A device for drying granules, such as those made from a plastic material. The device can have a spiral arrangement of rotor blades on a rotor to propel process fluid through a sieve and separate the process fluid from granules by having sieve openings of a size smaller than the granules. The device can also have a fan wheel and a hollow shaft to create an air flow and improve separation and drying of granules. The device enables reliable automated drying of granules using less energy than prior art devices.

A method for removing adherent or immigrated olfactory substances from thermoplastic particles which take the form of bulk material and are exposed to dry, warm air in a treatment chamber of a warm-air container during a time period. Before the treatment in the warm-air container, the plastic particles are warmed in at least one infrared rotary tube, wherein the infrared rotary tube has at least one infrared radiator device arranged in a central region of the interior space thereof and directed towards the inner wall of the drum thereof. During a time period the plastic particles are warmed while the drum is continuously rotated and after that are transferred in the warm state, with a maximum temperature loss of 20 K, into the treatment chamber of the warm-air container where they continue to be exposed to warm air during the time period.

In some embodiments, a grain drying apparatus may include a drum with a grain auger including a flighting with air holes. The drum may be surrounded by an outer drum, the inner drum including a plurality of drum air holes. A volume of dehydrated air may pass around a helical air diverter, located in an annulus between the inner drum and the outer drum, and through the grain, thereby drying the grain.

Sand and liquid that are stored within a hopper are pulled together along a trough by a set of discs that are attached to and rotate about a shaft. The trough is configured to allow the liquid to flow downwards as the sand is compacted and elevated. The discs conform to a part of the surface of the trough with enough space to allow the liquid to flow around it. This allows dry sand to exit the trough and retains the liquid in the hopper. The discs are rotated on the shaft by a belt and motor.

The invention relates to paper processing, namely the processing of a paper web or a paper web section in order to form a paper stick. The processing is carried out in multiple process stages, including storing the paper web, stretching the paper web, controlling/regulating the guide for the lateral edge, conveying the paper web, folding the paper web, rolling, adding an additive, cutting, removing the remaining paper web, separating the paper sticks, drying the sticks, and/or post-treating the sticks.
