A batch sample preparation apparatus (10) for preparing a geological sample for analysis is described and claimed. The apparatus (10) comprises a dryer (12) having a drying (chamber 52), a sample inlet (20) and at least one sample outlet (22), (24) communicating with the drying chamber (52), to a comminution device (14) in selective fluid communication via valves (26), (28) with the dryer (12) to selectively receive dried sample. The apparatus (10) has a source of fluid (74) introduced at the dryer (12) so that sample material may be transported from the dryer (12) to the comminution device (14) by fluid flow, which fluid flow also extracts the sample material from the comminution device (14) for collection and subsequent analysis.

The system for drying lignite according to the present disclosure includes a mill configured to crush the lignite; a dryer configured to receive crushed lignite from the mill, to dry the lignite by heat-exchange with steam and to discharge dried lignite; a condensing-precipitating evaporator in fluid communication with the dryer so as to receive vapor which is evaporated when the lignite is dried, and which is discharged from the dryer. The evaporator is configured to condense the vapor discharged from the dryer by heat-exchange with water. The coal dust contained in the vapor is precipitated into a condensed aqueous solution when the vapor is being condensed, and the condensed aqueous solution is discharged. The system includes a Mechanical Vapor Re-Compression (MVR) configured to receive steam generated from the condensing-precipitating evaporator, to compress the steam into superheated steam, and to supply the compressed superheated steam to the dryer.

The present invention relates to an improved food waste dryer utilizing waste heat, which includes a main frame, a dryer drum with an access door, to be positioned in the main frame, and an agitator positioned in the dryer drum. The improved food waste dryer comprises: a waste heat supply unit, a heating jacket positioned on the outer surface of the dryer drum, with a hot-air inlet to receive the waste heat from the waste heat supply unit and a hot-air outlet to discharge the waste heat inside the dryer drum, and a condensation system positioned in the main frame, to remove moisture included in the interior air of the dryer drum to increase the drying efficiency of the food waste dryer utilizing waste heat.

The present invention relates to a centrifugal pellet dryer comprising a housing accommodating a rotor surrounded by a screen, wherein said screen includes at least one porous screen member and is supported by a screen support holding the screen relative to the housing. To avoid vibrations and noise, the centrifugal pellet dryer has the screen supported against the housing by a screen support which includes at least one damper for dampening vibrations of the screen and/or isolating screen vibrations from the housing.

Methods and systems for continuously bagging pellets formed from a tacky and/or polymer containing formulation include improved drying systems and techniques. The methods and systems may include directing a flow of air to help contain moisture within a dryer, transport pellets out of the dryer, and/or dry pellets as they move away from the dryer. The methods and systems may include conditioning (e.g., drying, coating, classifying) the pellets using a conditioning unit prior to bagging the pellets.
