Creation of the multifunctional chemicalreactors, where the gas heat-carrier is not used, without mixing devices and seals inthe working volume, without stagnant and difficultly washed out zones is one of waysfor improvement of quality and purity of an obtaining product, maintenance ofprofitability and ecological safety of manufacturing small-scale chemistry. Only suchthe multifunctional equipment, allowing to carry out all technological process in onevolume, will enable to create on their base flexible chemical engineering systems(FCES), capable without realignment and with high efficiency to make the widenomenclature of products [1,2].We have developed the vibrating multifunctional chemical reactor, allowing tocarry out in one reacting volume, in any sequence, without depressurization andcontact to environment almost all chemical engineering processes, namely:dissolution, synthesis, crystallization, filtering, washing, distillation, vibrating fluidizedbedconductive drying, extraction, crushing etc. [3- 9]. Basic differences of themultifunctional chemical reactor consist in a way of leading of energy for stirring - inthe form of the adjustable low-frequency harmonic vibrations brought to the workingvolume from the outside. There are no mixing devices and seals in the chemicalreactor. The working chamber is autonomic, easily removable, has an elementarygeometrical form, without stagnant and difficultly washed out zones. Drying is carriedout by conductive way in fluidized-bed. Vacuum drying through filtering knot excludescarry-over of a solid phase. The gas heat-carrier is not applied. The reactor designexcludes even potential sources of an impurity and pollution of an obtained product,provides hydrodynamic similarity of course of technological processes and theirscaling for volumes of the working chamber to 160 litres.At necessity, the internal surface of the working chamber can be made absolutelycorrosion-resistant - from fluorine plastic. Analogues of the development are absent.The development is patented in the Russian Federation.354
