A method and an apparatus are disclosed for processing plastics, in which the material in incoherent solid state is dehumidified in a hopper and is then melted in an extruder, after which the molten material is used in a moulding device for moulding by injection and/or by blow moulding and/or compression, and in which a set point pressure value of the molten material is set on the basis of a measured residual humidity value of the dehumidified incoherent solid material, so as to decrease the pressure value by a preset variation value if the measured residual humidity value is lower than a reference value and to increase the pressure value by a preset variation value if the measured residual humidity value is higher than said reference value.

A seed flow chamber for handling seed and grain commodity, especially for use with a seed treatment applicator. Seed flow is received through an upper inlet opening configured to receive a flow of seed and discharged through a lower discharge opening. A diverging guide member splits the seed flow. A converging guide member disposed below the diverging guide member reunites the seed flow prior to discharge. The converging member has a downward sloping surface and an air vent, such as a plurality of airflow apertures connected to a plenum. The air vent is configured to communicate with an air supply. A vacuum vent—disposed below the diverging guide member—is configured to communicate with a vacuum source. A fan system recirculates air between the air vent and the vacuum vent. Dehumidifier may condition the air supply to assist with drying.

A device and method for drying fine particulate. A parallel flow rotary drum dryer is used to dry the particulate material. There is a combustion chamber for the burner, located upstream of the dryer inlet, and the burner flame is limited to the combustion chamber so the fine particulate material does not come into direct contact with the burner flame. The output from the dryer passes through a knock-out box including a baffle system with a plurality of narrow gaps to create a pressure drop to slow down the gas flow and enable the entrained fine mesh dry particulate to drop out through a bottom outlet before the effluent gas is sent to the dust collection/air filtration system.

An improved grain dryer is presented having a mixed-flow heating section having a plurality of inlet ducts connected to the plenum that facilitate air flow into the grain column from the heated and pressurized heat plenum, and a plurality of exhaust ducts connected to openings in the exterior wall that facilitate air flow out of the grain column. Outer most ducts of the inlet and exhaust ducts, which are positioned closest to end walls of the grain column, are configured to reduce bridging or grain between the outer most ducts and the end walls of the grain column.

There is a grain aeration system for a grain bin. The system includes a gas entry duct configured to receive gas and a gas distribution pipe extending upwardly from the gas entry duct and having a height. The gas entry duct extends along a base of the grain bin. The gas distribution pipe includes a permeable section and an impermeable section. The permeable section includes a plurality of perforations. The permeable section is above the impermeable section. There is also a grain bin, having a surrounding wall and roof. There is a gas entry duct extending from outside the surrounding wall to inside the surrounding wall and a gas distribution pipe extending upward from the gas entry duct. The gas distribution pipe has a permeable section above an impermeable section.

A process for drying granular polymeric material, comprising the steps of: dehumidifying the granular polymeric material by means of a first flow of gas at a first temperature of between 100° C. and 150° C.; heating the dehumidified granular polymeric material to a second temperature, greater than the first temperature; drying the granular polymeric material heated to the second temperature, by applying a predefined vacuum level; and transferring the dried granular polymeric material to a feed hopper (40) provided upstream of a working machine (100).
