Abstract:
A carousel carries a holder with product to be dosed and includes a lower disc fitted with peripheral sets of dosing holes into which plungers insert and press in successive stages doses of product. The carousel also includes fixed bodies and radially moveable bodies with seatings for supporting tops and bottoms of capsules. Lower bodies support extensions that close the lower ends of dosing holes in the successive stages, and opposing members are provided to support the moveable assemblies. With only one dosing disc, it is possible to form doses of product of different densities and masses and of different heights by varying the heights of the sets of plungers. A chamber defined by a sweeper wall and containing no product is provided with a plunger station that completes the pressing of this final quantity of product, before a subsequent plunger station discharges the product into the capsule bottoms.
Abstract:
An ejection and conveying device mounted in a rotary pressing tabletting machine having matrices supported by a rotating table, whereinto upper punches and lower punches enter and come out, while tablets come out at an ejection station; the device includes a plate fastened to the machine and positioned under the table. Part of the plate is located under the machine's ejection station, while a rotating disk is placed inside a raised border of the plate and has a plurality of hollows whereinto the ejected tablets fall so that the tablets are drawn by the disk up to be positioned above one or more holes made in the bottom of the plate and from which holes discharge channels depart. The tablets pass through the holes and are brought away by the channels.

Abstract:
A granulator device (101) for the treatment of powdered products comprises a closed container (102) forming a chamber (103) for treatment of the products, filter elements (104, 105) projecting into the treatment chamber (103), the filter elements comprising a multi-layer filtering wall (105) through which a fluid current can pass, and powder removing parts (106; 107, 108, 109, 110) designed to diffuse at least one service fluid directed towards at least the filtering wall (105); the powder removing parts (106; 107, 108, 109, 110) having at least first diffuser nozzles (107) and at least second diffuser nozzles (108) to diffuse the service fluid so as to free the filtering wall (105) of the powders trapped in it; there also being parts (140, 142, 147) for supporting and driving the filter elements (104, 105) which can change the angle of the filter elements (104, 105) from a first operating position, in which at least the first nozzles (107) act on the filtering wall (105), to a second operating position in which the filter elements (104) are set at an angle to the first operating position to allow the second diffuser nozzles (108) to operate on the filtering wall (105).
Abstract:
In a method and related capsule filling machine for producing sealed capsules (C), each defined by a body (1) coupled with a lid (2), the capsule body (1) is filled with a quantity or dose (3) of material, especially pharmaceutical material in liquid or powder form, and the capsule (C) is closed by placing the lid (2) over the body (1) so that their respective annular ends (1a, 2a) overlap. A sealing substance is applied to at least one of the overlapped ends (1a, 2a) of the capsule body (1) and lid (2) before the capsule (C) is closed.
