Abstract: A sieve is disclosed for use in a plansifter. The sieve can be changed between backwire and combined sieve configurations without the height of the sieve changing, and while maintaining contact between a frame of the sieve and the sieve box. A dynamic combined cleaner also is disclosed in which the center of gravity of the cleaner dynamically changes based on inertial movements applied to the cleaner.

Abstract: A control apparatus, particularly for roller mills in plants for milling food products, including a probe device which is inserted in a container of a product to be fed to a pair of milling rollers by feed rollers. The device includes a reference probe, which is always immersed in the product and measures a reference capacitance value, and a level probe, which measures a variation of the capacitance of the product related to the variation of the level of the product. The reference capacitance value and the capacitance variation are used by a control means to actuate the rollers. The probe device is pre-calibrated in factory so as to be able to adapt automatically to the variations of the characteristics of the product to be fed to the rollers.

Abstract: A method for producing ethanol starting from corn flours, which provides for the milling of the corn, the separation of the light fractions (bran), a first refining of the milled fractions, a first sifting with germ separation, a second refining of the milled fractions, and a second sifting with germ separation. In particular, according to the invention, impact milling of the wet corn is provided so as to preserve the largest possible average particle size of the milled fractions, and subsequent crushing of the germ is also provided, so as to facilitate size separation thereof. With respect to known systems for producing ethanol starting from corn flours, the method according to the invention allows to extract from corn at least 7%, preferably at least 10% (by weight with respect to the initial product) of pure germ (i.e., germ not contaminated by other components) and at least 1% pure bran, preferably at least 2.

Abstract: A plansifter for separating the products of cereal milling, which includes a plurality of compartments arranged vertically, a plurality of sieves stacked in each compartment, a rotating mass assembly to keep under vibration the plurality of compartments and therefore the plurality of sieves, and flexible suspension assemblies to allow vibration. The plurality of compartments has a binary configuration, forming pairs of compartments that are symmetrical and aligned with respect to the rotating mass assembly that is arranged centrally. The plansifter allows a reduced footprint for an equal performance, allows to provide a modular construction that can be extended according to future requirements, to simplify mechanical construction and maintenance, and to distribute the flexible suspension assemblies according to requirements.

Abstract: Device for milling food products, including two separate milling passages and a sifting member (18, 19) interposed between the two milling passages. The sifting member (18, 19) includes a rotating member (18) which affects the product that leaves the first milling passage so as to propel it against a screening surface (19). The apparatus uses a plurality of devices and the method uses the device.

Abstract: The present invention relates to a particle separator device which comprises a centrifugal separator with a loading duct, a duct for discharging the agglomerated particles and a duct for the discharge of the gaseous flow. The device comprises Venturi-meter throttling means, a pressure element which has a pressure containment chamber which is preferably formed with a diaphragm which supports a movable part. A pneumatic connection is provided between the chamber and the throttling means, and a mechanical coupling is provided between the movable part and valve means for adjusting the width of the passage of the gaseous flow. The device is capable of self-adjusting according to the amount of granular material which is kept in suspension. The invention furthermore relates to an apparatus for the pneumatic conveyance of granular materials which uses the device described above.
