The preparation prepared has good emulsifying and dispersing effect of adapalene, can be expanded on a large scale, and the industrial promotion prospect is good.

There is provided an apparatus and a method for producing a play compound and the play compound itself which, in one embodiment is a compound which sufficiently fluid to be pliable and is typically cold and slimy to the touch. The apparatus and a method provide a powder and liquid to a user, which can be a non-skilled person and thereby allow the mixing of the powder and liquid together by that person to form the play compound outside of a factory environment whilst ensuring that the play compound which is formed has the desired characteristics. Most typically the user which performs the mixing can be the end user, such as a child, who will play with the compound and so the formation of the play compound forms a new part of the play experience.

A dynamic wetting head with which polymers are prewetted and mixed. The prewetted and mixed polymers are typically used in the process of polymer flooding during chemical enhanced oil recovery. The dynamic wetting head comprises a prewetting unit and a mixing unit. The prewetting unit has a feed spigot provided in communication with a source of powder and projecting at least partially into a wetting chamber of the prewetting unit. The feed spigot feeds polymer powder into the wetting chamber. Furthermore, at least a first spray nozzle sprays water into the wetting chamber. The mixing unit comprises a mixing chamber with an inlet provided in communication with the wetting chamber outlet, a feed water inlet, and an outlet. A mixer is furthermore arranged within the mixing chamber.

An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the as collected condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (e.g., mixture of soil, vegetation, and/or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and/or chemical properties of the sample. The preparation sub-system may comprise a slurry recirculation flow loop configured with devices to stir, measure, and adjust a water to solids ratio of the slurry.

The invention relates to an apparatus for the continuous production of a particulate adsorption product, the apparatus comprising: a mixing drum having an elongated cavity for receiving a particulate adsorbent material, an adsorbent inlet and a product outlet, wherein the mixing drum is arranged such that the cavity is inclined in flow direction of the particulate material, and wherein the cavity comprises an initial transport zone adjacent to the inlet and a mixing zone following the initial transport zone; a rotating member extending through the cavity in a longitudinal direction, wherein the rotating member comprises a helical conveying blade at longitudinal positions corresponding to the initial transport zone and mixing instruments at longitudinal positions corresponding to the mixing zone; and one or more injection nozzles for injecting a liquid adsorbate to the mixing zone. The invention further relates to a process for the continuous production of a particulate adsorption product using such apparatus.

An apparatus configured to process foodstuff materials can include an exterior tube, an inner shaft, and multiple differently shaped protrusions. The exterior tube can have a foodstuff inlet, an outlet, and a longitudinal axis, and can be configured to facilitate the conveyance of foodstuff materials along a material passage from the foodstuff inlet to the outlet. The inner shaft can be located within the exterior tube, can extend along the longitudinal axis, and can combine with the exterior tube to define the material passage. The inner shaft can be configured to be rotationally driven. The multiple differently shaped protrusions can be coupled to and extend from the inner shaft, and these differently shaped protrusions can be configured to process the foodstuff materials when the inner shaft is rotationally driven.
