Description

The Invention relates to a toasting device, with the addition of the actual toast process of certain baked goods also ready baked or baked almost baked goods or can be refreshed or pre-baked dough baked ready can.

For the implementation of this Baking processes are known for many years different devices. This can Stove ovens, Mini ovens, toast equipment and microwave ovens.

These device groups have the disadvantage that in none of these devices old well-known baked products can be optimally processed. At the The most effective is still the Toastgerät, with the restriction that the known Solutions for this equipment the problem of the baking process for wheat / rye pastries only with limited Execute success can.

The Stove or mini oven generally have the disadvantage that they have a relatively high power consumption to have.

The oven ovens have the further disadvantage that they for the Processing of individual pieces of the Backgutes, due to the large Volume of the baking chamber, an even worse ratio of baked goods volume to use energy.

Further are these ovens for pure Toast tasks also energetically unprofitable. With microwave ovens can Although the thawing of frozen ready baking or baking done by dough fast be a finish baking and creating an appealing golden yellow tanned However, crust of the baked good is solely with the use of microwaves not possible.

With the EP 0 966 180 A2 a baking device is specified in which a system is integrated to reduce or to achieve a constant distance of the heat source to the dough.

The Heating elements are rotatably mounted or folded down. The dough is placed on the receptacle and with the commissioning of the equipment The heating elements move in relation to a certain position the dough. During the Turning the recording is the baked goods always and directly under the Heat input.

From the GB 891 871 For example, a toasting device is known in which the toasting device is combined with a cutting device for cutting slices from a loaf of bread.

Over or under the entire area of the rotatable device for the holder the sliced toast is a spiral heating element or are more spiral-shaped Heating elements arranged, whereby the Toastgut constantly under the action of thermal radiation lies.

From the DE 10 2004 044 247 A1 Furthermore, a baking method and a baking apparatus for carrying out the method for the refreshment of fresh or almost finished baked baked good or for the ready baking of baked baked goods is known, in which the following process steps are performed:
The ready-to-bake or refreshed baked goods are stored without significant moisture loss after Erstbackprozess; before starting the baking, the baking chamber is preheated or cooled to a standby temperature; the baked goods are placed in the oven at standby temperature. The respective baked good is shock-like, heated up to a maximum surface temperature for the particular bakery product.

at Reaching this surface temperature limit the heating process is interrupted and if necessary, the baked good also cooled on its surface, wherein depending on the size of the baked goods the two previous steps heating and cooling until reaching the desired Core temperature can be repeated.

The specified baking device is characterized in that a closed oven for at least one piece the size of the respective product group arranged adjusted is that on all sides of the oven known per se heating elements outside the baking chamber are arranged and that cooling possibilities for the oven are provided.

Furthermore, the specified baking device is equipped with known time and / or temperature-dependent control devices. Furthermore, in the DE 10 2004 044 247 A1 indicated that for the implementation of the baking process with a standby temperature of preferably about 300 ° C is used.

The shock-like baking process, preferably at temperatures up to 400 ° C and preferably in a time interval of 30 to 180 seconds depending on the size and type of baked good, is carried out so that a surface temperature of 120 ° C to 190 ° C is set as the surface temperature limit and that interruptions of the heating process are made, preferably bakery shape dependent, especially in baked goods with a preferred direction of expansion, that the heating elements in time step by step be shut off with the achievement of the surface temperature limit at the respective bakery region preferably affected by the heating power of the controller.

Definitely can with this baking process or with the appropriate baking device the dough in appropriate quality to be baked. A disadvantage of the aforementioned baking processes it, however, that before the actual baking of the baking chamber of the appliance to a preheat temperature, such as stated about 300 ° C must be brought and that the outside the baking chamber heating elements provided the entire oven to heat up, which requires a considerable amount of energy.

in addition comes that the Heating elements in time with the achievement of the surface temperature limit be switched off again by the controller so that one more or less change between heating and cooling record is, and these are frequent Change inevitably negatively affect the service life of the heating elements.

Of the The present invention is based on the object of providing a toasting device, with which dough and / or other food can be toasted but also pre-baked baked goods can be finished baked.

According to the invention this Task, with a Toastgerät solved according to the preamble of claim 1, characterized in that the heating elements arranged in the form of halogen lamps with respect to the turntable (s) are that the heating elements over the turning surface produced by the turntable (s) constitutes a heat input sector, go through the at least parts of the baked good in its rotary motion.

one the main advantages of this solution according to the invention is that by the movement of the material to be treated by means of the turntable for a very even heat absorption guaranteed by the dough and on the other hand, the effect is achieved that with the exit of the baked goods from the heat input sector, d. H. on the side facing away from the emitters, the registered amount of heat from the illuminated surface can spread to the core of the baked goods.

Farther it is advantageous that the toast device no preheating time needed there with the use of halogen lamps as a heat source immediately the entire heat energy can be provided, resulting in a significant saving leads to electrical energy.

In Advantageously, the halogen lamps are annular with a distance to the Turntable outside at the heat registration sector the circulation arranged.

advantageous Further developments and refinements of the invention are evident from the remaining subclaims and from the principle described below with reference to the drawings embodiment seen.

1 a perspective view of the Toastgerätes;

2 a schematic exploded view of the Toastgerätes.

In the 1 becomes a toast 1 shown in a perspective view.

Here's the toast 1 with two turntables 4 executed.

The housing 3 was designed in a hexagonal cross-sectional shape, with an upwardly facing part of a hinged lid 3c as access to the interior of the oven 2 is trained.

About the turntables 4 are tubular halogen lamps 5 arranged. The heat emitted in the switched-on state does not completely cover the turntables 4 but only one sector 6 ,

The size of this heat input sector 6 Depending on the device type or type of about one eighth to about three quarters of the surface of the turntable 4 be.

The straight-shaped tubular halogen lamps 5 are here arranged so that the radiant heat emanating from them can hit the dough at an angle of <180 ° and at a distance of about 30 to 60 millimeters.

The shape of the tubular halogen lamps 4 but can also by a curved execution the heat registration sector 6 be largely adapted.

Also possible is an embodiment in which tube-shaped and radiator-shaped halogen lamps 5 combined can be used.

When switching on the halogen lamps 5 a part of the baked goods lies directly under the heat radiation. With the forward turn of the turntable 4 Now this part goes out of the heat registration sector 6 out and gets into a cooler area of the oven 2 , So that the absorbed amount of heat from the surface of the baked good to the core can spread out.

At the same time, the subsequent section of the baked goods will now be transferred to the heat registration sector 6 is rotated and is also heated there, so that alternately a warming phase alternates with a cooling phase. The treatment process is only subject to a temporal control; The duration of treatment is about 60 to 120 seconds, depending on the type of baked good and the degree of browning to be achieved. After switching off the halogen lamps 5 is a relatively rapid drop in temperature in the oven 2 to record, whereby a burning of the baked good can be almost excluded.

On Reason for this very short treatment times is next to a low Energy consumption (about 15 W / piece) Even a very small loss of water in the dough to record.

In the here given embodiment with two turntables 4 A simultaneous processing of toast and wheat / rye pastry can be done in one baking process.

It is also possible that in addition a microwave generator individually or in combination with the halogen lamps 5 is switchable as a heat source.

With this embodiment can be frozen Baked goods can also be baked in about 120 seconds.
