Description

  The present invention particularly relates to a Baumkuchen baking apparatus that uses thermal power from a gas burner.

  Baumkuchen, a baked confectionery born in Saxony-Anhalt, Germany, is a cake with a donut-shaped hole in the center and a concentric pattern like tree rings on the cross section. Baumkuchen cannot be made with ordinary ovens because of its special manufacturing method, and there are many ovens dedicated to Baumkuchen.

  The dedicated oven has a core for winding the dough and a driving device for automatically rotating the core, and a plurality of gas burners for baking the dough are installed in the lower part. The core itself can be moved between a firing position in the vicinity of the gas burner and a front take-out position via a pair of left and right tilt arms, and the Baumkuchen product after the baking of the dough wrapped around the core is completed. At the time of taking out and winding a new fabric around the core, the tilt arm is pulled forward to pull out the core. Thus, unlike a general oven that uses a radiant heat from a wall surface, the dedicated oven is an open type that bakes the dough with an open flame.

The authentic German Baumkuchen dough is made with butter, eggs, sugar, vanilla, marzipan, rum, and water. When a small amount of dough is baked on the surface of the rod that becomes the core and baked with a gas burner, a thin layer with a thickness of 1-2 mm with a burned surface is formed. Further, the baking process is repeated while applying the dough on the burned layer to produce about 10 to 20 thin layers. After baking, the core is removed and cut into rings, and the burnt and the white area inside when struck with a gas burner appear in layers, creating Baumkuchen that looks like a tree ring.
None

  However, conventionally, in order to take out the Baumkuchen product after the baking of the dough wound around the core and to wind the new dough around the core, the tilt arm is pulled forward to pull out the core. However, the gas burner's crater is always in an ignited state in which gas is blown out, which not only wastes gas and makes it extremely uneconomical, but also by spreading unnecessary hot air around it, It has the problem of causing considerable pain to Baumkuchen calciners in the summer. For example, the present inventor has been engaged in Baumkuchen baking work such as performing arm operations almost hundreds of times every day for 30 years, and alleviating pain caused by hot air at the work site is an urgent issue.

  Therefore, the present invention has been devised in view of the conventional circumstances as described above, and when the dough is fired by moving the core to the firing position near the gas burner via the tilting arm, the gas burner is used. When the gas is supplied and when the Baumkuchen product is taken out after baking of the dough and the new dough is wrapped around the core, when the tilt arm is pulled forward and the core is pulled out, the gas is not supplied to the gas burner. An object of the present invention is to provide a Baumkuchen baking apparatus capable of reducing unnecessary gas consumption and preventing unnecessary hot air from being scattered in the vicinity by being stopped.

In order to solve the above-described problems, in the present invention, a gas burner provided with an open / close valve for baking the dough, and a firing position in the vicinity of the gas burner on the back and a take-out position on the front via a tilting arm A Baumkuchen baking apparatus comprising a core for winding the fabric that can move between the two and a drive device for automatically rotating the core, and adjusting the valve between the tilt arm and the open / close valve a mechanism, the valve adjusting mechanism, in conjunction with the movement of said opening and closing valve in association with the movement of the drawing direction of the core due to the tilting arm closing available-and the firing position of the gas burner near the core by the tilting arm and so as to be capable opening the closing valve, an electromagnetic valve which is interposed in the middle of the gas pipe, the conjunction with the tilting movement of energization actuating the solenoid valve forward or backward tilting arm In Rukoto, characterized in that it is constituted by a solenoid valve on-off valve formed by so as to shut off or opening the gas flow path of the gas pipe.

  According to the present invention, the gas is supplied to the gas burner when the dough is baked by moving the core to the baking position near the rear gas burner via the tilting arm, and the Baumkuchen product is taken out after the baking of the dough is completed. When a new fabric is wound around the core, when the core is pulled out by pulling the tilt arm toward the front, the gas supply to the gas burner is stopped, thereby reducing unnecessary gas consumption. it can. Specifically, the gas use cost can be reduced from the conventional one-third to one-fourth.

  Further, according to the present invention, unnecessary hot air is scattered around the periphery, so that it is possible to minimize the pain to the Baumkuchen baking worker especially in summer.

Further, as the valving mechanism to close or open the opening and closing valve of the gas burner, since the thus configured electric solenoid valve type, the opening and closing switch adjustment of the opening and closing valve of the gas burner via the operation of the tilting arm It can be easily realized by a simple configuration.

The best mode for carrying out the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the Baumkuchen baking apparatus according to the present invention can be transported by casters K provided at the lower four corners, and includes a baking chamber 1 having an open front side on the upper side. A plurality of pipe-shaped gas burners 3 branched from the lower main pipe 2 and arranged in parallel in a vertical lattice shape are provided on the back side in the baking chamber 1, and the main pipe 2 is a gas pipe 5 provided with an original valve 4. For example, it is connected to an LP gas cylinder or other gas supply source (not shown).

  Specifically, the gas burner 3 generates a heat quantity of about 21000 Kcal or more from the crater by an automatic ignition mechanism (not shown), and the convection heat can heat the surface of the dough Q to the target brown with high heat efficiency. Moreover, the heating power and air in the gas burner 3 can be adjusted as appropriate.

  Further, a tilting arm 7 that can be rotated forward and backward by a support shaft 6 provided on both sides of the baking chamber 1 is disposed, and a dough Q is wound around the upper ends of the tilting arm 7. Both ends of a circular core 8 for rotation are pivotally mounted via a bearing 9 such as a radial bearing or a thrust bearing, and the core 8 is attached by a driving device (not shown) provided inside the firing chamber 1. It is designed to rotate automatically. The tilt arm 7 is configured such that the core 8 itself can move between a firing position in the vicinity of the gas burner 3 at the rear and a front take-out position via an operation spring 7a provided at one end. . In addition, 10 in a figure is a mounting base for taking out a product from the core 8. FIG.

The gas pipe 5 between the main pipe 2 and the main valve 4 is provided with an opening / closing valve 11 for switching between supply and stop of gas to the main pipe 2. , Luba Lube adjusting mechanism P to be described later is attached. By this valve adjusting mechanism P, the opening / closing valve 11 can be closed in conjunction with the movement of the lead 8 in the pulling direction by the tilting arm 7 and the tilting arm 7 moves the lead 8 to the firing position near the gas burner 3. The on-off valve 11 can be opened in conjunction with the above.

In FIG. 2, there is shown valves adjusting mechanism P, interposed a solenoid valve 51 in the middle of the gas tube 5, the solenoid valve 51 in conjunction with the tilting movement of the forward or backward tilting arm 7 The solenoid valve type on-off valve 11 is configured to shut off or open the gas flow path of the gas pipe 5 by energizing operation. At this time, the electric wire 52 is connected to the other end side of the tilt arm 7 from one pole of the electromagnet of the electromagnetic valve 51 in a state having a margin length, and the power supply 53 is connected to the other pole of the electromagnetic valve 51. The contact terminal 54 is arranged on the rear side via the.

  The electromagnetic valve 51 moves the valve body by utilizing the force of an electromagnet (solenoid) that is actuated by an electric signal, and the structure of the electromagnetic valve 51 includes an electromagnet part and a valve part. Yes. As this electromagnetic valve, there are a pilot type in which a pilot valve is operated by a small electromagnet and the valve element is moved by the force, and a direct action type in which the valve element is directly moved by an electromagnet force. The electromagnet is made up of a solenoid coil and an iron core. When the coil is energized, the movable iron core (plunger) is attracted to open and close the valve.

  That is, when the tilting arm 7 is tilted forward, the electric wire 52 connected to the tilting arm 7 and the electromagnetic valve 51 and the contact terminal 54 are brought into contact with each other, and the coil from the power source 53 is energized.
