Abstract
A device for preparation of liquid marbles that has a belt conveyor for carrying a layer of solid particles, the belt conveyor being provided, successively in the direction of movement of the belt with at least one solids dispenser with a reservoir for solid particles, at least one liquid dispenser with a reservoir for liquid, and a separator for separating the prepared liquid marbles from solid particles, is disclosed.
Claims19
A device for preparation of liquid marbles, characterized in that it comprises a belt conveyor (1) for carrying a layer of solid particles, said belt conveyor (1) being provided, successively in the direction of movement of the belt, with at least one solids dispenser (2) with a reservoir for solid particles, at least one liquid dispenser (5) with a reservoir (7) for liquid, and a separator for separating the prepared liquid marbles from solid particles;
- wherein the liquid dispenser comprises a pump;
- and wherein the pump is selected from a syringe pump, a pump with a syringe, a piston in a heated block, a pneumatic pump, a linear pump, a peristaltic pump, a centrifugal pump, a gear pump, a spindle pump, a single-channel or multiple-channel dispense solenoid valve, a diaphragm pump, a vane pump, a pneumatic pump, a hydrostatic pump, a screw pump, and a dosing valve.
A method of producing liquid marbles comprising the step of a device comprising:
- a belt conveyor (1) for carrying a layer of solid particles, said belt conveyor (1) being provided, successively in the direction of movement of the belt, with at least one solids dispenser (2) with a reservoir for solid particles, at least one liquid dispenser (5) with a reservoir (7) for liquid, and a separator for separating the prepared liquid marbles from solid particles.
A method of producing liquid marbles, said method comprising the steps of:
- providing a device comprising:
- a belt conveyor (1) for carrying a layer of solid particles, said belt conveyor (1) being provided, successively in the direction of movement of the belt, with at least one solids dispenser (2) with a reservoir for solid particles, at least one liquid dispenser (5) with a reservoir (7) for liquid, and a separator for separating the prepared liquid marbles from solid particles,
- continuously applying a layer of solid particles to a moving belt conveyor (1) by means of at least one solids dispenser (2),
- applying droplets of liquid to this layer by at least one liquid dispenser (5) to at least partially coat the liquid droplets with the said solid particles,
- transferring the said at least partially coated liquid droplets into a separator in which their coating by solid particles is completed, if needed, to form liquid marbles,
- separating the produced liquid marbles from the excess solid particles on the basis of their different sizes.
