Abstract
A dosing device for feeding infusion products including a dosing drum rotating about an axis and positioned between a continuous strip of filter material, movable along a feed direction, and a primary hopper for containing a primary infusion product; the dosing drum has a plurality of radial chambers for receiving a first dose of primary infusion product from the primary hopper and for releasing the first dose of primary infusion product above the strip of filter material; the device also includes an independent dosing unit of a secondary product including controlled release elements configured for depositing a second dose of secondary product to define a mixed dose of primary product and secondary product.
Claims12
A dosing device for feeding infusion products, comprising a dosing drum rotating about an axis;
- the dosing drum being positioned between a continuous strip of filter material, movable along a feed direction, and a primary hopper for containing a primary infusion product;
- the dosing drum having a plurality of radial chambers each configured for receiving a quantity of primary product forming a first dose at the primary hopper and, respectively, releasing the first dose above the continuous strip of filter material, in such a way as to form a succession of first doses, equidistant from each other, along the continuous strip of filter material, the radial chambers being movable in rotation at the primary hopper, whilst they receive the first dose and above the continuous strip of filter material whilst they release the first dose;
- wherein it comprises an independent dosing unit for feeding a secondary aromatising or sugar product designed to define a second dose and positioned downstream of the first doser relative to the feed direction of the continuous strip of filter material;
- the independent dosing unit having controlled release elements configured for placing the second dose at least partly on a corresponding first dose deposited on the continuous strip of filter material passing under the independent dosing unit to define a mixed dose of primary product and secondary product;
- the independent dosing unit comprising a channel for feeding the secondary product housing an extractor screw constituting the controlled release elements.
The device according to 1, further comprising a shaped guard, positioned downstream of the dosing drum and designed to fold the continuous strip of filter material to define a continuous tube of filter material which surrounds the mixed doses of primary product and secondary product, the shaped guard having an opening, the controlled release elements being coupled to the shaped guard at the opening, so that the secondary product moves from the controlled release elements to the continuous strip of filter material through the shaped guard.
A method for feeding infusion products comprising the following steps:
- preparing a continuous strip of filter material, movable along a feed direction;
- depositing a first controlled quantity of a primary infusion product, defining a first dose, on the continuous strip of filter material in such a way as to define a succession of first doses, equidistant from each other, by means of the dosing drum rotating about an axis;
- depositing a second controlled quantity, different from the first quantity and defining a second dose, of a secondary aromatising or sugar product, on a corresponding first dose deposited on the continuous strip of filter material in transit, by means of an extractor screw feeder to define a mixed dose of primary product and secondary aromatising or sugar product.
