Intellectual Property India Publishes Patent Application for Pneumatic Material Conveying System And Method

MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202617084074 A) filed by Maricap Oy on July 08, 2026, for Pneumatic Material Conveying System And Method.

Inventor includes Sundholm, Gran.

The application for the patent was published on August 14, 2026, under issue no. 33/2026.

Abstract: A pneumatic material conveying system (1) comprising a first gravity chute (4) which is fluidly connectable to a partial-vacuum generator (3), the first gravity chute (4) comprising a number of first input points (6) via which a first material fraction is arranged to be fed into the first gravity chute (4), and arresting means (8) arranged between two first feed apertures (7) of the first input points (6). The arresting means (8) has two positions, a first position, in which the arresting means (8) extends into the channel space (5) of the first gravity chute (4) and prevents the displacement of the first material fraction fed from the first feed aperture (7) higher up past the arresting means (8) in the channel space (5), and a second position, in which the arresting means (8) allows the displacement of the first material fraction past the arresting means (8) in the channel space (5). The pneumatic material conveying system (1) comprises a second gravity chute (15), which is fluidly connectable to the partial vacuum generator (3), the second gravity chute (15) comprising a number of second input points (17) via which second material fraction is arranged to be fed into the second gravity chute (15), a connecting channel (22) fluidly connecting the channel space (5) of the first gravity chute (4) to the channel space (16) of the second gravity chute (15), an air duct (19) connected to the channel space (16) of the second gravity chute (15) for ventilating the channel space (5) of the first gravity chute (4) and/or for conducting make-up air into the channel space (16) of the second gravity chute (15) and into the channel space (5) of the first gravity chute (4) via the channel space (16) of the second gravity chute (15) and the connecting channel (22).
