| 摘要 |
The invention relates to a method which includes separately conveying a first liquid solution (36) and a second liquid solution (40) in a double shell (32). The invention includes forming a series of drops (78) at the outlet of the double shell (32), each drop (78) including a central core (80) made of a first solution (36) and a peripheral film (82) made of a second solution (40). The method comprises dropping each drop (78) into a gaseous volume at the outlet of the double shell (32) and submerging each drop (78) in a gelling solution (70) in order to form a gelled shell. The ratio of the kinetic energy of the drop (78) to the square of the radius thereof, when said drop comes into contact with the gelling solution (70), is greater than 1 J/m2. |
