A dispersion device is provided, including a container and a porous dispersion structure. The container has a first receiving space. The porous dispersion structure has at least three porous dispersion layers and has a second receiving space, wherein the porous dispersion structure is located in the first receiving space of the container.

A compression device, means for controlling the compression device, a drum having an inner chamber, means for rotating the drum, and first and second delivery devices for delivering first and second materials into the inner chamber of the drum while the drum is rotating. The compression device compresses the first and second material in the inner chamber of the drum while the drum is rotating about the center of the drum in response to the means for controlling the compression device. The apparatus may include a stirring device; and a means for controlling the stirring device; wherein the stirring device is configured with respect to the drum so that the stirring device can be moved up and down to a desired depth within the drum and rotates within the inner chamber of the drum to stir the first and second materials in the drum while the drum is rotating.

A method for preparing solid microcapsules, comprising the steps of adding under agitation a composition C1 comprising at least one active material to a cross-linkable liquid composition C2, the active material is not an additive to be used in the lubricant, fuel or bitumen industries, drilling sludges or muds, or oil exploration/production, compositions C1 and C2 being immiscible with each other. A first emulsion is obtained comprising droplets of composition C1 dispersed in composition C2, adding under agitation the first emulsion to a liquid composition C3, composition C3 and composition C2 being immiscible with each other, to obtain a second emulsion comprising droplets dispersed in composition C3. Loading the second emulsion in a mixer which applies a homogeneous controlled shear rate to said second emulsion, said shear rate being from 1 000 s-1 to 100 000 s-1, to obtain a third emulsion comprising droplets dispersed in composition C3, and cross-linking the droplets so that solid microcapsules dispersed in composition C3 are obtained.

A filtering and ventilating mechanism is driven by motors. The filtering mechanism rotates and presses downwards so its pressing surface is against a sample container. A ventilation needle is inserted into the sample container for ventilation. A mixing mechanism is arranged below the filtering mechanism and is driven by a mixing motor. The sample container is accommodated in a seat and is driven by the mixing motor. A test tube carrying mechanism is arranged below the mixing mechanism, and has an accommodating hole for a test tube. A jacking mechanism is arranged below the mixing mechanism, and is driven by a jacking motor. When the jacking mechanism moves upwards, a jacking platform is pressed against the bottom of the test tube, so that the test tube is butted against the bottom of the sample container, and a sample preparation in the sample container is dripped into the test tube.
