The technology described herein generally relates to an automated packaging apparatus and system that packages loose particles into a conical container as well as the final folded packages. More specifically, loose plant matter, such as crumbled dried leaves, are supplied to successive paper cones. The apparatus packs the crumbled leaves into the cones, closes the wide top portion of the cone into a precise shape, and then runs a quality control check to ensure that the final filled cone meets preset specifications.

A method of automatic packing of comminuted silicon includes providing an inner bag in a first shaping vessel, spreading out an opening of the inner bag and positioning the opening above a lip of a first filling funnel of a filling unit, and filling the inner bag with comminuted silicon. The comminuted silicon passes through the filling funnel into the inner bag. The inner bag is welded in a welding unit. The opening of the inner bag is folded together by inward folding of two opposite inner bag sides such that two inner bag edges formed by the folding-together are opposite and parallel to one another and form a fold with a channel. A vacuum welder is applied to the fold and welds the inner bag. The inner bag is transferred into an outer bag. The outer bag is welded.

The present document presents a system and a method for packaging powders in containers (S) through a hopper (T) and a first tube (TC) connected to the hopper (T). Air is sucked both in the area of the first tube and in the area of the hopper. The powder is then drawn directly from inside the hopper thus keeping the flow rate and the degree of compacting of the system constant. Moreover, the powder sucked inside the first tube is thus compacted and can be conveyed compacted towards the outlet. In this way it is possible to control the dosing of the product exiting from the system with high precision.

This invention relates to an apparatus and method for vacuum packaging drilling fluid additives and is particularly effective for low bulk density material. Vacuum sealing technology is employed to decrease the volume of the additive, thereby enabling packaging of larger quantity of additive per bag, effective utilization of storage space and reduced transportation costs. The invention overcomes the drawback of conventional vacuum packing machines where the material being packaged drifts out of the packaging bag into the vacuum chamber on vacuum creation and further deposits on the sealable portion at the open end of the bag leading to ineffective sealing of the bag opening. The apparatus of the invention is modified to increase the headspace between the sealing element of the apparatus and drilling fluid additive being sealed, thereby eliminating the movement of the additive into the vacuuming chamber and deposit on the bag opening.

The present invention relates to a blowing device (1) for blowing gas through a gas-permeable tubular-shaped packaging material (29). The blowing device comprises at least one gas nozzle (19; 75, 77), adapted to blow gas from an outside of the tubular-shaped packaging material through the tubular-shaped packaging material, and a guiding member (3), which comprises a web passage (5) having a surface (7) adapted to face the tubular-shaped packaging material, such that the web passage surrounds or substantially surrounds the tubular-shaped packaging material. The present invention further relates to a use of the blowing device, to a sealing arrangement (27, 71) for transversely sealing a gas-permeable tubular-shaped packaging material (29) and to an arrangement (37) for manufacturing of pouched products (39), which arrangement comprises such a sealing arrangement. The present invention also relates to a method for transversely sealing a gas-permeable tubular-shaped packaging material and to a method for manu facturing a pouched product, e.g. a portion-packed pouched oral snuff product.
