The apparatus is constituted by at least an operating unit comprising: a chute, inferiorly associated to a hopper for containing granular or powder product, the chute being extended downwards to convey the product towards an underlying container; a rotary obturator having a horizontal axis X, for transversally occluding the chute and being laterally provided with an opening destined to place the chute in communication with a batching chamber, realized internally of the body of the obturator and delimited, on an opposite side to the opening, by a gas-permeable wall; a conduit connected at an end thereof to the batching chamber, via the wall, and at another end thereof to aspirating and blowing means; motorized organs for commanding rotations of the obturator, with which the opening is alternatingly oriented upwards, during the loading stage, in order to enable the granular or powder products, falling from the hopper and introduced into the upper part of the chute to enter the batching chamber, which is depressed thanks to the action of the aspirating means, and in a downwards direction, during the subsequent delivery stage, to enable the batched volume of granular or powder product, projected by a jet of pressurized gas generated by the blowing means, to exit the batching chamber and enter the lower part of the chute to descend towards the container.

1. An apparatus for volumetric batching of granular or powder products in a container, which comprises: a hopper for containing the granular or powder products; at least a batching chamber for receiving a predefined volume of the product from the hopper during a loading stage of the batching chamber
1. An apparatus for volumetric batching of granular or powder products in a container, which comprises: a hopper for containing the granular or powder products; at least a batching chamber for receiving a predefined volume of the product from the hopper during a loading stage of the batching chamber; a gas-permeable wall delimiting a bottom wall of the batching chamber; aspirating means for placing the batching chamber in depression, through the gas-permeable wall, during the loading stage; blowing means, activated alternatingly to the aspirating means in a subsequent delivery stage, which generate a pressurized gas jet which is injected into the batching chamber through the permeable wall and is able to project the predefined volume of granular or powder product towards the container, with the apparatus being constituted by at least a modular operating unit, characterized in that it comprises: a chute, inferiorly associated to the hopper and extending downwards, for conveying the granular or powder product towards the underlying container; a rotary obturator arranged with a substantially horizontal axis, for transversally occluding the chute, provided laterally with an opening for setting the chute in communication with the batching chamber, the batching chamber being realized internally of the body of the obturator and delimited, on an opposite side with respect to the opening, by the gas-permeable wall; a conduit, associated to the obturator and connected, at an end thereof, to the batching chamber via the permeable wall, and at another end thereof, to the aspirating and blowing means; motorized organs for commanding rotations of the obturator, by action of which the opening is alternatively oriented upwards, during the loading stage, in order to enable the granular or powder product, falling from the hopper and introduced into the upper part of the chute, to enter the batching chamber, and is alternatively oriented downwards, during the delivery stage, to enable the predefined volume of granular or powder product to exit the batching chamber and enter the lower part of the chute to descend towards the container. 2. The apparatus of claim 1, wherein the chute exhibits a vertical axis. 3. The apparatus of claim 1, wherein the chute exhibits a straight development. 4. The apparatus of claim 1, wherein the axis of the chute and the axis of the rotary obturator are perpendicular to one another. 5. The apparatus of claim 1, wherein the rotations of the obturator are each by 180°. 6. The apparatus of claim 1, wherein the rotary obturator exhibits a hemispherical head which sealingly fits into a corresponding shaped section of the chute. 7. The apparatus of claim 1, wherein the opening of the rotary obturator is arranged substantially centered with respect to the axis Y of the chute. 8. The apparatus of claim 1, wherein the batching chamber develops axially with respect to the rotary obturator. 9. The apparatus of claim 1, wherein it includes regulating organs, for modifying a capacity of the batching chamber within a predetermined range between a minimum and a maximum. 10. The apparatus of claim 9, wherein the regulating organs comprise a cursor which is axially inserted in the rotary obturator and which is adjustable into predefined positions. 11. The apparatus of claim 1, wherein the cursor solidly nears the permeable wall and exhibits an axis hole which defines the conduit. 12. The apparatus of claims 11, wherein it includes seal gaskets interposed between the rotary obturator and the cursor. 13. The apparatus of claim 1, wherein the motorized organs comprise a cogged pinion, coaxial to the axis of the rotary obturator and solidly constrained thereto, which cogged pinion is enmeshed with a cogwheel activated by an electronically-controlled motor.
