摘要:
The invention relates to the production of pasta, particularly pasta made of gluten-free raw materials such as flour and/or semolina based on maize, rice, millet or barley or starch, wherein the method comprises the following steps: a) preparation of a raw material-dry mixture; b) incorporation of water into the raw material dry mixture while the raw material is moved in order to obtain a dough or a moistened raw material mixture; c) incorporation of steam into the dough, during which the dough or moistened raw material mixture is moved; d) forming of the dough thus obtained in order to create defined dough objects; and e) drying of the formed dough objects in order to form pasta.

The invention concerns a novel process and a device for stabilizing the shape of both long and short pasta. A small amount of water, e.g. 0.4% to 1.2%, is added to the surface of the product while it is still hot in a water addition member (27) at the end of the drying or climate zone (9) and the product is then cooled in a cooling arrangement (29). The pasta are then stacked in the traditional manner for stabilizing insofar as this is required for the subsequent packaging process. In this way, subsequent cracking which was previously often unexplained can be avoided even when very extreme drying climates and short drying periods are used.
摘要:
The inventive method and apparatus suggests guiding the pasta directly into a drying climate after exiting from the die. Pasta strands of short goods are fed directly into the drying device from the extrusion die. The pasta strands can be cut either directly at the extrusion die or subsequently into packaging lengths after drying by means of an additional cutting device. It is possible to operate only the initial drying in this way, particularly to heat up the goods and then to carry out the final drying in a manner known per se, e.g. by portions. However, it is also possible to carry out the drying in its entirety, i.e. the pre-drying and final drying, according to the invention, particularly for short goods. The goods can be intensively dried at previously unaccustomed temperatures of 90.degree. C. to 120.degree. C., particularly during final drying from 15% to less than 13% product moisture. Further, it is preferably suggested to provide a cutting device for the pasta strands directly at the die, by means of which short as well as long goods substantially of packaging length can be cut. When the packaging length of the long goods must be cut accurately, a second cutting device can be provided after drying, which allows a particularly great flexibility of the installation for the production of different products ranging from longer goods to the shortest goods.

Apparatus for production of long pasta products has a press, a movable bar hanging arrangement from which the products are suspended and a drier. The drier is constructed as a single level drier with a rapid heating zone and an intense drying zone. The rapid heating zone has several different climate zones of differing temperatures, and fresh and exhaust air ducts. The intense drying zone has a plurality of ventilated elements. The drier includes a climate controller for each climate zone. The rapid heating zone and intense drying zone are formed as a circulating system for fresh and exhaust air. Inside the drier, air flow is zonally controlled and directed, in each element, from top to bottom or bottom to top. A supplemental air system is provided for the plurality of ventilated elements. At least part of the circulating air is blown in as in a turbo system.

The new invention proposes a new method and a device for the production of dough, particularly for pasta. The formation of dough from the dry raw materials to the finished pressed products is effected in a very short time in two stages. A raw dough is first produced in a 2-shaft mixing kneader; this dough has a substantially complete protein structure. The forming of the dough, including the mixing of the raw materials, takes place by means of an interplay of kneading and shearing, but without extrusion die pressure at the end of the first stage. In the case of classic pasta, the dough which is produced in pieces by the short 2-shaft mixing kneader is transferred to a long single-shaft press and pressed with high pressure to form the desired shapes.

A description is provided of a process for producing long products with a moisture content of less than approximately 14% by weight and particularly approximately 11 to 13% by weight, the long product leaving the press head in the form of soft, moist-plastic dough strands being guided in suspended manner up to the final drying through varyingly heated climate zones and at the end of the drying process, the long product is cooled and/or dimensionally stabilized in a further climate zone. The long product leaving the press head is heated as rapidly as possible in a first climate zone, but in more than 10 minutes to a temperature of more than approximately 80.degree. C. under the action of a heating medium with a relative humidity of approximately 60 to 80% and then in a second climate zone under the action of a drying medium with a temperature of over approximately 80.degree. C. and a relative humidity of approximately 65 to 85% is dried to a moisture content of less than approximately 14% by weight, or to avoid undesired reactions over approximately 80.degree. C. initially to a moisture content of less than approximately 18% by weight and then at a lower temperature to a final moisture content of less than approximately 14% by weight. This process can be performed extremely rapidly and supplies high-quality products. It can be performed with particular advantage in a single-level drier for drying the long products (FIG. 1).
摘要:
A process is described for manufacturing of farinaceous products in which the soft farinaceous product leaving a molding head is conveyed through differentially heated climatic zone and is cooled and/or dimensionally stabilized after completion of the drying process. The farinaceous product is heated to a temperature of 80.degree. to 100.degree. C. with at least slight initial drying and freshly expanded superheated steam is then allowed to flow around it for about 30 seconds to 20 minutes. In this process the native starch of the boundary layer of the farinaceous product is converted into swelling starch. Finally the farinaceous product is dried in a controlled drying climate.

The protein framework is developed in a continuously working 2-shaft kneading device for the production of paste product dough without--as was previously required--a dwelling time of 10-15 minutes in a mixing trough. In so doing, a so-called dry and crumbly dough is formed. This is transferred to a directly adjoining single-shaft screw press without the application of pressure if possible. The apparatus accordingly includes three characteristic process stages: a first whirling mixer for the intimate mixing of the dry components with water, a 2-shaft kneading device, and a single-shaft press.
摘要:
A process and an apparatus for cleaning pasta presses, particularly for the "in situ" cleaning of the screws of screw-type machines, kneader mixers and the like in the pasta industry. This is effected without dismantling the machine by conveying cleaning liquids through the screw-type machines which are closed in liquid-tight manner. The cleaning liquids are preferably recycled and filtered.
摘要:
The invention concerns a method for producing pasta in which the amount of starch that can be digested in the gastrointestinal tract is less than 50%, said method involving the following steps: a) introducing a dry, raw material mixture, which contains starch and protein and comprises flour and/or semolina, together with water, steam and at least one active ingredient into a closed, forced-conveyance reactor, in which mixing produces a moistened raw material mixture which is then subjected to alternating stress by kneading and working under the effects of temperature and pressure during a predetermined dwelling time in the reactor, in order to partly convert the starch into a broken-down or swellable state and together with the protein and the active ingredient to form a matrix that penetrates the pasta thus obtained; b) shaping of the pasta thus obtained into defined pasta shapes; and c) drying of the shaped pasta shapes to produce a pasta product.
