    • The present invention relates to an apparatus and method for manufacturing solid particles based on inert gas evaporation, where the method comprises forming a continuous gaseous feed flow comprising a saturated vapour of the material, and injecting the continuous gaseous feed flow through an inlet into a free-space region of a reactor chamber in the form of a feed jet flow protruding from the inlet, and forming at least one continuous jet flow of a cooling fluid and injecting the at least one jet flow of cooling fluid into the reaction chamber, wherein the feed jet flow is made by passing the feed flow at a pressure above the reactor chamber pressure in the range from 0.01 · 10
      5 to 20 · 10
      5 Pa through an injection nozzle functioning as the reactor inlet and which has a rectangular cross-sectional area of the nozzle opening with height A
      feed and width B
      feed , where the aspect ratio B
      feed /A
      feed is ≥ 2: 1, and the height A is in the range from 0.1 to 40 mm, and each of the at least one jet flow of cooling fluid is made by passing the cooling fluid through an injection nozzle which directs the jet flow of cooling fluid such that it intersects the feed jet flow with an intersection angle between 30 and 150°, and where each of the at least one jet flow of cooling fluid, either individually or combined, mixes with substantially all of the gas of the feed jet flow at an intended distance apart from the nozzle opening for injection of the feed jet flow.
    • 本发明涉及一种用于制造基于惰性气体蒸发的固体颗粒的设备和方法,其中该方法包括形成包含该材料的饱和蒸汽的连续气体进料流,并且将该连续气体进料流通过入口注入到自由 - 从进口突出的进料射流形式的反应室的空间区域,并且形成至少一个连续的冷却流体射流并且将所述至少一个冷却流体的射流注入所述反应室,其中所述 进料射流是通过使进料流在高于反应室压力0.01×10 5至20×10 5 Pa的压力下通过用作反应器入口的注射喷嘴进行的,并且该注射喷嘴具有矩形横截面积 的高度A进给和宽度B进给,其中高宽比B进给/ A进给≥2:1,并且高度A在0.1至40mm的范围内时, 由于冷却流体的一股射流通过使冷却流体通过喷射喷嘴而形成,喷射喷嘴引导冷却流体的射流使得它以30°和150°之间的交叉角与进料射流相交,并且其中每个 至少一个单独或组合的冷却流体射流流动与基本上所有的进料射流流动的气体混合,离开用于喷射进料射流的喷嘴开口的预定距离。
