The utility model discloses a dual breast grain preparation facilities, micro - injector in the device is arranged in on the accurate syringe pump, the both ends of solution siphunculus respectively with micro - injector, the breast grain generates pipe sealing connection, temperature -controlled tube II is fixed on the fixed bolster through anchor clamps, fixed bolster fixed connection is at thefixed station right -hand member, the fixed positioning channel section that is provided with in the fixed station the left side, the cup inslot of draw -in groove is arranged respectively in to wasteliquid cup and dispersion cup, hold the solidification solution that is used for the solidification of dual breast grain in the dispersion cup, it exports with the water injection to be provided withthe water injection entry respectively on temperature -controlled tube I and the temperature -controlled tube II. The export external diameter that the breast grain generated the pipe needs the closecheck, and the export external diameter is different can to produce not unidimensional dual breast grain. Ball support cuts pole fixed connection with the handle through the breast grain. The utilitymodel discloses can do you realize that the PVA layer is even, and be the diameter of narrow distribution jumbo size more than 1500 mu m solid the production preparation of the dual breast grain of liquid. The utility model discloses a device easy operation is convenient, and easily control is convenient for wash.
