need to make granular powder from liquid which can be reconstituted...
The fluidized bed spray granulation is a method for making free-flowing granulates from liquids. It can be used in different applications in various industries, since the product properties can be varied in many ways by setting process technical parameters and configurations. The granules are suitable for making tablets and, because of their often round shape, also for final coating. Many industrial applications require converting liquid substances into a stable product form with exactly defined properties – whether for further processing as a solid for food products, animal feed or cleansing agents, for reducing the product volume for transport and storage reasons, for increasing stability in chemical substances or for handling thermally sensitive products such as enzymes, proteins or micro-organisms. Spray granulation in the fluidized bed permits liquids to be directly made into free-flowing granulate with specific product properties. Liquids containing solids, such as solutions, suspensions or melts, are sprayed into a fluidized bed system. Due to the high heat exchange the aqueous or organic solutions evaporate immediately, and the solids form small particles as starter cores. These are sprayed with other liquids which in turn, after evaporation, form a hard coating around the starter core. The granules can be very dense because they have grown in layers, and are thus resistant to abrasion. Parameters such as particle size, residual moisture and solids content can be specifically adapted in order to achieve the most varying product properties. Properties such as ability to flow, not abrade, not flake, easily dissolve or be optimally dosed can be imparted to solids using spray granulation. The dust-free granules have a dense surface structure and high bulk density and are low hygroscopic because of their small surface. The optimal solution for converting liquid substances into a solid product form.
Besides complicated fluidized bed spray granulation, there is easy spray drying, which finds large scale applications: from the production of milk powder and bricks to high tech applications.

I am in agreemento with Prof. Verlotski. The most feasible method, for to dry a liquid suspension in order to obtain powder, is spray drying.
