Spray drying method and systems are disclosed that include one or more single-use components. Single-use spray drying systems can include a drying chamber with an inner surface formed of a polymeric material. The single-use components can be pre-sterilized and sterile packaged to provide improved efficiencies and greater flexibility in spray drying systems.

A method for controlling a prilling bucket in the prilling of a a urea melt (UM) including: feeding the urea melt to a prilling bucket (1) which vibrates under the action of a magnetostrictive device (2), wherein the vibration of the bucket is controlled, as a function of the amount of urea melt to be prilled, by the following steps: acquisition of a time-varying input signal (3) which represents the flow rate of urea melt fed to the prilling bucket; generation of a first signal (5) and of a second signal (6), independently from each other, as a function of said input signal (3); generation of a third signal (10) having a frequency which is modulated by said first signal and an magnitude which is modulated by said second signal, and use of said third signal to drive said magnetostrictive device (2).

A process for PAI-based coating compositions. An embodiment of a method includes manufacturing a coating composition, the manufacturing of the coating composition including mixing a first solvent, the first being solvent being N-formyl morpholine (NFM), with a second solvent to form a first solution; dissolving polyamideimide or polyamide amic acid resin polymer (PAI) in the first solution; precipitating a PAI compound from a mixture of MEK and the first solution; and dissolving the PAI compound in a second solution to generate a coating solution.

A facility for industrial drying and/or encapsulation of thermolabile substances comprising at least one injection unit (1) wherein the thermolabile substance is introduced, an encapsulating material when the facility is used to encapsulate, a solvent, additives and an injection gas flow for obtaining droplets from the thermolabile substance. It further comprises a drying unit (2) through which the droplets and a drying gas are introduced for evaporating the solvent and comprises a collection unit (3) configured to separate the microcapsules generated from the drying gas and which is selected from a cartridge filter collector, a cyclone collector or a combination of the two. It also describes a method for the industrial encapsulation of thermolabile substances which is carried out at the proposed facility.
