1. Способ десублимации твердых веществ путем взаимодействия холодного газа-носителя с десублимируемыми парами и отделения готового продукта, отличающийся тем, что проводят раздельное взаимодействие с холодным газом паров не менее двух видов десублимируемых веществ до состояния пресыщения парогазовых смесей, выдерживают смеси в зоне десублимации до достижения требуемых размеров частиц, затем потоки газ - твердые частицы смешивают послойно, направляя слои навстречу друг другу, причем слои одного потока направляют под одинаковыми углами к вертикали, а слои второго потока направляют под переменными углами.1. The method of desublimation of solids by the interaction of a cold carrier gas with desublimated vapors and separation of the finished product, characterized in that they conduct separate interaction with the cold gas vapors of at least two types of desublimated substances to a state of saturation of vapor-gas mixtures, maintain the mixture in the zone of desublimation until the required particle sizes, then the gas-solid particles flows are mixed in layers, directing the layers towards each other, and the layers of one stream are directed at the same angles to the vertical and the layers of the second stream is directed at varying angles. 2. Устройство для десублимации твердых веществ, включающее десублиматор с отверстиями для подачи пара десублимируемого продукта и холодного газа-носителя, и узлы отделения готового продукта, отличающееся тем, что устройство дополнительно содержит еще один десублиматор и камеру смешения, в нижней части которой расположены щелевые отверстия с направляющими, причем на одной стенке камеры они расположены под одинаковыми углами к оси аппарата в интервале значений 30-75°, а на противоположной стенке - под разными углами, увеличивающимися от 30 до 75°, при этом оба десублиматора снабжены паро-газораспределительными камерами с решетками и сублиматорами.2. A device for desublimation of solids, including a desublimator with holes for supplying steam of a desublimated product and cold carrier gas, and units for separating the finished product, characterized in that the device further comprises another desublimator and a mixing chamber, in the lower part of which there are slotted openings with guides, moreover, on one wall of the chamber they are located at equal angles to the axis of the apparatus in the range of 30-75 °, and on the opposite wall - at different angles increasing from 30 d 75 °, whereby both desublimator equipped with steam-gas distribution chambers with bars and sublimator.
