摘要:
The apparatus and methods of the present invention are of use for the production of emulsion-based microparticles containing a biological or chemical agent. In particular, the apparatus provides a vessel; packing material situated inside such vessel and may further provide material capable of insertion into both ends of said vessel for enclosure of the packing material. In a particular embodiment, the apparatus is a packed bed apparatus. The methods include production of emulsion based microparticles containing a biological or chemical agent. The usefulness of the present invention is that the apparatus and methods of the present invention provide for a low-shear, non-turbulent, production of emulsion-based microparticles that provides a narrow, reproducible, particle size distribution, capable of use with both large and small volumes that is capable of being conveniently scaled up while providing predictable emulsion properties.

The invention relates to a carbonator (4), preferably an inline carbonator, mounted on the pressurised liquid outlet (11), preferably on the diaphragm pump (3) in order to carbonate degasified beer, preferably with CO 2 . The pump (3) is preferably driven by at least one 12 volt motor (35). The motor (35) is supplied with energy via the mains supply circuit (37). The energy supply can be variably routed to the motor (35) via the mains supply circuit (37) in various stages, influencing the speed of the motor (35) and the pump pressure of the pump (3). The pump (3) is also preferably a suction pump and can draw the liquid to be carbonated, preferably degasified beer, from a bag-in-box container.

A system (21) and process for ultrasonically treating a liquid having a thermal conductivity, an elongate treatment chamber housing (55) has an inlet (69 a, b) and an outlet ( 65) such that liquid f lows longitudinally through an interior space ( 53 ) of the chamber from the inlet ( 69a, b) to the outlet (65). At least part of the interior space (53 ) of the chamber housing is filled with a bed of particles (24 ) having a thermal conductivity substantially greater than that of the liquied whereby a ratio of the thermal conductivity of the particles to the thermal conductivity of the liquid is in the range of about 2 : 1 to about 400 : 1. An elongate ultrasonic waveguide assembly (101) extends longitudinally within the interior space ( 53 ) of the housing and is operable at a predetermined ultrasonic frequency to generate mechanical ultrasonic vibration within the housing in direct contact with the liquid flowing therein as the liquid flows through the bed of particles.

A foam generating system (10) utilizes a positive displacement pump (24) to deliver liquid at a substantially constant liquid delivery rate to a foam generator (14). The liquid delivery rate is independent the pressure of air supplied by a pressurized air source (18) to the foam generator (14), the back pressure of the foam generator itself, the volume of liquid in a supply tank (28), and the pressure drop of the connection line (L) from the foam generator to a user appliance (A). The foam generator (14) delivers foam at a constant foam delivery rate (expressed as weight of foam per unit time) to the user appliance (A). The liquid supply tank (28) is vented to atmosphere.

An apparatus for preparing foam for incorporation into cementitious slurry comprises a conduit having an inlet for receiving a gas feed and a surfactant feed, and an outlet for allowing the exit of foam. The conduit houses a porous plug that provides a partial barrier to fluid flow along the conduit, the plug comprising a plurality of particles that are packed in a regular array and that define a three-dimensional network of pores extending therebetween. The apparatus comprises a resilient component located between the plug and the conduit.

Disclosed is a micro bubble generation device. The micro bubble generation device comprises: a rotating unit which receives a mixture of water and gas that flow thereinto, enables the water and the gas to be rotated by colliding with each other, and discharges the dissolved water; a dissolution tank which stores the dissolved water that is discharged from the rotating unit; and a nozzle unit which receives the dissolved water that flows thereinto, and generates micro bubbles in the water. Thus, micro bubbles having the dimension of 100nm or less can be generated in large quantities by using low power.
