Description

Cleaning device for dough treatment surfaces of Y / foul baking machines

Field of application of the invention

The invention relates to a cleaning device for the dough treatment surfaces of wafer baking machines for producing edible waffles from liquid wafer dough.

Characteristic of the known state of the art

Waffle baking machines, also called wafer ovens or Waffelbackautomaten, used in the confectionery industry for the production of wafer sheets, flat waffles, lower hollow waffles, cast hollow wafers, rolled hollow wafers u. like. More. These waffle products are a part of the machine-made fennel products known from the food and beverage industry, which are filled or unfilled on the market and commonly known as stimulants. These waffle industry products include rolled wafer packets, waffle cups, wafer plates, flat waffle slices, low hollow waffles, hollow sticks, ice cream cones, filled waffles, ice cream waffles, small filled waffle stalls, and the like. like. More.

These waffle products are waffle-dough baked products of crisp, brittle, soft and slightly fragile consistency, which are baked as dry as possible and have a very low moisture content of one to four percent. The waffle dough used for this purpose can have a relatively high sugar content of up to 30 % or more for the production of sweet waffle products. Such wafer doughs produce waffle products that are formable in the baking state. This property is used in the production of hollow sticks, sugar icings, Zuckerwaffelröllchen u. exploited, with each one first sinzelne

Baked wafer wafers or V / finnel patties or an endless waffle band and molded into the final shape in the soft or malleable state and allowed to cool to crisp, brittle, reschen and slightly fragile consistency.

Other waffle products are already baked in their final form in wafer ovens or machines, as e.g. for poured 7-sachets, waffle cups, waffle slices, lower hollow wafers and more. Like. Applies.

For the production of other waffle products, liquid waffle dough is baked to a variety of crispy, brittle leaves, which are then cooled, coated with cream and stacked in a waffle block. The cream-filled waffle block is cut into individual small, equally sized, handy pieces, which then individually or packaged several, usually airtight packaging, come on sale.

The different types of weapon product may be filled with different fillings, such as, depending on the product. Ice cream, various creams, chocolates, etc., and filled or unfilled with different coatings, e.g. made of sugar or chocolate, coated.

Of these crunchy and brittle waffle products just described, those soft wafers are to be distinguished, which are usually baked by the housewife in waffle iron and which are a soft, fluffy pancake-like baked product with a residual moisture content of more than 8 % . These soft waffles, for example, made by the housewife have no similarity in terms of their consistency and in terms of their consistency and in terms of their usability with the crunchy and brittle described above

Waffle products of the wafer industry.

Known wafer baking machines are equipped with a plurality of juxtaposed baking tongs that pass a dough pouring station, pass through a heated baking chamber, past a wafer removal station and back to the dough pouring station. During their circulation, the baking tongs are opened at the wafer removal station, folded after the Teigaufgießstation and guided in the closed state through the oven. To prepare the waffles liquid waffle dough is introduced at the Aufgießstation with open baking tongs in their Waffelbackformen or applied to the Teigbehandlungsflächen, then the baking tongs are closed, with the waffle dough distributed in the respective Waffelbackform, and the closed baking tongs passed through the oven baking space, said the Verv / eilzeit in the oven or the passage time through the baking chamber of the baking time 'corresponds to the respective waffles.

At the waffle removal station, the baking tongs are opened again and the baked waffles are removed from the open baking tongs.

There are Waffelbackmaschinen or Waffelbacköfen known in which the baking tongs go through in a horizontal plane on a circular path an annular baking space.

In other Waffelbacköfen or Waffelbackautomaten the baking tongs are connected to an endless baking tongs chain, which passes through an elongated, cuboid baking chamber in two superimposed horizontal planes in opposite directions and runs in the Waffelentnahmestation and the Teigaufgießstation outside the oven. The wafer removal station and the Teigaufgießstation are mostly in the area of the front part of the

Wafflebackautomaten arranged.

In 7-pot baking machines for producing rectangular, crispy and brittle A'affeiblättern from liquid w'affelteigen with a very low or no sugar content are the Waffelbackformen in the baking tongs except for the engraving, eg for the TCaffelmuster, essentially as a flat These baking plates can be self-supporting and thus an integrated component of the baking tongs or the baking tongs halves and can carry stiffening ribs on the back side, but the baking tongs or baking tongs halves can also be provided with a supporting frame in which usually less rigid The rectangular dough treatment surfaces of the two baking plates of a baking tongs form in the closed, folded state of the baking tongs a very low parallelepiped-shaped baking space for a wafer leaf, which laterally closes on the sides of the rectangle by closing strips In each case opposite each other usually provided with steam outlet channels end strips are solidified on the upper and lower back plate. For example, the baking space for a vailel leaf enclosed by the baking plates is 290 mm long, 46O mm wide and exclusive engraving depth is 0.5 to 3 mm high and including engraving 2 to 6 mm high.

Waffle bacl cautomaten are usually equipped with 36 to 250 identical baking plates in 18 bia to 125 same baking tongs. After prolonged periods of operation, the dough treatment sides of the baking plates of the waffle baking machines are freed of encrustations which form over time. For this purpose, after the cooling and turning off of the whole ".Vafer baking machine either the baking plates were successively removed, cleaned and reinstalled or the baking machine at one

This type of cleaning of the Teigbehandlungsseiten the baking plates is cumbersome and very time consuming and leads to long downtime of otherwise fully automatic for the entire 3etriebszeit V / affelbackautomaten.

In the case of V / affine baking machines for the production of rolled sugar, eg. For example, it is known to bake high-sugar liquid vinegar doughs between the baking plates, baking tongs of an endless baking tongs chain, wafers, or wafers, which can be formed in a hot state, and which are sharply delimited only on part of their edges remove the baked Y / apple leaves or cakes with open baking tongs from one of the baking plates and, while still warm, into hollow wafers, z, B. Bags to roll, which then take on their characteristic crispy, brittle consistency when cooling. In such a V / affine baking machine, in the region of the path of the baking tongs associated with the open baking tongs, a device is provided for pressing the wafers against that baking plate of the baking tongs, from which the respective leaf is to be removed. This pressing device is equipped with a, to the flat dough treatment surface of the respective baking plate parallel, only one side mounted pressure roller, which can be replaced by a brush for cleaning these dough treatment surfaces. With this brush only that baking plate or dough treatment surface is cleaned, from which the respective Jaff eleven loading is removed and therefore does not on the Teigbehandlungsfläche projecting, the laterally sharply defined edge region of the 7 / affelfladens forming end strip or the like. For the cleaning of such dough treatment surfaces, it is also known to arrange a brush aligned parallel thereto at a specially provided location of the baking oven for the production of rolled veal bags.
