The invention relates to a method for preparing emulsions.

In order to create a new method for preparing emulsions, in which homogenous oil droplets as small as possible can be generated with an energy input as low as possible, it is proposed in the scope of the invention, that at least two liquid streams of liquids that cannot be intermixed with one another are pumped through separate openings with defined diameters, in order to achieve flow velocity of the liquid streams of more than 10 m/sec., and in that the liquid streams collide at a collision point in a space, wherein the resulting emulsion is discharged from the space through an outlet.

By the collision of the liquid streams with high flow velocities, in which a plate-shaped collision plate is formed in the collision point, a homogenous emulsion having an oil droplet size of less than 1 m is achieved due to the kinetic energy, which is accordingly very stable as well. No further energy input, such as shear forces, is required to that end.

The present invention relates to a new reactor for performing, by means of at least one solid reaction member, biological or chemical transformation, or physical or chemical trapping from, or release of agents to, a fluidic medium, which reactor is comprised of a reactor vessel comprising means for enhancing fluidic shear stress, and a transformation device operatively mounted in said reactor vessel. The invention also provides a kit of parts comprising a reactor vessel comprising means for enhancing fluidic shear stress and a transformation device. Finally, the invention provides a method of using said reactor and/or said kit of parts for biological or chemical transformation or physical or chemical trapping from, or release of agents to, a fluidic medium, by means of at least one solid reaction member.

Gas hydrate slurry formation systems are provided. The gas hydrate slurry formation system includes a cavitation chamber configured to receive a fluid and a cavitation device placed within the cavitation chamber. The cavitation device is configured to form a plurality of bubbles within the fluid in the cavitation chamber. The gas hydrate slurry formation system also includes a gas inlet configured to introduce a gas within the cavitation chamber such that the gas is entrained in the plurality of bubbles to form a plurality of gas-entrained bubbles. The plurality of gas-entrained bubbles implode within the cavitation chamber to form a gas hydrate slurry.

A pot lid assembly comprises a pot lid, an electric motor assembly and a mixing apparatus. The electric motor assembly is fixed to the pot lid. The mixing apparatus includes a stirring rod and a plurality of stirring vanes. The electric motor assembly includes an electric motor. The electric motor includes a rotary shaft operatively connected with the stirring rod so that the electric motor can cause the stirring rod to rotate. The pot lid is configured to cover the pot body to form a closed cooking space. When the pot lid is removed from the pot body, the rotary shaft is disengaged from the stirring rod, and the mixing apparatus can stand in the cooking space of the pot body, with the stirring vanes serving as a support. The mixing apparatus remains in the cooking space of the pot body after the removal of the pot lid.

The present invention provides methods, systems and apparatus in which one fluid passes through an orifice or orifices and mixes with another fluid as it flows through a microchannel.

A method and apparatus are provided for mixing highly viscous fluids to form a mixture. The mixture is created rapidly and has a high level of uniformity. The mixture is created by utilizing induced viscous fluid folding under the influence of an electric field. The electric field is introduced by connecting a nozzle dispensing the fluids in parallel to a voltage supply and grounding a collection plate located below the nozzle. When a certain voltage is applied the co-flow viscous fluids start to fold because the electric field exerts stress on the surface of the fluids, which results in changes of the geometry and dynamics of the viscous fluids. Control of the electric field provides great control over the mixture.
