the grill roll, or poured into the interior of the heater, for example, in the heating element, so that the temperature of the heater can be detected very accurately can be arranged.

[39] The heating cartridge may have a respective bearing point, in particular at its ends, so that it can be reliably and precisely positioned relative to the respective grill roller. In this case, the bearing points can cooperate with the rotary bearings explained above and / or with the carrier groups described above. Preferably, the heating cartridges had only at one of their ends one or more electrical connections, such as for a power supply and -abfuhr or for one or more thermometers. This allows all associated components, such as a power supply, any electronics for the operation of the thermometer, a possible control or regulating device can be arranged only on one side of the grill rollers or the grill gap, and can be dispensed complex cable guides.

[40] With different grilling good frying results can be achieved independently of the other features of the present invention furthermore, if a grille with at least two, preferably three, at least one grill gap forming grill rollers by at least one coated with a non-stick coating or enamelled grill role. As a result, residues of grilled food remain to a reduced extent or hardly on the grill role, so that different grilled food can go through the grille without a relatively large effort in a row with good frying results. Also, a corresponding non-stick coating or enamelling that the respective grill role can be cleaned quickly and easily.

[41] The non-stick coating may comprise in particular a Teflon ^® coating, which is especially established with respect to the prior art with regard to a non-stick coating. In particular, the Teflon ^® coating may have a color indicator such as this is already known from the prior art for frying pans or electric grills. On the one hand, such a color indicator can already indicate to the user's eye, if one certain temperature, for example, a sufficiently high grill temperature or a sufficiently low cleaning temperature is reached. Likewise, it is conceivable, on the other hand, to monitor such a color indicator via a color sensor, so that corresponding information can be acquired by measurement and made available for electronic or processor-based further processing.

[42] On the one hand, color change systems can be used as a color indicator, changing only between two colors. Likewise, however, color indicators are known which undergo a color spectrum as a function of the temperature.

It is understood that a corresponding non-stick coating can also be used in particular cumulatively to the other features of the present invention, and this in particular with a color sensor and any cleaning methods.

[44] Also, a grille with at least two, preferably three, at least one grill gap forming grill rollers can be characterized by means for monitoring the grill gap in order to achieve good frying results with different grilling. Such monitoring means can be used to draw conclusions about the presence of grilled food or on its consistency or nature. For example, such monitoring means may comprise a torque detection which detects a change in the torque on the grill rollers and draws appropriate conclusions due to this change. Thus, for example, the torque change can immediately suggest clues to the presence of food or its absence, so that in this regard the temperature behavior can be controlled accordingly. Also, a change in the torque conclusions on the thickness of the Grillguts give, since - naturally - thicker grilled food at the same grill gap causes increased torque. The monitoring means may moreover comprise an ultrasonic sensor which on the one hand can directly measure the presence of food to be grilled or certain material properties. Cumulatively or alternatively, the monitoring means may comprise a pressure sensor which can measure a certain pressure on the grill rolls or on at least one grill roll and in this way can close the presence or absence of grill food or its thickness. Preferably, at least one of the sensors of the monitoring means is designed as a proximity sensor, so that the presence of food to be grilled, which is to enter the grill gap, detected as early as possible and possibly a temperature adjustment of the grille can already be made preventative. [45] It is understood that such monitoring means may be used cumulatively or alternatively to the other features of the present invention. In particular, in conjunction with a speed control and / or a temperature control for the grill rolls cumulative benefits can be achieved here.

[46] If a continuous grilling with at least two, preferably three, at least one grill gap forming grill roles by at least one grill role with different diameters, can be achieved with different grilling, especially if this has different strengths, each good frying results. By a grill roller with different diameters different gap strengths of the grill gap can be provided in a structurally simple manner, so that thicker food can be introduced into an area with a wider grill gap, while thinner food can be introduced into a gap with a narrower diameter. In this way, in each case correspondingly good frying results can be achieved with different thicknesses of the grill.

[47] A grill role with different diameters, for example, can be conical, but this is structurally relatively complex to implement, especially since the different rotational speeds, which are caused by the respective different radii, lead to uncontrolled forces on the food. Also, the gradual change of the grill roll diameter causes a piece of the food to be grilled in a changed grill gap on one side with a narrow diameter and on the other side with a larger diameter. In this respect, it is advantageous if the different diameter having grill roller has at least two sub-rollers with different diameters, these sub-rollers are each cylindrical in a preferred embodiment, so also correspondingly over a certain length of the grill gap, namely the length of the corresponding sub-role, a constant gap diameter for the grilled food is available. In this way, in each case a good frying result can be achieved in a structurally particularly simple way with different grilled food.

It is understood that a grill roll of different diameters both independently of the other features of the present invention as well as in combination with the same is correspondingly advantageous.

[49] In order to be able to achieve good frying results with different types of grilled food, it is advantageous if the grilling grate comprises electronics through which For example, a grill roller drive or a heater can be controlled in each case adapted to the different Grillgut. However, the electronics may also only serve, if necessary, to ensure a particular uniform running of the grill roller drive or to control a heating of the conveyor grille in the desired manner.

However, it has been found that such electronics is relatively sensitive to temperature, so that it proves to be advantageous when a grille with at least two, preferably three, at least one grill gap forming grill rolls through a split housing, in a part of housing at least one grill roller drive, in particular a motor, and in the other sub-housing at least electronics are arranged, characterized in order to achieve good frying results with different grilling.

Even the housing separation makes it possible to reduce the temperature load on the electronics, which is particularly easy to implement when the sub-housing in which the electronics is arranged as far away from the grill rollers is located.

[52] It is understood that the housing, if necessary, further sub-housing, such as a

Housing for the grill rolls, may have. In a particularly preferred arrangement, the sub-housing is arranged in which the grill roller drive, the delimitation and thus the isolation of the sub-housing in which the electronics is arranged to the grill rolls.

[53] Further thermal relief can be achieved by the already explained above

Achieve insulation. Also, each provided on one side of a heating element electrical connections are advantageous here, since then measures must be provided for thermal insulation only on the appropriate side of the housing.

It is understood that the division of the housing into sub-housing is also advantageous independently of the other features, in particular, a combination with the other solutions described here brings corresponding cumulative benefits.

[55] Accordingly, it is advantageous if at least one of the sub-housings is cooled. Although relatively complex cooling mechanisms, such as cooling coils or a Peltier cooling can be provided here if necessary. Particularly structurally simple, however, air cooling, which may be caused in particular by a fan. [56] In order to reduce any odors to a minimum, which could possibly also lead to changes in taste with different grilled food, a grille with at least two, preferably three at least one grill gap forming grill rollers cumulatively or alternatively to characterize the remaining features of the present invention by at least one suction gripping the grilling gap.

[57] Here, the suction can be arranged for example inside the housing and suck in this way according to odors and flying brats from the grill gap. The suction can then easily detect from the inside of the housing out of the grill gap.

[58] Preferably, the housing is closed except for an inlet leading into the grill gap and outgoing from the grill gap, so that an occurrence of residual air is reduced to a minimum and the suction can effectively capture the grill gap.

Preferably, the suction is in this case dimensioned such that a sufficient

Air flow through the entrance and the exit into the housing, taking into account any leaks in the housing, such as by slots between cover plates, micro-openings in the range of threads or rivets or the like, can be ensured.

[60] On the one hand, the extraction can lead into an exhaust duct, in this way

To reduce odors or contamination of other food to a minimum. Depending on the specific configuration, this exhaust duct can open into further exhaust ducts, which leave a building. Likewise, it is conceivable to end the exhaust duct, for example, in a sub-housing, there to use the exhaust still as cooling air, but in particular depends on the temperature regime of the grille, for example, whether the temperatures in the sub-housing, in which the exhaust duct opens, are higher than in the grill gap, taking into account the airflow caused by the extraction and the inflow of cool outside air.

[61] The suction preferably leads the extracted air through one or even several filters or through another cleaning device. In this way, contamination of subsequent assemblies can be reduced to a minimum, which is particularly true when the extracted air is to be performed in a housing part or in the housing for cooling purposes or other purposes. But also a combination of the environment of Continuous grills or any subsequent exhaust ducts can be reduced in this way to a minimum.

[62] The grille may have means for changing the grill gap. The latter can be done, for example, that the diameter of the grill rolls are varied, but which is structurally relatively expensive. As a much simpler proves a change in position of the grill rollers to each other, which leads depending on the specific nature of the change in position to a corresponding change in the grill gap. Thus, for example, at least one of the grill rollers along a guideway be designed to be displaceable. It is particularly preferred if this guideway is circular and the circle center is located on an axis of a drive shaft of the corresponding grill role, so that the drive of the respective grill role does not have to be mitverlagert also accordingly.

[63] if necessary For example, the size of the grill gap, which may be measured or detected via the changing means or also via the monitoring means described above, for controlling the passage speed of the grill food or the rotational speed of at least one of the grill rolls and / or for controlling the temperature of at least one of the grill rolls or be used an associated heater, which leads in particular because of the multiple use of corresponding modules to a cost-effective implementation of the grille.

[64] Good frying results with different grilled food can be achieved by a method for roasting grilled on a grille with at least two, preferably three, at least one grill gap forming grill rolls, if this is characterized in that the speed of passage of the Grillguts by the grill gap in dependence is regulated by the type of grilled food, by a Walzenandruck, the size of the grill gap and / or by a temperature measurement. Both the Walzenandruck, as well as the size of the grill gap and the temperature measurement give structurally simple way individually and in particular significant information about the current state of the grilling, so on the passage speed, the action on the food to be grilled easily and precisely adapted to the respective Grillgut can. Depending on the concrete implementation, cumulatively or alternatively, a temperature control of the passage grill, so in particular any grill rolls, if they have a heating, be made.

[65] In this respect, good frying results with different grilled food can be achieved by a method for frying grilled food on a continuous grilling with at least two, preferably three, at least one grill gap forming grill rollers, if this is characterized in that the temperature of at least one of the grill rolls depending on the type of grilled food, a Walzenandruck, the size of the grill gap and / or a passage speed of the grill by the Grill gap is regulated.

[66] In this case, the temperature measurement can include in particular a locally measuring thermometer or a thermosensitive color change region, which can accordingly be detected by a color sensor, which is structurally simple to implement and accordingly permits precise temperature data.

[67] It is understood that the color change may vary depending on temperature

Show colors, or different areas that react color sensitive to different temperatures.

[68] In this case can on the temperature of the grill role, which ultimately directly with the

Surface of the food comes into contact, be ensured that a sufficient amount of energy is entered into the fried food, without damaging the surface of the food, in particular by burns, while on the other hand, the total amount of energy that enters the fried food and the cooking process defined inside, can be defined.

[69] Although measuring methods are conceivable, over which the kind of the grill good, which is given to the Durchlaufgrill in each case, can be determined. This can be done for example via optical sensors but also via chemical sensors. However, such measuring methods at present seem very time-consuming, so that it is advantageous to specify the type of food to be grilled via input means provided on the conveyor grille. With this input, then, for example, the temperature or the flow rate can be adjusted according to the food to be grilled, in this regard, other sizes, such as the Walzenandruck the grill rolls or the size of the grill gap with their significance in terms of the thickness of the grill or roast, considered here can be.

Accordingly, it is cumulative or alternatively to the other features of the present invention advantageous when a grille with at least two, preferably three, at least one grill gap forming grill rolls by a speed control of the grill by the grill gap or the rolling speed of at least one grill roll in Dependence on the type of food to be cooked, of a Walzenandruck, of the size of the grill gap (13) and / or a temperature measurement is characterized. Also, it is accordingly cumulative or alternatively to the other features of the present invention advantageous if a passage grill with at least two, preferably three, at least one grill gap forming grill rolls by a temperature control of at least one of the grill rolls depending on the type of grilled food, from a Walzenandruck, characterized by the size of the grill gap and / or by a speed of passage of the Grillguts through the grill gap.

[71] Before stopping the roasting process, at least one of the grill rolls can be without

Turn the heating and a mechanical cleaning agent, such as a cleaning sponge, a cleaning panel or a cleaning pad, be passed past the rotating grill roll. In this way, frying residues can be removed quickly and reliably, so that on the one hand hygienic requirements but also any flavor contamination can be reliably avoided on different grilled food.

[72] For example, the grill roll may be provided with a reversal of direction with respect to the direction of rotation used in continuous grilling to increase cleaning effects.

[73] Cleaning panels have the particular advantage that they possibly also constantly on the

Grill role can rest or can be structurally integrated into the grille, even if they are then brought only for cleaning purposes via a corresponding adjustment to the respective separation roller.

[74] The cleaning preferably takes place only when the cleaning temperature limit falls below a threshold, so that impairment of the cleaning agent can be avoided. It is advantageous if the grille indicates that the cleaning temperature limit falls below the threshold so that the operating personnel or a user can be reliably informed when the cleaning temperature limit has fallen below.

[75] It is understood that the features of the solutions described above or in the claims can optionally also be combined in order to implement the advantages in a cumulative manner.

Figure 20 is a schematic representation of a scheme for passage grills.

The conveyor grill 10 shown schematically in FIG. 1 has three grill rollers 20, which are arranged in a housing 11.

The grill rollers 20 form a grill gap 13, through which grill food, which is entered from above into the grill gap 13 in an input 16, can go through this then grilled at an exit 17 and to get to a Ausgaberost 12, from which it then the passage grill 10 can be removed.

[79] One of the grill rolls 20 is represented along a grill gap changing means 15

Guideway displaced to adjust in this way the grill gap 13 to grill food with different thicknesses. Alternative grill gap changing means 15 are shown by way of example in FIG. [80] The grill rollers 20 are driven by a motor 14 shown schematically.

The motor 14 drives, as exemplified in Figure 19, gears 18, which in turn drive the grill rollers 20. The axis of rotation of the large gear 18 of Figure 19 corresponds to the axis of rotation about which the grill gap changing means 15 displace the corresponding roller 20, so that the rotational forces can be transmitted simply and easily. In a selected embodiment, this roller 20 can be prestressed in the gap symbolizing the grill gap changing means 15 via a spring in the direction of the other grill rollers 20, so that the adjustment of the grill gap 13 takes place through the grill food itself. The deflection is then a direct measure of the thickness of the grill food or the grill gap thirteenth

[82] The motor 14 is provided with a torque detector 61 (shown schematically), which constitute monitoring means 60, by means of which the grill gap 13 can be monitored for the presence of grilled food in the grill gap 13. Likewise, an ultrasonic sensor 62 is provided on the housing 11, which monitors by means of ultrasound the grill gap 13 on any Grillgut as monitoring means 60. The monitoring means 60 moreover comprise pressure sensors 63 which measure any pressure exerted on two of the grill rollers 20 in the grill gap 13. Also, any measuring means for measuring the thickness of the grill gap 13, for example via the grill gap changing means 15, can serve as monitoring means 60. It is understood that deviating embodiments may possibly omit some or all of the monitoring means 60.

[83] As shown by way of example in FIG. 19, a housing may be provided on the housing 11

Grillgutaufgabe 19 are placed, which feeds grill or roast the grill gap 13 in the manner of a sliding guide when the latter of Grillgutaufgabe 19 is abandoned. In particular, can be stored in a sufficiently large-sized Grillgutaufgabe 19 a number of individual grill or Bratgutstücke, which are then fed successively to the grill gap 13 by gravity. In alternative embodiments, the Grillgutaufgabe 19 may also be firmly connected to the housing 11.

The housing 11 comprises three sub-housings 57, 58, 59, of which in one

Part housing 57, the grill rollers 20 are arranged, while in the second part of the housing 58, the motor 14 can be found. The third sub-housing 59 is spaced from the grill rollers 20 by the second sub-housing 58 and serves in particular the housing of electronics 66 (see FIG. 20), which is isolated in this way on the sub-housing 58 of the grill rolls 20 and by the grill introduced by these in the passage 10 temperatures.

The flow grill 10 also has an exhaust 70 (see Figures 1 and 9), which extends into the housing part 57 and serves to suck air from the grill gap 13 and from the housing part 57, in this way odors or any To reduce contamination to a minimum.

[86] As shown particularly in FIG. 9, the exhaust 70 comprises one of a

Fan motor 71 driven fan 72, which sucks air from the grill gap 13 and from the housing part 57 by a metallic filter 73 which is held by a filter holder 74. For this purpose, the fan 72 is located in a suction channel 76, which through the housing 11 through to an exhaust duct 75, which can be connected from the outside, leads. About the exhaust duct 75, the air can then be discharged to the outside, in order to reduce odor in this way.

[87] In a different embodiment, as far as the filter 73 can be sufficiently cleaned and the intake air is not too hot due to the amount of air, the suction channel 76 can open into the sub-housing 58 or the sub-housing 59, thereby providing air cooling this sub-housing 58, 59 to allow.

The suction 70 is dimensioned such that a sufficient flow of air through the inlet 16 and the outlet 17 into the housing 11, taking into account any leaks in the housing 11, such as slots between cover plates, micro-openings in the area and threads or rivets or the like , can be guaranteed.

[89] Depending on the specific design of the grille 10, the grill rollers 20 may be heated or unheated. Also with regard to the type of heating different configurations are conceivable.

Thus, as shown for example in FIG. 2, at least one of the grill rollers 20 may be provided with a heater 30 in the form of a heating coil spirally arranged inside the grill roller 20. Also, in the grill roller 20, a thermometer 40, which is formed in the embodiment shown in Figure 2 as a resistance thermometer 41, is arranged. In the embodiment shown in Figure 2, the thermometer 40 is located in the middle of the grill roller 20, wherein here - depending on the specific requirements - also a different location can be selected if a corresponding temperature detection is desired. It is understood, in particular, that possibly also a plurality of thermometers, in particular also different thermometers, which are suitably positioned, can be provided.

However, heating elements 32 can also be used as heater 30, as shown by way of example in FIG. In this embodiment, four heating rods 32 are arranged parallel to each other and parallel to the axial direction of the grill roll 20 in the grill roll 20. They are aligned in this embodiment equidistant from each other, in other embodiments, if necessary, a non-uniform distribution can be selected, although a corresponding non-uniform distribution of the temperature is desired.

[92] In the embodiment shown in Figure 3 is a thermometer 40 a

Thermocouple 42 is disposed inside the grill roller 20, which is located on a central plane but not in the center but in the vicinity of an inner wall 23 of the grill roll 20 to locally there to be able to measure the temperature as accurately as possible. It goes without saying that another thermometer 40 can also be chosen here in a different embodiment. In particular, it is also conceivable to arrange the thermometer 40 elsewhere or even to provide several thermometers 40.

[93] The heating of the embodiment according to FIG. 4 essentially corresponds to FIG

Heater 30 of the embodiment of Figure 3. As a thermometer 40, however, a color change region 44 is arranged on the inner wall 23 of the grill roll 20, which changes its color when a temperature limit is exceeded or fallen below. The color change or the color change can be detected via a color sensor 43, which is arranged inside the grill roll 20 and directed to the color change area. In the present embodiment, the color change or the color change is provided at a temperature above which can be grilled.

[94] In the case of the grill rollers 20 shown in FIGS. 5 to 7, a heating cartridge 33 is used as the heater 30. In the embodiment shown in Figure 5, the heating element 33 is relatively small and arranged eccentrically, so that the distance to the inner wall 23 of the grill roller 20 is less than half the inner radius of the grill roller 20.

The heating cartridge 33 of the heater 30 according to Figures 6 and 7, however, is designed much larger and leaves a continuous annular gap to the inner wall 23 of the grill roll 20, which is eight percent of Innenradiusses the grill roll 20. [96] In the embodiment according to FIG. 6, the thermometer 40, which in this exemplary embodiment is designed as a thermocouple 42, is located on the heating cartridge 33. Because of the very narrow annular gap to the inner wall 23 of the grill roller 20, it can be assumed that this thermoelement 42 the temperature on the inner wall 23 of the grill roller 20 can measure relatively accurately by isolating the thermocouple 42 as much as possible thermally inwards to the heating cartridge 33.

[97] In the embodiment of Figure 7, the thermocouple 42 is in the

Cartridge 33 poured so that the temperature of the heating element 33 measured very accurately and this can then be controlled well in their temperature with a corresponding electronics, such as the electronics 66, or temperature control 68.

In the embodiment of Figure 5, the thermocouple is cantilevered in the

Near the inner wall arranged.

[99] The thermometers 40 and the heaters 30 are each via electrical connections

51, 52 which protrude from the grill rollers 20, supplied with energy or connected to the electronics 66 and another control electronics.

In this case, in the exemplary embodiments illustrated in FIGS. 5 to 7, the electrical connections 51, 52 are each located at one end of the respective heater 30 or heating cartridge 33, so that they can also be easily connected to the electronics 66 at the corresponding housing side , It goes without saying that the embodiments illustrated in FIGS. 2 to 4 can also be designed in such a way by corresponding heating coils 31 or heating rods 32 laid in loops.

[101] The temperature of the heater 30 and / or the rotational speed of the grill rollers 20 can be controlled via the thermometer 40, which are all electrically configured and locally measured in these embodiments, depending on the specific control, including the electronics 66 with their speed control 67 and its temperature control 68 (see FIG. 20) is used. This regulation can be carried out much more reliably than with known integrating measuring thermometers, as represented by expansion rods, for example. It is understood that in such embodiments, however, such integrating thermometer 40 or other non-electrically effective thermometer can be used. [102] Depending on the concrete implementation, those shown in Figures 2 to 7

Embodiments can be combined or varied by changing the heaters 30 and the thermometers 40 and / or repositioning them.

Under certain circumstances, a variation of the grill gap over the grill gap changing means 15 shown by way of example in FIG. 1 is very complicated and undesirable, so that a grill roll 20 comprising two partial rolls 21, 22 may optionally be used, as shown by way of example in FIG. In this case, the two sub-rollers 21, 22 have different diameters and, moreover, are of cylindrical design, which accordingly leads, in interaction with the other grill rollers 20, to a varying grill gap 13.

[104] As shown in FIG. 10, cleaning panels 81 can be scraped against the

Grill rolls 20 abut, which is particularly advantageous in grill rolls 20 made of stainless steel. About the cleaning panels 81 then any grilled food residues that adhere to the grill rollers 20, scraped or removed. Depending on the specific design, these cleaning panels 81 can constantly scrape along the grill rollers 20 and thus constantly perform their cleaning work or be added as needed and fold away trained.

[105] Such cleaning panels 81 can also be used, for example, in grill rolls 20 provided with an enamel layer.

However, the constant friction load appears in grill rolls 20, which with a

Non-stick coating, such as are provided with Teflon ^® , too aggressive, so here, for example, a cleaning pad 82 may be used, as shown by way of example in Figure 11. This can then be promoted by the rotating grill rollers 20 along the grill gap 13 and provide its cleaning performance. In this case, it is possible for the material of the cleaning pad 82 to be matched to the surface of the respective grill rollers 20. Preferably, the cleaning is carried out only when a cleaning temperature limit is exceeded. This cleaning temperature limit can be measured, for example, by the thermometers 40, as already described above, and displayed to a user via the electronics 66 of the flow grille 10 and a corresponding display 68 (see FIG. 20).

[107] It is understood that for cleaning the direction of rotation of the grill rollers 20 may possibly be reversed, if this appears advantageous. [108] In the arrangements shown schematically in Figs. 6 and 7, it proves relatively difficult to correctly position the heating cartridge 33 with respect to the grill roller 20. For this purpose, the heating cartridge 33 bearing pins 39 or bearings 34 (exemplified figured), by means of which the heating element 33 is rotatably mounted on the grill roller 20 via an inner pivot bearing 28, as this is exemplified in Figures 12 and 15. This allows a very stable storage of the heater 30 with respect to the grill roll 20. Cumulatively or alternatively can be done via the bearing pin 39 or corresponding bearings 34 on the heating element 33 a stationary storage of the heating element 33 with respect to the housing 11, as exemplified in Figures 16 to 18 shown.

Depending on the specific embodiment, a rolling bearing or a sliding bearing can be used as a rotary bearing, wherein - as shown in particular in Figures 13 and 14 - plain bearings have proven to be particularly advantageous.

For example, a plastic ring can be used as an inner rotary bearing 28, as shown by way of example in FIG. Such a plastic ring can in particular also thermally insulating or as insulation 36, in particular with respect to the heating element 33, act. In order to increase the thermal insulation capability, it is also conceivable, for example, to provide the plastic ring with radial webs, so that any heat conduction through the material is reduced.

[111] In a different and schematically illustrated in Figure 14 embodiment, the surface of the grill roller 20 and the surface of the heating element 33 slide directly on each other, wherein for reducing the heat transfer as insulation 36, the region of the heating element 33, which is in contact with the grill roll 20 comes with radially inwardly directed recesses, so that only a very small contact surface remains.

[112] Depending on the specific embodiment, for example, the heating cartridge can be fixed in the housing 11 of the grille 10 (see Figures 16 to 18), so that on the inner pivot bearing 28 and the grill roller 20 can be stably stored and another camp for the Grill role 20 is not necessary.

[113] Preferably, however, the grill roller 20 is in each case via an outer pivot bearing 29 in the

Housing 11 stored so that, above all, the heating cartridge 33 is isolated as possible from the other modules of the conveyor grille 10. It then only needs to be stabilized in its direction of rotation, which is already the case, for example, by the not shown in Figure 12 electrical connections can occur, which can correspond in particular to the arrangements shown in Figures 6 and 7.

As can be seen immediately disassembly of the assembly of heating cartridge 33 and grill roller 20, as shown in Figure 12, relatively expensive, since roller pins of the grill roller 20 must be removed to remove the heating element 33 from the grill roll 20 or to lead into this.

Here, the arrangement of Figure 15, in which the grill roller 20 has a substantially cylindrical inner diameter, which is characterized in particular by the fact that the ends of the grill roller 20 are larger in diameter than the heating cartridge 33 so that they possibly light can be removed or used.

It is understood that on the inner pivot bearing 28, if necessary, other or further

Assemblies which are to be arranged within the grill roller 20, can be stored or held.

[117] The embodiment shown in FIG. 16 essentially corresponds to FIG

Embodiment of Figure 12, but here the bearing points 34 forming bearing pin 39 are mounted in a serving as insulation sleeve 36 (not numbered separately) on a headband 37, which serves as a support group 38 for attachment to the housing 11.

[118] In the embodiment shown in FIG

Embodiment of Figure 15 corresponding heater cartridge 33 for application, the bearing pin 39, however, each before head on the ends of the heating element 33 bearing points 34, via which the heating element 33 is clamped with serving as a support group 38 headband 37. The retaining clips 37 interact with the heating cartridge 33 via a point at the bearing points 34, so that a thermal resistance is formed here, which serves as insulation 36.

[119] Similar punctual heat transfers are shown in FIG

Embodiment formed by not numbered bolts, which are screwed into the there also used for use headband 37 and sit on bearings 34 of the heating element 33. In addition, insulating layers 35 in the form of plastic discs are provided in this embodiment between the headband 37 and the support group 38 and the housing 11 in order to reinforce the insulation 36. It is understood that in deviating embodiments, other types of insulating layers 35, such as films or paints or the like may be provided.

The heating cartridge 33 shown in FIG. 18 has no separately formed or molded-on parts

Bearing 39 on which pass in this embodiment, cylindrical in the heating cartridge 33. It is understood that with a suitable adaptation of the carrier group 33 and the holder for this purpose, other types of bearings 34 and bearing journals 39 may be used.

[121] The embodiments illustrated in FIGS. 16 to 18 can be used without

Further be combined with the embodiments of Figures 12 to 15, for example when the support groups 38 and / or insulators 36 of the embodiments shown in Figures 16 to 18 in the embodiments of Figures 12 to 15 are supplemented or if for example in the embodiments of FIGS 16 to 18 and an inner pivot bearing is used, which may be waived if necessary then on the outer pivot bearing 29.

[122] In particular, the exemplary embodiments illustrated in FIGS. 12 to 18 can be provided with electrical connections, as are disclosed by way of example in FIGS. 5 to 7, wherein the electrical connections may pass through the respective retaining clips 37 or carrier groups 38 These can be passed over.

The electronics 66 comprises on the one hand a speed control 67 for at least one of the driven grill rolls 20, wherein, if all the grill rolls 20 are driven as in the embodiment according to FIG. 19, then all the grill rolls 20 are also controlled accordingly since the electronics 66 drive the motor 14 controls. On the other hand, the electronics 66 include a temperature control 68 for the heater 30 by being controlled according to the desired temperature, the measurement results of the thermometer 40 are substantially relevant here.

[124] Furthermore, the monitoring means 60 and input means 69 serve as

Inputs into the electronics 66, wherein the input means 69, the indication of the type of grilled food, for example, whether fish, chicken, beef or pork, allow.

[125] In the embodiment shown in FIG. 20, a rotary switch serves as

Input means 69, where certainly also a button bar or a keyboard, a touch screen or the like can be used. [126] The electronics also controls a display 65, which on the one hand, the selected

Grillgut and on the other hand indicates the achievement of a cleaning temperature. Alternatively or cumulatively thereto, the achievement of the preset temperature for grilling, the current temperature or other information, such as the choices of grilled food or, in relation to complex input options and the current input can be displayed.
