A microparticle forming device is used to form microparticles with uniform particle size and proper roundness, and includes a collection pipe, a fluid nozzle, a reactor and a filter. The collection pipe includes a fluid passage, an aqueous-phase fluid inlet, an oil-phase fluid inlet and a mixed fluid outlet, all of which communicate with the fluid passage. The oil-phase fluid inlet is located between the aqueous-phase fluid inlet and the mixed fluid outlet. The fluid nozzle has a plurality of oil-phase fluid drop outlets aligned with the oil-phase fluid inlet of the collection pipe. The reactor has a reaction chamber communicating with the mixed fluid outlet of the collection pipe, a mixing member accommodated in the reaction chamber, and a microparticle collection port communicating communicated with the reaction chamber. Two opposite ends of the filter respectively communicate with the reaction chamber of the reactor.

Microparticle forming device

A nozzle for producing microparticles includes a nozzle body having an oscillating device and an amplifying portion connected to the oscillating device and located between first and second ends of the nozzle body. A through-hole extends from the first end through the amplifying portion and the second end. A tube assembly is mounted in the through-hole and includes first and second tubes between which a first fluid passageway is defined. A second fluid passageway is defined in the second tube. Two ends of the first tube respectively form a first filling port and a plurality of first outlet ports both of which intercommunicate with the first fluid passageway. Two ends of the second tube respectively form a second filling port and a second outlet port both of which intercommunicate with the second fluid passageway. A formation space is defined between the second outlet port and the first outlet ports.

Nozzle for producing microparticles

A nozzle for producing microparticles includes a nozzle body having a first end and a second end opposite to the first end. The nozzle body further includes a through-hole extending from the first end through the second end. A fluid passageway is defined in the through-hole and forms a filling port in the first end of the nozzle body and a plurality of outlet ports in the second end of the nozzle body. The nozzle body further includes an oscillating device and an amplifying portion. The oscillating device is connected to the amplifying portion. The amplifying portion surrounds the fluid passageway and is located adjacent to the second end of the nozzle body.
