The invention relates to a device (1) for filling open bags (2) with powdery food, comprising a support structure (3) and a filling spout (4) accommodated on the support structure (3), on which a bag (2) to be filling is suspended. The bag (2) is maintained on the filling spout (4) by means of a bag holder (5, 6). The support structure (3) comprises a hollow profile (10, 11) with a control component (20) accommodated therein in order to protect against soiling. The hollow profile (10) comprises an air outlet (8) for controlling, in the hollow profile (10) when in operation an air pressure higher than the environment.

Packaging machine and method for filling dusting product such as bulk material into open-mouth bags via a filling process. The filling process is controlled by weight via a control device and a weighing device. A batching element conveys product and introduces it through a filling spout into an open-mouth bag appended for the filling process. The filling spout is connected with a collecting tank through a flow connection such that a pressure surge occurring during the filling process is utilized for transferring into the collecting tank the displacing air contained in the open-mouth bag and including the dusting product to receive and settle the displacing air in the collecting tank and to deposit at least part of the dust content of the displacing air in the collecting tank as deposited product.

There is disclosed a system for dispensing granular material, comprising: a nozzle attached to a granular filler configured to couple with a trefoil filling port attached to a can for hot isostatic pressing, wherein the nozzle opens and closes via a rotary actuation. In an embodiment, the system comprises a single fill port design, such as one having a concentric, tube-in-tube design. There is also disclosed a method of filling a container with a granular material, by connecting a filling nozzle to a filling port, opening/closing the filling nozzle, attaching the filling nozzle to the filling port, aligning at least one opening of the filling nozzle with an opening in the filling port; and dispensing granular material into the container.

The invention relates to a connecting device (2) for connecting a container (F) containing a powder/granular product to an isolator (1) with a connecting opening (120), through which the container (F) is introduced into the isolator (1) for emptying as intended, wherein the connecting device (2) comprises: a holding device (220) being configured to receive the container (F) and hold it during connecting and emptying; a transfer device (210, 230) for transferring the holding device (220); and a control device for controlling the transfer device (210, 230); wherein the control device is configured to control the transfer device (210, 230) in such a way that it transfers the holding device (220) together with the container (F) from an initial holding position in which the container (F) is received in the holding device (220) as intended, into an emptying position such that at least an opening of the container (F), via which the powder/granular product is removed for emptying the container (F) as intended, is introduced into the isolator (1) through the connecting opening (120).

The invention relates to an isolator (1) for emptying a container (F) containing a powder/granular product, the isolator (1) comprising: a connecting device (1) for connecting a container (F) containing a powder/granular product to the isolator (1); a base body (100) which defines a connecting opening (120) via which an opening of the container (F) can be introduced at least in sections into an inner space of the base body (100) from an outside environment as intended wherein a lower ambient pressure is generated in the inner space of the base body (120) than in the outside environment, and wherein the connecting device (2) comprises a sealing device (250) arranged at the connecting opening (120) and having an adjustable sealing element (251) which can be adjusted in such a way that it
is pressed against an outer wall of the container (F) to produce a sealed state and closes the inner space from the outside environment, and
is released from the outer wall of the container (F) to produce an at least partially open state in such a way that a gap (S) is formed between the sealing element (251) and the outer wall of the container (F), wherein the gap (S) is formed in such a way that an air flow directed into the inner space of the base body (120) is generated due to the different ambient pressure.
