Description

Loading and emptying rack for multi-deck oven

The invention relates to a device for baking of foodstuffs, and in particular a device for loading and unloading open-deck ovens.

The invention can be based on conventional methods based bread making can be performed by bakers by making the required sequential actuations can be reduced by hand and the work done by the baker can be increased.

It is a particular object of the invention to reduce the amount of work required when transporting the dough lumps from the fermentation area. chamber to the oven as well as when removing the bread from the oven after baking and feeding to decrease to the point of sale.

In particular, the invention relates to a unit that consists of at least one furnace and one associated mobile Frame consists, wherein the furnace and the mobile frame has several floors, so that each floor of the mobile Rack can be placed in one day of the oven, all the more so by a single operation the lumps of dough on all Set down the floors of the oven at the same time.

It is in particular through the US-PS 3,752,640 and the German Offenlegungsschrift 2 059 004 a device known that consists of an oven and an associated mobile frame

909835/0772

consists, with each floor of the mobile frame in
penetrate a floor of the oven for loading the oven with lumps of dough in a single operation and the emptying of the oven also in a single operation
can be carried out.

According to this known method, the mobile frame places a lump of dough on each floor of the oven
Baking tray, which is pulled out after the baking process is finished, This has two disadvantages:

1. The lumps of dough are placed in a proofing cabinet before baking (for the dough to rise) and must
be brought onto the support surfaces provided with the metal sheets. Therefore (when using the known
Method) the dough lumps are manipulated to get from
the trays used to raise the dough
to remove and place on the trays or baking surfaces that are inserted in each oven level.

2. The lump of dough is placed on a baking sheet according to the method mentioned in US Pat. No. 3,752,640 and OS No. 2,059,004, which is then pushed into the oven. Thus avoids
there is direct contact between the lump of dough and the sole of the oven, which is why it is used to achieve a conventional method
For bread that is baked and used by the consumer, it is necessary to place the lump of dough directly on the oven sole.

The invention aims to provide a device for the conventional To create a bakery in which any manual operation between the proofer and the oven is turned off, but in a single operation

909835/0772 ^T

the fast and simultaneous loading of all oven levels is guaranteed and the dough lumps are placed directly on the bottom of each oven level without the interposition of a baking sheet. 'ψ

To this end, the invention provides one to be used for baking food products such as bread Device consisting of a multi-level deck oven and at least one mobile frame with several levels arranged bearing surfaces created that cooperate with the furnace that each bearing surface directly can penetrate into the furnace via a corresponding sole, and the device is characterized in that each support surface has automatic loading means, which consist of an endless sheet metal band that on two End rolls is guided, and that each tier of the furnace means for locking the lying on the corresponding support surface Belt for starting the run of the belt and for placing the product carried by the belt on the Has furnace sole during the retraction of the mobile frame.

Thus, the mobile frame can also serve to temporarily store the dough lumps during fermentation and them then immediately put down on the oven soles.

Further advantages and features of the invention can be found in the next description of one in FIG Preferred embodiment illustrated in the drawings. Here show:

FIG. 10 3 shows a support surface in a retracting division m-.zh at the rear by releasing the loading cone, the process of settling the dough lumps on the oven sole being evident here;

Figures 11, 12, 13 and 14 show the different ones below Sequence phases of the process according to the invention and the

Figures 15 and 16 show a detail of the locking and unlocking device of the band assigned to each support surface.

From the entirety of the figures it can be seen that the device according to the invention consists of a box designed as a box Furnace 1 is provided, which is provided with heat-insulating walls and whose interior is divided into several floors which each correspond to a single sole 2, 2 ', 3, 3'.

Preferably each sole consists of one made of refractory Material-made plate, which represents the top wall supporting the dough lumps during loading, each sole has in its thickness below the plate made of refractory material an electrical resistance of suitable Starch, which takes over the heating of the upper plate for baking the bread or baked product such as lumps of dough .

The front of the box is open to allow access to the soles arranged in tiers. This front side can be closed by the ¹ I ¹ Ur 4-, which is made of several for the purpose of isolation

909835/0772 " ⁹ "

Layers existing vertical window 5 is provided, through which the interior of the oven during the baking process can be monitored.

The 2! Ür points on its outer circumference and on the Box (in the closed position) facing side a seal 6 made of elastomer resin on ', which is pressed against the edge 7, which leads around the furnace interior, so that a sealed Completion in the closed position is guaranteed.

The loading device consists of a mobile frame which has a lower frame 9, which is essentially Is square and is carried by rollers 10, 10 'and 11, 11'. On one side of the frame are two vertical uprights 12 and 12 'attached through the Cross pieces 13 and 14 are connected to one another.

From the two vertical uprights go horizontally extending arms 15, 15 ¹ 16, 16 ¹ , 17, · 17 ', which over

the frame are cantilevered (Fig. 6). You have an angle iron with an L-shaped cross-section, its foot is turned towards the interior. Both angle irons (for example the angle irons 18 and 18 * of FIG. 6) thus have two arms carrying a support surface 19 (which form the guide rail).

The support surface is formed from an endless belt 20, which is carried by two end rollers 21, 21 ', which on the interconnected longitudinal beams 22, 22 'are attached and form the frame of the transfer layer. Thus, the support surface 19 can be inserted between the two horizontally extending arms 18, 18 ', wherein

- 10 909835/0772

the supports 22, 22 'themselves, on the horizontal edges 23 insert the angle iron, while the vertical edge 24 of the angle iron (Fig. 6) prevents lateral displacement. A transverse stop 25 at the end of each V / angle iron achieves the support surface is held in position.

The band 20 includes a cross bar 29 which protrudes slightly from each side. This pole is on the same level the seam through which the connection of two tape ends comes about to form the endless tape. The hem is . Further formed into a can 30, which sits riding on the hem. This makes a manual gripping device created for the operation of the belt.

The actuating device for the automatic loading is particularly shown in FIG. 8 and the subsequent figures shown.

Each individual sole 3 belonging to the oven is provided on the side and in the vicinity of the front edge 3 ^{1 of} the sole with a stop 3% 31 ', which is formed from a vertical sheet, which has an incline 32 and an incline 32 on its front side towards the interior of the oven has subsequent vertical end edge 33.

As can be seen from FIGS. 8 and 9, the transverse rod 29, which belongs to the supporting surface carrying the dough lumps 34-, 3A- ", 35, 35 ', is attached to the side arms 18, 18 * and penetrates until the The bars 29 of each surface meet the side stops 3I, 31 · and rise

- 11 -909835/0772

on the front ascending side 32 of the stops, until they fall down at the connecting edge 33 (FIG. 9).

The loading frame can then be withdrawn to the rear. During this movement, the belt is blocked at the level of each layer by the rod 29 at the stop ~ y \ , so that a backward movement of the frame causes the belt 20 to be unwound and the lumps of dough are deposited on the oven sole. With the device of the invention, a considerable rationalization of the work of the user can be achieved.

The lumps of dough lie on the individual support surfaces 19 and are then pushed onto the floors on the arms of the loading rack.

In this way, the dough lumps with the entire loading frame can be introduced into a proving cabinet in which programmed fermentation takes place in order to bring the dough to the right condition for baking at the allotted time, so that the baker or assistant can then pull the whole frame out of the cupboard, whereupon he can Without any intervention of one or the other device, the whole rack is placed directly in the multi-deck furnace introduces where a loading device described above, when the rack is withdrawn, the lumps of dough settles on the multi-level soles.

The loading frame of Figure 6 ¹ is identical to that of Figure 6, which is why the same reference numerals are used here:

The uprights 12 and 12 carry the from the angle iron 18, 18 'formed horizontal arms; between the two

- 12 909835/0772

However, iron bars are here (for example, by welding of the leg 23 of the L-shaped angle iron 18 under the inner surface) horizontal sheet metal plates are used. The plate 36 is therefore horizontally between. the two arms 18, 18 'that carry them; on each floor an identical plate 36 ', 37 »37' is provided.

Thus, a unique frame is used that can be used for loading and unloading at the same time.

Figures 15 and 16 show a structural detail, whereby it is possible to get the rods 29 free by completing the retraction of the frame.

If the lumps of dough are on the sole, the frame must leave the furnace completely, and it must therefore be prevented that the rods associated with each support surface 29 are held at the stops 31. For this Basically, the rear end of the longitudinal members 22 of each support surface has an upwardly pointing projection, the one Kind of cam forms against which the rod 29 is pressed, the slope 3 <? of the cam lifts the rod (see 16) until it is higher than the upper edge of the stop 31 and consequently releases the entire unit.
