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 object of the invention is a horizontal paddle dryer that is used for normal or vacuum drying of soaked substances that are in the form of dry powder mixtures or granulates in a manufacturing process and are soaked and mixed (normally with solvents) due to technological needs. Once drying is completed, the interior of the dryer needs to be washed due to various types of substances that differ from each other in content and properties. The construction of the horizontal paddle dryer of the invention allows simple and effective washing of the horizontal paddle dryer without an additional removal of washing heads during the washing of the dryer. The horizontal paddle dryer of the invention has a specially shaped interior wall (1) of the drum (2) that passes on the upper part through two surfaces (1a, 1b) that extend tangentially to the interior wall (1) into a horizontal final surface (1c) of the internal wall (1), such that a slightly concave part is created in the interior of the drum (2) in the wall (1), in which concave part retractable washing heads (3) are arranged that do not hinder functioning of the rotor (4) with paddles (5) either during drying or during washing.

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.

The present invention relates to combined cooker and dryer apparatus to use for drying material, such as raw material for producing fish or meat meal. The device of the present invention provides a cooker and a dryer apparatus with disks and scrapers for heat exchange and evaporation of the water phase from any material.

The present invention relates to an apparatus for treating mixed waste, for example, an apparatus for degrading bioplastic material in the mixed waste. The apparatus includes an electromagnetic wave emitter adapted to emit an electromagnetic wave on to the mixed waste; a movement inducing device adapted to move the mixed waste when the electromagnetic wave is being emitted onto the mixed waste such that the mixed waste is moved to increase the exposure of the mixed waste to the electromagnetic wave; and at least one of a heat emitter adapted to emit heat and a moisture emitter adapted to emit moisture onto the mixed waste. The present invention further relates to a method of treating mixed waste.

The present invention relates to a new device and a way to assemble such a device for both cooking and drying organic material in the process of making meal. The device of the present invention has a large area for heat exchange and scrapers which stir the material in the container rather than transferring it around in circles. The method of assembling the device allows an accurate and convenient assembly so that the scrapers thoroughly scrape all inner surfaces of the device.

The present disclosure provides a bottom drying type sludge drying device, comprising: a housing in which a curved-face partition is provided for separating space in the housing into first and second drying chambers; a feed gate and an outlet provided on an upper portion of the first drying chamber, and a discharge gate provided on the circumferential wall of the first drying chamber. An inlet is provided on a side wall or bottom of the second drying chamber. The curved-face partition comprises a depressed area in which a communication opening is formed, and a bridge-shaped element is provided above the communication opening, forming a lateral aperture between the bridge-shaped element and the partition. A sludge stirring assembly is provided in the first drying chamber, which comprises a rotary shaft and a stirring unit fixed on the rotary shaft, and the stirring unit is configured to cut, break and stir the sludge and/or that a front end thereof faces and is close to the lateral aperture, such that the front end scrapes the sludge in or at the communication opening as the stirring unit rotates. The present disclosure further provides a method of drying sludge using a sludge drying device.
