Abstract: 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.

Abstract: Attached to the eccentric studs (25) for supporting and positioning press rollers (b 20) relative to an inner surface of the die (21) of a pellet mill are levers (30). Linked to the levers (30) is a cylinder/piston unit (31) that is provided with a position controller (47) whose position measuring means is constructed as part of the adjusting means (31) for the position of the press rollers (20). In this fashion, the gaps between press rollers (20) and die (21) can be regulated very exactly from the outside.

Abstract: The two feed rolls of a roll refiner comprising at least four rolls for processing viscous materials, such as chocolate masses, are regulated with respect to their rotational speeds by means of a suitable regulating system. The two feed rolls rotate in a fixed speed ratio to each other at speeds determined by the prevailing operating conditions. The particle size and/or the output quantity of the processed material may be held constant by this regulation.

Abstract: An injection unit for an injection molding or die-casting machine comprises an injection ram which injects molten material out of an injection sleeve into a mold or die during a filling phase. This injection ram is connected to a drive piston which is movable within a drive cylinder for actuating the injection ram. The whole ram unit, comprising the injection ram and the drive piston, consists of at least two parts releasably connected together. A control device for the movement of the injection ram during the different phases of injection comprises a control valve. A signal transfer arrangement is interconnected between this control valve and the ram unit which is provided with a damping arrangement so that its releasably connected parts are movable relative to each other.

Abstract: In an infrared measuring apparatus for the continuous quantitative determination of individual components of flour or other groundable food products in a tubular measurement segment (24) with forced transport (27) of the material to be measured, equipment (29, 31, 32, 33, 34) is provided for consolidating the material to be measured in the region of a sensor (20) for the measurement of the consolidated material. In the corresponding measurement process, the groundable product is passed over a measurement segment (24), a slight compression and smoothening of the groundable product being achieved in the region of the sensor (30).

Abstract: An agitator mill has an arrangement for diminishing the pressure of the attritive elements towards the outlet. This arrangement comprises particularly means for generating a force pointing away from at least one separator opening forming a passage for the product, but retaining the attritive elements within the milling container. This force affects substantially selectively only the attritive elements. According to one embodiment, this force acts upon the attritive elements in counter-direction to the direction of flow of the product. The force may either be a centrifugal force acting selectively onto the relative large mass of the attritive element or a magnetic force acting selectively upon steel balls, iron balls or the like used as attritive elements.

Abstract: A centrifugal force separator for broken grains, husks, dust and other impurities from air has a pre-separating chamber (2) with a tangential raw gas inlet (1), in which a cylindrical deflecting screen (4) and a clean gas outlet (5) axially adjoining the latter are concentrically arranged. To increase the degree of dust separation at only a slight pressure loss and in the case of an inexpensive construction, and also to enable application in return-air systems in combination with other cereal crop cleaning and processing machines, a pre-separating chamber (X) for an air circulation is provided radially outside the deflecting screen (4), and an air discharge (Y) is provided radially inside the deflecting screen (4), which air discharge (Y) is in flow connection with the pre-separating chamber (X) via air passage channels (17) in the deflecting chamber (4).

Abstract: A pellet mill comprises a die which may rotatably be driven by a suitable drive. At least one press roller engages the inner surface of this die, and material to be pelleted is fed to this press roller by means of a deflector blade situated before. This deflector blade is arranged at least 45.degree. before the related press roller--as seen in the direction of the rotation of the die--so that a free space of at least 45.degree. will result therebetween. Within this free space, the centrifugal force due to the rotation of the die becomes effective and contributes to a better distribution of the material.

Abstract: In a die-casting or injection molding machine transducers are provided for generating a signal corresponding to the injection pressure as well as a signal in accordance with the velocity of the ram device, i.e. the injection screw or the injection piston of the machine. The output signals of these transducers are supplied to a calculating stage for calculating the actual injection power. The resulting signal at the output of the calculating stage is fed to an evaluation device, preferably comprising an indicating device, but also a control circuit, if desired.

Abstract: The process serves for closing filled bags (52) making use of an approximately horizontal conveying track (3). The bags are fed on a conveying track with constant conveying speed to a spreading apparatus (16 to 51) and then to a closing station (12, 13). In order that the bag material be stressed as little as possible in the case of a greater capacity, provision is made for a movement to be superimposed on the spreading tools (21) of the spreading apparatus during the spreading process, in the conveying direction (4), that attains the conveying speed, at latest, at the end of the spreading process. In this fashion, the bag end is spread apart without the bag experiencing a delay by the spreading tools (21) reaching therein.

Abstract: For dressing, seed is thrown off in dispensed doses into a trough-shaped rotary table (36) in the form of a free-falling annular veil. During its freefall, the seed is guided through a jet of dressing in the form of an annular surface, which is thrown outwards from the interior of the annular veil and which is generated when dressing is thrown out via a centrifugal plate (36), and is wetted with dressing. During the subsequent throwing out on the rotary table (9), the seed is subjected again to dressing which is finely distributed on and massaged into the grain surface because the seed grains roll on the rotary table (9) continuously and at the same time strike against one another and rub on one another.

Abstract: A roller mill, in which the milling rollers are pressed together with high pressures, has a fluidic device for imparting the respective pressure. This fluidic device comprises piston-cylinder units and a pressure line for the fluid. In order to obtain a skewing of at least one roller in dependency upon the pressure exerted by the fluidic device, pressure sensitive means are interposed between the pressure line and a displacing device for the skewing angle. In this way, a pressure signal may be transferred to a converter for converting the pressure into a corresponding displacement stroke. Preferably, at least one roller has a basic camber or crown which corresponds to a pressure within a lower range of the occurring pressures.

Abstract: FIG. 2 illustrates a process and an apparatus for controlling a controllable magnitude as well as the use of the process, especially for controlling the throughput of pourable or flowable material (grain or water) in a flour mill. In this connection, a servo drive, constructed as a fluidic pressure drive (5', V'), is provided for controlling a servo element. The deviation, measured by a comparator (1'), is supplied to a discriminator (10), which then gives off a first discrimination signal (+U.sub.F, -U.sub.F) when the deviation has reached a first (lower) or second (upper) threshold value, the two threshold values lying within a range of small deviations about zero. In this range of small deviations, the pressure drive (5') is acted upon by transient micropressures (rapid pressure fluctuations with small peak values), the reversal points of the microfluctuations depending on the two aforementioned threshold values.

Abstract: A separating contrivance for separating cereals and similar grain product into at least three grain fractions and heavier impurities comprises two air-penetrable fluidized bed tables (2, 3) arranged one over the other and supported in fashion capable of being oscillated in relation to a frame, with a product inlet (9) leading to the upper fluidized bed table. At one end of the contrivance, and spaced away from the inlet (9), the upper fluidized bed table (2) is provided with outlets (10, 18) for the light and medium heavy grain fractions, while the lower fluidized bed table (3) includes outlet (27) for the heavy grain fraction. Adjoining the other end of the lower fluidized bed table (3) is an outlet (16) for the heavy impurities such as stones and the like. In order to achieve a practically complete sorting of the heavy impurities, provision is made so that the two fluidized bed tables (2, 3) are supported independently of one another and are driven by separate oscillating drives (7, 25).

Abstract: The invention describes a new type of automation for a roller carriage. The amount of product conveyed to the roller carriage is constantly subject to fluctuations, and is determined by a mechanical probe. A corresponding signal directly activates a pneumatic valve, and control pressure adjusts the instantaneous performance of the grinding rolls. The pneumatic valve has a so-called zero position, and becomes a follower control device by means of servo-media and the adjusting mechanism of the performance-dependent elements in the roller carriage. At the same time, the control pressure in the pneumatic valve can start and stop the grinding rolls.
