  • Publication number: 20160128343
    Abstract: A method for producing a baked product includes producing a baked product preform having a substantially closed baking surface and an open-pore separating surface, applying a liquid to pasty hardenable mass to the separating surface, optionally applying the liquid to pasty hardenable mass to pores being open to the separating surface, pressing the separating surface covered with the mass onto a temperature-controlled surface, and sealing the separating surface by actively, thermally hardening the mass on the temperature-controlled surface. The baked product made from the baked product preform and the hardened mass is removed from the temperature-controlled surface.

  • Publication number: 20150289524
    Abstract: A method for the continuous production of roll wafers having a short texture, includes applying a shortenable baking mass to a moving heated baking surface to form an endless baked strip, baking the baked strip substantially dry during the movement, then at least partially removing the baked strip in a hot plastic state from the baking surface and feeding the baked strip to a rolling apparatus, winding the baked strip around a rolling mandrel in the rolling apparatus and forming the baked strip into an endless hollow tube, and filling, coating, spray-coating and/or bringing the baked strip and/or the hollow tube into contact at the same time, before or afterwards with a shortening agent for shortening.

  • Publication number: 20120275260
    Abstract: A mixing device has a frame, a cylindrical mixing container that is open toward the top, and a single-shaft agitator. A vertical agitator shaft extends into the mixing container from beneath. The agitator is an agitator without a stator and includes a rotor body arranged just above the container bottom in the mixing container. The rotor body is surrounded by a ring-shaped clearance between the rotor body and the container wall. Above the base plate fastened to the agitator shaft, the rotor body is provided with an inner clearance above the agitator shaft, mixing blades vertically arranged about the clearance, and flow channels arranged between the blades. The channels are delimited toward the top by a cover plate that is connected to the upper edges of the mixing blades. The cover plate is formed with a void arranged in the center and above the inner clearance.

  • Patent number: 7754268
    Abstract: The invention proposes replacing the sugar partially or completely by erythritol and/or xylitol in baking mixtures or doughs for non-perishable baked goods made from flours and/or starches, which baked goods are deformed after the baking step in the still plastic state or in the state which has become plastic again by reheating, for example by wrapping, rolling, pressing, stamping, embossing, bending, folding or deep-drawing, the content of erythritol and/or xylitol when the sugar is completely replaced being from 12 to 55% by weight, in particular from 13 to 50% by weight, based on flour and/or starch.

  • Publication number: 20060057269
    Abstract: The invention relates to a method for producing objects, at least parts of which are a glossy brown. In a first step, an at least par-baked, dimensionally stable shaped body is produced, said body is treated as a dimensionally stable pre-product in a second step at least partially with lye. The intermediate product thus obtained can be sprinkled with a granular topping in an additional step. In the final step, the intermediate product is subjected to renewed thermal treatment, in order to brown the areas treated with lye and optionally reduce the moisture in its interior.

  • Patent number: 6187363
    Abstract: A baked product in the form of waffles or wafers can be made from a mass which is comprised of flour, oils, fats and lecithin-containing additives, and water by baking in a baking mold, on drum or belt. At least a partial substitute for the lecithin containing component is monostearyl citrate which is added and is effective to facilitate separation of the product from the baking surface.

  • Patent number: 6146573
    Abstract: Disposable, thin-walled molded articles, such as cups, plates, fast-food packages, trays, flat sheets and the like are produced by applying a starch-based baking composition onto the lower mold part of a multi-part, preferably two-part mold, and by baking and conditioning the composition to a moisture content of between 6 and 22% by weight. The baking composition, in addition to water and a starch or starch mixtures and/or flour or flour mixtures and/or starch derivatives, contains a fat-free or oil-free release agent and, optionally, other typical additives. Polyvinyl alcohol is added to the baking mixture in quantities of 0.5 to 40% by weight, relative to the starch component. The polyvinyl alcohol has a degree of polymerization of over 1000, preferably over 1600 and in particular over 2000, and the proportion of water is 100 to 360% by weight, relative to the starch component. Polyvinyl alcohol can be added either in dry form or in the form of an aqueous solution.

  • Patent number: 5711908
    Abstract: With a process for manufacturing compostible thin-walled molded articles such as cups, plates, fast-food packagings, trays, flat sheets and the like, by applying a starch-based baking composition on the lower part of a multipart, preferably bipartite mold, to obtain a tough, durable article of high mechanical stability by using an essentially fat-free baking composition composed of water, a starch product, a release agent, and optionally further conventional additives, by baking the baking composition filling the mold, and by conditioning the resulting product to establish a moisture content of 6-22% by weight, the invention proposes the use, in addition to or instead of starch, of at least one modified starch selected from the group comprising starch esterified with organic acids or phosphoric acid, etherified starch, cross-linked starch and starch capable of being modified by ionic interaction.

  • Patent number: 5576049
    Abstract: This invention relates to a process applying a water-repellent and/or waterproof coating to at least one side or the inside of shaped elements, which are obtained in that starch-containing compositions are baked between two mould halves or are extruded. That process is characterized in that a lacquer which in addition to one or more low-boiling solvents which are miscible with water and are innocuous from the aspect of human and/or ecotoxicology and one or more rottable film-forming substances and one or more rottable hydrophobic plasticizers is applied and during the application of said lacquer the adsorbed water of hydration is removed from the surface layer of the shaped element which is to be coated, whereafter the solvent mixture is removed which a minimum moisture content from 5% by weight to one at which there is no odour maintained in the substrate.

  • Patent number: 5376320
    Abstract: To produce rottable thin-walled shaped bodies, such as cups, plates, trays, and the like, which have a high mechanical stability, in a baking process which is similar to that used to produce edible wafers, it is proposed in accordance with the invention to use a substantially fat-free baking composition, which in addition to water contains as a major component a high-starch product, preferably a starch, and as release agents contains fatty acids having chains of medium or long length and/or their salts and/or their acid derivatives. In addition to said compounds or to replace them in part or sometimes entirely it is possible to use polyhydrogensiloxanes. The baking compositions may also contain thickening agents, fillers, humectants, coloring materials, structure-consolidating agents, preservatives and antioxidants. The baked products are finally conditioned to adjust them to a moisture content from 6 to 22% by weight.
