A fluid control system in pneumatic conveying ducts of powdered or granular material, comprising: a supply source of a pressurized gas for transporting said powdered or granular material; an injection line of said gas to put said source in fluid communication with a conveying duct inside which the material is conveyed; a self-regulating pressure valve arranged on the injection line between the source and said duct; a control member of the self-regulating valve to provide a control signal to said valve representing a pressure value, said valve maintaining the gas flow supplied in said duct constant; and a flow and flow rate meter, arranged on the injection line upstream of the valve to transmit a flow and flow rate value to said control member.

In one aspect, a system for removing blockages present within a delivery conduit of a seeder may include a plurality of delivery conduits, a plurality of flow blocking devices, and a plurality of blockage sensors. A controller may be configured to determine when a blockage is present within a first delivery conduit of the plurality of delivery conduits based on measurement signals received from the plurality of blockage sensors. The controller may be further configured to control the flow blocking devices to occlude the flow of air through the other delivery conduits of the plurality of delivery conduits such that an air pressure in the first delivery conduit is increased.

A continuous production system continuously produces a product from a raw material powder. The system includes a first processor that performs a first process on the raw material powder, a second processor that performs a second process on the powder on which the first process has been performed by the first processor, and a test chamber through which the powder being sent from the first processor to the second processor passes. A cleaner blows gas from an inlet side opening formed in the inner face of a channel connected to the test chamber from the first processor on the downstream side of an inlet side gate valve for opening and closing the channel toward a direction to form a swirling flow along the inner face of the channel.

A method and a device for transporting a plurality of insects from a chamber to a location via a channel, wherein the insects are transported by means of an apparatus for producing a medium flow, and wherein a transport additive is added to the medium flow during transport, the amount of the transport additive being set in accordance with the amount of insects moved.

Material flow amplifiers as disclosed herein overcome drawbacks associated with known adverse flow conditions (e.g., surface erosion and head losses) that arise from flow of certain types of materials (e.g., fluids, slurries, particulates, flowable aggregate, and the like) through a material flow conduit. Such material flow amplifiers provide for flow of flowable material within a flow passage of a material flow conduit (e.g., a portion of a pipeline, tubing or the like) to have a cyclonic flow (i.e., vortex or swirling) profile. Advantageously, the cyclonic flow profile centralizes flow toward the central portion of the flow passage, thereby reducing magnitude of laminar flow. Such cyclonic flow profile provides a variety of other advantages as compared to a parabolic flow profile (e.g., increased flow rate, reduce inner pipeline wear, more uniform inner pipe wear, reduction in energy consumption, reduced or eliminated slugging and the like).

A module connector for holding and/or transporting of bulk goods for connecting a first container module to a second container module, the container modules being joined together have an aligned container inner surface, a first seal arranged between the first container module and the second container module, a second seal arranged between the first container module and the second container module, the first seal is arranged in a recess and the second seal in a groove, the first seal forming an inner seal and the second seal forming an outer seal, the second seal produces a sealing of the interconnected container modules especially if the first seal fails, the first seal has at least one crimp region, which is crimped by a first and/or second flange surface such that one end face of the first seal is situated flush and/or aligned with the container inner surface without forming a cavity in the area of the end face of the first seal as well as a seal element for the module connector for the sealing of the container.

Diverter assembly for pneumatic transport of a substance using a fluid flow, e.g. for transporting whey powder. A diverter main body is provided with an input pipe connection having an input flow direction, and at least one output pipe connection having an output flow direction perpendicular to the input flow direction. The diverter main body further comprises a collision wall part arranged remote and opposite from the input pipe connection and having a collision surface arranged perpendicular to the input flow direction, and a narrowing flow part shaped and arranged to provide a flow path from the collision wall part to the at least one output pipe connection.

Disclosed is a system for conveying particulate material, in which particulate material is conveyed along a conveying pipeline (117) by a flow of a conveying gas. A plurality of injector arrangements (121) are positioned along the conveying pipeline, for injecting a continuous flow of conveying gas into the pipeline. The system includes pressure differential apparatus for detecting whether a pressure differential in the pipeline between an injector arrangement and an adjacent injector arrangement is above or below a threshold value. In use each injector arrangement is operable to increase the flow rate at which conveying gas is injected into the pipeline when a pressure differential rises above the threshold value is detected between adjacent injection locations along the pipeline. The present invention provides a continuous flow of conveying gas at each of the plurality of injector arrangements, reducing the risk of blockage. Pressure differentials along the conveying pipeline are reduced. Together this facilitates stable and predictable conveying of the particulate material and reduced conveying gas usage.
