A powder feed assembly comprises a powder hopper, a motor, an auger housing, an auger, a porous gas-permeable powder filter, a carrier gas inlet, an auger sleeve, and a powder hose. The auger housing receives a powder from the opening in the hopper floor into a powder chamber defined in the auger housing. The auger is selectively rotatable to propel the powder from the powder chamber past the distal end of the auger and into the auger sleeve. The carrier gas inlet introduces carrier gas into an inner chamber of the auger housing. The wall of the auger sleeve allows at least some of the carrier gas to flow or permeate into the internal bore of the auger sleeve to pick up and carry the propelled powder out of the auger housing. The powder hose directs the carrier gas and carried powder from the auger housing to a powder dispenser.

A char removal pipe including a removal pipe (22), a perforated plate (26) that partitions the interior of the removal pipe (22) into a powder channel (29) and a gas chamber (30), and an assist gas supplying device (28) that supplies an assist gas to the gas chamber (30). The perforated plate (26) is formed so that the pressure loss when the assist gas flows from the gas chamber (30) to the powder channel (29) through the perforated plate (26) is greater than the pressure loss when the assist gas flows through accumulated powder formed by the accumulation, on the perforated plate (26), of powder flowing in the powder channel (29).

A system includes a standpipe for receiving a flow of solids therethrough, the standpipe having at least one inlet configured to receive a gas for decreasing a solids-to-gas ratio of the flow, a sealpot having an inlet fluidly coupled to the standpipe and an outlet fluidly coupled to a riser, the sealpot being configured to fluidize the solids received from the standpipe and to transport the solids to the riser, and a drain device fluidly coupled to an outlet in the standpipe, the outlet being located upstream from the inlet of the sealpot. The drain device is configured to remove the excess gas from the flow of solids within the standpipe to increase the solids-to-gas ratio of the flow prior to the solids entering the sealpot.

In one embodiment, a feed system for distributing fluidized feed material, comprises: a distribution unit configured to fluidize feed material; and a control unit fluidly coupled to the distribution unit, wherein the control unit comprises: a chamber configured to hold the feed material provided from the distribution unit; and a feeder unit fluidly coupled to the chamber: and a second gas inlet configured to provide gas to the chamber; and a material discharge pipe fluidly coupled to the chamber and the second gas inlet.

A powder conveyor has a pneumatically actuated dense phase powder pump and a pressure controller. The dense phase powder pump comprises at least one conveyor chamber having a powder inlet valve and a powder outlet valve. The pressure controller can be used to adjust and maintain a set pressure on the at least one conveyor chamber of the dense phase powder pump that is or can be previously defined and/or to adjust and maintain an actuation pressure on the powder inlet valve or the powder outlet valve that is or can be previously defined. The powder conveyor further comprises a gas flow detection device for detecting or determining a quantity of gas that is fed or removed per time unit when the set pressure is adjusted and maintained on the at least one conveyor chamber or a quantity of gas that is fed to the powder inlet valve or the powder outlet valve per time unit when the actuation pressure is adjusted and maintained. An evaluation device compares at least one detected or determined gas flow value with a corresponding set value and automatically generates an error and/or alarm signal when a deviation is detected.

This powder transport device comprises: transport pipe (11) that can transport powder by way of gravity by having a prescribed angle of inclination; a porous plate (12) that is disposed along the transport pipe (11) so as to divide a line cross section into a top section and bottom section and form a powder line (11d) in the top section; an inert gas supply line for fluidization (13) that is provided under the porous plate (12) and supplies an assist gas (g) to the powder line (11d) through the porous plate (12); and a deposit status monitoring device (20) that constantly monitors the state of the powder deposited on the top face side of the porous plate (12) in the powder line (11d).

A transfer system for soft gels is disclosed. It comprises: a blower, having a first air inlet and a first air outlet, and generating an airflow by inhaling air from the first air inlet and discharging air out of the first air outlet; a hopper, having a top opening to catch soft gels manufactured and dropped directly from a soft gel machine and a bottom opening to drop the soft gels; a transfer hose, having a first opening connected to the first air outlet and a second opening, wherein a side-cut opening is formed to connect to the bottom opening, the airflow from the first opening blows the soft gels dropped at the side-cut opening to move the soft gels toward the second opening; a cooling module, having a second air inlet and a second air outlet, cooling down the external air from the second air inlet and discharging the cooled air from the second air outlet; and a connecting hose, connecting the second air outlet and the first air inlet.
