CONTINUOUS MANUFACTURING OF SPRAY-DRIED POWDERS
The present invention relates to a method of manufacturing spray-dried powders. During the process, a solvent is used. The process is done in a continuous manner and such that the emulsification mass ratio is low when removal of the solvent is started. Preferred solvents are isopropyl acetate and ethyl acetate. The invention also relates to a set-up to run the inventive process at industrial scale.

METHOD FOR PRODUCING BIS(FLUOROSULFONYL)AMIDE ALKALI METAL SALT POWDER
An object of the present invention is to provide a method for producing a bis(fluorosulfonyl)amide alkali metal salt powder having high purity while suppressing reduction in yield due to thermal decomposition, etc. The method for producing a bis(fluorosulfonyl)amide alkali metal salt powder according to the present invention comprises precipitating a bis(fluorosulfonyl)amide alkali metal salt by conducting distillation using a thin-film evaporator while adding a poor solvent for the bis(fluorosulfonyl)amide alkali metal salt such as an aromatic hydrocarbon solvent and a linear or branched aliphatic hydrocarbon solvent to a solution formed by dissolving the bis(fluorosulfonyl)amide alkali metal salt in a good solvent for the bis(fluorosulfonyl)amide alkali metal salt such as an ester solvent and nitrile solvent.
SYSTEM AND METHOD FOR MULTI-FUNCTIONAL SLURRY PROCESSING
A multi-functional slurry processing system (“VARCOR”) and associated methods is disclosed. The present examples provide a multi-functional slurry processing system incorporating systems and methods for separating liquid and solid components in slurries. In particular the systems and methods described herein produce clean water, dried solids, and potential concentration of desirable constituents with a boiling point lower than water. At least one example of the multi-functional slurry processing system provides a self-contained processing facility configured to efficiently convert high water-content slurries into its constituent solid and liquid fractions and subsequently generating and collecting clean water and concentrating desirable constituents with a boiling point lower than water. The multi-functional slurry processing system advantageously applies thermodynamic principles in a system which may include various combinations of a preheater, a degassing unit, a dryer, a steam filter, a compressor, a concentrating tower, and a condensation unit.

TANDEM EVAPORATION-DRYING METHODS AND SYSTEMS FOR MAKING POWDERED MILK-DERIVED PRODUCTS
Methods of making a powdered milk product are described. The methods may include providing an aqueous milk-sourced mixture, and evaporating water from the aqueous milk-sourced mixture to produce an evaporated milk-sourced mixture having a total solids concentration of 35 wt. % or more. The evaporated milk-sourced mixture may be dried to form the powdered milk product, which may have less than 6 wt. % water. Systems for making the milk powdered product are also described. The systems may include an evaporator to evaporate water from a supply of a milk-sourced mixture to form an evaporated milk-sourced mixture. They may also include a dryer to dry the evaporated milk-sourced mixture and atomize it into the powdered milk product.
