"Machine for fried potatoes"

The present invention relates to a roast potato machine, that is to say a fully automatic one Device for frying and packing potatoes, after inserting a certain number of coins, tokens or the like. Without any human intervention, a portion of fried potatoes roasted, packaged, whether or not you choose sprinkled with salt and finally made available to the buyer.

Various solutions have already been proposed for such fried potato dispensers; these ways However, disadvantages of such a nature that a general use, especially in cases where servings of fried potatoes taken at irregular times is out of the question.

Such devices come in two main types.

In devices of the first type, an endless chain is used, with baskets attached to it at regular intervals are rotatably suspended; these baskets are first placed under a storage container with ready-cut potatoes,

and then through a vessel with hot oil or fat passed through where the potatoes are fried; eventually the baskets become one by one tipped over, each time the contents of the basket are placed in a package.

Such a device works relatively well in cases where portions of fried potatoes are constantly being served be removed, but it is unusable if only now and then, at irregular times, individual por- " functions should be removed.

In devices of the second type, a portion of fried potatoes is made from one each time a coin is inserted Removed storage container, which then falls into a basket, after which this basket with its contents in a kettle with hot oil or fat is immersed. After the potatoes have been fried, the basket is removed from the cauldron taken out and tipped over a funnel so that the Fried potatoes in a package, e.g. a bowl, got into it.

The present invention relates in particular to a fried potato dispenser of this second type, which characterized by high profitability and among all Circumstances can be used without any difficulty. For this purpose, the device according to the invention the following features:

According to a first feature of the invention, the storage drum used in the fried potato dispenser is included With regard to proper ventilation and / or cooling

209819/0029

The pot is a stock made from a perforated sheet metal or something similar Material produced, this storage drum preferably continuously with the outside air and / or with is connected to a cooling system ..

Experience has shown that such ventilation or such cooling, depending on the the temperature conditions in the vicinity of the machine, is necessary so that the fried potatoes become crispy.

According to another feature of the invention There is at least one device on this storage drum Driver cups, preferably two or more, are provided which are so effective that adding enough small quantities of potatoes be taken by a basket each, the desired total amount per portion measured with the greatest accuracy can be.

Yet another feature of the invention is to be seen in the fact that, in order to prevent heat losses from the space where the the mentioned boiler with hot fat or oil is located, to the space in which the mentioned storage drum with potatoes is housed, are kept as small as possible, between These two spaces an insulating partition is arranged, which on the one hand a perfect effect of the mentioned Ventilation and / or cooling ensured and on the other hand any heat losses from the roasting chamber to a minimum belittles.

Yet another feature of the invention can be seen in that the dimension in portions by weight, and does not take place according to volume, as has always been the case up to now

209819/0029

-it-

since each portion is also made by combining several is obtained in small quantities, an arrangement results which allows each portion to be measured very precisely. It is namely, it is very important that all portions are equal to each other, so that each one has a fixed roasting time equal quantities of potatoes for roasting can be dipped into the oil or fat so that it is always well-roasted Final product results.

Yet another feature of the invention is therein

"To see that a roasting basket is used of a special design is, as a result of which the loss of frying fat or oil that occurs when the frying basket is tipped over is kept as small as possible will; this not only results in the advantage of economical fat or oil consumption, it also becomes that The purity of the machine is promoted.

Yet another feature of the inventive fried potato dispenser can be seen in the fact that it contains a Salt distributor is provided, which by means of a selector switch or operating button arranged on the outside of the transmitter can be switched on or off depending on the wishes of the buyer; In addition, this arrangement has the advantage of that unauthorized operation of the salt dispenser is impossible. In the case of the previously known fried potato donors, there is one Such actuation by unauthorized persons is probably possible, since here the salt shaker is arranged by means of a on the door Push button can be operated independently of the effect of the encoder.

The inventive device that mentioned

209819/0029

and also has other features, consists mainly of a housing, which is divided into at least two separate ones Chambers is divided into a ventilated, resp. refrigerated pantry and a frying chamber; one in the mentioned ventilated or cooled storage chamber arranged storage drum with perforated walls; Arrangements that allow a portion or partial quantities to create a portion of moving fried potatoes from the storage drum into a weighing device; Arrangements for conveying the measured portion of fried potatoes from the aforementioned ventilated or cooled chamber into the mentioned roasting chamber, especially in the roasting basket; Arrangements for separating one peel per portion of fried potatoes a supply stack; Arrangements for pouring the fried potatoes into the aforementioned bowl and arrangements for optional application of a measured amount of salt to the fried potatoes.

In order for the features of the present invention to emerge more clearly, the following is given as an example, without any restriction of the breadth of the inventive idea, a preferred embodiment of the inventive concept Device will be explained in more detail with reference to the accompanying drawings.

BATH ORIGINAL

also arranged with a corresponding opening 85. Outside of the bucket 80, the slide 82 has a transverse extension 86; a spring 87 is permanent endeavors to keep the slide in the position shown in Figure 9.

The above-mentioned crank 65 can now come into contact with the mentioned transverse part 86 and counter to it influence the spring 87 so that the slide 82 is displaced inwards until the openings 81-8 3 and 85 in relation "are aligned with one another. The shaft 79 preferably continues to outside the encoder housing and is its protruding end is provided with a control button, with the help of which the bucket 80 can be moved into the position shown in Figure 9 can rotate the position shown by solid lines. This bucket forms the so-called salt distributor. With the help of the control button mentioned, it is possible to sprinkle salt on the portion of fried potatoes in the shell 67 either to enable or to prevent.

Under the lower bottom 84 of the bucket 80 is a Tube 88 is provided, which bends laterally further down and through an opening 89 into the interior of the arrangement 6 joins.

The operation and use of the arrangement described above are quite simple; you can do the following to be discribed:

Before the machine is put into operation, a certain amount is cut, if necessary also

209819/0029

Put pre-fried potatoes into the storage drum 4 after removing the lid 5; these potatoes are now continuously ventilated or cooled, since on the one hand the drum is made of perforated sheet metal and on the other hand the air through the openings 14 and 15 can circulate. The mentioned insulating plate 25 protects the chamber in which the drum is located against penetration the heat from the chamber 3. If the machine is then connected to the power supply, the drum 4 driven by the motor 8.

As the drum rotates, the potato pieces become each carried up in the side baskets 24? every time such a basket is over the collecting container 29 is located, the corresponding flap 19, in that the projection 22 comes into contact with the stop 2 3, opened so that the one located in the cup 24 The amount of potatoes falls into the container 29. The drum 4 continues to rotate until the weight of the in container 2 9 accumulated potato reaches a certain value. At this moment, the lever 36 is through the projection 35 depressed, whereby the contact 39 is actuated.

The actuation of this contact has the consequence that the switch 13 over one of the contacts 11-12 the motor switches off, after which the drum is in the position shown in the figure.

Two contacts 11-12 are provided on the disc 10, when the drum 4 has two lateral driver cages. If several cups are used, it also carries

209819/0 029

BAO ORIGINAL

-2Λ-

the disk 10 several contacts, namely as many contacts as cups are provided so that these cups are always in the desired position when the drum is stopped are located. The machine is now on hold.

If a buyer wants to buy a portion of fried potatoes, he only needs one or more coins or The like. For example by means of the slot 90 to introduce into the apparatus, after which a known per se, schematically

The coin mechanism indicated at 91 switches on the motor 51 which drives the cam disks 50 and 62.

As a result, the flap 27 is released by the rotation of the cam disk 50, so that these around their Axis 28 folds down, the potato pieces falling from container 29 into basket 53.

At the same time it causes the cam disc to rotate 62 that the roasting basket 53 is lifted up from the fat or oil during the opening of the flap, so that fat or Oil splashes are avoided. At the same time, the assembly 66 is appropriately actuated so that one of the Trays from the stack is attached to the grate 72.

After the portion of fried potatoes has been poured into the basket 5, it is returned to the liquid lowered while the flap 27 is placed horizontally again, after which e.g. by means of a not shown Switch the drive motor of the supply drum is put back into operation; the drum is in Rotation shifted until the switch 39 is operated again.

209819/0029

The roasting basket 53 remains for a certain time Duration, which is measured with the help of an adjustable time mechanism, in the oil or fat bath, after which the motor 51 is switched on again.

This now has the effect that the roasting basket is raised and tilted about the pivot axis 54, so that the Fried potatoes get through the funnel 76 and the opening 75 into the bowl 67.

During the tipping over, the crank 65 of the roasting basket 53 hits the slide 82 of the salt distributor and pushes this into the position shown in Figure 10, whereby a certain amount of salt through the each other subsequent openings 81-83-85 falls into the tube 88 and in this way on the fried potatoes in the shell 67 is poured up. Of course, this process only takes place when the salt spreader is in the fully extended position as shown in Figure 9.

This completes the entire process.

The invention is in no way limited to that described as an example and in the accompanying drawings illustrated embodiment, but it can be such Fried potato donors can also be realized in many other designs and dimensions, without the framework of the Invention to exceed.
