Abstract:
The invention relates to a valve flap (1) for producing a casting machine valve (100), in particular for installing into a casting machine for casting a flowable substance, in particular a liquid substance with suspended solid particles, such as chocolate for example, in which cocoa particles and sugar particles are typically suspended in a molten fatty substance that has cocoa butter and milk fat to a greater or lesser extent. The valve flap is designed such that a valve can be produced with at least one other valve element, said valve consisting in particular of at least two valve flaps (1) that are preferably identical.

Abstract:
The invention relates to a method and device for separating a mixture made of particles of a first particle type and a second particle type, especially aleurone particles and shell particles made of comminuted bran, said particles being scarcely distinguishable in terms of size and density, into various types of particles. Separation occurs according to particle-type specific triboelectric charging of said particles in a first active area and subsequent separation of the differently charged moving particles in an electric field.
Abstract:
The invention relates to a method for the production of granulate grains of polymers from thermoplastic polyesters or copolyesters from a polyester melt using an extrusion granulator. The polyester melt is fed to nozzles of the extrusion granulator and then, with draw-in rollers, to the granulation device via an extraction section as extrusions exiting from the nozzle, wherein, e.g., an extrusion extraction speed is set by the draw-in rollers. The invention also relates to an improved extrusion granulator according to the invention having a wave device between the nozzles and the extraction channel, and granulate grains produced according to the method according to the invention.
Abstract:
The invention relates to a method for producing soybean flour consisting of soybeans. said method comprising the followving steps: a) the soybeans are husked to a husking degree of more than 97%; b) the husked soybeans are ground to a particle-size distribution whereby more than 60% of the soybean particles measures between 50 μm and 0.5 mm and more than 30% of the soybean particles (fine part) measures less than 50 mm. by subjecting the same to a percussive force; c) an enzyme system of the soybean particles is deactivated and the soybean particles are agglomerated; and d) the agglomerates comprising the deactivated soybean particles are finely ground to a particle size distribution whereby at least 98% of the particles is smaller than 100 μm by subjecting the agglomerates and the deactivated soybean particles thereof to shear forces. The invention also relates to a soybean flour that is preferably produced by the inventive method, the maximum particle size being smaller than 100 μm, the soybean enzyme system having been at least partially deactivated by heat. and the husk content being less than 0.3 wt. %
Abstract:
The invention proposes the damping of grain, for example, by creating a rotating layer (20) in a damping chamber (2) with the help of acceleration rotors (3). For this, the cross-section of the rotation chamber is designed to form an outer boundary around two or, preferably, three acceleration rotors (3, 3', 3"). In this way, the rotating layer is forced into an eccentric and spiralling motion within the damping chamber (2). Damping is carried out in a very gentle manner, so that there occurs hardly any abrasion and no grain damage. Additional advantages include a longer and controllable reaction period during damping, optimized preparation for milling and a shorter, controllable tempering period.
Abstract:
The invention proposes a novel automatic product feed in which an analog signal is formed and at least one other digital signal which is adjustable independently of the analog signal is generated and used for the automatic product feed for supervising the product feed functions by a mechanical probe (8) in the product flow. In this way, all previously known controlling and regulating functions can be realized with a minimum of electronics or at the highest level of computer control as a function of the product feed or for optimizing the grinding conditions, possibly with externally initiated digital signals for various stage adjustments and with the use of very simple automatic component means. The invention further proposes a corresponding method for grinding with a milling roller mill (1).
Abstract:
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.
Abstract:
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.
Abstract:
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.
