A method for producing resin particles includes drying resin particles in a wet state by passing, without circulating, the resin particles through a drying tube together with a first gas, the resin particles being ones that undergo pressure-induced phase transition. The drying tube has an inlet through which the resin particles are fed into the drying tube, at least one gas blowhole through which a second gas is blown over the resin particles passing through the drying tube, and an outlet through which the resin particles are ejected from the drying tube, and the second gas is blown out of the gas blowhole at a velocity of 50 m/s or more.

There is provided an apparatus for use in drying a sample of geological material having a substantial moisture content. In one aspect, the apparatus comprises a means for providing a flow of heated fluid, and a means for managing the thermal state of the flow of heated fluid. The means for managing the thermal state of the flow of heated fluid is arranged operable with the means for providing a flow of heated fluid so that exposure of the sample to the flow of heated fluid facilitates a reduction of the moisture content of a portion of the sample while substantially preserving one or more chemical and/or physical properties of the portion.

A vortex dryer for fibrous material utilizes a helical inlet to the base of a central vortex tube to separate fiber from debris by abruptly changing direction of the conveying air flow. The dryer combines the helical input with helical shaping of the air flow through the central vortex tube to induce greater drying for the fiber which is continued at the top of the vortex tube through a separate drying chamber.

A fluid product dryer and related methods. Implementations of a method for drying particles may include: introducing particles through an inlet into a first fluid bed section; migrating the particles onto a bed deck; injecting a gas towards the particles through openings in the bed deck; migrating some of the particles through a variable-sized gate opening between the bed deck and a riser; migrating a portion of the particles into the riser; propelling the portion of the particles in the riser upwards by an injection of a gas into the riser; directing a first fraction of the portion of the particles out of the first fluid bed section and into a second fluid bed section through an outlet using a deflector feature; and directing a second fraction of the portion of the particles onto a bed deck of the second fluid bed section by interaction with an impingement feature.

A method of processing steel grit may include moving steel grit into a pre-classifier, weighing the pre-classifier with steel grit being processed by the pre-classifier, and altering a functional process to process the steel grit based on the weight of the pre-classifier including the steel grit. A machine for processing steel grit may include a pre-classifier configured to process steel grit to remove debris from the steel grit. A support member may be configured to support the pre-classifier. Multiple rotatable link assemblies may connect the pre-classifier to the support member to enable the pre-classifier to freely rotate as a function of gravity when supported from the support member. A weight sensor may be configured to weigh the pre-classifier including steel grit contained in the pre-classifier.

The invention relates to a method for grinding and drying a material or material mixture (M), using a cyclone device (10) which communicates with an outlet line (52) for gas (G) and material (M) processed in the cyclone device (10), wherein at least a portion of the gas (G) and material (M) in the outlet line (52) are returned into a lower opening (14) of the cyclone device (10) for further cyclone treatment. The invention relates also to an apparatus.

The present disclosure relates to methods and systems for concentrating a solids stream recovered from one or more process streams derived from a beer in a biorefinery by exposing the recovered solids stream to an evaporator system to remove moisture therefrom and form a concentrated, recovered solids stream.

The invention relates to an evaporation dryer (1) for drying particles, having—a process chamber (10) with at least one product inlet (11) for supplying the particles to be dried into the process chamber (10) and a product outlet (12) for discharging dried particles from the process chamber (10), —a heat exchanger (20) arranged within the process chamber (10), —having at least one inlet (21, 211) into the heat exchanger (20) for pressurized steam as process steam and at least one condensate outlet (22, 222) from the heat exchanger (20), wherein—the at least one condensate outlet (22, 222) is connected to an expansion tank (30), wherein at least one pump (40) is connected to the expansion tank (30), and the expanding steam is pumped out of the expansion tank (30) and supplied to the process steam.
